AB  - Heat and mass transfer through textile fabrics play a crucial role in achieving optimal thermal comfort perception by a person. The governing properties of textile fabrics by which they influence heat and mass transfer from the human skin to the environment are thermal transport capacity, water vapor permeability, and air permeability. The transfer of liquid moisture through textiles is important for thermal comfort during frequent changes in physical activity or climate. Despite numerous studies on the transport properties of textile materials over the past years, investigation in this subject area is still needed. This special issue includes five articles that offer valuable information on the subject. Both commercial and specially designed textile structures were investigated within the presented studies with the ambitious goal of providing a new understanding of their transport properties. Within the first four papers presented, certain aspects of heat and mass transfer through textile materials were analyzed at the three scale levels: microscopic (fiber type), mesoscopic (yarn geometry and fineness), and macroscopic (fabric porosity) levels. The fifth article dealt with the influence of the seam type and the sewing thread fineness on the transport propert ies of the seamed structure.

AB  - This study investigates the effect of surface modification by deposition of electrospun fibers on properties and performance of three different microporous polypropylene/polyethylene (PP/PE) commercial nonwoven membrane supports (Novatexx 2430, 2465 and 2473). Polyamide (nylon 6) nanofiber webs with a small number of defects and fibers of about 100 nanometer diameter were successfully deposited onto a surface of the selected membrane supports. FESEM was used to examine microstructure and morphology of the unmodified substrates and the prepared composite two-layer membranes. DSC was applied to investigate thermal stability and FT-IR analysis to confirm the chemical composition of the studied membranes. Saline water permeability tests of the prepared two-layer composite membranes were carried out. The largest pressure difference was measured for PA nanofiber/Novatexx 2430 sample, which was ascribed to a denser net structure of the membrane support and possibly to the newly formed layer of dissolved salts on the membrane surface.

AB  - In the present research, folding of yarns was applied as a method for designing thermal transport characteristics of hemp-based knits. The rib-knitted fabrics were made by combining one of two cotton two-folded yarns (differing in folding twist) with one of the two complex hemp yarns. The parameters describing the thermal properties in the steady-state and transient regimes of heat transfer were determined. The results indicated that the packing density of the fibers in the yarn plays a crucial role in the heat conduction through the fabric. The two-assembled hemp component appeared to be the main heat conductor in the knitted fabrics containing it. Between the knits composed of the two-folded hemp and two-folded cotton yarns, that having two-folded more twisted cotton yarn as a component was characterized by higher thermal conductivity. The higher thermal conductivity resulted in higher thermal absorptivity, but not necessarily in higher thermal diffusivity, as the increased volumetric heat capacity may limit the speed of heat spreading through the fabric. Therefore, the knits containing two-assembled hemp yarn differed in thermal diffusivity despite their similar thermal conductivity. Both knits with the two-folded more twisted cotton yarn as a component had similar thermal diffusivity despite their different thermal conductivity.

AB  - Liquid transport in textile fabrics determines thermal comfort during high physical activity of a person when liquid perspiration is produced and needs to be transferred away from the skin to keep the thermal balance. In this investigation, an attempt was made to get some indications of how the combination of the fabric composition, geometry and dimensional stability, and the moisture content influences liquid transfer properties of plain weft knitted fabrics. Therefore, the knitted fabrics made from pure hydrophilic (hemp fibres), pure hydrophobic (acrylic fibres) and a hydrophilic/hydrophobic (hemp/acrylic) fibre blend underwent a trial wear and care period. The Malden Mills water distribution test was performed for the knitted fabrics with different moisture contents (0-30 %) in order to evaluate the effect on liquid transfer properties. Water transfer ability and water holding capacity of the knitted fabrics were also determined after undergoing the wear trial test. The obtained results were analysed with respect to macro and micro scales of porosity of knitted fabrics. It has been shown that the geometric configuration of the complex porous network in knitted fabrics influenced their liquid transfer properties in the whole moisture content range regardless of the composition. Despite the reconfiguration of the pore system in the knits during the trial period, their liquid transfer properties were still dependent on the pore size and distribution.

AB  - The development of automated software and the device for determination of wicking of textile materials, using open-source ImageJ libraries for image processing, and newly designed additional algorithm for the determination of threshold, is presented in this paper. The description of the device, design of the open-source software "Kapilarko", as well as an explanation of the steps: image processing, threshold determination and reading of wicking height, are provided. We have also investigated the possibility of using the artificial neural networks for automatic recognition of the wicking height. The results showed that the recognition of the wet area of the sample, based on the application of artificial neural networks was in a very good agreement with the experimental data. The device's utility for the measurement of wicking ability of textile materials was proved by testing various knitted fabrics. The constructed device has the advantages of providing automated measurement and minimization of the subjective errors of the operators; extremely fast or long-term measurements; digital recording of results; consistency of experimental conditions; possibility of using water instead of colors and, last but not least, low cost of the device. Considering the importance and frequent measurements of wicking ability of textile materials, the advantages of the presented device, as well as the fact that commercial software without publishing the source-code, are used for most of the available devices, we believe that our idea to design the automated software and device by applying the "open-source" approach, will be of benefit to scientists and engineers in using or improving wicking experiments.

AB  - Considering specific mechanical, hygienic and protective properties of hemp, as well as its positive
sustainability aspects, the raising role of hemp fibres in the textile sector can be expected. The limited
deformability of hemp fibres, which has a negative influence on the tactile comfort, can be overcome by
blending them with other soft fibres. In this project, an attempt was made to overcome this limitation by
blending them with soft and warm acrylic fibres so as to avoid any chemical treatments with softeners.
The composition of the knitted fabrics was designed at the knitting production stage, offering the
knitwear factories a new possibility for fibre blending. The produced single jersey knitted fabrics were
evaluated in terms of their thermal behaviour in both steady-state and transient conditions. Since this
type of knitted fabrics is prone to dimensional changes and distortion upon repeated laundering, the
undershirts made thereof were subjected to the wear trial test (repeated wear and care cycles) in real life
situations, in order to assess changes in the thermal properties of the knitted fabrics. Observed changes
in the geometry of the knitted fabrics and morphology of the fibres after a period of wear and care of the
undershirts have had positive effects on the thermal properties of the hemp based knits. Hemp/acrylic
knitted fabric has undergone the biggest change in the geometry, but moderate change in thermal
properties comparing to those of the hemp knit. The values of thermal parameters of the hemp/acrylic
knit after repeated wear and care cycles which were in the range of those of the hemp knit before the
wear trial test, confirmed that the hemp-blend proposed by this study would follow the trend of good
hemp thermal behaviour in terms of comfort at the exploitation stage. The presented results offer a
product design strategy to increase the performance, economic and environmental benefits for both the
producers and consumers.

blending them with other soft fibres. In this project, an attempt was made to overcome this limitation by
blending them with soft and warm acrylic fibres so as to avoid any chemical treatments with softeners.
The composition of the knitted fabrics was designed at the knitting production stage, offering the
knitwear factories a new possibility for fibre blending. The produced single jersey knitted fabrics were
evaluated in terms of their thermal behaviour in both steady-state and transient conditions. Since this
type of knitted fabrics is prone to dimensional changes and distortion upon repeated laundering, the
undershirts made thereof were subjected to the wear trial test (repeated wear and care cycles) in real life
situations, in order to assess changes in the thermal properties of the knitted fabrics. Observed changes
in the geometry of the knitted fabrics and morphology of the fibres after a period of wear and care of the
undershirts have had positive effects on the thermal properties of the hemp based knits. Hemp/acrylic
knitted fabric has undergone the biggest change in the geometry, but moderate change in thermal
properties comparing to those of the hemp knit. The values of thermal parameters of the hemp/acrylic
knit after repeated wear and care cycles which were in the range of those of the hemp knit before the
wear trial test, confirmed that the hemp-blend proposed by this study would follow the trend of good
hemp thermal behaviour in terms of comfort at the exploitation stage. The presented results offer a
product design strategy to increase the performance, economic and environmental benefits for both the
producers and consumers.",

AB  - In the last decades the media have highlighted the ozone depletion as major environmental problem resulting in an increase in ultraviolet radiation (UVR) reaching the earth's surface. Besides the beneficial effects of human exposure to UVR, this radiation is capable of causing damage to human population. The healthy lifestyle is becoming widely accepted by the public, and the UV protection provided by clothing becomes the significant subject of interest of the producers and consumers of textile fabrics. Natural cellulose fibres are commonly used in summer clothing due to their excellent comfort properties. However, these fibres have very poor UV protection ability. In this project, the UV protection property of textile fabrics made of natural and regenerated cellulose fibres have been compared and analysed in order to highlight the potential of hemp fibre for the development of more sustainable and healthy functionalized (UV protective) textile products. A group of homogeneous and blended cellulose textile fabrics were manufactured in a knitwear factory, evaluated in terms of the structure, and spectrophotometrically assessed to indicate their UV protection ability. The knitted fabrics merited sun protection ratings of "good" for pure hemp, through "very good" for viscose containing fabrics to "excellent" UV protection category for cotton based fabrics. Relatively high values of the Ultraviolet Protection Factor (UPF) of the cellulose. materials resulted from the interaction of fibre type, yarn geometry, fabric properties and common processing techniques. The increased UVR transparency of the pure hemp fabric, which resulted from hemp elasticity limitations, overcame by blending with other softer and more elastic cellulose fibres (cotton, viscose). The engineering approach proposed in this study was confirmed as an effective way to create more sustainable (more sustainable resource, pollution prevention, energy and cost savings) textile products with high level of UV protection at the knitting production stage avoiding the use of any additional mechanical and chemical treatments. These results revealed that the future application of hemp fibres in textile products with high added-value are promising. A co-ordinated effort of different subjects of the agro-and textile-industry production chain need to continue so as to overcome the limitations associated with hemp production and fibres properties.

AB  - The aim of this research was to investigate the possibilities of producing comfort hemp containing textile fabrics by assembling a pure hemp yarn with other-fibre containing yarn. The plain knitted fabrics were produced from two-assembled hemp and three variants of cotton yarns which differed in twist level, all having the same linear density. The transport properties (air permeability, water vapour permeability and thermal resistance) of the hemp-based knitted fabrics were quantitatively analysed. The results obtained demonstrated that the introduction of cotton into hemp-based textiles reduces air and water vapour permeability with the downward trend in thermal resistance. The extent to which the transport properties varied among the hemp/cotton knitted fabrics was dependent on the twist intensity of the cotton yarns. Therefore, the yarn assembling technique is an effective way not only to combine different fibre properties but to take advantage of intrinsic properties of component yarns.

In the present work, we have examined the modification of acoustical properties of natural cellulose materials (cotton, hemp) by the radio-frequency argon plasma. We have observed an increase of the sound absorption coefficient due to the plasma treatment for certain range of applied powers. An analysis of elementary processes which happened during plasma-material interaction was conducted. Additional analyses related to material characterizations were performed in order to resolve structural and chemical changes of plasma treated materials. The micro-mechanical modification of treated materials, which happened upon the retrieved structural and chemical changes, was related to the modification of its acoustical properties in order to explain the observed effect.

AB  - Thermal properties of directionally oriented fibrous materials have been investigated in this research with the purpose of considering the influence of fibre arrangement at mesoscopic level. The range of various distributions of fibres in the fibrous materials was obtained by applying different twist intensity during spinning of cotton fibres. From various twisted cotton yarns the knitted fabrics were produced under controlled conditions, so as to obtain as similar as possible constructions. This made possible to obtain the heterogeneity of the porous fibrous structures coming from the mesoscopic level. Thermal conductivity and heat transfer coefficient of the materials were investigated. The results obtained indicate the arrangement of fibres (or their compactness, orientation and migration), which, in turn, was determined by twist intensity (mesoscopic scale), as the key factor influencing thermal properties. Yarn compactness and fibre migration, determined by lateral forces imposed by the twist inserted in yarn, affected variations in structural parameters of the knitted fabrics, and thus influenced their thermal properties. Fibre orientation manifested itself in surface geometry of the yarn was also proved to have a considerable influence on heat transfer properties.

AB  - It is generally accepted that synthetic fibres provide high UV protection capability of textile products, while cellulose fibres have low UV absorption capacity. However, textile materials made of synthetic fibres are not considered to be comfortable for wear in warm weather, whereas cellulose-based textile materials are considered to be much more comfortable to wear, especially in the summer months. For this research, the idea was to produce specially blended knitted fabrics from staple/filament hybrid yarns in order to provide clothing materials with effective UV protection properties, keeping satisfactory comfort properties as well. To obtain hybrid yarns, folding technique was used. The Ultraviolet Protection Factor (UPF), as a quantitative measure of the effectiveness of the material to protect human skin against UV radiation, was determined for the rib knitted fabrics by in vitro test method according to the European standard. The physical properties of the knitted fabrics related to their UV protection properties: bulk density, porosity and air permeability were also determined. The hybrid yarns, from which the rib knitted fabrics were produced, having always hemp yarn as a staple component, caused the differences in UV protection capability of the rib knitted fabrics through the influence of a filament spun component. The hybrid yarn aggregation within knitted fabrics also influenced their UPF values. Even though the pure hemp knitted fabric was marked as "UPF gt 50" (according to European standard) due to natural pigments and lignin in hemp fibres which act as UV absorbers, most of the hemp/filament hybrid yarn knitted fabrics exhibited even higher UPF. Therefore, the engineering approach proposed in this research was confirmed as an effective way to design clothing materials with optimal UV protection capability and other wear comfort parameters.

AB  - In the last years the media have highlighted the damage of the ozone layer and the resulting increase of ultraviolet radiation (UVR) reaching the Earth's surface. Prolonged and repeated, both occupational and recreational, sun exposure of the population causes some detrimental effects. Clothing is considered to be one of the most important tools for UV protection. It is generally accepted that synthetic fibres provide a high UV protection capability of textiles, while cellulose fibres (cotton, linen, hemp, viscose) have a low UV absorption capacity. However, natural pigments, pectin and waxes in natural cellulose fibers, and lignin in hemp fibers, act as UV absorbers having a favorable effect on UPF of grey-state fabrics. Bearing in mind the trend of reintroduction of hemp fibers as a source of eco-friendly textiles, there is a serious lack of study about the potential of hemp materials in terms of UV protection. Folded yarn is a complex yarn composed of two or more component yarns arranged parallel and twisted together to make a "new quality" yarn. Folding of yarns is an operation undertaken in order to modify single-yarn properties to an appreciable degree. There are very few investigations concerning the relationship between the yarn properties and UV protection effectiveness of the fabric made therefrom. In addition, there is no any result in the scientific literature about the influence of yarn folding on UV protection properties of textile materials. Having this in mind, for our research the idea was to evaluate the effect of yarn folding in this regard. The plain knitted fabrics composed of single or two-folded hemp yarn were compared in terms of UV protection properties. The Ultraviolet Protection Factor (UPF), as the quantitative measurement of the material effectiveness to protect the human skin against UVR, was determined for the textile materials by in vitro test method according to the European standard EN 13758. The knitted fabrics construction and physical properties were also determined. Bearing in mind that plain knitted fabrics are particularly susceptible to relaxation, they were subjected to relaxation and shrinkage by wetting process, and testing procedure was repeated on the water-treated samples. The results obtained indicated that the folding operation influences UV protection properties of knitted fabrics through an influence on a loop configuration, i.e. the fabric openness. Relaxation and shrinkage of the knitted fabrics due to wet relaxation caused the reduction of macro-porosity increasing the UPF of the knitted fabrics. Although the knitted fabric produced from single hemp yarn was characterised by higher UPF, the UVR transmittance of the folded hemp yarn knitted fabric after wet relaxation placed it in the "excellent UV protection category" (according to European Standard EN 13758-2). This fact together with the better thermal comfort manifested itself in higher air permeability, confirmed the potential of folding operation in terms of UV protection properties of textile materials.

Folding of yarns is an operation undertaken in order to modify single-yarn properties to an appreciable degree. There are very few investigations concerning the relationship between the yarn properties and UV protection effectiveness of the fabric made therefrom. In addition, there is no any result in the scientific literature about the influence of yarn folding on UV protection properties of textile materials. Having this in mind, for our research the idea was to evaluate the effect of yarn folding in this regard. The plain knitted fabrics composed of single or two-folded hemp yarn were compared in terms of UV protection properties. The Ultraviolet Protection Factor (UPF), as the quantitative measurement of the material effectiveness to protect the human skin against UVR, was determined for the textile materials by in vitro test method according to the European standard EN 13758. The knitted fabrics construction and physical properties were also determined. Bearing in mind that plain knitted fabrics are particularly susceptible to relaxation, they were subjected to relaxation and shrinkage by wetting process, and testing procedure was repeated on the water-treated samples. The results obtained indicated that the folding operation influences UV protection properties of knitted fabrics through an influence on a loop configuration, i.e. the fabric openness. Relaxation and shrinkage of the knitted fabrics due to wet relaxation caused the reduction of macro-porosity increasing the UPF of the knitted fabrics. Although the knitted fabric produced from single hemp yarn was characterised by higher UPF, the UVR transmittance of the folded hemp yarn knitted fabric after wet relaxation placed it in the "excellent UV protection category" (according to European Standard EN 13758-2). This fact together with the better thermal comfort manifested itself in higher air permeability, confirmed the potential of folding operation in terms of UV protection properties of textile materials.",

AB  - Moisture management is a complicated process which is known to be influenced by a variety of fabric characteristics such as fibre nature (hydrophilic or hydrophobic), porosity and thickness. There are different aspects of the moisture management properties of textile materials since water transport in textile materials can be in the form of liquid and vapour. The ability of textile materials to transfer water vapour allows the human body to keep thermal balance due to evaporation. With stronger physical activity of a person when the body produces a large amount of heat, the skin perspiration increases (in order to regulate the body temperature) and liquid sweat should be taken from the skin, otherwise it will worsen the sense of comfort. The aim of this research was to investigate the factors influencing moisture management properties of plain knitted fabrics at the three scale levels, i.e., microscopic (fibre type), mesoscopic (yarn geometry) and macroscopic (fabric porosity) levels. Plain knitted fabrics were produced from the two-assembled hemp, cotton and viscose yarns under controlled conditions so as to be comparable in basic construction characteristics, but varying in yarns geometry. Evaporative resistance test reflecting vapour transport and water distribution test reflecting liquid transport in the knitted fabrics were conducted. To determine the statistical importance of the results, analysis of variance (ANOVA) was applied. As a consequence of the geometry and deformation behaviour of the fibres used and spinning techniques applied, the yarns differed in both packing density and surface geometry, thus determining the pore distribution. Due to loose structure of the cotton yarn, the cotton knitted fabric was characterised by the lowest free open surface (macroporosity) exhibiting the lowest both water vapour and liquid permeability. Although having the highest macroporosity, the water vapour and liquid transport capability of the hemp knitted fabric was lower than that of the viscose knit. The best moisture management properties of the viscose knitted fabric were resulted from viscose affinity for water absorption and increased surface area of the viscose yarn. The results obtained proved that variations in any of the hierarchical structure levels can modify moisture transport ability of textile fabrics. Therefore, the moisture management properties of textile materials can be guided in a desired direction by the appropriate selection of fibres and careful design of yarn structure.

AB  - The difficulty in qualitative evaluation of deformation properties of polymer fibrous assemblies lies in the fact that these materials differ from materials such as wood, concrete, steel, etc., as a consequence of the manifestation of non-linear and plastic deformation. In this work, an attempt was made to quantify repeated compression performance of textile fibrous structures by using the concept of energy. Particular attention was paid to the nonelastic deformation of polymer fibrous systems under compression. Starting from the fact that the compression curve governs the energy-absorption characteristics of materials subjected to repeated stress, deformation components were determined by calculating the energy-absorbing properties and specific parameters the irreversible compression work of all-cycle compression and the compression work of viscoelastic deformation of all-cycle compression. These parameters made it possible to estimate the compression hysteresis and then calculate the share of deformation components at lateral compression of polymer fibrous systems.

Starting from the specific heat of the knitted fabrics determined by a new experimental method based on Newton's cooling rate law, and previously determined thermal conductivity of the knits, their thermal diffusivity and thermal effusivity (absorptivity) have been determined. According to the results obtained, it can be concluded that the structure of the knitted fabrics is responsible for their transient thermal response through thermal conductivity, whereas the composition of the knits influences their dynamic thermal behavior through specific heat. Hemp based textile fabrics are proved to be at a comparable level to other cellulose fabrics from the viewpoint of thermal behavior during the dynamic stage of heat transport.

AB  - Water vapor permeability is a critical parameter in textile fabric comfort evaluation as it represents the ability of the fabric to transfer perspiration coming out of the human body. Clothing materials with high water vapor permeability allow the human body to take advantage of its ability to provide cooling due to the sweat production and evaporation. The influence of several factors such as the fabric structure, thickness, porosity and fiber type on water vapor permeability of common clothing materials was observed by previous researchers. The main objective of this study was to analyze the influence of yarn properties on water vapor permeability of plain knitted fabrics. The range of various yarn structures was obtained by applying different twist intensity during spinning. From three various twisted cotton yarns the knitted fabrics were produced under controlled conditions. Water vapor permeability and air permeability of the knitted fabrics were measured. The results obtained indicated the complex impact of the yarn core and surface geometry on water vapor permeability of plain knitted fabrics. The hairiness of yarn was proved as the parameter with great potential in terms of the water vapor transfer.
AB  - Propustljivost vodene pare je jedan od ključnih parametara u proceni komfora tekstilnog materijala, budući da definiše materijal u pogledu sposobnosti da propušta produkte znojenja ljudskog tela. Odevni tekstilni materijal sa većom propustljivošću vodene pare ne ometa efekte hlađenja ljudskog organizma putem znojenja i isparavanja znoja. Predmet interesovanja dosadašnjih istraživanja odnosio se na uticaj strukture, debljine, poroznosti materijala kao i vrste vlakana na propustljivost vodene pare.

abstract = "Water vapor permeability is a critical parameter in textile fabric comfort evaluation as it represents the ability of the fabric to transfer perspiration coming out of the human body. Clothing materials with high water vapor permeability allow the human body to take advantage of its ability to provide cooling due to the sweat production and evaporation. The influence of several factors such as the fabric structure, thickness, porosity and fiber type on water vapor permeability of common clothing materials was observed by previous researchers. The main objective of this study was to analyze the influence of yarn properties on water vapor permeability of plain knitted fabrics. The range of various yarn structures was obtained by applying different twist intensity during spinning. From three various twisted cotton yarns the knitted fabrics were produced under controlled conditions. Water vapor permeability and air permeability of the knitted fabrics were measured. The results obtained indicated the complex impact of the yarn core and surface geometry on water vapor permeability of plain knitted fabrics. The hairiness of yarn was proved as the parameter with great potential in terms of the water vapor transfer., Propustljivost vodene pare je jedan od ključnih parametara u proceni komfora tekstilnog materijala, budući da definiše materijal u pogledu sposobnosti da propušta produkte znojenja ljudskog tela. Odevni tekstilni materijal sa većom propustljivošću vodene pare ne ometa efekte hlađenja ljudskog organizma putem znojenja i isparavanja znoja. Predmet interesovanja dosadašnjih istraživanja odnosio se na uticaj strukture, debljine, poroznosti materijala kao i vrste vlakana na propustljivost vodene pare. Osnovni cilj ovog rada bio je analiza uticaja svojstava pređe na propustljivost vodene pare glatkih pletenina. Različita struktura pređa je ostvarena primenom različitog intenziteta upredanja. Polazeći od tri različito upredene pamučne pređe u kontrolisanim uslovima su proizvedene glatke pletenine koje su podvrgnute ispitivanju propustljivosti vodene pare i vazduha.

AB  - The compressive nature of textile fabrics is known to be a significant factor influencing tactile comfort. In addition, the transport of the heat through the fabric is considered to be the major factor in thermal comfort. Since the thermal behavior of textile fabrics is highly correlated with thickness and porosity, the changes in bulk density of the fabric caused by the compression force would change the heat flux through the fabric. The operation of yarn folding modifies the existing single yarns to an appreciable degree by combining them together. Therefore, in this study the interaction of thermal and compression properties of textile materials was analyzed from the aspect of the operation of yarn folding. Two jersey knitted fabrics were compared, both knitted under the same conditions, the first produced from the single hemp yarn, and the second one produced from the two-folded hemp yarn. The knitted fabrics exhibited comparable thermal properties. The differences in their compressibility indicated that the reduction of thermal conductivity under the compression force is more likely to be higher for the knitted fabric consisted of the folded yarn. Since the resilience of the knit made from two-folded yarn was comparable to that of the single yarn counterpart, similar permanent changes in thermal behavior of these knits could be expected.
AB  - Mekoća ili kompresibilnost tekstilnih materijala predstavlja važan parametar taktilnog komfora. Pored toga, sposobnost tekstilnih materijala da prenose toplotu smatra se ključnim faktorom toplotnog komfora. Budući da postoji značajna korelacija između toplotnog ponašanja tekstilnog materijala i njegove debljine i poroznosti, promena gustine materijala pod dejstvom kompresionog opterećenja sigurno vodi ka promeni toplotnog fluksa kroz materijal. Operacijom končanja se kombinovanjem jednožičnih komponenata u značajnoj meri modifikuju svojstva pređe. Zbog toga je u okviru ovog rada analizirana interakcija toplotnih i kompresionih svojstava pletenina sa aspekta uticaja operacije končanja pređa. Poređene su dve varijante glatkih DL pletenina, jedna izrađena od jednožične pređe a druga od končane pređe od konoplje, proizvedenih u kontrolisanim uslovima. Pletenine su okarakterisane sličnim toplotnim svojstvima. Razlike u kompresibilnosti pletenina su pokazale da bi smanjenje toplotne provodljivosti tokom kompresionog opterećenja bilo izraženije kod pletenine izrađene od končane pređe. S obzirom na približne vrednosti elastičnog oporavka pletenina, mogu se očekivati trajne promene u toplotnom ponašanju sličnog intenziteta za obe varijante pletenina.

AB  - The sensory perception of textile materials is related to mechanical stimuli due to pressure and friction forces, so the softness and surface properties are considered to be the key parameters of fabric hand. The aim of this study was to investigate the influence of the fibre type, yarn structure and spinning technique on softness and surface properties of plain knitted fabrics. Plain knitted fabrics (jersey) were produced from the two- assembled hemp, viscose and cotton yarns so as to obtain five different fibre content knits: 100% hemp, 100% cotton, 100% viscose, 50%/50% hemp/cotton and 50%/50% hemp/viscose knit. The Kawabata Evaluation System (KES-F) compression and surface testing instruments were used to characterize these properties of the knitted fabrics used. The analysis of variance (ANOVA) was performed to determine the influence of the fibre type, yarn structure and spinning technique on the compression behavior, surface friction and geometrical roughness of the plain knitted fabrics. The analysis of KES data and a statistical method of ANOVA pointed out the influence of the fibre type, as well as yarn core and surface geometry, on compression properties and geometrical roughness of the knitted fabrics.

AB  - The hemp fibres production is characterized by sharp ups and downs, from the extensively growing to their decline in the past decades. Thanks to the unique hemp fibre properties, such as physiological, hygienic and ecological properties, hemp is nowadays reintroduced as a potential fibre source for health clothing textiles. However, hemp fibres have some limitations concerning the coarseness and lower elasticity. The aim of this study was to investigate the possibilities of producing hemp based comfort textile materials by involving soft and warm synthetic (acrylic) yarn. Since the transport of heat, moisture and air through a fabric are the major factors in thermal comfort, thermal properties, water vapor permeability and air permeability of the knitted fabrics were measured by standard testing devices (Permetest and TexTest). Yarn structure seems to be a significant factor influencing thermal comfort properties of knitted fabrics. In this investigation the differences in the yarn structure came from the differences in fibre geometry and properties, and manifested through the packing density into yarn. The hemp+acrylic knitted fabric exhibited transport properties at a comparable level to pure hemp knitted fabric, so the possibility of obtaining hemp+acrylic knitted fabrics with satisfactory thermal comfort properties was confirmed.
AB  - Cilj ovog rada bio je ispitivanje mogućnosti proizvodnje komfornih tekstilnih materijala na bazi konoplje uvođenjem meke i tople poliakrilonitrilne pređe. Operacijom dubliranja pređa homogenog sirovinskog sastava (poliakrilonitrilne i pređe od konoplje) omogućeno je dobijanje pletenina homogenog sirovinskog sastava (100% konoplja, 100% poliakrilonitril) i pletenine od mešavine konoplje i poliakrilonitrilnih vlakana (50% konoplja + 50% poliakrilonitril). Kako su prenos toplote, vlage i vazduha kroz materijal glavni faktori toplotnog komfora, merena su termička svojstva, propustljivost vodene pare i vazduha pletenina upotrebom standardnih uređaja (Permetest, TextTest). Pokazalo se da su ispitivana svojstva konoplja+poliakril pletenine uporediva sa svojstvima pletenine od konoplje.

AB  - In the past decades, the textile market was characterized by a wide range application of man-made fibres. The low-cost and efficient production of these fibres seems to be the main criterion. In addition to economics, some of desired garment properties such as the shape stability, durability and easy care could be easily achieved by introducing man-made fibres into clothing textile materials. However, growing demands for the comfort clothing and environmentally friendly fibres caused the increase of production and application of natural fibres. The hemp fibres production is characterized by sharp ups and downs, from the extensively growing to their decline in the past decades. Thanks to the unique hemp fibre properties and ecological benefits hemp is reintroduced as a potential fibre source for the health human application. Specific hemp-textile characteristics, as their excellent hygienic, thermal, antielectrostatic and ultraviolet radiation-resistant properties determine hemp fabrics as physiological friendly textiles. However, hemp fibres have some limitations concerned with the tactile comfort and subsequent textile transformation. Hemp by nature is coarse and does not have much elasticity. In order to introduce hemp to the area of high quality comfort clothing, which at the moment is governed by cotton, viscose and wool, the properties of hemp fibres must be improved to match to those of traditionally comfort fibres (cotton, viscose and wool). Actual investigations refer to the usage of modified hemp fibres, by special fibre elementarization methods (cottonization), in blends with cotton, wool or synthetic fibres, so that they can be processed on cotton or wool spinning systems to high quality yarns. The aim of this research was to investigate the possibilities of producing comfort textile fabrics incorporating both hemp and other fibres by assembling or folding (ply-twisting) of homogeneous yarns. The techniques applied for a combination of single yarns (assembling and folding) made it possible not only to combine different fibre properties, but to provide the complex yarn differing from single components because of the changes in fibres packing density and orientation. In case of an introduction of different fibre content single components, differing in basic structure themselves, the folded hybrid yarns with the unique properties were obtained. In order to access the influence of yarn structure on comfort properties, plain knitted fabrics were produced from two-assembled hemp, viscose and three variants of cotton yarns differing in twist level, all having the same nominal linear density. In such a way nine plain knitted fabrics were obtained. The tenth variant was produced from twofolded hemp yarn. From the folded hemp based yarns two series of rib (1×1) knitted fabrics were produced differing in stitch density, designed as N (lower) and V (high) density. Mechanical, relaxation and surface properties of the yarns, which were expected to have an influence on comfort properties of the knitted fabrics, were tested. Physical properties of the knitted fabrics the most responsible for the comfort perception were included in this study. In order to evaluate thermal comfort of the knits, basic transport properties: thermal properties, air permeability and water vapour permeability, were investigated. Tactile comfort of the knits was assessed through the mechanical (compression, tensile) and surface properties investigated...
AB  - Tekstilno tržište se poslednjih decenija odlikuje širokom zastupljenošću sintetičkih vlakana, pre svega zbog jeftinije i produktivnije proizvodnje. Pored ekonomskih razloga, tome doprinosi i činjenica da prisustvo sintetičkih vlakana u odevnom tekstilnom materijalu poboljšava stabilnost dimenzija i trajnost i olakšava negu i održavanje odevnih predmeta. Međutim, povećani zahtevi za komfornom odećom, kao i ekološki prihvatljivim tekstilnim vlaknima, izazvali su porast proizvodnje i primene prirodnih vlakana. Proizvodnja i primena vlakana konoplje odlikuje se naglim usponima i padovima, počev od perioda intenzivnog gajenja pa do gotovo potpunog prekida poslednjih decenija. Jedinstvena svojstva i ekološke prednosti vlakana konoplje reafirmišu ih za primenu u oblasti tkz. „zdravog“ odevnog tekstila. Specifična tekstilna svojstva konoplje, kao što su odlična higijenska, toplotna, električna i UV zaštitna svojstva, svrstavaju tekstilne materijale od konoplje u grupu tekstila sa dobrim fiziološkim predispozicijama. Ipak, izvesne slabosti vlakana konoplje, koja se vezuju za tvrdi opip i malu elastičnost, predstavljaju ograničenja sa aspekta taktilnog komfora i dalje tekstilne transformacije. Da bi bi se konoplja uvela u oblast visoko kvalitetnog komfornog odevnog tekstila, u kojoj sada dominiraju pamuk, viskoza i vuna, neophodno je da se svojstva vlakana konoplje modifikuju i usklade sa svojstvima tradicionalnih komfornih vlakana (pamuk, viskoza i vuna). Aktuelna istraživanja se bave mogućnostima upotrebe vlakana konoplje, modifikovanih specijalnim metodama elementarizacije (kotonizovanje), u mešavinama sa pamukom, vunom ili sintetičkim vlaknima, kako bi se upotrebom sistema predenja pamuka ili vune proizvele visoko kvalitetne pređe. Cilj ovog istraživanja bio je ispitivanje mogućnosti dobijanja komfornih tekstilnih materijala mešanjem vlakana konoplje sa drugim vlaknima dubliranjem ili končanjem homogenih pređa. Primenjene tehnike kombinovanja jednožičnih pređa omogućile su ne samo kombinovanje vlakana različitih svojstava, već i dobijanje kompleksnih pređa čija su se svojstva, usled promena u gustini pakovanja i orijentaciji vlakana, razlikovala od svojstava jednožičnih komponenata. Končanjem jednožičnih pređa različitog sirovinskog sastava i strukture dobijene su hibridne pređe jedinstvenih svojstava.

AB  - The protection provided by clothing against ultraviolet (UV) radiation has been the subject of considerable recent research. However, a lack of investigations concerned with the influence of yarn properties on UV protection capabilities of fabrics seems to be present. This study investigated the influence of yarn twist and surface geometry on these properties of fabrics. The gray-state plain cotton knitted fabrics were produced from yarn differing in twist level under controlled conditions, so as to obtain as similar as possible construction of the fabrics. These plain knitted (single jersey) fabrics were spectrophotometrically assessed and UV protection factor was calculated. The results obtained indicated that yarn twist to a great extent influenced the UV protection properties of the knitted fabrics through the influence on yam compactness and surface properties, which in turn influenced the open porosity of the fabric. The results were also interpreted as the consequences of minimal differences between knitted fabrics' construction (different stitch density), which could not be avoided because of the yam twist differences.
