AB  - The electro-physical properties of raw, alkali and oxidatively modified jute fabrics were investigated as complex phenomena of the interactions between the fabrics’ chemical composition, carboxyl group content, crystallinity, structural characteristics, moisture sorption, and frequency of the electric field. At 80% relative air humidity, chemically modified jute fabrics have 38–179% and 1.7–5.4 times higher dielectric loss tangent and effective relative dielectric permeability compared to unmodified. To further improve these properties, fabrics were treated with CuSO4 and Cu-based nanoparticles were in situ synthesized on their surfaces by reduction. A few smaller agglomerates of Cu-based nanoparticles were observed across the alkali modified fabric's surface, while smaller irregularly shaped and larger agglomerates were distributed over the oxidatively modified fabric's surface. Regardless of the type of synthesized nanostructures (metallic Cu, copper oxide (Cu2O or CuO) or their mixtures), excellent fabrics’ effective relative dielectric permeability is guaranteed. Precisely, exploitation in specific conditions that contribute to copper reduction will make jute fabrics able to store 21–163 times more energy from an external electric field than before the exploitation, which will extend their lifetime. On the other hand, with increasing the total content of Cu after the reduction and formation of agglomerates of Cu-based nanoparticles, the movements of cellulose, hemicelluloses, and lignin molecules become difficult resulting in lower energy dissipation within the chemically modified than within unmodified fabric. Applied chemical modification and coating with Cu-based nanoparticles enables designing fabrics with predictable electro-physical properties, which is very important from the application point of view.

AB  - This work aimed to investigate the quality of three plain single jersey weft-knitted fabrics produced from the same flax yarn but with different structural characteristics. The quality of knitted fabrics was evaluated in terms of their electro-physical and compression properties. DC volume electrical resistivity and dielectric properties (effective relative dielectric permeability and AC specific electrical conductivity) were examined in the scope of this investigation. Compressibility and compressive resilience were selected to determine the influence of compression properties on the quality of the knitted fabrics. The current study showed that the sample with the highest stitch density, weight, thickness, moisture content, and the lowest porosity, has the lowest DC volume electrical resistivity and compressibility, but the highest effective relative dielectric permeability, AC specific electrical conductivity, and compressive resilience. Based on the application of the ranking method, the best quality sfowed the knitted fabric with the most compact structure and the highest moisture content; the worst quality was manifested by the knitted fabric with the least compact structure and the lowest moisture content.
AB  - Cilj ovog rada je bio da se ispita kvalitet tri desno-leve potkine pletenine izrađene od istog lanenog prediva, ali različitih strukturnih karakteristika. Kvalitet pletenina je ocenjivan u pogledu njihovih elektrofizičkih i kompresionih svojstava. U okviru ovog istraživanja ispitivana su specifična zapreminska električna otpornost i dielektrična svojstva (efektivna relativna dielektrična propustljivost i specifična električna provodljivost). Kompresibilnost i elastični oporavak su odabrani da bi se utvrdio uticaj kompresionih svojstava na kvalitet pletenina. Sprovedeno ispitivanje je pokazalo da uzorak sa najvećom gustinom petlji, površinskom masom, debljinom, sadržajem vlage i najmanjom poroznošću ima najmanju specifičnu zapreminsku električnu otpornost i kompresibilnost, ali najveću efektivnu relativnu dielektričnu propustljivost, specifičnu električnu provodljivost i elastični oporavak. Na osnovu metode rangiranja ustanovljeno je da najbolji kvalitet ima pletenina najkompaktnije strukture sa najvećim sadržajem vlage; najlošiji kvalitet ispoljava pletenina najmanje kompaktne strukture sa najmanjim sadržajem vlage.

AB  - The influence of the chemical composition on the biosorption potential of waste jute fabric for Ni2+, Cu2+, and Zn(2+)was investigated. The raw jute fabric was treated with sodium hydroxide or sodium chlorite to selectively remove hemicelluloses and lignin, respectively. All jute fabrics were characterized by determination of their chemical composition as well as functional group content. The effects of solution pH, contact time, and initial metal ion concentration on the biosorption from monometallic and polymetallic solution by jute fabrics were investigated. The maximum biosorption capacity for all heavy metal ions was observed at pH 5.5. Concerning the contact time, the raw jute fabric shows more than 72 % of the total uptake capacity of Ni2+, Cu2+, and Zn(2+)within 1 h, while the jute fabrics with lower hemicelluloses and lignin content show between 72-85 % of the total uptake capacity within 3 h. Increased initial metal ion concentration from 10 to 20 mg/lin monometallic solution caused an increase in the total uptake capacity of jute fabrics with lower hemicelluloses and lignin content for 47-69 % (Ni2+), 42-63 % (Cu2+), and 22-37 % (Zn2+). The biosorption capacity of alkali treated jute fabrics was affected by the changes in the total amount of carboxyl and aldehyde groups that accompany the hemicelluloses removal. In the case of the oxidative treatment, the biosorption capacity was affected by the lignin content as well as the amount of introduced carboxyl groups. The best biosorption performance possesses jute fabric with 63.2 % lower lignin content as well as 81.1 % higher amount of carboxyl groups; biosorption capacity toward Ni2+, Cu2+, and Zn(2+)in monometallic solution is about 2.4; 2.2 and 3.5 times higher compared to the raw jute fabric, respectively. All jute fabrics exhibited the same affinity order (which is independent on the initial metal ion concentrations) toward heavy metal ions: Ni2+ gt  Cu2+ gt  Zn(2+)in the case of competitive biosorption. An increase in the initial metal ion concentration for two times in the polymetallic solution caused about a 35-59 % increase in the total uptake capacity of Ni2+, while the total uptake capacities of Cu(2+)and Zn(2+)increased for 19-38 % and 18-65 %, respectively.

AB  - The investigation was performed on three woven mesh fabrics made of polyethylene terephthalate (PET), polyamide (PA) 6.6 monofilaments, and PA 6.6 with carbon filament (CF). The dielectric properties were examined as functions of frequency at room conditions and as functions of frequency and temperature under the vacuum. It was observed at lower frequency higher changes of dielectric permittivity for the sample with CFs at room conditions. For PET and PA 6.6, dielectric permittivity in the vacuum was steady and little lower; furthermore, dielectric spectra showed the existence of gamma-, beta-, and alpha-relaxations. The dc volume electrical resistivity was investigated in the function of relative humidity at room temperature for PA 6.6 and PA 6.6 with CF. For the sample with the CF, a decrease in the dc electrical resistivity of nine orders of magnitude in the direction with CF was registered as compared to the direction without a conductive filament.

AB  - The aim of this work was to investigate the influence of dielectric barrier discharge (DBD) plasma
treatment during 30 and 60 seconds on the fibrous polymeric materials made of cotton, polyethylene terephthalate and polypropylene by recording the frequency dependence of the dielectric loss tangent. Furthermore, the changes in the sample surface morphology were observed using scanning electron microscopy (SEM). By comparing the frequency dependence of the dielectric loss tangent, the same trend with increasing the frequency was noticed for both untreated and treated samples, after 0.5 h as well as 2 and 7 days after plasma treatment. The changes in the value of dielectric loss tangent are small, but it can be noticed that the plasma effect on the cotton sample was maintained after 7 days, which is less noticeable for the samples made of polyethylene terephthalate and polypropylene. The SEM analysis of the cotton sample
showed micro cracks on its surface as a result of plasma etching, while the polyethylene terephthalate fibers appeared darker and rough after the plasma treatment. The changes were more obvious on the samples treated 60 seconds compared to samples treated 30 seconds. There are no significant changes in the polypropylene sample surface morphology.

AB  - Woven jute fabric was treated with sodium hydroxide solution of different concentrations at room temperature, for different periods of time. After that, jute fabrics with gradually decreased content of hemicelluloses were obtained. The changes of the sorption properties (moisture sorption, water retention power and degree of fiber swelling) and dielectric properties (effective relative dielectric permeability, AC specific electrical conductivity and dielectric loss tangent) of alkali treated jute fabrics were investigated. After the alkali treatments, the degree of accessibility of the cell wall components to water vapor increased with increased severity of the alkali treatment. In parallel, the degree of fiber swelling and total water holding capacity of the fabrics were increased. The dielectric properties are very sensitive to fabric structural characteristics, chemical composition and its ability for moisture sorption. Thus, the obtained increase of the effective relative dielectric permeability after the alkali treatments can be attributed to the changes in the structural characteristics and decrease in the content of hemicelluloses, which further contributed to an increased ability for moisture sorption. The changes in the AC specific electrical conductivity can be explained by the fact that the hemicelluloses not only restrict the freedom of the water molecules to take part in the polarization process, they also change the structure in such a way that the mobility of the ions in the electric field is restricted. The values of dielectric loss tangent increased after the alkali treatments due to the increase in the number of polar groups. [GRAPHICS] .

AB  - The main objective of this study was to obtain chitosan functionalized viscose fabric with improved antibacterial properties and washing durability. In this regard carboxyl and aldehyde groups, as binding points for irreversible chitosan attachment into/onto viscose fabric, were introduced by two different pretreatments: 2,2,6,6-tetramethylpiperidine-1-oxy radical (TEMPO) oxidation and coating with TEMPO oxidized cellulose nanofibrils (TOCN). The Fourier transform infrared spectroscopy, elemental analysis, zeta potential measurements, scanning electron microscopy, breaking strength and antibacterial testing were used to evaluate the influence of these pretreatments on chitosan binding, but also on chemical, electrokinetic, morphological, mechanical and antibacterial properties of pretreated and chitosan functionalized viscose fabrics. Washing durability of chitosan functionalized viscose was monitored through changes in the chitosan content, electrokinetic and antibacterial properties after multiple washing. TOCN coating improves mechanical properties of fabric, while TEMPO oxidation deteriorates them. The results show that both pretreatments improve chitosan adsorption and thus antibacterial properties, which are highly durable to washing. After five washings, the chitosan functionalized pretreated viscose fabrics preserve their antibacterial activity against Staphylococcus aureus, while antibacterial activity against Escherichia coli was lost. TOCN coated and chitosan functionalized viscose fabric is a high value-added product with simultaneously improved antibacterial and mechanical properties, which may find application as medical textiles.

AB  - Textile materials like woven, knitted and nonwoven fabrics are good insulators with very high
electrical resistance. It is known that dielectric properties (effective dielectric permeability, electrical
conductivity, and dielectric loss tangent) and electrical resistivity (volume resistivity and surface
resistivity) of fabric are depending on several factors such as fiber type, fabric structure, moisture
content of the material, air humidity, temperature, etc. The purpose of this investigation is to study the
influence of the different content of viscose and polypropylene as well as the type of web bonding on
the dielectric loss tangent and volume electrical resistivity. Also, the dielectric loss tangent was
analyzed over a range of frequencies from 30 Hz to 140 kHz. Three investigated nonwoven fabrics
were mechanically and thermally bonded, and one of the samples was additionally chemically
bonded. The investigations were realized at 40 % relative air humidity.
Conducted analyses show that at frequencies below 100 Hz all investigated samples have
higher, while at higher frequencies, the investigated samples show lower values of loss tangent.
Namely, gradually decrease of the loss tangent value with the increase in the frequency from 30 Hz to
140 kHz was registered. The highest loss tangent value shows the sample with the highest viscose
fiber content and thus the highest number of polar hydroxyl groups. The smallest loss tangent value
was registered for a sample which was additionally chemically bonded.
Results obtained for the volume electrical resistivity was in accordance with the loss tangent
values. The lowest resistivity value was recorded for sample with the highest viscose fiber content
both in the machine direction as well as in the cross direction (5.27 GΩ∙cm and 5.03 GΩ∙cm,
respectively), while the highest resistivity value was registered for additionally chemically bonded
sample also in both investigated direction (11.84 GΩ∙cm and 12.51 GΩ∙cm, respectively). Some little
differences in volume electrical resistivity in the machine and in cross direction are probably due to
the fiber orientation in the samples and the number of contacts established between the fibers, because
better contact between fibers causes an easier flow of charge.

AB  - In this work, sorption and dielectric properties of viscose/polypropylene multipurpose nonwoven fabrics were examined. The analysis of sorption behavior showed that the changes of the water absorptive capacity, the height of capillary rise and water retention value are in a function of viscose fiber content, total porosity, the pore size and used web bonding process. It is observed that dielectric properties at frequencies from 30 Hz to 140 kHz, for samples exposed to different relative air humidity and wet samples, are dependent on viscose fiber content, web bonding process, frequency of electric field and bulk free water content. The effective dielectric permeability of wet samples rapidly decreases with an increase in frequency up to 3 kHz while spectra of the AC specific electrical conductivity showed a plateau above 13 kHz. It is also observed that the dielectric properties of wet samples increase by several orders of magnitude compared to dry samples.

AB  - The application of woven fabrics as the substrate materials for electronic products causes the need to examine their electrical properties at various external effects. This paper presents the results of electrical properties of the fabrics of cotton, cotton/polyethyleneterephtalate (PET) and PET. Dielectric loss factor and dielectric permeability were analyzed in a wide range of temperatures and frequencies. Relaxation peak which appears in this measuring region was identified as the secondary beta-relaxation. At different frequencies the dielectric permeability has been analyzed at a different relative humidity at room temperature. At the higher values of relative humidity with the increase of frequency leads to greater reduction of the dielectric permeability and this is more prominent in the samples of cotton and cotton/PET blend. The dc volume resistivity has been investigated in the function of relative humidity at room temperature and interpreted by the raw composition and the structural properties. On the basis of the obtained results, it was concluded that on the electrical properties of cotton/PET blend, cotton has greater impact i.e. the component with the higher dielectric permeability value and smaller dc volume resistivity value.
