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.

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. Pored toga, rezultati su ukazali na efekte koje struktura pređe ispoljava u pogledu toplotnog komfora pletenina. Upotrebljena vlakana su manifestovala svoj uticaj na termička svojstva pletenina i njihovu sposobnost da propuštaju vazduh i vodenu paru kroz različitu sposobnost pakovanja vlakana u pređe. Ovim istraživanjem je potvrđena mogućnost dobijanja pletenina na bazi mešavine konoplje i poliakrilonitrilnih vlakana sa zadovoljavajućim svojstvima toplotnog komfora.
