Pozycja Moisture transport in woven fabrics containing cotton fibers(Wydawnictwo Politechniki Łódzkiej, 2022) Kamińska, Dominika; Matusiak, MałgorzataCotton is currently the most commonly used raw material of natural origin in a production of clothing. Due to its very good hygroscopic properties, it is also often used in production of underwear, bandages etc. A liquid moisture transport plays a crucial role in shaping a physiological comfort. As part of this study 2 pairs of woven fabrics containing cotton fibers with twill 3/1 S weaves were tested in the range of their ability to moisture transport in the form of liquid. Moisture transport is the fabric's ability to wick moisture away from the body. The investigation were carried out on the Moisture Management Tester. The investigations allowed to assess the moisture transport of individual fabrics.Pozycja Investigation of an Innovative “Cotton Hollow” Yarn(Instytut Biopolimerów i Włókien Chemicznych (IBWCh) , Łódź, Polska, 2014) Andrysiak, Jerzy; Sikorski, Krzysztof; Wilk, Edward; Matusiak, MałgorzataCotton is a basic raw material processed in the textile industry all over the world. Some new cotton products have been developed thanks to the inventions and efforts of scientists and engineers dealing with cotton. One of the innovative cotton products is SPINAIR yarn by Kurabo (Japan). It is so called “hollow” yarn made of cotton and PVA fibres. PVA fibres are introduced into the yarn during the spinning process. Next they are dissolved and removed in fabric finishing, thanks to which in the final product the yarn is composed only of cotton fibres. The yarn has been developed to improve the thermal insulation of cotton fabrics. Due to the dissolving of PVA fibres, the structure of yarn and fabrics made of it is loose and porous. The air trapped inside the yarn between the cotton fibres increases the thermal resistance of fabrics. Within the framework of the work presented composite “hollow” yarn 42 tex made of cotton (80%) and modified PVA (Polyvinyl alcohol) fibres (20%) was investigated within the range of its structural, mechanical and technological parameters. Woven fabric was then manufactured with the application of the 42 tex CO80/ PVA20 yarn in the weft direction. Investigation of the manufactured woven fabric with Alambeta confirmed that fabric with weft yarn 42 tex CO80/PVA20 is characterised by a higher thermal resistance and warmer sensation while touching than that made of 42 tex cotton rotor yarn in the weft.
