    Thermal-Insulation Properties of Multilayer Textile Packages
    (Wydawnictwo Politechniki Łódzkiej - Wydział Technologii Materiałowych i Wzornictwa Tekstyliów, 2014) Matusiak, Małgorzata; Kowalczyk, Sylwia
    Thermal-insulation properties of textile materials play a significant role in material engineering of protective clothing. Thermal-insulation properties are very important from the point of view of thermal comfort of the clothing user as well as the protective efficiency against low or high temperature. Thermal protective clothing usually is a multilayer construction. Its thermal insulation is a resultant of a number of layers and their order, as well as the thermalinsulation properties of a single textile material creating particular layers. The aim of the presented work was to investigate the relationships between the thermal-insulation properties of single materials and multilayer textile packages composed of these materials. Measurement of the thermal-insulation properties of single and multilayer textile materials has been performed with the Alambeta. The following properties have been investigated: thermal conductivity, resistance and absorptivity. Investigated textile packages were composed of two, three and four layers made of woven and knitted fabrics, as well as nonwovens. On the basis of the obtained results an analysis has been carried out in order to assess the dependency of the resultant values of the thermal-insulation properties of multilayer packages on the appropriate values of particular components.

    Investigation of an Innovative “Cotton Hollow” Yarn
    (Instytut Biopolimerów i Włókien Chemicznych (IBWCh) , Łódź, Polska, 2014) Andrysiak, Jerzy; Sikorski, Krzysztof; Wilk, Edward; Matusiak, Małgorzata
    Cotton 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.

    Investigation of Naturally Coloured Cotton of Different Origin – Analysis of Fibre Properties
    (Instytut Biopolimerów i Włókien Chemicznych (IBWCh) , Łódź, Polska, 2014) Matusiak, Małgorzata; Frydrych, Iwona
    Naturally coloured cotton is naturally pigmented fibre that grows in shades of brown and green. Because the colour is present in the fibres, fabrics made of them do not have to be dyed. The elimination of the dyeing process can save up to one half of the cost of preparing textiles and also lowers disposal costs for toxic dye waste dangerous to human health and the environment. In spite of the economic and ecological benefits resulting from the elimination of the dying process, the application of the naturally coloured cotton in the world textile industry is still limited. The low quality of fibres is considered as the most important reason for the limitation of naturally coloured cotton application. The aim of the work presented was to investigate the quality of naturally coloured cotton of different origin as well as to show the potential of the naturally coloured cotton as an excellent raw material for manufacturing ecological textiles of good quality and attractive design.
