    Hydrophobic and conductive cotton fabric with silver nanowires and silanes
    (Wydawnictwo Politechniki Łódzkiej, 2022) Nejman, Alicja; Celichowski, Grzegorz; Cieślak, Małgorzata
    Hydrophobic and conductive cotton (CO) fabric was prepared by coating with silver nanowires (AgNWs) and mixture of two silanes: 3-aminopropyltriethoxysilane (APTES) and diethoxydimethylsilane (DEDMS). New functionalization method was developed in which the silanes mixture was applied to the previously deposited AgNWs layer. The AgNWs/silanes modified fabric showed hydrophobic properties. The water contact angle was 130 ± 1deg. The surface free energy was approximately 16 ± 1 mJ/m2, while for unmodified fabric it was 42 ± 1 mJ/m2. Unmodified fabric was nonconductive, the electrical surface (Rs) and volume (Rv) resistances was 3.9 x 1011 ± 3.4 x 1010 Ω and 2.2 x 1010 ± 1.7 x 109 Ω, respectively. After AgNWs/silanes modification it decreased to 7.5 x 102 ± 3.6 x 101 Ω and 7.0 x 102 ± 1.0 x 101 Ω, respectively. Hydrophobic and conductive cotton fabric has the potential to use in new specific purposes.

    Influence of yarn fineness on fabric conductivity
    (Wydawnictwo Politechniki Łódzkiej, 2022) Schwarz, Ivana; Brnada, Snježana; Kalazić, Ana; Badrov, Tea; Kašaj, Andreja
    The application of conductive fabrics is extremely wide and applies primarily to areas such as protective textiles, smart textiles, e-textiles, textile for medical applications, etc. The influence of conductive spun yarn, made from carbon and aramid fibres blend, on fabrics conductivity was investigated. Three types of fabrics, with different fineness and structures of conductive yarns in the weft direction were woven and tested. The relevant properties of the yarns were investigated, as well as the properties of the woven fabrics, which fully contribute to the fabrics conductivity properties. This was confirmed by testing the surface and vertical electrostatic resistance of the fabric, i.e. conductivity.
