| Abstract: | In order to increase the added value of cotton fabrics and improve its adsorption to modifying components, sodium periodate was used for oxidation treatment to increase the adhesion of cotton fiber. Silver nanowires (AgNWs) were then prepared by one-step polyol reduction method at 160 ℃ and dispersed in anhydrous ethanol. With a cotton fabric as the substrate, AgNWs was finished on the surface of the fabric by the impregnation drying method. The finished cotton fabric was characterized, and its UV resistance, conductivity and washing resistance were tested. The results show that with the increase of AgNWs concentration, the electrical conductivity of the fabric increases by more than 80%. When the AgNWs concentration is 10 g/L, the UV protection factor (UPF) value reaches 55, and the UV transmittance is reduced to less than 2.5%. The washing resistance of the modified cotton fabric is improved by 20% after the oxidation treatment, and the UPF value of the modified fabric after three times of washing reaches 46.51. The flexible conductive cotton fabric can be applied to flexible electronic textiles and anti ultraviolet products. |
