Effect of organosilicon resin containing disulfide bonds on elastic properties of cotton fabric

Abstract

Cotton fabrics are popular for their excellent properties, but their property of creasing easily largely limits the wide application of cotton fabrics. In this paper, an organosilicon resin emulsion containing disul de bonds was prepared with epoxy-terminated silicone oil and 4,4-diaminodiphenyldisul de (AFD) as raw materials, and it was used as a nishing agent for the elastic nishing of cotton fabrics. The effects of raw material ratio on the elastic properties of organosilicon polymer lm and the effects of emulsi er dosage and emulsi cation time of emulsion polymerization on the properties of organosilicon resin emulsion were studied. In addition, the effects of organosilicon nishing agent dosage, baking temperature, and baking time on the elastic properties of cotton fabric were also studied. The research results show that the average particle size of the prepared organosilicon resin emulsion is about 250 nm, the particle size distribution is concentrated and the emulsion is stable. The delayed elastic recovery angle of the cotton fabric treated with an organosilicon nishing agent can reach 185°, showing excellent high delayed elasticity. At the same time, it was found that the nished cotton fabric exhibited an excellent and special temperature-responsive shape memory function based on the existence of disul de bonds in the organosilicon polymer network structure.
