Abstract: Hydroxysilicone oil was emulsified and polymerized with silicone coupling agent carrying with a amino-group and polyether-group under certain conditions.The influences of reaction temperature and time and the dosage of catalyst on the viscosity and yellowing of the product were studied and the optimum conditions of synthesis reaction were determined by orthogonal experiment method.Moreover,a comparative analysis of this modified softener and the products of the same kind both at home and abroad in terms of handle,whiteness,tearing strength and anti-crease properties was conducted.The results showed that the fabric treated with this modified softener has excellent hand feeling and good whiteness (81.3%),and its tearing strength increased by 22% and the crease recovery angle raised by 9% as compared with the fabrics treated with ordinary softeners.
