摘要
Abstract
A new kind of terminated polyether modified polysiloxanes (TMPES) was synthesized by hydro-silylation of the bis-dimethylhydrogen siloxyl-terminated polydimethylsiloxane (PHMS) with al ylpolyoxyethyl-ene ether (FAE-10) in the presence of a platinum catalyst. The optimum experimental conditions were opti-mized: FAE-10 to PHMS was n(C C)∶n(Si-H)=1.1∶1.0, reaction temperature was 90 ℃, reaction time was 4 h. And TMPES with a light shade of yel ow, water-soluble and apparent liquid were obtained. The chemical structure of TMPES was characterized by IR. The surface properties of TMPES were measured, and its applica-tion properties in cotton fabric finishing were investigated. The results showed that TMPES exhibited excel ent surface activity. The critical micel e concentration (cmc) of TMPES solution was 0.8 g/L and the surface tension (γcmc) of TMPES solution in cmc was 26.7 mN/m. When the dosage of TMPES increased, the bending rigidity of the treated cotton fabric decreased, the softness of the treated cotton fabric was enhanced, and the white-ness and wettability was nearly unchanged.关键词
