摘要：

Using α,ω-dihydroxydimethylpolysiloxane(WS-62M),cyclohexylaminosilane coupling agent and epoxy group polyether as raw materials,polyether modified aminopolysiloxane was synthesized,which was applied to fabric softening finish.The structure was characterized with IR spectrum.The optimum synthetic the epoxy polyether modified aminopolysilxane conditions were determined: the reaction temperature of secondary amino silicone oil synthesis was 85 ℃,and the molar ratio of epoxy polyether and amino silicone oil was 0.7:1.The finished white cotton fabric had good handle,whiteness and hydrophility,and had better absorbency and anti-yellowing property than the traditional modified silicone oil.
