Abstract: In order to overcome the problems of hydrophobic and poor wearing comfort of fabric finishing by amino silicone oil, a novel amino modified polyether-siloxane softer(SEA) was prepared by octamethylcyclotetrasiloxane(D4), (1,3-diglycidoxypropyl) -1,1,3,3-tetramethyldisiloxane (GP-600) and amino-terminated polyoxypropylene (ED600). The finishing effect of SEA used to pure cotton fabric is studied at different pre-baking temperature, baking temperature and softener dosage. The results showed that the the optimal usage of SEA is 5g/L, pre-baking temperature is 90℃ and curing temperature is 130℃, the whiteness , softness and hydroscopicity of the finished fabric have the best effect.
