Preparation and application of amino modified polyether-siloxane SEA

In order to overcome the problems of the fabric finished by amino silicone oil on hydrophobicity,poor perspiration absorption,and poor wear-comfort,a novel amino modified polyethersiloxane softener(SEA) was prepared from octamethylcyclotetrasiloxane(D4),(1,3-diglycidoxypropyl) 1,1,3,3-tetramethyldisiloxane(GP-600) and amino-terminated polyoxypropylene(ED600) and applied to the softening finish of pure cotton fabrics.The effect of pre-baking temperature,curing temperature,and the dosage of the softener on the result of the finished fabric was investigated.It was found that when the dosage of SEA 5 g/L,pre-baking temperature 90 ℃ and curing temperature 130 ℃,the finished fabric has the best result in terms of whiteness,softness and hydrophilicity.
