s:Polyether/epoxy-modified polysiloxane was prepa red by the hydrosilation of silicone fluid containing hydrogen with epoxide containing vinyl group and polyether containing vinyl group at Pt-catalyst.And polyether/amino-modified polysiloxane was prepared by the reaction of polyether/epoxy-modified polysiloxane with organ-amines.The effects of viscosity of silicone fluid containing hydrogen and amino structure,silicon content,pH,as well as Si—H bonds residuary in polysiloxane backbone on PEAS performance were studied.The results showed that compared with polyether/epoxy-modified silicone CGF the polysiloxane containing piperazinal and polyether could impart better softness,smoothness,as well as whiteness to fabrics when the silicon content is 2595% and the viscosity is above 10 000 mPa·s,with the rewettiability of fabrics finish ed with PEAS being 1″81.
