ABSTRACT:
The silicone-based fiber finishing agent is particularly suitable for synthetic fiber-made fabric materials such as waddings of polyester fibers to impart excellent softness and smoothness in touch and free from yellowing even by heating with high resistance against dry cleaning. The fiber finishing agent comprises (A) an organopolysiloxane of a substantially linear molecular structure terminated at each molecular chain end with a silanolic hydroxy group or alkoxy group and having at least one amino-substituted hydrocarbon group bonded to the silicon atom in a molecule, (B) an epoxy-containing alkoxy silane compound such as methyl dimethoxy 3-glycidyloxypropyl silane and (C) an epoxy-containing organic compound free from silicon such as glycidyl alcohol and glycidyl methacrylate.
