A synthetic fiber treatment agent composition capable of providing synthetic fibers, particularly synthetic fiber padding, with a better hand, smoothness, repulsion, and the like. The composition comprises an amino group-containing polyorganosiloxane with a high amino group content and specific terminal groups, and an amino group-containing polydiorganosiloxane with a low amino group content or a polydiorganosiloxane with no amino groups.

Synthetic fiber treatment agent composition

A polyester fiber treatment composition is capable of imparting good handle to polyester fiber, particularly polyester fiber wadding, padding, or fill, and consists of a water-based emulsion containing (A) an aminofunctional organopolysiloxane endblocked by alkoxy groups at its molecular chain terminals, (B) an aminofunctional organopolysiloxane endblocked by silanol groups at its molecular chain terminals, (C) a nonionic surfactant, and (D) water.
