摘要: The present invention addresses the problem of improving the antistatic properties and flexibility of fibers to which a treatment agent for synthetic fibers is applied. A treatment agent for polyester synthetic fibers according to the present invention contains a silicone (A), a silicone (B), an anionic component and a silicone (D), while optionally containing a silicone (C). The silicone (A) is a modified silicone that has an amino group in each molecule. The silicone (B) is a silane coupling agent which does not contain an epoxy group but contains at least one functional group that is selected from among a methoxy group, an ethoxy group, an amino group and an isocyanate group in each molecule. The silicone (D) is a silanol-modified silicone that has a number average molecular weight of not less than 20,000 but less than 200,000. The silicone (C) is composed of at least one material that is selected from among a silicone resin, dimethyl silicone and an alkyl-modified silicone (excluding the silicone (A) and the silicone (D)). The content ratio of the silicone (C) in the treatment agent for polyester synthetic fibers is less than 10% by mass.

摘要: The present invention addresses the problem of improving: the stability of a treatment agent for synthetic fibers; and the antistatic properties and flexibility of fibers to which a treatment agent for synthetic fibers is applied. A treatment agent for polyester synthetic fibers according to the present invention contains a silicone (A), a silicone (B), a nonionic surfactant and an anionic component, while optionally containing a silicone (C). The silicone (A) is a silanol-modified silicone that has a number average molecular weight of not less than 50,000 but less than 200,000. The silicone (B) is a silane coupling agent which does not contain an epoxy group but contains at least one functional group that is selected from among a methoxy group, an ethoxy group, an amino group and an isocyanate group in each molecule. The silicone (C) is composed of at least one material that is selected from among a silicone resin, dimethyl silicone and an alkyl-modified silicone (excluding the silicone (A)). The content ratio of the silicone (C) in the treatment agent for polyester synthetic fibers is less than 10% by mass.
