Title:
ANTIBACTERIAL POLYACRYLONITRILE-BASED SYNTHETIC FIBER, METHOD FOR PRODUCING SAME, AND HEADDRESS PRODUCT
Document Type and Number:
WIPO Patent Application WO/2023/190761
Kind Code:
A1
Abstract:
Provided is an antibacterial polyacrylonitrile-based synthetic fiber suitable for synthetic hair that is superior in an antibacterial property and texture, a method for producing the fiber, and a headdress product comprising the fiber. The present invention employs an antibacterial polyacrylonitrile-based synthetic fiber in which a quaternary ammonium salt (B) represented by formula (1) (wherein: R1 is an alkyl group having 8 to 18 carbon atoms; R2 to R4 are respectively independently a methyl group, an alkyl group having 8 to 18 carbon atoms, a 3-(trihydroxysilyl)propyl group, a 3-(trimethoxysilyl)propyl group or a benzyl group; n is 1 or 2; and Xn- is an inorganic acid ion selected from a group consisting of a bromide ion, a chloride ion, a fluoride ion, a hydroxide ion, a carbonate ion, a sulfate ion, a nitrate ion, a phosphate ion, and a borate ion, a monoalkyl phosphate ion having an alkyl group having 1 to 3 carbon atoms, or a dialkyl phosphate ion having an alkyl group having 1 to 3 carbon atoms), and a non-ionic surfactant (C) are attached to a polyacrylonitrile-based synthetic fiber (A), wherein: the non-ionic surfactant (C) contains a sorbitan fatty acid ester (C1) and polyoxyethylene triglyceride (C2); the amount of the quaternary ammonium salt (B) attached is between 0.05 mass% and 0.3 mass% both inclusive with respect to a total mass of the antibacterial polyacrylonitrile-based synthetic fiber; and the amount of the non-ionic surfactant (C) attached is between 0.15 mass% and 0.9 mass% both inclusive with respect to the total mass of the antibacterial polyacrylonitrile-based synthetic fiber.
