Water-repellent agent composition for fibers, water-repellent textile product, and production method for water-repellent textile product

Abstract

This water-repellent agent composition contains: an acrylic resin having a constituent unit derived from a (meth)acrylic acid ester monomer (A) represented by general formula (A-1) and/or a urethane resin having a structural unit derived from a polyfunctional compound represented by general formula (I-1) and a structural unit derived from an isocyanate compound represented by general formula (II-1); an organo-modified silicone represented by general formula (L-1); and a wax. In formula (A-1), R1 represents hydrogen or a methyl group, R2 represents an optionally substituted monovalent hydrocarbon group having 12 or more carbon atoms. In formula (I-1): R31[-W1-R32]d[-V1]e, d represents an integer of one or more, e represents an integer of two or more, (d+e) is 3-6, R31 represents a (d+e)-valent organic group, W1 represents a divalent group which is an ester group, an amide group, a urethane group, or a urea group, R32 represents a straight-chain or branched monovalent hydrocarbon group having 8-24 carbon atoms, and V1 represents a hydroxyl group, an amino group, or a carboxy group. Note that two or more among the e-number of V1's are a hydroxyl group and/or an amino group. In formula (II-1): R33[-NCO]f, R33 represents an f-valent organic group, and f represents an integer of 2-7. In formula (L-1), R220, R221, and R222 each independently represent a hydrogen atom, a methyl group, an ethyl group, or an alkoxy group having 1-4 carbon atoms, R223 represents a hydrocarbon group having an aromatic ring and having 8-40 carbon atoms, or an alkyl group having 3-22 carbon atoms, R230, R231, R232, R233, R234, and R235 each independently represent a hydrogen atom, a methyl group, an ethyl group, an alkoxy group having 1-4 carbon atoms, a hydrocarbon group having an aromatic ring and having 8-40 carbon atoms, or an alkyl group having 3-22 carbon atoms, a1 represents an integer of zero or more, a2 represents an integer of one or more, (a1 + a2) is 10-200, in the case where a1 is two or more, respective R220's and respective R221's may be the same or different from each other, and in the case where a2 is two or more, respective R222's and respective R223's may be the same or different from each other.

Description

technical field [0001] The present invention relates to a water repellent composition for fibers, a water repellent fiber product and a method for producing the water repellent fiber product. Background technique [0002] Conventionally, a fluorine-based water repellent having a fluoroalkyl group has been known as a water repellent used in water repellent finishing, and by treating the fiber surface with this fluorine-based water repellent, a fiber product imparted with water repellency can be obtained. However, although fiber products treated with fluorine-based water repellents exhibit excellent water resistance, concerns about the environmental load of the long-chain fluoroalkyl compounds used have become clear. A non-fluorine-based water repellent that exhibits high-performance water repellency comparable to fluorine-based water repellents. [0003] Therefore, research has been conducted on non-fluorine-based water repellents not containing fluorine in recent years. Fo...
