Fiber-treating agent

Abstract

A fiber-treating agent which improves the water resistance and the heat resistance, imparts heat shape memory ability, and also improves the stretchability and the feel of the surface of a fiber. The fiber-treating agent is a one-part type fiber-treating agent formed of a single composition or a multiple-part type fiber-treating agent formed of a plurality of compositions and comprises the following components (A) to (C) in a total composition: (A): an aromatic compound having one or more vinyl groups or vinylidene groups, and a coordinating functional group; (B): a radical initiator; and (C): water.

1 . A fiber-treating agent, comprising
 component (A): an aromatic compound having one or more vinyl groups or vinylidene groups, and a coordinating functional group;   component (B): a radical initiator; and   component (C): water.   
     
     
         2 . The fiber-treating agent of  claim 1 , wherein the coordinating functional group in the component (A) is a group containing a Pearson's hard base. 
     
     
         3 . The fiber-treating agent of  claim 1 , wherein the coordinating functional group in the component (A) is a group containing COO − , O − , COOH, or OH. 
     
     
         4 . The fiber-treating agent of  claim 3 , wherein the component (A) is at least one selected from the group consisting of
 component (A-1) an aromatic compound in which the coordinating functional group is a group containing COOH, COO − , or a salt of COOH; and   component (A-2) an aromatic compound in which the coordinating functional group is a group containing OH, O − , or a salt of OH.   
     
     
         5 . The fiber-treating agent of  claim 4 , wherein the component (A) is the component (A-1). 
     
     
         6 . The fiber-treating agent of  claim 1 , wherein the component (B) is an azo initiator. 
     
     
         7 . The fiber-treating agent of  claim 1 , wherein
 a pH of the fiber-treating agent containing the component (A) is 2.0 or more and less than 6.5, and   a content of the component (A) in an undissociated form in the fiber-treating agent is 0.1 mass % or more and 40 mass % or less.   
     
     
         8 . The fiber-treating agent of  claim 1 , wherein
 a pH of the fiber-treating agent containing the component (A) is 6.5 or more and less than 11.0, and   a content of the component (A) in an undissociated form in the fiber-treating agent is 1.0 mass % or more and 90 mass % or less.   
     
     
         9 . A fiber-treating agent kit, comprising
 a first composition containing
 component (A): an aromatic compound having one or more vinyl groups or vinylidene groups, and a coordinating functional group, and 
 component (C): water; and 
   a second composition containing
 component (B): a radical initiator, and 
 component (C): water. 
   
     
     
         10 . The fiber-treating agent of  claim 1 , which is a one-part type fiber-treating agent formed of a single composition comprising component (A), component (B), and component (C). 
     
     
         11 . The fiber-treating agent of  claim 1 , which is a multiple-part type fiber-treating agent formed of a plurality of compositions, a totality of which comprises component (A), component (B), and component (C).
