Modified regenerated collagen fibers, production method therefor, and headdress product including same

Abstract

Modified regenerated collagen fibers which have improved water resistance and heat resistance problematic in regenerated collagen fibers, impart heat shape memory ability, are excellent in stretchability (tenacity) and the feel of the surfaces, and have no coloring. The modified regenerated collagen fibers contain a component (A), which is vinylbenzoic acid or a salt thereof, or a polymerized product containing the component (A) as a constituent monomer in the regenerated collagen fibers.

1 . Modified regenerated collagen fibers, comprising at least one selected from the group consisting of
 component (A): vinylbenzoic acid or a salt thereof, and   a polymerized product including see component (A) as a constituent monomer.   
     
     
         2 . The modified regenerated collagen fibers of  claim 1 , further comprising
 component (C): a polyvalent metal, or a salt or complex thereof.   
     
     
         3 . The modified regenerated collagen fibers of  claim 2 , wherein the component (C) is aluminum, or a salt or complex thereof. 
     
     
         4 . A method for treating regenerated collagen fibers, the method:
 immersing regenerated collagen fibers in a fiber-treating agent, which is at least one selected from the group consisting of a one-part type fiber-treating agent formed of a single composition and a multiple-part type fiber-treating agent formed of a plurality of compositions, and which comprises in a total composition:   component (A): vinylbenzoic acid or a salt thereof; and   component (B): an azo polymerization initiator.   
     
     
         5 . The method of  claim 4 , wherein the fiber-treating agent in the immersing is a multiple-part type fiber-treating agent comprising a first part comprising the component (A) and a second part comprising the component (B); and
 the immersing comprises at least one selected from the group consisting of immersing the regenerated collagen fibers in the first part, and then immersing the regenerated collagen fibers treated with the first part in the second part, and immersing the regenerated collagen fibers in the second part, and then immersing the regenerated collagen fibers treated with the second part in the first part.   
     
     
         6 . The method of  claim 4 , wherein the regenerated collagen fibers comprise
 component (C): a polyvalent metal, or a salt or complex thereof.   
     
     
         7 . The method of  claim 6 , wherein the component (C) is aluminum, or a salt or complex thereof. 
     
     
         8 . A method for producing modified regenerated collagen fibers, the method comprising treating regenerated collagen fibers by the method of  claim 4 . 
     
     
         9 . A method for producing a headdress product, the method comprising treating regenerated collagen fibers by the method of  claim 4 . 
     
     
         10 . A headdress product comprising the modified regenerated collagen fibers of  claim 1 .
