Fiber processing agent and fiber processed with the fiber processing agent

Abstract

The present invention provides a fiber processing agent used for processing a surface of a fiber, and the fiber processing agent contains a soluble eggshell membrane and a reactive organic compound having a reactive group. With the fiber processed with the fiber processing agent having the composition as described above, even when the fiber is used for a long period of time, the eggshell membrane is not removed therefrom and the properties provided by the eggshell membrane can be maintained, so that the fiber has excellent durability and can continuously provide the moisture retention, water-absorbing property, moisture-absorbing property, antistatic property, and wound-treating property.

1 . A fiber processing agent used for processing a surface of a fiber, comprising: 
 a soluble eggshell membrane; and a reactive organic compound having a reactive group.    
   
   
       2 . The fiber processing agent according to  claim 1 , 
 wherein the reactive organic compound contains one or more of (component 1) a hydrophilic compound having a polymerizable vinyl group in the molecule, (component 2) a monomer containing any of a hydroxyl group, a carboxylic group, an amino group, a sulfonic group, and a phosphate group, (component 3) a hydrophilic compound having an epoxy group, and (component 4) a compound having an aziridine group.    
   
   
       3 . The fiber processing agent according to  claim 1  or  claim 2 , 
 wherein a content of the soluble eggshell membrane relative to the total weight of the fiber processing agent is in the range from 0.1 to 10% by weight; and    a content of the reactive organic compound is in the range from 1 to 20% by weight.    
   
   
       4 . A fiber processed with the fiber processing agent according to any of  claims 1  to  3 .  
   
   
       5 . A fiber processing agent used for processing a surface of a fiber comprising: 
 a soluble eggshell membrane; and an organic compound having adhesiveness.    
   
   
       6 . The fiber processing agent according to  claim 5 , 
 wherein the organic compound having adhesiveness is a reactive organic compound having a reactive group.    
   
   
       7 . A fiber processing agent according to  claim 6 , 
 wherein the reactive organic component contains at least one of (component 1) a hydrophilic compound having a polymerizable vinyl group in the molecule, (component 2) a monomer containing any of a hydroxyl group, a carboxylic group, an amino group, a sulfonic group, and a phosphate group, (component 3) a hydrophilic compound having an epoxy group, (component 4) a compound having an aziridine group, and (component 5) a compound containing an isocyanate group or a precursor thereof.    
   
   
       8 . The fiber processing agent according to  claim 5 , 
 wherein the organic compound having adhesiveness is a lipophilic compound such as wax and silicone and/or high molecular compound containing a group such as ether, acryl, urethane, amide, and ester.    
   
   
       9 . A fiber processed with the fiber processing agent according to any of  claims 5  to  8 .
