Sewn products and method for preventing seam puckering on sewn products

Abstract

Seam puckering on a sewn product made of cellulosic fibers, synthetic fibers and/or animal fibers can be prevented from occurring by simply applying a (meth)acrylate resin finish and/or a polyester resin finish to the seams on the sewn product, then hot pressing the seam. The addition of an acidic catalyst, a polyether compound, or a combination of a cellulose-reactive resin finish with an acidic catalyst to the (meth)acrylate finish and/or polyester resin finish provides a better seam pucker preventing effect on cellulosic fibers than do existing cellulose-reactive resin finishes.

1 . A method for preventing seam puckering on a sewn product, comprising the steps of: 
 applying a (meth)acrylate resin finish or a polyester resin finish or both to a seam on the sewn product, then    hot pressing the seam.    
   
   
       2 . The method of  claim 1 , wherein a mixture of the (meth)acrylate resin finish and the polyester resin finish is applied.  
   
   
       3 . The method of  claim 1 , wherein the resin finish additionally includes at least one substance selected from the group consisting of acidic catalysts, polyether compounds, cellulose-reactive resin finishes, fluorescent pigments and other pigments.  
   
   
       4 . The method of  claim 1 , wherein hot pressing is carried out with a hot pressing machine or by ironing.  
   
   
       5 . A sewn product obtained by the method of  claim 1.
