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.
