ABSTRACT:
The invention concerns a heat-sealing adhesive on the basis of copolyamides for the coating of fabrics, and especially of linings for outerwear. The invention consists of the fact that this heat-sealing adhesive contains from 0.3 to 15% by weight, preferably 0.7 to 12% by weight, of behenic acid. Thereby a substantially and unexpectedly increased adhesion strength of the adhesive is attained, so that for the same adhesive strength a smaller amount of the heat-sealing adhesive is required. This improves the comfort provided by the article of clothing when being worn.
The invention also concerns a process for the manufacture of this heat-sealing adhesive as well as its use for the coating of lining fabrics.
