Abstract
Polyether esters are employed for the adhesive bonding of textiles since they are resistant to washing and dry cleaning. The polyether esters of the prior art have the disadvantage that they often exhibit poor adhesion with critical outer materials such as, for example, silk. By means of the polyether esters according to the invention, it is possible to bond sensitive textiles effectively at very low temperatures.
Claims7
A polyether ester for the adhesive bonding of textiles, obtained by reacting terephthalic acid, isophthalic acid, 1,4-butanediol and a polyethylene glycol, wherein the molar ratio of terephthalic acid to isophthalic acid is from 35 to 50 parts terephthalic acid:from 65 to 50 parts isophthalic acid, and the polyethylene glycol is employed in a proportion of from 10.5 to 25% by weight and with a molecular mass of from 0.4 to 6 kg/mol, based on the sum of all of the radicals present in the polyether ester.
