Verfahren zur Heißversiegelung von textilen Flächengebilden

摘要

Copolymers of ethylene and vinyl acetate are prepared which contain vinyl acetate and ethylene in a molar ratio of 1:4 to 1:50 and are then saponified to a degree of hydrolysis of 50-100%. Forms specified are powders, threads, fibres, pulverulent grains, woven fabrics and fleeces and are used for heat-sealing textile sheet structures.
