METHOD FOR PREVENTING THE SHRINKAGE OF WOOLEN OR WOOL BLEND FABRICS

摘要

Method for preventing the shrinkage of woolen or wool blend fabrics during water washing treatment, comprising the initial impregnation of the fabric of interest with a reducing product ( compound A) and after suitable mechanical and drying treatment, the subsequent contact of the resulting fabric with a blend of products comprising at least one compound of each of the following groups: vinylic and acrylic resins, ethylene vinyl acetates, blocked or non-blocked isocyanates, blocked or non-blocked in water and solvents polyisocyanates ( compound B); blocked or non-blocked in water and solvents polyisocyanates (compound C); silicon emulsions, macro-emulsions, cationic fabric conditioners ( compound D).
