POLYURETHANES CONTAINING ISOCYANATE GROUPS ARE REACTED WITH GLYCIDOL TO PREPARE GLYCIDOL-MODIFIED POLYURETHANES USEFUL FOR APPLICATION TO TEXTILE MATERIALS TO IMPROVE THEIR PROPERTIES, E.G., TO IMPART SHRINK RESISTANCE. TYPICAL EXAMPLE: A POLYETHER POLYURETHANE CONTAINING FREE NCO GROUPS IS REACTED WITH GLYCIDOL TO YIELD A GLYCIDOL-MODIFIED POLYMER WHICH IS FORMED INTO AN EMULSION AND APPLIED TO A TEXTILE MATERIAL. THE TREATED TEXTILE MAY BE DIRECTLY CURED OR THE CURING OPERATION MAY BE DELAYED UNTIL THE FABRIC IS MANUFACTURED INTO A FINISHED GARMENT. |
