摘要:
CELLULOSIC TEXTILES ARE TREATED WITH AN ESTER WHICH CONTAINS, ON AVERAGE, AT LEAST TWO MERCAPTAN GROUPS PER MOLECULE, AND WITH AN AMINOPLAST WHICH IS FREE FROM ETHYLENIC UNSATURATION, AND THE AMINOPLAST IS CURED. THE TREATED TEXTILES HAVE ENHANCED DIMENSIONAL STABILITY, RESISTANCE OF CREASING, AND MAY HAVE PERMANENT CREASES IMPARTED, WHILST HAVING A FULLER, SOFTER HANDLE AND INCREASED TEAR STRENGTH COMPARED TO CELLULOSIC TEXTILES TREATED WITH THE AMINOPLAST ALONE. TYPICALLY, THE ESTER IS PREPARED BY THE REACTION OF (A) A COMPOUND CONTAINING AT LEAST TWO CARBOXYLIC ACID GROUPS, (B) A COMPOUND CONTAINING AT LEAST TWO ALCOHOLIC HYDROXYL GROUPS AND, OPTIONALLY, (C) A COMPOUND CONTAINING NOT MORE THAN ONE CARBOXYLIC ACID GROUP OR ALCOHOLIC HYDROXYL GROUP, ESPECIALLY A MONOMERCAPTOMONOCARBOXYLIC ACID OR A MONOMERCAPTOMONOHYDRIC ALCOHOL.
