WATER-REPELLENT FINISHING OF FABRIC CONTAINING SOLVENT-SPUN CELLULOSIC FIBER

摘要

PROBLEM TO BE SOLVED: To impart water-repellent performance with good washing durability to fabric by treating a solvent-spun cellulosic fiber-containing fabric with a cellulosic crosslinking resin and subjecting the fabric to water-repellent finishing by using both of a water repellent and a crosslinking agent. ;SOLUTION: A cellulose crosslinked resin such as glyoxal-based resin in an amount of 0.5-20 wt.% based on fiber weight is applied to solvent spinning method-based cellulosic fiber-containing fabric and crosslinking reaction treatment is applied to the fabric and then, an organic fluorine-based water repellent in an amount of 2-20 wt.% based on fiber weight and a blocked isocyanate-based crosslinking agent in an amount of 0.5-3 wt.% based on fiber weight are applied to fiber so that a weight ratio of the water repellent to the crosslinking agent used is (4:1) to (6:1) and the treated fabric is dried at 80-160°C and then, subjected to heat treatment at 130-220°C which is not lower than crosslinking reaction temperature for 0.5-5 min.;COPYRIGHT: (C)1999,JPO
