Abstract

Crosslinking reaction was carried out between DMDHEU antral cellulose by using pad-dry-cure(PDC)method in the presence of mixed catalysts such as aluminum sulfate/glycolic acid, aluminum sulfate/tartaric acid, antral aluminum sulfate/citric acid. Effects of catalyst system and total concentration, mixture ratio of catalyst, and curing condition were investigated. And also durability test to home laundering, SEM analysis, moisture regain measurement, and FT-lR spectroscopic analysis were done. Optimum finishing conditions obtained were 16$0^{\circ}C$/2.5~3 minutes curing and 2.5% aluminum sulfate/0.5% acid of mixture ratio for all three mixed catalyst systems. The fabric samples treated with miked catalysts at optimum conditions showed better balance of Dp/performance properties than those of treated by conventional single catalyst. Regardless of catalyst systems, durability to home laundering of treated samples showed similar results. SEM analysis showed no big difference in resin distribution and penetration level between catalysts. And moisture regain was decreased after crosslinking reaction and showed the decrease as catalyst concentration was increased. Mixed catalysts imparted bettor balance of Dp/performance properties and this synergistic effect seemed to attribute to the complex formation.
