THERMAL ADHESIVE BIODEGRADABLE CO-POLYESTER CONTAINING DICARBOXYLIC ACID, AND DIOL COMPONENTS HAVING EXCELLENT ADHESION, AND A BINDER FIBER THEREOF

摘要

PURPOSE: A thermal adhesive biodegradable co-polyester is provided to have excellent adhesion, touch-feeling after attachment, in case of manufacturing non-woven fabric, and to have environment-friendly properties because of high biodegradability.;CONSTITUTION: Thermal adhesive biodegradable co-polyester comprises a dicarboxylic acid component, and a diol component. The dicarboxylic component consists of: 90-40 mol% of terephthalic acid, terephthalic acid ester formable derivative, or a mixture of terephthalic acid and terephthalic acid ester formable derivative; 5-30 mol% of isophthalic acid, isophthalic acid ester formable derivative, or a mixture of isophthalic acid and an isophthalic acid ester formable derivative; and 5-30 mol% of glutaric acid, glutaric acid ester formable derivative, or a mixture of glutaric acid and a glutaric acid ester formable derivative. The diol component consists of 95-80 mol% of ethylene glycol, and 5-20 mol% of diethylene glycol.;COPYRIGHT KIPO 2012
