THERMAL ADHESIVE CO-POLYESTER WITH EXCELLENT BIODEGRADABILITY, THERMAL ADHESION, HARDNESS AND TOUGHNESS, A PREPARING METHOD THEREOF, AND A BINDER FIBER CONTAINING THE SAME

摘要

PURPOSE: Thermal adhesive co-polyester is provided to have high glass transition temperature and excellent adhesion when thermally bonding fibers and to have excellent rigidity and toughness of a surface of non-woven fabric.;CONSTITUTION: Thermal adhesive co-polyester is manufactured by reacting dicarboxylic acid components and diol components. The dicarboxylic acid component is 70-95 mol% of aromatic dicarboxylic acid and/or aromatic dicarboxylic acid ester formable derivative, and 5-30 mol% of aliphatic dicarboxylic acid and/or aliphatic dicarboxylic ester formable derivative. The diol component consists of 80-99 mol% of diol of linear-structure, and 1-20 mol% of diol of symmetric cyclic structure.;COPYRIGHT KIPO 2013
