WATER SOLUBLE POLYESTER COMPOSITE FOR IMPROVED SPINNABILITY, AND PREPARING THEREOF

摘要

PURPOSE: A water-soluble polyester group composition is provided to have the water-soluble polyester group composition which reveals the water solubility without having a separate component which includes 1,4- cyclohexanedimethanol or amine group etc.; in which the weight deduction process is easy and a weight loss rate is high. CONSTITUTION: A water-soluble polyester group composition which has improved radioactivity is comprised by adding more carbodiimine group resin in the water-soluble polyester group composition; and the water-soluble polyester group composition is formed by polymerizing an acid which includes terephthalic acid, isophthalic acid, dimethyl 5-sodiosulfo isophthalate; and a diol which includes ethylene glycol, diethylene glycol, polyethylene glycol. A bis-β-hydroxyethylterephthalate is additionally included in the polymerization. The acid and the diol are polymerized as a ratio of 1:1 - 1:10.
