Synthesis and Property of Biodegradable Watersoluble Polyurethane Size Mixture
摘要
Abstract
Sizing property of watersoluble polyurethane size mixture was studied. One kind of watersoluble polyure-thane textile size mixture was compounded by polyester glycol, polyether glycol, isophorone diisocyanate and dimethylol propionic acid. Size mixture structure was analyzed by infrared spectrometer. The sizing,size film property and biode-gradability are studied. The result shows that viscosity and its thermal stability of watersoluble polyurethane size mixture were better. Adhesion of the sizing to cotton fiber is better. The moisture absorption of sizing film is lower and its alkali-soluble is better. Reviscosity after moisture absorption can be prevented effectively, the size can be desized easily. BOD5/COD value of polyurethane size mixture is larger than 0. 45 ,the size mixture can be degraded easily. It is considered that PVA can be replaced partial or completely by the polyurethane size mixture.关键词
