摘　　要：为了探讨聚乙烯醇浆料的环保性能,介绍了环保型纺织浆料的判别原则,分析了PVA浆料的毒性、生物降解性和对环境的影响,阐述了PVA浆料的生物降解机理和PVA降解酶难以商业化的原因。指出:PVA浆料的生物降解性较差,可以通过对PVA降解菌进行驯化这一途径,提高PVA的生物降解性。To discuss environmental protection of polyvinyl alcohol size mixture, estimating principle of environmental protection size mixture was introduced, and toxicity, biological degradability and influences on environment of PVA size mixture were analyzed. Biological degradability mechanism and PVA degradability enzyme problem were discussed. The result shows that PVA has worse biological degradability, it can be enhanced by planting degradability enzyme.
