To polylactic acid(PLA) filament yarn and cotton yarn as raw material,and make full use of the PLA on wet performance and cotton fiber moisture absorption.Case minimize the lateral density of the fabric,the longitudinal density,thickness,and weight differences,through the a reasonable fiber content design,prototype seven different content of the PLA / cotton knit fabric.After wicking test,the experiment showed that when the content of PLA / cotton 35/65 to 65/35,the fabric guide good wet performance,comfortable to wear and provide the basis for the actual production of water vapor transmission rate.

21世纪,全球的环境污染日趋严重,资源的日益短缺,使得绿色环保的可再生材料的研究成为了科学研究的重要方向。本文简单介绍了聚乳酸纤维的发展背景及现状,阐述了聚乳酸纤维的制备、性能及应用,从聚乳酸纤维的结构性能及应用领域来探讨聚乳酸纤维的发展趋势,从而更好的认识了解聚乳酸纤维,以便使其更好的应用于改善人类生活环境和提高生活质量。
