生物可降解聚乳酸纤维的发展现状及其改性研究

Development and Modification of Polylactic Acid Fibers

介绍了聚乳酸纤维国内外的研发现状和产能,并对比了聚乳酸纤维与其它纤维的性能差异。针对聚乳酸纤维耐热性差、柔韧性差以及功能化率低等特点,系统介绍了现阶段国内外研究人员通过共混、表面改性等不同方法对聚乳酸纤维的改性研究;探讨不同改性方法目前的研究现状以及优缺点;阐明聚乳酸纤维的未来研究方向应朝着差别化、功能化、高值化方向发展。

This paper reviews the current research status and manufacturing capacity of polylactic acid(PLA)fibers at domestic and foreign countries.Besides,the performance differences between PLA fibers and other fibers are compared.In view of poor heat resistance,poor flexibility and low functionalization rate of PLA fibers,we review recent progress and advances that have been made on the modification of PLA fibers by different methods such as blending modification and surface modification,and introduces the advantages and disadvantages of different modification methods.It is pointed out that PLA fibers should be developed towards differentiation,functionalization and high value.
