摘要

使用聚乳酸（PLA）纤维制造非织造材料和线具有重要意义。对聚乳酸线的微观结构和特性进行了研究，并与聚酰胺线进行了比较。研究结果表明，聚乳酸线是一束直径为 14 ± 1 μm 的单丝，由结晶度较高（高达 60%）的聚乳酸制成，因此抗拉强度较高（90-95 兆帕）。聚乳酸丝的特点是在加热到玻璃化温度以上时会收缩达 8%。

Fibers and Filaments from Polylactic Acid: Production Features, Structure, and Physical–Mechanical Properties

The use of fibers from polylactic acid (PLA) to create nonwoven materials and threads is relevant. A study of the microstructure and properties of PLA threads was carried out, followed by comparison with polyamide ones. It has been established that PLA threads are bundles of monofilaments with a diameter of 14 ± 1 μm made of PLA with a high degree of crystallinity (up to 60%), which determines high tensile strength (90–95 MPa). PLA threads are characterized by shrinking up to 8% when heated above the glass transition temperature.
