What is PLA Fiber?
Polylactic acid (PLA) is an environmentally friendly, plant-derived thermoplastic. The fiber forming substance is a lactic acid polymer in which at least 85% by weight are lactic acid ester units derived from naturally occuring sugars (sugar beets and corn).Bico PLA with sheath/core structure has property of low melting point 130℃（sheath）and core melting point 160℃.
PLA is fully biodgradable and biocompatible which is also a thermalbond fiber used for hygiene and medical products.
The fiber is also useful as an eco- and people-friendly alternative to existing textile fibers for industrial and consumer apparel applications such as outdoor furniture, automotive interior fabrics, activewear, shoe linings, and disposable products like diapers and wipes, either at 100% or in blends with natural fibers such as cotton
