Polylactic Acid (PLA) Fibre

摘要

Polylactic acid (PLA) fiber is a new type of bio-degradable and thermoplastic fibre. It is aliphatic polyester derived from renewable resources, such as corn starch or sugarcanes. Polylactic acid fibre and its products are biodegradable in nature and under certain conditions it can be decomposed into carbon dioxide and water, thus do not produce any pollution to the environment. PLA is soft, smooth, and light in texture and good heat resistant similar to silk for its gloss. It has many potential uses in non-woven, spinning and as filler material. It is easily converted into a variety of fiber forms by using conventional melt-spinning processes. This fiber does not use any petro-based chemicals. So it can solve the environmental problem, and it also lowers the growing shortage of the energy crisis.
