PLA (Polylactic Acid) Nonwoven Fabric
Polylactic acid non woven fabric, also called PLA, is a type of 100%biodegradable nonwoven.
PLA nonwovens are made from PLA resin or fibers which are producedfrom bioplastics derived from natural sources like crude corn, starch,and sugar.
Strong yet soft like traditional nonwoven PLA fibers are very durabledue to their 95% crimp resilience which is better than any otherchemical fiber on the market.
The features of PLA non-woven:
● Degradable
● Environmental protection and no pollution
● Soft and skin-friendly
● The surface of the cloth is smooth without crumbs, and the uniformity is good
● Good ventilation performance
● Good water absorption performance

Characteristics f PLA nonwoven Fabrics
Corn fiber (PLA), also known as: polylactic acid fiber; has excellent drapability, smoothness, moisture absorption and breathability, natural antibacterial and weak acidity that reassures the skin, good heat resistance and UV resistance, the fiber It does not use petroleum and other chemical raw materials at all, and its waste is under the action of microorganisms in soil and seawater.
It can be decomposed into and water, and will not pollute the earth’s environment. Since the initial raw material of the fiber is starch, its regeneration cycle is short, about one to two years, and its content in the atmosphere can be reduced by plant photosynthesis. Burning PLA fiber, almost none, its heat of combustion is about one-third that of polyethylene and polypropylene.
PLA fiber uses natural and renewable plant resources as raw materials, which reduces the dependence on traditional petroleum resources and meets the requirements of sustainable development of the international community. The characteristics of biodegradation, compared with conventional fibrous materials,
Thermally bonded and needle punched nonwovens produced using PLA are more versatile. Household diapers, sanitary napkins, polylactic acid fiber quilts, etc. have been developed without adding any ingredients. The material is naturally antibacterial and anti-mite.
