Due to the development of microbial technology, there are several types of biodegradable plastics in the world, among which polylactic acid is becoming more and more popular. Since polylactic acid plants do not consume natural resources, nonwoven manufacturers are increasingly interested in developing new products using this raw material. Various nonwovens (degradable nonwovens wholesale) are made of polylactic acid, which is biodegradable, and some blend polylactic acid with other natural fibers or rayon to make the final product biodegradable.Therefore, more and more customer focus on the PLA non woven machine.

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,
Corn fiber also has many unique properties, so it has received extensive attention from the international textile industry.
It has a soft feel, strong adsorption, moisture, breathability and antibacterial properties. It is a pure, safe, healthy and high-quality material close to the skin. It has many biological properties unmatched by other substrates. Ideal base material for high-quality face masks. PLA and its PLA fibers have natural antibacterial, anti-mite and PH values near the skin, known as people's second skin. Polylactic acid can support the normal growth of skin fibroblasts and is used as a cell culture material in skin tissue engineering in the medical field.
PLA can be implanted into the body and absorbed by the body. It has been used in the medical field for nearly 30 years. PLA fibers are used in mask substrates to separate some free small molecules. Small molecules have strong penetrating power. Combined with the lactic acid substance of the skin, it can not only inhibit bacteria, but also improve the absorption capacity of nutrient solution and enhance the growth vitality of facial skin. At the same time, the polylactic acid film cloth has good water absorption properties, can store more essence, and has strong adsorption properties, which can better absorb oil and remove impurities, so that the facial skin can achieve deeper cleanliness. The porous structure of the polylactic acid film allows air and moisture to pass through, fully retaining the active factors in the essence, and has a good moisturizing effect.
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.
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
