Biodegradable polylactic acid nonwoven fabric (PLA)

Mar.2022 | Company News

As polylactic acid is a bio renewable raw material, its manufacturing process produces less greenhouse gases than other polymers.
Therefore, polylactic acid is a new environmental protection material, which has no pollution to the environment.
As polylactic acid is a bio renewable raw material, its manufacturing process produces less greenhouse gases than other polymers.
Therefore, polylactic acid is a new environmental protection material, which has no pollution to the environment. Polylactic acid not only has the characteristics of good strength, chemical inertia and easy processing, but also has excellent biocompatibility and biodegradability.
Polylactic acid is degraded by hydrolysis. The low polymer produced by hydrolysis will eventually produce water and carbon dioxide under the metabolic action of microorganisms, which will not cause secondary pollution to the environment,
Polylactic acid is a light yellow or transparent polymer. It is a thermoplastic polymer material with properties similar to polystyrene (PS) and polyester (PET).
Conventional melt spinning equipment (such as spunbonded and melt blown production system) can be used to produce polylactic acid nonwovens.

Characteristics of polylactic acid Nonwovens
(1) In addition to the decomposition of polylactic acid waste in the natural environment, there is no toxic gas produced by incineration. In addition, it can also be composted, which has no pollution to the environment.
In addition, the carbon dioxide produced by its decomposition can be reused through plant photosynthesis to produce starch. It is a kind of pollution-free natural recycling material.

(2) In addition to the decomposition of polylactic acid waste in the natural environment, there is no toxic gas when it is burned. In addition, it can also be used as compost, which is completely harmless to the environment.

(3) Polylactic acid nonwovens have dyeability and good mechanical and processing properties. They can process all kinds of products in the city and have a wide range of applications.

Application of lactic acid Nonwovens
Polylactic acid nonwovens are mainly used in agriculture, horticulture and other aspects. They can be used as cloth for seed cultivation, seedling raising, frost prevention and weeding.
Widely used in terms of medical and health care, it can be used as surgical clothes, surgical covering cloth, mask, etc; It can also be used as diapers, fabrics of women's sanitary napkins and other physiological daily necessities;
In terms of daily necessities, it can be used as wiping cloth, kitchen water filter bag, slag filter bag or other packaging materials:
Using polylactic acid nonwovens to replace some non decomposable general plastic products plays an important role in reducing environmental pollution
