Breathble pla spunbond nonwoven

At present, polypropylene (PP) is still the main material used in non-woven fabrics, and its degradation properties do not meet the requirements of environmental protection and sustainable development. Promoting the application of biodegradable materials in the field of non-woven fabrics will be the trend. Various non-woven fabrics made from polylactic acid are biodegradable, and some blend polylactic acid with other natural fibers or synthetic fibers to make the final product biodegradable.

Polylactic acid (PLA) is a new type of biodegradable material made from starch derived from renewable plant resources such as corn. Starch raw materials are saccharified to obtain glucose, which is then fermented with certain strains to produce high-purity lactic acid. Then, a certain molecular weight of polylactic acid is synthesized through chemical synthesis methods. It has good biodegradability and can be completely degraded by microorganisms in nature after use, ultimately generating carbon dioxide and water without polluting the environment.

This is very beneficial for protecting the environment and is recognized as an environmentally friendly material. Caring for the Earth, we have a responsibility. According to news reports, global carbon dioxide emissions are expected to rise to 60 ℃ by 2030. The treatment method for ordinary plastics is still incineration and cremation, causing a large amount of greenhouse gases to be released into the air. Polylactic acid plastics, on the other hand, are buried in the soil for degradation, producing carbon dioxide that directly enters the soil organic matter or is absorbed by plants, without being discharged into the air or causing a greenhouse effect.

The characteristics of PLA polylactic acid non-woven fabric

Moisture proof, breathable, flexible, lightweight, non combustible, easy to decompose, non-toxic and non irritating, rich in color, recyclable.

Application example of PLA non-woven fabric

Taking the application of non-woven fabrics in the medical and health fields as an example, PLA non-woven fabrics not only fully meet the safety and usability requirements of disposable protective equipment, but also endow the product with new green and environmentally friendly characteristics. After use, it can be completely biodegraded under composting conditions within a few months, not only without causing any burden to the environment, but also participating in natural circulation.

In addition, polylactic acid membrane cloth is a new biological based material with soft hand feel, strong adsorption, moisture retention, breathability and bacteriostasis. It is a pure, safe, healthy and close to the skin high-quality material. It has many biological characteristics that other substrates cannot match, and is an ideal substrate for high-quality facial mask.
