Polylactic acid (PLA) is a new type of biodegradable material, mainly made from renewable plant resources (such as corn) as raw materials for starch production. It has good biodegradability and biocompatibility. Packaging, fiber, and medical use are its three major hot application directions. As a thermoplastic fiber-grade resin, fiber-grade PLA is in the form of particles, and is extruded into mechanically stretched short fibers using conventional fiber spinning and stretching equipment. It has excellent coloring, mechanical and physical properties, and can adapt to various printing methods, and is used in various occasions.
PLA non-woven fabric is a new type of biobased material with good uniformity, excellent drape, smoothness, breathability, natural antibacterial performance, good skin-friendly properties, and UV resistance. PLA non-woven fabric is recognized as an environmentally friendly material with good biodegradability. It can degrade and be completely degraded into carbon dioxide and water by microorganisms in nature under specific conditions. It will not pollute our environment.
PLA non-woven fabric not only meets the safety and convenience requirements of disposable protective products, but also adds new environmental characteristics to the products. Under composting conditions, it can completely biodegrade within a few months. It does not burden the environment, but integrates into the natural cycle.
The advantages of PLA non-woven fabric are reflected in the fact that when polylactic acid (PLA) is incinerated, its combustion heat value is the same as that of incinerated paper, which is half of that of incinerated traditional plastics (such as polyethylene). Moreover, incineration of polylactic acid will absolutely not release toxic gases such as nitrides and sulfides. The human body also contains lactate in monomeric form, which indicates the safety of this decomposable product.
PLA non-woven fabric is moisture-proof, breathable, flexible, lightweight, non-combustible, compostable, non-toxic, non-irritating, bright in color, and recyclable. In addition, PLA non-woven fabric is a pure, safe, healthy, and skin-friendly high-quality material. It has many biological characteristics that cannot be compared with other materials. It is also an ideal base material for making high-quality masks. PLA non-woven fabric has a wide range of uses, mainly including packaging bags, shopping bags, home decoration, daily necessities, clothing linings, aviation fabrics, environmental protection filters, sanitary materials, and other diversified fabrics. It can be used for disinfecting wipes, masks, diapers, civilian wet wipes, wet facial wipes, beauty products, sanitary pads, etc.
