PLA-Polylacticacid-One of the safest materials ever
Resource depletion: While human beings enjoy the convenience brought by polymer materials (plastics and chemical fiber) to their daily life, oil resources are increasingly exhausted, "white pollution" is aggravated, and the "microplastics" of chemical fiber are always threatening human survival.
Environmental pollution: The global waste of polymer materials amounts to 260 million tons every year. Our cities and rural areas are surrounded by white garbage, and the situation is very serious.
Burying: causing a large amount of land waste, toxic substances released to pollute groundwater, and breaking the ecological balance.
Incineration: causing serious water, air and soil pollution, resulting in ozone layer destruction, acid rain formation, carcinogenesis, etc.
We: In order to solve the ecological problems caused by chemical fiber, biodegradable and recyclable bio-based environmental protection materials came into being.
Polylactic acid fiber
Poly (lactic acid) is a kind of polymer material obtained by special polymerization reaction with starch-rich agricultural crops (corn, potato, cassava, etc.) as raw materials. It is a completely biodegradable green environmental protection material.
Performance 1 - biodegradable
Under composting conditions (temperature 58 ℃, humidity 98% and microbial conditions) for 3-6 months, polylactic acid product waste can be completely decomposed into carbon dioxide and water in natural environment for 1-2 years, which has very good environmental protection effect. In the incineration process of polylactic acid materials, only the oxidation pond and water are produced, and no toxic gas and dust particles are produced. In the process of natural degradation or incineration and landfill, there will be no harm to the human environment.
Performance 2 - Antibacterial and anti-mite
The surface of polylactic acid material is weakly acidic, which will inhibit the growth of microorganisms, and will not provide food sources for microorganisms. Therefore, it has excellent natural anti-mite and anti-mite properties. After testing and verification by authoritative testing institutions, 15% polylactic acid has extremely strong anti-mite and anti-bacterial effects. The anti-bacterial and anti-mite properties of polylactic acid materials are durable and will not weaken with the increase of washing times.
Performance 3 - Safety
Because the degradation products of polylactic acid can penetrate into the human body and participate in metabolism, the final products are carbon dioxide and water, so it will not have toxic and side effects on the human body and is very safe to use. Poly (lactic acid) has been used in many fields such as medicine and pharmacy, such as surgical sutures (introduced in 1975), drug delivery systems, bone nails, tissue scaffolds, and medical sanitary materials such as bandages and gauzes.
Performance 4 -- flame retardant and less smoke
Compared with traditional materials, polylactic acid has the advantages of flame retardant (the limiting oxygen index is close to the requirements of 28% - 30% of the national standard for flame retardant fiber), low smoke emission and no black smoke even when burning, so it is particularly suitable for use as carpet, curtain, wall cloth and other household decoration products and decorative materials in public places.
Product development direction
According to the main properties of polylactic acid material, such as antibacterial, anti-mite, biodegradable and flame retardant, the preliminary research and development direction of the product is determined:
-PLA filled products: quilts and pillows (civilian and military), pillow and dolls, etc
-Healthy home textile products: bedclothes, carpets, curtains, sofas, etc
-Disposable products: disposable masks, facial mask, cotton napkins, diapers, gloves, socks, etc
-Women's sanitary products: polylactic acid sanitary cotton, underwear, etc
-Clothing: polylactic acid home clothes, shirts, underwear, pajamas, bathing caps, etc
-Medical: surgical clothes, hand washing clothes, nursing pads, medical dressings, surgical sutures, scar stickers, etc
-Car interior decoration, seat cover
