PLAis one of the biodegradable materials that have received the most attention from domestic and foreign research. Medical, packaging and fiber are three popular application fields. PLA uses natural lactic acid as the main raw material and has good biodegradability and biocompatibility. Its life cycle load on the environment is significantly lower than that of petroleum-based materials. It is considered to be the most promising green packaging material.
With the improvement of people’s awareness of environmental protection, the use of recycled materials in nonwovens has become a new trend.
PLA fiberis recommended by many experts as a new material for environmental circulation in the 21st century because of its reproducibility and biodegradable. It is a kind of ecological fiber with great development potential.
Corn fiber (PLA), also known as polylactic acid fiber, has excellent drape, smoothness, moisture absorption and breathability, natural antibacterial and weak acidity that makes the skin reassuring, good heat resistance and UV resistance, the fiber Chemical raw materials such as petroleum are not used at all, and its waste can be decomposed into carbon dioxide and water under the action of microorganisms in the soil and seawater, and will not pollute the global environment. Since the initial raw material of the fiber is starch, its regeneration cycle is short, about one to two years, and the carbon dioxide produced by it can be reduced in the atmosphere by plant photosynthesis. When PLA is buring, there is almost no nitric oxide, and its combustion heat is about one-third of polyethylene and polypropylene.
PLA fiber uses natural and reproducibility plant resources as raw materials, reduces dependence on traditional petroleum resources, and meets the requirements of sustainable development in the international society. It has both the advantages of synthetic fibers and natural fibers, and at the same time has a completely natural cycle and energy. Compared with conventional fiber materials, corn fiber has many unique properties due to the characteristics of biodegradation, so it has received extensive attention from the international textile industry.
In addition to being used as clothing, it can also be widely used in civil engineering, buildings, agriculture and forestry, aquaculture, paper industry, health and medical treatment and household articles. PLA fiber can also be used to produce biodegradable packaging materials.
The maximum width is 3.2m, and the weight range is 20-100g/m2. The softness and hardness can be customized according to the actual requirements of the customer. There is no limitation on the quantity of the white, the minimum order quantity of the black PLA fiber is 5 tons, and the minimum order quantity of colorful PLA fiber is 5 tons(Customers need to provide color card for color).
Environmental protection products: food grade material, environmental protection and health, no fluorescent agent, no azo, formaldehyde, pentachlorophenol, eight heavy metals (lead, cadmium, barium, chromium, antimony, selenium, arsenic, mercury);
Product performance is superior and stable: excellent permeability, multi-purpose brewing and decoction type, multi-functional bag;
The material is thick and resistant to soaking and boiling, and can be used repeatedly; it does not damage the environment and can be composted. It can be buried in the soil. Under a certain temperature, humidity and microbial action, it can be completely degraded in about a year, and finally decomposed into carbon dioxide and water.
Physical strength: strong tensile force, high abrasion resistance, good moisture conductivity and air permeability, clean and hygienic.
