The corn fiber (PLA fiber) with a specification of 50D/48F has properties such as anti-mite, antibacterial, anti-mildew, and anti-static. It is very suitable for the weaving of underwear and panties. Moreover, when you want to discard and replace it after wearing it for a period of time, it will not cause secondary pollution to the environment, because it can be degraded and disappear through methods such as being buried in the soil and then become part of the environment again.
PLA fiber is made from lactic acid derived from starch. It belongs to the type that completes the natural cycle and is a biodegradable fiber. This fiber does not use chemical raw materials such as petroleum at all. Under the action of microorganisms in the soil and seawater, its waste can be decomposed into carbon dioxide and water, without polluting the earth's environment. Since the initial raw material of this fiber is starch, its regeneration cycle is short, approximately one to two years. The carbon dioxide it generates can be reduced in the atmosphere through the photosynthesis of plants. When burning PLA fiber, there is almost no nitrogen monoxide, and its combustion heat is about one-third of that of polyethylene and polypropylene.
Uses of corn fiber:
Polylactic acid fiber is a lactic acid polymer synthesized from lactic acid contained in the human body, and it is safe for the human body. Through testing, circular knitted fabric made of corn fiber does not irritate the skin, is beneficial to human health, and provides a sense of comfort.
Polylactic acid fiber has superior properties, including excellent drapability, smoothness, moisture absorption and breathability, natural antibacterial properties, a weakly acidic property that makes the skin feel at ease, good heat resistance, anti-ultraviolet function, and it is lustrous and elastic. The drapability of PLA fiber fabric, the smooth feeling close to the skin, as well as the softness of the fabric, hydrophilicity, and color luster are all well reflected, giving corn fiber significant development advantages in the development of close-fitting underwear, sportswear, etc. In 2004, three well-known domestic brands, such as Shanghai Duocai, Qingdao Nuanbeier, and Shanghai Kelefei, had already launched thermal underwear made of corn fiber.
Blending corn fiber with natural fibers such as cotton and wool to make new textile products, these products have good shape retention, relatively good gloss, a silk-like hand feel, good moisture absorption and quick-drying effects, combining the effects of being stiff, having good elasticity, and being lustrous.
In addition to being used in clothing, it can also be widely applied in civil engineering, buildings, agriculture and forestry, aquaculture, the paper industry, healthcare, and household items. PLA fiber can also be used to produce biodegradable packaging materials.
Renewable raw materials:
PLA fiber uses natural and renewable plant resources as raw materials, reducing the dependence on traditional petroleum resources and meeting the requirements of sustainable development in the international community. It combines the advantages of synthetic fibers and natural fibers, and at the same time has the characteristics of a complete natural cycle and biodegradability. Compared with conventional fiber materials, corn fiber also has many unique properties, so it has received extensive attention from the international textile industry.
Environmental protection:
With the enhancement of human awareness of protecting the earth, awareness of energy depletion, safety awareness, and clothing hygiene awareness, as well as the large-scale industrial production of PLA resin and the continuous expansion of the application fields of corn fiber, it has been regarded by many as an "environmental cycle material in the 21st century" and is an ecological fiber with great development potential.
