China’s first poly (lactic acid) environmental protection textile comes out like human skin

it is understood that under the leadership of Ren Jie, professor and doctoral supervisor of Tongji University, Shanghai tongjieliang biomaterials Co., Ltd. and Shanghai green plastic Biotechnology Co., Ltd. have successfully produced fiber and its series of underwear and environmental protection bags with polylactic acid as raw material in cooperation with relevant universities, scientific research institutions and textile enterprises in Shanghai and Zhejiang, The industrial manufacturing technology of PLA and its textiles with independent intellectual property rights in China has been put into trial use in Shanghai World Expo and is favored by tourists

what is polylactic acid environmental textiles

biomass material polylactic acid is made from cassava, sweet sorghum and other non grain crops as well as agricultural wastes such as straw and rice straw through biological fermentation and then through polymer polymerization. Polylactic acid fiber is a kind of biological synthetic fiber made by regular spinning process of polylactic acid resin. 1ts physical properties are close to nylon and polyester, and its air permeability and handle are better than polyester. 1t is not easy to generate static electricity, and has good biocompatibility and comfort. 1t can be made into multifilament, monofilament, staple fiber, knitted fabric, nonwovens, etc. it can be used as underwear, baby diaper, female sanitary products, and so on Jackets and socks, as well as medical textiles such as surgical clothing, protective clothing, surgical coverings and hospital bed sheets for doctors, nurses and patients. As the raw material is pure natural, it has the advantages of anti allergy, easy to wash and comfortable to wear. The underwear made of this material looks like the second skin of human body

the underwear made of PLA fiber has the advantages of loose and comfortable, air permeability, moisture absorption and sweat absorption; Compared with the traditional polypropylene and polyester non-woven bags, the non-woven bags made of PLA fiber have the characteristics of biodegradability and environmental friendliness, and can replace plastic bags and paper bags< The invention of biological polylactic acid will open up a green industrial chain. according to the introduction, polylactic acid and traditional petroleum based plastics have the same or similar use performance and sanitation performance. After completing its use function, it can be quickly degraded into fragments or fragments that are easy to be absorbed by the environment in the natural environment, and completely degraded into carbon dioxide and water over time, Finally, return to nature. The popularization and application of PLA is a typical low-carbon product, which is of great significance to face the “three rural issues”, replace the non renewable fossil resources, alleviate the “white pollution” and “greenhouse effect” among all the materials that can be used as biomass plastics, PLA has the most development potential. On the one hand, due to the easy availability of raw materials and large-scale intensive production, and more importantly, the excellent physical properties and plasticity of PLA products, PLA products can completely replace the traditional petroleum based plastics in most fields. 1n addition, because L-lactic acid, the monomer material of polylactic acid, is an endogenous active substance in human body, polylactic acid products are non-toxic, non repellent and can be absorbed by human body. 1t can be used to make medical orthopedic materials and drug carriers and can be safely used in human body< At present, PLA has become a global investment hotspot. 1t is estimated that in 2009-2012, with the production cost of PLA approaching the traditional plastics and the vigorous expansion of market application, the popularization and use of PLA will enter the peak period, and the construction boom of PLA will start all over the world
