    Polylactic Acid Textiles Appear In World Expo

    2010/10/14 18:44:00 51

    Textile World Expo Cotton

    In September 27th, a male and female underwear exhibition made from natural raw materials, cassava, sweet sorghum and other agricultural wastes, such as straw and straw, was held in the private enterprise Hall of World Expo, Shanghai.

    The seemingly ordinary underwear of the model contains the world's leading high-tech -- polylactic acid environmental protection.

    textile

    Because of this kind of underwear raw material from pure natural, can effectively anti - allergy, easy to wash, wearing fluffy and relaxing and other advantages.

    The underwear made of this material is like the second layer skin of the human body.


    According to introduction, this is from Shanghai and Jay Liang biology.

    Material Science

    Ltd. and Shanghai green plastic Biotechnology Co., Ltd. under the leadership of Tongji University professor and doctoral tutor Ren Jie, jointly with Shanghai and Zhejiang relevant universities, research institutes, textile enterprises, etc., successfully produced polylactic acid as raw material to produce fiber and its series of underwear and environmental protection bags, and formed the industrialization manufacturing technology of polylactic acid and its textiles with independent intellectual property rights. At present, it has been put on trial in World Expo, Shanghai, and has been favored by tourists.


    What is

    Polylactic acid textiles


    Biomass polylactic acid is made from cassava, sweet sorghum and other crops, straw, straw and other agricultural wastes as raw material through biological fermentation to produce lactic acid, and then prepared by polymer polymerization.

    Polylactic acid fiber is made from polylactic acid resin regular spinning process. Its physical properties are close to nylon and polyester. Its permeability and handle are better than polyester. It is not easy to have static electricity. It has good biocompatibility and comfort. It can be made into multifilament, monofilament, short fiber, knitted fabric, nonwovens and so on. It can be used as underwear, baby diapers, sanitary articles for women, coats and socks, medical clothing such as doctors and nurses, surgical clothing, protective clothing, surgical cover cloth for patients and bed sheets for beds.


    The underwear made of polylactic acid fiber has the advantages of loose comfort, breathability, moisture absorption and sweat absorption. Compared with the traditional polypropylene and polyester non-woven bags, the non-woven environmental protection bag made of polylactic acid fiber has the characteristics of biodegradable and environment-friendly, and can replace plastic bags and paper bags.


    Polylactic acid will open up green industry chain


    According to the introduction, polylactic acid and traditional petroleum based plastics have comparable or similar performance and hygienic properties. After completing their functions, polylactic acid can be degraded rapidly into natural environment and can be easily degraded by environmental debris or debris. It will completely decompose into two carbon dioxide and water over time and finally return to nature.

    The popularization and application of polylactic acid is a typical low carbon product facing the "three rural issues", replacing non renewable fossil resources, alleviating "white pollution" and "greenhouse effect".


    Polylactic acid has great potential in all kinds of materials that can be used as biomass plastics.

    On the one hand, because of the easy availability of raw materials and easy large-scale intensive production, more importantly, polylactic acid products have excellent physical properties and plasticity, so that polylactic acid products can completely replace traditional petroleum based plastics in most of the fields.

    On the other hand, the polylactic acid monomer L- lactic acid is the endogenous active substance of human body, so polylactic acid products are non-toxic to the human body, and can not be rejected and can be absorbed by the human body. It can be used for the manufacture of Medical Department of orthopedics materials and drug carriers and is used safely in the human body.


    At present, polylactic acid has become a global investment hotspot.

    It is estimated that in the 2009~2012 years, with the vigorous development of polylactic acid application, the production of polylactic acid will start in the world.
