Corn fiber
In recent years, the U.S. Food Council and Cargill-Dow Polymers Co., Ltd. have cooperated with Japan Bell Spinning Fibers Co., Ltd. to jointly develop a new environmentally friendly fiber made of polylactic acid fiber made from corn. Fiber, trade name "INGEO". Corn fiber is developed by the United States joint venture CARGILL-DOW. CARGILL is a company mainly engaged in the development of agriculture and shell technology. DOW is a major producer of chemical raw materials. In 1997, the two companies teamed up with CARGILL-DOW to jointly develop production. Corn fiber technology. It also authorized Japan's Zhongfang Fiber Company and Shimadzu Corporation to jointly develop the corn fiber with the trade name "LACYRON". In 2003, Taiwan's Far East Textile Co., Ltd. was also the second authorized producer of corn fiber in Asia after Japan Bell Spins. The trade name is still "INGEO".
The benefits of corn fiber:
Most of the chemical fiber raw materials are derived from petroleum. Their products pollute the earth during the decomposition process. The corn fiber is a PLA plant fiber derived from corn. Using the concept of environmental protection, due to the high decomposition of plant fibers, it can achieve environmental protection. The effect. The combustion value of PLA fiber is as low as that of paper. After combustion, it does not produce gases such as nitrides, and the pollution of incineration is also lighter.
According to the introduction of the Japan Fiber Science, the initial cycle of starch regeneration of "LACYRON" fiber is short, about 1-2 cycles.
The cycle from raw material to product:
Starch began to be made into polylactic acid----Polymerized fiber made of PLA fiber--Any kind of product was made--After use, it was discarded--Breaked in soil or treated with water----Microbial decomposition ---- Generate carbon dioxide and water - through photosynthesis - into raw starch.
Through the recycling process, both the original raw starch and the photosynthetic use can be used to reduce the carbon dioxide content in the air.
PLA has high decomposability, and it is decomposed by turrison method. It is almost completely decomposed in 2-3 years. Seawater immersion method, active river mud method and standard bundle method are used. The result is also completely decomposed, and its solution is very high.
The characteristics of corn fiber coupled with the characteristics of knitted fabrics make the fabric more fluffy and soft to the touch, the fabric has strong morphological stability, good gloss appearance, and the hydrophobic properties have dry feeling on the skin and no irritability to the skin.
Corn fiber has more complete natural circulation and biodegradable properties and is very beneficial to the earth's ecology. Corn is the most abundant agricultural product in the world and it is inexhaustible.
Needless to say, there are still many problems in the production of corn fiber fabrics, and the technological conditions are not mature enough to be improved and developed. However, corn fiber is an ecological fiber with great potential for development. It is worthy of the development of the industry. I believe that in the near future, various problems will arise. After being overcome, corn fiber is the most popular environmental textile material in the 21st century.
