Latest Research Results Of Fiber Materials In The United States

　　 Another masterpiece of Clegg biology laboratory in the US: spider silk Composite fiber

Researchers at the Clegg Biotechnology Laboratory in the United States announced that under the cooperation of many spiders, they used spider silk gene chain to create a new type of restructured spider silk, called "scarlet" fiber.

Clegg biological laboratory is a famous global biological Technology Development Company in the United States. Before that, they have made many achievements. The first generation of products is based on the first generation of silk. Because this silk is not strong enough, it can not be used in the industrial sector. To this end, Clegg biotechnology laboratory has bred 20 new types of transgenic silkworm eggs, their way is to give silkworm embryos injected with Fraser DNA embryos, including modified spider genes, and then screened will optimize the new silkworm. Gene integration To other genomes. In 2011, the market of raw silk products reached US $4 billion. Subsequently, the company continued its development with the aim of developing more robust and light weight silk fibers and expecting mass production including synthetic materials and building materials needed for bulletproof vests, automobiles and sports equipment.

Because spiders are too aggressive and hard to breed, researchers have cultivated transgenic animals and produced spider silk proteins. But this is not enough, because the protein components that only produce these materials are not enough. They must imitate the spinning method of spiders, and spiders also spin silk.

Later, the lab claimed that they had conquered the main challenge, namely, how to make lightweight, stronger fibers than steel. The company has been world-famous for developing silkworm babies that can spit silk. To put it this way, they use a very earthy way: randomly inserting spider genes into the gene map of silkworms. Now these silkworms can spit out the "silk thread" which is far better than the normal silk. But these fake silk threads are not real spider silk, and their strength is somewhat different from that of genuine ones.

Texas A&M University: layers of nature Flame retardant fiber

Researchers at Texas A&M University have developed an eco friendly foam nanocoating that will someday be used in cotton fibers, textile clothing and polyYaan foam. It uses chitosan and other renewable materials, and has potential applications. It is especially suitable for children's clothing, household textiles, aviation, military clothing and other protective clothing.

The project's Associate Professor, mechanical engineer and research director, Dr. clen Lin, has explored the use of water-based solutions to create gas barrier film clay based nano brick coatings on a layer of coating technology, and then used in flame retardant materials. He was originally used in the foam outer layer and was tested by the National Institute of standards and technology. It was found that the coating foam did not decompose. Later, it was found that the coating was not cracked, not delaminated, and lighter than other flame retardant coatings. The inner layer has no damage, but it has a good protective effect on the internal heat energy. The coating soaked in foam reduced the rate of degassing and reducing the heat release rate by half.

Nitrogen and phosphorus create a foam thermal shield during the expansion and foaming process of polymer coatings containing phosphorus and nitrogen. This method is applied to cotton fiber and the result is satisfactory. Because of the rich nitrogen content, phytic acid phosphorus promotes the abundance of phosphors. The United States Department of agriculture pointed out that the ASTM test method washing test found that after 10 times of water washing, its performance has not changed a bit. Experts believe that 20-30 washes will not change, no matter nylon, cotton fiber or polyester. Therefore, the flame retardancy of fabrics can be enhanced.
