Jiaxin Silk (002404): Textile Industry With Unique Bionic Silk Mark Ushered In Subversion

Recently, Jiaxin Technology (002404. SZ) announced the company's roadshow on November 2. The company's investment in super silk technology has made a breakthrough in the research and development of new materials. Through the gene combination of silkworm and black widow spider, the performance of domestic silk has been improved, and the strength of domestic silk has been 3.86 times stronger than that of ordinary silk, reaching the international advanced level. Super bionic spider silk can be flexibly used in military, biomedical and other fields due to its performance advantages, which is expected to become the next outlet of textile industry.

A-strand unique bionic Silk Mark

According to the survey summary of the company's investors, the company's investment in super silk technology mainly focuses on the research and development of super bionic silk of silkworm spider. Through the gene combination of silkworm and black widow spider, the performance of silk is improved, and a new material of protein silk fiber is developed. At present, a breakthrough has been made in technology. The company plans to start from the application of clothing materials, and gradually promote the market-oriented process of bionic silk products.

The super bionic silk of silkworm spider developed by Jiaxin silk subsidiary super silk technology is not a simple synthetic extraction technology, but a more difficult and widely used transgenic cultivation technology downstream. The black widow spider dragline silk gene is introduced into the silkworm baby and the bionic silk is obtained. In addition to the characteristics of black widow spider traction silk with high strength and toughness, the bionic silk has the characteristics of high strength and toughness, It is still pure natural animal protein material. According to the research data, the dragline silk of black widow spider is one of the most excellent dragline silks among more than 44000 spider species.

Based on the many performance advantages of black widow spider silk imitation, the product can be widely used in the military field, such as bulletproof vest, bulletproof helmet, aircraft carrier interception cable, parachute, multi-functional military uniform and other military equipment manufacturing. In biomedicine, biomimetic silk is composed of pure natural animal protein, which makes it can be used to make artificial joints, artificial tendons, artificial ligaments, wound sealing materials, prosthetic limbs, heart valves, etc. In terms of materials, raw silk can also be used in the manufacture of high-strength structural materials and composites, high-strength protective clothing, ropes, cables, etc.

Raw silk leads new material revolution

The development of new materials is the focus of future science and technology development strategy. The United States, Europe, Japan and other developed countries and regions have listed the new material technology as one of the key technologies in the 21st world when formulating national science and technology and industrial development plans. Among them, silk fiber has been the key research and development direction in the field of new materials because of its wide application range. It is found that spider dragline silk is the protein silk fiber with the best mechanical properties in nature, and its strength is 5 times that of steel. How to add the properties of spider dragline silk into traditional silk products has become the research goal of many fiber technology companies.

As early as 2018, the US army began testing bulletproof "spider man suits" made of genetically modified silk. In the same year, bolt threads, the maker of synthetic spider silk, announced the completion of round D financing of 123 million US dollars. After seven years of research, bolt threads has made significant progress in the research and development of synthetic spider silk. The company combines genetically modified yeast, water and sugar together to produce raw silk by fermentation.

Kraig biocraft laboratories, Inc., another spider silk fiber developer, is committed to producing a new generation of protein polymers and protein fibers through its own genetic engineering technology. The company's R & D team focuses on the R & D of recombinant spider silk and other high-strength polymers. At the end of 2019, Kraig biocraft laboratory announced that its R & D team had found a new spider silk protein, which was superior to its two flagship products, monster silk ? And dragon silk ?。 By recombining the DNA in this spider silk protein, Kraig biocraft can produce new textile materials, opening up new markets for the company's spider silk manufacturing technology.

The industry believes that the invention of artificial spider silk will bring a far-reaching revolution to the textile industry. In the future, bionic silk will become the mainstream of the industry. The application of science and technology in the field of textile has a potential market of trillions. At present, Jiaxin silk Co., Ltd. holds 20% shares of super silk technology, and the rest is held by Professor Zhong Boxiong and his wife. Jiaxin silk executives pointed out that once the conditions for mass production are met, the company will vigorously increase investment. Jiaxin silk's first mover advantage in bionic spider silk cultivation technology is expected to inject new vitality into its traditional business and help the company realize its vision of becoming a benchmark enterprise in the silk industry.
