Beautiful silk can also block "invisible killers" such as electromagnetic radiation.

With the extensive use of electrical equipment such as computers, mobile phones, and air conditioners, the new type of pollution source, electromagnetic radiation, has quietly hit people, which has a tremendous impact on the life and production activities of human society. Electromagnetic radiation pollution is significantly different from air pollution, water pollution and waste pollution. It is colorless, odorless and intangible. It is a pollution phenomenon that cannot be perceived by the senses. It is called "invisible killer" and has become the influence of today's world. Public health and serious problems that damage the ecological environment. Therefore, it is urgent to study fabrics with radiation protection.

The “Silk Anti-Electromagnetic Radiation Product Processing Technology Research and Industrialization” project completed by Wujiang Dingsheng Silk Co., Ltd. won the third prize of “Textile Light” Science and Technology in 2013. The project adopts silk and silver fiber. Through the innovative design of fabric structure, process optimization control and equipment improvement, it solves the technical problems of large difference in material expansion, uneven tension, easy oxidation of silver fiber and easy damage of fiber surface coating. The development of silk anti-electromagnetic radiation products not only makes silk fabrics have good radiation protection performance, but also enhances the core technology and technological innovation capability of enterprise silk deep processing.

Combining comfort and function

Studies have shown that the human body is disturbed by electromagnetic waves, which causes the original electric field of the molecules in the body to change, resulting in disordered ecological balance. Therefore, the development of new high-tech materials with anti-electromagnetic radiation function has great economic and social benefits for improving the health of our people and enhancing national strength. However, the current radiation-proof fabrics, such as composite metallized fabrics, alloy-coated fabrics, and electroless tin-plated fabrics, have the advantage of good shielding effect, but the radiation-proof suits are airtight, cannot be repeatedly bent, and are not resistant to washing and close-fitting. Clothes wearing this fabric not only have a tingling sensation on the skin, but also cause side effects such as skin irritation.

According to Wu Jianhua, the chairman of Wujiang Dingsheng Silk Co., Ltd., the leader of the project, “Silk anti-electromagnetic radiation products not only have excellent anti-radiation function, but also the silk fabric is smooth and soft, which can produce a subtle massage effect on the skin”. As a protein fiber, silk contains a variety of amino acids and has good affinity with the skin. In addition, the silk fiber is slender, and the surface is smooth and soft. Therefore, when it comes into contact with the skin during wearing, it will be well ventilated, hygroscopic and Wet and weak friction have a sense of comfort. At the same time, threonine and serine contained in silk can improve blood circulation, enhance the vitality of epidermal cells and prevent skin aging.

In addition, the fabrics of mulberry silk and silver fiber intertwined by special techniques, in addition to their excellent performance, also enhance each other. On the one hand, silk fiber has good antistatic property compared with chemical fiber fiber, and does not cause electrostatic attraction and any tingling sensation due to friction during wearing; on the other hand, the anti-wrinkle property of silver fiber makes the fabric have memory function. It does not wrinkle and overcomes the shortcomings of traditional mulberry silk fabrics.

Innovation in technology and design

Wu Jianhua introduced that the innovation of the project is reflected in two aspects: functional innovation and design innovation. The fabric is interwoven with silk and silver fiber. It has anti-radiation function, antibacterial, anti-mildew, anti-mite and other health care functions. It is smooth, soft, breathable and skin-friendly. These products are still internationally. For the first time.

In terms of design, the double-layer connection is designed independently, so that the surface of the fabric has a bag-like bubble floating, dye-dyed heavy-duty, single-layer houndstooth and other patterns, and the single layer uses the thickness of the raw material to change elastically, so that the surface has a relief feeling. This allows different radiation-proof silk and silver fabrics to have their own characteristics and can be used in different types of products.

Due to the use of “Fiber Queen” silk and silver fiber with good anti-electromagnetic radiation performance, the project has high technical requirements and long development cycle. First of all, it is necessary to overcome the technical problems of large-scale industrial production of new nano silver fibers, so that it can meet the large-scale use of silk radiation protection products. Secondly, it is reasonable to arrange the best warp and weft density when weaving silk and nano silver fiber, and the product specifications and process routes that can be smoothly weaved. Then, in order to make the product group richer, we must overcome the shortcomings of nano-silver fiber oxidization, and study the refining, dyeing, printing, finishing technology. And establish a test method for yarn-dyed, dyed and printed series of new functional fabrics such as mulberry silk silver fiber radiation protection, antibacterial and anti-mite.

Wu Jianhua said that silk anti-electromagnetic radiation products not only meet the functional requirements of anti-electromagnetic radiation, but also meet the general requirements of silk products, namely softness, skin-friendly, and skin aging prevention. At the same time, because of the use of silver fiber in the raw material, it has a good anti-mildew and anti-bacterial function, and is more popular among consumers.

Create a new milestone for special silk

Faced with the complex and ever-changing international economic environment and the continuous improvement of labor, raw materials and energy costs, traditional, low value-added silk products simply cannot adapt to the current situation. Continuously upgrading the core technology of silk deep processing and the ability of scientific and technological innovation, researching, developing and producing high-quality products that meet the needs of consumers, and owning independent brands, will undoubtedly become an important driving force for promoting the sustainable development of the silk industry.

Wu Jianhua pointed out that the successful research and development of the project will promote the transformation and upgrading of the silk industry, break through the traditional crafts and styles of silk fabric products, and create a new milestone for special functional silk fabrics, which has played a good role in the industry. At present, the project has achieved industrial production. Since it was officially put into the market in 2012, it has achieved good economic benefits, bringing profits to the company and bringing vitality. In addition, this product not only provides clothing manufacturers and consumers with more high-grade and novel fabrics, meets the growing needs of material and cultural life, and promotes the rational adjustment of industrial structure.

Silk is the accumulation of thousands of years of Chinese culture and a symbol of luxury and taste. China's silk trade accounts for 80% of global trade. However, today, China is only the most important raw material production and product processing, and the brand, design and marketing network are in the hands of foreign manufacturers. Wu Jianhua and other watchers in the silk industry believe that silk, as a representative of Chinese traditional culture, can be defined as both a textile industry and a cultural industry. The government should formulate relevant policies to support and encourage textile companies to accelerate technological innovation. At the same time, as long as each company makes its own products better, and establishes a reputation among consumers, it also establishes a brand, and together they can achieve a national silk brand.
