Highlights of fabric research and development and more

Editor's note: The continuous advent of new products and new achievements, reflecting the domestic fabric companies take the initiative to develop high value-added products, to seek the development trend of new space, but also an important manifestation of the rapid development of the fabric industry. Fabric texture and texture, the function of clothing and visual effects have a significant impact, therefore, garment enterprises can not ignore the development trend of fabric products, from which to find opportunities and find the direction of future development. In recent years, China's textile fabric research and development by many domestic scientific research institutions, universities and textile and garment enterprises great concern and extensive participation, showing a rising trend, with antibacterial deodorant, fire retardant, waterproof breathable, oil repellent, anti-oil Oil, mosquito and other functions of new products after another. Throughout the study of textile fabrics, mainly reflected in improving the functionality of the fabric, the use of new fiber materials and recycled materials and other aspects. Improve the process to enhance the fabric function Enterprises pay attention to the development of new features of the fabric at the same time, but also pay attention to through the improvement of the process to improve the performance of the original fabric. Knitted fabrics are widely used in the production of sportswear, casual T-shirts, underwear and the like because of their characteristics of stretching, softness, wearing comfort and breathability. However, due to its own organizational structure of the knitwear, its dimensional stability, washed shape retention and appearance after washing generally worse than the woven fabric, to a certain extent, affect the performance of knitted fabrics. May 2009, Younger "with an annual output of 1,000 tons of high-value high value-added knitted fabrics finishing technical transformation project" through the acceptance, the successful solution to the long-troubled knit fabric batch liquid ammonia finishing technical problems. The project mainly from the improvement of the luster of knitted fabrics and increase the intelligence of two aspects to improve the process and optimize the process conditions, liquid ammonia finishing with ultra-soft finishing organic combination of liquid ammonia after the knitted fabric finishing, fabric soft, Feel soft and slippery, green bio-enzyme washing process to make the fabric lines clear, feel smooth, more comfortable to wear, giving knit fabric new textile new material taking function. Flame retardant clothing is also one of the key research and development. Due to the flammability characteristics of most textiles and the fire hazards in everyday life, the development and application of flame-retardant fibers and textiles have drawn much attention from all walks of life both at home and abroad. At present, many countries have formulated fire-retardant laws and regulations for textile and apparel. Britain, the United States, Japan and other countries have also stipulated that women, children, the elderly, disabled people's clothing and pajamas should have the function of flame-retarding by law, Product marked. Flame-retardant textile standards and environmentally friendly flame retardant production has therefore become an important research topic, the traditional brominated flame retardants are subject to increasingly stringent environmental and fire regulations, the future of flame retardants will also be more emphasis on environmental protection and ecological safety performance , And gradually realize halogen-free and ecological. The research and development of functional textiles in China is expanding to many fields such as environmental protection, medical treatment, health, mining, nanotechnology and chemical industry, such as research on electromagnetic radiation protection garments and their standards, development of outdoor sport functional textiles, printing and dyeing wastewater treatment, natural dyes and plant functions Dyes, silver-plated fibers, mosquito textiles, functional microcapsules, mulberry fiber, the development of medical recycle decompression socks. Development and application of new fiber New fiber fabric has become a hot spot for domestic fabric enterprises. Most of the new fiber fabrics are sold to foreign countries, welcomed by foreign customers, the current domestic garment enterprises using the new fiber fabrics are not many. Rose silk fiber. Soft silk fiber is a new type of differentiated fiber developed by Suzhou Hengguang Chemical Fiber Co., Ltd. Its raw materials are protein and cellulose fiber, which are derived from the renewable green plants in nature and are biodegradable and environment-friendly fibers. Sophie protein fiber containing the right amount of protein and a dozen amino acids on the human skin with affinity and health effects. At the same time, luster bright and soft, good absorption, release wet, brightly colored, soft, good drapability. Particularly noteworthy is that soft silk fiber soft and smooth, but also to improve the fabric feel the fiber. Soft silk fiber with far-infrared emission function, has a good thermal effect, improve the human microcirculation; with UV protection, is an excellent anti-UV fiber; with the release of negative ions function, the negative ion concentration of the fabric equivalent to the concentration of negative ions in the valley, comfortable Sexual line with the physiological needs of human skin. Rose is a cellulose fiber, when the heat is breathable, sweat; when the cold can moisturize, do not produce static electricity, soft and comfortable. When the human skin moisture in the 12% -15%, the skin smooth and elastic, dry skin will become dry once the skin is dry. The most comfortable relative humidity of the human body between 45% -65%, therefore, textiles must have certain hygroscopicity, breathability. Jiangsu Donghua Cotton Spinning Co., Ltd. further developed the soft silk fiber, and conducted a large number of tests on different blended ratios, different yarn count and different processing methods of the soft silk fiber. The newly developed soft silk yarn was provided to Knitted fabrics, seamless underwear and other downstream businesses. Pearl fiber denim fabric. Pearls have long been regarded as good skin care products, and now, this effect has been used in denim clothing. Donghua University Institute of Clothing Technology, led by Associate Professor Li Dongping led the development of pearl fiber denim fabric has been successfully developed and will be put on the market. The fabric retains and optimizes the denim style, based on the addition of pearl fiber to increase the garment's skin care functions. According to Li Dongping introduction, added in the denim fabric of pearl fiber called Kennametal pearl fiber, from Donghua University and Shanghai New Type of spinning technology development center jointly developed. The quality inspection department of the country, added the pearl fiber fabric, the far-infrared emission rate of 0.84 or more, the fabric UV protection factor (UPF) up to 35-50, while ordinary clothing fabrics far infrared emissivity Generally below 0.78, UPF value between 15-17. In other words, garments made from Richeno's pearl fiber fabric have far-infrared thermal and UV protection features than most garments. The pearl fiber fabric to wear on the body, pearl fiber in more than 10 kinds of amino acids and trace elements will also participate in the metabolism of the body through the way to improve the skin and personal clothing between the microenvironment, in the mechanism of health effects. Corn fiber. Corn ear shell cellulose extracted, and then purified to form a corn fiber. This fiber-making technique is low cost and can be made into a T-shirt from about 3 pounds of fiber extracted from the maize hulls. Corn fiber drape, comfort and feel good, with good curl, flexibility, shrinkage, but also with disperse dyes, molding processability, low flammability, low smoke, and less susceptible to UV influences. More importantly, corn fiber is easily biodegradable and does not pollute the environment. Made of corn PLA (polylactic acid) fiber instead of polyester and wool blend, not only will not destroy the original feel of wool style, but also with the blended yarn made of fabric can also be low temperature treatment. As this fiber is made of corn and other raw materials, harmless to the human body, after use can be composted or decomposed in the natural environment into carbon dioxide and water. In addition, more and more biological and mineral raw materials enter the textile field sequentially, and more new materials will be added to the textile industry to open up new fields for the fabrics, For noodles, clothing and even the entire textile industry to provide a broader space. The rise of recycled materials American ski lovers Austin's ski suits are made from recycled Coke bottles. This fabric has a fashionable name - "sustainable fabrics", made from recycled cola bottles, old clothing fibers, natural hemp, non-toxic dyes and the like. Even more expensive than the market products, environmental enthusiasts Austin still readily accepted. In fact, this use of waste, fiber recycling clothing technology in Europe and the United States has existed for many years. H & M, Top Shop and other brands have begun to store a prominent place in the store recycling products made of clothing, people are increasingly accepted the concept of low-carbon equipment. However, this is still a completely new concept in China. In the low-end industrial chain of recycling and processing of used clothes, in the remote areas of cities, many small garment recycling factories cut old clothes into mops or peasants' quilts and then sell them to more remote areas . Old clothes hard to return to the city's body. Now, a Japanese company will bring this kind of recyclable clothing materials to China. This new environmentally friendly fabric is called: ECO CIRCLE (ecological cycle), Teijin Co., Ltd. to provide Li Ning. This is a kind of fabric developed by Japan in 2002. The recycled polyester clothes are made into recycled polyester fiber fabrics through the steps of crushing, chemical reaction, polymerization and the like, and the old American outdoor Patagonia uses this material . "My clothes come from recycled materials, which come from all countries," said Kamei Kamei, president of Teijin Fiber Co., This is somewhat surprising, because this tailored fit suits look no different from ordinary clothes. In the global fashion of "old", the first global standard for textile and garment recycling (GRS) has also been introduced. An organization called a management affiliate certification agency classifies the product recycling standards into three levels: copper, silver and gold. The gold standard requires that the product contain 95% -100% recycled material, the silver standard product contains 70% -95% recycled material, and the copper standard contains not less than 30% recycled material. After this standard certification clothes will be linked to gold, silver, copper logo, so that consumers at a glance.
