What fabric is warm in winter and cool in summer?
According to French news reports, all kinds of environmentally friendly plant fiber fabrics have become the new highlights of the 2007 Paris Spring International Fabric Exhibition. Although the price of these new fabrics is higher than that of ordinary fabrics, their environmental protection and natural characteristics make them the best-selling products at the 2007 Paris Fabric Exhibition. More and more consumers, designers and textile manufacturers begin to pay attention to and produce this kind of textiles. Recall that two years ago, the so-called green fiber fabrics were only limited to traditional fibers such as cotton fibers. Nowadays, all kinds of fruit fibers and plant fibers have become upstarts in the natural fiber industry. At the 2007 Paris International Fabric Exhibition, all kinds of new natural fiber products competed with each other, among which textile fabrics made of soybean protein fiber, bamboo fiber and ramie fiber were especially favored by buyers. According to statistics, there were more than 830 exhibitors at the Paris Fabric Exhibition in 2007, most of whom were from Asia. At the same time, they brought new natural fiber products, which sold well in this exhibition. The reporter learned that due to the improvement of environmental awareness and the deepening of understanding of biological products, people began to realize the advantages and benefits of new products such as genetically modified cotton. Although this kind of product is about 30% more expensive than traditional fiber, due to the increasing demand of high-end consumers for this kind of fiber, this kind of new product has increasingly become the main component of many high-end textile products, and it is expected to have a very good market sales prospect. Texworld Paris International Fabric Exhibition is known as the golden key to open the European and American markets. TexWorld in every field attracts thousands of visitors and buyers, with an exhibition area of nearly 26,800 square meters, located in ParisLaDé fense's A, A 1, A2, B, C, D, E and F pavilions. Texworld leads the development trend of the world textile industry, and once again proves its position in the textile industry exhibition industry with many professional visitors and high-quality exhibitors. Most tourists (76% of the total) come from Europe. The development trend and product development of new textile fabrics such as accessories, cotton textiles, denim, embroidery, multifunctional textiles, fibers, knitwear, lace, linen, printing and dyeing, silk, design style, trade publications, trends and wool [Abstract] With the arrival of the new century, high-tech development is very rapid, as is the textile field integrating chemistry, physics, biology and electronics. At present, the development trend of textile fabrics is 1, and advocating nature, fineness, softness and comfort are the main styles of fabrics. 2. Textile processing pays more and more attention to the scientific and technological content of its technology, and traditional textiles realize their brand-new visual and tactile effects through new technology processing. 3. Pluralistic integration, integration of tradition and high technology, nostalgia and futurism, popularity and uniqueness. , is an important feature of modern fabric development. 4, the development of green products and green processing technology is conducive to the protection of the ecological environment. According to the development trend of textile fabrics and people's requirements for fashion, comfort and functionality of clothing, it is considered that wearing textile fabrics should have the following characteristics. First, an important aspect of the development of multi-component fabrics with textile raw materials is raw materials. At present, optical fiber has received unprecedented attention and development. On the one hand, traditional natural fibers constantly improve their properties, tap new characteristics and give fabrics a good wearing effect. On the other hand, new chemical fibers are constantly emerging, and the fiber circles all over the world analyze the characteristics of natural fibers, and through scientific and technological research, develop a new generation of high-performance, multifunctional and highly simulated new differential fibers, so that chemical fiber fabrics will develop into bionic fabrics. 1, Tencel (lyocell) 2, Modal3, nylon staple fiber 4, Coolplus5, bamboo fiber 6, soybean fiber 7, new elastic fiber 8, tri-fiber 9, new synthetic fiber 10, and functional fiber blending of new chemical fiber and natural fiber in different proportions are important directions for the development of garment textile fabrics. Second, the production and processing technology of diversified yarn morphology and texture, fabric structure and finishing technology are important factors that constitute popular fabrics. The development and breakthrough of these aspects depend on two aspects; 1, the rapid transmission of ideas and information, and the mixing of various design consciousness and ideas make the creative space expand to the greatest extent. 2, refers to the technical progress and breakthrough in spinning, weaving, finishing and other aspects, and constantly improve product quality. There are five key processes in textile processing: design, raw materials, spinning, weaving and finishing. Its main processing new technology; 1, modification of natural fiber; Development of high performance, high simulation and multifunctional differential fiber: development of new chemical fiber blended composite technology. 2. Develop new compact spinning and single spinning; Developing spinning technologies, such as air-jet spinning, siro spinning and bicomponent spinning; Research on the technology of untwisted area with less wool yarn: increase the use of advanced blowing-carding unit, fine winding and self-winding device; Increase the specific gravity of combed yarn. 3. Develop new weaving technology and electronic jacquard technology; Actively adopt new looms to increase the proportion of shuttleless looms. 4. Research on digital jet printing technology: increase the application of low temperature plasma technology in tops and finishing; Developing biological enzyme finishing technology; Deepen the coating composite finishing technology and develop various composite products. 5. Popularize and apply digital design technology, vigorously develop CAD computer-aided fabric design, style design and color design, and establish a rapid response mechanism of design system. Modern fabrics should have texture and texture effects, mainly through structural design and new processing. In popular fabrics, composite yarns and composite structures are widely used. With the help of CAD design, various yarns, various weaves, various colors and patterns are skillfully combined to make the products more fashionable and beautiful. 3. Pay attention to green technology and develop environmental protection products. With the globalization of global economy, international trade is developing towards liberalization. By the end of 2004, all textile trade will cancel quotas and return to liberalization, and some original trade protection measures and tariff barriers will gradually disappear. However, the "green barrier" built to protect human health and living environment also followed. In particular, some developed countries use their advanced environmental protection technology to prevent products from other countries from entering their own markets by raising environmental protection standards. At present, "Oeko-Tex Standard/KOOC-0/00", a symbol of textile commodities with great influence, has been formed in Europe, and ISO/KOOC-0/400/KOOC-0/,ISO/KOOC-0/4004 and ISO/KOOC-0/40/KOOC-have been officially promulgated by the International Organization for Standardization. Facing the challenge of "green barrier", China textile industry must establish the concept of green marketing, attach importance to the development of environmental protection products and the promotion of green processing technology. 1, from the aspects of new product design, raw material selection, processing and packaging, we should consider the requirements of environmental protection laws and standards. 2. Actively research and develop clean production, safe and harmless green technologies, and transform the traditional textile industry with high and new technologies. Actively strive for ISO 14000 environmental protection certification and "Oeko-Tex 100" ecological textile certification. Attaching importance to environmental protection is the general trend, and developing ecological textiles is the key word of 2 1 century. We must attach importance to this trend, do the above well, break through the "green barrier" in international trade, expand exports, and at the same time implement green protection, and resist any behavior that harms China's environmental protection and people's health in import trade. 1. The warp direction of the grid is woven by two groups of warp yarns and double warp beams of single mulberry silk and matte rayon. The weft direction is woven by three groups of weft yarns: high count cotton yarn, thick count rayon yarn and flax yarn. Five kinds of raw materials with different properties are selected with changeable warp density, and single-layer and double-layer core-filling complex structures are used with changeable weaving weft density to give full play to the world's latest multi-arm double warp beam eight-color weft selection and variable weft density weaving. After weaving, scouring and dyeing, the product feels soft, elegant and unique. In the double-layer structure, linen yarn is the core, coarse yarn contains livestock, and the sharp contrast of fineness, warp and weft density and organizational structure forms a concave-convex grid three-dimensional effect, which is novel and unique. 2. Ribbon georgette yarn uses a mulberry silk to strengthen warp twist, uses a mulberry silk to strengthen weft twist, and uses two mulberry double-palace yarns to process two groups of weft yarns, skillfully using the disparity of raw material fineness and the contrast between fineness and roughness to change the configuration of weft density. After weaving, scouring and dyeing, the products are unique in style, delicate, soft, as light as cicada's wings, elastic in texture, embedded with rough and slightly bright stripes, perfectly integrated, elegant and elegant. It is reported that these two fabrics were designed and woven by a company in Wujiang, and now they are deeply concerned by textile operators. Recently, a new textile-based lighting material came out, which can absorb solar energy during the day and provide lighting for millions of people living in places without electricity facilities at night. Six such portable luminous samples are equivalent to the brightness of a 60-watt light bulb. A 14 ounce shoulder strap can be transformed into a lighting ceiling; A 2.5 kg shoulder bag is a lantern when opened; A 3 pound backpack can also be used as a lighting tool. An 8-ounce cushion can be rolled up or opened to provide enough reading space. This portable light source model can be made into portable bags, even tools, mats and bags with shoulder straps, which can provide lighting for families, classrooms and small rural factories, and also improve the living conditions of developing living communities. Sheila Kennedy, the main researcher of the project, said: "The basic structure of this portable light source is decentralized, and it does not need to be connected to any power supply when it is used." Scientists at the University of Michigan developed this luminous cloth by using the following technology: solar cells woven into the cloth absorb solar energy and convert it into voltage. When the lithium battery is charged by such a voltage, the obtained electric energy provides energy for the light-emitting diodes woven into the cloth. Textiles used to make luminous fabrics are made of translucent and anti-reflective fabrics, which are very durable and can enhance the brightness of light. Charging every 5 hours is enough to provide 5 hours of lighting for reading and work. At present, Kennedy is trying to turn this sample into a business model with little return, so that semiconductor manufacturers are interested in turning this portable light source into a portable commodity. So that community members can use it with a small amount of money when they need it. A new textile fabric recycling waste silk and its environmental protection function 1. Silk fiber recovered from waste silk is used to regenerate waste silk and plant fiber through biochemical technology. The produce sheath-core silk fibroin fiber 2 has good hygroscopicity and air permeability; 3. It has skin-friendly, comfortable and antibacterial effects of silk protein; It is a new textile fabric with waste silk regeneration and environmental protection. Background 1 Because the lightness and smoothness of silk restrict its development in autumn and winter silk products, the company is now trying to explore the structural characteristics of silk microfibers. Successfully developed the real silk terry fabric and laminated multi-layer real silk warm knitted fabric with practical market value. The second company has undertaken more than 250 key scientific and technological projects in five national "Fifth Five-Year Plan" and national cocoon and silk development risk fund projects, and has achieved a number of technological achievements that have great influence in the industry and have been well transformed. For thousands of years, the mission given to clothing by human beings is nothing more than keeping out the cold, being beautiful and being fashionable. What will we wear in the future? When new high-tech is integrated into clothing fabrics, all kinds of clothes with novel functions also come into our real life from fantasy. In the future, we will wear it. "Warm in winter and cool in summer" temperature-regulating clothing: China enterprises cooperated with foreign countries by using "space technology" to successfully develop phase-change temperature-regulating fiber, and produced "warm in winter and cool in summer" temperature-regulating clothing for the first time in China. The phase-change thermoregulation fiber is coated with a layer of microcapsules containing phase-change materials by high-tech means. At normal body temperature, this substance exists in solid and liquid. When this kind of fiber is used to make clothes, when the phase change material enters a higher temperature environment from a normal temperature environment, it changes from a solid state to a liquid state and absorbs heat. When it enters the lower temperature environment from the normal temperature environment, the phase change material changes from liquid to solid, releasing heat, thus slowing down the change of body surface temperature and maintaining comfort. "Shape memory" clothing: Italian Mauro Tagliani designed a shirt with "shape memory function". When the outside temperature is high, the sleeve of the shirt will automatically roll from the wrist to the elbow within a few seconds; When the temperature drops, the sleeves can automatically recover. At the same time, if people sweat, clothes can also change shape. The secret of this "shape memory function" is that NiTi memory alloy material is added to the shirt fabric. Clothes cut with shape memory fabrics also have super wrinkle resistance. No matter how you rub it, you can recover in 30 seconds, and you don't have to worry about clothes wrinkling anymore. Intelligent protective clothing: British scientists have developed a special kind of clothing, which will quickly harden when it is hit to slow down the impact force, and then immediately soften without limiting the flexibility of the wearer. This kind of clothing fabric is usually light and elastic, but it will harden within11000 seconds when it is hit. The stronger the impact force, the faster the response. This is because this material is composed of flexible molecular chains, which will hook each other when driving at high speed. Its principle is a bit like that of a car driving on wet sand: it will sink when driving slowly, but when driving at high speed, the sand grains will stick together and the car will not sink. This fabric can be used to make flexible knee pads, competition clothes, sports helmets and sports shoes that can adapt to the load change during running. Vitamin T-shirt: If you are worried about not getting enough vitamin C from your diet, you can wear a vitamin-rich T-shirt. Recently, Japan invented this kind of fabric containing vitamins. This kind of fabric introduces provitamin which can be converted into vitamin C into traditional textile fabrics. This provitamin will react with human skin to produce vitamin C. A T-shirt produces vitamin C equivalent to two lemons. Wearing this T-shirt, people can take vitamin C directly through their skin. How amazing! Electronic clothing: future clothing will integrate people with the digital world. In electronic clothing, even the application of computers will become as common as zippers. Now American scientists have developed textiles with conductive function, and researchers have invented a textile keyboard installed on clothes, with which people wearing shirts can easily play beautiful music. I believe this new material will soon become the new favorite of fashion designers. Fashion runway is not only a publishing place for fashion designers' artistic innovation, but also a new stage for science and technology to show their charm. Self-cleaning disposable clothes: As early as 1950s, clothes with self-cleaning function appeared in movies, and now scientists are turning this fantasy into reality. Researchers mixed titanium dioxide particles into traditional textile fabrics to make clothing fabrics with self-cleaning function. Under the irradiation of sunlight, the titanium dioxide particles in this fabric can catalyze the decomposition of oil stains, dirt, pollutants and harmful microorganisms on the fabric surface. Scientists in China have prepared nanofibers with superhydrophobic surfaces from amphiphilic polymer polyvinyl alcohol. The hydrophobic groups of this kind of fiber are outward and the intermolecular hydrogen bonds are inward, which makes the surface energy of the whole system decrease and shows superhydrophobicity. Clothes and ties made of this fabric are not harmed by dirt such as rain, grease and ink, thus achieving the function of self-cleaning and washing-free. Antibacterial and health-care clothing: silver, zinc oxide and other particles with sterilization and disinfection can be mixed into traditional textile fabrics to make new fabrics with antibacterial and health-care functions. This fabric can effectively remove the unpleasant smell on the body and kill the harmful bacteria attached to the clothes. Such products can be bought on the market at present. Invisible clothing: Japanese scientists have recently developed an invisible clothing that can make people wearing clothes partially invisible. This kind of invisibility cloak is called "optical camouflage" cloak, which is made of "retroreflective substance". The clothes are covered with reflective beads, and several small cameras are installed on the clothes. When someone puts on clothes, the background image shot by the camera will be displayed in front of the clothes, and the foreground image will be displayed behind the clothes, so that the wearer can be integrated with the environment and achieve the invisible effect. Anti-static and electromagnetic shielding clothing: the dry air in office buildings often makes us face the trouble of being attacked by static electricity. Conductive polymer materials can be compounded into traditional textile fabrics, so that the fabrics have good antistatic and electromagnetic shielding effects. As long as you wear clothes made of this fabric, you can prevent static electricity from invading wherever you go and effectively shield the human body from electromagnetic waves. With the development of science and technology, more and more magical new clothes with special functions will come out, bringing us a better and healthier life. It is expected to develop "changeable" colors. At present, Toza Hinas is studying nanoparticles that can decompose gases, such as ozone, which can really reduce smog. He even used nano to produce colors without dyes, by reflecting the desired colors with nano of appropriate size. He said that the principle of antivirus is to use nanoparticles with the same size as viruses or bacteria. Hinas Toza has bolder ideas. He wants the nanoparticles on the fabric to move and recombine, thus changing the color of the fabric. He said, "In this way, the blue shirt you wear to work can turn black when there is a dance at night, so you can wear the same shirt to work and go to the dance." The new women's fabric appeared beautifully in the market, and after embossing, tabletting and waxing, the significance of fashion was marked with shining notes. Most of the fabrics of these products appear in a relatively calm appearance, mainly in the most basic plain weave and twill weave, and the raw materials are also mainly conventional polyester, nylon, rayon and polyester cotton yarn, but after finishing, they completely present another appearance, either classical or avant-garde. Women's clothing materials have long occupied a place with see-through clothes and transparent chiffon, and the finished clothing, whether layered or hazy, will exquisitely depict the wonderful figure of women. Very thin fabric is very popular, which is made of pure polyester filament or polyester cotton interwoven, with low density and high weaving difficulty. Make the finished fabric smooth, soft and elegant in quality. This "difficult" variety has a higher added value. Today's women's windbreaker has become fashionable and personalized. Inadvertent waist tightening and lacing always depict the graceful amorous feelings of women and become a graceful street scenery. Island fiber is the most important choice for this kind of fabric. It is a kind of composite fiber with different shrinkage. The finished fabric has velvet feeling and good suede effect. Designers have different weights of fabrics according to market demand, which is especially suitable for fashion and windbreaker. Therefore, the interests of dealers and manufacturers are consistent, and there is naturally a win-win situation. At present, the dress code for white-collar women is elegant and noble. In the overwhelming noise of men's wool-like fabrics, women's fabrics also continued this route, boldly adopting the "LeLisi" commonly used in men's fabric design. This kind of fiber has fine texture, smooth cloth surface and outstanding wool feeling. Some of them are embedded with soft medium gray tones and light gray-blue straight stripes, and the fabrics are compatible with romantic, subtle, elegant and advanced connotations. Because the distance between gray and blue stripes is different, this fabric has become a series, and the design of clothing manufacturers is more free. The combination of width and narrowness gets rid of the usual formality of striped and plaid clothes and expresses a free mood. Consumers can also play freely according to their own requirements, and can properly interpret customs. A new cotton velvet satin fabric interwoven with polyester and cotton yarn has attracted the attention of merchants. The width of this product is 1.8 meters, the front fabric has a shiny effect, and the back fluff is full and delicate. It is understood that the fabric is made of 50D triangular shaped polyester yarn and 32S cotton yarn interwoven into satin weave, woven on air-jet loom, and then dyed, printed, softened and shaped. The whole product feels soft, bulky, refreshing and comfortable, which is suitable for personal wear. The printing process of this fabric is mainly transfer printing. The printed patterns are rich and colorful, mainly including roses, jasmine, orchids and other 10 flower varieties for customers to choose from. According to the analysis of the operating company, the pajamas market will also enter the peak season, and the sales of pajamas fabrics will also become the highlight of the market.
