Replace cotton into textile materials: What material so magical?
With the improvement of living standards, human consumption has increased year by year, and the demand for textiles has also been increasing. On the contrary, the cultivated area on the earth is gradually shrinking. This will make the supply of cotton, the main raw material for textiles, more and more nervous. The gap in the future may be getting bigger and bigger. With the improvement of living standards, human consumption has increased year by year, and the demand for textiles has also been increasing. On the contrary, the cultivated area on the earth is gradually shrinking. This will make the supply of cotton, the main raw material for textiles, more and more nervous. The gap in the future may be getting bigger and bigger. According to relevant persons, in the past three years, as the prices of grain crops such as wheat, corn and rice increased steadily, the area planted with cotton was gradually retreated. In the past two years, the acreage under cultivation in the country has been reduced by about 14 million mu. Therefore, the development of textile raw materials to replace cotton, make up the lack of cotton this gap, it is particularly important. The development of energy-saving, environmental protection of new technologies, new materials, is the trend of the textile industry. At present, a considerable part of new materials have been developed. Our reporter collected a part of new materials for this purpose. A survey was conducted jointly with the first textile network. Textiles and apparel industry stars evaluated these new materials. Among them, bamboo fiber won the title of " Creative Star "and" Prospect Star ", the new plantar hemp fiber access to" Environmental Star "and" low-cost Star. " Corn, seaweed fiber Environmental index: ★ ★ creative index: ★ low cost index: ★ ★ ★ ★ outlook index: ★ ★ ★ comprehensive evaluation: biodegradable, anti-UV six or seven years ago, foreign non-cotton movement has begun, everyone gradually Reduce the wear cotton products, and go to the plant direction, corn fiber (polylactic acid fiber, PLA fiber) become a good substitute for cotton. Now many domestic enterprises have also developed a new type of bio-based fiber and fabric derived from corn. Corn fiber is corn, wheat and other starch as raw material, after fermentation into lactic acid and then polymerization, spinning and made of synthetic fibers, is to complete the natural circulation type. The fiber has biodegradability, soft and smooth corn fiber, high strength, moisture absorption and breathability, processed products are silky luster and comfortable skin feel and feel, good drapability, good heat resistance and UV resistance, Take good performance. Because the fiber completely does not use chemical raw materials such as petroleum, its waste can decompose into carbon dioxide and water under the action of microorganisms in soil and seawater, and will not pollute the earth's environment. Since the starting material for the fiber is starch, the regeneration cycle is short, about one to two years, and carbon dioxide produced by the plant can be reduced by photosynthesis of plants in the atmosphere. Another kind of textile fiber, seaweed fiber, has many new features that are not found in traditional fibers. Its flame retardancy is 10% higher than the international standard and it will not open fire in the air. Compared with the traditional terrestrial fibers and synthetic fibers, it can save the land and purify the environment, and the production process is completely low-carbon green. Seaweed fiber also has some radiation, antibacterial, moisturizing effect, in the biomedical, high-grade clothing, environmental protection and other fields have broad application prospects. Bamboo fiber environmental index: ★ creative index: ★ ★ ★ ★ ★ low cost index: ★ ★ outlook index: ★ ★ ★ ★ ★ comprehensive evaluation: high quality and high price bamboo fiber is the use of China's extensive growth of natural bamboo as raw material, Into regenerated cellulose fiber, different from natural bamboo fiber, belongs to chemical fiber. It is understood that in the domestic market, a common culture of bamboo fiber material shirt priced at about 33 US dollars, Japan, a bamboo fiber suit market price as high as 500 to 1,000 US dollars. The development of regenerated bamboo fiber and advocating "using bamboo instead of cotton" can not only ease natural fiber tension but also open up a new way for the rational utilization of abundant bamboo resources in our country. Bamboo fiber fabric natural antibacterial, antibacterial, anti-UV effect after repeated washing, after the sun can still guarantee its original features, it is because the bamboo fiber in the production process, through the use of high-tech production technology, So that the formation of these features are not destroyed, so its antibacterial effect was significantly better than other products. It is different from other fabrics with antibacterial agents, anti-UV agents and other finishing agents added in the post-treatment so that it does not cause any allergic adverse reactions on the human skin but has a health effect and a bactericidal effect on human skin and is a real pro Skin health products, a wide range of applications. However, the raw material of bamboo fiber is much higher than that of cotton due to the mature technology of extracting raw materials other than cotton, and its origin is limited. Therefore, the price of bamboo fiber is relatively high when it is made into clothes. Feather fiber environmental index: ★ ★ ★ creative index: ★ ★ ★ low cost index: ★ ★ ★ prospects index: ★ ★ ★ ★ comprehensive evaluation: ultra-warm, wide use of chicken hair fiber development and utilization, but also become the current researchers concerned about the new Hot areas. China's development and application of feathers, especially the development of down such as duck down, goose down, has long been widely used in garments, home textiles and other fields. However, for the development and application of feather poultry, especially the research and development of feather fiber, at present, China is still in the initial stage of research and development. In recent years, China's scale of chicken resources increased rapidly, feather production is considerable. However, due to problems with domestic feather collection, a significant portion of feather feathers were treated as rubbish. According to Zhu Baoyu, an expert on textile and research institutes, at present, the development and application of feather fibers in foreign countries have involved the fields of national defense, apparel and apparel. Poultry feathers containing keratin up to 85%, and is rich in 18 kinds of amino acids and a variety of mineral elements, is a valuable natural resource. Feather fiber development has a very good development prospects. Carbonized chicken feather fiber can be used as hydrogen storage material. Experiments have shown that the storage of hydrogen with carbonized feather fibers will greatly improve existing hydrogen storage technologies and may overcome the current barriers to the use of hydrogen in automobiles, trucks and other machinery. In particular, carbonized chicken feathers green hydrogen storage, protein natural fiber biodegradable. Pheasant hair can be used as a new generation of body armor. In recent years, the British Ministry of Defense has made pheasant hair the most effective body armor. This new generation of body armor made of pheasant feathers is far lighter and cheaper than the current Kevlar fiber bullet-proof vests. Pheasant feathers unique, high value, can be made of high Luo, satin, brocade, silk clothing, but also can be made of feather fan, feather painting, toys and handicrafts. Feather or made of advanced air filter paper material. Feather fiber containing paper, feather fiber content accounted for 51%, wood pulp accounted for 49%, environmental protection is self-evident. It has been determined that air filter paper made from a mixture of feather fiber and wood pulp can be made to 5 microns thick. The ultrafine filtration of feather fiber filter paper can block various airborne allergens (dust) from the filter paper and reduce air pollution syndrome The incidence of more suitable for home and office use. In addition, with feather paper can also be made of diapers, the weight of light than ordinary diapers into two, but the adsorption capacity doubled. The development and production of light and dense high-strength synthetic materials with chicken fiber can also be used for office equipment, automotive interior parts, the hull outer side, railway sleeper facilities and so on. New plant hemp fiber environmental index: ★ ★ ★ ★ ★ creative index: ★ ★ ★ ★ low cost index: ★ ★ ★ ★ ★ prospects index: ★ ★ comprehensive evaluation: breathable, natural, but lack of comfortable hemp products because of its natural style and Breathable, antibacterial, loved by consumers, such as pineapple fiber, banana fiber, and so on, to further satisfy the modern people's pursuit of nature, return to the natural psychological needs. Pineapple fiber, also known as pineapple, is extracted from pineapple leaves. After separation, drying and other processing the formation of fiber, woven fabric easy printing and dyeing, sweat breathable, crisp and not crinkly, wearing very comfortable. Pineapple fiber is a combination of many fiber bundles, each of which consists of a collection of 10-20 fibroblasts. Fiber surface roughness, longitudinal gaps and holes, transverse branches, no natural distortion. The spinnability of pineapple fiber is superior to that of jute, but it is inferior to flax. Appropriate degumming treatment before spinning can improve spinnability. Pineapple fiber and cotton blend can produce denim; pineapple fiber and silk blend can be woven into high-level dress fabrics; pure pineapple fiber yarn produced by rotor spinning as weft yarn, interwoven with other raw material yarns to produce various decorative fabrics and Furniture fabrics; wool and pineapple fiber blended yarn can produce suits and outerwear fabrics; pineapple fiber and cotton blended yarn can be woven curtains, sheets, furniture fabrics, towels, carpets; polyester / acrylic / pineapple fiber blended Yarn can be used to produce knitted women's coats, socks and more. Because pineapple fiber yarn is more powerful and more hair-rich than cotton yarn, pineapple fiber is also the ideal material for the cord fabric and the cords with rubber belt. The canvas made of pineapple fiber is stronger than the cotton canvas of the same specification. The banana fiber is taken from the banana stem soft fiber endothelium, after drying, refining, defibering and made of fiber, mainly composed of cellulose, hemicellulose and lignin, the cellulose content of linen and jute relative to Low, so the fiber luster, softness, elasticity and spinnability are poor, banana single fiber length and jute similar to the relatively short linen, chemical degumming of the fiber can be used for cotton spinning. Recycled Fiber Environmental Index: ★ ★ ★ ★ Creative Index: ★ ★ Low Cost Index: ★ Outlook Index: ★ Comprehensive Evaluation: Recycled man-made fibers, make the best use of plastic bottles can also be a raw material for clothes, several plastic bottles have been processed Can be transformed into clothes, made of recycled polyester plastic bottles made of recycled fibers, and then made into clothes fabric. This saves up to 6 tons of oil per ton of recycled fiber compared to virgin fiber made from petroleum while reducing the significant emissions of industrial waste gases. It is reported that this process not only reduces the environmental pollution of plastic waste treatment, but also ease the growing polyester industry pressure on the demand for non-renewable resources such as oil. Outdoor product manufacturers are increasingly inclined to make outdoor products from recyclable materials. Fishing nets, plastic bottles, coconut shells and even discarded tires are good materials for recycling. Coffee is the love of many people and the coffee grounds made from coffee are of great use today. As long as the recovered coffee grounds are heated to 160 ° C to 180 ° C, the carbonized and carbonized coffee grounds can be changed in their physical structure, processed, and drawn to become yarn. Braided into a fabric with coffee fiber fiber yarn, because the fabric fiber has the effect of removing odor, easy to dry, especially anti-UV, very popular with ladies. It is said that the coffee grounds produced by making a cup of coffee produce two T-shirts of coffee yarn.
