With the improvement of living standards, human consumption has increased year by year, and the demand for textiles has also increased. On the contrary, the area of ​​cultivated land on the earth is gradually shrinking, which makes the supply of cotton, the main raw material for textiles, more and more tense, and the gap in the future may become larger and larger.

With the improvement of living standards, human consumption has increased year by year, and the demand for textiles has also increased. On the contrary, the area of ​​cultivated land on the earth is gradually shrinking, which makes the supply of cotton, the main raw material for textiles, more and more tense, and the gap in the future may become larger and larger.

According to relevant sources, in the past three years, with the increase in the prices of wheat, corn, rice and other food crops, the cotton planting area has gradually lost. In the past two years, the national planting area has been reduced by about 14 million mu. Therefore, it is particularly important to develop textile raw materials that can replace cotton and make up for the shortage of cotton. The development of new technologies and new materials for energy conservation and environmental protection is the general trend of the textile industry. At present, a considerable part of new materials have been developed. This reporter collected some new materials for this purpose. In conjunction with the First Textile Network, the textile and garment industry conducted star ratings on these new materials, among which bamboo fiber won The “Star of Creativity” and “Star of the Future”, the new hemp plant hemp fiber won the “Eco-Star” and “Low-cost Star”.

Comprehensive evaluation: Degradable, anti-ultraviolet rays Six or seven years ago, foreign non-cotton sports have begun, everyone gradually reduced the wearing of cotton products, and in the direction of plants, corn fiber (polylactic acid fiber, PLA fiber) became a good substitute for cotton. Product. Now many domestic companies have also developed new bio-based fibers and fabrics derived from corn. Corn fiber is a synthetic fiber made from starch such as corn and wheat, which is converted into lactic acid by fermentation and then polymerized and spun, and is a natural circulation type. The fiber is biodegradable, the corn fiber is light and smooth, the strength is high, moisture absorption and breathability, the processed product has silky luster and comfortable skin feel and feel, good drape, good heat resistance and UV resistance. Good performance. Since the fiber does not use chemical materials such as petroleum at all, its waste can be decomposed into carbon dioxide and water under the action of microorganisms in soil and seawater, and does not pollute the global environment. Since the starting material of the fiber is starch, the cycle of regeneration is short, about one to two years, and the carbon dioxide produced by the plant can be reduced in the atmosphere by plant photosynthesis.

Another kind of textile fiber, seaweed fiber, has many new characteristics that traditional fiber does not have. Its flame retardancy exceeds the international standard by 10%, and it will not open fire in the air. Compared with traditional terrestrial fibers and synthetic fibers, it can save land and purify the environment, and the production process is completely low-carbon green. Seaweed fiber also has certain anti-radiation, anti-bacterial and moisturizing effects, and has broad application prospects in biomedicine, high-grade clothing and environmental protection.

Comprehensive evaluation: high quality and high price bamboo fiber is made from natural bamboo widely grown in China, and is made into regenerated cellulose fiber. Unlike natural bamboo fiber, it belongs to chemical fiber. It is understood that in the domestic market, a common cultural shirt with bamboo fiber material is priced at around US$33, and a Japanese bamboo fiber suit is priced at US$500 to US$1,000. The development of recycled bamboo fiber and the promotion of “returning bamboo with bamboo” can not only ease the tension of natural fiber, but also open up a new way for the rational utilization of abundant bamboo resources in China.

The natural antibacterial, antibacterial and anti-ultraviolet effects of bamboo fiber fabrics can still guarantee their original characteristics after repeated washing and sun exposure. This is because bamboo fiber adopts high-tech production technology in the production process. The ingredients that form these features are not destroyed, so their antibacterial effect is significantly better than other products. It is different from other fabrics that add antibacterial agents, anti-UV agents and other finishing agents in the post-treatment, so it does not cause any allergic adverse reactions to human skin, but has health care effects and bactericidal effects on human skin. It is a true pro. Skin care products, a wide range of applications.

However, the raw material of bamboo fiber is mature because of the technique of extracting raw materials that are not like cotton, and its production area is limited, so the raw material is much higher than cotton, so the price is relatively high when it is generally made into clothes.

Comprehensive evaluation: The development and utilization of super-warm and wide-purpose chicken fiber has become a new hot spot for researchers. China's development and application of feathers, especially the development of down, such as duck down, goose down, etc., has been widely used in clothing, home textiles and other fields. However, for the development and application of poultry outer feathers, especially the research and development of chicken feather fiber, the country is still in the initial stage of research and development.

In recent years, the amount of chicken resources in China has increased rapidly, and the production of chicken feathers is considerable. However, due to problems in the collection of domestic chicken feathers, a large part of the chicken feathers were treated as garbage. According to Zhu Baoyu, an expert at the Textile Research Institute, the development and application of chicken fiber in foreign countries has already involved defense, clothing and other fields. Poultry feathers contain more than 85% keratin and are rich in 18 amino acids and minerals. They are valuable natural resources.

The development of chicken feather fiber has a good development prospect. Carbonized chicken fiber can be used as a hydrogen storage material. Experiments have shown that carbonized chicken fiber storage of hydrogen will greatly improve existing hydrogen storage technology and may overcome the current barriers to the use of hydrogen materials in automobiles, trucks and other machinery. In particular, carbonized chicken feathers store hydrogen in a green environment, and protein natural fibers can be degraded.

Chicken feathers can be used as a new generation of body armor. In recent years, the British Ministry of Defence has made the chicken feathers the most effective body armor. This new generation of body armor made of chicken feathers is far lighter and cheaper than the current body armor made of Kevlar. The pheasant feathers are unique and can be used to make high-grade Luo, satin, brocade and silk garments. They can also be made into feather fans, feather paintings, toys and handicrafts.

Feather feathers are also the material for making advanced air filter paper. In paper containing chicken hair fiber, chicken fiber content accounts for 51%, wood pulp accounts for 49%, and environmental protection advantages are self-evident. According to the measurement, the air filter paper produced from the mixed raw materials of chicken feather fiber and wood pulp can be 5 microns thick. The ultra-fine filtration of chicken fiber filter paper can block all kinds of allergens (dust) in the air on the filter paper, reducing air pollution syndrome. The incidence is more suitable for home and office use. In addition, diaper can also be made from chicken paper, which is 20% lighter than ordinary diapers, but has twice the adsorption capacity. The development and production of light and dense high-strength synthetic materials with chicken feather fiber can also be used for office equipment, automotive interior parts, hulls, and sleeper facilities for railway passenger cars.

Comprehensive evaluation: Breathable, natural but lacking comfort linen products are deeply loved by consumers because of its natural style, breathability and antibacterial properties, such as pineapple fiber and banana fiber, which further satisfy the psychological needs of modern people to pursue nature and return to nature.

Pineapple fiber, also known as pineapple fiber, is extracted from the pineapple leaves. After being separated and dried, the woven fabric is easy to print, absorbs sweat and breathes, is crisp and wrinkle-free, and is very comfortable to wear. Pineapple fiber is made up of a number of fiber bundles, each of which consists of a collection of 10-20 monofilament cells. The surface of the fiber is rough, with longitudinal slits and holes, and branches in the lateral direction without natural distortion. The spinnability of pineapple fiber is better than that of jute, which is inferior to flax, and proper degumming treatment before spinning can improve the spinnability.

Pineapple fiber and cotton blend can produce denim; pineapple fiber and silk blend can be woven into high-grade dress fabric; pure pineapple fiber yarn produced by rotor spinning is used as weft yarn, interlaced with other raw yarns to produce various decorative fabrics. Furniture fabrics; fabrics made of wool and pineapple fibres can be used to produce suits and outerwear fabrics; pineapple fibres and cotton blended yarns can be used to weave curtain fabrics, bed sheets, furniture fabrics, towels, carpets, etc.; blended with polyester/acrylic/pineapple fibres Yarn can be used to produce knitted women's outerwear, socks and the like. Because pineapple fiber yarn is stronger than cotton yarn and has more hairiness, pineapple fiber is also an ideal material for producing cord fabric and triangular belt core wire for rubber conveyor belt; canvas produced with pineapple fiber is stronger than cotton canvas of the same specification.

Banana fiber is a fiber made by removing soft fiber endothelium from banana stems, dried, scoured and defibrated. It is mainly composed of cellulose, hemicellulose and lignin. Its cellulose content is higher than that of flax and jute. Low, so the fiber's gloss, softness, elasticity and spinnability are poor, banana single fiber length and jute are similar, relatively thin linen, chemical degummed fiber can be used for cotton spinning.

Comprehensive evaluation: Recycled man-made fiber and plastic bottles can also be used as raw materials for clothes. Several plastic bottles can be transformed into clothes after being processed, and recycled plastic fibers can be used to make recycled fibers and then made into fabrics. This produces 6 tons of oil per ton of recycled fiber compared to virgin fibers made from petroleum, while reducing the amount of industrial exhaust emissions.

It is reported that this process not only reduces the environmental pollution caused by plastic waste treatment, but also alleviates the pressure of the growing polyester industry on the demand for non-renewable resources such as petroleum. Today, outdoor product manufacturers are increasingly inclined to make outdoor products from recyclable materials. Fishing nets, plastic bottles, coconut shells and even used tires are good materials for recycling.

Coffee is the love of many people, and the coffee grounds made from coffee are now very useful. As long as the recovered coffee grounds are heated to 160 ° C to 180 ° C carbonization, the carbonized coffee grounds can change their physical structure, and then processed, added to the drawing, can become yarn. Weaving into a fabric with coffee slag fiber yarn is because the fabric fiber has the effect of removing odor, is easy to dry, especially UV protection, and is very popular among women. It is said that coffee slag produced from making a cup of coffee can produce two coffee gauze T-shirts.
