Experts Interpret &Nbsp; Who Will Replace Cotton As The Main Raw Material Of Textile?

With the improvement of living standards, mankind

According to the people concerned, over the past 3 years, with the increasing price of grain crops such as wheat, corn and rice, the cotton planting area has been losing step by step. In 2 years, the planting area has decreased by 14 million mu.

Therefore, it is particularly important to develop textile materials that can replace cotton and make up for the shortage of cotton.

The development of new technologies and materials for energy conservation and environmental protection is the general trend of the textile industry.

At present, a considerable number of new materials have been developed. Reporters gathered some new materials for this purpose, and made joint surveys with the first textile network. The textile and garment industry made star rating on these new materials.

Comprehensive evaluation: degradable and UV resistant

Six or seven years ago, the non cotton movement in foreign countries had begun. People gradually reduced their wear of cotton products and walked towards plants. Corn fiber (PLA fiber, PLA fiber) became a good substitute for cotton.

Many domestic enterprises have also developed new bio based fibers and fabrics derived from corn.

Corn fiber is a synthetic fiber made from corn and wheat starch, which is converted into lactic acid through fermentation and then polymerized and spun. It belongs to the natural circulation type.

This fiber is biodegradable, corn fiber is smooth and smooth, strong strength, moisture absorption and breathability, processed products have silky luster and comfortable skin touch and feel, good drapability, good heat resistance and anti ultraviolet function, good wearability.

Because the fiber completely does not use petroleum and other chemical raw materials, its waste can be decomposed into carbon dioxide and water under the action of microorganisms in soil and sea water, and it will not pollute the earth's environment.

Because the raw material of the fiber is starch, its regeneration cycle is short, about one to two years. The carbon dioxide produced can be reduced by plant photosynthesis in the atmosphere.

Another kind of textile fiber, seaweed fiber, has many new characteristics that many traditional fibers do not have. Its flame retardancy is 10 percentage points beyond the international standard, and it does not show fire in the air.

Compared with traditional land fibers and synthetic fibers, it can save land and purify the environment, and the production process is completely low carbon green.

Seaweed fiber has certain radiation protection, antibacterial and moisturizing effects, and has broad application prospects in biomedicine, high-end clothing, environmental protection and other fields.

Bamboo fiber

Comprehensive evaluation: high quality and high price.

Bamboo fiber is made from natural bamboo which is widely grown in China. It is made of regenerated cellulose fiber. It is different from natural bamboo fiber and belongs to chemical fiber.

It is understood that in the domestic market, a bamboo fiber material general cultural shirt sells for about $33, and the market price of a bamboo fiber suit in Japan ranges from $500 to $1000.

The development of regenerated bamboo fiber and the promotion of "replacing bamboo with bamboo" can not only alleviate the tense situation of natural fibers, but also open up a new way for the rational utilization of bamboo resources in China.

The natural antibacterial, bacteriostasis and anti ultraviolet effects of bamboo fiber fabrics can still guarantee their original characteristics after repeated washing and drying. This is because the bamboo fiber in the production process, through the use of high-tech production technology, makes the composition of these characteristics not broken, so its antibacterial effect is obviously better than other products.

It is more different from other fabrics added with antibacterial agents and anti ultraviolet agents in post processing. Therefore, it will not cause any allergic adverse reactions to human skin. Instead, it will have health care function and bactericidal effect on human skin. It is a real skin care product with wide application scope.

However, raw materials are much higher than cotton because the raw materials of bamboo fiber are not as raw as cotton, and their origin is limited. Therefore, the price of bamboo fiber is higher.

Comprehensive evaluation: Super warm and versatile.

The development and utilization of chicken feather fiber has also become a new hot spot for researchers.

The development and application of feather, especially feather down, such as duck down and goose down, has been widely applied to clothing, home textiles and other fields in China.

However, the development and application of poultry feather, especially the development of chicken feather fiber, is still in the initial stage of research and development in China.

In recent years, the scale of chicken raising in China has increased rapidly, and the output of chicken feather is considerable.

However, due to the problem of chicken feather collection in China, a large part of chicken feather is treated as garbage.

According to Zhu Baoyu, an expert in Textile Research Institute, at present, the development and application of chicken feather fiber abroad has involved national defense, clothing, clothing and other fields.

Poultry feather contains more than 85% keratin, and is rich in 18 kinds of amino acids and mineral elements. It is a valuable natural resource. It can be called "a href=" http://info.texnet.com.cn/bin/search.cgi t=list_f&terms=%B0%B2%BB%D5&c=&d=2008-04-01&Submit=%CB%D1%CB%F7 "target=" _blank "> Anhui jealousy.

The development of chicken feather fiber has a good development prospect.

Carbonized chicken feather fibers can be used as hydrogen storage materials.

Experiments show that storing hydrogen with carbonized chicken feather fiber will greatly improve the existing hydrogen storage technology and overcome the obstacles existing in the use of hydrogen materials in automobiles, trucks and other machinery.

In particular, carbonized chicken feather storage hydrogen is green and environmental friendly, and protein natural fiber can be degraded.

Pheasant feather can be used as a new generation of bulletproof vest.

In recent years, the British Ministry of defense has made the pheasant feather the most effective bulletproof vest. This new bulletproof vest made of pheasant feather is lighter and cheaper than the bulletproof vest made by Kevlar.

The pheasant feathers are unique and of high value. They can make high-grade robe, satin, brocade and silk garments, and also make feather fans, feather paintings, toys and crafts.

Chicken feather is also used to make high-grade air filter paper.

In the paper containing chicken feather fiber, chicken feather fiber accounted for 51%, wood pulp accounted for 49%, and environmental protection advantages were self-evident.

According to the measurement, the air filter paper made from mixed materials of chicken feather fiber and wood pulp can achieve 5 microns thick. The hyper fine filtration of chicken feather fiber filter paper can block all kinds of allergen (dust) in the air on filter paper, reduce the incidence of air pollution syndrome, and is more suitable for family and office use.

In addition, diaper cloth can be made from chicken feather paper. Its weight is 20% lighter than that of ordinary diapers, but its adsorption capacity is twice as high.

We use chicken feather fiber to develop and produce light-weight and high-strength synthetic materials. It can also be used for office equipment, car interior decorations, hull outboard, sleeper facilities of railway passenger cars, etc.

Comprehensive evaluation: breathable, natural but not comfortable.

Because of its natural style, breathability and antibacterial properties, hemp products are very popular among consumers, such as pineapple fiber and banana fiber, which further satisfy the modern people's psychological needs of pursuing nature and returning to nature.

Pineapple fiber, also known as pineapple fiber, is extracted from Pineapple leaves.

After separation, drying and other processed fibers, the woven fabrics are easy to print and dye, sweat and air permeability, crisp and wrinkled, and comfortable to wear.

Pineapple fiber is composed of many bundles of fiber bundles, and each bundle consists of 10-20 single fiber cells.

The surface of the fiber is rough, with longitudinal cracks and holes, pverse branches, no natural distortion.

The spinnability of pineapple fiber is better than that of jute and is inferior to that of flax. The proper degumming before spinning can improve spinnability.

Pineapple fiber and cotton blended can produce denim; pineapple fiber and spun silk blended can be made into high-grade dress material; pure pineapple yarn produced by rotor spinning is used as weft yarn, interwoven with other raw yarns, and can produce all kinds of decorative fabric and furniture cloth; wool and pineapple fiber blended yarn can be used to produce suit and outer garment fabric; pineapple fiber and cotton blended yarn can be used for weaving curtain cloth, bed sheet, furniture cloth, towel, carpet, etc. polyester / acrylic / Pineapple fiber blended yarn can be used to produce knitted female coat, socks and so on.

Because pineapple fiber yarn has stronger strength and hairiness than cotton yarn, pineapple fiber is also the ideal material for producing cord belt and triangle belt core of rubber conveyor belt, and canvas made of pineapple fiber is stronger than cotton canvas of same specification.

Banana fiber is a fiber made from banana stems. It is made of cellulose, hemicellulose and lignin by drying, refining and defibrating. Its cellulose content is lower than that of flax and jute, so its luster, softness, elasticity and spinnability are all poor. The length of banana fiber is similar to that of jute, and its relative flax is shorter. Chemical degumming fiber can be used in cotton spinning.

Comprehensive evaluation: recycled artificial fibers and best use of materials

Plastic bottles can also be used as raw materials for clothing. After processing, several plastic bottles can be pformed into clothes, and recycled polyester plastic bottles are used to make regenerated fibers and then made into clothing fabrics.

Compared with the crude fiber made from petroleum, the production of tonnes of recycled fiber can save 6 tons of oil and reduce the discharge of industrial waste gas.

It is reported that this process not only reduces the environmental pollution caused by plastic waste treatment, but also alleviates the pressure on the growing polyester industry's demand for non renewable resources such as oil.

Nowadays, outdoor products manufacturers are increasingly inclined to make outdoor products with recyclable materials.

Fishing nets, plastic bottles, coconut shells and even used tyres are good recycled materials.

Coffee is the favorite of many people, and coffee grounds made of coffee are also of great use nowadays.

As long as the recovered coffee grounds are heated to carbonization at 160 to 180 degrees C, the physical structure of the coffee residue can be changed after carbonization, and the yarn can be turned into yarn after processing.

The use of coffee dregs fiber yarns to weave fabrics is due to the fact that fabric fibers have the effect of removing peculiar smell and are easy to dry, especially UV protection, which are very popular with ladies.

It is said that the coffee residue produced by making a cup of coffee can produce two coffee gauze T-shirts.
