Development And Development Of New Fiber Leading Function And Health

Of the new fibers reported this year, there are banana fiber, double protein fiber, pearl fiber, Hayes Moore fiber, polylactic acid fiber, super fine coolsmart sweat fiber, high strength high modulus polyethylene fiber and high count fiber.

If the fibers are lined up according to their popularity, journalists believe that the lowest popularity is banana fiber.

Of course, the emergence of banana fiber is not this year.

However, this year, we have made two breakthroughs in the extraction and spinnability of banana fiber.

First, the bio enzyme - oxidative degumming technology has been developed independently. This technology has achieved a good effect on fiber degumming, and the fineness of the fiber can reach 1600~2000 or even higher. It lays the foundation for spinning the high count yarn of banana fiber.

The two is in the spinning process. Jiangxi East Asia Bar Limited by Share Ltd and Donghua University have creatively used the method of stretch cutting.

Compared with the cut-off method, the length of the fibers is better by using the stretch cutting method, which is conducive to making full use of fibers and improving the spinnability of the fibers, making it possible to spin high count yarns.

Now, we have made use of BA (banana) fiber to produce 40 pure yarn of pure banana (banana) banana fiber and 21 cotton yarn blended with cotton, viscose, silk and so on.

The double protein fibrin double protein fiber is also a new face of the fiber family.

Abandoned animal fur, dandruff, hair, insects and milk by-products, vegetable oil byproducts in the past can only be used as feed, waste or simply processed into other products, but now it has become a good raw material for textile fiber.

Puyang Tianyuan Protein Fiber Co., Ltd. adopts modern biochemical technology to synthesize the textile materials with rich collagen protein and achieve the perfect combination of animal and plant protein.

At present, their technology has already made seven invention patents and a new patent.

The double protein fiber has the characteristics of breathability, warmth retention, dry and comfortable, and also has the characteristics of natural antibacterial and insect resistant. The rich collagen can serve as a nourishment for the skin by pporting nutrients from the skin.

At the same time, it also has the mechanical properties of synthetic fibers.

Now, with the cooperation of the major fabric enterprises, Tianyuan has developed 10 large series of more than 100 kinds of fabrics, including worsted, woollen, woven jacquard, knitted fabrics and other fabrics.

The double protein fiber can be blended with wool, rabbit hair, camel hair, cotton, silk and hemp. It can also be blended with nylon, acrylic, polyester, viscose, Tencel, Model, copper ammonia fiber, bamboo fiber, chitin, corn fiber and so on.

Pearl fiber pearl fiber was successfully developed by Donghua University and the new spinning technology development center of Shanghai in July 2007. The Shanghai Kenai pearl blended regenerated cellulose fiber (hereinafter referred to as pearl fiber Wei) has been popularized through the national level technical appraisal.

Since last year, pearl textile has attracted a lot of interest from textile and garment enterprises both at home and abroad. Some well-known brands, such as Lu Tai textile, Aili Fang, Ordos, Ordifen, Guangdong Jinlong, and Fuji home textiles, have developed a series of underwear, shirts and home textiles, which are loved by consumers.

Pearl fiber has good wearability and health care function, and has attracted many foreign businessmen's interest.

Now, functional fiber is favored by more and more garment enterprises. As an example, the functional textiles produced by domestic super fine Coolsmart sweat permeable and moisture permeable fibers have both the touch and refreshing feeling of cotton clothing and the comfort of wearing. Coolsmart

This kind of fiber is a new generation of polyester fine denier short fiber developed independently by the Silk Textile Co., Ltd., which has many shapes and fine grooves. The tube wall also has air permeability, which effectively improves the disadvantages of the hydrophobic polyester fiber. By experiment, the water absorption height of Coolsmart fabric is 4~5 times higher than that of the conventional polyester fabric, and it is superior to that of pure cotton fabric.

The key to this product is product design and unique spinning methods.

The silk company has tackled 6 key points and more than 60 key technologies in the production process. After expert identification, the moisture absorption and sweat perspiration of the products reached the level of similar products abroad, leading to the leading domestic technology level, which filled the gap in China.

With the increasing shortage of petroleum resources, polylactic acid fiber has been developed in developed countries instead of petrochemical raw materials.

Polylactic acid (PLA) fiber is one of the most important textile materials.

However, polylactic acid (PLA) fibers have high requirements for polylactic acid (LAC) materials during their preparation process.

At present, under the joint research of Donghua University and Shanghai synthetic fiber research institute, the problem has been solved finally, and the production process of PLA fiber with independent intellectual property rights has been developed.

Polylactic acid processing requires high raw materials.

According to Professor Hu Xuechao of Donghua University, the relative molecular mass of raw materials is not the only factor affecting the spinning performance of PLA. The factors such as racemization and monomer residue will affect the spinnability of PLA.

Polylactic acid can be divided into several kinds of optically active polymers, including polylactic acid, poly (lactic acid), poly (lactic acid), poly (lactic acid) and poly (lactic acid). Their properties are quite different. Only L-polylactic acid is suitable for spinning, and the purity of raw materials is high, and the residual amount of monomer should be as low as possible.

In addition, in order to ensure the good melt spinning properties of polylactic acid, the relative molecular weight distribution should also be narrow. Only when the above properties of the raw materials meet the requirements can they be used to prepare PLA fibers.

Hauser Moore fiber chitin fiber may have been heard of before.

Huaxing Group successfully launched Hayes Moore fiber using chitin materials this year.

According to Hu Guangmin, chairman of Huaxing Group, compared with the traditional chitin fiber, Hayes Moore has the following advantages: one is high purity: the traditional chitin fiber is added with boric acid, viscose and other related auxiliary materials, haismol is pure chitosan fiber, in the production process does not add any auxiliary materials, the purity is 99%.

Two, the bacteriostatic effect is good: Hauser Moore fiber has been tested by the state authority, the inhibition rate to Staphylococcus aureus is 100%, the bacteriostasis rate to Escherichia coli is 98%, and the rate of Candida albicans is over 65%.

The three is high technology content.

Hayes Moore (medical chitosan) has obtained the national invention patent, spinning, printing and dyeing, medical dressing, high-grade underwear design and many other technologies, and applied for the national utility model patent. The production capacity of similar products is the first in China.

The maximum weight of the fiber rope made of high strength and high modulus polyethylene fiber is 8 times that of the same thick and thin wire rope.

If you cut it with a pair of stainless steel scissors, the knife will be blunted for a minute after continuous shearing.

At present, this fiber has been able to mass production in China, and has broken the monopoly of the technology in the United States and Holland for a long time.

This is the result of more than 10 years of development of the chemical fiber Institute of Donghua University.

High strength and high modulus polyethylene fibers not only have very high relative molecular mass, but also have high crystallinity and high orientation structure.

Polyethylene has a high molecular weight of about one million, which greatly reduces the defects in macromolecules. In addition, the technology of gel spinning combined with ultra drawing technology helps to form chain chains from the intergranular structure to an extended chain structure, so as to form a continuous crystalline structure.

It is suitable for rope, bulletproof, protective materials, military and civil helmets, sailing, rowing and other equipment.
