Yao Mu, Academician Of Chinese Academy Of Engineering: New Material Lays Foundation For Upgrading Material

< p > 2013, large quantities of medium and low count pure cotton yarn imported from China were imported to India, Pakistan, and the developed textile giants, such as the United States, Britain, Germany, France and Italy, resumed the "re industrialization", resumed the production capacity of the textile industry, and began to squeeze the high-end market of China's textiles.

In such a double squeeze environment, China's textile industry must pform and upgrade, and step out of the road of innovation.

< /p >

< p > the most important material foundation for industrial pformation and upgrading is new textile fiber materials.

New textile fiber materials are widely used in natural fibers, regenerated fibers and synthetic fibers.

< /p >

< p > new types of natural fibers include new seed fiber, bast fiber, vascular bundle fiber, Animal Plush fiber, silk and so on.

For example, the length of the long staple cotton is 44~46mm, and the fiber density is 0.78dtex. It can spin high quality superfine cotton yarn.

Ramie also found a new super fine variety, linear density 2.5dtex.

The average diameter of superfine wool fiber can be up to 16.5 m, and the fiber length is 80~120mm.

In recent years, the whole genome map of silkworm has been collected in China, and genetically modified (green) mulberry silk has been developed on this basis.

Natural colored mulberry silk has many varieties, such as green, yellow, brown, red and so on, and is sold in batches to produce special products.

In addition, in recent years, artificial rearing spiders have made progress in China, and began to experiment with artificial rearing and extraction of dragline (dragline) fibers from spiders of black widows and other species, which have high specific strength and specific modulus.

< p > new regenerated fiber and < a href= "//www.sjfzxm.com/news/index_c.asp" > semisynthetic fiber < /a > including new viscose fiber, alginate fiber, chitin fiber, polylactic acid fiber and so on.

The new synthetic fibers include new functional synthetic fibers and new high-performance fibers.

Conventional synthetic fibers (polyester, nylon, acrylic, vinylon, polyvinyl chloride, spandex), with their own functions, add new functions to become new synthetic fibers and have a wide market.

The new type of high performance fiber has many functions, such as high strength, high modulus, super high strength, super high modulus, high temperature resistance, high insulation, high chemical stability and so on.

These new fibers have opened up new areas of textiles, including bulletproof helmets, bullet proof clothing, anti cut gloves, banknote trucks, rocket shells, rocket hood, rocket nozzle throat, spacecraft, artificial satellites, large aircraft brake discs, nuclear submarines, parachutes, Spacecraft Recovery and drop parachutes, climbing safety rope, and anti virus bacteria safety clothing, anti gas safety clothing, fire fighting and fire safety clothing, etc.

< p > cotton textile industry must avoid middle and low grade pure cotton products in the current development, and apply high performance new functional fiber blending as far as possible.

In the past 10 years, spinning technology has made rapid progress. Cotton textile enterprises should also see that the combination of filament and cotton fibers should not be neglected while the multi fiber varieties are blended.

On the basis of old ring spinning, go spinning and rotor spinning, based on compact spinning, siro spinning, poly fiber spinning, siro Phil spinning, parallel spinning, jet spinning, air-jet vortex spinning, low torque spinning, and embedded composite spinning, recently, Italy's a has introduced the double strand filament core wrapped "href= //www.sjfzxm.com/news/index_c.asp" > composite ring spinning < /a > (Dual FXTM).

Nearly half of these spinning methods are suitable for joining yarn with filament and staple fiber, which is also one of the development directions.

< /p >

< p > on the basis of traditional a href= "//www.sjfzxm.com/news/index_c.asp" > woven > /a >, different weft insertion methods such as film shuttle, rapier, water jet, jet and so on; different opening ways such as dobby, jacquard, jacquard and so on; combined with warp knitting; double warp axis, multi warp axis (six warp axis, even 30 axis or more) three-dimensional three-dimensional composite weaving; wide width (1.2 m to 2.8 m), super wide (6 m), ultra wide width (16.5 m) and other widths types, which provide broad fields for weaving, and can be used for new product development of different uses, especially for the development and production of industrial textiles.

< /p >

< p > weaving preparation process is also expanding the working space: sizing of different sizing or less slurry; pre weaving yarn processing includes singeing, lye mercerization, liquid ammonia mercerizing, yarn dyeing, yarn dyed dyeing (the same yarns are dyed with different colors on the same yarn), and so on.

< /p >

< p > in order to adapt to the current environment, China's textile industry must face the new demands that are constantly developing in the middle and high-end market, apply high performance and new functional fibers, innovate and develop new varieties, new uses and new fields, occupy new markets, attach importance to the introduction of new equipment, new technologies and new skills, attach importance to the fine, precise, exquisite and exquisite products, create new brands with artistic and cultural concepts, and pay special attention to product performance in order to stabilize the occupation of the market. More attention should be paid to the development of new fields and new uses of industrial textiles and the development of new markets.
