International textile territories known as "the eighth-largest man-made fibres"

Soy can wear?

Yes, there is a kind of "days of cashmere", is beans residues do material clothes. The inventor of the technology, called Li, Qi, he was hailed as a "quirky", because he spent 10 years time, 3800 Yuan price, finally got a dream become a reality.

In the flood of independent innovation, Lee, and his soybean protein fiber is a bit abrupt, high school and cultural identity of the farmers and a high level of scientific research results in the world — "soybean protein fiber," a modified into China in the world chemical areas of the first original technology, the only from our self-development and owns the intellectual property of man-made fibres.

Li, Qi invention with soybean meal made of silk thread.

A bit of a "one-minded" inventor Li Guan qi.

The development of the world directory of man-made fibres, "1999 Chinese Li Guan Qi invention of soybean protein modification fiber" traveled in the mesh.

Prior to this, 1935, the United States who WallaceH.Carothers invention polyester fiber (really good); 1944, r. goodmanson invention acrylic fiber (artificial wool); in 1955, Italy's Natalie's invention polypropylene fibre.

Lee, Chi's magic lies in the use of soybean oil pressed cake, after extracting protein isolate new biochemical engineering technology to produce a soybean protein fiber, the original food stuff to wear a new material.

At its forty-second meeting of the international rayon, this fiber is unanimously affirmed, received praise from different experts, international textile territories known as following the polyester, nylon, spandex, acrylic, polypropylene, viscose, vinylon global "after the eighth largest man-made fibres".

Soybean fiber dreams sprouted

With animal and vegetable proteins into natural fiber has a long history, ancient, human ancestor used silk to spinning cloth clothing, is based on this principle.

Time to modern humans began to try to follow this principle, an artificial methodology, extract from animal and vegetable protein fibers.

This technology has attracted many scientists win.

In the last century, Italy, United Kingdom, United States, the former Soviet scientists had separately from milk, peanuts, corn, soybean meal protein extraction too, but because of poor performance of pure spinning and cannot be interrupted by the textile processing. A day in 1991, Lee, odd in a code of the chemistry presentation abroad saw an article saying that soybean meal, soybean protein can be spinning. At that time, the country is in the cocoon wars, a ton of Mulberry silk price sold to who. People who know how to market rules: love and fantasy research officer Lee, if this technology has successfully developed a certain market.

At this point, the officer Lee as the reform and opening up after the first generation of rural entrepreneur, has been involved in over the flour processing machinery, oil machinery, feed machinery manufacturing, big gains.

The idea of soybean protein fiber produced only at the moment, then Li Guan Qi program with three years to overcome this problem, only to realize it has spent a decade of hard work.

Research and development, held in singular Li officer for years savings when suddenly appear inputs. This reporter has learned that, in those days, in order to exclude the outside interference, Li, qi to 2.8 million buy of "big brother" shutdown, unplug the fixed phone line, wrapped up in a book, thinking, doing experiments. Because of slow progress, Li, Qi repeatedly home economyalmost to the edge of bankruptcy, from 1996 to 1997, the most difficult times, even eating noodles at home is to borrow the flour mill. Has consistently supported his family worried about him, advised him to give up soybean protein fiber project. But Lee, more than the ordinary extraordinary dedication. He was even harder to leave 50 km outside of the test, Puyang get rare home all year round. Those days he's around is bundled into a bunch of books, magazines, of which a majority are in a foreign language. Lee, Chi-find local high school English teacher to help him translate. That year he bought books costs just 20 million Yuan. Li, qi to superhuman perseverance learned polymer chemistry, biochemistry, reagent chemical, analytical chemistry and fiber technology and other disciplines.

Ten years of hard work finally published in soybean fiber

"This project I did for ten years, the laboratory test, pilot, pilot and into industrialized production line, has a total of 800 test more than once every 3-4 days trial once.

I think anyway, engage in a scientific study is very, very hard, especially for me this project, it involves a lot of discipline, is a comprehensive engineering study, coupled with the low level of my culture, only high school culture, a multidisciplinary science books are required reading, feel very tired, 10 years engaged in the research project, the night the day thinking about the problem and doing it themselves, in a few seconds, ill dozens of times. "Later, in the State administration of grain Technology Conference, Lee, Ki memories of that time, still sigh.

"Yourself looking pressure is very large, why?, since 10 years engaged in research of investment costs have 3800 million, are themselves a

Human input, maybe not the, transformation, there is no benefit in productivity will ruin, they also have a feeling that is felt classmates, friends, relatives ask up and say you so long, what was successful or not successful? "asked it, others have asked time but not short, you do not have the ability, not the ability, therefore, in this regard, I also have a lot of pressure. " Li Guan Qi said.

Hard work pays off, in 1999, Lee, odd of soybean protein modification fiber production technology developed.

In June 2000, Li, Qi find Qingdao University, textile Engineering Department of Professor Han Kwang Pavilion, delegate Qingdao University comprehensive test performance of soybean protein fiber, testing has shown that soybean protein fiber has very clear advantages, of course, and all the fiber, also weak. Thus, efforts still need to continue. In 2001, Lee's official soy protein modification fiber developed, through the industrial production line spinning out the physical properties of full compliance of the protein fibers.

After setbacks, Li, qi to "soybean fiber" registered trade mark of a good — Winshow.

This is an international textile territories known as following the polyester, nylon, spandex, acrylic, polypropylene, viscose, vinylon "after the eighth largest man-made fibres", in the Chinese market is slowly finding a breakthrough, this is referred to as the "days of cashmere" man-made fibres, other desires like brothers, "" seven fiber, a hero arena.

Soybean fiber innovation point

(1) creative invention: proteins and PVA two substances through the graft, copolymer, blending, made from soybean protein fiber.

(2) found the point: control the polyvinyl alcohol and soybean protein blend liquid temperature process parameters, its soy protein in bio-enzymatic protein molecules, catalytic activity produces a protein and graft copolymerization of polyvinyl alcohol.

(3) of the soybean spherical protein modification for spinning technology.

Soybean spherical protein itself is spherical circle granular, is not spinning, you must have it modified, altered, changed line shape spatial structure of proteins.

(4) research as an Envoy to the fiber forming surface forming grooves when the section is the dumbbell and rules of technology, the polygon from fiber both moisture sexual function, also has good air permeability.

Soybean fiber is our original technology, it is the area of agriculture, food (soy) and deep processing technology, but also make food (soy) and deep processing products to new applications, and expand, expand to new uses.

Use the project science and technology, the production of grain by-products, soy fiber, saving alternative to cotton seed cotton land resource, China's annual production of cotton (lint) to 550 tons, soybean fiber if only instead of cotton, 25% of the total, up to 150 000 tonnes.

Yield per acre of land per 100 kilograms of lint, 150 000 tonnes of soybean fiber can save 15 million mu of arable land of cotton.

■ Research and development process

For pressing oil of soybean meal, one with immersion method for protein extraction and purification process, in which the stripped off, hybrid protein enzyme protein, with only one ball protein, then after purification of spherical protein dissolved completely, which is solubility of difficulties in the process of understanding and control of protein molecular weight.

Nowhere in the pure spinning the ball through the purification of proteins and hydroxy polymer (PVA) polymer conducted by add initiator, the add-in technology and soybean protein hydroxylation of reach phase stripping copolymer blends, made into a very stable spinning solution.

In order forthe spinning out of wire with fibers of softness, drape, breathable, gloss, moisture resistance and strength, fineness, hold together, spinnability, the key is to select good spinning process.

1991-1993, try wet spinning process, hundreds of times, as a result of the experiment down too slow, use dry.

1994-1995, began to use dry spinning process, but encountered a craft unstable, temperature requirements, spinning solution concentration not good master, at high temperature and high pressure liquid protein in the polypeptide chain reaction prone, acyl ammonia key issues.

1995-1996, test dry spray wet spinning method, but this process equipment manufacture of high precision and more complex, and finally back to wet spinning process.

1996-1997 and went back to wet spinning process.

In 1998, soybean protein fiber development work with breakthrough progress, unlocking some of soybean protein, spherical structure change of protein molecules in space, soybean protein fiber combines chemical fiber import with moist, breathable cotton.
