Animal And Plant Wastes Pform Into New Textile Materials

Protein synthetic fiber is a new material developed from natural animal and plant protein. Because its quality is like silk and cashmere, its raw material resources are abundant. Animal milk dregs, casein, hair and vegetable soybean cake can be used as raw materials and have wide application scope.

Henan Puyang Tianyuan protein fiber company has undergone 10 years of painstaking research and development from protein fiber research to pilot production to industrial production.

8 patents in 10 years

With the improvement of living standards, people are increasingly advocating nature, pursuit of comfort, health care and beauty, so natural fiber is favored by consumers.

However, the yield of natural fiber is restricted by many factors. Sheep are limited by grassland, and the development of silk is constrained by planting mulberry and labor.

Can we invent a new material similar to natural protein fiber? In order to achieve this dream, Germany, Britain, the United States, Japan and other countries have gone through more than a century of exploration. By the 70s of last century, Toyo Textile Co., Ltd. Japan developed New Zealand milk as raw material, and acrylonitrile grafted copolymer protein fiber, became the world's first industrialized production of protein fiber manufacturers.

However, due to the shortage of raw materials and the high cost, the capacity has not been expanded for more than 30 years.

Speaking of the hardships of R & D, Zhuo Baosong, the chairman of the company, said: "first, we do not have enough research funds to spend money on our own preparation. Secondly, there is a lack of professional talents. Protein synthetic fiber involves three major technological fields: biology, chemical engineering and textile. We are all" outsiders ". Thirdly, there is no experimental apparatus, and the molecular weight, molecular structure and amino acid sequence of protein can not be determined.

But we have persistent belief and perseverance, that is, on the one hand, we have built up a small pilot plant on the basis of self-knowledge of Biophysics, polymer chemistry and fiber technology.

After more than 100 small experiments, we have gradually grasped the cutting-edge technologies such as extraction methods of animal and plant protein.

In the end, the company learned from foreign experience and lessons, combined with China's national conditions, in line with the principle of using waste, saving resources and environmental protection, went through 10 years of research and went through many hardships and spent 12 million yuan. Finally, the research of protein fiber was successful.

According to Zhuo Baosong, later, the company set up a pilot plant. It joined hands with 10 scientific research institutions and 19 experts and professors. After more than 400 medium scale experiments, it successfully developed protein fiber and obtained 7 national invention patents and 1 utility models patents.

In October 2007, the project of Puyang Tianyuan protein fiber company invested 400 million yuan, covering an area of 13 square meters, and started construction in the gathering area.

The project is planned for 6 production lines with an annual production capacity of 15 thousand tons.

The whole project is divided into three phases.

At present, 100 million yuan has been invested in the first phase, and an annual production line of 2500 tons of protein fiber has been built.

The two phase of the annual production of 12500 tons of protein fiber project will start construction in the first half of next year.

Turning waste into treasure

New material is superior in quality and low in cost.

Entering the company's large and commodious production workshop, reporters saw that all kinds of canisters were lined up, pipelines were densely packed, and the equipment was arranged in an orderly way.

According to the technical personnel of the company, protein fiber is made from animal and plant waste as raw material, and the spinning solution is made by grafting and copolymerization of macromolecular polymers with the denaturation and dissociation of protein macromolecules, and side chain modification. Then, the whole process of protein fiber production is completed through 6 processes, namely, raw liquid spinning heat treatment aldehyde treatment dyeing finishing package.

Zhuo Baosong said that as a key project in Puyang, the city leaders and relevant departments attached great importance to the project, and repeatedly went to the scene to understand the progress of the project and coordinate the settlement of the problem.

In the company's product exhibition room, all kinds of protein fiber textiles are dazzling.

Here, protein fiber fabrics are colorful; protein fiber knitted underwear, sweater, novelty and unique; protein fiber blankets, light and thick and soft; protein fiber wig, false.

This fiber has the luster of silk, the softness of cashmere, the strength of chemical fiber, and its fabric is noble and magnificent.

Ma Quanming, director and senior engineer of the company's product development center, told reporters: "this protein synthetic fiber is inexhaustible and inexhaustible as raw materials from animal milk residue, casein, waste hair, dandruff and plant soybean cake, peanut cake, rapeseed cake and other wastes.

Protein fiber not only turns agricultural and animal by-products into treasure, but also costs less than 20% of Japanese milk protein fiber.

The characteristics of new protein synthetic fiber products are also very obvious: first, it can be blended well with cotton, wool, linen, silk, chemical fiber and other kinds of fibers to achieve industrial upgrading; two, it is good in dyeing properties, suitable for dyes, and is active, acidic and neutral dyes, and it has strong color fastness, strong color fastness, dyeing, printing and jacquard. It can disperse fiber dyeing and yarn dyeing or dyeing. Three, it has good physical properties, high strength, breathability, moisture absorption, quick drying and skin care. Four, it has wide application scope, and can be used for knitted underwear, woolen sweater clothing, bedspread, quilt cover, bath towel, blanket and other household textiles and wig.

Ma Quanming is proud to say that the protein fiber products produced by the company have been awarded the title of "Millennium gold medal" issued by World Expo and the United Nations Organization in Shanghai.

At the same time, when the first phase of the project was completed, the company also held a cooperation ceremony with Henan Institute of Engineering.
