< p > Sheng Hong group and Tsinghua University jointly developed the bio diesel by-product glycerol as the main raw material to produce high performance biomass fiber project, and broke ground in Zhen Ze town, Suzhou, Jiangsu Province in May 5th.

After the project is put into operation, Sheng Hong will become the second company in the world to produce this product with a complete industrial chain. It will break the monopoly of pnational giants and open up the upstream and downstream of the chemical fiber industry, so that the development of China's chemical fiber will reach the world's advanced level.

Miu Hangen, chairman of Sheng Hong group, said that the landing of Suzhen biological project provided a good opportunity for the domestic chemical fiber industry to cultivate new industries and spawn new growth points, and will become the new trend of leading the development of chemical fiber industry.

< p > PTT fiber as a new type of fiber in the world, it combines the softness of nylon, the fluffiness of acrylic fiber, the antifouling property of polyester and the resilience of spandex. It integrates all kinds of chemical fiber's excellent properties and is called "memory fiber". It is one of the most popular polymer materials in the international market at present.

Because of the difficulty in synthesizing PTT polyester raw material, the technology threshold and safety threshold are very high, showing an oligopoly pattern.

In 2012, Sheng Hong group independently developed, designed and had complete intellectual property rights. China's first annual production of 30 thousand tons of PTT polymerization device was successfully launched, breaking the monopoly of multinational companies for a long time to the core technology of the industry.

< p > as the key raw material of PTT polyester, at present, the production of 1, 3- propylene glycol (PDO) is still blank in China. It has been monopolized by international chemical giants and has been in short supply in the long run.

Tsinghua University has applied for a series of patents in the first place in China to produce PDO by using bio diesel by-product glycerin fermentation. Core patent applications have been authorized by more than 10 countries, including the United States.

The technology, which uses biomass feedstock and extracted from renewable biomass materials, is in line with the current trend of low carbon environmental protection and renewable resources in the world. It has been included in the key support area of the national "12th Five-Year plan".

More importantly, this achievement is considered to be China's closest breakthrough in the world. It is a "green project" characterized by biotechnology. It indicates that the world's largest producer of chemical fiber has embarked on the path of green development, and has an inestimable impact on the world textile a href= "http:// m.pmae.cn/" target= "_blank" and "clothing /a" industry.

Before P, Sheng Hong group had conquered PTT fiber spinning technology, PTT polyester synthesis technology, memory fiber dyeing and other technical difficulties.

After the project is put into operation, it will quickly form the localization technology of PTT industry chain, and form PDO production, PTT synthesis, PTT spinning, PTT fabric printing and dyeing technology and industrialization.

Zhang Yun, general manager of Suzhou Suzhen bioengineering Limited by Share Ltd, said that chemical fiber is an important raw material source for the textile and garment industry, affecting the design and production of downstream enterprises. P

Vigorously developing recycled fiber and biologically based fibers can not only realize the sustainable development of the industry, but also provide more room for pformation and upgrading for the entire textile and garment industry. The development of green biomass materials and fibers based on bioengineering technology can partly replace traditional petrochemical processes, and will become the new trend of leading the development of "a href=" //m.pmae.cn/news/index_c.asp "chemical fiber industry" /a.
