It is understood that the China General - China textile green fiber project was established in 1998, and the 100 ton line was built in 2005, and the thousand tons line was built in 2009. The 15 thousand ton production line in 2016 was successfully driven at one time, with independent independent intellectual property industrialization technology, complete equipment localization, superior product quality, and mature technology as a whole, reaching the international advanced level.

He Yanli said in his speech that the high quality development and green development of the chemical fiber industry will help to promote the overall development level of the textile industry from the source.

Lyocell fiber is considered to be one of the representative products of green fiber because of its sustainable source of raw materials, closed cycle of production process, excellent wearability and degradation after discarding. For this purpose, Lyocell fiber has become one of the important tasks of promoting the high quality development of the chemical fiber industry and even the textile industry, and is also an important manifestation of satisfying the people's pursuit of a better life.

With the efforts of several generations, China General Textile Research Institute of China has been the second company in the world to have Lyocell fiber independent intellectual property rights industrialization technology. It has further enhanced the ability to serve the national strategy and people's better life needs, and hope that China Textile Institute green fiber joint stock company can provide more green materials for China's textile industry.

According to Liu Jian, China General Textile Co., Ltd. was jointly funded by China General Textile Institute, Xinxiang chemical fiber and blue tech 3 companies in Xinxiang in 2015.

The first phase project invested 560 million in January 2016 broke the ground, and in December 23rd of the same year, the one-time drive was successful.

The two phase of investment was put into operation in 2018, and 800 million yuan was invested in the end of December of the same year. The annual output of 30 thousand tons of new cellulose fiber industrial production line was successfully put into operation. It became the first and second supplier of Lyocell fiber in China. It also completed the industrial plan of the national "13th Five-Year" annual output of 30 thousand tons in 13th Five-Year.

In February 21, 2019, a total of 1 billion 293 million yuan annual output of 60 thousand tons of new solvent method cellulose fiber industrialization project officially started, the construction period of 18 months, will be fully driven in June next year.

At that time, the production scale of Lyocell fiber with an annual output of 100 thousand tons will be formed in Xinxiang, with an annual sales income of up to 2 billion yuan.

At present, the general technology group has launched the pilot reform of the state-owned capital investment company, and the China Textile Institute is also gradually deepening the comprehensive reform of the SASAC's "200 hundred operations". In this historical opportunity, China General Textile Textile Institute strives to build an industrial scale of 500 thousand tons Lyocell per year in the world in 2021, and build an industrial scale of 1 million tons in 2023 to build a world-class high-tech new material industry group.

For China GM - China spinning green fiber project, Zhou Mingchun said, Lyocell fiber is green fiber, and the market prospect is considerable.

The project has completely independent independent intellectual property industrialization technology, and the localization of the complete set of equipment has laid a solid foundation for the group to create an internationally competitive world-class technology and new material industry group.

At present, the general technology group has launched the pilot reform of the state-owned capital investment company, and the China Textile Center is gradually deepening the comprehensive reform of the SASAC's "200 hundred operations". On this basis, the China Textile Institute should reach the industrial scale according to the plan as soon as possible.

He also suggested that pulp is the key factor that restricts the development of green fiber. First of all, we must solve the pulp problem.

Secondly, China textile green fiber project should consider the long-term operation cost of steam, water and so on.

Thematic communication

Indicating the future development direction of the green fiber industry

Sun Yushan, former deputy chief engineer of China Textile Institute, has brought you a special report on "30 thousand tons / year Lyocell (Lesel) fiber domestic complete set of technology and equipment production line".

He said that there are many technical problems in the industrialization of Lyocell fiber, which is recognized as a difficult item in the international fiber industry.

Aiming at the problems of swelling activation, thin film evaporation and dissolving, dry spray wet spinning and low temperature solvent recovery in the process of Lesel fiber industrialization, China Textile Institute has broken through the key technology and equipment, and built an independent Lyocell fiber industrial production system.

Compared with the similar technologies abroad, the national production technology and equipment developed by ourselves are short, low energy consumption and less investment. The investment of 10000 tons of production is about 1/2 of the imported technology. The main performance of the Lyocell fiber product reaches the international advanced level, and 12 invention patents are obtained, and 2 patents are applied for.

Anhui Huamao textile Limited by Share Ltd, vice president of Anhui Huamao textile dyeing and Finishing Technology Research Institute, delivered a keynote speech on the development and application of the xill fiber.

Guan Hui compares the physical properties of Hisel fiber with other regenerated cellulose fibers. She indicates that the dry strength of Hisel fiber is obviously better than that of the international viscose fiber. At the same time, compared with the international mainstream Lesel fiber, Hisel has a comparative advantage in dry strength and dry fracture elongation.

She also focused on the control of the actual application process of hex.

Guan Hui said that the application prospect of xill fiber is very extensive because of its better comfort, low cost, clean and efficient production, and the benefit of human society in resource recycling.

Zhu Junwei, deputy general manager and chief engineer of China Textile Institute (Zhejiang) Technology Research Institute Co., Ltd., based on the discussion of the key technology of dyeing and finishing of Hisel fiber fabric, discussed the development of dyeing and finishing process system, the dyeing and finishing method of fibril dyeing of Hisel fiber fabric, and the fibrillation test method.

He said that the China Textile Institute currently belongs to the standard Lyocell fiber, and its capacity is 30 thousand tons / year. It mainly develops woven fabrics for women's clothing, including dozens of pure shell, Greek / cotton, Greek / hemp, Greek / viscose, Greek / nylon non elastic and elastic fabrics.

Ren Changbang, chairman of Jiangsu mutual Textile Technology Co., Ltd. shared the analysis of Lesel fiber market demand.

The textile industry specializes in domestic fiber imported yarn. In 2018, it sold 18 thousand tons of imported yarn and made a breakthrough of 500 million yuan, accounting for 1/2 of the total market share. Since this year, the company has sold 60~70 tons of domestic products.

The use of textile products covers all kinds of products such as home textiles, jeans, knitwear, dyed fabrics and corduroy.

Ren Chang bang made a prediction on the market application of Lesel yarn in 2019: in 2019, the application direction of Lesel yarn mainly includes the following three aspects: first, the field of jeans, especially the low branch Lesel yarn will increase significantly this year; two is the knitting field, 32 and 40 yarn will also usher in explosive growth; three is the field of white cloth.

Overall, demand will explode in the next 3~5 years.
