The preparation process is green and environmentally friendly, and solvent is harmless and harmless. It is the national key development of bio based fiber and the main direction of the transformation and upgrading of the regenerated cellulose fiber industry. We will further promote the innovative development of new solvent based regenerated cellulose fibers (Lesel fibers), strengthen cooperation and exchanges between fiber and downstream enterprises, and speed up the process of new products, new technologies, new formats, new mode innovation and demonstration application and popularization of new solvent based regenerated cellulose fiber (Lesel fiber), and promote the construction and development of textile circular economy. This has become an important way for China's textile industry to carry out green development.

Zhao Xuchun, mayor of Shouguang City People's government, said that in recent years, the city has been developing high quality industries and constantly strengthened the Daxin material industry. The industries involved in the industry accounted for more than 60% of the new material classification of the national industrial strategic emerging industries, and initially formed a new material industry system mainly based on advanced polymers, new water proof biological foundations and light buildings. By the end of 2018, the city's new material enterprises above Designated Size reached 70, and the main business income was 17 billion 300 million yuan. Next, the city will take this opportunity as an opportunity to further speed up the development of the bio based fiber industry in, promote the docking of the new solvent based regenerated cellulose fiber industry with the upstream and downstream industry chain, upgrade the technological level of the regenerated cellulose fiber in the chemical fiber industry, accelerate the upgrading of the textile industry, and strive to build a National Bio based new material industry cluster, and strive to achieve 40 billion yuan in the main business of the new material industry in 2022.

In October 26, 2018, the Shandong Provincial People's government issued the special plan for the development of new material industry in Shandong Province, focusing on developing functional fiber products such as regenerated polyester fibers, dyed fibers of raw liquor, conductive fibers, graphene modified fibers and flame retardant fibers. The industrialization process of degradable and renewable biomass fibers such as chitin fiber, seaweed fiber, hemp fiber, polylactic acid fiber, flame retardant and high wet modulus regenerated cellulose fibers was accelerated. The integrated development of functional fibers and intelligent textiles such as temperature regulation and conduction was strengthened. A series of major strategic plans were made to break through the industrialization technology of green pulping and pulp and fiber integration, the preparation of special cellulose pulp for new solvent method, and the key technology of industrialization of "dissolving spinning solvent recovery". Wang Zhaochun, an inspector of the Shandong provincial Ministry of industry and commerce, said to speed up my efforts.

In 2015, after 6 years of deep cooperation between industry, University and Research Institute, Yingli company in our province broke through the technical problem of large-scale manufacturing of regenerated cellulose fiber by new solvent method, breaking the monopoly of international fiber giants on our market for many years, filling the gaps in the domestic market, and successfully realizing the transformation of research and manufacture of regenerated cellulose fibers made from domestic new solvent method from "watching running", "running away" to "running" and "leading" in some fields, which has brought great opportunities for the development of advanced textile materials and related industries in our province. Up to now, Yingli company has applied for 12 new invention patents, 48 utility models and 48 patents in new solvent method, and the total amount of patent authorization ranks first among domestic counterparts, ranking second in the world, behind Lenzing Co in Austria. The project of "research and development of key technologies of cellulose fiber by 10000 ton new solvent method" has been awarded by the Yingli company of Hebei Province. It has won the first prize of textile science and technology progress of Textile Industry Federation of China in 2016 and the first prize of science and technology progress in Shandong in 2017.

High quality development

Gao Yong, secretary and Secretary General of the China Textile Industry Federation, said that fiber materials, as the source of the development of the textile industry chain, will play an important role in promoting the sustainable development of the textile industry and even the whole society. Statistics show that in 2018, the world's chemical fiber production was more than 7000 tons, and China's chemical fiber production was 50 million 300 thousand tons. China's chemical fiber production and China's chemical fiber usage were 70% of the world. New solvent method cellulose fiber (Lyocell) is a kind of green and regenerated cellulose fiber. Donghua University, Shandong University, Shandong Yingli, China Heng Tian Baoding swan, China Textile Science Research Institute, Xinxiang chemical fiber and other research institutes and enterprises, through cooperation in production, teaching and research, break through the core intellectual property barriers, from R & D, technology, engineering to industrialization. This "textile light" new solvent method to regenerate cellulose fiber key technology and application of scientific and technological achievements promotion is a concrete action to carry out green development and promote the sustainable development of the textile industry. It will definitely enhance the production of new cellulosic fiber technology and equipment in China, and make positive contributions to the structural adjustment of China's textile industry, the transformation and upgrading of regenerated cellulose fiber industry, and the green manufacturing of textile fiber raw materials.

In the middle and late 13th Five-Year, we hope that Chinese textile enterprises will accelerate the process of green development closely combined with the guidance of the national industrial policy, strengthen independent innovation and create their own brands. We must give full play to local resources and technological advantages, grasp the trend of demand, and strive to build a textile industrial cluster with Chinese characteristics and international competitiveness. We should continue to increase the awareness of green manufacturing and green development, enhance consumers' understanding of green fiber, and further build a platform for face-to-face learning and communication, joint product development and application promotion for the upstream and downstream of the textile industry chain, and advocate the concept of green and low carbon consumption.

At the meeting, textile science and Technology Education Foundation awarded donation certificates to Yingli Industrial Co., Ltd., Shandong.

President Li Lingshen, vice chairman of Shandong textile and garment industry association, Bobby Chan, Professor Yu Yongming, vice chairman of Qiingdao University, Qian Xiaoming, Tianjin University of Technology Han Ronghuan, chairman of Shandong Yingli Industry Co., Ltd., Han Ronghuan East, Dezhou general manager of Hengfeng Textile Co., Ltd., chief engineer of Shandong Huaxing Textile Group Co., Ltd., chief engineer of Shandong Ruyi Cotton Textile Group Co., Ltd., director of production, director of technology center of Binzhou Oriental carpet Co., Ltd. and other relevant leaders, industry experts and enterprise representatives, focusing on building up new investment solvent and regenerated cellulose fiber (fiber) industrial technology, production ecological chain, high quality development investment and policy environment, and conducted a high-end interview at the event site, which has solved a lot of problems about fiber technology and application for the participants. Jiang Shicheng was also invited by the Chinese Academy of engineering, vice president of China Textile Industry Federation and China Industrial Textiles Association.

Professor Li Faxue of Donghua University introduced the technological innovation of Lesel fiber in detail. He said that in recent years, through the in-depth study of China Textile Institute, Xinxiang chemical fiber, Baoding swan, Shandong Yingli and colleges and universities, the processing technology of our country's lycel fiber has been more mature, but there still exist certain problems in large-scale integrated production, such as dissolution, solvent recovery, fibrillation, operation and quality stability. Under the circumstances of commercialization abroad and basically 10000 tons of Engineering in China, it is necessary to further break through the key technology and equipment to build Lesel (Lyocell) fiber industrialization system.

Professor Xia Yanzhi of Qiingdao University has introduced the development of flame-retardant products of framer, non fibrinolytic fiber and antibiotic products, and the industrialization of multifunctional and differentiated series. At present, the production of traditional viscose fiber in China is about 5 million tons / year. Due to the serious pollution of the production process, the state has been more and more severely restricted. Lyocell fiber has become the best substitute for traditional viscose fiber because of its cleaner production and use process. If we can overcome the key technology of Lyocell fiber functionalization, break the monopoly of foreign technology, promote the large-scale production of functional Lyocell fiber, expand the application field of Lyocell fiber, drive the upgrading of domestic green textile raw materials and transform the old and new kinetic energy of the traditional textile industry. It is estimated that by 2025, the domestic Lyocell fiber production capacity will reach 1 million tons, forming an annual output value of 25 billion yuan, leading to the downstream of the new fiber textile and textile machinery industry more than 300 billion yuan.

In the afternoon, Cai Xiaoping, executive vice president of Shandong textile and garment industry association, chaired.

Qian Xiaoming, a professor at Tianjin University of Technology, shares the application of Lesel fiber in nonwovens from the deep meaning of regenerated cellulose fiber, the application status of regenerated cellulose fiber in nonwovens, and the innovative methods of regenerated cellulosic fiber nonwovens. He said that from the raw material to the production process, product performance and application areas and the use of the final product, every step of the new melt blown nonwoven process is superior to the traditional melt blown process.

Ren Changbang, chairman of Jiangsu mutual Textile Technology Co., Ltd. made a detailed analysis of the demand for the market and technology development of the new solvent based regenerated cellulose fiber. In 2016~2018, the application of Lesel yarn in the field of jeans has always occupied half of the market. This is because the market development of Lesel yarn in jeans field is relatively perfect, and the downstream users have wide acceptance. At the same time, there has been a large increase in knitted and white embryo areas, mainly because the Lesel yarn used in knitting field is superior to cotton yarn and modal yarn strength, handle and luster. Through years of data accumulation, it can be predicted that the development direction of Lesel yarn in 2019 mainly includes the following three aspects: first, the Lesel yarn in the jeans field, especially the low count Lesel yarn in the field of jeans, will increase significantly in 2019; two, the Lesel yarn in the knitting field, 32 and 40 yarn will also usher in explosive growth; three is the white embryo cloth field, and the sales of 21*21 and 30*30 white germ cloth will reach a new high this year.

Zhang Hongmei, chief engineer of Shandong Ruyi cotton spinning group company, shared the development and application technology of Lesel fiber in the field of fabric. She said that the fiber has many excellent properties of natural fiber and synthetic fiber. Its gloss is natural, its handle is smooth, its strength is high, its shrinkage rate is small, its moisture absorption and permeability are good, soft and comfortable, smooth and cool, and its drapability is good. It originates from ecological plants, fiber processing technology follows the principle of environmental protection, and fiber can be biodegraded to nature. It is a green and sustainable environmental protection fiber, and fiber as the source of the development of textile industry, environmentally friendly fiber can be said to be the guiding sign of sustainable fashion industry.

Gao Hongguo, manager of cheerful Home Textile Co., Ltd., made a professional sharing on the development and application technology of Lesel fiber in home textiles, especially the printing and dyeing technology of Lesel fiber fabrics.

Chen An, director of production technology of Binzhou Oriental carpet Co., Ltd., said that with the development of the times, people's consumption concept has also undergone great changes, especially for green and environment-friendly ideas. Apart from the consumption habits which are difficult to change by a few ethnic minorities, most consumer groups have changed to varying degrees. The number of chemical fibers based on bio based chemicals, coloured chemical fibers from raw liquids and carpets with recycled chemical fibers as pile materials are increasing year by year. For the first time, the company has developed a carpet with Tencel as its pile material. After being washed by water (Tang Guang), the product has been popular with consumers because of its good gloss and its market.

The promotion activities on that day were echoed by the enthusiasm of the participants. They agreed that the emerging technology in textile industry, especially the technological innovation in green development, is a practical action to carry out the new orientation of "technology, fashion and green" in the textile industry, and also the only way for China's textile industry to grow from big to strong.
