Preparation Technology And Equipment Of Wuhan Spinning Large Nanofiber Membrane Through Identification

The key technology and equipment development of the controllable thermoplastic polymer nanofiber membrane, jointly undertaken by Wuhan Textile University and Kunshan Hui Wei new material Co., Ltd., has been appraise through the project. The appraisal committee composed of 7 experts, Professor Jiang Shicheng and Professor Cheng Po Wen, inspected the production site of the new Wei Wei new material Co., Ltd. and observed the samples. After that, he heard the Research Report of Professor Wang Dong, the project leader, and reviewed the project appraisal. Material Science 。

After questioning and appraising, the appraisal committee believed that the project innovated the new method of preparing nanofibers, expanded the application field of nanofibers and successfully applied them, and had broad prospects for application and popularization. The overall technology of the project has reached the international advanced level, and the key technology has reached the international advanced level.

It is understood that polymer nanofibers have unique advantages such as small diameter, large surface area, high porosity and light weight. They have broad application prospects in many fields such as water purification, air rate, industrial (medical) protective clothing, lithium ion battery separator, biosensor and energy. However, the existing Nanofiber membrane Low production efficiency has become a bottleneck restricting its large-scale industrialization application.

　　 Wuhan The textile university has worked closely with Kunshan Hui Wei new material Co., Ltd. for 9 years, and independently developed the key technologies for large-scale preparation of thermoplastic polymer nanofiber membranes. In Kunshan, the first large-scale production line of thermoplastic polymer nanofiber membrane has been designed and built in China, and the large-scale preparation of controllable thermoplastic polymer nanofiber membrane has been realized. It has been successfully applied to the field of water purification, and has carried out a lot of research work in air filtration, protein separation and biosensors, with remarkable results.

The reporter has learned that although China's textile industry has made remarkable progress in science and technology in recent years, and has led to industrial innovation and development, China's textile industry's independent innovation capability is still relatively weak. It needs to accelerate the development of the textile industry in the high-end, sustainable development, high-end and high-tech textiles innovative design and development, advanced textile processing technology, ecological dyeing and finishing technology, and application of electronic, information, automation technology to upgrade and upgrade the textile industry.

"Textile industry is a pillar industry of China's national economy, an important livelihood industry, and an obvious component of the industry and strategic emerging industries with international competitive advantages." Yu Jianyong, academician of the Chinese Academy of Engineering in an interview with the media, said that the scope of strategic emerging industries should include new fiber materials, new industrial textiles, ecological dyeing and finishing, advanced textile equipment, and textile industry informatization. In the future, China should increase investment in technological innovation of new textiles and promote transformation and upgrading of textile industry.

According to media reports, at present, China's textile industry related technological innovation support system is still very incomplete. In this regard, Yu Jianyong believes that at present, the most short board in the textile industry is the state-level key laboratories and engineering centers which are responsible for the basic application of common key technologies and industrialization of achievements. In the future, relevant departments of the state should pay attention to the layout and perfect the National Textile Science and technology innovation research and development base.

At present, textile enterprises have evolved from OEM, customer demand, and pure processing to gradually enrich the products by selecting innovative design elements, and provide more abundant products for customers to choose. Some enterprises are developing towards brand direction, deepening international cooperation and expanding cooperation space.

The industry believes that optimizing the ability of product design has become an important way for enterprises to open up the textile market. The diversification of the Chinese market enhances the awareness of independent design of the brand, which provides fertile ground for the growth of the designer. With the development of the market, the demand for the design of local enterprises and brands is becoming more and more obvious. People's demand for product's optimization design is increasing. Brand and consumers pay more and more attention to quality. They pursue individuality and style, and the connotation of products themselves. From the industry point of view, the professional design personnel of over more than 200 textile and garment design institutes meet the needs of the textile industry for design talents every year. On the other hand, domestic textile enterprises are actively carrying out substantive cooperation with foreign professional design institutes to rapidly improve the design level of textile products.

In addition, it is an inevitable trend to promote the development of textile technology with the combination of collaborative innovation and various new technologies. Yu Jianyong said that the technological innovation of the textile industry should not only realize the collaborative innovation in the industry chain, but also realize the multi-disciplinary and cross industry collaborative innovation. "China's textile industry must implement the strategy of innovation driven development, further enhance the contribution rate of technological progress to industrial development, and speed up the textile industry's ecological, green, low-carbon, digital and intelligent development to further expand the emerging industries, and further promote the textile industry to meet and meet the needs of the country's economic and social development." Yu Jianyong said.
