Yueda Textile Group's key technology for the production of jet vortex spinning cotton high count yarn

Shanghai Securities News on May 26, China National Textile and Apparel Council held a scientific and technological achievements appraisal meeting in Yancheng, Jiangsu Province. The key technologies and applications of jet vortex spinning cotton high-count yarn production jointly undertaken by Yueda Textile Group and Jiangnan University The project passed the identification of scientific and technological achievements.

The experts of the appraisal committee listened to the project report, reviewed the relevant materials, also inspected the production site, and watched the samples. After the inquiry and discussion, they believed that the overall technology of the project reached the international advanced level and agreed to pass the appraisal. At the scene, Dai Jun, general manager of Yueda Textile Group, delivered a speech, Liu Biying, executive deputy general manager of Yueda Cotton Textile Company, Fan Qiguang, chief information technology officer of Yueda Textile Group, and Fu Jiajia, associate professor of Jiangnan University, on behalf of the project team for work report, technical report and technology. Reports such as new search, quality inspection, and user use.

It is reported that the appraisal meeting was presided over by Feng Li, Director of the Science and Technology Innovation Department of the Science and Technology Development Department of the China National Textile and Apparel Council. The expert committee lineup was luxurious and authoritative experts were present at the event. Sun Jinliang, academician of the Chinese Academy of Engineering of Shanghai University, and Zhu Beina, president of the China Cotton Textile Industry Association, Du Weiping, professor-level senior engineer of Dongfang International (Group) Co., Ltd., Li Lanling, professor of Donghua University, Ren Jiazhi, professor of Zhongyuan Institute of Technology, Zhao Zhihua, researcher-level senior engineer of Dasheng Group Co., Ltd., and Lv Libin, professor of Yancheng Institute of Technology.

According to reports, in order to expand the application of cotton fiber in jet vortex spinning, Yueda Textile Group and Jiangnan University selected the project “Key Technology and Application of Jet Vortex Spinning Cotton High-count Yarn Production” as a research topic in 2015. The project focused on key technical issues in the production of jet vortex spinning cotton high-count yarns, and original innovation and integrated innovation in jet vortex spinning equipment. Through equipment improvement, component development and process optimization, the key technical difficulties in the production of jet vortex spinning cotton high-count yarns were overcome, and the pure cotton fibers were stably twisted and continuously yarn-forming under the action of jet vortex.

The project realized the development and industrialization of pure cotton jet vortex spinning yarn with a fineness of 7.3tex (80S), broke through the bottleneck of jet vortex spinning cotton high-count yarn production, has innovative and independent intellectual property rights , and has applied for a patent. 6 pieces, including 3 invention patents and 1 utility model patent; 6 papers were published, including 1 SCI and EI. At the same time, the jet vortex spinning cotton high-count yarn developed by the project has less hairiness, smooth and wear-resisting performance, and is especially suitable for high-end children's wear, sweaters, shirts and other end products. The added value of the products is high, and the economic and social benefits are remarkable.

Also attending the appraisal meeting was Wu Zhenzhen, senior engineer of the Science and Technology Development Department of the China National Textile and Apparel Council, Gao Weidong, former vice president and professor of Jiangnan University, Ren Musu, professor of the School of Materials Science and Engineering, Shanghai University, and Liu Guiqi, director of the Yandu District Science and Technology Bureau. Yueda Textile Group, Jiangnan University and other related personnel.
