Newly added "two members" in the technical achievements team of the nylon industry

From June 7th to 8th, China Textile Industry Federation's science and technology guiding project “Cold-denier nylon 6 monofilament and split-fiber mother-spinning one-step high-speed spinning key technology and equipment” and “Nylon 6 intelligent high-efficiency production and three-dimensional storage system The "Integration Technology" appraisal will be held in Fuzhou, Fujian Province.

At the meeting, the two scientific and technological achievements were approved by the expert group. The participating experts agreed that the process technology route developed by the two projects is advanced and reliable, the product quality is stable, the technology is innovative, and the overall technology has reached the international advanced level. At the same time, the expert group made recommendations, and then we must further develop the market and strengthen the application.

“The key technology and equipment for high-speed spinning of coarse-denier nylon 6 monofilament and split-fiber mother-spinning one-step method” is undertaken by Changshen Hengshen Hefei Technology Co., Ltd., Changle Liheng Nylon Technology Co., Ltd. and Donghua University .

It is reported that the current production route for the production of coarse denier nylon 6 monofilament and split fibril has a one-step method and a two-step method. The two-step production process and technology are relatively mature, but the spinning speed is low and the single machine output is low. The UDY wire can be stored for a short period of time and has high humidity requirements for balance and storage environment. The one-step process can complete the spinning process, the priming fiber drawing orientation, the fiber heat setting and the winding process on the same machine, and has the advantages of short process, high production efficiency and low energy consumption.

The R&D team of the project conducted in-depth research on the key technologies and related equipment for further high-speed spinning of coarse-denier nylon 6 monofilament and split-fiber mother yarn. For the project's objectives and tasks, the coarse-denier nylon 6 monofilament and split-fiber mother wire A large amount of research work has been carried out on key technologies, key equipment and spinning dynamics simulation of industrial production, and the research results have been scaled up in Hengshen Hefei Technology Co., Ltd. and Liheng Jinlun Technology Co., Ltd.

The project has broken through the key technical bottlenecks of efficient and stable production of coarse-denier nylon 6 monofilament and split-fiber mother yarn, realized high-quality and high-efficiency large-scale production, and has low energy consumption and low cost, and achieved remarkable economic and social benefits. 6 Industry upgrades and upgrading of international competitiveness will play a good role in promoting.

“Jinlun 6 intelligent and efficient production and three-dimensional storage system integration technology” is jointly undertaken by Fujian Jingfeng Technology Co., Ltd. and Hunan Normal University. After years of hard work, the project has integrated deep groove long diameter ratio screw, single set double cavity, rare earth composite material insulation, drafting and winding integration, automatic winding, automatic conveying, online sorting, automatic packaging, three-dimensional storage, etc. Technology, the realization of the entire process of intelligent production. At the same time, the project has established a nylon 6, intelligent, high-efficiency production and three-dimensional storage system with an annual output of 200,000 tons. It has stable operation, excellent product quality, high production rate, low energy consumption, high production efficiency, and good economic benefits. Social benefits. It is understood that the project has independent intellectual property rights and has authorized 10 utility model patents.
