Recently, the mid-term inspection meeting of the national special R & D plan "Key Basic Materials Technology Enhancement and Industrialization", a key special item, "High-performance polyester and polyamide 66 industrial yarn preparation technology" project was held in Shaoxing, Zhejiang. The conference was organized by the High-Tech Research and Development Center of the Ministry of Science and Technology. Specialized experts from the overall expert group, peer experts, and management experts, as well as the main members of the project team, attended the meeting. The key special management of "Key Basic Materials Technology Upgrade and Industrialization" Relevant personnel of the Office (hereinafter referred to as "Special Office") attended the meeting.
At the meeting, the person in charge of the special office introduced the basis, purpose and process of the inspection. The expert team conducted a site inspection of the project participant Zhejiang Guxiandao Green Fiber Co., Ltd. and heard the project leader's mid-term implementation of the project's overall progress, personnel and funding input, supporting conditions for the project, and organization and management. report. After full discussion and inquiry, the expert group agreed that the project has achieved the expected work goals, and put forward clear opinions and constructive suggestions.
On the basis of clarifying the mechanism of falling film melt polycondensation reaction of high viscosity polyester and revealing the falling film flow characteristics of high viscosity polymer, a new type of polyester falling film melt polycondensation reaction technology and equipment was developed, and small and medium tests were conducted. An industrial production test was carried out, and a professional application index detection method for polyester industrial yarn was established. For the high-performance polyamide 66 industrial yarn, a demonstration production line of 10,000-ton airbag yarn has been established to achieve continuous and stable production of polyamide 66 industrial yarn, which has promoted the use of high-performance polyester and polyamide 66 industrial yarn in the fields of automotive, marine, and construction. High value applications.
