China's chemical fiber output accounts for more than 70% of the global total output, but the domestic spinning finishes started late. Its advanced preparation technology is still in the hands of developed countries, and its market share is less than 20%. Improving the quality and market share of domestic finishes is the current development focus. Gu Yonghuan, chief technical engineer of the R&D Center of Zhejiang Transchem Chemicals Co., Ltd., focused on the development mode of nylon spinning finishes. From the perspective of functional decomposition, common technology modules, underlying technology logic, etc., he deeply understood the cross field of chemical fiber process finishes, used effective formula design tools, and discussed the new development mode of finishes.

Gu Yonghuan said that there is still much room for the technical development level of domestic spinning finishes, and it is urgent to test the technical capacity of spinning finishes through market practice. Transchem has launched a series of flagship polyester/nylon spinning finishes to the industry, which can increase the market share of domestic finishes through long-term verification by leading customers. In the future, more environment-friendly, functional and differentiated products will be introduced to the market to provide downstream customers with some oil solution.
