"Accumulation spinning device" industry standard passed certification

The project followed the standard-setting procedure and adhered to current laws, regulations, and mandatory standards. All submitted documents were complete and formatted in compliance with the required guidelines. The "Agglomeration Spinning Device," which meets the domestic advanced level, was recently approved as a recommended textile industry standard—specifically, the compact spinning yarn device. This milestone took place in Changzhou, Jiangsu Province. The certification meeting for the "Agglomeration Spinning Device" textile industry standard was chaired by the Technical Committee for Standardization of Spinning and Dyeing and Finishing Machinery under the National Textile Machinery and Accessories Standardization Technical Committee. The meeting unanimously approved the standard. The working group is now tasked with incorporating feedback from the meeting, revising the document accordingly, and submitting it through the proper channels for final approval and publication within the textile industry. According to industry experts, agglomeration spinning represents an innovative spinning technology. Chinese textile professionals have continuously improved upon foreign advanced technologies through digestion and absorption. Today, they have successfully achieved mass production and application of agglomeration spinning devices that are characterized by Chinese features and independent intellectual property. These devices have become a key method for enhancing the quality of ring-spun yarn. In line with the requirements of the National Development and Reform Commission’s Industry Office [2006] No. 1093, the Jiangsu Wuxi Textile Machinery Research Institute was assigned the responsibility of developing the textile industry standard for the "Agglomeration Spinning Device." Determining the yarn quality criteria for agglomeration spinning in the standard to suit China's national conditions and meet user needs is crucial for the development of this standard. First, based on the newly released F/T 12018-2009 "Composed Cotton Tight Yarn" standard, the standard outlines specific yarn quality requirements for combed cotton yarns. It also incorporates assessment indicators based on the evaluation of yarn quality from older machines, ensuring the standard remains advanced, practical, and easy to implement. Secondly, the "requirements" section of this standard includes comprehensive quality specifications for vacuum-type agglomeration spinning devices, as well as key technical requirements that differ from those of traditional ring spinning machine components. Particular emphasis is placed on the importance of the negative pressure system. The standard sets control requirements for component quality, especially for the negative pressure fan, which plays a critical role in ensuring the overall quality of the agglomeration spinning device. Additionally, it includes quality requirements for key parts of China's mechanical agglomeration spinning machines. Thirdly, during the "Industrial Standards Symposium for Agglomeration Spinning Devices," delegates ultimately decided that the scope of this standard should be limited to agglomeration spinning devices and not include the entire machine. However, in the upcoming revision of the cotton spinning ring spinning machine industry standard, the agglomeration spinning process will be included as an important part of the revision. Therefore, it can be said that this standard development has laid a solid foundation for the revision of the cotton spinning ring spinning machine standard and has created favorable conditions for improving the technical level of China's cotton spinning ring spinning machines.
