Intelligent: key breakthroughs, step by step
With the tasks of “Intelligent Manufacturing Pilot Demonstration Projectâ€, textile equipment has accelerated its development towards intelligence. In 2017, several ministries and commissions of the National Development and Reform Commission, the Ministry of Industry and Information Technology and the Ministry of Science and Technology launched a special project to support the technological development of enterprises. In the textile and textile machinery field, many companies have been selected by the national project support; Jiangsu Dasheng Group Co., Ltd.'s “Spinning Digital Workshop Pilot Demonstration†and Anhui Huamao Textile Co., Ltd. “Mianfang Textile Smart Factory Pilot Demonstration†and other 7 enterprise projects Selected by the Ministry of Industry and Information Technology as “2017 Smart Manufacturing Pilot Demonstration Projectâ€; Tianjin Industrial University's “Comprehensive Research and Experimental Verification of General Model Standards for Weaving Digital Workshops†and other four comprehensive standardization projects were selected for “2017 Intelligent Manufacturing Integrated Standardization†project; Eight projects including “Intelligent Weaving Full Process Digital Workshop Project†of Ling Textile Electromechanical Technology Co., Ltd. were supported by the “New Model Application Project 2017†of the Ministry of Industry and Information Technology.
With the advancement of smart manufacturing related technologies in the textile field, the textile industry has evolved from the intelligence of stand-alone machines to the digitization, automation and intelligence of systems. In the future, the textile industry will further deepen the promotion and application of smart manufacturing, improve the digitalization and intelligence level of textile equipment, realize the industrial labor productivity, production flexibility, product quality improvement, and promote the industry to the high-end development.
In addition, the China Textile Machinery Association completed the task of preparing the two government research reports, namely the “Research on the Intelligent Equipment of the Textile Industry†by the National Development and Reform Commission and the “Study on the Implementation Objectives and Paths of Textile Intelligent Manufacturing†by the Ministry of Industry and Information Technology. The two research reports were completed in July and May 2017, respectively, and passed the review and acceptance of the two ministries. The report provides advice and suggestions for the government to support the industrial restructuring of the textile industry and support the improvement of the level of textile equipment. In particular, it provides industrialized projects with detailed, representative and technologically advanced technologies that can be completed in the next three years. The two research reports put forward the necessity and urgency of developing intelligent textile equipment; discussed the development trend of the technology and market demand; based on the "Guidelines for the Development of the 13th Five-Year Plan for Textile Machinery Industry", based on the actual situation of the industry The situation supplemented the development principle of “key breakthrough, step by stepâ€.
Standardization: service industry development
Technological advances in the industry need to be guided by standards and supported by standards.
According to Li Yi, as of December 31, 2017, there are 118 national standards in the textile machinery industry, and there are 411 industry standards, with a total of 529 standards.
The Textile Machinery Standardization Committee (SAC/TC215) works with the International Standardization Technical Committee of Textile Machinery and Accessories Standardization (ISO/TC72) and its six subcommittees. There are 148 existing standards of ISO/TC72, of which 17 are classified into the Cotton Processing Standardization Committee and the Garment Washing Machinery Standardization Committee in China, and the international standard in the field of textile equipment is 131 items. At present, 108 international standards have been converted into Chinese standards with a conversion rate of 85.7%.
In 2017, the National Standards Committee promulgated and implemented the National Standard for Textile Machinery and Accessories, “Textile Machinery Terminology Part 15: Concentrated Spinning Equipmentâ€, which is the first national standard independently formulated by the textile machinery industry. In 2017, the Ministry of Industry and Information Technology issued 32 industry standards for textile machinery and accessories. Two of them are basic general standards, one is method standard, and 29 are product standards. Among them, 12 are newly-developed standards, and 20 are revised standards.
Li Yi said that it is worth mentioning that the construction of the standardization system for intelligent manufacturing in the textile industry is progressing smoothly. In accordance with the requirements of the National Intelligent Manufacturing Standards System Construction Guide, under the guidance of the Ministry of Industry and Information Technology and the China Electronics Technology Standardization Institute and other relevant departments, the China Textile Machinery Association has started to organize intelligent manufacturing in the textile industry relying on the National Textile Machinery and Accessories Standardization Technical Committee. Standardization related work, on behalf of the industry to participate in the revision of the "National Intelligent Manufacturing Standards System Construction Guide", and participate in the China Academy of Engineering strategic consulting project "China's textile industry intelligent manufacturing development strategy research" and its sub-project "Textile Smart Manufacturing Common Technology and Standards "Research. In the 2017 Intelligent Manufacturing Integrated Standardization and New Model Application Project, four comprehensive standardization projects were selected in the textile industry. In addition to the “Basic Standardization and Experimental Verification of Large-scale Personalized Customization Application for the Apparel Industry†led by Qingdao Kuote Intelligent Co., Ltd., the other three projects are organized by China Textile Machinery Association, respectively. Industrial Co., Ltd. led the "High-end Knitted Fabric Production Intelligent Control Model Common Information Model Standard and Test Verification" project, Tianjin University of Technology led the "Research and Experimental Verification of General Model Standards for Weaving Digital Workshops", Hangzhou Open Source Computer Technology Co., Ltd.
