The production capacity of Shantou three Hui car is 1000 kg / h when producing the products of 2200 mm to 3300 mm and 600 g / sq m to 2500 g / m2.

Intellectualization: key breakthroughs and gradual progress

With the help of the "intelligent manufacturing pilot demonstration project" and other tasks, textile equipment has been accelerated to intelligent development.

In 2017, ministries and commissions of the national development and Reform Commission, Ministry of industry and technology and Ministry of science and Technology launched special projects to support technological development of enterprises.

In the field of textile and textile machinery, there are many enterprises supporting the scope of national projects. Jiangsu Dasheng Group Co., Ltd.'s "spinning digital workshop pilot demonstration" and the "cotton spinning intelligent factory pilot demonstration" of Anhui Huamao textile Limited by Share Ltd were selected in the Ministry of industry's "Intelligent Manufacturing Pilot demonstration project in 2017"; 4 comprehensive standardization projects such as "research and test validation of the general model standard of warp knitting weaving workshop" in Tianjin University of Technology were selected as the "comprehensive standardization project for intelligent manufacturing in 2017"; 8 projects of "intelligent weaving whole process digital workshop project" of Shaanxi Changling textile machinery and Technology Co., Ltd. were supported by the Ministry of industry's "2017 new pattern application project".

The textile industry in the future will further deepen the popularization and application of intelligent manufacturing, improve the digitalization and intelligentization level of textile equipment, and achieve the upgrading of labor productivity, production flexibility and product quality, and promote the development of the industry to the high-end.

In addition, the China Textile Machinery Association has completed the task of compiling two government research reports, namely, the research on intelligent equipment in textile industry by the national development and Reform Commission, and the research on the target and path of textile intelligent manufacturing in the Ministry of industry and commerce.

The two research reports were completed in July 2017 and May respectively, and the evaluation and acceptance of the two ministries and commissions were carried out.

The report provides advice and suggestions for the government to support the upgrading of the textile industry's industrial structure and support the upgrading of the textile equipment level. In particular, it provides an industrial project with detailed, representative and advanced technology that can be completed in the next 3 years.

The two research report puts forward the necessity and urgency of developing intelligent textile equipment; discusses the trend of technological development and market demand; on the basis of "guiding opinions on development" of textile machinery industry in 13th Five-Year, according to the actual situation of the industry, it puts forward the development principle of "key breakthrough and gradual development".

Standardization: Service

Development

The technological progress of the industry needs to be guided by standards and supported by standards.

According to Li Yi, as of December 31, 2017, the textile machinery industry has 118 national standards, 411 industry standards, and the total number of standards is 529.

The textile machinery standards committee (SAC/TC215) is working on the international standard work of the Standardization Technical Committee of textile machinery and accessories (ISO/TC72) and its 6 sub technical committees.

ISO/TC72 has 148 existing standards, 17 of which belong to the cotton processing Standard Committee and the clothing washing machinery standard committee in the country, and 131 international standards in the field of textile equipment.

At present, 108 international standards have been pformed into China's standards, with a conversion rate of 85.7%.

In 2017, the NSAC promulgated the 1 national standards for textile machinery and accessories: fifteenth part of textile machinery terminology: compact spinning device, which is the first basic national standard independently formulated by the textile machinery industry.

In 2017, the Ministry of industry and Commerce promulgated 32 industrial standards in the field of textile machinery and accessories, 2 were the basic general standards, 1 were methods standards, 29 were product standards, 12 of which were newly formulated standards, and 20 were revised standards.

Li Yi said, it is worth mentioning that the construction of the standardization system of textile industry intelligent manufacturing is progressing smoothly.

In accordance with the requirements of the national guidelines for the construction of intelligent manufacturing standards system, under the guidance of relevant departments of Ministry of industry and the China Electronic Technology Standardization Institute, the China Textile Machinery Association has begun to organize the related work of intelligent manufacturing standardization in the textile industry relying on the National Standardization Committee of textile machinery and accessories. It represents the industry to participate in the revision of the guide for the construction of the national intelligent manufacturing standard system, and participates in the strategic consultation project of the Chinese Academy of engineering, the research on the development strategy of Intelligent Manufacturing in China's textile industry and its sub topic "common technology and standards for textile intelligent manufacturing".

In 2017, 4 integrated standardization projects were selected in the textile industry.

In addition to the project "basic standard research and test validation for large-scale customization application in garment industry", led by Qingdao cool special stock company, the remaining 3 are organized by the China Textile Machinery Association. They are the project of "standard and test verification of general information model for intelligent control and management of high end knitted fabrics" organized by Fujian Baikai warp knitting industry Co., Ltd., the project led by Tianjin University of Technology to study and verify the general model standard of warp knitting weaving workshop. The project of "interoperability and interoperability standard research and verification" between the dyeing and finishing intelligent equipment and manufacturing system, led by Hangzhou Kaiyuan computer technology Co., Ltd., means that the standardization work of the intelligent manufacturing factory (workshop) in textile industry has been carried out in an all-round way.
