As a traditional manufacturing industry in China, how to realize the upgrading and development of the textile industry through automation and digitalization has always been a key issue for the industry.
"In the promotion work, we must adhere to the principle of seeking truth from facts, vigorously strengthen investigation and research, find out the situation of different industries and different enterprises, strengthen the necessity and feasibility analysis of intelligent manufacturing projects, and coordinate and implement policies. We must actively guide and prudently advance, Don't miss the opportunity, don't venture blindly." At the China Textile Industry Intelligent Manufacturing Conference held in Taian, Shandong on June 20th, Gao Yong, secretary of the Party Committee and Secretary General of the China National Textile and Apparel Council, stressed the need to achieve practical results and promote textile intelligent manufacturing. Be steady and far-reaching.
There is still a big gap from the real intelligence requirements.
It is understood that from the current overall situation of the textile industry, equipment automation, digital transformation efforts, equipment networking, real-time production monitoring results are obvious; spinning and chemical fiber filament production line in the past two years can be achieved unattended at night, The unmanned spinning process can be realized; the digitalization and digital processing center of the computerized flat knitting machine and warp knitting equipment drives the overall intelligent level of knitting production; the more automatic control of the production process flow in the printing and dyeing industry and the application of the smart logistics conveying technology The more extensive, the representative digital printing and dyeing factory was initially formed; the whole process automation of non-woven fabrics and the front-end feeding and back-end slitting, winding and packaging automation progressed rapidly; the automation level of garment sewing units was significantly improved, and the sewing process was realized. Hanging, the overall solution for smart clothing manufacturing has matured, large-scale customization and collaborative manufacturing of garments have been developed; intelligent production of home textiles such as towels and bedding products has gradually emerged, and intelligent transport, smart suspension, and intelligent storage have made greater progress. .
The practice of intelligent manufacturing in the textile industry has played an important role in improving production efficiency, improving product quality, accelerating rapid market response, alleviating labor shortages and environmental constraints. However, at present, only automation, digitization, and informationization have been realized, and there is still a big gap between the requirements of true intelligence. Compared with the advanced level in foreign countries, there are still some gaps in China's textile equipment interconnection and data collection, information fusion, intelligent execution, and enterprise intelligent operation in various fields of the textile industry chain. Gao Yong said, "The successful cases of China's textile intelligent manufacturing are mostly demonstration projects in more than 30,000 regulatory groups in China. A few have just started small-scale promotion. Most enterprises still need to make up classes in industry 2.0, 2.5, and 3.0. Therefore, we should have a clear understanding."
In 2017, the China Cotton Textile Industry Association conducted a survey on the development of smart manufacturing in the industry. From the investigation, the development level of smart manufacturing in China's cotton textile industry is in its infancy, and the replacement of old equipment with digital equipment, on-line production monitoring, and integrated management and control are core and bottlenecks. The development stage of intelligent manufacturing in the textile industry determines that the current foundation must be strengthened. In view of the development characteristics of intelligent manufacturing in the textile industry, Cao Xuejun, deputy director of the Consumer Products Industry Department of the Ministry of Industry and Information Technology, put forward four suggestions: The industry should strengthen collaborative innovation, Improve and improve the basic level of smart manufacturing; lay a solid foundation, continue to standardize and improve the smart manufacturing standards system; promote integration, nurture smart manufacturing ecosystem; expand the application, and further enhance the intelligent manufacturing transformation of traditional industries.
Promote changes in manufacturing and service models
Many factors such as labor, difficulty in recruiting, improvement of product quality and efficiency have made enterprises have huge demand for digital network intelligence. Qu Xianming, director of the Manufacturing Research Office of the Chinese Academy of Engineering, believes that the breakthrough of the new generation of artificial intelligence technology and its integration with the manufacturing industry make it possible for intelligent manufacturing to truly achieve "intelligence."
This is clearly a higher level of application beyond the digital phase. According to the three basic paradigms of China's intelligent manufacturing proposed by the Chinese Academy of Engineering: digitization, digital networking, and digital networked intelligence (a new generation of smart manufacturing), in the next 20 years, the development of smart manufacturing in China must adhere to “parallel advancement. The technical route of "integration development".
For the textile industry, this is not only the parallel advancement of the three basic paradigms of smart manufacturing, but also the parallel advancement of traditional production and business models and smart manufacturing models. After summarizing the development path starting from enterprise diagnosis, lean production first, “two-wheel drive” of “smart products and intelligent equipment”, and establishment of a shared factory system, Qu Xianming believes that smart manufacturing in the textile industry needs to lay a solid foundation and grasp Five things: Carry out enterprise intelligent manufacturing transformation diagnosis, train benchmarking companies in various sub-sectors, hold on-site conferences to promote applications, conduct next-generation artificial intelligence technology in the textile industry, train specialized system integrators and establish services. platform.
In order to ensure a steady and long-term development, the integration of smart manufacturing in the textile industry cannot be blindly advanced and needs a clear direction of development. Yu Jianyong, an academician of the Chinese Academy of Engineering and a professor at Donghua University, said that intelligent manufacturing in the textile industry should drive the transformation of the textile manufacturing model, and further promote the transformation of textile service manufacturing and the transformation of green textile manufacturing. In terms of the change in manufacturing mode, traditional textiles must be transformed from a large number of manufacturing modes to automatic production, automatic logistics, automatic warehousing, automatic detection of the few people, unmanned manufacturing model; from the manufacturing criteria based on process criteria to data-driven intelligence. Optimize manufacturing mode; Change from linear manufacturing mode to interconnected networked production mode; From large-scale order-based manufacturing mode to multi-variety, small-batch flexible manufacturing mode, from a single plant operation mode to a distributed collaborative manufacturing operation mode . In terms of changes in service manufacturing, traditional textiles must shift from a production-decision-to-consumption model to a consumption-determined model, abolishing the boundaries between producers and consumers, and promoting textile manufacturing to meet individualized consumer trends. In terms of green manufacturing transformation, traditional textile manufacturing will shift from an unsustainable development model with large resource consumption and large environmental impact to a precisely controlled manufacturing model, achieving sustainable development in energy conservation, environmental protection, and ecological greenness; and shifting from a one-off consumption model of textile products. For the recycling of new models, the green life cycle of textile products is achieved.
Taking an intelligent workshop (factory) as an important breakthrough
The smart workshop (factory) is a major form of smart textile manufacturing at the present stage, and is also the basis for achieving higher levels of smart manufacturing. Gao Yong said that it is necessary to take the smart workshop (factory) as an important breakthrough to grasp and implement the intelligent technology research and development of the production process in key fields such as chemical fiber spinning, spinning, weaving, non-woven, dyeing and finishing, clothing and home textiles. Demonstration, accelerate the construction and popularization of textile intelligent workshops (factories), realize the automation and intelligence of the whole process of textile production process, and promote the transformation and upgrading of the textile industry to a new generation of intelligent manufacturing.
