Automation, Information Technology, Digitalization And Networking Of Intelligent Manufacturing Of Nonwovens Are Important.

In June 23rd, the China Nonwovens Intelligent Manufacturing Conference and the disposable hygiene products development forum were held in Foshan, Guangdong. Gao Yong, secretary and Secretary General of the China Textile Industry Federation, vice president of China Textile Industry Federation, Li Lingshen, President of China Industrial Textiles Association, Sun Jinliang, academician of Chinese Academy of engineering, Li Ping, director of Industry Coordination Division of national development and Reform Commission, and more than 100 participants.

Li Lingshen said at the meeting that the development of new technology has changed the format of traditional manufacturing industries. As an important part of Intelligent Manufacturing in textile industry, a number of backbone enterprises have actively implemented intelligent manufacturing, launched new technology concepts and production methods, and built up a new production mode of automation, informatization, digitalization and networking, which has promoted the production efficiency and production value of the industry. The development of Intelligent Manufacturing in nonwoven industry should focus on 5 key words: truth-seeking, intelligent manufacturing can only achieve effective development only based on a realistic attitude; the key is to break through the common key technologies in related fields to realize the foundation of intelligent manufacturing; value, intelligent manufacturing should not only solve the problem of labor shortage, but also create the value of the whole industrial chain; data, intelligent manufacturing requires more data collection, data analysis and data application; and the development of intelligent manufacturing requires more professionals with professional skills.

For the development of intelligent manufacturing of industrial textiles and nonwoven industry, Li Lingshen made 3 suggestions. First, we should actively develop and spanform the industry's intelligent manufacturing. On the basis of informatization, strengthening the cultivation and diagnosis of industries and related enterprises will be the focus of the next step. The two is to train professional information service providers and set up an industry public service platform to drive and lead the development of the demonstration industry. Three, we should set up benchmarking and pilot demonstration enterprises, increase application and promotion efforts, strengthen visits among enterprises, and share the experience of intelligent manufacturing.

Tao Xiaoming, a professor at Hong Kong Polytech University, made a report entitled "opportunities and challenges for intelligent manufacturing and intelligent textiles". According to him, intelligent textile is a collection device of functional fibers with sensing, servo, communication, easy to adapt, self repair, self supply energy and learning. It can respond to the external excitation according to the program, and has nano or sub micron structure on the surface and middle of micron level fiber to realize its function. Smart textiles are characterized by flexibility, large deformation, real-time, and long-term wear. The fabrication process of fiber based electronic devices includes two ways: directly conductive fibers or yarns to be directly implanted into textiles, wearable electronic devices, and wearable flexible electronic devices made by surface coating, screen printing or surface self-assembly technology. Smart textile electronic devices show superior comfort, cleanliness, durability and fatigue resistance in the field of wearable and industrial textiles. The flexible wearable system composed of intelligent textile devices has shown great potential in some applications. However, due to the limitations of the manufacturing process, the surface structure of wearable electronic devices or fabrics is limited to micro and nano scale. Scale mismatch largely restricts its application in traditional integrated process, and it still needs to grasp the common key technologies through deep penetration of basic science, applied science and technology research.

Zhu Duoxian, a researcher at the Institute of intelligent research, introduced how to build an intelligent factory centered on quality and efficiency. He said that intelligent manufacturing has become the global trend of development. The people-centered "human-computer network triple strategy" is highly consistent with the production concept of excellence. It emphasizes that it is not simply automation, but emphasizes human value. It is an effective way for intelligent manufacturing to control dumb intelligence and develop intelligent manufacturing. We must adhere to the idea of intelligent planning, intelligent decision support, intelligent quality control, intelligent resource management, intelligent interoperability and intelligent collaborative production "six dimensional intelligence". We should take quality improvement and efficiency as the core, optimize production plan, improve planning balance, ensure overall efficiency improvement, ensure warehouse lean, reduce backlog, reduce material cost and waste, coordinate process, take equipment as the core, reduce equipment auxiliary time, advance preparation, and coordinate production.

Gao Jinrui, executive deputy general manager of Hunan Zhongnan Intelligent Equipment Co., Ltd. made a report entitled "intelligent equipment boosts the intelligent manufacturing and upgrading of non-woven fabrics". He said that at present, mass customization has become the main mode of production of intelligent manufacturing products, and has the advantage of effective combination of mass production and customized production. The "robot + industry" structure model can focus on industry solutions, and pursue standardization and standardization from design, planning, production to service process, and create industry benchmarks. For example, in the precision production field of automobile engine cylinder block, cylinder head, crankshaft and other core components, a number of intelligent cleaning equipment for robot cleaning have been developed, which can accurately remove burrs and debris after machining, and improve the assembly accuracy and cleanliness of the engine. The perfect combination of robot technology and nonwovens conveying packaging is a necessary way to achieve a series of functions such as automatic winding, handling, wrapping, labeling, stacking and other functions in the production process. In particular, the use of three-dimensional storage mode has effectively solved the shortcomings of large storage and wide storage in the nonwovens industry, and has also made good statistical scheduling and control of different types of products to achieve the full process management of factory materials. Zhongnan intelligent joint China Textile Union and SIEMENS, relying on the company's engineering experience in the field of intelligent manufacturing for many years, has systematically made diagnostic consultation, solution, intelligent manufacturing personnel training, intelligent manufacturing equipment upgrading for non-woven enterprises.

Jiang Manxia, consultant of China pulp and paper research institute, introduced the general situation and trend of domestic hygiene products market. She said that at present, the market of domestic hygienic products has been growing steadily, the market competition has become more intense, the advantages of big brands have been weakened, the market structure has been fragmented, the trend of high-end consumption, the full implementation of the two child policy and the intensification of aging have brought new opportunities for the sanitary products industry, attracting a new round of investment expansion, and multinational companies continue to increase imports of ultra high end products in order to maintain their competitiveness in the Chinese market. In addition, the changes in the market pattern and the price of raw materials compress the profit space, force the enterprise to develop innovation, upgrade and reduce consumption, a batch of competitive enterprises stand out, and the micro business brands rise, and some enterprises have begun to develop and distribute to the overseas markets in various ways. As a whole, domestic health products will continue to develop in close proximity, breathability and personalization. Turning to the trend of domestic sanitary products industry, she said that the overall growth rate of domestic disposable health products slowed down, but baby diapers, adult incontinence products and wipes products will continue to maintain a two digit growth in the next 5 years. The strong demand in the Chinese market has also prompted Japan to grow in the urine pants business.

Deng Weitian, deputy general manager of Foshan Nanhai Bi De Fu nonwovens Co., Ltd. The development of spunbonded nonwovens for high performance hygienic materials is introduced. The current spinning and melting nonwovens of the company Material Science Annual capacity of 78 thousand tons, widely used in health materials, medical consumables, industrial areas.
