本土纺织行业推动智能制造向高端绿色发展/Local textile industry promotes smart manufacturing to high-end green development
As a traditional pillar industry and an important civilian production industry, the textile industry is in a critical period of transformation and upgrading. The entire industry faces real problems such as the disappearance of demographic dividends, rising raw material prices, increased environmental pressures, and reduced exports. Facing the development dilemma, the textile industry is actively seeking change, using intelligent manufacturing as a means to open up the data flow of the textile industry chain and the key links of production and manufacturing, to carry out the transformation of production mode and business model, and to realize the labor productivity and flexibility of the textile industry. Improvement, as well as improvement in product quality and resource energy consumption, promote the development of China's textile industry to the high end.
Supply Chain Collaboration Improves Resource Allocation Efficiency
China's textile and garment industry has a low overall market concentration, mainly for small and medium-sized enterprises. The information docking between upstream and downstream is not smooth enough, and it is generally faced with problems such as financing difficulties and inventory backlog. Looking for gauze network as a starting point for supply chain finance, establishing a B2B e-commerce platform, providing free matching transactions to yarn manufacturers and demanding enterprises, and using the transaction data accumulated by the company on the platform to provide credit guarantees to help enterprises obtain banks. Loans from financial institutions.
Looking for gauze to profit from the commission of the loan service, and the yarn company solved the problem of capital turnover by means of the platform. As the industry leader, Jiaxin Silk is also building Internet-based supply chain financial services. Silk products have obvious seasonal characteristics, and it is necessary to stock raw materials during the drying period of silkworm cocoons, and small and medium-sized manufacturers are often unable to adequately stock up due to shortage of funds. Jiaxin Silk has built a professional trading platform “China Silk Trading Market” and established cooperation with banks to allow small and medium-sized enterprises on the platform to obtain loans from silk raw materials as collateral. This model not only effectively solves the financing problems of SMEs. It also better integrates supply chain resources.
Intelligent equipment supports green development
Under the background of rising labor costs, upgrading the digital and intelligent technology level of textile equipment has become an important means for the textile industry to improve labor productivity and product quality stability. Anhui Huamao Textile Co., Ltd. and Jingwei Textile Machinery jointly developed the cleaning and carding equipment to realize the continuous and automatic production of the two processes of cleaning cotton and carding, and adopting the domestically developed foreign fiber automatic sorting instrument to open the pine. The cotton stream is scanned in all directions, and the foreign fibers such as chemical fibers and plastic films in the cotton stream are removed. Jiangsu Dasheng has established a digital spinning workshop, equipped with an intelligent logistics delivery system, based on automatic guided trolleys and robots to complete logistics, palletizing and packaging work, reducing the number of million ingots from 50 to 20, and greatly increasing labor productivity. With the increasingly strict environmental regulations and related standards, green development has become the guiding concept of the textile printing and dyeing industry. The waterless printing machine developed by Zhejiang Shaoxing Dongsheng Digital directly prints dyes and additives onto the fabric by computer control. No noise, waste water and exhaust gas are generated during the printing process. The intelligent printing and dyeing products developed by Jiangsu Changzhou Hongda Group can detect the water consumption, sewage and exhaust emissions during the production process, effectively reducing pollution emissions and resource consumption.
Online testing and feedback optimization textile process
In the yarn dyeing process, in order to ensure the accurate operation of the process parameters, it is necessary to detect the temperature, dye liquid level and other indicators in real time in order to adjust the production process. Luthai Textile has established an on-line detection and feedback system for dyeing process. A temperature sensor is installed on the dyeing machine. According to the real-time temperature on-line detection and the adjustment of the pneumatic valve positioner, the dyeing temperature is constant. A differential pressure level gauge is installed in the master cylinder of the dyeing unit to detect the dye liquid level in real time and serve as a basis for adjusting the opening size of the pipeline valve to achieve precise control of the liquid level.
Through on-line inspection, the dye sample product has been greatly improved in one-time sample rate and production efficiency. During the weaving process, there may be some flaws in the cloth due to mechanical failure or operational errors. Textile companies have traditionally used manual methods for fabric flaw detection, which is not ideal for detection accuracy, speed and detection rate. Jiangsu Wuxi Xinjie has developed a “warp machine cloth online visual inspection system” based on machine vision to realize real-time detection of cloth defects in warp knitting machine weaving process.
Large-scale personalized customization to enhance user experience
Under the pattern of overcapacity, the traditional textile and garment production model generally suffers from serious inventory problems. Zhejiang Ningbo Cixing has built a knitwear flexible custom platform “weaving and wearing”, allowing consumers to customize the size of the sweater and customize the pattern at a specific location.
Cixing has established a consumer membership database to collect and organize human body size data and personalized design data, and upload it to the cloud platform to provide version support for personalized customization. Through the 3D scanning system, more than 80 body information data can be collected in 5 seconds, which significantly improves the efficiency and accuracy of the volume link. The volume data is sent to the intelligent knitting equipment independently developed by Cixing, which can quickly complete the customized production of single or small batches, and deliver them within 7 days, and the price is lower than the same retail price of the same paragraph.
It can be seen that the personalized customization realizes the flat and light inventory of the sales and distribution channels, which greatly improves the operational efficiency of the knitted sweater industry chain.
Four major initiatives to promote smart manufacturing in the textile industry
Intelligent manufacturing is an important starting point for the transformation and upgrading of the textile industry. The textile industry can start from four aspects and further accelerate the advancement of smart manufacturing:
The first is to promote the development and application of intelligent textile equipment. Textile equipment is the basis for the intelligent manufacturing of the textile industry and the integration of the new generation of information technology and textile technology. The industrial application of intelligent textile equipment is the key to improving production efficiency and product quality. We should make full use of the existing funding channels to support enterprises in the development and promotion of new spinning and weaving equipment, new printing and dyeing equipment.
The second is to give full play to the driving role of the pilot demonstration. The Ministry of Industry and Information Technology has carried out the pilot demonstration of intelligent manufacturing for two consecutive years. A number of advanced models have emerged in the textile industry, such as the “Pilot Dyeing Smart Factory Pilot Demonstration” of Shandong Kangpinna Group and the “Crafting Intelligent Flexible Customization Platform Pilot Demonstration of Ningbo Keat” "Where, the successful experience and technology of leading companies should be fully summarized and promoted in the whole industry, thus driving the overall improvement of the intelligent level of the textile industry.
The third is to build a team of intelligent manufacturing talents in the textile industry. Strengthen the training of intelligent manufacturing talents in the textile industry, train a group of compound talents with both textile industry knowledge and intelligent manufacturing technology, and a group of high-quality professional talents who are good at intelligent equipment and system operation. Explore diverse talent training mechanisms and encourage textile companies to collaborate with universities to develop smart manufacturing talents.
