Introduction: At present, the world economic structure is in a period of deep adjustment. At the same time, a new round of technological revolution and industrial transformation are accelerating. The superposition effect is obvious. On the one hand, the disciplinary breakthroughs and cross-integration trends have become increasingly evident. Groups such as information networks, biotechnology, clean energy, new materials and intelligent manufacturing have shown a leap forward in the areas of continuous development of new industries, new models and new formats. On the other hand, Major countries in the world are speeding up the layout of new industries and new formats. By stepping up investment in scientific and technological innovation, they are making full use of the scientific and technological revolution and industrial transformation opportunities to speed up the cultivation of new kinetic energy so as to seize the commanding height of future economic and industrial competition. Relevant research shows that from now till 2040, it will be a crucial period for the birth and development of the new science and technology revolution, bringing about profound changes in the world's development pattern.
"Intelligent" is undoubtedly one of the high-frequency hot words in the past two years, mainly covering three major sections of smart products, smart equipment and intelligent operation. Among them, the equipment is the foundation, operation is the core, and the product is the direction. Below we will focus on the production and product areas of some intelligent cases.
Intelligent production
At present, intelligence has applications in various subdivisions of textiles. Such as: Polyester staple post-processing joint machine by the DC motor drag the long axis to the motor DC common bus frequency control speed Division drive; Cotton spinning production line from the card to the fine network, the thickness of the network, and the thickness of the network, Workshop management system; jet loom weft insertion automatic analysis of automatic correction; knitting workshop equipment interoperability;
Cotton spinning intelligent workshop
Jiangnan University and Jingwei Yuci jointly developed three-color smart spinning technology, by feeding three different colors of roving at the same time, through the coupling draft, mixed twist and change the ratio of the three primary colors and change the yarn color, you can spin Any color of yarn, yarn and yarn to achieve the synchronization of color, and the configuration of the intelligent operation.
Three primary colors intelligent spinning technology
Knitting equipment, intelligent technology research and promote the use of further enhance the international competitiveness of the knitting industry. Based on machine vision fault detection technology online, yarn-feeding intelligent control technology, CAM integrated control system to promote the intelligent development of knitting equipment, improve production efficiency and product quality; knit intelligent design system, knit simulation system, knitwear The application of virtual display technology further enhances the design level of knitted products and adapts to the trend of individualization, customization and fast fashion. The combination of online real-time data collection technology and big data mining technology establishes the knit product quality data mining model, For the enterprise's product quality management to provide pre-control mechanism.
Intelligent application in knitting production
In the future, the textile industry will speed up the development and service provision of intelligent technologies and equipment, push forward the combination of technologies such as sensing, communication and artificial intelligence with textile technologies, extensively promote equipment intelligence in all aspects of the textile value chain, and build intelligent filaments Production lines, intelligent spinning production line, intelligent printing and dyeing production line, intelligent non-woven fabric production line, intelligent knitting production line, intelligent clothing textile production line, to enhance the quality and efficiency of production; step by step building intelligent manufacturing demonstration production lines and digital factories to create Textile industry intelligent manufacturing ecosystem.
Intelligent Manufacturing is an advanced manufacturing system that integrates technological innovation, pattern innovation and organizational innovation. It is a combination of many advanced manufacturing systems and models such as integrated manufacturing, lean manufacturing, agile manufacturing, virtual manufacturing and networked manufacturing. Broadly speaking, intelligent manufacturing is a big concept. It is a deep integration of advanced manufacturing technology and next-generation information technology. It runs through all aspects of product, manufacturing and service lifecycle and manufacturing system integration. Automation, information and networking are fundamental prerequisites.
Like "innovation", "smart manufacturing" also has the phenomenon of misunderstanding and even over-consumption. From a realistic point of view, most enterprises in our country, especially large and medium-sized enterprises, have not yet completed the digital manufacturing transformation at this stage, and digitalization is the foundation of intelligent manufacturing. Therefore, for a period of time to come, large-scale promotion and full application of digital networked manufacturing will be the focus of our country's efforts to promote intelligent manufacturing.
Smart product
The traditional smart textiles (or electronic textiles) based on the combination of electronic components and textiles can not be washed due to the presence of electronic components or need to be disassembled during washing, and will affect the wearing comfort and appearance aesthetics, while the smart textiles based on flexible textiles Electronic components can be fully integrated with textiles. Textile electronic components based on fabric, embroidery and digital printing, which have been developed in recent years, can be used as data storage, sensors and energy storage devices.
NASA's nanotechnology experts have developed a prototype of a flexible electronic textile that stores data like a storage disk. With a data storage point at each interlacing point of the fabric, 1GB of data can be stored for 115 days. Theory Allows the use of any form of interactive tools, such as computers to give users feedback. Forster Rohner, one of Switzerland's leading embroidery laces, uses conductive yarns to develop an electronic textile based on an embroidered textile sensor that is not only washable and does not affect the properties of the fabric, it can be used to monitor the health of patients or special populations.
In addition, in view of the technical defects of ordinary battery technology in battery life, washing, shape design flexibility and so on, the power supply equipment based on flexible textile materials has also become a hot spot in the field of smart textiles.
Nazmul Karim at the University of Manchester, UK, invented a low-cost, flexible textile supercapacitor that was printed on cotton fabric using simple screen printing techniques and graphene oxide ink, with excellent mechanical stability and good handling Security, the battery itself also supports fast charging, allowing washing.
In October 2017, Felice Torrisi and others at the Graphene Center at the University of Cambridge published in Nature Communications the results of their first study of successfully printing electronic circuits on fabrics using ink-jet printing technology. Using low graphene and other two-dimensional materials Boiling-point inks Printed electronic circuits on polyester fabrics can withstand up to 20 home-style washes and optimize circuit performance by improving the fabric's surface roughness. The researchers said printed electronics made from other inks are not suitable for wearing on printed materials that normally require toxic solvents and that the method is based on a low-cost, safe, environmentally-friendly ink that can be used for wearable energy harvesting and storage Equipment, wearable computers, military apparel and fashion apparel.
