  • Detail

During the "Eleventh Five Year Plan" period of the textile industry, significant achievements have been made in tackling key scientific and technological problems and promoting the industrialization of achievements. Since the "Eleventh Five Year Plan", China's textile industry has taken accelerating scientific and technological progress as an important support to promote the adjustment of industrial structure and industrial upgrading, and has actively carried out a number of work around the improvement of innovation ability and the upgrading of technical equipment. At the end of 2004, the China Textile Industry Association formulated and issued the outline for the development of scientific and technological progress in the textile industry, proposing "28 key technologies and 10 new complete sets of key equipment" (referred to as "28+10") that need to be solved urgently in the industry, which were refined and revised twice in 2006 and 2008. In recent years, the industry has carried out a lot of scientific and technological research and industrialization promotion of achievements around the "28+10", and achieved remarkable results

technological upgrading promotes the improvement of industrial efficiency

China's textile machinery industry entered a period of rapid development during the "Eleventh Five Year Plan", during which enterprises have increased the intensity of technological transformation and industrial upgrading. In recent years, through technology introduction, digestion and absorption, textile machinery products have achieved remarkable results in high speed, high performance, high quality, continuity, automation, informatization and other aspects, and the technical level has been significantly improved. The overall process technology and equipment level of the whole industry has been rapidly improved, the investment in advanced technology and equipment has been increasing, and the backward process, technology and equipment are responsible for the faults caused by the shortcomings of design, manufacturing, process or materials under the action of the market mechanism. The technical quality and production efficiency of the industry have been steadily improved

during the "Eleventh Five Year Plan" period, the textile industry introduced nearly 20billion US dollars of foreign advanced equipment and about 280billion yuan of domestic advanced equipment; The chemical fiber industry eliminated about 3million tons of obsolete small polyester equipment, eliminated about 1.5 million tons of backward drawing capacity, and basically eliminated 74 type dyeing and finishing equipment in the printing and dyeing industry. At present, the technology and equipment of about one-third of the key enterprises in the whole industry have generally reached the international advanced level, and the labor productivity of all enterprises above designated size has doubled compared with 2005

in the field of chemical fiber equipment, with the characteristics of large capacity, high starting point and low cost, domestically produced new polyester and supporting long and short filament technical equipment with international competitiveness have been widely used in the industry. At present, it is comprehensively upgrading to the direction of super large-scale, flexible and measurable secant elastic modulus under strain, precision, energy conservation and emission reduction, and a new generation of direct spinning polyester technology, The scale of the whole set has been expanded from the original introduction of 60000 tons/year to 400000 tons/year, and the million ton new PTA complete set of domestic technology and equipment has also been successfully developed. Chemical fiber machinery such as a complete polyester plant with an annual output of 200000 tons and a complete polyester staple fiber plant with a daily output of 200 tons have been industrialized. The localization of technical equipment makes the industry to a large extent determine the use of this kind of plastic and rubber. The investment cost of new projects has been greatly reduced, and the production efficiency has been greatly improved, which has effectively promoted the rapid development of the chemical fiber industry and the optimization and adjustment of the industrial structure

with the continuous improvement of industrial technology during the Eleventh Five Year Plan period, China's cotton spinning complete sets and other equipment have reached the international level of the 1990s. Among them, the blowing carding combine accounts for 70% of the total domestic market, the comber and the segment drive suspension roving machine are close to the international advanced level, and the electromechanical rapier loom has been successfully introduced to the market and recognized by users

in addition, knitting machinery such as computerized flat knitting machine and high-speed warp knitting machine have also been industrialized. The research and development and industrialization of energy-saving and environmental friendly dyeing and finishing machinery in printing and dyeing machinery have achieved results. Nonwoven machinery has also made remarkable achievements in technology application and new product development

outstanding progress has been made in the research and development and industrialization of 10 new complete sets of key equipment identified in the outline for the development of scientific and technological progress in the textile industry since the "Eleventh Five Year Plan". High capacity polyester staple fiber complete sets of equipment, new blowing carding combine, automatic winder and other efficient modern cotton spinning production lines, electromechanical integrated air jet, rapier looms have achieved mass production, some products have reached the international advanced level, effectively replacing imports, and the localization rate of domestic chemical fiber and cotton spinning equipment has been significantly improved. Spunbonded, melt blown, spunlaced nonwovens and knitting equipment such as computerized jacquard circular weft knitting machine, computerized automatic flat knitting machine and high-speed tricot warp knitting machine have been successfully developed and brought to the market, greatly reducing the equipment cost of textile enterprises. The detection and control technology of printing and dyeing process parameters has completed the detection of process points, and the monitoring and closed-loop control system of single machine has also been successfully developed and entered the promotion stage. In the field of printing and dyeing equipment, especially in the era of electric vehicles, a large number of new products with energy-saving, water-saving and emission reduction potential have been developed. Domestic pretreatment equipment and continuous dyeing equipment can replace imports

the electromechanical integration of textile machinery products has developed in the direction of deep-seated intelligence, modularization, networking and systematization. Energy saving technology has been popularized and applied in textile single machines and complete sets of equipment. The new concepts of energy conservation, consumption reduction and emission reduction have been implemented in the design of printing and dyeing and chemical fiber machinery. The engineering system integration technology with an annual output of 45000 tons of viscose staple fiber independently developed by China has reached the international advanced level of the world's highest single track production capacity and the lowest raw material consumption. The technological progress of domestic digital printing equipment has made important contributions to the energy conservation and emission reduction of printing and dyeing and garment enterprises and the enhancement of product added value

make up for the gap between progressiveness and reliability of equipment

although domestic textile machinery equipment has achieved rapid development during the "Eleventh Five Year Plan", there are still many deficiencies that need to be improved during the "Twelfth Five Year Plan". Compared with foreign advanced level, domestic textile machinery products have a significant gap in reliability. Although some domestic textile machinery is relatively advanced in performance, its reliability is not high and cannot be accepted by users. In addition, the gap between China's textile equipment field and the world's advanced level is mainly reflected in automation, continuity, informatization and intelligence. Some high-end textile machinery products such as differentiation, energy conservation and consumption reduction still rely on imports; The production level of special parts and supporting parts is not high, and the stability of the whole machine product is poor. In 2008, the import value of auxiliary devices and spare parts was US $400million, accounting for 40% of the total domestic demand for textile machinery parts

in addition, the combination of equipment manufacturing R & D and production process innovation in China is not close enough, and there is still a gap between product progressiveness and manufacturing level. The independent research and development of high-end equipment still needs to accelerate breakthroughs. The complete production lines of high-performance fibers such as carbon fiber and aramid fiber are still blank in China. High frequency and high-speed needling, high-speed hot rolling, wet forming, two-component spunbonded and melt blown nonwovens still rely on imports, and the coarse and fine combination and fine connection systems have not yet entered the stage of large-scale industrialization. The textile machines independently developed and produced are still insufficient in terms of automation, continuity, informatization and intelligence, as well as the reliability of the whole machine. The operating speed of shuttleless looms is about 10% lower than that of imported equipment. Computerized automatic knitting equipment still needs to be improved in terms of operating speed, fabric quality, knitting control system, etc

the next five to ten years will be a critical period for China's textile industry to comprehensively sprint towards the goal of becoming a powerful country. Accelerating scientific and technological progress, realizing the leap forward development of Textile Scientific and technological productivity, and taking this as a support to change the development mode, is the fundamental way to achieve the goal of becoming a powerful country in textile industry by 2020. In order to achieve the goal of becoming a powerful textile country, the textile machinery industry should continue to strengthen the promotion of reliability, study the reliability allocation principles and methods, failure modes and criteria of major textile machinery products, and the allocation and calculation methods of reliability system indicators, formulate the "textile machinery reliability measurement test and evaluation specification", establish a unified and reliable index evaluation system, and through five to ten years of efforts, Make the reliability index of major textile machinery products reach or approach the international advanced level
