05 denier filaments. It can produce antibacterial, far-infrared, anti-static, conductive, flame-retardant, moisture-absorbing, anti-ultraviolet and other functional fibers by blending and modifying various additives. High-performance fibers such as aramid, carbon fiber and ultra-high molecular weight polyethylene have become indispensable new materials for aerospace, energy, construction, protection, filtration, automotive, marine, agriculture, animal husbandry and fishery, as well as entertainment, sports and other industrial sectors. The industrial production of new fibers such as solvent-based cellulose fibers and polylactic acid fibers is considered to be an environmentally-friendly textile raw material for the sustainable development of the textile industry in the 21st century. Different fiber raw materials are mixed, compounded, deformed, woven, printed and dyed, and post-finished, and the shortcomings and complementary advantages are produced to produce a wide variety of textiles. With the continuous development of chemical fiber varieties, the blending and interweaving of various fiber raw materials has become a new trend in the development of textile production and textile dyeing and finishing technology.

International textile technology continues to develop in the direction of quality, high yield, automation and continuity. The developed countries are led by electronic information technology, based on new materials and high-precision automated machining technology, using light, machine, electricity, pneumatic, hydraulic and other sensing technologies to develop new generations of modern equipment and realize textiles. On-line detection, display, automatic control and automatic adjustment of various process parameters in the production process, automatic monitoring, display and even automatic elimination of equipment operation status are realized. The highly automated production equipment can strictly follow the set process requirements, and realize the simple and repeated manual operation in the traditional textile production relying on the technical proficiency of the workers in the qualitative, quantitative and standardized mechanical actions to ensure and improve the product quality. Increased production efficiency, reduced product costs, and enhanced product competitiveness.

Taking cotton textile production as an example, the carding technology that has been widely used in developed countries has eliminated the impact of the traditional opening and cleaning process on the quality of the sliver.

New technologies and new technologies such as large-capacity cotton pile blending, reciprocating automatic cotton picking, multi-tank blending, and cotton box blending have improved the process of opening, removing, homogenizing and mixing, and improving the process performance. The photoelectric detection, pressure sensing, airflow cotton feeding, autoleveling, and computer integrated monitoring technologies adopted in the single machine and the whole process improve the stability and reliability of the whole process, ensuring continuous, synchronous and smooth operation of the whole process. The uniformity of the output sliver.

In-line automatic detection and removal device for heterosexual fibers developed in recent years, using color digital camera technology, can accurately determine the size and position of foreign fibers through surface scanning, compensation, calculation, correction of illuminance difference, spectral analysis, etc., sprayed by one or more nozzles The high velocity airflow discharges the foreign fibers.

The self-adjustment of the card and the strip is stabilized by the techniques of on-line detection, displacement sensing, signal conversion, servo system control, computer processing, frequency conversion speed regulation, etc., so that the uniformity of long segments, super long segments or short segments of the output sliver can be stabilized. Within a certain range, the stability of the yarn quality is ensured.

The roving frame adopts multi-motor sub-step variable frequency drive and servo control technology, which greatly simplifies the mechanical transmission system. The CCD tension fine adjustment technology can precisely control the spinning tension, ensure the roving tension is constant, and improve the spinning quality.

The continuous automatic improvement of the overall automatic doffing and automatic winding air splicing technology of the spun yarn long-term has made the fine-stitched spinning technology enter the practical stage in the mid-1980s. The direct connection of the two processes with the most people and the strongest labor intensity in cotton spinning not only guarantees and mentions the product quality, greatly reduces the employment, improves the labor productivity, and also solves the long-term difficulty in solving the spinning production. The contradiction between the spinning speed and the spun yarn package greatly increases the spindle speed of the ring spinning machine.

The calculation method of physical labor productivity of cotton spinning enterprises formulated in the mid-1980s once stipulated that 282 people used to produce 20-inch yarns for cotton spinning, and most of the cotton spinning mills in China still stay at this level, and the international tens of thousands of chains 30- There is a big gap in the level of 60 people. With new processes, new technologies, new equipment and necessary improvements in production management and labor organization, the number of users will be reduced to around 100. If the fine-linking process is further adopted, the number of users should be reduced to 6 or even less.

Weaving is still dominated by shuttle looms in China, which is an important factor restricting the international competitiveness of cotton and post-processing products in China. International shuttleless weaving technology has developed rapidly and mechatronics has reached a very high level. Computer technology is widely used in parameter setting, production process control and auxiliary design of loom. By inputting the relevant parameters into the computer, the loom can change the fabric type according to the set requirements. Through various sensors, the production process can be monitored, displayed and controlled, used for automatic selection, control of weft density, automatic weft insertion, automatic joint, automatic transfer, self-stop control, positioning vehicle, mis-correction, control of loom Start, brake, etc. The display shows the operation of the loom in real time and communicates with the host computer in both directions. Computer technology guarantees the high quality, high yield and rapid replacement of fabrics. Computer technology is also commonly used in fabric-assisted design and mechanical design and manufacture of loom.

Post-dyeing and finishing has always been a weak link in China's textile industry and an important factor restricting the quality, variety and competitiveness of China's textile products. The quality of traditional printing and dyeing finishing production mainly depends on mature technical procedures, strict operation management, skilled workers' skills and work responsibility to ensure “process on the car”; modern printing and dyeing finishing production mainly relies on extensive use of electronic information technology. Leading new technologies, new technologies and new equipment. Various process parameters such as temperature, concentration, pressure, speed, etc. during scouring, rinsing, dyeing, printing, drying, setting, etc. can be detected online by various sensors, and the steam pressure and drying temperature are automatically adjusted by computer processing. The speed of the fabric reaches the set process requirements, thus ensuring and improving the quality of the product. Automated auxiliary facilities such as automatic color measurement, automatic color separation, automatic color matching, and automatic pulping ensure the stability, consistency, and reproducibility of product quality.

Dyeing and finishing production has adopted new technologies to further improve product quality or meet environmental protection and energy saving requirements. Some progress has been made, and some have begun to be applied in production and achieved good results, such as bio-enzyme finishing technology, low-temperature plasma treatment technology\supercritical carbon dioxide dyeing. Technology, digital inkjet mesh, spray wax mesh and inkjet printing technology.

The application of high and new technology in textile production has promoted the modernization of traditional textile technology. The development of textile fiber raw materials and textile processing technology has improved the quality of textile products and expanded the variety of textile products. Textile products are entering various fields of the national economy and become an important raw material industry indispensable to the social economy and people's lives.

And promote the application of high-tech city in the textile industry. Promote the application of high-tech in the textile industry. From the actual situation, the international textile fiber new product development and the modernization of textile dyeing and finishing technology and equipment have changed the face of the traditional textile industry.

China's labor resources are abundant, wages are relatively low, and the textile industry's upgrading and transformation should be based on advanced and applicable technologies. It takes the road of high technology content, good economic returns, low resource consumption, less environmental pollution, and full advantage of human resources. The goal and focus of the new technology and advanced applicable technology transformation of the textile industry is to improve product quality, expand varieties, increase labor productivity, reduce product costs, and enhance the international competitiveness of products.

China has a vast territory, and the level of social and economic development varies from place to place. The requirements for the quality and variety of textile products are also different. The technological transformation of textile enterprises must be adapted to local conditions. According to market demand, starting from the actual situation of the region and the enterprise, we should consider the varieties, quality, grades, raw materials, labor costs, technical strength, management level, source of funds, and affordability of enterprises. The subjective and objective conditions of the factors determine the direction and positioning of the enterprise's products, and choose to determine the transformation plan.

Enterprises in the coastal areas and central cities that focus on export products should take advantage of technology, management, talents, information, etc., and adopt more advanced technologies and equipment to develop and produce high-grade, refined and deep-processed products to form the enterprise. The featured products and superior products achieve better economic benefits.

Enterprises in the central and western regions, small and medium-sized cities and towns and raw material producing areas should give full play to the advantages of abundant resources and labor, determine the direction and positioning of products according to the actual conditions of enterprise technology, management, talents and funds, and determine the goals and measures for technological progress. Enterprises that have the conditions to develop and produce refined and deep-processed products should also adopt advanced technology and equipment to produce products with better quality, higher grades and adapt to market demand, so that enterprises can enter a virtuous cycle and healthy development track.

2. Promoting the application of high and new technology in the textile industry is responsible for the rapid development of innovative science and technology. The role of interdisciplinary research in the advancement of traditional textile industry technology is manifested in the continuous improvement of fiber quality and the innovation of varieties, which are reflected in the textile dyeing and finishing process. Rapid development of technology and equipment. China's natural fiber should further improve the quality and improve the initial processing technology. Chemical fibers should strengthen the development and innovation of differentiated fibers, functional fibers, high-performance fibers and a new generation of environmentally friendly fibers. International textile technology has developed to a fully automated production stage. China's textile industry must first make a group of urgently needed advanced applicable technologies, such as automatic winding and shuttleless looms, to catch up with the international advanced level, comprehensively track the development of international textile technology, and develop and innovate. Develop a new generation of high-level technology and equipment with independent intellectual property rights in China. In the dyeing and finishing, we must focus on improving the automation of the whole process of dyeing and finishing, including automatic color measurement, color separation, color matching, automatic pulping and other auxiliary equipment to ensure the stability, consistency and reproducibility of product quality. It is necessary to pay attention to the study of the use of advanced technologies in other disciplines such as biotechnology, nanotechnology, genetic modification technology, etc. to improve the technical level of textile dyeing and finishing production.

The report of the 16th National Congress of the Communist Party of China highly praised the spirit of innovation and pointed out: "Innovation is the soul of a nation's progress and an inexhaustible motive force for a country's prosperity and development." The development of new textile products should be based on innovation and based on original new technologies. The competition in the international textile market is characterized by competition of quality and price. The essence is the competition of science and technology. It is the competition of transforming traditional industries with high and new technology, and the competition for technological innovation ability of textile production. It is necessary to strengthen the sense of innovation, attach importance to institutional innovation and mechanism innovation, and gradually make China's textile product development and development work into a virtuous cycle of development.

3. The key to promoting the application of high and new technology in the textile industry is that the key to talent development and innovation is talents. Under the guidance of the principle of rejuvenating the country through science and education, China's education reform is deepening. The scale of higher education and vocational education has been continuously expanded, and the level of disciplines has been continuously improved. A large number of professional talents are being cultivated. High-quality scientific and technological talents must have solid basic theoretical knowledge and rich practical experience. The textile industry based on applied technology should pay more attention to cultivating innovative leaders in the practice of scientific research and production technology. .

The textile industry is an eternal industry. China's textile industry is facing two major development opportunities: joining the WTO, China's textile industry has accelerated its integration into the international market, and it has ushered in a rare opportunity for development. The comprehensive construction of a well-off society proposed by the 16th National Congress of the Communist Party of China has also shown great development prospects for China's textile industry. For a long time, the textile industry will continue to be the pillar industry for China's export earnings, especially net foreign exchange earning. China's fee level is still very low. With the development of social economy and the improvement of people's living standards, there is still much room for development in the domestic market of China's textile products. Ample labor resources are a major advantage for China's development of the textile industry, and also an important area for resettling labor and employment. China's textile industry must seize the opportunity, accelerate structural adjustment, promote industrial upgrading, and strive to follow up on the development of international textile technology, and to achieve the goal of building a textile power.
