In recent years, the adoption of a large number of new technologies has improved the level of equipment in China's textile industry. In this regard, rapier looms and air-jet looms with higher levels of mechatronics have the most obvious effect. Electronic rapier looms and air jet looms, in the mechanical and electrical integration technology of various sports institutions, mainly include electronic let-off, electronic take-up, weft insertion systems, and electromechanical integration of weft selection systems. The electronic control system optimally controls the motion of each mechanism and improves the process adaptability. The equipment has the functions of automatically changing the fabric design, automatically detecting and analyzing the weaving reed, and automatically adjusting the weft density error, etc., and solves the electronic multi-arms, electronic jacquard devices and electronic storage of textile machinery. The high speed adaptability of key components such as wefts and electronic weft selectors improves the speed and efficiency of the loom. Industry experts on the current operation of the equipment after survey of textile companies believe that 70 to 80 years of production equipment used in China's textile enterprises accounted for about 30% of all devices, but the total power consumption of about 30% to 50%. Among them, AC motors account for about 75% . At present, the weighted average operating efficiency of various types of motors in our textile enterprises is 3 to 5 percentage points lower than in foreign countries. The efficiency of heating systems and pumps is 2 to 3 percentage points lower than in developed countries, and the overall operating efficiency of motor drive systems is lower than that of foreign countries. Nearly 20% . If the transformation is carried out according to 10% of the total capacity of the motor, and the average annual operation is 4000 hours, the energy saving rate can reach 20% to 25% . It can be seen that the energy saving of the motor system is currently the most commercial potential area for the textile machinery equipment market in China. For example, the polyester staple fiber complete sets of equipment with a daily output of 200 tons and over 200 tons developed by Zhengzhou Textile Machinery Co., Ltd. have adopted a large number of frequency conversion speed-regulation energy-saving technologies and information sensing technologies, which enables this type of large-capacity polyester staple fiber complete sets of equipment to realize a reduction in investment costs. And the purpose of operating costs, with better economic benefits. With the same capacity, a 200- ton/day production line can reduce 32% of investment, 53% of floor space, and 40% of labor costs compared to two 100- ton/day lines. In addition, the High Speed ​​Viscose Filament Continuous Spinning Machine developed by the Hongda Research Institute, due to the adoption of servo motors, PLCs , human-machine interfaces and other technologies, can spin forming, washing, drying and oiling, winding into a tube, etc. The processing steps are combined in one and the entire process time is greatly shortened; the spinning speed is increased to 140 meters per minute by means of forming in the tube. At present, high-speed viscose filament continuous spinning machines are required to solve the technical problems of quality indicators for continuous spinning stock solution, high-speed spinning process parameters, selection of post-processing roll materials, and processing, winding mechanism, and bobbin forming. The adoption of new and high technologies has provided material guarantees for improving yarn quality and productivity, reducing labor and increasing labor productivity.
The textile industry in China's energy consumption industry, although the energy consumption is less than the power, energy, paper and other industries, but in the total motor capacity used, less than 20% of the motor is with frequency control. China's textile machinery industry has a frequency-controlled motor market share of less than 15% , while China's inverter market has maintained a high growth rate of 26.8% in the past 10 years. In the next 10 years, the demand for inverters in China's textile equipment will remain strong. With the application of control technology and energy-saving technologies tending to mature, the market potential of inverters in the textile machinery industry will reach 5 billion to 10 billion yuan.
