Imports Of Textile Equipment In Quanzhou Showed An Increasing Trend.

Less than p ago, the Fujian Quanzhou inspection and Quarantine Bureau announced that in the month of 1~10, the Quanzhou inspection and Quarantine Bureau inspected and supervised the import of all kinds of imported "a" target= "_blank" href= "http://www.91se91.com/" > textile < /a > equipment 68 batches and 63 million 930 thousand US dollars, representing an increase of 142.8% and 68.2% respectively over the same period.

Data show that the import of advanced textile equipment has increased significantly.

A total of 1356 sets of textile equipment are mostly internationally advanced equipment, including air-jet looms, warp knitting machines, dyeing machines, etc. < a href= "http://sjfzxm.com/news/index_s.asp" > textile industry < /a > complete sets of equipment and textile machinery parts and components, mainly from Germany, Switzerland, Italy, Japan, China Taiwan and other countries and regions.

According to the insiders, this shows that Quanzhou textile "a target=" _blank "href=" http://www.91se91.com/ "clothing" /a "industry increases the import of advanced textile equipment, and promotes the accelerated pformation and upgrading of industries to become a new trend.

< /p >

Since the beginning of this year, many textile and garment enterprises have seized the opportunity of a series of pformation and upgrading of the country, and actively introduced advanced textile machinery with high technology, high reliability, energy efficiency and high efficiency, gradually adjusting product mix, enriching product levels, increasing product stalls and added value, and effectively coping with many unfavorable factors such as the global economic downturn, RMB appreciation, labor shortage, rising costs, and high barriers to international trade.

< p > at present, the automation and intellectualized textile machinery equipment has more and more obvious effects on relieving the cost pressure of human resources and improving the quality of products.

But the experts in the industry generally believe that textile equipment should pay more attention to energy saving while pursuing automation, high speed and high output.

< /p >

< p > < strong > focus on energy saving at the right time < /strong > /p >

< p > in the recently held "a href=" http://sjfzxm.com/news/index_s.asp "Twelfth Asian Textile Conference" and the 2013 China Textile academic annual conference, Professor Thomas Gries of the Textile Technology Research Institute of Rheinisch Westfaelische Technische Hochschule Aachen University (RWTHAachen) made a keynote speech entitled "energy efficiency in textile production -- best practices and beyond the advanced level".

In his report, he suggested that producers should pay attention to energy efficiency in the design and use of textile equipment.

< /p >

< p > Thomas Gries thinks that for the textile industry, energy is the decisive factor of cost, so energy efficiency is one of the most important problems in the sales of textile equipment.

He introduced the development trend of energy efficiency in the textile industry, including high energy drive system, energy recovery and advanced process control technology, and interpreted some advanced textile equipment applications of these technologies.

He believes that improving energy efficiency is not only a consideration of cost saving, but also an important issue related to future development.

< /p >

< p > < a href= "http://sjfzxm.com/news/index_c.asp > > Hong Haicang, senior engineer of Shanghai Textile Engineering Society < /a >, at present, some foreign businessmen in Jiangsu have asked export enterprises to indicate the phenomenon of energy consumption per unit output.

When this demand is increasing, the domestic textile enterprises try to keep up with this requirement.

< /p >

< p > when it comes to the energy saving problem of looms, Hong Haicang thinks that the biggest problem of air-jet looms is how to reduce energy consumption.

For the production of similar products, rapier looms can save energy by 30% compared with air-jet looms.

About 70% of the energy consumption of air-jet looms is used for gas supply systems.

Under the current operation mode of the gas supply system, it is very difficult to reduce the energy consumption of air-jet looms.

< /p >

< p > < strong > automation reduces energy consumption per unit area less than /strong > /p >

< p > automation equipment needs additional control system and more motors and frequency converters. These will increase energy consumption. The pmission system of coarse and thin links can be driven by power and increase energy consumption. The increase of equipment output requires higher power and higher energy consumption.

But Zhu Xianmin, vice director of the China Textile machinery and Equipment Association, thinks that the degree of automation of the equipment is high, and it will increase the energy consumption from the surface. However, the average energy consumption per unit area has not increased.

< /p >

< p > the Key Laboratory of textile fiber and products of Ministry of education of Wuhan Textile University has carried out an investigation on the energy consumption of traditional textile equipment and new automatic textile equipment, proving the superiority of automatic textile equipment in saving energy.

< /p >

< p > the researchers conducted a comparative experiment in Hubei Li Mei Textile Co., Ltd.

Li Mei textile has two production lines of 30 thousand spindles, one is the K45 compact spinning production line, the other is the traditional combed cotton production line, producing 100 cotton and 45 British cotton yarn respectively.

The researchers converted the energy consumption of two kinds of pure cotton yarn into 21 pure cotton yarn per kilogram yarn energy consumption.

The energy consumption per kilogram yarn of the K45 compact spinning line is 0.8499 kilowatts, and the energy consumption per kilogram yarn of the traditional combed cotton spinning is 1.112 kilowatts.

Therefore, researchers believe that the use of new automated textile equipment will increase energy consumption, but it will also increase production and improve yarn quality.

Compared to the standard yarns, the new automated textile equipment still has advantages in energy saving.

< /p >

< p > in addition to comparing the energy consumption of the whole production line, the researchers also compared the energy consumption of single equipment and continuous production system.

Researcher Zhang Huijuan said that the modern blowing carding system has smaller floor area, lower air consumption and lower energy consumption compared with the traditional carding production line.

In the energy consumption comparison test of three different types of carding machines, the energy consumption per kilogram cotton sliver produced by modern high production carding machine is 82.6 kilowatt hours, while the traditional carding machine is 102 kilowatt hour and 98.6 kilowatt hour respectively.

Because the speed is improved, modern technology is more energy efficient.

< /p >

< p > < strong > intelligence is the way to save energy < /strong > < /p >

< p > for the future development direction of textile equipment, Zhu Xianmin thinks that it is the way to continue to develop intellectualized.

He believes that energy conservation is also a goal of intelligent equipment.

For example, although some devices are not working at present, they still need to keep running, which is to prevent the equipment from running normally after starting up, and in this process there is energy consumption.

If the equipment achieves a higher level of intelligence, it can stop completely without needing to run, and it can achieve the energy saving effect when the heating is preheated ahead of time.

< p > air jet looms, as the most energy consuming households, mainly use the method of dynamic and precise control of weft insertion process to control the opening and closing time of the main and auxiliary nozzles solenoid valves and the time of the air injection, so as to achieve the purpose of energy saving.

At present, the energy saving technology of weft insertion dynamic control includes: implementing closed loop control for weft insertion process and improving the accuracy of weft insertion; adopting low pressure weft insertion technology to make weft yarn low tension weft insertion to reduce air consumption; improving the structure of the nozzle, increasing the concentration of the airflow and reducing the consumption of gas; supplying air to the main and auxiliary nozzles by using multiple air bags; using auxiliary air bags with different compressed air for different weft weaving, so that the main nozzle pressure of each weft insertion can be adjusted, and the auxiliary nozzles can carry out two automatic switching of air pressure; the Gao Min small chamber electromagnetic valve is selected, the gas path is shortened, the gas path is optimized, and the number of nozzles is controlled by optimizing the electromagnetic valve, so as to achieve the purpose of energy saving.

< /p >

< p > Hong Haicang introduced the "A9500" a href= "http://sjfzxm.com/news/index_s.asp" > air-jet loom < /a > in the year of Suhl, Switzerland, which can detect the flying speed of weft at the entrance of weft yarn, and adjust the opening and closing time of the auxiliary nozzle when the weft is in place, which can save about 25% of the air consumption.

At present, Nissan and homemade looms are still difficult to achieve this. Most of them are adjusted in second weft.

This technology requires rapid detection of looms, rapid response of control system and rapid processing of equipment.

To achieve higher automation and Intelligentization in these three aspects, the energy consumption of air-jet looms can be further reduced.

< /p >

< p > in the intelligent energy saving control system of twister based on S3C2416 in Shaoxing Sheng Pu Electronic Technology Co., Ltd., the induction motor used in the "a href=" http://sjfzxm.com/news/index_s.asp "traditional double twister" less than /a is replaced by permanent magnet AC synchronous servo motor, achieving a certain energy saving effect.

Through the control of the controller, the influence of the motor startup and braking on the power grid is reduced, and the driver can also make the motor load constant and reduce the energy consumption.
