Textile industry: energy-saving, high-efficiency, reducing labor is the development trend

Editor's note: Not long ago, many new products emerged at the ITMA2011 International Textile Machinery Exhibition held in Barcelona, u200bu200bSpain. These products embodied the characteristics of high speed, high efficiency, energy saving, and labor reduction. Wu Yanwen, a senior engineer of the Secretariat of the China-Mauritian Association, and Zhao Yuan and Shen Chunhui of Shanghai Pacific Electromechanical Group, etc., after visiting the exhibition site to learn about the performance of the exhibits, specially wrote this article, and made a judgment on the current situation and future development trends of textile machinery. prediction. The products exhibited at the ITMA 2011 International Textile Machinery Exhibition in Barcelona, u200bu200bSpain this year cover all levels of textile machinery, equipment, equipment and other supporting service industries, focusing more on scientific and technological innovation and the promotion of new technologies, representing the highest level of the international textile machinery manufacturing industry. Direction of development. The level of intelligence has been greatly improved. There are 7 exhibition halls in the ITMA2011 International Textile Machinery Exhibition in Barcelona, u200bu200bSpain. 4 of them are dyeing and finishing equipment, occupying half of the entire exhibition. 2 exhibition halls exhibit spinning machinery. There is 1 exhibition hall exhibiting weaving equipment, including knitting and woven machinery. There are many non-woven fabrics and quilting equipment throughout the exhibition, and the physical exhibition occupies a lot of space, becoming a highlight of the exhibition.　　 High-speed, high-efficiency, energy-saving, and labor-reduction are the outstanding features of all exhibiting equipment. It can be seen that the machine parts manufacturing technology, electronic numerical control technology and production process automation and intelligent online control technology of the physical products at each booth have been greatly improved. For example, the new generation of rotor spinning equipment launched by Oerlikon in Switzerland has a speed of 200,000 revolutions per minute; the maximum speed of the air-jet loom exhibited by Picanol in Belgium can reach 2013 revolutions per minute; intelligent matching with high speed The electrical setting makes the operation easier and safer, and the machine parts of the equipment are more precise and rigorous from casting processing to polishing and installation. We not only saw the high-speed operation of the machinery at the exhibition, but also visited Picanol on the spot and left a deep impression. The rotor spinning, compact spinning, and fancy yarn spinning machines that reflect the energy-saving and high-efficiency common spinning equipment are the most exhibited. Among them, the rotor spinning of Oerlikon of Switzerland has made greater technological breakthroughs, and the combination of thick and thin windings of Spain's Marzori and Japan's Murata The physical display of the production line occupies a lot of space. The uniqueness of these products is that it maximizes the saving of production land, saves labor costs, improves on-line monitoring and facilitates production management. The flat carding machine launched by the German Trützschler company shows its exquisite mechanical manufacturing technology and its beautiful appearance in perspective: it raises the cylinder, makes the carding sticks more compact, and the card clothing adopts magnetism. The inlaid type is convenient for installation and replacement, and avoids the damage to the edge of the card clothing caused by the card sleeve type installation. The autoleveler on the head draw frame with patented technology introduced by the company at the same time realizes the whole process of leveling the yarn. The French NSC company only exhibited one wool spinning combing machine, and its main energy was on the display of non-woven machinery. For the woven part, the rapier loom of Picanol from Belgium and the JAT710 series of air jet loom from Toyota of Japan are the most conspicuous. The warp-knitting circular knitting machine exhibited in the knitting exhibition area particularly attracted the attention of the audience; the computer flat knitting machine exhibitors mainly include Cixing Co., Ltd., Shaoxing Jinhao Machinery Manufacturing Co., Ltd., Shima Seiki of Japan, and STOLL of Germany. Among them, the German STOLL booth was much larger than the exhibition scale at the 15th Shanghai International Textile Industry Exhibition held in China in June this year. The company not only displayed the oldest small knitting machine in the growth history of STOLL. , Hand-cranked flat knitting machines, engraved jacquard knitting machines, to review the development history of flat knitting machines to prove its dominance, and also exhibited 11 latest computerized flat knitting machines with different functions. Special booths for industrial supplies have also been set up. These products are mainly used for medical protective gear, body armor reinforcement, industrial filters, etc.
