Spinning Technology Compact Spinning Ring Spinning Yarn Industry

Anhui Huamao Group Co., Ltd. has long been based on the manufacture of high quality, high quality, high technology content and high added value products. The advantages of compact spinning line are the ideal yarn of high grade < a target= "_blank" href= "http://www.91se91.com/" > textile "/a", and also become a sharp weapon for Huamao Group to build up its fist product.

Because of the elimination of twisting triangle area, the hairiness of compact spinning is very small, especially the hairiness above 3 millimeters. In spinning, as the single fibers are twisted under the condition of stretching and parallel, the force of the single fibers is basically the same when the single yarn is pulled, so the compact spinning strength is higher than that of the traditional single yarn. And because the single fiber in compact spinning is tightly arranged, and the force between them is large, it also helps to improve yarn strength and yarn strength by 5~10%. 
 compact spinning has less hairiness, reduces the pressure of sizing, singeing and other processes, is conducive to the production of the next process, improves the speed and efficiency of looms, improves the knitted fabric properties, and greatly improves the anti fuzzing and pilling properties. Not only that, compact spinning has wide range of gauze, which can be used from 20S to 330S. Raw materials can be used from cotton, linen, wool, silk natural fibers to various chemical fibers, differential fibers, etc., which can meet different needs of different levels of the market. 
 because the appearance quality of compact textile products is fine and the arrangement between fiber roots and roots is fine and compact, the fabric has good gloss and feel, which is very beneficial to the downstream processing, especially the advantages of less hairiness and high strength of single yarn. It makes the production efficiency high and the fabric quality greatly improved. It can be processed into many high-end exquisite a target= "_blank" href= "http://www.91se91.com/" > clothing "/a" fabric, and the scale of production is bigger and bigger in our country. Especially since 2008, compact spinning has started large-scale operation in China. According to statistics, in 2008, China's compact spinning production scale was about 5 million spindles, and by the end of 2012, it expanded rapidly to about 13 million spindles. Among them, Shandong and Jiangsu achieved nearly 5 million spindles, and only three of Anhui's Huamao, Wuxi cotton and Shandong Lu Tai had about 1000000 spindles. The industry expects that the compact spinning production scale has exceeded 20 million spindles in 2013. 
Xie Chunping, Professor of textile < a href= "http://www.91se91.com/news/" > School of clothing, < /a >, pointed out that at present, the penetration rate of compact spinning in the international market is more than 30%, while that in China is only about 8%. The compact spinning technology still has great room for development in our country, P. 
 high quality brings high efficiency 
 in recent years, people's demand for high quality textiles is more and more obvious, and low-end products are hard to meet the needs of the market. In large enterprises such as Anhui Huamao and Wuxi cotton, compact spinning technology is mostly produced in high-end yarns. The raw materials of compact spinning can be widely adapted, and can be used to spin various kinds of differential fibers, which also meet the diversified needs of people. 
 the efficiency of compact spinning is to see the degree of automation of enterprise equipment and the management of enterprises on the other hand. If the product is of good quality and broken ends, not only the quality of the products is high, but also the employment will be greatly reduced. Professor Xie Chunping said that the production efficiency of compact spinning technology is quite different, especially the gap between labor and employment is obvious. At present, the number of ten thousand spindles used in China is different from that of 20~100 people. The higher the quality of products, the less labor force and the higher productivity. She introduced that in a domestic enterprise, the production equipment is highly automated and the product quality is strict. The 40 cars need only one truck driver to take care of it. 
 Anhui Huamao Group has always believed that good equipment and technology must be equipped with advanced production management so as to give full play to the advantages of the production technology. In daily maintenance, Huamao Group tamped the equipment basic management, and asked the mechanic to eliminate the skew spindle and the skew gas circle. The operation class was meticulous, standardized operation management, and the hotbed for producing yarn defects was eliminated; the technical departments were strict in quality management, so that the yarn produced was of good consistency and stable quality. There are strict requirements for Huamao in the workshop environment. The suitable temperature and humidity should be kept in the workshop, and the travelling air suction and suction device will be installed to prevent dust, flying flowers and short fibers from pumping into the compact spinning area, resulting in paste nets, ensuring the cleanliness of the draft area and the gathering area. 
 Hua Mao Group's < a href= "http://www.91se91.com" > compact spinning process < /a > "wind wind" brand yarn has uniform evenness, less yarn faults, single yarn strength irregularity, NEP impurity and hairiness, combed cotton yarn dyeing performance is good, main quality indicators are between ust 5%~25%, physical and appearance defects reach the first level of GB/T398-1993 standard and GB/T5324-1997 standard, which has long been praised by the market, and has won considerable economic benefits for the company. 
 improvement of technology, renewal of new vitality 
 compact spinning process is improved on the basis of ring spinning. Although the products are very popular, there is still much room for improvement in technology. Xie Chunping made some improvements on the basis of compact spinning, developed the technology of "full spun spinning", reduced the level of production energy consumption, solved the demanding problems of the compact spinning equipment to the workshop environment, and also improved the fabric surface effect, < a href= "http://www.91se91.com" > fabric < /a > handle. 
 full spinning is the use of narrow slot rollers as the original assembly. The roller type compact spinning mechanism is simple, and only one output rubber roller is installed on the roller for twisting or twisting tongs, so the spanmission is simple, and the cleaning and maintenance are convenient. Xie Chunping pointed out that the length of the spun aggregate area is longer, so that the negative pressure of the air flow can be reduced to below 1500Pa. Compared with the negative pressure of compact spinning 2000~2500Pa, the energy consumption of the equipment decreases very obviously. 
 compared with grid ring compact spinning, full spun spinning reduces Mao Yu's damage by more than 3 millimeters while making 1 millimeter beneficial for Mao Yu to retain. 1 mm hairiness can lubricate rings and travellers, prolong the service life, and also cover up the defects and uneven evenness of the yarn itself, so that the appearance of the cloth is better and closer to the style of the burnt yarn. The yarn evenness decreases obviously, and the spindle difference is smaller than that of other forms. When the humidity is high, there will be no fish seed yarn, Takesetsu Sa and so on. 
 the diameter of the front roller of the fully spun spinning is 50 millimeters, which can reduce the speed of the front roller by half, effectively extend the life of bearings and gears, and reduce mechanical failure. Canceling mesh ring, bridge gear and other wearing parts can save labor and save parts cost and make production more stable. In addition, it can be used for the modification of the long spinning machine with automatic doffing. It is also necessary to replace the suction plug and facilitate the low cost of spinning long and heavy trucks. 
 Xie Chunping pointed out that compact spinning technology is a systematic project. The device is not omnipotent. The key lies in the unified coordination of people, environment, raw materials and equipment. According to the technical requirements of compact spinning, the characteristics of compact spinning technology are comprehensively and systematically understood. It is necessary to pay attention to the precondition of the workshop environment first. Negative pressure has a great influence on the air flow and heat of the workshop. If these problems are not handled well, there will be a grid ring blockage and the deterioration of the yarn quality. In addition, combining closely with the actual production of cotton spinning enterprises, using high efficiency motor, improving fan impeller, reducing the resistance of negative pressure system, optimizing the design of the shape of suction port of special shaped tube, and improving the compact spinning negative pressure system, the energy consumption can be reduced by about 10% less than /p.
