? ????China Spinning Machine intense market competition, in the high-end products - compact spinning technology, market, Germany, Switzerland, Italy, Japan and other countries of the spinning machine manufacturers are also competing in the race, but has yet to become a monopoly of the Board. In this sense, the Chinese market, fierce competition compact spinning machine can be said that fierce competition in the world textile machinery market, the geographical extension of the situation. ????A direct impact on the quality of printing and dyeing yarn, knitting, yarn-dyed, garment and other industries, thus improving spinning technological progress and industrial upgrading for the development of the textile industry-wide significance. Conventional ring-type spinning machine as the industry advances, can not fully meet the needs of downstream processing quality, therefore, a higher-tech compact spinning technology, emerged in 1999 in Paris ITMA show, Rieter (Rieter), the German Green Ze (Zinser), Suessen (Sussen), etc. on display for the first time with the compact spinning technology, spinning frame, marking the great market potential of this innovative technology start of commercial operations. ????In Beijing CITME 2002 show, Rieter, Zinser, Xu Sen, Italy Marzoli (Marzoli), Toyota (Toyota), etc. were exhibited in China, based on their compact spinning technology, spinning frame, has become an overseas textile machinery and power began to a positive start to enter the huge China market, spinning inklings of new technology trends, the competitive situation in the burgeoning Chinese market. ????Suessen started from 1920, was founded in spinning technology research, by 2001 years later, has been sold in China alone, more than 200,000 children EliTe close spindle, China has become its largest market. ????Rieter is the world's first R & D Compact Yarn Spinning Technology, one of the vendors, but also the international launch of compact spinning spindles, one of the largest two companies. It Suessen cooperation in the field in the compact spinning continuously push forward the progress of the compact spinning technology, expand the scope of application of compact spinning technology, has become the leading compact spinning superposition in the traditional Ring Spinning an emerging technology Another pioneer in technology trends. ???Application of Principles and advantages of compact spinning ????The so-called compact spinning technology was developed in the ring fine spinning machine, a new device, in essence Textile Drafting System before the addition of a fiber pool area, eliminating the front roller to the twisted spinning triangle between points, thus eliminating the triangular area right into the yarn surface structure (especially the hairiness), yarn strength and flexibility, spinning run performance (breakage) and free flyings (environmental cleanliness), etc. effects. ????Specifically, before the roller is a spinning machine in front of the traditional design called for a special-shaped straw, grid porous apron and output negative pressure on the roller composed of condensed areas, effective control of fiber, especially fiber edge fibers and planktonic production, thus eliminating the spinning triangle, so that the fluff of cotton yarn has decreased significantly, nep reduced by 30%, 70% reduction in hairiness than the ring and improve the yarn strength of about 10%, and cotton seed, processing flyings less for the after-processing operations to improve fabric quality and reduce the burden sizing, singeing and so created the conditions for cancellation. The current global installed base has more than one million, and technological advantages may be reflected in glimpse. ????In the same tight ring under the conditions of raw cotton yarn than conventional ring yarn quality, high output, low twist, use a wide range of raw materials, producing the same pure cotton yarn with cotton may be appropriate to reduce the levels and production costs. For example, production of 30 English teams off the cotton combed yarn can be reduced up to 20%, while the yarn quality and appearance are still intact. ???Technology Comparison ????Internationally renowned manufacturers to launch compact spinning of different forms, of which Li Da, Xu Sen, Marzoli, Toyota and Zinser most representative. ????Lida pioneered an alternative to suction drum spinning under the roller drafting device before the condensation of the system, the company developed compact spinning brand - ComforSpin spinning (Com4, ComforSpin) the successful occupation of compact spinning equipment market, able to spin out in the off Strong, strong extension, such as yarn hairiness, and IPI indicators of the quality better performance than conventional ring yarn in close fine yarn. ????Com4 compact spinning roller installed in the concentration of a helical cylindrical rolling, mainly spinning yarn count for more than 60 English teams when the selection; spinning less than 60 English teams, still using flat roller. ????To July 30, 2003, The People's Republic of China State Intellectual Property Office issued the patent announcement, Rieter in the 203 patent applications, 26 projects involving ring-spun yarn spinning technology closely. ????Suessen EliTe compact spinning increased the ring spinning machine-assisted anterior seam roller, and has opened a trough shaped hollow suction tube, above the rotary movement can be covered with the skin with a pore volumes, when the fiber bundle provided through Suessen drafting system immediately after the arrival EliTe cluster part of the grooved seam negative pressure air through the straw covering the shaped straw hole of the aprons, air to leave the front roller by the cluster of fiber JAW controlled so that the "spinning triangle" reduced or eliminated, so that fibers parallel to each other and finally spun yarn tightly. ????In ShanghaiTex 2003 show, demonstrated the use of compact spinning technology to produce compact spinning strands EliTwist. The use of stock-line technology, also developed a close Siro core-spinning equipment, namely, compact spinning, siro spinning, core-spun yarn triple. According to reports, this is the international advanced level of the host equipment, spinning, spinning yarn quality is superior to various other forms. ????Toyota ShanghaiTex 2003 exhibition RX240NEW-EST compact spinning spinning frame, which uses air flow cluster type, the front of the lower one for each 4 by the suction tank, and lead aprons under the porous roller composed of a combination of pieces of The combination of pieces can be easily removable without tools; with a roller gear under the former system of fuel through the gears without the need to drive, porous aprons from under the front roller drive; suction pipe installed in the Luo Laji Block upper part of the suction fan variable frequency drives, each section 48. ????The scene in the textile JC40, spindle speed of 23,000 rev / min spindle using 18mm plate, 36mm steel collar, forming part of the use of servo motor. ????Marzoli display Olfil compact spinning device installed in the RST-1-type spinning frame on the car spinning demonstration. The device is installed in the three systems on the drawing three times before the department, the bottom one for each of eight stainless steel tubes, (each spindle sets of holes along the aprons), in stainless steel pipe has opened a suction slot; upper between the two leather roller by the toothed belt drive; suction fan variable frequency drives, each 48 1. ????Zinser 700 AirComTex close compact spinning machine spinning device unique, its concentration in the suction part of the upper section to be spinning, spinning to three roller drafting, as amended, by the negative pressure airflow guide, be concentrated to the Aprons surface of the upper punch. Aprons of the pitch due to a smaller hole, so that should be the width of pre-twisting has been significantly reduced. ????In addition, gathering area and the concentration of drafting roller with changing gears between the rollers, can choose among the different transmission gears, processing a wide variety of fibers. ????The company emphasized retention 2mm below the hairiness, the coverage of the textile end product capabilities and other performance is very important. ?????In addition, Ruishiluotuo Kraft (Rotorcraft) has introduced a cluster of compact spinning mechanical prototype RoCoS, it is still using three roller drafting, the former roller must be 27mm diameter, the original pre-roller and close on the anterior roller with a plastic frame fixed together, the two former in between the upper roller, a ceramic collector, ceramic collector openings for third gear change according to Variety. ?????Characterized by the transformation of convenience, domestic YJ2-142 series cradle spinning frame can be modified, as long as for a front roller and the roller seat, coupled with compact spinning device can be. Another advantage is that energy conservation, it does not require external blower vacuum, and therefore energy consumption and the general ring, the company has and Shanxi Best companies to launch domestic spinning of the rehabilitation programs. ????Domestic Trends ????In the international application of compact spinning technology into the mature period of time, some domestic textile machinery manufacturers and research institutions are also optimistic about the application of strong prospects for yarn spinning technology, invested R & D and learning, including large, medium, small and private textile machinery manufacturers, research institutions, universities and even some spinning science and technology personnel, are committed to this professional field, in order to develop a compact spinning with independent intellectual property rights program to work techniques, including Shanghai Jingwei Textile Machinery, and two textile machinery has been made in the initial research achievements, and through ShanghaiTex 2003 Exhibition, to the Chinese market has matured a collective spooling device. ????Meanwhile, domestic manufacturers and international manufacturers to develop the case is also endless.
