    < p > by the end of 2011, "one step process of different shrinkage and mixed yarn industrialization technology and application project" won the first prize of China's < a href= "http://www.91se91.com/" target= "_blank" > textile < /a > Industrial Association's science and technology progress. The technology is a major technological breakthrough in the world's chemical fiber industry, marking the arrival of a new era of chemical fiber spinning. With the advent of this technological invention, the Polytron Technologies Inc, the Xuzhou main product of the project, has attracted extensive attention from the industry. < /p >
    P, founded in 2003, is the first Jiangsu high-tech enterprise to respond to the Jiangsu provincial Party committee's provincial government's "South of Jiangsu industry transferring to North Jiangsu". After nearly 10 years of development, at present, the group has 9 companies, including Limited by Share Ltd, Jiangsu Limited by Share Ltd, subsidiary company Xuzhou SHK Ke fiber Polytron Technologies Inc, Xuzhou Rongsheng fiber products Technology Co., Ltd., and has the annual production capacity of 56000 tons, different shrinkage differential blending wires, all kinds of textile < a href= "http://www.91se91.com/" target= "_blank" > clothing < /a > fabric 140 million meters. < /p >
    < p > < strong > overcome the difficulty of one step spinning technology < /strong > < /p >
    Sun Derong, chairman of Xuzhou P Polytron Technologies Inc, said: "we eat by innovation. Only product innovation can lead the market. It is precisely this sentence that made Silk embark on an innovative way to independently develop and subvert traditional crafts from the day he entered the textile industry. < /p >
    < p > the traditional two step process of chemical fiber spinning is to spin POY and FDY separately, then compound POY and FDY. Sun Derong said that due to the limitations of the technology, the quality of the yarn produced by the two step method is not high, and the varieties are single, which can only be roving, and can not meet the requirements of spinning. Therefore, in order to change this situation, we must innovate the processing technology. < /p >
    < p > how to carry out technological innovation? He has no successful experience to draw lessons from. The one-step technology is still blank in China, and many technical problems have not yet been broken down internationally. However, in the past few years, he has not withdrawn, and persisted in the idea of strengthening science and technology. In the past few years, he hired Jiang Shicheng, a member of the Chinese Academy of engineering, and joined the Donghua University, China a href= "http://www.91se91.com/news/" > Textile Science Research Institute < /a >, Beijing Zhongli machine company to form a scientific research team, and created a one-step 16 head / bit spinning winding technology. On the basis of this, a one-step 24 head / bit spinning winding process was developed, and industrialization was realized. Sun Derong is proud to say that one-step mixed fiber 24 head / bit spinning and winding is the first in the world, that is to say, they have conquered the unsolved technical problems of Germany's Bama and hahester. < /p >
    < p > "one of the most direct benefits that a one-step approach brings to an enterprise is increasing production and reducing costs." Sun Derong gave the reporters an account: compared with the two step method, the one-step method saves 46% of the land occupation, reduces the plant area by 57%, saves 830KWh per ton of products, saves electricity by 41%, and the material consumption per ton of products is reduced by 15Kg. The cost per ton of products is reduced by 1000 yuan compared with the two step method, which greatly reduces the energy consumption of the production. In addition, the one-step POY/FDY heterogeneous shrinkage hybrid filament production technology has achieved breakthroughs in key technologies such as tension matching of POY and FDY composite points, precise control of fiber aggregation structure, and high-speed network compounding, and so on. It has overcome the technical bottlenecks of POY and FDY homogeneous composite, stable shrinkage, high fiber holding capacity and other technical bottlenecks. It can produce high value-added products such as irregular shaped, cross section, fine denier, super fine denier, PET fiber and colorful composite wire. < /p >
    < p > < strong > sacrificing the interests of the company to promote the progress of the industry < /strong > /p >
    < p > "without strong technical support, we can hardly imagine the success of one-step technology." When it comes to successful experience, Sun Derong emphasized that at the beginning of the founding of the group, we attached great importance to the construction of scientific and technological innovation platform and talent team. In cooperation with universities and research institutes, they have created the only workstation of the Chinese textile industry academician workstation, established the Jiangsu multi heterogeneous mixed filament manufacturing engineering technology research center, Jiangsu functional memory fabric Engineering Technology Research Center, and Jiangsu province recognized enterprise technology center, and jointly established the technological research and development platform of Donghua University Modern Textile Research Institute, Jiangsu joint research and development center. In 2011, after the assessment and approval of the China Textile Industry Federation, China Chemical Fiber Association and textile product development center, the company set up the "national difference shrinkage multi component < a href=" http://www.91se91.com/news/index_c.asp "mixed fiber product" /a development base. < /p >
    < p > all these provide strong guarantee for their R & D. Of course, it is also inseparable from strong financial support. From 2008 to 2012, she invested 67 million 650 thousand yuan in R & D funds. < /p >
    < p > {page_break} < /p >
    < p > < /p >.
    < p > innovation of production technology also means the change of processing equipment. The traditional two step method requires three sets of equipment. First, two sets of equipment are used to spin out POY and FDY, and then to third sets of equipment to compound. The use of one step can meet spinning requirements with only one set of equipment, which is also called integrated equipment or three machine in one device. Sun Derong said, at that time, they took the drawings of their own design equipment to Zhongli to process. Zhongli replied: "it can be processed, but it is irresponsible to spin silk." However, it was unexpected to Zhongli that the equipment was not only spun silk after it was put into production, but also won a large number of orders for Zhongli in the future. "We signed a three year protection period with Zhongli, but less than a year later, Zhongli asked for a cancellation. The reason was that too many companies lined up to buy equipment. We have to give up the protection period of three years, which is also a contribution we have made for the industry. " When it comes to this topic, Sun Derong has no regrets. He said that monopolizing a technology success is not a permanent solution. The company is still adhering to the innovative attitude and constantly developing and producing new products on the basis of one-step process. < /p >
    < p > < strong > differentiation enables enterprises to take the lead step by step < /strong > /p >
    < p > "one-step method is not only changing the spinning process, but also using this silk fabric is unique." Sun Derong said that the shalke group adopted the new colorful silk fabric developed by our company's colorful silk raw materials. In the 2012 China Spring and summer fashion fabric evaluation, there were altogether 9 new a href= "http://www.91se91.com" > fabric < /a > finalists. One of them was "Prizes II", which was awarded the highest prize of "best scientific and Technological Innovation Award". < /p >
    < p > this silk is highly adaptable, knitted and woven. Sun Derong mentioned in particular that these two years' curtains were very popular in the home textile market. This kind of shading cloth is essentially different from the previous shading cloth. Before it was made of cloth, coating on the cloth surface could achieve the effect of shading. However, with the increase of washing times, the shading effect will gradually weaken. And the shade cloth produced by Silk is to achieve the effect of shading by changing the fiber structure and increasing the bulking degree. Its shading function will never deteriorate. At the same time, because it eliminates the finishing of the coating and makes the fabric more environmentally friendly, it is well received by consumers. < /p >
    The charm of < p > a href= "http://www.91se91.com" > chemical fiber < /a > lies in the variability of its structure. The spun silk takes account of some functions from the beginning of slicing, so it can better reflect the functionalization of products. Moreover, the downstream weaving enterprises are difficult to imitate because they can not get the matching ratio of raw materials, which further protects the interests of developers of new products. At the 2013 China International fabric exhibition held in Beijing recently, silk exhibited the second generation of silk fabrics produced by one step spinning, attracting many visitors' eyeballs. Sun Derong said that this fabric is their latest research and development, and there are no more than second in the market at present. He said that their current product development strategy is to take the road of differentiation and always take the lead. < /p >
