The forum attracted more than 600 outstanding technicians from the national textile industry, and the delegates who participated in the two-day forum expressed their great benefits.
Break through the bottleneck and win by innovation.
Yang Jichao, vice president of China National Textile and Apparel Council, pointed out at the meeting: "At present, the industrial development situation in China is not optimistic. The development of textile industry is squeezed by the control of high-end products in developed countries and the low-price competition of low-end products in developing countries, which highlights the importance of structural adjustment and industrial upgrading. Guiding enterprises to increase R&D, improve their independent innovation ability and integrate industrial resources has become the key to the prosperity of textile industry. Through years of efforts, enterprises have made great achievements in independent innovation and structural adjustment, and new technologies, new processes and new products are constantly emerging. At present, it is a critical period for the industry to change from scale economy to value economy. It is of great significance to grasp the direction of industry policy, understand the development trend of products, grasp the dynamics of market demand, and exchange and learn advanced production experience. "
After years of rapid development, the scale and production capacity of China's textile industry has been in the forefront of the world. At the same time, it is bound to encounter challenges. How to break through the current predicament and achieve the goal of sustainable development is a big problem that the whole industry is thinking about. Fu Enfu, director of the National Cotton Textile Science and Technology Information Center, said in his speech at the meeting: "We need to break the inherent thinking mode, seek technological breakthroughs, further improve the technical content and added value of textile products, and start from the upstream of fiber, yarn, fabric and other industrial chains to deeply tap the potential of products and enhance market competitiveness." Director Fu said that the current competition in the textile industry, on the surface, is market competition, but in fact it is a comprehensive competition of technological innovation, product innovation and management innovation. He quoted Wang Tiankai, president of China National Textile and Apparel Council, who put forward four viewpoints on innovation at the 20 12 annual meeting of textile innovation: innovation must first firmly establish a correct management and development concept; Innovation needs overall design and system operation; Innovation needs to be scientific and pragmatic; Innovation needs persistence. For these four points, Director Fu believes that it is not a one-off event to do a good job of activation, but as long as we follow this idea, change our concepts, adhere to the route of structural adjustment and industrial upgrading, and realize the goal of becoming a textile power just around the corner.
Yao Mu, an academician of China Academy of Engineering, gave a keynote speech to the president. In his speech, he pointed out that the technological innovation of the spinning industry has made great progress in recent years: "On the basis of compact spinning, siro spinning and cable spinning, ring spinning will continue to develop embedded composite spinning and compliant spinning. At the same time, many new spinning technologies, such as parallel spinning, air-jet spinning, air-jet vortex spinning, rotor spinning, vortex spinning and friction spinning, are constantly emerging. Combed wool spinning has occupied the international high end, and semi-worsted technology has been pioneered. While wet spinning continues to develop, dry spinning has occupied a place, and silk spinning has also made new development. " However, Academician Yao Mu pointed out that the yarn industry in China still faces a series of constraints, such as shortage of raw material resources, rising labor costs, arduous tasks of energy conservation and emission reduction, and deterioration of the quality of natural fiber raw materials. In order to realize the transformation and upgrading of textile industry, we must constantly innovate in equipment, technology, design and management, adopt new equipment with high automation, less labor and energy saving, attach importance to basic theoretical research and product design, and make full use of the current domestic development.
New equipment helps industrial upgrading.
With the continuous improvement and perfection of textile dyeing and finishing design, the space for creating surprises for the textile industry in the later stage is more and more limited, and fibers and yarns have become a very important part of many links that affect the development of the textile industry. At present, the demand for textile diversification in the textile terminal market is increasing. No matter the innovation of spinning technology or yarn structure, enterprises need to strengthen production and further promote industrial upgrading.
During the meeting, major textile machinery and special equipment manufacturers at home and abroad also brought the latest product information. Participants grasped all kinds of information about the development of the industry, grasped the development trend of the industry in time, extended the idea of product development, and realized the linkage development of the upstream and downstream of the industrial chain.
Rizhao Yuhua Machinery Co., Ltd., as the title unit of this forum, brought Yuhua YF 1 compact spinning equipment and RoCos compact spinning equipment. Chairman Zhang said: "Rizhao Yuhua Machinery Co., Ltd. is a large-scale mechanical processing enterprise integrating production, processing and research and development. The company's main products are spinning frame, upper pin, steel ring, magnetic compact spinning, rice mill screen, foreign trade export processing and other major series of products 150 varieties. In 2008, the company introduced YF 1 negative pressure compact spinning equipment. At present, more than 500,000 spindles in China have used YF 1 negative pressure compact spinning equipment, such as Ningbo Bailong, Linqing Sanhe, Feicheng Longxiang and other enterprises. In the same year, the company cooperated with Swiss Rotocft company to promote the application of RoCos mechanical compact spinning equipment. At present, there are more than 20 customers in China with 350,000 ingots in operation, such as Haian Huaqiang, Demian Group, Shandong Dahai, Sheyang Shuang Shan and other enterprises. "
Li, director of the product department of Rizhao Yuhua Machinery Co., Ltd., introduced in the keynote speech of the forum that Yuhua YF 1 compact spinning equipment has three patented technologies, adopts four-roller structure, has long service life, and the structure has no special requirements for the diameter of anti-twist cots, which is easy to manage and use. In addition, yuhua YF 1 compact spinning adopts an upward suction structure, which has no line of sight obstruction, and follows the conduit design of fluid mechanics, with small conduit resistance and small negative pressure difference before and after; At the same time, the fan adopts frequency conversion control, which is not only convenient for process adjustment, but also beneficial to energy saving and consumption reduction. Continuous innovation and improvement have maintained the technological leading edge of Yuhua YF 1 compact spinning equipment.
RoCos mechanical compact spinning is a widely used negative pressure compact spinning at present. Due to the adoption of mechanical agglomeration, there is no need to add any auxiliary power device, and it can save 500 thousand yuan per 10 thousand spindles, which is the lowest energy consumption compact spinning device at present. At the same time, its mechanical reunion mode makes the device have no wearing parts such as grid rings, gears and bearings. By adopting the structure that the spinning path deviates from the center of the cots, the loss can be reduced by 80 thousand yuan per 10 thousand spindles, which is the compact spinning equipment with the least consumables
Minister Li also introduced that after several years of application practice and improvement, RoCos mechanical compact spinning has been recognized by the market for its good yarn quality and low cost when spinning medium and coarse count yarn. When choosing equipment, enterprises should choose suitable compact spinning equipment and special spinning equipment according to different yarn varieties and quality requirements, so as to obtain the best profit with the lowest input and consumption.
