During the '13th Five-Year Plan' period, the non-woven machinery industry will develop and promote a batch of multi-functional, combined, and differentiated advanced non-woven equipment, which will be included in the 'Thirteenth Five-Year Development Guiding Opinions for the Textile Machinery Industry' Among the 59'key scientific and technological research projects' during the '13th Five-Year Plan' period, there are 5 non-woven machinery projects. During the '13th Five-Year Plan' period, non-woven machinery will move towards modular design, intelligent manufacturing, energy saving and emission reduction, high-yield and wide-width, multiple process combinations, suitable for processing special fibers, composite between multiple materials, simulation and other directions development of. 1. High-speed carding technology research and high-speed carding machine development and application significance and content: in the production process of spunlace, needle punching, hot air and other dry non-woven fabrics, carding machine is one of the essential equipment. The carding technology should be systematically tested and researched to improve the speed and capacity of the carding machine to meet the processing needs of different fiber varieties. The web output speed should reach 200 m/min. Key technologies: optimizing the structure of the carding machine, adopting a modular design, improving spinnability and process adaptability; increasing the amount of new material parts such as carbon fiber and aluminum profiles, reducing equipment weight; improving the level of automation control, and stabilizing product quality. Reduce labor; improve equipment reliability. 2020 goal: the carding machine's web output speed is above 200m/min; compound ratio: 20~80/80~20, fiber fineness ≤2d. 2. The process technology and equipment significance and content of the two-component spunmelt composite non-woven fabric production line: the two-component spunmelt composite non-woven fabric production line is currently the most advanced non-woven fabric equipment in the world, integrating spunbond and meltblown , SMS composite and other core technologies of spinning into webs, and meet the special requirements of multi-die production. This production line combines two high polymers through composite spinning to form PP as the core, PE as the sheath or other structure bicomponent fibers. The fibers are fully drawn and diffused under the action of airflow to form a fiber web, and then hot rolled to produce Spunmelt non-woven fabric. Key technologies: development of spinning box body; development of composite spinning spinneret; development of composite spinning technology; digital distributed control system; closed-loop control system that meets the requirements of production process and safety. 2020 goal: develop and produce PE/PP two-component spunmelt composite non-woven fabric equipment with a width of 3200mm. 3. Significance and content of the high-efficiency, high-yield, environment-friendly and energy-saving air-laid production line: relying on a new aerodynamic method to air-laid waste spun fibers into felts, which can replace traditional mechanical production processes represented by carding machines and cross-laid machines. The production line is equipped with a full-process pressure control device to make the fiber web layer uniform in the entire length and width directions, and the maximum density difference is less than 3%. The production capacity of the production line is more than 1000 kg/h. Key technology: research on airlaid technology based on aerodynamics; research on web uniformity control technology. 2020 goal: breakthrough key technologies, production capacity of 1000 kg/h, finished product weight of 150-2000 g/m2, and establishment of a demonstration production line. 4. Significance and content of PP spunbond needle-punched geotextile production line: PP spunbond needle-punched geotextile has better acid and alkali resistance, higher tensile strength and elongation than PET geotextile, and has more applications in the geotechnical field. It is better than PET geotextile, especially for civil engineering and airport runway construction under saline-alkali geological conditions. Its characteristics cannot be replaced by PET spinning clay work cloth, and its technology and products are still blank in China. Key technology: PP spunbond needle-punched geotextiles are different from ordinary PP spunbond hot-rolled non-woven fabrics. Generally, raw materials with relatively lower melt index are used, and the fiber size is larger, generally about 10d. Because PP has a large hot melt value and a low surface friction coefficient, in the spunbond production process, it is necessary to solve the difficult problems of fiber cooling, air drafting, laying and needle-punching consolidation, etc. 2020 goal: complete the web The production line with a width of 4.5 meters or more was put into the market. 5. Significance and content of the digital control dust filter material production line: In recent years, the domestic acupuncture process technology has gradually matured, but compared with the advanced level of foreign countries, the domestic equipment has a low degree of automation, a low production capacity and a low quality rate of finished products. Develop a special numerical control system for non-woven equipment (needling equipment), which is used in the production line of high-temperature resistant fiber dust filter material, and is used for air feeding machines, high-speed messy non-woven carding machines, cross-folding netting machines, The wide-width and high-frequency acupuncture machine has been developed and optimized to solve the problems of high-speed acupuncture frequency, high-precision mechanism movement, and intelligent control system. Key technologies: multi-mechanism synchronous servo speed control; intermittent precise servo motion control; reciprocating two-way (horizontal-longitudinal) combined process control; modular design of structural design; dedicated numerical control system. 2020 goal: independent development of non-woven dust filter material production line, the technical level has reached the international advanced level, and the formation of relevant technical standards.
