after having been rapidly growing for more than ten years, china nonwoven fabric industry established a integrated industry chain, which covered specialized fibers, equipment, coiled materials, post finishing adjuvant, products in addition of engineering services as the world’s largest nonwoven producer. currently, the industry has entered a out-pouring period of superfine fiber, composite application technology and high-tech equipment. at the same time, the industry is facing the transform of developing pattern and accelerating power. driven by relying on comprehensive innovation instead of mainly on investment, driven by advanced technology to achieve the improvement of quality and efficiency instead of the scale of expansion, towards of economic growth, environmental friendly, staff career progression and fair competition to the way of the sustainable development instead of pursuit of growth rate.
regarding of technological innovation, the domestic nonwoven enterprises had many breakthroughs. for examples: wet process nonwoven fabric in terms of production speed, applicability of raw materials and product applications have more progression. these productions by this technology such as aramid fiber, glass fiber fabric promoted the development of structure reinforcement and geotechnical construction textiles; with independent intellectual property rights of polyester filament spun-bonded felt base cloth, with its performance advantage to substitute the traditional staple products, it has increased capacity around more than 20 tons in the past two years, effectively promoting the technological progress in the field of building waterproof; high temperature filter material processing technology has achieved the combination of spun bond, needle punching, spun laced, film mulching, post finishing and other processes online. focused on “superfine fiber”, “density gradient”,“fine filtration” and other technical direction has developed many new filtering material; on combination of three production methods of wet-laid paper making, fiber carding, and spun laced entanglement dispersable nonwoven fabric, with dispersed, biodegradable characteristics, its remnant can be used as soil improvement additive, this product which is competitive in cost advantage is used in a vast range of wet towel wipes, baby diaper, women’s health supplies, disposable medical protective supplies, food packaging and other regarding production.
in sorts of intelligence, domestic enterprises introduced the world’s most advanced reifenhouser fourth-generation ssmmms line, truetzschler dry and wet spun laced equipment, dilo needle punching equipment and other products used in the medical and construction field to improve production efficiency and operational stability and product quality. domestic enterprises through the digestion and absorption of imported equipment, combined with the theoretical research, mathematical modeling and repeated practice and innovation, realize the improvement of domestic equipment in terms of stability, efficiency and energy consumption, as well as product quality and performance, part of the equipments and products has reached the international advanced level. such as based on pm2.5 air purification high-efficiency and low-resistance, high temperature filtration materials equipment and, industrial textile key technology, orange-type bicomponent spun laced microfiber leather, with technology used in garment leather production and process technology of pe filament felt base and so on.
