Nonwoven technology is a kind of fiber material processing technology derived from textile, chemical fiber and papermaking. With its rapid development, domestic and foreign enterprises and relevant scholars have conducted a lot of research on the networking technology and reinforcement technology of non woven. This paper looks forward to the development trend of non woven fabric reinforcement technology.

1.Acupuncture reinforcement technology of non woven

Although the acupuncture reinforcement technology in China has developed rapidly and the application scope of acupuncture non woven has been expanding, there are still some problems, such as high energy consumption, narrow width, low output, poor process flexibility, lack of innovation consciousness and so on. In the future, China should increase the research and development of acupuncture equipment with high frequency, shock absorption, width, personalization and wide applicability, optimize the design and lightweight design of the acupuncture mechanism, and introduce vibration compensation elements to greatly improve the acupuncture frequency; In order to meet the needs of high-speed and efficient needling processing, the needling equipment with elliptical trajectory and circular trajectory should be two major development trends, so it is necessary to increase R & D investment; We should vigorously develop universal acupuncture and develop the technology of online replacement of needle plate, so as to greatly improve the versatility and durability of acupuncture equipment; Acupuncture equipment manufacturing enterprises should pay attention to green, energy saving and environmental protection while achieving high efficiency, so as to realize the sustainable development of the nonwoven industry; Increase the research and development of special production technology for imaging CNC needling nonwovens, and develop a CNC intelligent system for needling equipment.

2.Spunlaced reinforcement technology of non woven

China's spunlaced nonwovens improve their market competitiveness mainly by expanding production scale and reducing costs, but they have less investment in technological innovation and product research and development, and there is still a large gap with the world's advanced level. Therefore, we should increase the scientific research investment and professional training in the field of spunlaced nonwovens, improve the ability of professional technological innovation and product development, and develop high-performance Spunlaced non woven special production equipment and fiber raw materials; Vigorously develop the production line combining Spunlaced and spunbonded with other nonwoven technologies to achieve a breakthrough in isotropic spunlaced nonwoven materials; Develop high-speed and high-yield Spunlaced equipment with high automation, energy-saving and emission reduction effects, high-efficiency and energy-saving drying technology and zero discharge water treatment technology, and develop an environment-friendly spunlaced nonwovens production line that can disperse and degrade.

In the future, China's Spunlaced industry will gradually transform and upgrade from extensive to intensive, and from low value-added to high value-added. Among them, Spunlaced equipment is developing in the direction of high speed, high efficiency, high yield, wide width, energy saving and intelligence, further reducing the cost of spunlaced products; Spunlaced raw materials are developing in the direction of differentiation to meet the needs of different products; In order to make up for the limitations of spunlaced products, the process flow gradually adopts Spunlaced Composite Technology and functional finishing technology; Spunlaced products will develop in the direction of diversification, functionality, reliability and durability, and further expand the application field of products.

3.Hot air reinforcement technology of non woven

Hot air non woven has the advantages of uniform appearance, softness, fluffy and elasticity, and does not contain any chemical substances, such as adhesives. In recent years, with the expansion of disposable sanitary products market, the demand for hot air nonwovens has increased rapidly. In the future, the hot air reinforcement technology should be developed on the basis of multi category, low energy consumption and functional thermal adhesive fibers; Pay attention to the development of high viscosity fibers, and use low processing temperature, wide processing range and high processing speed to meet the needs of high-speed and efficient production; Develop differentiated low melting point fibers such as ultra-fine fibers, hollow fibers and easy to dye fibers, so as to improve the economic benefits of products and broaden the application fields; Promote the technological progress of functional multi gradient thermal bonding technology and equipment, and realize the development of green process by reducing energy consumption, saving resources and costs.

In recent years, non woven reinforcement technology and equipment at home and abroad have made many achievements in high-speed, high-yield, high-performance, networking, systematization and so on. The reinforcement technology and equipment research and development dedicated to non woven fabric with high-speed, wide width, personalization and wide adaptability are still the development direction in the future. Under the principle of low investment and low cost, the research on low energy consumption of high-frequency needling technology and Spunlaced technology and the research on high-speed and low energy consumption of thermal bonding reinforcement technology are the focus of future research and development.
