In recent years, the level of industrial molding technology and non-woven equipment in my country has been continuously improved, especially in the production speed and width. For example, the speed of the complete set of sms non-woven equipment has exceeded 400m/min, and the maximum width can reach 7m; The needle frequency of the needle punching machine can reach up to 2000 rpm, breaking through the complete set of non-woven equipment for spunbond filter material and the complete set of processing equipment for spunlace felt filter material. The effective width of the ultra-wide projectile loom can reach 7.4m, and the weight It can reach 1500g/㎡, which is especially suitable for the weaving of ultra-wide, high-density, and heavy-duty industrial fabrics. The successful development of multi-axial warp knitting equipment has greatly improved the tensile strength, elastic modulus, and tear resistance of fiber fabrics. It has the characteristics of strong designability, good raw material adaptability, low production cost and high production efficiency. Multi-axial warp knitted fabrics, as the reinforcement of composite materials, are now widely used in many fields such as wind power generation, aviation, aerospace, transportation, construction and engineering.
The industry has made many breakthroughs in the localization of special non-woven equipment such as single-function finishing and supporting equipment. For example, the post-finishing equipment for non-woven fabrics has industrialization capabilities, and the dynamic processing equipment for PTFE foam layers has improved filtration accuracy. , To reduce energy consumption, the domestic 5500mm ultra-wide intelligent setting machine solves the problem of large temperature difference of wide fabrics and so on.
