Japanese wet-laid non-woven fabrics have a high production speed, which can reach 400m/min. It is suitable for short fibers with a length of 20mm or less to form a web; there is almost no limit to the mixing of different quality fibers; the fibers in the web are arranged randomly, and wet-laid non-woven fabrics The material is almost isotropic; the product has good fluffiness and fiber web uniformity; the production cost is low; the possibility of changing the variety of wet-laid nonwoven materials is small; and the water consumption is large.
Japanese wet-laid non-woven fabrics not only require a wide variety of bulky dope preparation and pre-spinning preparation equipment, but also coagulation baths, circulation and recovery equipment. The process flow is complex, and the investment in plant construction and equipment is high. The spinning speed is low and therefore the cost is higher.
When manufacturing segmented fibers, spinnerets with tens of thousands of holes or integrated spinnerets can be used to increase production capacity.
Generally, only synthetic fibers that cannot be melt spun, such as polyacrylonitrile fibers and polyvinyl alcohol fibers, are suitable for wet spinning of polymer solutions to produce segmented fibers and filament bundles.
Suzhou ptfe filter membrane manufacturer supplies Japanese wet-laid non-woven fabrics, polyester spunbond non-woven fabrics, polypropylene spunbond non-woven fabrics and other non-woven fabrics, which can be widely used in air filtration, packaging materials, medical tapes, cable wrapping , biofilm and other fields.
We have a full set of advanced production equipment and technology, as well as an advanced clean room and an independent composite slitting workshop to ensure the production quality of ptfe film; the product materials produced are all imported raw materials, with high uniformity and high performance Stable, good breathability, filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
