Wet forming technology originated from the paper industry.
In paper production, fibers are suspended in an aqueous solution.
The water flows out of the flat mesh while the fiber material remains on the mesh to form a uniform sheet, which is then bonded, dried, finished and wound. Japanese wet-laid non-woven fabric is one of its derivative products.
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 is complex and the plant construction and equipment investment costs are high. , The spinning speed is low, so 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.
