The definitions of Japanese wet-laid non-woven fabrics and dry-laid non-woven fabrics are completely different in terms of production equipment, technology, and raw materials. Let’s learn more about them together.
Japanese wet-laid non-woven fabrics: The fiber raw materials placed in the water medium are opened into single fibers, and different fiber raw materials are mixed at the same time to form a fiber suspension slurry. The suspension slurry is transported to the web-forming mechanism, and the fibers are wet In this state, it is formed into a net and then reinforced into a cloth.
Dry-laid non-woven fabric: It is a non-woven fabric made by dry-laid short fibers to form a “fiber web” and then reinforced by mechanical, chemical or thermal processing methods.
It has the widest scope of inclusion and is the earliest category of nonwovens.
The web fixing processes used include thermal bonding methods (including hot melt method, hot rolling method), mechanical web fixing methods (including acupuncture method, jet web fixing method); “chemical bonding method” (including impregnation method) , spray method, foam method, printing method, solvent method).
It is a manufacturer of polytetrafluoroethylene microporous membranes that specializes in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
In addition, ptfe filter membrane manufacturers also supply 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, cables Packages, biofilms and other fields.
The company can provide samples and arrange sales staff to provide door-to-door service if there are other requirements.
