We proSeries of polyester needled felt non-woven filter media using acupuncture techniques, and by the heat-setting and other treatment methods are made widely used industrial catch dust, dust control and so on. Polyester needled felt has good air permeability and after heat treatment, surface smooth, it is not easy deformation, easy cleaning.
duces high-quality manufacturers of polypropylene fiber polypropylene needle felt filter. In addition to its ordinary needle felt some of the advantages of filtering, the result of PP more than polyester fiber excellent acid, alkaline and low softening point, the polypropylene used in flue gas temperature needled felt generally below 100â and acid, occasions higher alkalinity or acidity alkalinity larger the field of liquid-solid separation. And frame filter, vacuum filter, bag filter, centrifugal filter liquid filter, such as supporting the use of separation equipment. Liquid-solid separation for the polypropylene fiber polypropylene carpet fibers with different specifications, and general or high-strength yarn fabric manufacturer enhanced, can be dealt with by the hot-rolled hair on fire.
