Abstract

The invention relates to a manufacturing method of a high-filtration anti-static tectorial membrane composite needled felt, which is characterized in that the composite needled felt is formed by that after being treated with anti-static processing, a composite needled felt plain felt is treated with hot pressing draping with a polyfluortetraethylene microporous membrane. The composite needled felt has good anti-static performance, high filtration efficiency and strong folding endurance, and the service life of the composite needled felt is greatly prolonged.

Description

technical field [0001] The invention relates to a method for manufacturing a high-filtration, antistatic film-coated composite needle-punched felt, which belongs to the field of glass fiber filter materials used for manufacturing industrial flue gas filter products. Background technique [0002] At present, the traditional needle-punched filter materials at home and abroad adopt non-woven needle-punched technology and composite technology, and most of them have a three-dimensional interlaced structure, which can give full play to the dust-catching function of the fiber, and the dust-catching effect is stable; the needle-punched felt has no or only a small amount (with Base cloth) twisted warp and weft yarns have small pores, large porosity, uniform distribution, and a total porosity of 70-80%, which is 1.6-2 times that of general woven filter materials, so it has good air permeability and resistance Low. However, the filtration efficiency of ordinary needle felt filter mate...
