Composite dust removing and odor removing filtering cloth

Abstract

The invention relates to the technical field of needle felts, particularly to a composite dust removing and odor removing filtering cloth, which comprises a filtering cloth body, wherein a first support layer is arranged on the upper side of the filtering cloth body, a second support layer is arranged on the lower side of the filtering cloth body, the upper side of the first support layer is provided with a PPS short fiber layer, the upper side of the PPS short fiber layer is provided with an antistatic layer, the upper side of the antistatic layer is provided with a functional layer, and theupper side of the functional layer is provided with a powder barrier layer. According to the present invention, the filtering cloth body is prepared by interweaving ultra-high molecular weight polyethylene fiber warp and ultra-high molecular weight polyethylene fiber weft, such that the advantages of high precision, strong load and good tensile strength can be achieved, the service life is more than 3 times the service life of the common chemical fiber, the dry heat shrinkage rate is less than 2%, the acid resistance, the alkali resistance, the wear resistance, the tensile strength and servicelife are improved, the use range of the filtering cloth is expanded, the filtering quality is improved, and the filtering cost is reduced.

Description

technical field [0001] The invention relates to the technical field of filter cloths, in particular to a composite dust-removing and odor-removing filter cloth. Background technique [0002] Filter cloth is a filter medium woven from natural fibers or synthetic fibers. Including metal mesh or filter, mainly used in air filtration and dust removal, dust collection powder to purify the air, protect the environment, in smelters, chemical plants, sugar, dyes, medicine, food and other industries. Filter cloth, a filter medium made of natural fibers or synthetic fibers, commonly used materials are cotton, hemp, wool, cocoon silk, asbestos fibers, glass fibers and some synthetic fibers, such as cotton canvas, twill and wool woolen cloth etc. In a broad sense, filter cloth also includes metal mesh or filter screen. Synthetic fibers mainly include polypropylene, polyester, nylon, vinylon, etc. Among them, polyester and polypropylene are the most commonly used for solid-liquid sepa...

Problems solved by technology

[0003] In the prior art, the filter bag body of the same style is usually made of a filter cloth of one specification. Since the filter cloth has a small pore size, it can achieve a good filtering effect, but the filter cloth with too small pore size is easy to Blocked by dust, it is not easy to prolong its service life
