Composite efficient air filtration material

Abstract

The invention discloses a composite efficient air filtration material. The composite efficient air filtration material comprises a filter surface layer, a melt-blowing filter layer and a woven filterlayer; the woven filter layer, the melt-blowing filter layer and the filter surface layer are stacked from inside to outside; the filter surface layer is formed by warp and weft knitting of a carbon fiber core spun yarn by adopting plain weave; the carbon fiber core spun yarn is 36D; the melt-blowing filter layer comprises polypropylene mesh cloth and a nonwoven filter layer melt-blown on the polypropylene mesh cloth; the polypropylene mesh cloth is woven mesh cloth woven from a polypropylene yarn by adopting leno weave; the nonwoven filter layer is formed by interweaving melt-blown polypropylene fibers; the woven filter layer is a weft knitting mesh grid fabric; the woven filter layer is woven from a fine denier polypropylene yarn. The composite efficient air filtration material has the advantages that the structure is reasonable, a multilayer stacked composite structure is adopted, and the filter surface layer, the melt-blowing filter layer and the woven filter layer are organicallycombined to form the efficient air filtration material with small filter resistance, high filter efficiency, good structural stability, easy cleaning and long service life.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a composite high-efficiency air filter material. Background technique [0002] Due to the intensification of environmental pollution in our country, sandstorms and smog have appeared in major cities in recent years, which has greatly threatened people's health. The continuous improvement of people's requirements for air quality and the promulgation and implementation of a series of strict environmental protection regulations have made air filtration the fastest growing part of the world's filtration market; at the same time, with the development of high-tech industries at home and abroad, the demand for air filtration equipment The field of application is developing rapidly, and the research and development of the filter material, which is the core of filter equipment, has also received unprecedented attention. [0003] Air filter materials are mainly divided into woven filter materials ...
