Problems solved by technology

Although the porosity of this filter material has been improved and the water permeability and air permeability have been improved, the strength of the filter material is not very good due to the lack of reinforcement of the base fabric.
In addition, due to the random arrangement of the filter media fibers, the filling density of this filter material cannot be maximized, and due to the uneven density of the fibers, it is easy to reduce the anti-fouling ability of the filter material, and the tightly arranged parts of the filter material are prone to dirt and dirt and are not easy to clean

Abstract

The invention discloses an integral type warp-knitted spacer fabric sterilization filtering material and a preparation method thereof and relates to a filtering material. The integral type warp-knitted spacer fabric sterilization filtering material comprises an upper surface layer, a lower surface layer and a middle connection layer, wherein activated carbon fills the three-dimensional space of the middle connection layer. The preparation method comprises the following steps: firstly weaving an integral type nano-silver fiber warp-knitted spacer fabric; and performing after treatment on the integral type nano-silver fiber warp-knitted spacer fabric. Core fibers of the filtering material warp-knitted spacer fabric are uniform in arrangement, good in pollution resistance and controllable in array density manually, so that the filtering material impurity storing space can be maximized; spaced yarns of the filtering material warp-knitted spacer fabric are arrayed in a 1X1 shape, and the warp-knitted spacer fabric is in a I-shaped structure. The filtering material has the characteristic of deep filtering of a porosity filtering material, is a compound type filtering material integrating surface filtering and deep filtering, is high in filtering efficiency, is good in filtering effect on peculiar smell and particulate matters, and has an excellent sterilization performance and the lasting sterilization capacity.

Description

technical field [0001] The invention relates to a filter material, in particular to an integral warp-knitted spacer fabric sterilization filter material and a preparation method thereof. Background technique [0002] At present, the filter materials for air purification and water purification on the market can be divided into porous filter materials with depth filtration, fabric filter materials with surface filtration and composite filter materials. Most of the porous filter materials are needle-punched and melt-blown non-woven fabrics, which are characterized by loose fibrous tissue, larger particles of impurities are trapped on the surface of the fibers, and fine particles are captured in the deep layers of the filter material, so they have high performance. filtration efficiency. However, the arrangement of the filter media fibers in the three-dimensional space is random, and the filling and storage volume is limited. The surface filtration mode of the fabric filter ma...
