Abstract

The invention discloses a filtering fabric having three-dimensional structure and a preparation method thereof. The fabric comprises an upper surface yarn layer and a lower surface yarn layer composedof warp yarn and weft yarn, and a spacing layer composed of interval yarn between the upper surface yarn layer and the lower surface yarn layer, and a part between the spacing layer as well as the upper surface yarn layer and the lower surface yarn layer is filled with a filtering material. The preparation method comprises the following steps: weaving the upper surface yarn layer and the lower surface yarn layer, wherein each surface yarn layer comprises two layers of warp yarn and a layer of weft yarn, then employing two groups of spacing yarns for mutual interlacing, binding the upper surface yarn layer and the lower surface yarn layer to form an integral body; weaving a hollow spacing layer with the filler, after weaving, immersing the three-dimensional fabric in a mixed solution of araising agent and a compatilizer, performing immersing of the mixed solution in the filler for decomposition to generate the foams having micro explosion effect, gradually loosening and swelling the structure of the filler to fill the whole three-dimensional hollow structure, and obtaining the filtering fabric having three-dimensional structure. The three-dimensional interval fabric is taken as aframe support material, and provides an accommodation space and mechanical support for a fluffy carbon tube material.

Description

technical field [0001] The invention relates to a filter fabric with a three-dimensional structure and a preparation method thereof, belonging to the technical field of filter materials. Background technique [0002] With the development of industry, air pollution and water pollution are more serious. In some heavy industrial enterprises, acidic or alkaline gases in high-temperature exhaust gas have a great impact on air quality. Therefore, the research and application of filter materials such as filter screens, filter felts and filter fabrics are relatively extensive. Textiles for filtering debris from gases or liquids. There are two types of wet filtration and dry filtration. The separation of solid particles in the liquid is called wet filtration, and it is mostly used in industries such as chemical industry, paint, dye, pigment, petroleum, ceramics, sugar and food. Purifying air and separating dust and smoke in gas is called dry filtration, and it is mostly used in m...
