Embodiment Construction

[0019] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] Such as figure 1 with figure 2 As shown, the filter cloth used in the production of white carbon black provided by the present invention is woven by warp 2 and weft 1, the warp 2 is multifilament, and the weft 1 is monofilament. Among the warp and latitude intersections of the cloth, the number of warp and latitude intersections where the weft 1 is above the warp 2 is greater than the number of warp and latitude intersections where the weft is below the warp.

[0021] In this way, the top of the filter cloth can be used as a filter surface, and the bottom of the filter cloth can be used as a non-filter surface. There are many weft threads 1 arranged on the filter cl...

Abstract

The invention relates to the technical field of filter cloth, and in particular relates to filter cloth for producing white carbon black. The filter cloth for producing white carbon black is formed by weaving warps and wefts; the warps are multifilaments; the wefts are monofilaments; in the wrap and weft cross points of the filter cloth, the number of the warp and weft cross points of the wefts above the warps are larger than that of the warp and weft cross points of the weft below the warp; and therefore, the number of the monofilaments arranged on the filter cloth is large, so that the adhesive force of a filter cake is reduced, the permeation volume of the filter cloth is increased, the amount of workers is reduced, and simultaneously the number of the multifilaments arranged below the filter cloth is large, so that the strength of the filter cloth is improved, the service life is prolonged, and the cost of the filter cloth is reduced.

Description

technical field [0001] The invention relates to the technical field of filter cloth, in particular to a filter cloth used in the production of white carbon black. Background technique [0002] At present, a filter press is required in the production of white carbon black, and a filter cloth is required in the filter press, and the reacted solution is filtered in the filter press and then filtered into a cake on the filter cloth. The existing white carbon black filter cloth is usually divided into two categories: one is multifilament filter cloth, which is woven with many fine fibers, spun into thread, and woven into cloth according to a certain weaving method; the other is monofilament filter cloth. Filter cloth, warp and weft threads are all made of one silk, and woven into cloth according to a certain weaving method. Multifilament is a kind of chemical fiber filament, which is a twisted or untwisted bundle formed by combining filaments spun out of a porous spinneret. Mon...
