Filtering cloth woven from monofilaments and multifilaments

Abstract

The invention discloses filtering cloth woven from monofilaments and multifilaments, relating to the field of industrial filtering cloth. Monofilaments and multifilaments are interwoven, the multifilaments completely float on the surface of the entire cloth so as to play a favorable interception role, when materials enter to the interior of the cloth, a favorable filtering effect can be achieved because the interior of the cloth are completely the nomofilaments which have favorable permeability, and thus, the service life of the filter cloth is prolonged. In addition, the design method can be used for fully exerting the strong force effect of the two yarns, the requirement on the industry for high load bearing of the filter cloth is met, 3 / 11 / 3 composite tissues are adopted and have long floating line yarns, so that a smooth surface effect is achieved, and thus, cake discharging after filtering is facilitated and no material is stuck to the filter cloth.

Description

technical field [0001] The invention relates to a monofilament woven filter cloth, which relates to the field of industrial filter cloth. Background technique [0002] At present, most of the woven filter cloths in the domestic market are composed of multifilament and short fibers. During use, the suspension is in contact with the filter cloth, and the solid particles smaller than the pore size of the filter cloth pass through the filter cloth under the action of pressure, and the particles larger than or equal to the pore size of the filter cloth are trapped on the surface of the filter cloth to form a layer of filter cake, and then The gradually thickened filter cake continues to trap particles, thereby achieving solid-liquid separation. In the fine iron ore industry, the strength requirements for the filter cloth are relatively high, but the filter cloth composed of multifilament and short fiber has the following problems in the use process: 1. It is easy to block when t...

Problems solved by technology

In the fine iron ore industry, the strength requirements for the filter cloth are relatively high, but the filter cloth composed of multifilament and short fiber has the following problems in the use process: 1. It is easy to block when the material opening exceeds a certain value; 2. Bacteria are easy to breed; 3, the service life is short, and the regeneration ability is poor; 4, the filter cake and the filter cloth have poor peeling performance, and the general woven filter cloth cannot filter the material with a large thickness, which makes it difficult to filter the material with a large particle size. low efficiency and high cost
