specific Embodiment

[0009] A high-temperature-resistant filter cloth, which is woven from warp 1 and weft 2, the warp 1 and weft 2 are made of 20s / 2 aramid single yarn, and the warp 1 and weft 2 are woven into 5 / 2 warp satin weave structure.

[0010] The reason why strands are used is that the aramid single yarn does not have strong and weak twists, and the cloth surface has a better style; the other is that the warping is easy to unwind in the axial direction.

[0011] According to the theoretical calculation strength, the warp strength is 1215N, and the weft strength is 878N. The heat shrinkage of the filter cloth in the warp and weft is below 0.4%.

Abstract

The invention relates to a high-temperature-resistant filter cloth, which belongs to the field of textile industry. A high temperature resistant filter cloth, which is woven from warp and weft, the warp and weft are both processed from 20s / 2 aramid single yarn into strands, and the warp and weft are woven into 5 / 2 warp satin organizational structure. The warp and weft of the filter cloth are all made of aramid yarn, which makes the filter cloth have strong high temperature resistance and greatly improves the use effect and life of the filter cloth.

Description

technical field [0001] The invention relates to a high-temperature-resistant filter cloth, which belongs to the field of textile industry. Background technique [0002] In industries such as iron and steel, metallurgy, and power plants, dust removal equipment is required to ensure that the smoke discharged into the atmosphere meets the requirements of energy conservation and environmental protection. At present, most of the filter cloths for dust removal in these dust removal equipment are filter cloths with the same gaps woven from glass fibers. However, the temperature resistance of glass fiber is poor. When the working temperature reaches about 200°C, the working effect and life of the filter cloth will be greatly shortened. To this end, we provide a high temperature resistant filter cloth, the warp and weft of the filter cloth are all made of aramid yarn, which makes the filter cloth have strong high temperature resistance, greatly improving the use effect and life of t...
