Base cloth for filter material and method of manufacturing the same

Abstract

The invention discloses a cheb used on filtering material and the production method. When the measured pressure of the product is 125Pa according to JIS L 1096 8.27.1A standard, the venting quality value of the cheb is 300cc / cm2 / s to 600cc / cm2 / s; according to JIS L 1096 8. 12. 1A standard, the warp direction of the tensile strength of the cheb is 500N / 5cm to 1000N / 5cm, and the direction of weft is 300N / 5cm to 800N / 5cm. The production method comprises the procedures of choosing warp and weft yarn fiber, weaving and so on; During the process of weaving, the yarn before weaving and the cheb after weaving is processed by heat setting and controls the indexes of warp and weft density, tilter and twist. The invention has good tension strength and venting quality, which improves the filtering performance of the filtering material and prolongs the service life of the filtering material.

Description

Technical field: [0001] The invention relates to a base cloth for filter materials, which is suitable for the filtration of gas-solid, liquid-solid and other forms, including the filtration of industrial smoke and dust, the filtration of water treatment and the like. Background technique: [0002] With the increasingly stringent environmental standards, the country's requirements for air emissions and water emissions are also becoming more and more stringent. For the field of air filtration, more and more coal-fired power plants and waste incineration plants at home and abroad use bag filter. The bag filter is one of the most effective technical equipment for controlling industrial dust and smoke at home and abroad. The development of bag filter also promotes the progress of filter material, and the requirements for filter material performance, including filtration efficiency, application range, service life, and filter material strength, are also increasing, which will als...

AI Technical Summary

Problems solved by technology

The tensile strength of the base fabric is low, and it is easy to be damaged when dust is washed and cleaned; and the air permeability value also affects the filtration efficiency and filtration resistance of the filter material

Improving the air permeability of the filter material can reduce the filtration resistance and prolong the service life of the filter material, but at the same time it will reduce the filtration efficiency of the filter material and increase the emission concentration, which cannot meet the environmental protection requirements.
