Problems solved by technology

[0003] Public patent CN101332383A although the filter bag also has antistatic properties, its warp and weft yarns are all low-elastic polyester yarns and the antistatic yarns are blended yarns of stainless steel wires and polyester fibers. Such materials are only suitable for low-temperature filtration and cannot be used Filtration at medium temperature and high temperature, and the friction band voltage of the antistatic yarn fabric with stainless steel filaments is significantly higher than that of non-metallic antistatic yarn fabrics, and the

Embodiment 1

[0036] An antistatic base cloth for filter materials, which is woven with PPS yarns with a warp fineness of 240D and a weft fineness of 700D, and an antistatic yarn made by mixing a carbon fiber and PPS staple fiber every 2.7cm in the warp direction Interweave to obtain a plain weave fabric. When weaving, the warp density is set to be 125 threads / 10cm, and the weft density is 65 threads / 10cm. During the weaving process, the yarn before weaving or the base fabric after weaving is heat-set , the technological conditions of the heat setting process are: the heat setting temperature is 85°C, the heat setting humidity is 80%, the number of heat setting times: 1 time, the base fabric is obtained, and its physical properties are shown in Table 1.

Embodiment 2

[0038] An antistatic base cloth for filter materials, which is woven with PPS yarns with a warp fineness of 240D and a weft fineness of 700D, and an antistatic yarn made by compounding a graphite fiber and a PPS filament every 2.7cm in the warp direction Threads were interwoven to obtain a plain weave fabric. The weaving process was the same as in Example 1 to obtain a base cloth. The results of its physical properties were shown in Table 1.

Embodiment 3

[0040] An antistatic base cloth for filter materials, which is woven with PTFE yarns with a warp fineness of 240D and a weft fineness of 700D, and an antistatic yarn made by blending with a carbon fiber and PTFE short fiber every 3.5cm in the warp direction Carry out interweaving, make plain weave fabric, its weaving process is the same as embodiment 1, makes base cloth, and its physical property result is shown in Table 1.

Abstract

The invention discloses anti-static base cloth for a filter material and a production method for the anti-static base cloth. Warp and weft yarns forming the base cloth are high temperature heat-resistant fibers with the fineness of between 260 and 1,500 deniers, and are interwoven with a mixed anti-static yarn consisting of at least one of carbon black fiber and graphite fiber and a high temperature heat-resistant fiber and having the fineness of between 260 and 1,500 deniers at an interval of 2.7-3.5cm in the warp direction, the warp density is 120-180/10cm, the weft density is 20-80/10cm, and the base cloth is manufactured. The base cloth for the filter material has the characteristics of durable anti-static property, dust explosion resistant, high dimensional stability, higher tensile strength, high venting quality, and capacity of prolonging the service life of the filter material.

Description

technical field [0001] The invention relates to a base cloth for filter materials, in particular to an antistatic base cloth suitable for filtering gas-solid, liquid-solid forms, including industrial dust discharge, water treatment, etc., and a production method thereof. Background technique [0002] With economic development and social progress, China will be a country that pays more and more attention to environmental issues. People's awareness of environmental protection has increased, and the concept of environmental governance has shifted from terminal governance to source governance, that is, reducing pollution. For the field of air filtration, more and more coal-fired power plants and waste incineration plants at home and abroad use bag type dust collectors. Bag type dust collectors are one of the most effective technical equipment for controlling industrial dust and smoke at home and abroad, but industrial dust is in When the concentration reaches a certain level, if...
