Embodiment Construction

[0007] Steps:

[0008] 1. Base fabric weaving:

[0009] The grammage is 600g / m by weaving with pure tass fiber yarn by loom 2 Metas fiber loom cloth, ready for use.

[0010] 2. Opening

[0011] Mix 1000kg of polyester, 150kg of acrylic fibers and 150kg of PPS fibers, place them in an opener, mix and open them evenly, and set aside.

[0012] 3. Combing

[0013] The opened acrylic fiber, PPS fiber and polyester fiber are carded and combed to form a mixed net layer.

[0014] 4. Laying net

[0015] Lay the mixed net layer on the two outer sides of the Metas fiber loom cloth respectively.

[0016] 5. Felting

[0017] Pre-stabbing is performed on the laid net first, and then the main stabbing is performed to make a semi-finished felt.

[0018] 6. The semi-finished felt is singed, calendered, and finally heat-set to form a composite filter material non-woven fabric.

[0019] 7. According to the needs, cut the composite filter material non-woven fabric to make block composite...

Abstract

The invention discloses a production method of a compound filter material, relating to environmental-protection treatment, in particular to the technical field of filtering. The compound filter materials is produced by laying two surface layers on both sides of an intermediate layer, acupuncturing into a felt, and then singeing, calendaring and thermally forming, wherein the intermediate layer is a nomex fiber loom fabric, and the surface layers are formed by mixing acrylic fibers, PPS fibers and polyester fibers and the lapping. The non-woven fabric produced by the invention has the advantages of high surface smoothness, can ensure that gas and solid of the filter material are completely separated, and has the advantages of high abrasive resistance, bending resistance as well as acid and basic resistant chemical property, and long service life.

Description

technical field [0001] The invention relates to environmental protection treatment, in particular to the technical field of filtration. Background technique [0002] When controlling air pollution, in order to collect toxic and harmful gases such as ultrafine dust, a large number of filtering equipment is required. [0003] The filter material in the filter equipment in the existing market can only be used in the working environment of 130 ℃ ~ 150 ℃, and the service life is short, and the corrosion resistance is poor. If the high temperature filter material is used instead, the cost is high and it is too wasteful. Contents of the invention [0004] The purpose of the present invention is to invent a composite filter material capable of high temperature resistance and corrosion resistance. [0005] In the present invention, two surface layers are auxiliary arranged on both sides of the middle layer, which are felted by needle punching, singeing, calendering, and heat setti...
