Abstract
The invention discloses a double-layer heterogeneous high-temperature-resistant woven filter cloth and a manufacturing method thereof. The filter cloth consists of a base cloth layer and a filter layer, wherein the base cloth layer is of a woven net structure formed by six nylon monofilament fibers which are longitudinally and latitudinally interlaced, the filter layer is of a woven cloth structure formed by an inorganic basalt short fiber, the raw material of the filter layer is 100% inorganic basalt short fiber, the woven net as the base cloth layer is of a longitudinally-latitudinally-interlaced woven net tissue structure, and both the warp yarn and the weft yarn are chemical fiber polypropylene and/or nylon monofilament fibers. The woven filter cloth is realized in a double-layer heterogeneous linkage weaving manner, and then, the surface of the filter layer is subjected to calendaring to enable the surface of the filter layer to be smooth and flat. The double-layer heterogeneous high-temperature-resistant woven filter cloth disclosed by the invention has excellent high temperature resistance, and can still continuously and normally work in the environment under a temperature of 500 DEG C-700 DEG C.
Description
Technical field
The present invention relates to a kind of filter cloth, specifically, is high temperature resistant Woven filter cloth of a kind of double-deck isomery and manufacturing approach.
Background technology
At present; In the filtration operation of the working condition that industry high temperature such as industrial Woven filter cloth is widely used in smelting, chemical industry, building materials, thermoelectricity, incinerator, coal-burning boiler are abominable; The ubiquitous deficiency of these filter cloths is can not bear in the filter process up to the hot environment more than 500 ℃, causes service life of filter cloth of short durationly to be risen with production cost.
Summary of the invention
Based on above-mentioned technical problem; A kind of filter cloth need be provided; This filter cloth had both had the sturdy and durable performance of Woven filter cloth; Have the performance that can tolerate the high temperature more than 500 ℃ again,, the invention provides high temperature resistant Woven filter cloth of a kind of double-deck isomery and manufacturing approach thereof for realizing above-mentioned purpose.The present invention is for realizing above-mentioned purpose; Realize through following technical scheme: said Woven filter cloth is made up of double-layer structure; That is: base cloth layer and filter course; Described base cloth layer is that nylon 6 monfil are the woven net structure that longitude and latitude interweaves, and described filter course then is the woven cloth structure that is made up of inorganic basalt short fiber, and wherein the employed raw material of filter course is 100% basalt short fiber; Woven net as base cloth layer is the woven net institutional framework that longitude and latitude interweaves, and its warp thread and weft yarn are the chemical fibre polypropylene fibre and/or the nylon monofilament fiber of monofilament structure, and said Woven filter cloth adopts the access node weaving mode of double-deck isomery to realize; Then, the calendering processing is carried out on the surface of said filter course again, makes its smooth surface and smooth.
High temperature resistant Woven filter cloth of a kind of double-deck isomery of the present invention and manufacturing approach thereof, its process route is following:
1, choose 100% basalt short fiber, denier range: 12.5tex-22 tex, (6-24 thigh), as the warp thread and the weft yarn of filter course, subsequent use.
2, choose denier range be 11.9tex-16.5 tex, the fibre section is shaped as chemical fibre polypropylene fibre and/or nylon fibre circular, monofilament structure, and is as the warp thread and the weft yarn of base cloth layer woven net, subsequent use.
3, above-mentioned subsequent use basalt short fiber is processed one through axle through warping machine, in order to warp thread as filter course.
4, above-mentioned subsequent use basalt short fiber is processed through the beam barrel yarn through whole bobbin-winding machine, in order to weft yarn as filter course.
5, the chemical fibre polypropylene fibre and/or the nylon fibre of above-mentioned subsequent use monofilament structure are processed another through axle through warping machine, in order to warp thread as base cloth layer.
6, the chemical fibre polypropylene fibre and/or the nylon fibre of above-mentioned subsequent use monofilament structure are processed through the beam barrel yarn through whole bobbin-winding machine, in order to weft yarn as base cloth layer.
7, two above-mentioned warp axles are gone up machine, a denting, gaited.
8, machine on two kinds of above-mentioned tube yarns is used as weft yarn.
9, then, adopt the loom of double ends axle construction to carry out weaving of two-layer fabric.
The calendering processing is carried out on the basalt short fiber layers surface that 10, will be made into fabric.
This shows; In technique scheme of the present invention; The woven filter course that described inorganic basalt short fiber constitutes is being born filtering function, and inorganic basalt fibre is a mineral fibres; Has good resistance to elevated temperatures, operate as normal continuously still under-250 ℃～700 ℃ environment; The woven net as base cloth layer that monfil constitutes then has mechanical strength, fracture strength and the excellent percentage elongation that is higher than conventional woven cloth, can deform hardly.Said filter course and base cloth layer are combined as a whole through the weaving mode of access node.The high temperature resistant Woven filter cloth main performance of described this double-deck isomery is a bit as follows: high temperature resistant: inorganic basalt fibre is a mineral fibres, has good resistance to elevated temperatures, operate as normal continuously still under 780 ℃ environment, and do not burn.
Filter cloth of the present invention compares to the Woven filter cloth that generally uses at present, has good resistance to elevated temperatures, is specially adapted to smelt, in the filtration operation of industry worst hot case conditions such as chemical industry, building materials, thermoelectricity, incinerator, coal-burning boiler.
