Problems solved by technology

[0002] At present, industrial non-woven filter cloth is widely used in the filtration process of high temperature and harsh working conditions in smelting, chemical industry, building materials, thermal power, garbage incinerators, coal-fired boilers and other industries. One of the common shortcomings of these filter cloths is that they cannot Can withstand the high temperature environment in the filtration production process, resulting in a short service life of the filter cloth and increased production costs

Embodiment Construction

[0026] Embodiments of the invention are described in detail below, examples of which are shown in FIGS. 1 and 2 . The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0027] In the present invention, a kind of high temperature resistant fiber non-woven filter cloth and its manufacturing method are provided with monofilament woven net as base cloth, described filter cloth is made up of two-layer structure, namely: base cloth layer (accompanying drawing 2 in 1) and filter layer (4 in attached drawing 1). The base fabric layer is a woven net structure in which the warp and weft yarns of chemical fiber monofilament raw materials are interwoven (see attached figure 2 shown, with figure 2 1 in is the meridian direction, attached figure 2 2 in the latitudinal direction). The warp and weft interlaced woven net base cloth layer only plays the role of suppo...

Abstract

The invention discloses a high-temperature resistant no-woven filter cloth and a manufacturing method thereof. The filter cloth is composed of a base cloth layer and a filter layer. A specific process route comprises the following steps of: selecting 100% of basalt short fibers for later use; selecting a woven net by taking nylon 6 filament fibers as warps and wefts for later use; placing the basalt short fibers into a cotton blender machine to be subjected to cotton blending, then carrying out opening treatment in an opening machine; then feeding raw material after opening into the cotton blender machine to be subjected to fine cotton blending; then feeding a carding machine to be carded into a net shape; then placing the carded net-like fibers into a lapping machine, and lapping to obtain a fibrous layer; combining the fibrous layer after lapping with woven net fabric into a whole by utilizing a needling machine; and then calendaring on the surface of a basalt short fibrous layer. The high-temperature resistant no-woven filter cloth disclosed by the invention has excellent high-temperature resistant property, and the contradictions and problems that the traditional single woven filter cloth is low in efficiency and easy to deform and a single non-woven filter cloth is insufficient in strength and easy to be broken are solved.

Description

technical field [0001] The invention relates to a filter cloth, in particular to a high temperature resistant fiber non-woven filter cloth and a manufacturing method thereof. Background technique [0002] At present, industrial non-woven filter cloth is widely used in the filtration process of high temperature and harsh working conditions in smelting, chemical industry, building materials, thermal power, garbage incinerators, coal-fired boilers and other industries. One of the common shortcomings of these filter cloths is that they cannot Can withstand the high temperature environment in the filtration production process, resulting in a short service life of the filter cloth and increased production costs. Contents of the invention [0003] Based on the above technical problems, it is necessary to provide a filter cloth, which not only has the strong and durable performance of woven filter cloth, but also has the performance of being able to withstand high temperature and ...
