High-temperature resistant no-woven filter cloth with monofilament-woven net as base cloth and manufacturing method thereof

Abstract

The invention discloses a high-temperature resistant no-woven filter cloth with a monofilament-woven net as a base 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 with the monofilament-woven net as the base 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 non-woven filter cloth with a monofilament woven net as the base 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 bei...
