Embodiment Construction

[0034] According to the performance of various fibers, choose different collocations to meet the needs of various industries or working conditions. According to various typical matching methods in practical applications of filter materials made of composite covered yarns:

[0035] (1) For the dust removal filter material of the coal-fired boiler in the power plant, glass fiber is treated with PTFE as the reinforcement rib of the inner layer, and +PPS short fiber is used as the covering yarn.

[0036] (2) Dust removal filter material for waste incineration industry, made of glass fiber yarn or basalt yarn or blended yarn of glass fiber and metal wire or blended yarn of basalt fiber and metal wire or blended yarn of glass fiber and PTFE long fiber For reinforcing ribs, use PTFE or PPS or aramid staple fiber or blended fiber of P84 or above fiber as covering yarn.

[0037] (3) Dust removal filter material for cement industry, use glass fiber yarn or basalt yarn or metal wire or ...

Abstract

The invention relates to a composite covered yarn for a filtering material and a manufacturing method thereof. The composite covered yarn for the filtering material of the invention comprises an outer layer of covered yarn made of short fiber and an inner layer of reinforcing rib made of long fiber, wherein the composite covered yarn for the filtering material of the invention is formed by using the covered yarn, made of one or a plurality of types of short fibers, to cover the reinforcing rib or the metal wire reinforcing rib made of one or a plurality of types of long fibers by thermal cleaning, dipping, drying and sintering. The composite covered yarn for the filtering material manufactured by the method not only saves cost, but also combines the characteristics of high strength of the long fiber and good abrasion resistance and toughness of the short fiber and enhances service life, strength, high-temperature resistance and stability of the composite covered yarn.

Description

technical field [0001] The invention relates to a filter material and a manufacturing method thereof, in particular to a composite covering yarn for a filter material and a manufacturing method thereof. Background technique [0002] The tail gas of industrial fuels mostly contains a large amount of harmful substances, such as sulfides, nitrogen oxides, cyanides, etc. If they are discharged into the atmosphere, they will become a major source of air pollution. At present, the industrial dust removal filter materials on the market can be divided into three types: chemical fiber felt (cloth), glass fiber felt (cloth), and composite felt. These three types of filter materials have their own advantages and disadvantages. However, the existing filter materials have poor high temperature resistance and short service life. The price of raw materials for making filter materials varies greatly, ranging from a few thousand yuan per ton to more than three hundred yuan per ton, but eac...
