Embodiment Construction

[0033] Choose different combinations according to the performance of various fibers to meet the needs of various industries or working conditions. According to a variety of typical matching methods in practical applications of filter materials made of composite covered yarn:

[0034] (1) The dust removal filter material of coal-fired boiler in power plant is made of glass fiber treated with PTFE as the inner reinforcing rib, and +PPS short fiber is used as the covering yarn.

[0035] (2) The dust removal filter material used in the garbage incineration industry is made of glass fiber yarn or basalt yarn or a blended yarn of glass fiber and metal wire or a blended yarn of basalt fiber and metal wire or a blended yarn of glass fiber and PTFE long fiber. The reinforcing ribs are covered with PTFE or PPS or aramid staple fibers or blended fibers of P84 or above fibers.

[0036] (3) Dust removal filter material used in cement industry, glass fiber yarn or basalt yarn or metal wire or the...

Abstract

The invention relates to a composite covered yarn and a manufacturing method thereof and also relates to a high-temperature filter cloth. The composite covered yarn comprises an outer layer of coveredyarn made of short fiber and an inner layer of reinforcing rib made of long fiber, wherein the composite covered yarn is formed by using the covered yarn, made of one or a plurality of types of shortfibers, 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 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. The composite covered yarn can be made into the filter cloth.

Description

Technical field [0001] The invention relates to a composite fiber and a manufacturing method thereof and a filter cloth made of the composite fiber, in particular to a composite covering yarn and a manufacturing method thereof, and a filter cloth made of the composite covering yarn. Background technique [0002] Most of the exhaust gas of industrial fuels contains a large amount of harmful substances, such as sulfide, nitrogen oxide, cyanide, etc., if it is discharged into the atmosphere, it will become a major source of air pollution. At present, the industrial dust filter materials on the market can be divided into three types: chemical fiber felt (cloth), glass fiber felt (cloth), and composite felt. Each of these three types of filter materials has advantages and disadvantages. However, the existing filter material has poor high temperature resistance and short life. The price of raw materials for making filter materials varies greatly, ranging from a few thousand yuan per t...
