Abstract
The present invention is a kind of production method of aramid fiber filter cloth, by adding the colloidal substance that can be heated at a certain temperature during aramid fiber spinning, obtain modification of aramid fiber, filter cloth is prepared using modification of aramid fiber, so that filter cloth is influenced by temperature at work, pin hole can be blocked by colloid substance a small amount of in aramid fiber, to improve the efficiency of filtering, and simple process, it is easy to operate.
Description
Technical field
The present invention relates to technical field of textile chemical engineering, and in particular to a kind of production method of aramid fiber filter cloth.
Background technique
Environmental pollution is got worse at present, and government, which has the discharge of industrial waste gas etc., to be distinctly claimed, therefore, filter cloth filter bag
Use it is also more and more extensive.And in order to reach maximum discharge requirement, the manufacture of filter cloth filter bag requires to be consequently increased.
The main material of filter cloth filter bag has aramid fiber, PPS etc., and wherein aramid fiber is with its excellent high temperature resistant, corrosion-resistant
Etc. performance applications it is relatively broad.
The manufacturing process of filter cloth filter bag is generally required by sewing, and will appear some pin holes during sewing, can shadow
The efficiency and quality of filtering are rung, therefore, technical staff has developed a variety of methods to block pin hole:As used people in the follow-up process
The mode of work silica gel closure pin hole;For another example by sewing thread by the way of hot melt adhesive coating etc..
However, above method has the problems such as complex procedures, therefore, improves one kind and fast and efficiently prepare filter cloth
Method, while can effectively prevent the generation of pin hole is when a difficult problem of the forward swing in face of filter cloth filter bag technical staff.
Summary of the invention
In view of the above shortcomings of the prior art, the present invention provides a kind of production method of new filter cloth.To realize above-mentioned mesh
, technical scheme is as follows:
A kind of production method of aramid fiber filter cloth, steps are as follows:
1. a kind of production method of aramid fiber filter cloth, steps are as follows:
(1) preparation of modification of aramid fiber:Colloidal substance is added in aramid fiber spinning solution, the additive amount of colloidal substance is to spin
The 1.2-1.9% of silk liquid, spinning solution are stretched in air gap after spinneret button extrusion with gear pump, and total stretching ratio is 5.6, then
It by coagulating bath solidification, washing, neutralizes, dry, obtains modification of aramid fiber;
(2) yarn is respectively prepared in modification of aramid fiber and common aramid fiber;
(3) preparation of filter cloth:Common aramid fiber and modification of aramid fiber are prepared into filter cloth together, wherein modifying aramid fiber
The yarn of fiber preparation is only arranged in the position sewed, and modification of aramid fiber yarn is continuously arranged at sewing position
Radical is 10-20 root.
In the preferred scheme, spinning speed 240m/min.
Colloidal substance is to melt to form gelatinous thermosol during applied at elevated temperature, blocks pin hole.
Beneficial effects of the present invention:Modification of aramid fiber is obtained by adding colloidal substance in aramid fiber spinning solution, so that
Preparing filter cloth filter bag during subsequent applied at elevated temperature by modification of aramid fiber, colloidal substance melting in fiber can
The pin hole generated because of sewing is blocked, wherein there are following several respects to pay attention to:One, the additive amount of colloidal substance should guarantee to make
By thermal energy plugging pin hole, also to guarantee that it cannot influence the performance of spinning solution such as viscosity etc. in the process, influence its spinnability;
Two, only the use of modification of aramid fiber is reduced, guarantees filter cloth in the aramid fiber yarn for the position setting modification for needing to sew
Main performance;Three, modification of aramid fiber yarn is in the continuously arranged radical in sewing position and colloidal substance in modification of aramid fiber
In content it is closely related, be that have passed through a large amount of experiment, guarantee completely block pin hole.This method simple process, without subsequent
Artificial closure, reduce labour, solve a great problem in current filter cloth strainer field.
