Embodiment Construction
[0011] An organic-coated mixed fiber filter felt, including a base cloth, is characterized in that: the base cloth is compounded with mixed fibers composed of fine-denier viscose fiber and low-denier polypropylene fiber to make a mixed fiber felt body, and then an organic edge banding is used agent for edge sealing of the mixed fiber mat;
[0012] The composition ratio of the viscose fine-denier fiber and the high-strength low-denier polypropylene fiber is 4:6;
[0013] The organic edge sealing agent is made by dissolving resin glue A and B combination glue in organic solvent oil.
[0014] Further, the fine denier viscose fiber is a viscose fiber with a denier of 1.0-1.6 dpf.
[0015] Further, the low-denier polypropylene fiber is a polypropylene fiber with a denier of 3.0-3.6dpf.
[0016] Further, its production process is as follows: first dissolve the resin glue A and B combination glue in organic solvent oil, let it stand for 2-3 hours, wait for the organic solvent oil t...

Abstract
An organic coating mixed fiber filter felt includes a base fabric and is characterized in that the base fabric is composited with mixed fibers of fine-denier viscose fibers and low-denier polypropylene fibers to form a mixed fiber felt body, and then an organic edge sealing agent is used for edge sealing treatment of the mixed fiber felt body. The organic coating mixed fiber filter felt has the beneficial effects: 1, the base fabric is composited with the fine-denier viscose fibers and the low-denier polypropylene fibers, integration is performed by scientific formula proportion, and the filtering effect is improved; and 2, a pollution-free resin adhesive A and B combined adhesive is used for replacing a 601 preparation, and an organic solvent is used for replacing gasoline, so the sealingeffect is more ideal, and a phenomenon of edge leakage of a filter felt generated during use is effectively prevented; the technology greatly shortens the solvent evaporation time, and the product has the advantages of high compression strength, good filtering performance, strong acid and alkali resistance, labor reduction, easy operation, environmental protection and the like.
Description
technical field [0001] The invention relates to a filter felt, in particular to an organic-coated mixed fiber filter felt. Background technique [0002] As a filter material, filter felt is widely used in industrial dust collection, smoke control and other aspects. The traditional filter felt has the following defects, which are inconvenient for washing, poor sealing around, easy to leak, poor filtering effect, and short service life. It is more complicated than that, and needs volatile gasoline as a solvent to dissolve in use. In the actual operation process, gasoline needs 6-8 hours to completely volatilize, and the working environment is often polluted by high-concentration gasoline. Contents of the invention [0003] In order to solve the shortcomings of existing products, the invention provides an organic-coated mixed fiber filter felt with high compressive strength, good filtering performance and strong acid and alkali resistance. The present invention adopts the ...
