Fabrication method of antistatic dedusting filter cloth

Abstract

The invention relates to a fabrication method of antistatic dedusting filter cloth. The fabrication method comprises the following steps: 1. treating acrylic fiber with a copper salt to form modified acrylic fiber treated by the copper salt; 2. mixing the modified acrylic fiber with polyester staple fiber to form mixed fiber; 3. making a textile assistant; 4. spraying the textile assistant into the mixed fiber before the mixed fiber is opened and enters a hopper; and 5. transferring the mixed fiber with the textile assistant into the hopper to be made into the dedusting filter cloth according to basic production procedures of non-woven fabric. In the fabrication method, firstly the modified acrylic fiber treated by the copper salt is mixed with the polyester staple fiber, then the textile assistant composed of an antioxidant and a stabilizer is sprayed, and finally the dedusting filter cloth is made. The fabrication method has the advantages that the modified acrylic fiber is integrally mixed with the polyester staple fiber, and the textile assistant is sprayed into the mixed fiber, thus avoiding volatilization of the copper salt in the dedusting filter cloth, reaching good antistatic effect of the dedusting filter cloth and ensuring safety production.

Description

technical field [0001] The invention relates to a method for manufacturing a dust-removing filter cloth, in particular to a method for manufacturing an antistatic dust-removing filter cloth. Background technique [0002] At present, antistatic textiles usually use copper salt-treated modified acrylic fiber yarns with conductive properties embedded in the mesh cloth at a certain interval with a distance of less than 3.5 cm. The textile has an antistatic effect due to the embedding of modacrylic fibers treated with copper salts. However, during the long-term storage or weaving process of this textile, the conductive component copper salt in the fiber component is easily volatilized because it is directly exposed to the air, so that the conductivity of the textile is significantly reduced, and the antistatic effect is not ideal. Therefore, using this process to produce, the modified acrylic fibers treated with copper salts are embedded in the fibers of the non-woven dust filte...

Problems solved by technology

However, during the long-term storage or weaving process of this textile, the conductive component copper salt in the fiber component is easily volatilized because it is directly exposed to the air, so that the conductivity of the textile is significantly reduced, and the antistatic effect is not ideal.

Therefore, using this process to produce, the modified acrylic fibers treated with copper salts are embedded in the fibers of the non-woven dust filter cloth. Due to long-term exposure to the air, the antistatic performance of the dust filter cloth is also significantly reduced, and the antistatic effect is not good. not ideal

Especially in the occasions where anti-static dust filter cloth is required, an explosion will occur because the static electricity accumulated on the surface of the dust filter cloth cannot be dredged immediately.
