Problems solved by technology

[0003] High filtration precision filter cloth generally includes a dust-receiving layer, an inner filter layer, a base cloth layer and an outer filter layer. The overall filtration accuracy of the filter cloth mainly depends on the filtration accuracy of the dust-receiving layer. The membrane is formed by hot pressing; but such a processing technology needs to expand the filter cloth and the filter membrane to be processed at the same time, and ensure the alignment of the two, and there is a problem that the processing is inconvenient and affects the production efficiency; therefore, a new solution needs to be proposed to solve the problem. this problem

Embodiment Construction

[0027] The present invention will be described in further detail below.

[0028] The production process of filter cloth with high filtration precision includes the following steps:

[0029] Weaving part

[0030] (1) Fiber opening: The fibers are first broken up by the bale opener, and distributed to the coarse opener for opening by automatic weighing according to the ratio of the production process, and the opened fiber is sent to the bulk by the fan of the opener. The cotton is mixed evenly in the warehouse and then transported to the fine opener for re-opening;

[0031] (2) Carding: The opened fibers are transported to the air pressure cotton box feeding machine through the cotton storage box fan and sent to the carding machine for carding and web forming to the web laying machine;

[0032] (3) Laying: the carded cotton web is transported into the web laminating machine through the carbon curtain, and the cotton web is folded by the web laminating machine and sent to pre-a...

Abstract

The invention discloses a production technology for a high-filtering-precision filter cloth, and relates to a filter cloth. The aim is to solve the problem that a dust-ward layer is formed with difficulty. In the technical scheme, the production technology for the high-filtering-precision filter cloth is characterized by including fiber opening, carding, net laying, needling, calendaring and singeing, dipping and air blowing, forming of the dust-ward layer and sizing. According to the production technology for the high-filtering-precision filter cloth, the filtering precision of the dust-wardlayer is more uniform, filtering efficiency is higher, the connecting strength of the dust-ward layer and an inner filtering layer is higher, the production efficiency of the filter cloth is higher, and production costs are lower.

Description

technical field [0001] The invention relates to a filter cloth, more specifically, it relates to a production process of a filter cloth with high filtering precision. Background technique [0002] Filter cloth is a filter medium made of natural fibers or synthetic fibers, mainly used in air filtration and dust removal, dust collection powder, to purify the air, protect the environment, in smelters, chemical plants, sugar, dyes, medicine, food and other industries. [0003] High filtration precision filter cloth generally includes a dust-receiving layer, an inner filter layer, a base cloth layer and an outer filter layer. The overall filtration accuracy of the filter cloth mainly depends on the filtration accuracy of the dust-receiving layer. The membrane is formed by hot pressing; but such a processing technology needs to expand the filter cloth and the filter membrane to be processed at the same time, and ensure the alignment of the two, and there is a problem that the pro...
