A kind of non-woven non-woven filter bag processing method

Abstract

The invention discloses a treating method of a non-woven filter bag. The method includes the following steps that whether a target surface with a non-woven filter material needs to be treated or not is judged, and if yes, subsequent steps are executed; an air blowing port of an air blowing device is moved to the preset distance position right in front of the target surface; and air is supplied into an air inlet of the air blowing device according to preset air force, whether the target surface needs to continue to be treated or not is judged, and otherwise, air supplying stops. In this way, when it is determined that the target surface with the non-woven filter material needs to be treated, the position of the air blowing port is firstly controlled to reach the position suitable for air blowing, then air supplying is performed according to the preset air force, and therefore air blowing treatment can be well performed for the front side of the target surface with the non-woven filter material before solidifying of solid matter of a finishing process, adhesion of the solid matter to be solidified is achieved, hole gaps adhering to one another are restored, the breathability degree of the after-finishing process of filter material felt cloth is improved, and very high market application value is achieved.

Description

technical field [0001] The present invention relates to a filter material processing flow, in particular, to a non-woven non-woven filter bag processing method. Background technique [0002] Filter materials play an important role in daily production and life. The filtration of gases and liquids is involved in many industrial production and environmental protection devices. The core of the filter device is a filter medium such as a filter bag. The filter bag is a key part of the filtration process. The quality of the filter bag determines the filtration effect to a large extent. The filter bag material includes nylon, polypropylene, polyester (PET), stainless steel or polytetrafluoroethylene (PTFE). The filter bags are of various materials and complete specifications. Can be targeted to meet the application of various fields. The filter bag is called the heart of the filter, because the filter bag largely determines the filtering effect of the user. Textile materials as ...

Problems solved by technology

[0004] In order to improve the performance of the non-woven non-woven filter material felt, the existing technology often impregnates, covers or coats the non-woven non-woven filter material felt, but such treatments all have the risk of causing the air permeability of the felt to drop sharply. The common defects of the impregnation process, such as the impregnation process, the solids in the impregnation evaporate with the volatile liquid in the emulsion, which not only forms a protective film on the surface of the fiber to protect the fiber, but also seriously affects the adhesion of the pores between the filter felt cloth. Air flow or air permeability; another example is the coating process, the adhesive used not only adheres the PTFE membrane to the filter material, but also bonds a large number of original pores of the membrane and seriously affects its air permeability; another example is the coating process, regardless of Roller coating, scraping coating, and spraying all increase the surface filtration function and anti-chemical function on the front surface of the filter material, and its air permeability also drops significantly after direct drying and shaping
