AI Technical Summary
Existing coated polyester filter cloths have poor abrasion resistance under complex working conditions and are easily torn by dust, leading to rapid filter bag failure and inability to meet strict environmental emission standards.
The fabric consists of a polyester base layer, a wear-resistant nonwoven layer, and a breathable hot melt adhesive mesh layer, which are laminated from the inside out. A polytetrafluoroethylene microporous membrane layer is then laminated on top. The integrated felt structure is formed by needle punching and hot pressing at low temperature. Combined with micro-fire singeing and low-temperature plasma treatment, the bonding strength of the fiber surface is enhanced.
It improves the abrasion resistance and filtration efficiency of the filter cloth, extends its service life, prevents membrane delamination and tearing, and maintains good air permeability and filtration accuracy.
