Abstract
The present invention provides a permeable filtering felt made from aromatic polyamide and a making technique thereof. The permeable filtering felt has the material components of 37.225% of 190 g of aromatic polyamide fiber at an upper layer, 25.49% of 130 g of aromatic polyamide fiber base cloth at the middle, and 37.225% of 190 g of aromatic polyamide fiber at a lower layer. The technique has the steps of bale breaking, opening, cotton feeding, carding, mesh placement, pre-thrusting, main thrusting 1, main thrusting 2, main trusting 3, surface decoration, edge cutting, roll winding and post-treatment. The permeable filtering felt of the present invention has the advantages of high temperature resistance, chemical corrosion resistance, high filtering load resistance, good mechanical performance, high air permeability and good dust removing effect.
