The Denim fabric is carrying a lot of chemicals because of its manufacturing process. Also, the Denim is a rush, hard and heavy fabric. So the felt has to be resistant against chemicals and abrasion. So the Aramid felts have this advantage to be resistant against chemicals and abrasion. Using an Aramid felt will elongate the working life of the felt by around three times with an optimum result.
