PPS fiber properties were tested on the previously developed abrasion tester, to which temperature-controlled attachment was added to build a testing system for fibers under high temperature, in order to work out the abrasion of textile filter materials under high temperature. The relation between abrasion and particle density was also studied. It shows that abrasion increases with the environmental temperature, especially when the temperature rises to a high degree. When the temperature and other conditions remain unchanged, abrasion changes with the particle density nearly as a index movement.
