ABSTRACT:
A polyester monofilament is formed from a high temperature polyester resin, a PET resin and a hydrolyric stabilizing agent, and exhibits increased resistance to hydrolytic and thermal degradation. The high temperature polyester resin can be blended with from 0 to about 5 percent by weight of a thermal stabilizing agent. In addition, a masterbatch including the PET resin and hydrolytic stabilizing agent may be compounded prior to blending with the high temperature polyester resin. A fabric may be produced having increased resistance to hydrolytic and thermal degradation and includes a plurality of woven polyester monofilaments, comprising a high temperature polyester resin, a PET resin and a hydrolytic stabilizing agent. Such fabrics have utility as fabrics for the dryer sections of paper making machines.
