摘要

A web release agent delivery system (E) for a heat and pressure fuser. The system includes an oil impregnated web (76,77,78) which is transported between supply and take-up rolls (80) while contacting the fuser roll (34). The web is formed of a material (95) having sub-denier fibers. It is preferred that the web is formed of a polyaramid fiber material (97,98) with a polyester binder (96) wherein some of the polyaramid fibers (98) are of a sub-denier thickness. The preferred composition of the material is approximately 70% polyester and 30% polyaramid with approximately 50% of the polyaramid fibers has a denier ranging between approximately 0.8 and 0.25 denier. The disclosed material has an improved oil retaining capacity and donor capacity as used in a web release agent delivery system for a heat and pressure fuser.
