Current paper technology developments in the dryer section are therefore concentrated on accomplishing more effective energy saving drying techniques. This has necessitated improved heat transmission and ventilation effectiveness in order to avoid lengthening the dryer section. Web stability has been improved by eliminating or decreasing open draws and by utilizing more advanced web stabilizing equipment. In this context the polyester dryer fabric plays an important role.

As an integral part of the papermaking process, the polyester dryer fabric is designed to give maximum web support and to minimize any uncontrolled air fluctuations that could cause run ability disturbances. Each polyester dryer fabric is specified to be compatible with machine geometry and ventilation equipment in the machine, for optimal heat and mass transfer. The polyester dryer fabric influences the drying process and machine run ability by nature of its openness, structure, and chemical surface properties. Recent developments have made the fabric an influential tool with which we can influence, and in many cases, even control the drying process. This paper discusses the latest innovations in the field of polyester dryer fabrics, making it possible to control the web at even higher speeds, control CD shrinkage, and minimize contamination.

As paper machine speeds increase, the requirement for total run ability control in the dryer section becomes of paramount importance. Modern production requirements face us with the ever-increasing challenge of drying paper with minimal energy use in the shortest time.
