The requirement for total runnability control in the dryer section becomes of paramount importance as paper machine speeds increase . Modern production requirements of polyester dryer fabric face us with the ever-increasing challenge of drying paper with minimal energy use in the shortest time.

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

The polyester dryer fabric is designed to give maximum web support and to minimise any uncontrolled air fluctuations that could cause runnability disturbances as an integral part of the paper making process . Each 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 have an influences on the drying process and machine runnability 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.
