The main function of a polyester dryer fabric is to ensure even and efficient drying. Polyester dryer fabric influences the drying process by its openness and contact with the paper.

                                       

The photos show an example of polyester dryer fabric on the paper machine, a close-up of two dryer fabrics, one with a fine yarn (bottom) and one with a coarser yarn (top) finally a pocket ventilation unit between the two drying cylinders. Fabric selection at each dryer position uses a balance of fabric properties to yield maximum life at optimum production rates while maintaining runnability, without adversely influencing the quality of paper being manufactured.

Maintaining paper quality during the drying process requires undisturbed web to fabric contact and non-marking surface   and seam structures. Depending upon the machine conditions, polyester dryer fabric life should be about 6 to18   months.  Choice of fabric material has a strong impact on life. Improved cleaning techniques including the use of chemicals, has  prolonged the life of fabrics. The most common material used in fabric manufacture is heat stabilised polyester (PET).  Other synthetic materials are also used dependant on the conditions found within the dryer section. Materials behave  differently at different humidity and temperatures.
