Dryer fabric with small ventilation is adapt for the first platoon of the dryer, due to the fresh sheets from pressing sector are in high moisture and low strength to be marking sensitive.
The medium ring of spiral dryer fabric should be used in the middle dryers, and for the latter dryer cylinders, big loop dryer fabrics should be applied, because the sheets became dryer and greater permeability is required.
For the bag paper, paper board and other heavy-duty paper sheets which need high evaporation during the drying process, spiral fabrics could be deployed in the entire drying sector thanks to its greater permeability. If a qualified smooth surface is required, the woven dryer fabrics should be assembled at the first platoon of the dryer, and spiral fabrics used in the following drying cylinders.
Dryer fabrics with improper air permeability will be counterproductive, too small ventilation will make the sheets moisture uneven in lateral, and too big will cause sheets to shock on the belt, and much more steam will condense and drop on the sheet when meeting lower outer temperature.
