==Vacuum suction==

Another technique that has been tested is ''vacuum suction''. The excess liquid is sucked through a column from the fabric after dipping. Uneven woven edges can cause problems and with the edge not properly sealed the vacuum varied and dewatering was uneven. Increasing in usage of the technique has been substantial since the problems with edge seal has been solved by using a flexible tube. The equipment works best on normal fabrics that are not too sparse and that can improve dewatering significantly.

* '''At pre-treatments''': The equipment delivers an effective output of the various washing and rinsing liquids including an efficient dewatering.
