Fabric thermal treatment process - using jets to deliver heating medium to warm fabric surface by convection

摘要

A process and equipment are claimed for applying a thermal treatment to moving fabrics by subjecting them to streams of hot air or steam. The fabrics passing through the process one can be woven, knitted or non-wovens. In the process zone the fabric passes through a series of sections where the heat is applied by the heated streams by convection on to the fabric surface, the movement of the fabric giving an alternating heat application. The process gives an increased heating capacity when drying or fixing the fabric, without requiring any support or suction drum to hold the matl. in place.
