TREATING TEXTILE MATERIALS USING LIQUIDS, GASES OR VAPOURS

Description

D06B covers processes and apparatus for treating textiles through contact with liquids, gases, or vapours, including washing, bleaching, dyeing, and chemical finishing operations. This subclass encompasses wet processing methods such as immersion, spraying, and circulation treatment, as well as gaseous treatments like steaming and fumigation. The classification includes machinery for applying treatment media, controlling treatment conditions, and removing excess liquids or gases from textile materials. Related finishing operations involving mechanical deformation (pressing, calendering) are classified elsewhere in D06.
