In preparation for the dyeing process, fabrics are first treated in a scouring process to remove dirt and impurities. Chemicals and dyes are then added onto the scoured fabric for the dyeing or bleaching process. The duration of the bleaching and dyeing processes depends on the color shade and the raw materials being used. Dyed fabrics are then inspected by the quality assurance staff. Fabric that does not require printing will then be processed through the finishing step.
