A dictionary entry on bleaching textiles from Knight's American Mechanical Dictionary. It traces the history from ancient exposure bleaching and the Dutch 'Hollands' linen, through bucking and crofting, sulphuric acid, chlorine and bleaching powder. It then describes the nineteenth-century factory process for cotton (singeing, dash-wheels, bucking, chemicking, souring) and briefly covers linen, wool, silk and straw. An engraving shows dash-wheels in operation.
