ABSTRACT:
By using printing pastes containing thiourea dioxide together with finely dispersed calcium, magnesium or zinc hydroxide, present in the paste as such or generated from components in the printing paste during a treatment process, fabric discharge printing processes may be developed which have the advantage of decorating fabric webs, garments or garment panels effectively, even in dry heat conditions, whilst avoiding contamination of such fabrics with undesirable residues, particularly formaldehyde.
