Improvements in fabric printing |
(57) 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.
