  • Patent number: 4086112
    Abstract: The invention provides a method of bonding and simultaneously printing a fabric, for example a non-woven web, by contacting the surface of the fabric with an ink comprising a dyestuff supported on a transfer sheet and subjecting discrete areas of the combination to heat and pressure. It is found in many cases that dye is strongly fixed, and that compared to conventional heat-transfer printing the method permits much shorter residence times and the possibility of using an extended range of dyestuffs.
