Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
72 words
A method of simultaneously dyeing and bonding a fabric comprising thermoplastic fibres, wherein a transfer sheet supporting an ink comprising a heat transferable dyestuff is contacted with said fabric, and the sheet and fabric are subjected to heat and pressure in spaced discrete areas such that the fabric becomes thermally bonded and the dyestuff is transferred from the transfer sheet to the fabric at least in areas corresponding to said discrete areas.
Claim 2
Independent Claim
72 words
A method of simultaneously dyeing and bonding a fabric comprising thermoplastic fibres, wherein a transfer sheet supporting an ink comprising a heat transferable dyestuff is contacted with said fabric, and the sheet and fabric are subjected to heat and pressure in spaced discrete areas such that the fabric becomes thermally bonded and the dyestuff is transferred from the transfer sheet to the fabric at least in areas corresponding to said discrete areas.
Claim 3
Dependent Claim
14 words
A method according to claim 1 wherein said fabric is a non-woven fibrous web.
Claim 4
Dependent Claim
20 words
A method according to claim 1 wherein said fabric is subjected to heat and pressure for less than 1 second.
Claim 5
Dependent Claim
19 words
A method according to claim 1 wherein the transfer sheet is preheated before being contacted with the said fabric.
Claim 6
Dependent Claim
33 words
A method according to claim 1 wherein the thermoplastic fibres are formed from a polyamide, the dyed and bonded fabric being further subjected to a steam treatment followed by a hot water wash.
Claim 7
Dependent Claim
42 words
A method according to claim 1 wherein heat and pressure are supplied in a nip between an ultrasonically energized horn and an anvil provided with a surface pattern of raised lands, the transfer sheet being positioned between the fabric and the anvil.
Claim 8
Independent Claim
91 words
A method of printing and bonding a fabric of thermoplastic fibers comprising contacting the surface of the fabric with a transverse sheet which supports an ink comprising a heat transferable dyestuff, and subjecting said sheet and fabric to heat and pressure in spaced discrete areas, the combination of said heat and pressure being effective to cause simultaneous (1) thermal bonding of said fabric in said spaced discrete areas and (2) transfer of the dyestuff from said transfer sheet to the fabric at least in areas corresponding to said spaced discrete areas.
Claim 9
Independent Claim
91 words
A method of printing and bonding a fabric of thermoplastic fibers comprising contacting the surface of the fabric with a transverse sheet which supports an ink comprising a heat transferable dyestuff, and subjecting said sheet and fabric to heat and pressure in spaced discrete areas, the combination of said heat and pressure being effective to cause simultaneous (1) thermal bonding of said fabric in said spaced discrete areas and (2) transfer of the dyestuff from said transfer sheet to the fabric at least in areas corresponding to said spaced discrete areas.
