Abstract
Abstract This invention relates broadly to the simultaneous heat transfer printing or transfer dyeing and embossing or surface texturing of fabrics or other relatively flat materials containing thermoplastic fibers or other thermoplastic components or finishes. More particularly, the invention provides a process for such simultaneous printing and embossing or surface texturing in which the heat transfer pattern printed or otherwise deposited in sublimable or vaporizable dye on a printing-embossing sheet can be transferred to one or several materials without being substantially affected by the embossing. The invention also provides an embossing means for use in that process; and an apparatus to implement it.

Claims Analysis
Total Claims: 30
Claim 1
Independent Claim
202 words
A method of printing in colour onto a thermoplastic fabric a replica of a first pattern and of simultaneously embossing in relief into that fabric a second pattern without substantially affecting the first pattern as so printed, said method comprising the steps of (a) superposing i. a heat transfer printing means bearing a vapourizable or sublimable dye according to said first pattern, the dye having a high affinity for said thermoplastic fabric; ii. an embossing sheet or web, the material of which is permeable to said dye but has practically no affinity or retention properties for said dye, said embossing means having in both faces or at least in the face thereof remote from the transfer printing means, a design in relief according to said second pattern, said relief being created by alternation of raised and hollow portions and/or by apertures in the embossing surface, and iii. a thermoplastic fabric; (b) applying heat and pressure to the superposed members to cause the transfer by migration of the dye through the material of the embossing means and into the thermoplastic fabric and also to cause reproduction in the latter, in relief, of said second pattern, and (c) separating said members one from another.
Claim 2
Independent Claim
202 words
A method of printing in colour onto a thermoplastic fabric a replica of a first pattern and of simultaneously embossing in relief into that fabric a second pattern without substantially affecting the first pattern as so printed, said method comprising the steps of (a) superposing i. a heat transfer printing means bearing a vapourizable or sublimable dye according to said first pattern, the dye having a high affinity for said thermoplastic fabric; ii. an embossing sheet or web, the material of which is permeable to said dye but has practically no affinity or retention properties for said dye, said embossing means having in both faces or at least in the face thereof remote from the transfer printing means, a design in relief according to said second pattern, said relief being created by alternation of raised and hollow portions and/or by apertures in the embossing surface, and iii. a thermoplastic fabric; (b) applying heat and pressure to the superposed members to cause the transfer by migration of the dye through the material of the embossing means and into the thermoplastic fabric and also to cause reproduction in the latter, in relief, of said second pattern, and (c) separating said members one from another.
Claim 3
Dependent Claim
37 words

Claim 4
Dependent Claim
27 words
A method as claimed in claim 1, wherein the thermoplasticity of the fabric to be printed is due, at least partially, to a thermoplastic finish or coating.
Claim 5
Dependent Claim
36 words

27 words
A method as claimed in claim 1, including the preliminary step of providing the embossing sheet or web with a dye trap according to a third pattern.
Claim 7
Dependent Claim
21 words
A method as claimed in claim 1, wherein said transfer printing means and said embossing sheet or web are bonded together.
Claim 8
Dependent Claim
39 words
A method as claimed in claim 1, wherein the embossing sheet or web contains a vapourizable or sublimable dye which also migrates into the thermoplastic fabric during the transfer printing operation, adding to it a supplementary colour and/or pattern.
Claim 9
Dependent Claim
33 words
A method as claimed in claim 7, wherein the embossing means contains, instead of or supplementary to the dye, a finishing product which is transferred onto the thermoplastic material during the heat transfer.
Claim 10
Dependent Claim
87 words
A method as claimed in claim 1, wherein the transfer printing means bears sublimable or vapourizable dyes of different colours or shades and of different penetration strength, side by side, or in a blend, and wherein the embossing sheet or web has portions letting through all colours while other portions let through only the high penetration dyes or none of the dyes, whereby the colours and designs obtained on the simultaneously embossed thermoplastic fabric are different and more diversified than those of the original transfer printing means.
Claim 11
Dependent Claim
72 words
A method as claimed in claim 9 wherein the once used transfer printing means is not exhausted at portions where it faced areas of the embossing means, which were impeding the migration of some of the dyes, and wherein it is reused for a second printing, and--if used without an embossing means--will transfer onto a second thermoplastic material the negative, somewhat lighter, image of the coloured pattern produced by the first transfer.
Claim 12
Dependent Claim
22 words
A method as claimed in claim 1, wherein said transfer printing means and said embossing sheet or web comprise a single element.
Claim 13
Dependent Claim
33 words
A method as claimed in claim 11, wherein the single element printing-embossing means has a pattern in relief in opposed faces and prints and embosses two fabrics at once, one with each face.
Claim 14
Dependent Claim
55 words
A method as claimed in claim 11, performed repetitively, wherein the single element printing-embossing means is made of an absorbent material and contains a sufficient quantity of dye to repeat the printing-embossing operation several times without the need to add new dyestuff and with practically no variance of the shade obtained from print to print.

Claim 18
Dependent Claim
33 words
A method as claimed in claim 11, wherein the dye is deposited on one face only of the single element printing-embossing means, while the colour transfer can still take place through both faces.
