Abstract
Abstract A microporous metallised fabric suitable for use as a thermally-insulating material in a hostile environment comprises a microporous fabric substrate for example of a spun-bonded polyethylene having a layer of aluminium deposited thereon by a vacuum deposition technique. A thin layer - typically of 0.9-1.0 g/m<sup>2 -</sup> of a polyamide-based ink is then printed on to the metallising, by way of a photogravure printing process, in such a way as not to affect the porous structure of the metallised fabric.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
60 words
A microporous metallised fabric comprising a microporous flexible fabric substrate having a layer of metal deposited on at least one side thereof, which metallised fabric is characterised by the provision of a thin film of a polyamide-based ink printed on to the deposited metal at such a rate as not significantly to affect the microporous nature of the fabric substrate.
Claim 2
Dependent Claim
60 words
A microporous metallised fabric comprising a microporous flexible fabric substrate having a layer of metal deposited on at least one side thereof, which metallised fabric is characterised by the provision of a thin film of a polyamide-based ink printed on to the deposited metal at such a rate as not significantly to affect the microporous nature of the fabric substrate.
Claim 3
Dependent Claim
34 words
A microporous metallised fabric according to claim 1, further characterised in that the printed film of a polyamide-based ink has a thickness of the order of about one micron (1 x 10- 6 m).
Claim 4
Dependent Claim
50 words
A microporous metallised fabric according to any of the preceding claims, characterised in that the ink film is printed on the metallising by means of a photogravure printing process, depositing the ink at a rate of from 0.75 to 1.25g/m 2 but preferably from 0.9 to 1.0 g/m 2 .
Claim 5
Dependent Claim
30 words
A microporous metallised fabric according to any of the preceding claims, characterised in that the ink is printed on to the metallising within 48 hours of the metallising being completed.
Claim 6
Dependent Claim
47 words
A microporous metallised fabric according to any of the preceding claims, characterised in that the metallised layer comprises aluminium, deposited by a vacuum deposition technique on the fabric substrate, to have a thickness lying in the range of from 200 to 300 Å (20 to 30 nm).
Claim 7
Dependent Claim
30 words
A microporous metallised fabric according to any of the preceding claims, characterised in that the fabric substrate comprises a spun-bonded oelefin of a polyethylene resin and having a microporous structure.
Claim 8
Independent Claim
62 words
A method of manufacturing a microporous metallised fabric, including the step of metallising at least one surface of a microporous fabric, which method is characterised by the further step of printing on the metallised surface a thin film of a polyamide-based ink at such a rate that the microporous structure of the metallised fabric is not significantly affected by the ink film.
Claim 9
Independent Claim
62 words
A method of manufacturing a microporous metallised fabric, including the step of metallising at least one surface of a microporous fabric, which method is characterised by the further step of printing on the metallised surface a thin film of a polyamide-based ink at such a rate that the microporous structure of the metallised fabric is not significantly affected by the ink film.
Claim 10
Dependent Claim
43 words
A method according to claim 7, further characterised in that the printing step is performed by a photogravure printing process, depositing the polyamide-based ink at a rate of from 0.75 to 1.25 g/m 2 but preferably from 0.9 to 1.0 g/m 2 .
Claim 11
Dependent Claim
24 words
A method according to claim 8, characterised in that the printing is performed not more than 48 hours after the metallising has been completed.
