Abstract
A microporous metallized 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 aluminum deposited thereon by a vacuum deposition technique. A thin layer--typically of 0.9-1.0 g/m.sup.2 --of a polyamide-based ink is then printed on to the metallizing, by way of a photogravure printing process, in such a way as not to affect the porous structure of the metallized fabric. The metallized fabric of this invention finds a particular application as screening for commercial glass-houses, to reduce the heat-losses therefrom.
Claims10
A microporous metallised fabric comprising a microporous flexible fabric substrate having a layer of metal deposited on at least one side thereof, and 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.
A microporous metallised fabric comprising a fabric substrate of a spun-bonded polyethylene resin and having a microporous structure, a layer of aluminum metallising deposited on one surfce of the fabric substrate with a thickness of from 200 to 300 .ANG., and a thin film of a polyamide-based ink printed on to the aluminum metallising by a photogravure printing process to have a film thickness of about one micron (1.times.10.sup.-6 m).
A method of manufacturing a microporous metallised fabric, including a first step of metallising at least one surface of a microporous fabric substrate and a second 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.
