Abstract

A sheet material, for use for example in a screen, windbreak or deck-chair, comprises a fabric having applied to at least one face thereof a coating or layer of a material reflective to radiation at least in the ultra-violet wavelength range and preferably in the infra-red wavelength range also. The fabric may be a woven polypropylene or polyethylene film to which is bonded a metallised polyester or polypropylene film, and an intermediate foam layer may be provided. Bonding may be effected by calendering after flame bonding or infra-red heating by hot calendering.

Description

SPECIFICATION Reflective material This invention relates to reflective material and in particular to material which is reflective to radiation of the ultra-violet wavelengths at least. Such a material may be used as a reflective screen for outdoor use, being particularly suitable for use as windbreaks or outdoor furniture.
The invention provides a sheet material comprising a fabric provided at one surface thereof with a coating or layer of a material which is reflective to radiation at least within the ultra-violet wavelength range.
The coating or layer may comprise a material which in addition is reflective to radiation within the infra-red wavelength range. In either case the sheet material may be used in the construction of outdoor furniture whereby the user of such furniture may develop a more even sun-tan due to the reflection of the solar ultra-violet radiation, but in the latter case also feels warmer due to solar heat radiation being reflected onto his body.
The coating or layer may comprise a metallic coating which may be in the form of a coating of metallic particles applied in the form of a spray to the fabric, a layer of metallic foil bonded to the fabric, or a metallised film of a thermoplastics material bonded to the fabric. An intermediate sheet of a foam material may be provided between the coating or layer and the fabric if desired.
In the case of a reflective layer, such layer and the fabric, or the layer, intermediate foam sheet and the fabric, may be bonded together by flame bonding, by hot callendering, by infra-red heating, the latter with or without an adhesive, or by an adhesive alone.
The fabric may comprise a woven, plain or extruded thermoplastics material, for example polypropylene or polyethylene. The metallised film may be polyester, polyethylene or polypropylene, which may be lacquered, and the adhesive when used may be polyester, polyethylene or polypropylene film. When an intermediate sheet of foam is used such sheet may be polyester or polyether foam.
The sheet material of the invention may be incorporated into an article of furniture, which may be adapted for outdoor use. Such article of furniture may comprise a screen for use in reflecting solar radiation, for example on a beach, and such screen may be adapted for use as a windbreak. Alternatively the furniture may comprise a deck-chair.
The fabric may be of any suitable material such as canvas. However, the abovementioned plastids materials are preferred since they are weather resistant without the need for any post treatment.
For certain applications both sides of the fabric may have a reflective coating or layer applied thereto in accordance with the invention.
Preferred embodiments of the invention will now be further described by means of the following examples.
Example 1 A metallised polyester film which'has been lacquered is bonded to an intermediate polyester foam sheet 1.5 mm thick and to a woven polypropylene film. These materials are bonded by passing the foam sheet over gas jet flames so that the foam becomes tacky and then passing the three materials through a roller nip. The roller nip applies a pressure to the laminate thus formed so as to bond the metallised film and the woven material to the tacky foam sheet which is reduced in thickness by this process from 1 .5mm to 0.5mm.
Example 2.
A metallised polypropylene film is bonded to a woven polypropylene fabric by passing the two materials between heated calender rollers at a pressure of between 1.5 and 4.5 Kgm/sq.mm.
Example 3 The materials of example 2 are heated by means of infra-red heaters before being passed between calender rollers. The pressure applied by the rollers is as in example 2 and the rollers may or may not be heated dependent upon the amount of heating provided by the infra-red heaters.
Example 4 A metallised polypropylene film is bonded to a woven polypropylene film by means of a polyethylene film which is used as an adhesive. In this case the polyethylene film is heated by infra-red heaters and then fed with and between the other two materials into the nip of calender rollers. The heated polyethylene film becomes tacky so that a bond is formed between the materials in the nip.
In any of the above examples the reflective layer may be chosen from polyester or polypropylene film, which may be lacquered if desired and the fabric may be woven polypropylene or polyethylene film. In example 4the adhesive may be polypropylene film.
As alternatives to the above examples a metallic coating may be applied, for example by electrostatic spraying, to the fabric, or a metal foil may be applied, for example by means of an adhesive and/or by means of pressure, to the fabric. In the latter case the metal foil and the fabric may be passed between flexible, for example rubber, rollers so that the foil is caused to adhere between the interstices of the fabric.

2. A sheet material according to claim 1 wherein said coating or layer is reflective to radiation within the infra-red wavelength range.
3. A sheet material according to claim 1 or claim 2 wherein said coating or layer comprises a metallised film of a thermoplastics material.
