Abstract
The invention relates to an apertured camouflage material where the apertures are made as arcuate slits so that tongues are formed (FIGS. 4A, 4B). The material is a laminate of a supporting layer to which is applied a plastics layer which is initially under internal tensional stress, the tongues curling outwards when the internal stresses are activated by the slitting and heat (see FIG. 4B) thus forming a three-dimensional camouflage sheet. The pre-stressed material is blown low density polyethylene film.

Camouflage material in the form of a three-dimensional camouflage-coloured apertured sheet, characterized in that there is included in the sheet a supporting layer on which there is laminated a layer of a plastics material initially having internal tensional stresses, said sheet having variously oriented, unconnected, curved slits going through the sheet, the slits forming apertures in said sheet and forming tongues which, due to the action of the internal tensional stresses in said plastics material that are activated when said sheet is slitted, are curled outwards from the general plane of the sheet away from the supporting layer to which said plastics material is secured.
The method of making a three-dimensional camouflage sheet which comprises the steps of providing blown low density polyethylene film having latent internal tensional stresses therein, laminating said film to a supporting textile web, cutting the laminate in spaced apart incomplete generally circular slits to form spaced apart tongues of the sheet material and to activate the latent tensional stresses to cause said tongues to curl upwardly.
