Abstract
A drapeable decorative sheet material having a natural mossy-looking appearance has a flexible film substrate, a coating of a flexible adhesive bonded onto the film substrate, and fragments of sphagnum moss adhering to and substantially covering the adhesive layer. The fragments comprise relatively large fibrous moss fragments upstanding from the adhesive layer and having spacings between them, and relatively smaller particulate moss fragments distributed on the adhesive layer between the relatively large fragments.
Claims17
Drapeable decorative sheet material comprising a flexible film, a flexible adhesive layer bonded to the film, and fragments of sphagnum moss adhering to and substantially covering said adhesive layer, said fragments comprising relatively large fibrous fragments of the moss upstanding from the adhesive layer and having spacings between them, and relatively smaller particulate fragments of the moss distributed on the adhesive layer between the relatively large fragments.
Method of making drapeable decorative sheet material comprising impregnating sphagnum moss with dyeing and humectant agents in aqueous solution, drying the dyed and impregnated moss, subjecting the dried moss to size reduction, screening the fragments to obtain a particulate fraction passing through about 1 to about 2.5 mm square mesh openings and screening the oversize fragments to obtain a fibrous fraction passing through about 4 to about 10 mm square mesh openings, coating a water-based pressure sensitive resin emulsion on a plastic film to form a tacky pressure-sensitive layer thereon, applying to the pressure sensitive layer firstly said fibrous fraction of size-reduced moss fragments and secondly said particulate fraction of size-reduced moss fragments, to substantially completely cover the pressure-sensitive layer with said moss fragments adhering to the surface of said layer, and drying the moss-covered sheeting thus obtained.
