ABSTRACT:
A method of producing a wall or ceiling covering that is dry-stripable from the wall, is flexible and has good opacity, and will fully retain an embossed pattern even when the sheet is soaked with a water based adhesive. A sheet is provided containing 10 to 90% by weight of cellulose pulp fibres and 10 to 90% by weight of discontinuous fibres of two different synthetic thermoplastic polymeric materials. Staple fibres may also be added. The sheet is then heated to a temperature intermediate the temperature of plasticity of the two different thermoplastic materials so that the fibres of one of the thermoplastic materials are rendered plastic and fused together, the other thermoplastic material retaining its fibre structure.
