Patent ID: 7901740

Claim:
A method for producing a stretchable workpiece, said method comprising the steps of: (a) coating a surface of a wall with a wetting agent; (b) applying a first layer of loose fibres onto at least a portion of the surface of the wetting agent coated wall, in a manner that the loose fibres are anchored in said wetting agent and held by it at substantially upright position relative to the wall surface, the fibres partially covered by the wetting agent, to produce at least a partially fibre-coated surface; and (c) spraying a liquid product material onto the uncovered top of said substantially upright standing fibres to form a product material layer on the fibre-coated surface and produce a stretchable workpiece comprising a porous or micro-porous web of partially connected droplets of product material having fibres partially embedded thereto, wherein the workpiece has an inner surface and an outer surface and the fibres are attached to the inner surface of the workpiece facing the wall and wherein said spraying of liquid product material is carried out by controlling spray intensity, droplet size, or surface tension of the product material.
