Abstract
Abstract A non-woven material is applied to the surface of a woven scrim. The non-woven material is needle-bonded to the scrim. The composite structure is then embossed. The embossed pattern is placed by a heated embosser on the finished product and in the non-embossed areas, the heat of embossing causes the non-woven material to partially melt and assume a textured effect which mirrors the texture of the woven scrim.
