Abstract
This invention relates to decorative sheet useful for making ribbons, bows, and the like. The invention relates to the field of synthetic textiles. The decorative sheet material comprises PA0 (a) a thermally bonded nonwoven tissue-like base layer having at least 50 weight percent polymeric, staple fibers having a length of 1/4 to 6 inches, and up to about 50 weight percent other fibrous material, at least the outer portion of said fibers being thermally bondable, and PA0 (b) at least a monolayer of a multiplicity of substantially parallel, continuous, non-cellulosic, multifilament yarns substantially covering a first side of said base layer and thermally laminated to said base layer, at least one side of said base layer being sonically bondable to a fibrous substrate. By making the base layer out of a sonically bondable material, articles made of the sheet material of this invention can be rapidly produced. The sheet material can be used to prepare such products as ribbon, pressure-sensitive adhesive tape, laminates, embossed products, and molded products.
