Abstract
A patterned pile fabric of stitch-bonded construction. The fabric includes a substrate layer with an arrangement of ground yarns extending in stitched relation through the substrate layer so as to define a ground covering across the substrate layer. An arrangement of pile forming yarns extend in stitched relation through the substrate layer such that the pile forming yarns define a patterned arrangement of looped elements projecting away from the ground covering in predefined three dimensional patterned arrays disposed across the fabric.
Claims23
A patterned fabric of stitch-bonded construction, the fabric comprising:
- a substrate layer;
- a plurality of ground yarns extending in stitched relation through the substrate layer so as to define a ground covering across the substrate layer;
- and
- a plurality of pile forming yarns extending in stitched relation through the substrate such that said pile forming yarns define a patterned arrangement of looped elements projecting away from the ground covering in predefined three dimensional patterned arrays disposed across the fabric.
A patterned fabric of stitch-bonded construction, the fabric comprising:
- a fibrous nonwoven substrate layer including a heat activated low melting point polymeric constituent;
- a plurality of ground yarns characterized by a first linear density and extending in stitched relation through the substrate layer so as to define a ground covering across the substrate layer;
- and
- a plurality of pile forming yarns characterized by a second linear density greater than the first linear density and extending in stitched relation through the substrate layer such that said pile forming yarns define a patterned arrangement of looped elements projecting away from the ground covering in predefined three dimensional patterned arrays disposed across the fabric and wherein at least a portion of the patterned arrays of said looped elements are separated from one another by a plurality of substantially two dimensional loop-free segments disposed along at least one of the machine direction and the cross-machine direction of the fabric.
A method of forming a patterned fabric of stitch-bonded construction, the method comprising the steps of:
- providing a substrate layer;
- inserting a plurality of ground yarns in stitched relation through the substrate layer so as to define a ground covering across the substrate layer;
- and
- inserting a plurality of pile forming yarns in stitched relation through the substrate in a predefined pattern such that said pile forming yarns define a patterned arrangement of looped elements projecting away from the ground covering in predefined three dimensional patterned arrays disposed across the fabric.
