Abstract
Abstract The composite fusible interlining fabric is formed of a layer of nonwoven fabric, a layer of fibrous material positioned against the reverse or rear side of the layer of nonwoven fabric, stitch yarn knit through the layer of nonwoven fabric and the layer of fibrous material and securing them together, and a coating of thermoactive adhesive material on the front or face side of the layer of nonwoven fabric. The layer of nonwoven fabric provides a smooth surface for the coating of thermoactive adhesive material. Additionally, the layer of nonwoven fabric of closely compacted fibers provides a barrier or shield to prevent strike back of the adhesive coating material when the composite interlining fabric is fused to the base or garment fabric.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
217 words
A composite fusible interlining fabric adapted to be fused to a base fabric and characterized by the smooth surface characteristics of nonwoven interlining fabric and the strength, bulk, resiliency, and drapability characteristics of woven and knit interlining fabrics, said interlining fabric comprising a layer of nonwoven fabric of closely compacted fibers, a layer of inlaid weft yarns positioned against one side of said layer of nonwoven fabric, stitch yarn knit through said layer of nonwoven fabric and said layer of inlaid weft yarns and securing said inlaid weft yarns to said layer of nonwoven fabric, and a coating of thermoactive adhesive material on the side of said layer of nonwoven fabric opposite the side against which said layer of inlaid weft yarns is positioned, said coating of thermoactive adhesive material being fusible at a predetermined temperature which is lower than the temperature at which said layer of nonwoven fabric, said layer of inlaid weft yarns, said knit stitch yarn and the base fabric will be adversely affected, so that said composite interlining fabric may be fused to one side of the base fabric by the application of heat thereto, said layer of nonwoven fabric providing a barrier to prevent strike back of said adhesive coating material when said composite interlining fabric is fused to the base fabric.
Claim 2
Dependent Claim
