Abstract
Abstract A dry cleanable self-lined unfinished lustrous antique satin fabric having good hand, good crease resistance, and a woven look is provided. The fabric is a weft inserted warp knit (wiwk) fabric which has a multiple substrate, a single substrate with foam backing, or a single substrate with an additional sewn lining. The weft yarn is on the face of the substrate, and is a lustrous yarn such as rayon (as when producing non-washable draperies), or acrylic, bright polyester or acetate (as when producing washable draperies). The weft has a density equivalent to between about 36-52 single picks per inch, and at least part of the weft may comprise a novelty yarn. The warp yarn is stitching yarn, in a tricot stitch configuration. The warp yarn is a low-shrinkage filament yarn that is not fully oriented, and has a denier of between about 20-60, and an elongation of at least 15 percent. Non-woven inexpensive polyester substrate may be utilized; if a single layer is utilized it has a maximum weight of 2.0 ounces per square yard, and if a multiple substrate is utilized each layer has a maximum weight of between about 0.5-1.0 ounces per square yard.
