Abstract
Abstract A stretchable sliver knit upholstery fabric has a jersey backing formed of two types of body yarns. Each stitch of the jersey backing includes a stretch yarn knit under high tension and an inelastic yarn. The sliver knit pile fabric is given a light latex back coating to lock the pile fibers in place and to stabilize the fabric sufficiently to permit efficient finishing treatments and handling operations without materially impairing the capacity of the fabric to be conformed to the contours of molded furniture pieces.
