Abstract
Abstract A ribbon-like bandage fabric which is stretchable in the lengthwise direction but substantially unstretchable in the widthwise direction. The fabric includes a plurality of walewise parallel stitch loop chains knit of stretchable yarn, a pair of filling yarns extending back and forth across the fabric and being held in the courses of the stitch loop chains, and elastic yarns inlaid in and extending along selected ones of the parallel stitch loop chains. This knit bandage fabric is lighter weight than conventional woven bandage fabric but has substantially the same elastic characteristics and may be produced in a more economical manner.
