Abstract
A lightweight, porous knitted elastic bandage is produced from a warp of false-twist synthetic yarns with a filling inlay of regular yarns. The filling yarns are arranged in varying patterns across the warp yarns so that a portion of their length lies in looped and cursive configuration upon the surface of the bandage, and the structure is so open that overlapping layers of the bandage cling to each other in substantially non-displaceable relationship.
Claims6
A self-supporting, open mesh knitted elastic bandage characterized by the tendency of overlapping layers of the bandage to cling to each other in relatively non-displaceable relationship, which comprises
- a set of composite parallel warp yarns comprising a first false-twist yarn formed into stitch loop chains with a second false-twist yarn inlaid into the loops of said first false-twist yarn,
- said second false-twist yarn being of opposite twist from the twist of said first false-twist yarn,
- and a plurality of individual filling yarns describing varied and cursive patterns across said set of composite warp yarns and being inlaid therewith,
- said varied and cursive patterns of filling yarns overlapping one with another across a substantial portion of the width of said bandage,
- no individual filling yarn pattern extending across more than a minor portion of the width of said bandage,
- and a portion at least of the length of said filling yarns lying in slack looped configuration on the surface of said bandage.
