Abstract
Abstract A surgical swab comprises a warp knitted body portion (1) and an integrally warp knitted handling tape (3). Both the body portion and the handling tape are formed as two superimposed layers on a twin needle bed knitting machine, the respective longitudinal and/or laterally extending edges of each layer being joined by interknitting. The swab may be cut from a continuous swab strip which is formed by continuously knitting a length of body portion fabric and of handling tape fabric with a lateral band of the fabrics being knitted together at intervals. Individual swabs are separated from the strip by cutting through the lateral band.
