Claims23
A wound dressing comprising a non woven web of gel-forming fibers comprising longitudinal lines of stitches formed from thread and transverse lines of stitches formed from thread extending between at least two longitudinal lines of stitches to form a stitched column between the at least two longitudinal lines of stitches, wherein the transverse lines of stitches are finished at an edge of the at least two longitudinal lines of stitches resulting in at least one stitch free column between stitched columns.
A method of manufacturing a wound dressing for use in cavity or sinus wounds wherein the method comprises the steps of:
- (i) forming a roll of fabric comprising a non woven web of gel-forming fibers;
- (ii) stitching the roll with longitudinal lines of stitching formed from thread;
- (iii) stitching the roll with transverse lines of stitching formed from thread extending between the longitudinal lines of stitches to form a stitched column and are finished at an edge of at least two longitudinal lines of stitches resulting in stitch free-columns between stitched columns;
- and (iv) slitting the roll in a longitudinal direction in the stitch free columns.
A wound dressing comprising a non woven web of gel-forming fibers, transverse lines of stitches extending between longitudinal lines of stitches to form columns separated by at least one-stitch-free column, wherein transverse lines of stitches are finished at an edge of at least two longitudinal lines of stitches, and wherein the transverse lines of stitches are stitched through the wound dressing.
