Claims18
A wound dressing having a non-woven web of gel-forming fibers, the wound dressing comprising:
- longitudinal lines of stitches formed from thread;
- transverse lines of stitches formed from thread extending between at least two of the longitudinal lines of stitches to form a stitched column;
- and
- at least one stitch free column;
- wherein at least two stitched columns are formed and separated by the at least one stitch free column;
- wherein two of the transverse lines of stitches are offset from one another in a longitudinal direction by an offset distance;
- and
- wherein a longitudinal length of the at least one stitch free column is greater than the offset distance.
5 more elements
A method of manufacturing a wound dressing, the method comprising:
- forming a first roll of fabric comprising a non woven web of gel-forming fibers;
- forming a first stitched column formed by longitudinal lines of stitches having transverse lines of stitching formed from thread extending between the longitudinal lines of stitches, wherein two of the transverse lines of stitching are offset from one another in a longitudinal direction by an offset distance;
- and
- forming a second stitched column spaced from the first stitched column to create a stitch-free column between the first stitched column and the second stitched column;
- wherein a longitudinal length of the stitch-free column is greater than the offset distance.
2 more elements
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;
- wherein the 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.
