Abstract
Official abstract text for this publication.
A material for use as a wound dressing, the material being in the form of a roll and comprising gel forming fibers and the material having lines of longitudinal stitching.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of manufacturing a material for use as a wound dressing comprising the steps of: a. forming a roll of fabric comprising gel forming fibers; and b. stitching the roll with lines of longitudinal stitching, wherein the stitching is made in a heat sensitive yarn. 2. The method as claimed in claim 1 wherein the roll of fabric is formed by making a non-woven web of gel forming fibers. 3. The method as claimed in claim 2 wherein the non-woven web is made by hydroentangling a web of gel forming fibers and carboxymethylating the hydroentangled web. 4. The method as claimed in claim 1 wherein the roll of fabric is formed by knitting a strip of gel forming fibers. 5. The method as claimed in claim 1 wherein the method comprises the further step of treating the material with a source of silver to give antimicrobial properties to the material. 6. The method as claimed in claim 1 wherein the material is heated after stitching. 7. The method as claimed in claim 1 wherein the method comprises the further steps of: a. cutting lengths from the roll; and b. joining the lengths together along their long edges to increase the width of the material. 8. The method as claimed in claim 1 wherein the method comprises the further step of cutting shapes from the roll. 9. The method as claimed in claim 8 wherein the method comprises the further step of joining the shapes together to form a three dimensional garment.
