Abstract
A method () of manufacturing a wound dressing includes obtaining alginate fibers () and the step () of spraying either the alginate fibers () or a dressing or dressing layer () of the alginate fibers with an aqueous solution () comprising a polysaccharide, which can be carboxymethylcellulose. The step of spraying can occur while the alginate fibers, dressing, or dressing layer are wet. A step () of flash drying can follow to remove the solute of the aqueous solution to leave the polysaccharide along the alginate. The step of spraying can be selective, such that only portions of the dressing layer include the polysaccharide.
