Claims9
An autoadhesive wound dressing which comprises a pad of highly absorbent alginate fibres, wherein the alginate fibres have an absorbency of at least 40 g of deionized water per gram of pad, one face of which pad is provided with an interrupted layer of a pressure sensitive adhesive, wherein the alginate fibres are characterised by having a split maxima in the range of 100.degree. C. to 400.degree. C. in a plot of the first order derivative of percentage weight loss of the fibre with temperature against temperature.
