Abstract: Multi component fibres for the reduction of the damaging activity of wound exudate components such as protein degrading enzymes and inflammatory mediators in wounds, the fibres comprising: from 10% to 100% by weight of the fibres of pectin and a sacrificial proteinaceous material in a weight ratio of 100:0 to 10:90 pectin to sacrificial proteinaceous material and from 0% to 90% by weight of the fibres of another polysaccharide or a water soluble polymer.

Abstract: A chemically modified cellulosic fibre or filament having a moisture content of at least 7% by weight obtained by a process comprising the steps of (i) obtaining cellulosic fibres or filament and chemically modifying the cellulose by substitution to increase its absorbency; (ii) washing the fibres after step (i) in a mixture comprising water and up to 99% by weight of water-miscible organic solvent; (iii) drying the fibres to a moisture content of at least 7% by weight.
