The present invention provides a 3-layered wound dressing comprising two outer layers fabrics and one middle layer fabric. The density of the said two outer layer fabrics is greaterthan that of the middle layer. The weight of the two outer layerfabrics is between 8-140 gsm, density 0.08-0.32 g/cm3. The said dressing provides a good fluid and moisture retention property, allowing a large amount of wound exudates to be absorbed and contained within the middle layer and preventing the absorbed wound exudates to contaminate healthy skin.
