Abstract:
This invention relates to a wound dressing (10). The wound dressing includes first and second absorbent layers (12, 14) of a non-woven fabric of viscose and polyester fibres. Each absorbent layer has an operatively inner face (20, 26) and an operatively outer face (18, 22). The first and the second absorbent layers are bonded together with their operatively inner faces in face-to-face relationship, such that the absorbent layers together form a pad. The bonding between the first and second absorbent layers may be effected by a needle-punching process in which the needle punching density is no more than 400 punches/cm2. The wound dressing further includes a third layer (16) sandwiched between and bonded to the first and second absorbent layers. The third layer is in the form of cotton gauze. The invention extends to a method of making a wound dressing, and to a method of treating a wound.
