Beschreibung
Zusammenfassung:	The present invention discloses a 3-layered wound dressing and its method of manufacturing. The dressing comprises a wound contact layer, absorbent middle layer and outer layer. The said wound contact layer is a nonwoven made of a blend of hydrophilic fibres and hydrophobic fibres. The said absorbent middle layer is also a nonwoven made of another blend of hydrophilic fibres and hydrophobic fibres. The said outer layer is a hydrophobic nonwoven. The said wound dressing can transfer the fluid vertically so that the wound exudates can be absorbed and transferred to the middle layer, preventing the maceration of the surrounding skin. The said wound dressing can be used in the management of chronic wounds, particularly for heavy draining wounds.
