Abstract (en)

[origin: WO9856326A1] Sheet material for absorbing liquid has a first fibre layer with a pattern of a modifying agent applied thereto, the modifying agent being substantially more hydrophobic or hydrophilic than the fibres, thus modifying the performance of the fibre layer. A method of modifying the absorbency and liquid flow characteristics of a non-woven fabric comprising: (i) procuring a non-woven textile fibre first sheet material; (ii) selecting a modifying agent which is substantially more hydrophobic or hydrophilic than the fibres of the non-woven sheet material; and (iii) applying the modifying agent to the non-woven sheet material in a pre-selected pattern. The material made is of particular use as an absorbent layer in an incontinence product or wound dressing, facilitating the spread of liquid throughout the layer.
