Definitions
- a flow versus pressure relationship for the wet sample can be established and compared to the results for the dry sample.
- the mean flow pore size is measured at the point where the curve representing 50% of the dry sample flow versus pressure intersects the curve representing wet sample flow versus pressure.
- the diameter of the pore which opens at that particular pressure i.e., the mean flow pore size
- the present invention addresses the needs discussed above by providing a liquid transport material composed of pulp fibers hydraulically needled into a nonwoven fibrous structure so that the material is adapted to have a liquid transport value of at least 12 grams of liquid per gram of material over 30 minutes.
- the liquid transport material has a liquid transport value of at least about 15 grams of liquid per gram of material over 30 minutes. More desirably, the liquid transport material has a liquid transport value ranging from about 17 to about 25 grams of liquid per gram of material over 30 minutes.
- the liquid transport material may have a specific volume ranging from about 8 to about 15 cm 3 /g and/or a vertical wicking height of at least about 18 cm per 15 minutes.
- Q volumetric flow rate of water expressed in cubic feet per minute per orifice
- the liner layer 102 is a topsheet
- the fluid-impervious bottom layer 108 is a backsheet
- the liquid transport layer 104 is a liquid distribution layer
- the absorbent layer 106 is an absorbent core.
- Each layer may be separately formed and joined to the other layers in any conventional manner. The layers may be cut or shaped before or after assembly to provide a particular absorbent personal care product configuration.
