FLUID DISTRIBUTION MATERIALS WITH IMPROVED WICKING PROPERTIES

摘要

PURPOSE: The fluid distribution materials with improved wicking properties are to provide the selection of materials which are particularly useful as fluid distribution material for being used in disposable absorbent articles, and to improve both wicking high and cumulative flux. CONSTITUTION: The fluid distribution materials have one of preferential fluid distribution direction, can particularly select useful materials, and have a wicking time of less than 120 seconds and a cumulative flux of more than 0.075 grams/cm¬2 second for said preferential fluid distribution direction at 12.4 cm height, when applying the Vertical Wicking Test. A further useful selection criterion for such materials is a fluid distribution behaviour,expressed in that the wicking time in the preferential distribution direction is less than 80 % of the wicking time of perpendicular direction at 8.3cm height, when applying the same test
