Abstract:
An in-vitro method for determining an optimal combination of materials with respect to a particular menstrual flow condition for use in a feminine care absorbent article, said method comprising the steps of:selecting a subject flow rate corresponding to the flow rate of menstrual fluid for a particular menstrual flow condition; providing a simulated menstrual fluid to a flow rate controllable metering device; dispensing the simulated menstrual fluid onto a first combination of materials at the subject flow rate; observing whether the combination of materials adequately perform their intended purpose in the feminine care product at the subject flow rate; varying at least one of the materials in the combination and repeating the steps of dispensing the simulated menstrual fluid and observing the performance of the combination of materials; and selecting an optimal combination of the materials based on their performance when subjected to the simulated menstrual fluid at the subject flow rate.
