Sanitary napkin is worn in direct skin contact and is an essential product for most women. Its liquid transportproperties, depending on the material and design, affect skin wetness, skin irritating potential and comfortable feeling. Disposable sanitary napkin is commonly used whilst reusable sanitary napkin is also available in the market for sustainablereason. In this study, a measurement method originated from Forced Flow Water Transport Tester (FFWTT) was introducedwhich can characterize the direction of liquid transport of sanitary napkin under different pressure loadings. Disposablesanitary napkins with nonwoven or perforated film surface were compared against the reusable sanitary napkins. The resultsfound that the reusable sanitary napkins tend to accumulate more next-to-skin moisture than the disposable sanitary napkin atequivalent loadings. Also, its transplanar wicking is poor. Besides, disposable sanitary napkins incorporated withsuperabsorbent polymer provide acceptable liquid transport property whilst those made of flex foam give the bestperformance.

Instrumentation for Measuring the Wet Frictional Property of Sanitary Pads
Ka-Po Maggie Tang,Ching-Hei Li,Chi-wai Kan 한국섬유공학회 2020 Fibers and polymers Vol.21 No.1
Women wear sanitary pad for whole day during their menstruation period. They have direct skin contact with iteven for sleeping and exercising. The presence of sweat and menstrual blood increases the moisture level and the adhesion ofliquid to textile causing sensorial discomfort. This study describes the design and uses of modified Textile StickinessMeasurement System (TSMS) which can characterize the frictional properties of sanitary pads under both dry and wetconditions. The uniqueness of this measurement system is that the wetness level of the pad is adjustable and the surfaceprofile of the contacting object (i.e. Lorica®Soft) does simulate the condition of human skin. Also, it does not have restrictionon the type of sanitary pad that can be tested. Among the 12 sanitary pads tested (disposable and reusable types), the frictionalforce for the disposable sanitary pads is lower than the reusable pads whilst the performance of disposable sanitary pads withnonwoven surface is lower than the one with perforated surface. These can attribute to their liquid transport property andsurface feature. For those with better liquid transport property, less water will stay on skin surface and so the adhesionbetween skin and textiles is lower. For those with protruding fibers on its surface, it reduced the contact area and so thefrictional force is lower.
