An objective method to characterize moisture management properties of disposable diapers

摘要

This study provides an objective test method to characterize the dynamic moisture management properties of disposable diapers by the Moisture Management Tester (MMT), which is developed to evaluatemoisture transport properties of textiles in multi-directions. The MMT device can record the textile liquid transfer process dynamically and quantitatively, and the result is displayed by the figure of the moisture content change with test time elapsing. Six indices are specially extracted from the measurement curves, and five of themare selected finally to describe and predict the liquid moisture transfer properties of diapers more effectively. Moreover, measurement results showed that, except the pump time to the index of wetting time, all of the defined indices have significant correlation with diaper types and the liquid pump time level, and the extracted indices are sensitive enough to the variance of diaper types and pump time level. Therefore, the objective test method with MMTand the extracted indices can be used to characterize the moisture management properties of disposable diapers.
