An improved test method for characterizing the dynamic liquid moisture transfer in porous polymeric materials

In order to evaluate the moisture management capacity of porous polymeric materials such as fabrics, a new test method and an instrument called the moisture management tester (MMT) have been developed. Derived from the measurement curves, 10 indices are defined to characterize the fabric liquid moisture management properties. In the improved test method, six indices are re-defined. The grading and classification methods are studied to give a direct overall evaluation and result for the liquid moisture management properties of the tested fabrics. Also, an improved sensor design, data processing method and expression of test results for the fabric moisture management properties are introduced. The MMT provides an objective measurement of comfort for those fabrics claimed to have excellent moisture management properties. It also provides a detailed and reliable method for production quality control, new product development and quality assurance by the retailer.
