Directional water transport tester (DWTT) for fabrics

This Directional Water Transport Tester(DWTT) is a sensitive, accurate and reliable instrument for fabrics' water absorption and transport measurements developed by researchers at The Hong Kong Polytechnic University. DWTT's measurements are based on gravimetric and image analysis of water absorbed by a fabric. Then it can trace the direction of water spread and measure the amount of water transported on the skin. The DWTT can release water continuously and controllably to simulate different sweating levels. The DWTT measurement is fast and cost-effective. With this instrument, textile industry can characterize fabrics efficiently. It helps product developers to select suitable fabrics for different garments.
