Design and development of multipurpose absorption rate meter

Abstract

A Multipurpose Absorption Rate Meter (MARM) has been designed and developed for measuring the absorption rates of different fabrics and towel samples. MARM, designed to measure absorbency by Capillary Travel Method, works on electrical resistance principle. It records the vertical wicking height of the test sample, thereby, displaying the absorption rate in seconds. Measurements were made for 100% cotton, cotton/polyester and polyester/viscose blended fabrics at 1, 2 and 3 cm heights. Results indicate that wicking slows down as height increases. Absorption rates recorded for warp-wise and weft-wise strips were found to be different. Fabric finishing, yarn count, thickness, crimp and crease affect the wickability. MARM can accurately make measurements for yarns, writing and computer papers, and commercial absorbents.
