The Wicking of Water in Yarn as Measured by an Electrical Resistance Technique

摘要

An apparatus was developed to study water-transport behaviour along yarns. The rise of the liquid water in the yarn triggered an electrical circuit which was coupled with a personal computer, and so the distance of water rise as a function of time was determined. To smooth the data, the method of least squares was applied and the theoretical equation of the flow through the vertical cylindrical capillary was used.
