Measurement of Capillary Spaces of Woven Fabric by Wicking Determination of Water into Samples

Abstract

A Technique based on electromagnetic field of wicked water used for measuring the distance of water rise in woven fabric samples as a function of time. Vertical wicking distance of water was obtained in weft direction of cotton fabric samples with different counts and densities of weft yarn. The effect of yarn count and density were studied in the wicking rise of water into fabric samples. By applying Washburn equation, the amount of geometrical constant factor; K= (γlv re .Cosθ/2η)=L2/t was evaluated from experimental results where, L= the height of liquid rise, t=time, re= equal radius of capillary, γlv=the surface tension, η=the viscosity and θ=the contact angle of the liquid-surface. Using the specification of water solution diluted of Diavadin UN detergent, geometric structural factor of constant parameter of capillary spaces of fabric samples were evaluated.
