“…There are many alternative wicking test methods. Perwuelz et al [21] used an image analysis method to investigate the capillary rise of coloured liquid in yarns structure. Another method deals with measuring water transport along textile fibres by an electrical capacitance that consists of the construction of an apparatus with a specially designed electrical amplifier circuit and condenser electrodes, between which sample fibres are placed [7,26].…”

Liquid moisture transport of textile structures has been studied in order to manage human perspiration well. This article deals with investigation of dynamic moisture transport of knitted fabrics by sophisticated methods, such as moisture management tester (MMT), thermography and microtomography systems. Three groups of knitted fabrics were analysed by the above-mentioned methods. Specifically, the distribution of liquid drops on samples was compared with the results of vertical wicking of tested materials and the parameter of three-dimensional fabric porosity. Both dynamic spreading of liquid drops on the surface of samples (from top and bottom sides simultaneously) and vertical wicking behaviour of textiles were analysed by the combination of thermography and image analysis system. Further, the results from MMT and porosity analysis by microtomography system were investigated to specify the interaction between structure parameters of knitted fabrics and their liquid transport properties which influence total wear comfort.

“…The constituent yarns are responsible for the main portion of the wicking action, in capillary flow through textile fabrics [6,7]. In many researches, the textile yarns were treated either as porous media [8][9][10], the liquid transport through which is described by Darcy's law [11], or as capillary tubes [12][13][14][15], the liquid flow through which can be modeled by Lucas-Washburn kinetics [16]. In the first case, the characteristic parameters, such as permeability, are difficult to quantify and are obtained empirically.…”

“…The effective capillary radius is not calculated by fitting the experimental data; it is dependent on the geometrical conformation [18]. It was reported by various researchers that wicking depends on tortuosity of fabric [6,7,14,19] and this factor was incorporated in single jersey knitted fabric [18].…”

This paper aims to investigate vertical wicking properties of polyester fabric based on change in sample direction and change in tension. Also experimental results are compared with theoretical results. Polyester fabric made out of spun yarn with four types of variation in pick density was used. Theoretical values of vertical wicking were calculated by using Lucas-Washburn equation and experimental results were recorded using strip test method. Maximum height reached experimentally in both warp way and weft way is more than that of the theoretical values. The maximum height attained by fabric experimentally in weft is more as compared to warp way. Vertical wicking increases with increase in tension. This paper is focused on wicking which plays a vital role in determining comfort and moisture transport behavior of fabric.

Liquid transport and movement in yarns were studied using an experimental system based on the analysis of charge couple device images taken during the capillary rise of a colored liquid in the yarn. The generalized dynamic model of the liquid penetration into vertical cylindrical capillary used was based on the Lucas-Washburn equation. It had the advantage of independently characterizing the equivalent pore radius and the contact angle by determining the coefficient of diffusion of the liquid noted D and the height attained at equilibrium noted h e . We studied cotton and viscose yarns and found that the diffusion of liquid and the height attained at equilibrium depending on the fiber type. These results were discussed on the basis of the wettability of the fibers. We used water and a chemical agent added to water to investigate the effect of the characteristics of liquid on the capillary rise in yarns. The capillary parameters values (D and h e ) depended on the concentration of the chemistry agent added to water. These results were discussed by studying the evolution of the characteristic of the porous media and the liquid properties by calculating the equivalent pore radius and the contact angle and measuring the surface tension and the viscosity of the fluid.
