“…In the case of filament yarns, the wicking height first increases and then decreases with increasing twist level [14]. In contrast, for staple yarns, an increase in the twist level (from 325 to 400 twist coefficient) decreases the wicking heights of the viscose ring-spun yarns [11].…”

“…Previous work on the wicking properties of staple yarns has produced a mathematical model for yarn wicking [2,6]. With increasing twist factor and packing density, the wicking height of lyocell and viscose ring-spun yarns decreases [1,11]. Knitted fabrics made from polypropylene show better moisture transport properties than PET [7].…”

“…On the basis of the above analysis, staple yarns should follow the same trend as filament yarns; however, previous research has not tested this systematically. The twist levels selected have been limited to short sections [1,11], and the integral influence of the twist effects on the wicking property of the staple yarns has not been expressed accurately. In this study, the twist effects on the wicking property of staple yarns were investigated experimentally.…”

In this study, the wicking properties of ring and compact-siro ring spun staple yarns were compared. The twist level, which is related to the structure of the staple yarns, was found to significantly influence the wicking property of the two kinds of yarn. Polyester staple fibers with 1.33 dtex × 38 mm were selected as the staple fiber material, and the effect of the twist level on the wicking property was investigated using the capillary rise method. The results show that with a decreasing twist coefficient, the wicking height increases with a decrease in yarn compactness. The compact-siro spun yarn showed better wicking properties owing to it special ply yarn structure. Furthermore, the tension property of the yarns decreased significantly with a decrease in the twist coefficient. Compact-siro spinning was carried out to obtain staple yarns with lower twist coefficients, and the yarns showed great improvement in terms of yarn strength, fiber straightness, and wicking properties. Thus, compact-siro spinning is an efficient method to improve the wicking properties of staple yarns.

“…The manual visible light imaging technique was applied to different fabrics using water as wicking liquid in Harnett and Mehta, 9 Ferrero, 12 Ozturk et al 13 and Sampath et al 14 At the yarn scale, visualization is usually performed with some form of magnification optics. Different yarn materials have been imaged with water (see Figure 2), [15][16][17][18] lubricant liquids 19 or spin finish solutions. 20 Sometimes the manual method with colorants is used as a backup to another measuring method.…”

This review covers imaging techniques of wicking in textiles ranging from visible light to synchrotron x-ray. First, the wicking phenomenon and its relevance are exposed. Then, the main wicking experimental setups, namely the strip test and the spot test, are described. Next, the imaging techniques are described together with the relevant studies applied to wicking. Finally, the analysis of wicking measurements is presented. The conclusion presents imaging techniques applied to wicking in a historical perspective and highlights areas where further development is desirable.

We investigate wicking in textiles using neutron radiography on fabrics of two types, woven and simple jersey knit, and made of yarns of four different materials: cotton, polyethylene terephthalate, polyamide and polypropylene. Moisture distribution in the samples is quantified from the images, and the total mass is compared with gravimetric measurements for validation. The position of the front versus time is obtained from segmented neutron images and backlight images, with good agreement between the two measurement methods. Using a power law to fit the height versus time curves, values for the wicking ratio are found to depart substantially from the 0.5 predicted by the Lucas-Washburn equation. The sharp front approximation is found to be a good approximation for slow wicking fabrics but is an incomplete description of the moisture on high absorbing fabrics such as cotton. The variation of yarn material is the main contributor to the difference of wicking ratio among samples. Finally, neutron moisture profiles complemented with X-ray tomography allow to differentiate two regions in cotton wetted by wicking: intra-yarn wetting and wetting covering the yarns and the inter-yarn voids.
