Novel moisture management test of polyethylene terephthalate and nylon fabric under stretching and surface patterning

Wet comfort is an important indicator for evaluating human wearing comfort, and personal moisture management fabrics can quickly transfer sweat from the skin surface to meet the human body's requirements for wet comfort. Although cotton fabrics have an excellent water absorption capacity, the inability of moisture to transfer quickly causes the fabrics to cling to the skin and causes discomfort. Here we demonstrate personal moisture management cotton fabric by two-step grafting treatments, which are relatively simple and usually do not fall off as easily as a simple coating process. Moreover, unlike traditional double-layer or sandwich structures that absorb water and grow heavy, the fabric's quick-drying qualities are accomplished by expanding the area of water evaporation. According to the results of liquid moisture management and water evaporation rate tests, this fabric's moisture diffusion radius is 5 mm larger than that of pure cotton fabrics, and its evaporation rate can reach 0.2082 g/(m2 · d). In addition, it is also suitable for high-volume apparel fabrics. This work paves the way for personal moisture management cotton fabric.

Simple post-treatment of cotton fabric for efficient personal moisture management

et al. 2023

“…Wet comfort is considered as one of the most important characteristics reflecting textile performance during wearing. 1,2 Scientifically, wet comfort is commonly defined as moisture management ability, 3,4 and it can be characterized quantitively by a moisture management test, 5 which is an effective method to analyze this characterization and has been used widely in recent research. [6][7][8][9] In the textile industry, cotton is the most popular natural material and is applied widely because it is soft, comfortable, and breathable.…”

Electrospun nanofiber/cotton composite yarn with enhanced moisture management ability

et al. 2021

Wet comfort is a critical performance for fabrics, especially when human bodies release sweat in daily life. Despite excellent moisture absorption performance, cotton yarns are still limited in the moisture release/transfer ability. Here, based on a novel electrospinning technology, polyacrylonitrile and polystyrene (PS) electrospun nanofiber/cotton composite yarns were produced, respectively. Under fluorescence microscopic observation, electrospun fibers within the composite yarns showed a uniform distribution. As a result, these composite yarn-based knitted fabrics obtained a good water transport ability and a fast water evaporation rate. According to the moisture management test, PS electrospun nanofiber composite yarn-based fabrics exhibited a relatively high one-way transport index R (400%), claiming an enhanced moisture management performance. Finally, specific surface area tests and finite element analyses were used to analyze the water transport mechanism inside the yarns. The results proved that a small number of electrospun fibers played a predominant role in enhancing the moisture management ability of the composite yarns.

“…The mutual interaction between liquid and a fabric depends on the hydrophilicity or hydrophobicity of the constituent fibers, the surface geometry characteristics of the yarn/fabric assembly, the volume (or droplet size) and character of the liquids and some external factors (e.g., the tension applied to a fabric, environmental conditions). 1,2,[7][8][9][10][11][12] Recent advances in work with respect to the transverse wicking behavior of textile fabrics are as follows. For example, a cyclic stress instrument was developed by Raja et al, 12 and the effect of parameters (e.g., extension rate, cyclic extension percentage and liquid flow rate) on the transverse wicking behavior of cotton/Lycra knitted fabric was studied.…”

Exploring the transverse wicking behavior of mechanically robust warp super-elastic woven fabric for tight-fitting garments

et al. 2021

The ability of a fabric to wick moisture away from the human body directly determines the moisture management ability of any given textile, and thereby has a great influence on the comfort offered by garments made from that textile. In this paper, the effects of tensile extension and liquid drop height on the transverse wicking behavior of a warp stretch woven fabric were systematically investigated. By virtue of the unique structure of the nylon/spandex air-covered warp yarn, the woven fabric has a denser and tighter surface, which facilitates its warp elastic stretchability beyond 60%. Furthermore, an acceptable cyclic tensile behavior at an extension of 30% was obtained, indicating the superior mechanical robustness of the fabric to a certain extent. The experimental results demonstrated that the transverse wicking performances of the fabric, including the wetting time and liquid spreading area, were dependent on the tensile extensions and the heights between the water droplet and the fabric surface. Specifically, the wetting time increased with an increase of tensile extension or a decrease of liquid drop height. The spreading area of the water droplet increases as a function of the wicking time, and it fits a power relation appropriately. In addition, the water vapor transmission behavior of our fabric during stretch was clarified. Such work is essential to get an in-depth evaluation of the wicking behavior of complex stretchable fabric structures.
