“…Specifically, the elongation was 211.57% ± 5.16% and 205.40% ± 7.56% when the inner wrapping density was 900 T/m and 1000 T/m, respectively, both higher than 800 T/m (Figure 2B). The larger elongation under higher inner wrapping density should be attributed to the enhanced wrapping angle, making wrapped filaments easier to deform along the axis of double-wrapped yarns [23]. However, two large frictions between the Spandex core and wrapped filaments generated under high wrapping density may also prevent the double-wrapped yarns from deformation.…”

Elastic yarns are the key component of high-performance compression garments. However, it remains a challenge to fabricate anti-fatigue yarns with high mechanical force and long elongation for generating compression garments with prolonged wear. In this paper, we report the development of anti-fatigue double-wrapped yarns with excellent mechanical properties by wrapping high-denier Spandex with nylon filaments in opposite twists. In particular, 560D high-denier Spandex as the core was untwisted which can maximumly reduce the interaction between the core and wrapping filaments, enabling high elongation of the double-wrapped yarns. In addition, we chose 70D nylon filaments with a tensile force of 387.40 ± 8.82 cN as the wrapping materials to provide sufficient force for double-wrapped yarns. Notably, opposite twists were induced for the inner and outer wrapping filaments to achieve a balanced stable yarn structure. By systematically optimizing manufacturing parameters including inner wrapping density, outer wrapping density, taking-up ratio, and drafting ratio, we obtained double-wrapped yarn with excellent tensile force (952.00 ± 24.03 cN) and elongation (357.28% ± 9.10%). Notably, the stress decay rate of optimized yarns was only 12.0% ± 2.2%. In addition, the optimized yarn was used as the weft-lining yarn for generating weft-lined fabrics, the elastic recovery rate of the obtained fabric was only 2.6% after cyclic stretching, much lower than the control fabric. Our design of anti-fatigue double-wrapped yarns could be widely used for fabricating high-performance compression garments.

“…[8][9][10][11] Besides, improving the hygroscopicity of yarns, water vapor transmission, and breathability is an effective way to gain absorption and quick-drying fabrics. [12][13][14] Also, the fabric structure and fabric treatment (sorting) or other factors affect the absorption and quick-drying ability of fabrics. [15][16][17] Relative to woven fabrics, the special coil structure of knitted fabrics is endows them with unique transmission properties, such as water vapor permeability, air permeability, thermal conductivity, water management, and so on.…”

Enhancing the thermal-wet comfort of garments is a key factor in sportswear research. In this study, we designed a new three-dimensional moisture conduction structure model, developed double-sided fabrics of a changed spacer weft-knitted structure, and compared them with single-sided plain stitch and cellular structure fabrics, focusing on the morphology, basic structural parameters and absorption, and quick-drying performance. The findings indicated that the changed spacer weft-knitted fabric consisting of 18 tex Tencel and 33.3 tex (96 f) recycled polyester filament has a smaller surface density and thickness, the water absorption of 436%, the water evaporation rate of 0.354 g/h, and the water vapor transmission of 7476.75 g/(m2 · d). Compared with other fabrics, it has excellent absorption and quick-drying performance. Partitioned T-shirts were designed by using the human body sweating law, and four fabrics were applied to one to four areas according to the sweating degree. Through infrared image monitoring and subjective evaluation, we concluded that the partitioned T-shirt has efficient absorption and quick-drying ability, and has potential to be applied to the development of thermal-wet comfort sportswear.

“…4,5 Textiles mixed with phase change materials provide an excellent cooling function, because there is significant decalescence of phase change when the temperature rises to a set value 6,7 according to the principle of energy conservation. Thus, the cooling sensation of fabric can be enhanced by improving heat conduction, moisture transfer and evaporation, 8,9 and using heat-absorption materials. Nowadays, some specific elements of the wet comfort of fabrics can be estimated, such as the liquid moisture transport property, moisture absorption and quick-drying capacity.…”

The evaluation of thermal-wet properties contributes to the research and development of fabrics, but there is no effective method to address and achieve evaluation of the hygroscopic and cooling properties of knitted fabrics to date. Therefore, an evaluation method aiming at this issue was proposed, and based on experimental investigation the hygroscopic and cooling property of fabrics was estimated by the combined evaluation of moisture management and the thermal property in a dynamic state. The moisture management property shows the liquid water absorption and diffusion performance of fabrics. Beside this, the thermal properties of fabrics were tested respectively in the dry and wet states. The thermal property of dry fabric showed the heat transfer and radiation of fabric itself, whereas the thermal property of wet fabric demonstrated the combined effect of the coupled heat–moisture property of wet fabric and the cooling function of moisture evaporation and diffusion. Furthermore, the thermal properties of fabrics were tested using a YG606 II thermal resistance tester, which was refitted by a program to control heating power. Eight knitted fabric samples having different cooling comfortability rates or values were selected to verify the feasibility and effectivity of this method. The consistency of this method was also verified by the obtained experimental results. Based on the obtained results, it can be observed that this method was well consistent with verified experimental results. Therefore, an effective method for the evaluation of hygroscopic and cooling knitted fabrics was obtained that satisfies the measurement of performance, and desirable fabric properties can be achieved for various applications.
