Subjected to various dynamic stresses, elastic sportswear exhibits a relatively complex structure. However, most existing studies on the wicking behavior of elastic yarns are conducted under infinite liquid supply conditions, which do not realistically reflect the finite perspiration conditions of the human body. Furthermore, there is a lack of systematic investigations into the wicking behavior of single yarns, plied yarns, and interlaced structures under varying stretching states. In this study, an experimental platform was developed to simulate human perspiration in the form of microdroplets, and the wicking performance of polyester elastic filaments, piled yarns, and plain-woven interlaced networks under various stretching states was systematically investigated. The results indicated that stretching reduced both the yarn diameter and average hydraulic diameter. Moderate stretching improved the wicking length of both single and plied yarns, although a peak value was observed. Increases in twist level and stretch both reduced the initial wicking rate of plied yarns, while a higher number of plies mitigated the negative effects of high twist and stretching. The wicking length of plied yarns was generally greater than that of single yarns, and a significant positive correlation was observed between them. Moreover, the Lucas–Washburn equation demonstrated strong applicability for predicting the initial wicking behavior (1 s) under finite droplet conditions, although its applicability range of average hydraulic diameter depended on droplet volume. Simulations using Ansys software also showed strong agreement with experimental results. A significant negative correlation was observed between wicking length (120 s) and average hydraulic diameter. In the woven network, liquid preferentially diffused rapidly along yarns under lower stretch and then penetrated from the interlacing points into yarns under higher stretch. As the stretch difference between warp and weft yarns increased, the transfer of liquid from highly stretched yarns to those with lower stretch was significantly reduced. Additionally, the wicking lengths of the warp and weft yarns were strongly correlated with the wicking lengths of their corresponding plied yarns. This study systematically elucidated the mechanisms by which stretching influences the wicking performance of polyester elastic yarns under finite droplet conditions. The wicking behaviors of single yarns, piled yarns and woven networks under various stretch states were correlated, thus advancing theoretical understanding of liquid transport at the yarn level in elastic sports textiles. In addition, a preliminary simulation method for yarn wicking behavior was developed, providing both experimental evidence and theoretical support to facilitate the development of yarn-network-based ca","PeriodicalId":278,"journal":{"name":"Colloids and Surfaces A: Physicochemical and Engineering Aspects","volume":"726 ","pages":"Article 137783"},"PeriodicalIF":4.9,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144662243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their impact on fluorocarbon surfactant systems remains insufficiently explored. This study chose 1-octanol, 1-decanol, and 1-dodecanol as stabilizers, investigating their effects on surface activity, interfacial activity, spreading performance, viscosity, bubble evolution, and drainage property in foam solution containing short-chain fluorocarbon surfactant. The result indicates that long-chain alcohols competitively displace surfactants at interfaces, reducing surface and interfacial activities. Meanwhile, interfacial alcohol adsorption elevates surfactant concentration in aqueous phase, promoting surfactant/alcohol micellization and increasing viscosity. 1-Dodecanol, with high hydrophobicity, triggers phase separation above 3 mmol/L, inducing the highest viscosity elevation. Long-chain alcohols exert dual effects on bubble evolution, with critical concentrations (1-octanol: 3 mmol/L, 1-decanol: 1 mmol/L, 1-dodecanol: 1 mmol/L) serving as thresholds. At or below these thresholds, interfacial alcohol adsorption and synergistic micellization strengthen foam films and inhibit gas diffusion, retarding bubble coarsening. Above thresholds, excessive alcohols accelerate bubble rupture. The drainage analysis reveals that 1-octanol and 1-decanol effectively stabilize foam through viscosity enhancement and coarsening inhibition, while 1-dodecanol exacerbates foam drainage and destabilization. The foam solution with 3 mmol/L 1-octanol exhibits the optimal characteristics, with a surface tension of 22.00 mN/m, 25 % drainage time of 61.83 s, and spreading coefficients of 4.27 mN/m with diesel and 3.28 mN/m with cyclohexane.
