A cleaner wearable cotton which has the properties of one-way water transfer and resisting external liquid contamination was fabricated in this study. Wet plasma combined with fluorine-free hydrophobic agent (WP-FfHA) was used as an environmental-friendly technology in the preparation process. Other than the attribute of environmental protection, it was proved that wet plasma can not only reduce the consumption of water-repellent agent by 25 %, but also significantly improve the waterproofness of fabric through contact angle measurement. Water-drip test was used to determine the asymmetric wettability of the fabric. The results display that the water droplets were transferred from the undersurface to the top surface within less than 3 s through wicking zones, even under the condition of reverse gravity. Meanwhile, the liquids on the upper surface were not able to reverse-penetrate to the bottom. Scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) were employed to analyze the micro-topography and chemical construction of the wicking and non-wicking areas on the fabric surface. Tests for fastness showed that the fabric maintained a contact angle of 145 ° after 5 times of regular soaping. Investigation of breathability and mechanical property confirmed that the wearability of the cleaner directional moisture-transfer fabric was not adversely affected by this novel modification approach.

本研究制造了一种具有单向水传输和抵抗外部液体污染特性的清洁可穿戴棉。湿等离子体结合无氟疏水剂（WP-FfHA）在制备过程中被用作环保技术。除了环保属性外，经证实，湿等离子体不仅可以减少25%的拒水剂用量，而且通过接触角测量显着提高织物的防水性。滴水试验用于确定织物的不对称润湿性。结果表明，即使在反向重力条件下，水滴也能在不到 3 秒的时间内通过芯吸区从下表面转移到上表面。同时，上表面的液体不能反向渗透到底部。采用扫描电子显微镜 (SEM) 和 X 射线光电子能谱 (XPS) 来分析织物表面芯吸和非芯吸区域的微观形貌和化学结构。牢度测试表明，织物在常规皂洗5次后仍保持145°的接触角。透气性和机械性能的研究证实，这种新型改性方法不会对更清洁的定向湿气传输织物的耐磨性产生不利影响。采用扫描电子显微镜 (SEM) 和 X 射线光电子能谱 (XPS) 来分析织物表面芯吸和非芯吸区域的微观形貌和化学结构。牢度测试表明，织物在常规皂洗5次后仍保持145°的接触角。透气性和机械性能的研究证实，这种新型改性方法不会对更清洁的定向湿气传输织物的耐磨性产生不利影响。采用扫描电子显微镜 (SEM) 和 X 射线光电子能谱 (XPS) 来分析织物表面芯吸和非芯吸区域的微观形貌和化学结构。牢度测试表明，织物在常规皂洗5次后仍保持145°的接触角。透气性和机械性能的研究证实，这种新型改性方法不会对更清洁的定向湿气传输织物的耐磨性产生不利影响。
