Superhydrophobic fabrics suffer from issues, such as poor breathability, surface color and handle changes, and toxicity because of additional chemical coating. Therefore, to resolve these issues, colorful fluorine‐free superhydrophobic polyester fabrics are prepared by controlling the conditions of a conventional disperse dyeing process. Alkaline hydrolysis, a pretreatment process in the dyeing process, is modified to create nanocraters on the surface of microrough polyester fabric. Then, the hydrolyzed polyester fabric is dyed with two different dyestuffs accompanied by thermal aging to lower the surface energy. The developed polyester fabrics become superhydrophobic and show the static contact angles over 160° and the shedding angles below 10°. Furthermore, the superhydrophobic polyester fabric exhibits improved color fastness as well as water vapor transmission rate and air permeability, while the handle properties of the alkaline‐hydrolyzed polyester fabric remain unchanged after dyeing and thermal aging. Finally, the self‐cleaning ability of the developed fabric is demonstrated by perfectly removing silicon carbide particles from its surface. Therefore, the developed fluorine‐free and superhydrophobic polyester fabric not only has color but also is nontoxic and environmentally friendly and can be readily recycled as it has no coated chemical to be removed. Thus, it has great potential for practical applications.

通过分散染色工艺制备的彩色无氟超疏水聚酯织物

超疏水性织物存在问题,例如透气性差,表面颜色和手感变化,以及由于额外的化学涂层导致的毒性。因此,为解决这些问题,通过控制常规分散染色工艺的条件来制备彩色无氟超疏水聚酯织物。碱水解是染色过程中的预处理过程,经过改性后可在微粗糙的聚酯织物表面上形成纳米坑。然后,将水解的聚酯织物用两种不同的染料染色,并进行热老化以降低表面能。所开发的聚酯织物变得超疏水,并显示出超过160°的静态接触角和低于10°的脱落角。此外,超疏水聚酯织物表现出改善的色牢度以及透湿率和透气性,而碱水解聚酯织物在染色和热老化后的手感保持不变。最后,通过从织物表面完美去除碳化硅颗粒,可以证明所开发织物的自清洁能力。因此,开发的无氟超疏水聚酯织物不仅具有颜色,而且无毒且环保,并且由于无需去除任何涂层化学物质而易于回收利用。因此,在实际应用中具有很大的潜力。完美去除织物表面的碳化硅颗粒可证明其具有自洁能力。因此,开发的无氟超疏水聚酯织物不仅具有颜色,而且无毒且环保,并且由于无需去除任何涂层化学物质而易于回收利用。因此,在实际应用中具有很大的潜力。完美去除织物表面的碳化硅颗粒可证明其具有自洁能力。因此,开发的无氟超疏水聚酯织物不仅具有颜色,而且无毒且环保,并且由于无需去除任何涂层化学物质而易于回收利用。因此,在实际应用中具有很大的潜力。
