The use of more toxic reagents in the finishing of superhydrophobic cotton fabrics is one of the main factors that limit the application of the fabrics. Therefore, a green and sustainable method for preparing superhydrophobic cotton fabrics is urgently needed. In this study, a cotton fabric was etched with phytic acid (PA), which can be extracted from plants, effectively improving the surface roughness of the fabric. Subsequently, the treated fabric was coated with epoxidized soybean oil (ESO)-derived thermosets and then covered with stearic acid (STA). The finished cotton fabric exhibited excellent superhydrophobic properties, with a water contact angle of 156.3°. The superhydrophobic coatings of the finished cotton fabric endowed the fabric with excellent self-cleaning properties, irrespective of the liquid pollutant or solid dust. In addition, the inherent properties of the finished fabric were largely retained after the modification. Therefore, the finished cotton fabric with excellent self-cleaning properties has great potential for applications in the household and clothing fields.
在超疏水棉织物的后整理中使用更具毒性的试剂是限制其应用的主要因素之一。因此，迫切需要一种绿色可持续的方法来制备超疏水棉织物。在本研究中，使用植物中提取的植酸（PA）对棉织物进行刻蚀，从而有效提高了织物的表面粗糙度。随后，用环氧大豆油（ESO）衍生的热固性树脂对处理后的织物进行涂覆，然后再用硬脂酸（STA）覆盖。整理后的棉织物表现出优异的超疏水性，水接触角为 156.3°。整理后的棉织物的超疏水涂层赋予了织物优异的自清洁性能，无论是液体污染物还是固体灰尘都能有效清洁。此外，整理后的织物基本保留了其固有性能。因此，具有优异自清洁性能的整理棉织物在家庭和服装领域具有很大的应用潜力。
