The fouling of surfaces such as textiles is a major health challenge, and there is a continuous effort to develop materials and processes to overcome it. In consideration of this, this study regards the development of antifouling functional nanoencapsulated finishing for the cotton textile fabric by employing a layer-by-layer dip coating technique. Antifouling textile finishing was formulated by inducing the nanoencapsulation of the antifouling functional group inside the hydrophobic polymeric shell. Cotton fabric was taken as a substrate to incorporate antibacterial functionality by alternatively fabricating multilayers of antifouling polymeric formulation (APF) and polyelectrolyte solution. The surface morphology of nanoencapsulated finished textile fabric was characterized through scanning electron microscopy to confirm the uniform distribution of nanoparticles on the cotton textile fabric. Optical profilometry and atomic force microscopy studies indicated increased surface roughness in the coated textile substrate as compared to the uncoated textile. The surface thickness of the fabricated textile increased with the number of deposited bilayers on the textile substrate. Surface hydrophobicity increased with number of coating bilayers with θ values of x for single layer, up to y for 20 bilayers. The antibacterial activity of the uncoated and layer-by-layer coated finished textile was also evaluated. It was significant and exhibited a significant zone of inhibition against microbial strains Gram-positive and Gram-negative The bilayer coating exhibited water repellency, hydrophobicity, and antibacterial activity. Thus, the fabricated textile could be highly useful for many industrial and biomedical applications.
诸如纺织品表面的污垢是一项重大的健康挑战，人们一直在不断努力开发材料和工艺来克服这一问题。考虑到这一点，本研究致力于通过采用层层浸涂技术，开发用于棉纺织面料的防污功能纳米胶囊整理剂。防污纺织品整理剂是通过在疏水性聚合物壳体内诱导防污官能团的纳米封装来配制的。以棉织物为基材，通过交替制备防污聚合物配方（APF）和聚电解质溶液的多层结构来引入抗菌功能。通过扫描电子显微镜对纳米封装整理后的纺织面料的表面形态进行表征，以确认纳米颗粒在棉纺织面料上的均匀分布。光学轮廓测量和原子力显微镜研究表明，与未涂层的纺织品相比，涂层纺织品基材的表面粗糙度增加。所制备纺织品的表面厚度随着在纺织品基材上沉积的双层数增加而增加。表面疏水性随着涂层双层数的增加而增加，单层的接触角值为x，20层时高达y。还评估了未涂层和层层涂层整理后的纺织品的抗菌活性。其活性显著，对革兰氏阳性和革兰氏阴性微生物菌株均表现出明显的抑菌圈。双层涂层表现出拒水性、疏水性和抗菌活性。因此，所制备的纺织品在许多工业和生物医学应用中可能非常有用。
