Enhancing antibacterial and water-repellent properties for the production of high-performance fabrics in home textiles

Abstract

In this research, we aimed to enhance the antibacterial activity and water repellency functionalities of single-layer 100% cotton fabrics on both the face and back sides, utilizing conventional methods. Unlike conventional approaches that often rely on lamination or coating techniques to imbue fabric surfaces with distinct properties, our study pursued a cost-effective strategy using traditional textile finishing methods. By integrating double functionality into cotton fabric, we aimed to circumvent the need for additional equipment and high initial costs associated with other techniques. To achieve this, we improved the antibacterial activity of the fabrics through the incorporation of silver ions in the pad-dry process. Simultaneously, water repellency functionality was introduced through a printing application, where the printing paste, devoid of dyestuff, was combined with functional agents and applied using rotary printing to the fabric's backside. Following these finishing applications, we conducted comprehensive tests encompassing washing durability, antibacterial efficacy, water repellency, mechanical strength, and fastness properties of the multifunctional fabrics. Characterization tests, including Fourier transform infrared attenuated total reflectance (FTIR-ATR) and scanning electron microscope analyses (SEM-EDX), were performed. The outcome of our study showcased the successful enhancement of double-functional cotton fabric, featuring water repellency and antibacterial efficiency on distinct sides. Furthermore, the results indicated that these functionalities endured up to 20 washing cycles, with fastness and performance tests consistently achieving peak levels.
