Abstract

Abstract:

This innovative method aims to impart enhanced coloristic properties including deeper shade, high color fastness, and a distinctive soft handle as well as valuable functional attributes such as antibacterial activity, ultraviolet (UV) protection, and long-lasting aromatic scent. Moreover, the formulation demonstrated remarkable paste stability, maintaining its performance over extended storage periods. Experimental investigations confirmed that the treated samples exhibited excellent photochromic behavior, vibrant color change under UV exposure, and superior durability against washing and rubbing. Functional analyses revealed notable antibacterial efficacy and effective UV-blocking capacity, in addition to sensory appeal due to the retained fragrance. Scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) were employed to examine surface morphology and identify functional groups responsible for the observed properties. The results highlight the potential of integrating photochromic dyes and natural oils in textile finishing for innovative, eco-friendly applications with sensory and protective functionalities.
