The textile industry is currently experiencing a paradigm shift, driven by an increasing demand for sustainability and environmentally friendly practices. As consumers become more conscious about the ecological impact of their purchasing decisions, there is a growing emphasis on materials that fulfill both aesthetic and functional needs. Among these materials, wool stands out due to its unique qualities, including breathability, moisture management, and thermal insulation, as well as its long-standing reputation as an eco-friendly fiber. However, traditional dyeing and printing processes employed in the industry often rely on hazardous chemicals and involve excessive water usage, which poses significant environmental challenges. This research aims to address these pressing issues by developing sustainable inkjet printing inks that enhance the aesthetic appeal of wool and wool blend fabrics. We formulated these inks using biodegradable biopolymer carboxymethyl cellulose (CMC), combined with various other constituents, specifically tailored for effective printing on wool substrates. The study involved the preparation of both acid and pigment inks, followed by a comprehensive evaluation of their physical and performance properties compared to commercially available inks. The findings highlighted that the acid inks achieved a measured viscosity of 7.47 cSt, while the pigment inks recorded a viscosity of 8.24 cSt, indicating their suitability for various printing applications. Furthermore, the formulated inks demonstrated impressive UV resistance and biodegradability, affirming their eco-friendly nature and potential for reducing the environmental footprint commonly associated with textile printing. This innovative approach to digital fabric printing not only enhances the visual appeal and absorbency of woolen textiles but also represents a significant stride towards sustainable practices in the textile industry.
