 Cotton fabrics were modified through an oxidation with hydrogen peroxide followed by chitosan to improve their diability toward cochineal natural dye, and studies were conducted to select the best modification process and assess their diability. The scanning electron micrograph showed chitosan was deposited on the surface of cotton fibers, while infrared spectroscopy revealed interaction between chitosan and cellulose. Thermal gravity analysis showed little effect on thermal stability, and treating with 15G L chitosan and baking at 130 degrees Celsius offered higher cochineal adsorption. Dyeing with increased time and temperature resulted in higher dye uptake, and the ratio of ethanol and water affected solution polarity, with a proportion of 9 to 1 reaching maximum cochineal adsorption. pH value had complex effects on Ks value, with pH 7 yielding the highest colour strength. Dyeing kinetics curves indicated that increasing dyeing temperature increased the diffusion coefficient and decreased half dyeing time. The washing and rubbing fastness of treated cotton fabrics were improved and rated above grade 3. This article was authored by Guayshanku, Kandishu, and Mofasa Hub Choudhury.
