Abstract
The main objective of the present study was to meticulously investigate an inclusive set of physicochemical properties of pre-wetted cotton yarns and optimize the snailase treatment for raw cotton yarns. Based on single factor design, effects of snailase treatment on the removal percentage of pectins and cotton waxes, wettability, and weight loss were studied in different snailase concentrations and the optimal concentration range was obtained. The Box-Behnken design was employed to determine the optimal condition of snailase treatment for achieving the maximum wettability of cotton yarns. The maximum wettability was obtained when treated at 16.90 g/L of snailase concentration at 56.85 °C for 27.77 s. The theoretical and observed values were in reasonably good agreement, and the deviation was less than 1%. Results revealed that snailase had a positive effect on pectin and wax removal, had an obvious impact on weight loss, and significantly enhanced the wettability of raw cotton yarns.
