Effect of Musa acuminata SAP on Whiteness Index and Physical Properties of Cotton Finished Fabrics

Thirty-six samples of woven fabric were finished with Musa acuminata SAP in three different concentrations, viz., 50%, 75%, and 100% were applied on cotton fabrics using padding mangle at four different temperatures, viz., room temperature, 50°C, 75°C, and 100°C and also with three different process timings, viz., 20 min, 40 min, and 60 min, respectively. The finished fabrics have been analyzed on the whiteness and yellow index properties. It has been observed that the fabric finished with a 50% concentration of Musa acuminata SAP with 50°C for a prolonged time of processing shows a lesser yellow index and higher whiteness index value followed by the 100% and 75% concentration of SAP. The finished optimized fabric samples have been evaluated on the physical properties of fabric such as tensile strength, tear strength, pilling, drape coefficient, and stiffness of the fabric. It has been found that the fabric finished with a 50% concentration of Musa acuminata SAP with the lowest temperature at least processing time has better performance in the physical properties of the fabric when compared to the highest concentration of Musa acuminata SAP with the highest temperature at highest process timing.
