Synthesis of castor oil/poly (N-vinyl-2-pyrrolidone)/ammonium persulfate hybrids emulsion as textile softeners

Abstract

AbstractTwo castor oil / poly (N-vinyl-2-pyrrolidone) / ammonium persulfate (CAO/PVP/APS) hybrids were synthesized via reaction of castor oil with PVP of molecular weights 40000 and 1300000 Dalton in presence of APS as an initiator. The optimum reaction conditions are: PVP/CAO weight ratio, 15%; PVP concentration, 60%; APS conc., 4% (based on weight of CAO); reaction temperature, 80 °C; reaction time, 60 min. The synthesized CAO/PVP/APS hybrids were characterized via FTIR analysis whereas their emulsions particle sizes were determined using TEM analysis. Incorporation of either of the aforementioned hybrids emulsions in the easy care finishing formulations of cotton fabric results in promoting of fabric softness, tensile strength, flexibility, and antibacterial activities of treated fabric along with reducing fabric wettabiliy and resiliency. Inclusion of Ag-NPs in the aforementioned finishing bath significantly improves extent of the antibacterial activities of treated fabric. The treated fabric morphology was examined using SEM as well as EDX analysis.
