Gamma radiations induced improvement in dyeing properties and colorfastness of cotton fabrics dyed with chicken gizzard leaves extracts

Cotton fabric and chicken gizzard leaves powder were treated with different absorbed doses of 5, 10, 15, 20 and 25kGy using Cs-137 gamma irradiator. Effects of different mordants on dyeing of un-irradiated and irradiated cotton fabrics were investigated in the CIE Lab system using Spectraflash SF650...

Description
Summary:Cotton fabric and chicken gizzard leaves powder were treated with different absorbed doses of 5, 10, 15, 20 and 25kGy using Cs-137 gamma irradiator. Effects of different mordants on dyeing of un-irradiated and irradiated cotton fabrics were investigated in the CIE Lab system using Spectraflash SF650. Methods suggested by International Standard Organization (ISO) were followed throughout the study period. The results indicated that color strength of cotton fabric was significantly improved by the gamma ray treatment. Absorbed dose of 10kGy was proved to be most effective in improving cotton dyeing properties compared with other levels of gamma radiation used in the study. The optimum temperature for dyeing was 60°C with the time duration of 60min using 4g/L of electrolyte with alkali solubilized extract of chicken gizzard. Furthermore, 4% of iron (Fe) as pre-mordant and 1% of tannic acid (TA) as post-mordant proved to be more effective in enhancing the color fastness properties of irradiated cotton fabric. •The optimum absorbed dose obtained for surface modification of cotton (RC) is 10kGy.•The optimum absorbed dose for extraction of colorant in alkaline media from Iresine powder (RP) is 10kGy .•Optimum dying conditions: 60°C , 60min, 4g/L of salt, and pH 8.•Optimum pre-mordants 5% iron (Fe) and 1% Tannic Acid TA as post-mordant.•At these optimum conditions, color strength and fastness properties are enhanced.
