Abstract
Four different blended fabrics which comprised polyester/viscose (50/50), wool/cotton (50/50), wool/cotton (30/70) and cotton/linen (50/50) were subject to burn-out printing style using different agents. The latter comprised different concentrations of aluminum sulphate, sodium mono hydrogen phosphate, aluminum potassium sulphate, sodium hydroxide, tartaric acid, oxalic acid and citric acid. The burn-out printed blends were subject to dyeing using an eco-friendly natural dye, namely madder. The results obtained were evaluated via measuring the percentage (%) loss in weight, the K/S of the colored samples as well as the overall color fastness properties. The results revealed that the loss in weight was dependent on (a) the nature of the blend components, (b) the nature of the burn-out reagent, and (c) the concentration of the used reagent. The dyed burn-out areas were found to have a higher or lesser K/S than that of the ground shade. Hence, different color tones could be obtained which reflect attractive and beauty features. The overall color fastness properties for the blended fabrics printed before and after the burn-out treatment were nearly identical.
