Gamma Irradiation Effects on Natural Dyeing
Performances of Wool Fabrics

Abstract:

The objective of this study was to improve the performance of natural dyeing on fabrics made of 100% wool by gamma pre-irradiation technique. For this purpose, the fabrics were subjected to irradiation with different doses in the range of 5 kGy - 40 kGy using a gamma irradiator Co-60 and then subjected to natural dyeing by discountinous exhaustion processes. Due to the lack of colour reproducibility in natural dyeing a natural commercial dye has been used - Itodye Nat Pomegranate. The mordanting of pre-irradiated and naturally dyed fabrics has been performed using iron alum. To establish the effectiveness of gamma pre-irradiation treatment on natural dyeing measurements for colour and color fastness to washing, light, wet and dry rubbing, acid and alkaline perspiration were performed. The results obtained were analyzed in comparison with those recorded for non-irradiated and dyed fabrics. The investigation of the effect of gamma radiation on textile materials dyed was carried out by assessing the physico-chemical, physico-mechanical and surface characteristics of the dyed textile materials. Infrared spectroscopy was used to monitor chemical and structural changes in proteinic fibers induced by gamma irradiation and dyeing process. Surface modifications of wool fibers, as an effect of gamma radiation treatment and natural dyeing processes were studied by electron microscopy. Key words: gamma irradiation, natural dyeing, wool fabrics
