Abstract

In this research, Chitosan-Cyanuric chloride hybrid (Ch-Cy) was applied onto wool fabric. The effect of significant factors such as Ch-Cy concentration, temperature and pH were evaluated on the grafting process. Scanning Electron Microscopy (SEM) and Differential Scanning Colorimetry (DSC) revealed the finishing of Ch-Cy onto wool fabric was carried out succesfully. The modified fabric was dyed with Reactive Red 195 and according to obtained R and K/S values of colored fabrics, the optimum values for operating variables determined which were CCh-Cy= 15% (owf), T=70 °C and pH=4-5. The results showed that the Ch-Cy improved the dyeing ability of wool and fastness properties of dyed modified fabrics indicated no significant differences compared to the untreated samples.
