Abstract
In the present work, novel synthesis of subphthalocyanine chlorides was performed and used for dyeing polyester and wool fabrics. The chemical structure of subphthalocyanine was confirmed and evaluated using 1H NMR, FTIR, element analysis and mass spectra. The morphological properties of fabrics before and after dyeing were studied using SEM and EDX measurements. The Color strength (K/S) measurements of the dyed fabrics and their color fastness to rubbing, washing, and perspiration, and light were investigated. Moreover, the UV protection measurement (UVP) was tested for the dyed fabrics. The results indicated that the dyed fabrics showed remarkable higher K/S value than un-dyed fabrics. The dyed of both polyester and wool fabrics showed improved UVP as 16.2 and 49.1 values compered to un-dyed fabrics 5.5 and 22.2, respectively. The results also indicated that, the fastness properties of dyed wool fabric and polyester have good to very good to perspiration rubbing, washing, light and rubbing fastness. This work provides simple and efficient process for dyeing of polyester and wool fabrics for smart functional fabrics.
