| description | Bast fiber dyeing process is common practice as the value addition of most bast fibers demanded for various commercial and household applications. In this research work, kusha fiber (extracted previously) was subjected to dyeing using direct, reactive, vat and cationic dyes for the first time. Dyeing process was perfrmed using concentrations 0.5%, 1%, & 3% (W/W) dye to fiber with MLR 1:20. After dyeing process, performance of dyed fiber and tensile tests were conducted. The results revealed that K/S value of all dyed kusha fiber samples increases as the concentration of dyes applied increases. The dyed fibers color fastness to washing was found good both in dry and wet rubbing fastness. Reactive dyed samples have shown good rubbing fatness performance over the others. Regarding light fastness, the result shows there was good performance for all samples according to blue wool light fastness standard that exceeds 6. The tensile strength and elongation of dyed samples showed slight decrement both in vat and direct dyed samples; whereas, considerable decrement was observed both in reactive and basic dyed samples due to formation of covalent bond and acid processing medium. |
