Abstract
The sustainability of the environment is hampered day by day. People are more concern about environment and health including different types of goods e.g. textile goods. As a result, the researchers are interested to study environment friendly dyeing as natural dyeing. In this research bleached single jersey cotton knitted fabric (sample size: 7 inch × 7 inch) having areal density of 148 grams per square meter has been treated with some natural extract like pomagranate peel seeds, pomagranate peel bark, leaf of Thujaorientalis and leaf of Araucaria exelsa as mordanting agents. The treated samples have been dyed with natural dyes extracted from mango seed kernel (Mangiferaindica L.) and the dyeing performance was evaluated by several elementary parameters such as color strength (K/S value),color fastness to rubbing, color fastness to wash, color fastness to perspiration (acid 8 alkali). Mordanting was done at 950c temperature for 60 mins in exhaust method using lab sample dyeing machine. The dyeing was carried out at 1000c temperature for 60 mins at same machine. The results illustrated that color strength (k/s value) increases in all cases. Pomagranate peel bark treated sample shows maximum (3.52) color strength (k/s value). Different natural mordants influenced the fastness properties of the dyed samples in different way. Araucaria exelsa treated fabric exhibited higher washing resistance in comparisons to other mordants.
