    Effect of different dyeing conditions on color properties of avitera se reactive dyed cotton woven fabric
    (UMT, Lhr, 2015-11-03) JAHANZEB MURTAZA; Shahid Kamran
    In this research study, plain cotton woven fabric is treated with Avitera SE reactive dye by using exhaust method. The color values of dyed cotton fabric samples are measured by using SF 650X Spectra flash spectrophotometer. The physico-chemical properties (rubbing and washing fastness) are also investigated by using Crock Meter (21P00-02) and landro meter.. It is concluded that with increasing the dyeing temperature of reactive dyeing the value of color strength (K/S) also increases. It is observed that the washing fastness and rubbing fastness values of reactive dyed cotton fabric decrease by increasing the amount of dye concentration and salt concentration. It is found that the washing fastness and rubbing fastness values of reactive dyed cotton fabric slight improvement achieved by increasing the amount of alkali, time and temperature
