ABSTRACT

The advantage of enzyme scouring over alkali scouring is that the enzymatic process can be carried in a neutral pH, resulting in less damage on the fibers and a drastic reduction of wastewater. Since the pH of scouring bath is neutral, dyeing can be carried in the same bath. Four different types of scouring and dyeing in a single-bath were performed in this work: continuous scouring and dyeing in one-bath I and II, simultaneous scouring and dyeing in one-bath I and II. The difference between process I and II is the existence of an after-treatment process in the scouring. Dyeing was performed with three major colors(red, blue, yellow) and black to investigate the dye-ability. The absorbency of scoured and dyed fabrics was measured using gravimetric absorbency testing system. The fabric weight loss was measured after the treatment. Although the color depth for the three major colored fabrics treated in a single-bath was lower than the fabric scoured and dyed separately, the fabrics dyed with black did not show much difference. In addition, the absorbency of fabric treated in a single-bath was higher than the fabric treated separately.
