Abstract:

Polyester knitted fabrics are conventionally dyed with a process consisting alkali reduction, high temperature and high pressure exhaust dyeing, reduction cleaning, and washing. These steps are taking place individually, consuming more time and energy. To solve this problem in this research, polyester knitted fabrics were dyed with alkali-resistant disperse dyes under an alkali condition called onebath-one-step exhaust dyeing and alkali reduction process. Influences of the dosage of sodium hydroxide, process temperature and duration on the properties of polyester fabrics using the one-bath-one-step process were investigated. An optimized process was obtained as follows: sodium hydroxide 10 g/ L, temperature of 130 ℃ and duration of 50 min. It was found that compared with the ones obtained by conventional dyeing process, polyester fabrics treated with the one-bath-one-step process exhibited dyeing depth values 10% higher than the conventional dyeing process. This means that in order to achieve the same color, the use of one-bath-one-step process could save effectively the dosage of dyes. The dyed polyester fabrics treated with the one-bath-one-step process were stable in color and demonstrated excellent colorfastness.
