ABSTRACT

In this study, the effect of microwave which can increase temperature rapidly on polyester alkaline dyeing was investigated. The final K/S values of polyester fabrics dyed by microwave lower than those of atmospheric dyeing because of the evaporation loss of dyeing solution. If the dyeing time makes longer as much as that in atmospheric dyeing, the K/S values of polyester fabrics dyed under microwave were similar to those of atmospheric dyeing. The K/S values of polyester fabrics dyed in pH 9.5 were higher than those in pH 5.5 in case of aliphatic carriers. The K/S values of organic reagent pretreated polyester fabrics dyed by use of aromatic carriers were not higher than those of non-treated polyester fabrics. But the K/S values of polyester fabrics dyed by use of aliphatic carriers were higher than those of non-treated polyester fabrics. The tensile strength were decreased with increasing of dyebath pH because the polyester fabrics were easily decomposed by high alkali.
