چکیده
|
In this study, poly(ethylene terephthalate) (pet)/cationic dyeable pet (cd-pet)/viscose rayon (cv) woven fabrics were pretreated and intermediate-treated with different amounts of sodium hydroxide (naoh) (15, 20, 25, 30, 35, 40, and 45 g/l) at different temperatures (80°c and 100°c). afterwards, pet, cd-pet and cv parts were dyed using three-bath (separate dyeing) and two-bath (pet and cd-pet parts together and cv part separately) methods. the effects of causticisation order and processing conditions on fabric weight, pattern, and fastness properties were investigated. the best results were obtained with pre- or intermediate-causticisation realized at 80°c or 100°c using 20 g/l or 25 g/l naoh concentrations both in three-bath and two-bath dyeings.
