To improve faslness values is very hard and difficult work after finishing all dyeing process for blended fabrics which have different dyeing and washing processes. In study, different extra washing experiments have been applied to Polyester/Viscone/Elastane blended fabric for improving its fastness values. At the end of experiments, while fastness values have been wanted to improve, it also has been aimed not to change final hue of fabric. Therefore, the samples got by experiments have been applied both spectrofotometric colour measurement and different fastness tests. To determine fastness performance of samples, washing fastness (A2S, B2S, C2S, D2S) rubbing fastness, perspiration fastness (acidic-alkaline), water fastness tesls, dry-cleaning fastness, which are classified as usage fastness tests, have been applied and their results have been detaily investigated.
