【 摘 要 】

At present, customers are more conscious about the quality of clothing items. As a result, it becomes more challenging for the manufacturers to maintain the consistent dyeing quality. Unlevelness is generally unaccepted in commercial dyeing, except some cases such as stone-washed, acid-washed or pigment-dyed textiles. The aim of the study was to evaluate the color levelness quality of fabric dyed with vegetable dyes. For this purpose, dyeing was carried out on silk fabric with the aqueous extracts of mango, guava and henna leaves. Then the levelness of colored fabric was evaluated by spectrophotometric measurements in terms of color difference, ∆E value. It was concluded that unmordanted dyed samples have better color levelness quality than the mordanted ones. The unmordanted samples dyed with mango and guava leaves extracts showed excellent levelness quality while the unmordanted ones dyed with henna leaves extracts showed good levelness quality. On the other hand, the mordanted dyed samples showed good leveling quality for the three vegetable dyes except ferrous sulphate mordanted sample dyed with henna leaves extract. Again, among the mardanted samples the levelness quality was comparatively better in case of alum mordanted dyed samples and the average ΔE value was increased gradually when moved from alum to tin and finally to ferrous sulphate.
