REAKTİF BOYARMADDELERLE BOYANMIŞ PAMUKLU KUMAŞLARIN RENK ÖZELLİKLERİNİN CIELAB VE HUNTER SİSTEMLERİ KULLANILARAK FARKLI AYDINLATICILAR ALTINDA DEĞERLENDİRİLMESİ

Bu çalışmada reaktif boyarmaddeler ile boyanmış pamuklu kumaşların renk özellikleri D65, A ve F11 aydınlatıcıları altında CIELAB ve Hunter sistemleri ile hesaplanarak değerlendirilmiştir. Kumaş numuneleri dört farklı reaktif boyarmadde (siyah, sarı, kırmızı ve mavi) ile on ayrı boyama konsantrasyonunda boyanmış ve boyanmış numunelerin renk koordinatları bir reflektans spektrofotometresi ile ölçülmüştür. Sonuç boyamaların renk koordinatları ve renk farklılıkları CIELAB ve Hunter sistemlerine göre hesaplanmış ve elde edilen sonuçlar boyamaların renkleri ile ilişkili olarak tartışılmıştır. CIELAB ve Hunter sistemlerine göre hesaplanan renk sonuçlarının elde edilen renklerin farklılıklarına göre hassas olduğu bulunmuştur. Renk koordinatları Hunter sistemine göre hesaplandığında siyah, sarı, kırmızı ve mavi renklerin aydınlatıcı seçimine hassas olduğu görülmüştür. Hesaplanan en yüksek renk koordinatları farkı sarı renkte elde edilmiştir

ASSESSMENT OF COLOUR PROPERTIES OF REACTIVE DYED COTTON FABRICS UNDER DIFFERENT ILLUMINANTS BY USING CIELAB AND HUNTER SYSTEMS

Öz

This paper focuses on the assessment of colour properties of reactive dyed cotton fabrics at four different shades under the illuminants of D65, A and F11 by using CIELAB and Hunter systems in computing. The fabric samples were dyed with four reactive dyes (black, yellow, red and navy) at ten different dyeing concentrations (% owf) and the colour coordinates of the dyed samples were measured by a reflectance spectrophotometer. Colour coordinates and colour differences of the resultant dyeings were calculated according to CIELAB and Hunter systems and the results were discussed in accordance with the shades obtained. The colour results which were calculated according to CIELAB and Hunter systems were found sensitive to the shade variations. Black, yellow, red, and navy shades were found sensitive to illuminant choice when the colour coordinates were calculated according to the Hunter system. The highest differences between the calculated colour coordinates were obtained at yellow shade
