Abstract

Çalışmada aynı harmandan alınmış %100 pamuk kullanılarak, farklı iplik numaralarında ring iplikleri üretilmiştir. İplikler farklı yoğunluklarda sarılarak, boyama bobinleri oluşturulmuştur. Bobinler % 4 konsantrasyonda, C.I. Reactive Black 5 boyarmaddesiyle boyanmıştır. İplik numarası, bobin yoğunluğu, pompa devri, sirkülasyon süresi (iç-dış) ve sıcaklık yükselmesi, boyamanın düzgünlüğüne etki edebilecek parametreler olarak seçilmiştir. Lineer çoklu regresyon modelleri kullanılarak, boyama farkları ve seçilmiş parametreler arasındaki ilişki tespit edilmeye çalışılmıştır. İstatistiksel çalışma sonucunda, yüksek sayılabilecek düzeltilmiş determinasyon katsayısı (adjusted R2) değerlerine ulaşılmıştır. Ayrıca varyans analizi sonucunda bulunan eşitliklerin 0,01 (%99) anlamlılık seviyesinde anlamlı olduğu bulunmuştur

EFFECT OF SELECTED PARAMETERS ON COLOR DIFFERENCE AT DYEING OF COTTON PACKAGES WOUND FROM RING SPUN YARNS

Abstract

In this study, %100 combed ring yarns with different yarn counts, which were used from the same raw material blend were produced and wound to different package densities. Bobbins were dyed with C.I. Reactive Black 5 (4 %). Here, the yarn count, package density, pump rotation, circulation time (in-out) and gradient of temperature are selecting parameters that can affect levelness of dyeing. The color difference (DE) of the dyed yarn was measured in two different zones of each packages internal and external zone to determine the levelness of dyeing. Linear multiple regression methods were used for the estimation of relation between the parameters and color differences. In the result of statistical study, goodness of adjusted R2 (coefficient of multiple determination) values were observed. Furthermore, analysis of variance showed that equations were significant at significance level (p<0.01)
