Abstract

In this study, at different ratios mordanted with iron (II) sulfate (FeSO₄.7H₂O) and potassium aluminum sulfate [KAl(SO₄)₂12.H₂O] cotton fabrics were dyed gall oak (Quercus infectoria Olivier). Laser radiation firstly was used on raw cotton fabrics and secondly, cotton fabrics with different ratios of metallic mordanted and dyed with gall oak were irradiated to examine the laser radiation effects on textile color using several combinations of the two main laser parameters namely the number of pulses and energy density at 1064 nm. Colorimetric analysis of the cotton fabrics was measured by CIEL*a*b* spectrophotometer and examined surface alterations. Morphological analysis was performed using optical microscopy. The color coordinates and fastness values of washing rubbing, and light were investigated by comparing them with each other.

Keywords

Mazı meşesi (quercus ınfectorıa olıvıer) ile boyanmış Pamuklu kumaşlarda lazer radyasyon uygulamaları

Abstract

Bu çalışmada, farklı oranlarda potasyum alüminyum sülfat [KAl(SO₄)₂12.H₂O] ve demir sülfat (FeSO₄.7H₂O) metal tuzlarıyla mordanlanan pamuklu kumaşlara mazı gomalağı bitkisiyle (Quercus infectoria Olivier) doğal boyama işlemi yapılmıştır. 1064 nm’de lazer radyasyonun farklı puls sayısı ve enerji yoğunluğu kombinasyonları kullanılarak ilk olarak ham pamuklu kumaşlarda ve ikinci olarak, farklı oranlarda metalik mordanlanmış ve mazı gomalağı ile boyanmış pamuklu kumaşlarda ışınlama yapılarak renk üzerindeki etkileri incelenmiştir. Pamuklu kumaşların kolorimetrik analizi CIEL*a*b* spektrofotometre ile ölçülmüş ve pamuklu kumaşların yüzey değişimleri incelenmiştir. Morfolojik incelemelerde optik mikroskop kullanılmıştır. Boyanmış örneklerin yıkama, sürtme, ışık haslık değerleri ve renk koordinatları karşılaştırılmıştır.
