In this study, ozone bleaching of cotton yarns
in cheese form has been examined. Thus, a more eco-friendly and economic
bleaching process compared ton conventional peroxide bleaching was aimed. Conventional
peroxide bleaching was applied as the control treatment and ozone treatment was
the tested treatment type with the time as varieable. COD values of the
bleaching bath effluents, sample whiteness values, treatment times and yarn evenness
were compared. Furtermore, yarn strength tests and SEM analysis wer performed.
Bu
çalışmada bobin formundaki pamuk ipliklerin ozon gazı ile ağartılması
incelenmiştir. Böylece klasik hidrojen peroksit ağartmasına göre daha çevre
dostu ve daha ekonomik bir proses geliştirilmesi amaçlanmıştır. Numunelere
referans işlem olarak klasik peroksit ağartması yapılmış, ozonla ağartma
denemelerinde işlem süresi değiştirilmiştir. Çalışmada atık banyoların KOİ
yükleri, beyazlık değerleri, ozonlama süreleri ve iplik düzgünsüzlükleri
karşılaştırılmıştır. Ayrıca ipliklerin SEM analizi yapılarak lif yüzeyindeki
etki izlenmiş ve ipliklere mukavemet testleri uygulanmıştır.
