Abstract

In this study, poly(ethylene terephthalate) (PET)/cationic dyeable PET (CD-PET)/viscose rayon (CV) woven fabrics were pretreated and intermediate-treated with different amounts of sodium hydroxide (NaOH) (15, 20, 25, 30, 35, 40, and 45 g/l) at different temperatures (80°C and 100°C). Afterwards, PET, CD-PET and CV parts were dyed using three-bath (separate dyeing) and two-bath (PET and CD-PET parts together and CV part separately) methods. The effects of causticisation order and processing conditions on fabric weight, pattern, and fastness properties were investigated. The best results were obtained with pre- or intermediate-causticisation realized at 80°C or 100°C using 20 g/l or 25 g/l NaOH concentrations both in three-bath and two-bath dyeings

POLİESTER/KATYONİK BOYANABİLİR POLİESTER/RAYON KUMAŞLARIN ÜÇ VE İKİ BANYOLU BOYANMASINDA ÖN VE ARA KOSTİKLEMENİN DESEN OLUŞUMU VE HASLIKLAR ÜZERİNE ETKİSİ

Abstract

Bu çalışmada poli(etilen terafitalat) (PET)/katyonik boyanabilir PET (CD-PET)/viskon (CV) karışımı dokuma kumaşlar farklı konsantrasyonlarda (15, 20, 25, 30, 35, 40 ve 45 g/l) sodyum hidroksit (NaOH) kullanılarak farklı sıcaklıklarda (80°C ve 100°C) ön ve ara işlemlere tabi tutulmuştur. Ardından PET, CD-PET ve CV üç banyolu (ayrı ayrı) ve iki banyolu yöntemle (PET ve CD-PET kısımlar beraber, CV kısım ayrı) boyanmıştır. Kostikleme işlem sırası ve şartlarının kumaş ağırlığına, desene ve haslık özelliklerine etkisi incelenmiştir. Hem üç banyoda hem de iki banyoda en iyi sonuçlar 80°C veya 100°C’ta, 20 g/l veya 25 g/l NaOH kullanılarak yapılan ön veya ara kostikleme ile elde edilmiştir
