Abstract

Pamuklu kumaşların buruşmazlık bitim işlemleri özellikle son 20 yılda büyük ilgi çekmektedir. Bu bitim işlemlerinde kullanılan Nmetilol esaslı bileşiklerin, zehirli, alerji yapan ve karserojen bir kimyasal olan formaldehitin salınmasına neden olduğu bilinmektedir. Bu durum tekstil amaçlı kullanımlarda, araştırmacıları yeni arayışlara itmiştir. Bunlardan birisi de çevreye daha az formaldehit salınımı yapan bileşikler kullanmaktır. Bu çalışmada, buruşmazlık bitim işleminde çevreye düşük formaldehit yayan kimyasallar kullanılmıştır. Çalışma kapsamında; yarım ağartılmış, ağartılmış & optik beyazlatılmış ve ağartılmış & merserize edilmiş & optik beyazlatılmış pamuklu kumaşlara piyasada yaygın olarak kullanılan bir buruşmazlık apresi uygulanmış ve apreli kumaşların buruşmazlık açısı, kopma mukavemeti ve CIE beyazlık indeksi değerleri ölçülmüştür. Ayrıca, buruşmazlık apresinin yaygın olarak uygulandığı gömleklik kumaşlara öncelikle ağartma yapılmış, farklı flotte oranı ile kurutma ve kondenzasyon sıcaklıklarının buruşmazlık açısı, kopma mukavemeti ve CIE beyazlık indeksi değerlerine etkileri incelenmiştir

EFFECTS OF ALTERNATIVE PRE-TREATMENTS ON PERFORMANCE OF DURABLE PRESS FINISHED FABRIC

Abstract

Wrinkle recovery of cotton fabrics has attracted much attention, especially for the last 20 years. It is known that N-methylol based chemicals used in these applications cause release of formaldehyde which is a toxic, allergenic and carcinogenic chemical. This has caused researchers to focus on alternative approaches. One of them is using compounds that release lower amount of formaldehyde to the environment. In this study, chemicals with low formaldehyde-release potential are applied on half-bleached, bleached, and bleached & mercerized & optical brightening cotton fabrics, and their wrinkle recovery angles, breaking strengths, and CIE whiteness index values are measured. Moreover, shirting fabrics which are the most popular subjects of durable press finishes, are bleached and then treated with durable press finish in varying liquor ratios, and drying and curing temperatures, and their resulting wrinkle recovery angle, breaking strength and CIE whiteness index values are measured
