SELÜLOZİK DOKUMA KUMAŞLARDA KOSTİKLEMENİN BURUŞMAZLIK ÖZELLİĞİNE ETKİSİ

Selüloz ve rejenere selüloz lifleri, günümüzde dünyada çok yaygın bir şekilde kullanılmaktadır. Bu liflerin birçok avantajı olmasına rağmen kolay bir şekilde buruşmaktadırlar. Performans arttırıcı terbiye işlemleri sayesinde buruşma özelliği elimine edilmektedir. Bu çalışmada; buruşmazlık bitim işlemlerinden önce yapılan kostikleme işleminin kumaşların buruşmazlık, kopma mukavemeti ve aşınma dayanımı özellikleri üzerine olan etkisinin incelenmesi amaçlanmıştır. Kostikleme işlemleri; %100 merserize pamuk, %100 merserize yapılmamış pamuk, %100 keten ve %100 viskon dokuma kumaşlara farklı kostik konsantrasyonlarında uygulanmıştır. Kumaş tipi, kostik konsantrasyonu ve çapraz bağlayıcı konsantrasyonu parametreleri ayrı ayrı değerlendirilmiştir. Elde edilen sonuçlar tartışılmıştır

EFFECTS OF CAUSTICIZING ON CREASE RESISTANCE OF CELLULOSIC WOVEN FABRICS

Cellulose and regenerated cellulose fibers are used widely in the world recently. In spite of many advantages of cellulosic fibers, they can wrinkle easily. Because of the performance enhancing finishes, the wrinkle property can be eliminated. In this study, it was aimed to investigate the effect of causticizing treatment before the crease resistance finishing on the crease resistance, breaking strength and abrasion resistance properties of the fabrics. The causticizing processes were applied to 100% mercerized cotton, 100% unmercerized cotton, 100% linen, and 100% viscose woven fabrics at different caustic-soda concentration. The fabric type, the causticsoda concentration and the concentration of crosslinking agent parameters were evaluated independently. The obtained results were discussed
