Abstract

Tek katlı iplikler, tüylülük, mukavemet, kopma uzaması, aşınma direnci gibi bazı iplik ve kumaş özelliklerini iyileştirmek için katlanmaktadır. Bu çalışmada, katlı ipliklerin iplik tüylülüğünü azaltmak için yeni bir metot önerilmektedir. Modifiye katlama metodu, klasik büküm makinesinde bir hava düzesi ve basınçlı havanın kullanılmasından oluşmaktadır. Basınçlı hava bir hava düzesine verilmekte ve tek katlı iplikler düze içerisinden geçirilmektedir. Çalışmada, S- ve Z- bükümlü tek katlı iplikler farklı katlama büküm değerlerinde ve basınçlı hava özelliklerinde klasik ve modifiye katlama metodu ile katlanmışlardır. Elde edilen sonuçlar, sunulan metodun katlama prosesi sırasında iplik tüylülüğünde ekstra bir iyileşme elde edilmesi ve aynı zamanda verimlilikte artış sağlanması konularında yeni bir kapı açacağını göstermiştir. Literatürde, hava düzesi ile katlama prosesinin bu tarzda birleştirilmesine yönelik herhangi bir deneme bulunmamaktadır. Bu nedenle, modifiye katlama metodu iplik tüylülüğündeki iyileşme açısından yenilikçi bir katlama prosesi olarak değerlendirilebilir

A STUDY FOR THE MODIFICATION OF A YARN TWISTING MACHINE WITH AN AIR NOZZLE

Abstract

Single yarns are plied to improve some of the yarn and fabric properties such as hairiness, strength, elongation, evenness and abrasion resistance. Present work proposed a new method for the reduction of the plied yarn hairiness. The modified plying method employs an air nozzle and compressed air on a classical twisting machine. The air was fed into an air nozzle and single yarns were passed into the air nozzle. In the work, single yarns having S- and Z-twist direction were plied with classical and modified plying methods at different ply twist levels and airflow properties. The results indicated that presented method may open a new avenue to achieve an extra reduction in yarn hairiness and also an increase in productivity during the plying process. In literature, there were not any trials to incorporate the air nozzle and plying process in this manner. Therefore, modified method can be considered as an innovative plying process regarding with the improvement in yarn hairiness
