Son yıllarda, teknolojinin gelişmesine paralel olarak üretim sürecinde var olan konvansiyonel yöntemlerin yetersiz kaldığı

In recent years, it is observed that the conventional methods in the production process are insufficient with parallel tothe development of technology. It is an unavoidable solution to produce high-value-added products in order to increase Turkey’sexport share. One of the solutions in yarn production is to manufacture functional yarns by using different raw materials. In this study,dual core-spun yarns were produced by a modified ring spinning system that allows the feeding of the two different core materialssimultaneously. Within the scope of the study, dual core-spun yarns with two different yarn count (Ne 12/1 and 18/1) were producedusing three different sheath fibers (100% cotton, 60/40% cotton/polyester, and 100% polyester) and core materials (PET/PTT bicomponentfilament + elastane, Polybutylene Terephthalate (PBT)+elastane, and Polyethylene Terephthalate (PET)+elastane) at thesame production conditions. In order to determine the effects of yarn count, sheath fiber and core material on yarn tenacity andelongation, yarn unevenness, imperfection and hairiness properties, analysis of variance (ANOVA) was conducted using SPSSpackage program at 95% confidence interval.
