AN INVESTIGATION ON THE EFFECTS OF PLY AND SINGLE TWISTS ON STRENGTH, HAIRINESS AND ABRASION RESISTANCE PROPERTIES OF TWO-PLY COTTON RING-SPUN YARNS

Calismada; cift kat ve tek kat bukumunun, uc farkli numaraya sahip cift katli ipliklerin mukavemet, tuyluluk ve asinma direnci uzerindeki etkileri incelenmistir. Katli bukum miktarinin katli ipliklerin mukavemeti uzerindeki etkisinin, bukumun tek katli ipliklerdeki etkisine benzer oldugu, tek kat bukumundeki artisin katli iplik mukavemetinde dusmeye sebep oldugu gorulmustur. Kopma uzamasi degerleriyle ilgili olarak; gerek katli bukum, gerekse tek kat bukumu artisinin, katli ipliklerin kopma uzamasi degerlerinde artisa yol actigi gorulmustur. Tuyluluk sonuclariyla ilgili olarak; gerek katli bukum, gerekse tek kat bukumunun ipliklerin tuyluluk degerleri uzerinde etkili oldugu ve bukum artisiyla birlikte tuyluluk degerlerinde azalma oldugu gorulmustur. Bununla beraber; katli bukum miktarinin tuyluluk degerleri uzerinde daha etkili oldugu gorulmustur. Gerek ince ipliklerde, gerekse kalin ipliklerde, cift katli bukum miktari arttikca asinma direnci artmaktadir. Ince ipliklerde, tek kat bukumunun asinma direnci uzerindeki etkisi gorulmezken, kalin ipliklerde, tek kat bukumunun dusuk olmasinin asinma direncini arttirdigi gorulmustur
