Polypropylene (PP) fiber is considered to be the cheapest synthetic fiber. Itposseses some precious characteristics, such as high strength and light weight, high abrasion resistance and high covering power. However, polypropylene fiber does not absorb water, which limits its apparel application. Cotton fiber absorbs water but its crease and abrasion resistance are not as high as
that of PP fiber. A polypropylene and cotton blended yarn for apparel application is investigated which may possess the characteristics of both kinds of fiber. The open-end spinning technology of a polypropylene/- cotton blendedyarn has been studied in this investigation. The main objective of this study is to investigate the three main facxtors: rotor speed, rotor diameter, and twist multiplier of open-end spinning, as well as their effects on yarn qualities and the running condition of the open-end spinningprocess. The response variables for yarn qualities are break factor, CV % for yarn evenness, thin places, thick places and nep count. The response variable for running condition is end-breakage. The experimental results indicated that there is apossibitity of producing polypropylene/cotton blended yarn at a high production rate with low cost by open-end spihning.

Polipropilen (PP) lifi, en ucuz sentetik lif olarak kabul edilmektedir. Yuksek dayanzm ve dugiik gramaj, yiiksek agznma direnci ve yuksek ortuciiliik gibi degerli baa ozellikleri vardzr. Bununla birlikte polipropiZen lifi suyu absorbe etmez; bu da giyim alanznda kullanzmzna kzsztlamalar getirir. Pamuk lifi suyu absorbe eder; ancak burugma ve agznma direnci, PP lifi kadar yuksek degildir. Giyim alanzndaki kullanzmz icin, her iki lif tipinin ozelliklerine sahip olabilen polipropilen ve pamuk karzgzmz bir iplik aragtzrzlmaktadzr.
