The environmental load problem of the cotton fiber such as amount of water and pesticides used in the agricultural sector, the main raw material of the textile and apparel industry, obligates the extension of the fiber's life cycle. In order to ensure the sustainability of resources, efficient use of natural supplies and evaluation of recyclable wastes are required. However information lacking is the one of barriers in recycling and processing of cotton. In this study, open-end rotor yarns (OE-Rotor) were spun from the blends of recycled cotton fibers obtained from pre-consumer cotton products (r-CO) and the virgin cotton (C) fibers with 50/50 % ratios. The effects of production parameters (rotor type, navel type and torque type) on yarn properties were examined. According to the results the effect of the production parameters on all measured yarn properties except tenacity values, is statistically significant. It was concluded that %50/50 r-CO/C open-end rotor yarn samples producing by rotor type with narrowest groove, spiral navel type without notch and green torque type without twist stopping effect, led to lower unevenness, hairiness, IPI and higher breaking elongation.

Tekstil ve konfeksiyon sektörünün ana hammaddesi olan pamuk lifinin çevresel yük sorunu, lifin yaşam döngüsünün uzamasını zorunlu kılmaktadır. Ancak bilgi eksikliği, pamuğun geri dönüşümü ve işlenmesindeki engellerden biridir. Bu çalışmada, tüketim öncesi pamuk ürünlerinden (r-CO) elde edilen geri dönüştürülmüş pamuk lifleri ile işlenmemiş pamuk (C) liflerinin %50/50 oranlarında karışımlarından Open-end rotor iplikleri (OE-Rotor) eğrilmiştir. Üretim parametrelerinin (rotor tipi, navel tipi ve tork tipi) iplik özelliklerine etkileri incelenmiştir. Elde edilen sonuçlara göre, üretim parametrelerinin mukavemet değerleri dışında ölçülen tüm iplik özellikleri üzerindeki etkisi istatistiksel olarak anlamlıdır. En dar yivli rotor tipi, çentiksiz spiral navel tipi ve büküm durdurma etkisi olmayan yeşil tork tipi ile üretilen %50/50 r-CO/C open-end rotor iplik numunelerinin daha düşük düzgünsüzlük, tüylülük, IPI ve daha yüksek kopma uzaması değerleri gösterdiği tespit edilmiştir.
