KOMPAKT VE SİRO İPLİKLERİNİN DİNAMİK SÜRTÜNME ÖZELLİKLERİNİN KARŞILAŞTIRILMASI ÜZERİNE BİR ARAŞTIRMA

Bu çalışma, düşük iplik tüylülüğüne sahip (kompakt, siro, kompakt siro) iplikler ile konvansiyonel ring ipliklerinin dinamik sürtünme özelliklerini kıyaslamak amacıyla gerçekleştirilmiştir. Farklı eğirme sistemleriyle üretilen ipliklerin sürtünme özellikleri, farklı yüzey özelliklerine bağlı olarak değişiklik göstermektedir. Hammaddenin etkisini bertaraf etmek için, aynı pamuk fitilleri kullanılarak iplik tipi, iplik numarası ve fitiller arası mesafe (siro iplikler için) gibi çeşitli eğirme parametreleriyle özdeş iplikler üretilmiştir. İplikiplik sürtünme katsayısı (μYY),, iplik-metal sürtünme katsayısı (μYM) ve ipliklerin aşınma özellikleri CTT cihazı ile test edilmiştir. Sonuçlar incelendiğinde, eğirme yönteminin ve iplik inceliğinin ipliklerin sürtünme özellikleri ve döküntü oluşturma özellikleri üzerinde önemli etkisi olduğu ancak fitiller arası mesafenin iplik özelliklerini sınırlı düzeyde etkilediği tespit edilmiştir

A COMPARATIVE STUDY BETWEEN THE DYNAMIC FRICTION CHARACTERISTICS OF COMPACT AND SIRO YARNS

This study was conducted to compare the dynamic frictional properties of less-hairy yarns (compact, compact-siro and sirospun yarns) to conventional ring-spun yarns. Due to different surface characteristics affecting the frictional behavior, yarns spun by various spinning technologies differ from each other. Identical yarns of varying parameters including yarn type, yarn count, and strand spacing (for sirospun yarns) were produced from the same cotton roving to eliminate variability in raw material. Yarn-to-yarn friction (μYY), yarn-to-metal friction (μYM) and yarn abrasion characteristics of these yarns were determined by CTT instrument. The results have revealed that spinning method and yarn linear density have significant effects on the frictional and lint shedding features of the yarns whereas strand spacing has a limited influence on the yarn frictional properties
