BAZI ÖRME KUMAŞ ÖZELLİKLERİ AÇISINDAN PAMUK VE VİSKON VORTEX, OE-ROTOR VE KONVANSİYONEL RİNG İPLİKLERİN KARŞILAŞTIRILMASI ÜZERİNE BİR ÇALIŞMA

Bu çalışmada, çeşitli iplik numaralarında pamuk ve viskon liflerinden üretilen vortex, OE-rotor ve konvansiyonel ring ipliklerin bazı iplik ve kumaş özellikleri karşılaştırılmıştır. Özellikle, vortex ipliklerin iplik içerisindeki lif dağılımı, iplik-iplik ve iplik-metal sürtünme katsayıları, tekrarlı yıkama sonrası emicilik, kuruma davranışı ve yanmaya karşı direnç özellikleri incelenmiştir. Çalışma sonunda, beklenenin aksine, vortex eğirme sisteminin OE-rotor ve konvansiyonel ring ipliklere kıyasla her zaman az tüylü iplik üretemediği ve iplik tüylülüğünün kullanılan elyaf türü ve iplik numarasına bağlı olarak değiştiği belirlenmiştir. Ayrıca, elde edilen sonuçlar doğrultusunda vortex iplikler orta derecede iplik düzgünsüzlüğü ve iplik-iplik sürtünme katsayısı, düşük mukavemet ve kopma uzaması, yüksek iplik-metal sürtünme katsayısı, sert iplik karakteri, yıkamaya karşı yüksek direnç ancak yanmaya karşı düşük direnç özellikleri ile karakterize edilmiştir

A COMPARITIVE STUDY ABOUT SOME OF THE KNITTED FABRIC PROPERTIES OF COTTON AND VISCOSE VORTEX, OE-ROTOR AND CONVENTIONAL RING SPUN YARNS

In this study, some of the yarn and fabric properties of vortex, OE-rotor and conventional ring spun yarns produced from cotton and viscose fibres in three different yarn counts were compared. Particularly, fibre distribution in yarn structure yarn-to-yarn and yarn-tosolid friction properties, water absorbency after repeated washings, drying and flame resistance of vortex yarns were investigated. The results indicated that contrary to expectations, vortex spinning system cannot always enhance to produce the less hairy yarns than OErotor and ring spun yarns, and hairiness of vortex yarns changes depending on fibre type and yarn count. Furthermore, vortex yarns were characterized with the moderate yarn irregularity and yarn-to-yarn coefficient, lowest strength and elongation, highest yarn-to-solid friction coefficient, stiffer character, higher water uptake and quicker water absorption, slower drying ability, higher resistance to washing but lower durability to the ignition

Keywords:

Vortex yarn, water absorbency, hairiness, fabric drying, spinning systems,
