Özet

Murata vortex spinning system is based on the air jet spinning system. The vast majority of previous works deal with the properties of vortex spun (VS) yam and the spinning system. In this study, we investigated knitted fabrics from VS yam in comparison with fabrics from ring (RS), compact (CS) and open-end rotor (OES) spun yams made from viscose. The effect of yam spinning system on dimensional and physical properties of knitted fabrics was explained with specific attention to fabrics from VS yarn. Shrinkage of fabrics from VS yam has the lowest at widthwise direction, while having the highest at lengthwise direction. It is shown that the order of fabric spirality and twist liveliness for yams from different spinning systems are quite similar. However, relation between loop shape factor and angle of spirality is inconsistent. Angle of spirality of fabrics from VS yam is higher than fabrics from OES yam, but lower than that of others. The bursting strength of fabrics from VS yam is lower than that of those from RS and CS yams and higher than that of those from OES yam. From this study, it is also evident that fabrics from VS yam have the lowest pilling tendency and highest resistance to abrasion.
