Effects of properties of two-ply spun yarns produced directly by different systems on knitted fabric properties [Farkli sistemlerle direkt olarak elde edilmiş çift katli iplik özelliklerinin örme kumaş özelliklerine etkileri]

Bursting strength,pilling and abrasion properties of knitted fabrics,which were produced from six different direct two-ply yarns,were researched. the yarns were spun from two different raw materials by using three different spinning systems. bursting strength values of knitted fabrics,which were produced from both suessen compact siro and pinter compact siro yarns,were considerably higher than the ones produced from conventional siro-spun yarns. however,the differences between bursting strength values were not found statistically significant. pilling test results showed that fabric samples knitted from two-ply compact yarns had lower pilling tendency than the ones which were knitted from conventional siro-spun yarns. abrasion resistance of fabric samples knitted from compact sirospun yarns was higher in terms of both cycle of first yarn breakage and percentage weight loss. however,the most important differences between yarns of different spinning systems were obtained in tests which concerned weight loss. according to this,statistically significant differences were obtained between fabric samples which were knitted with conventional sirospun yarns of 20.5μm wool fibres and with two-ply compact spinning systems after 15000 abrasion cycles.
