Abstract:

This paper focuses on the dimensional and selected physical properties of a series of plain jersey fabrics made from viscose siro-spun and carded ring yarns of 2/10 tex and 20 tex, respectively. Elastane yarn was incorporated into the fabric using the plaiting technique. In general, for both greige and dyed knitted fabrics, the stitch density decreased, whereas the weight increased as the stitch length increased. Moreover, for greige and dyed dry-relaxed fabrics from siro yarn, the twist had an influence on fabric properties, the effect being relatively more prominent for slack samples. Moreover, both slack and tight dry relaxed dyed samples from high twist siro yarns featured lower resistance to abrasion. As far, as dyed and laundered samples from siro yarns are concerned, the results revealed that irrespective of the loop length, the samples from average twist siro yarns tended to give a higher stitch density and weight values. When abrasion resistance values of samples from both average and high twist siro yarns were studied, it could be suggested that in addition to yarn properties, the effect of fabric properties on the abrasion behaviour of the samples became more prominent after laundering. As far as the abrasion resistance and pilling properties of the samples are concerned, the fabrics from siro-spun yarns tended to perform better. Finally, the pilling test method employed affected not only the size and shape of the pill entanglements on the surface of the samples but also the degree of fibre damage within the fuzz entanglements.
