The knitted fabric properties especially the dimensional characteristics are mainly influenced by the constituent fibres, yarn properties, knitting machine variables, processing and finishing treatments. Spun viscose knitted fabric is also susceptible for dimensional stability problems. In this paper, an attempt has been made to investigate the influence of pre shrink resin treatment on the dimensional characteristics of spun viscose knitted fabric especially single jersey structure. The 40 Ne spun viscose yarn has been knitted and the knitted fabrics is bleached, dyed and pre shrink resin treated. The influences of pre shrink resin on the weft knitted fabrics has been studied on repeated home laundering up to 25 wash cycles and various parameters of the knitted fabric are measured and analyzed. Pre shrink resin treated knitted fabrics exhibit minimum spirality variations and dimension changes compare than grey, bleached and dyed fabrics.

The manufacturing of the knitted fabric is always a challenge to the knitter. Weft Knitted fabrics are preferred as clothing materials in many kinds of application especially in under garments and easy care outer garments because of their outstanding comfort related qualities. Dimensional stability of the weft knitted fabrics has been one of the most discussed subjects in the textile industry as well as in research fields.
