Physio-mechanical properties of Eri silk and its union fabrics

Abstract

Union fabric is the fabrics where the warp yarns are different from weft yarns. Eri silk and wool is the way to incorporate better appearance in the woolen fabric and to increase the utility of silk fabric. Eri with wool union fabrics was found to be better quality in respect of physio-mechanical properties. The plain weave union fabrics of GSM (130) and 186 GSM as well as eri silk fabric with (85) GSM were prepared in fly shuttle loom. Union fabrics showed 38.80 mm and 0.88 mm fabric thickness, bending length of EWU was 2.16cm (warp) and 2.47 cm in weft but EWU1 union fabric showed 3.90 cm in warp and 2.98 cm in weft way. Decreasing trend was observed in crease recovery and bending length compared eri silk. Both union fabrics have good ultra-violet protection factor (UPF) but brightness index was found to be more in eri silk.
