Physico-mechanical properties of Eri-modal blended yarn

Abstract

The present study was conducted to analyze the physical and mechanical characteristics of the developed Eri / Modal blended yarn. The diameter, count, fibre density and moisture content were observed maximum in Eri silk followed by modal. However Whiteness Index and the Initial Modulus were found to be highest in modal and lowest in Eri-silk. The results indicated that elongation per cent for Eri silk is higher as compared to modal fibre. In case of yarn, maximum twist, crimps were observed in controlled Eri silk (14.54tpi), (0.38 per cent). The lowest hairiness was observed Eri/Modal 30:70 (4.086/km) which was found least among all the blended as well as controlled yarns. It was also noticed that all the blended yarns exhibited maximum yarn strength than controlled yarns; it may be due to testing yarn with shorter gauge length which in turn enhances the apparent yarn strength. The experimental finding provides information on the properties of Eri silk and its blended yarns that were found to be better quality in respect of physical and mechanical properties than pure Eri/Eri fabric.
