The effect of raw material combination, yarn count, fabric structure and looplength on the thermal properties of Eri silk bi-layer knitted fabrics

Eri silk is one of the wild silk varieties which are mainly available in the north-eastern areas of India. It exhibits goodmechanical and thermal resistance properties. In this concern, the present study focused to develop a bi-layer knittedstructure made from Eri silk yarn as one side(next to skin) and on another side bamboo yarn knitted fabric. Similarly,Tencel knitted fabric was used instead of bamboo. Twenty-four bi-layer knitted fabrics were developed and thenanalysed for its thermal comfort property. The air permeability, and wick-ability were found to be higher and the thermalresistance was found to be higher for bi-layer plated interlocked knitted fabric made out of Eri silk compared to bambooand Tencel.
