Traditionally, eri silk woven fabric is stiff, rough and not easily drapeable, thereby concealing the intrinsic properties of texture, softness, bulkiness and colour of eri silk fibres. Diversification of eri silk products is the key element to withstand competition of other fibres and enhance its commercial potential in today‟s market. In this study three fabric combinations of eri silk namely, eri x eri, eri x tasar and eri x mulberry were prepared. The degummed and bleached samples were treated with three chemicals out of which one chemical was selected through visual evaluation of the samples of all fabric combinations. All samples were then treated with three concentrations (15, 25 and 35 percent) of selected chemical. The physical properties of all samples were tested and compared with that of the control samples. Then the treated samples were dyed with reactive and natural dyes and were assessed for colour fastness and colour strength. At last seven products were prepared and evaluated visually for assessing suitability of eri silk fabric combinations for prepared articles. Formic acid was selected for pretreatment of all fabrics in visual evaluation. The physical properties and colour strength of all fabrics were best on treatment with 35 percent formic acid. The colourfastness of the dyed fabric combinations was good and it improved with increase in the concentration of formic acid. The eri x eri fabric was considered more suitable for household articles, eri x tasar fabric for upper garments and eri x mulberry fabric for lower garments and home furnishing articles.ennullThesis
