Investigation of the fastness properties and color strength of dry and wet reeled Tasar silk yarns

Abstract

Tasar silk is extremely sought-after due to its natural beauty, toughness, sustainability, and cultural significance. Despite the historical need for Tasar textiles in their natural hue, weavers have created a limited number of unique designs and variants of Tasar silk. Since the younger generation requires 100% Tasar fabric in a range of items with diverse patterns and color combinations, it has become more vital to dye the Tasar yarn a distinct color. The fastness characteristics and color strength of Acid, Reactive, and Lanaset dye on dry reeled and wet reeled Tasar silk yarns were compared in this paper. In order to assess the yarn samples' color intensity and resistance to rubbing, sweat, washing, and light, they were treated appropriately. The findings of the fastness test showed that, in comparison to other yarns, acid and reactively colored yarns had lower washing and sweat fastness, respectively. Better light fastness was seen in fibers colored with Lanaset. Comparing reactive dyeing to acid and Lanaset dyeing, the former demonstrated a stronger color.
