Short answer
Despite the word "silk" in their names, commercial Dola Silk and Lichi Silk sarees sold wholesale in Surat are woven from a blend of fine viscose, modal, and polyester yarns on powerlooms and jacquard looms, engineered to replicate the rich luster and soft fall of pure Katan silk at a fraction of the cost.
