How is fabric made from natural fibers?
The fibers collected thus are in no way ready to be made into pristine fabrics that we buy from shops ; they have to be scoured (cleaned) and bleached. These natural fibers are taken to the concerned mills and made into yarns of different kinds. The yarn is then knitted or woven into the final fabric.
