 While a denim predecessor known as dungaree has been produced in India for hundreds of years, denim itself was first produced in the French city of Nîmes under the name “sergé de Nîmes”.The most common denim is indigo denim, in which the warp thread is dyed, while the weft thread is left white.As a result of the warp-faced twill weaving, one side of the textile is dominated by the blue warp threads and the other side is dominated by the white weft threads.
