Hemp gray yarn began to be produced mainly with pure cotton, and has gradually developed into polyester/cotton hemp gray yarn, pure polyester hemp gray yarn and pure viscose hemp gray yarn. Although with the advancement of spinning technology, the variety of mélange yarns continues to develop, hemp gray yarn is suitable for enterprises because of its simple process and small color changes of raw materials. Therefore, it still occupies a large proportion in the production of mélange yarn.
