Background

With the increasing awareness of environmental protection and health care, more and more people are paying attention to natural fibers, and cotton fibers are widely applied to the production of various textiles as the most common natural fibers. At present, yarns on the market come out endlessly, are different in material structure, and are widely applied to the living fields of weaving, rope making, thread making and the like. Xinjiang long staple cotton fiber is well known in the textile industry due to its softness and length, is known as a cotton top grade product by people, and has the advantages of less frequent combing, uniform and smooth evenness and high dyeability.
