Some properties of viscose fiber and cotton fiber are very similar, with good hygroscopicity, easy dyeing and antistatic property. The finished fabric is bright in color and comfortable to wear, especially in hot climates. Up to now, no synthetic fiber can match it in hygroscopicity and breathability, so viscose yarn products have developed rapidly in recent years, and many cotton spinning enterprises have started to produce viscose yarn.
To spin viscose yarn well, it is necessary to optimize and adjust the production equipment and technology. In the carding process, it is necessary to reduce the blow, replace the beating with carding, optimize the carding clothing, and comb moderately to reduce the generation of neps and short fibers; In the drawing process, a larger roller spacing is adopted to reduce accidental elongation and friction, and the appropriate roving twist coefficient is selected to reduce roving elongation. Spinning follows the principle of two big and two small processes, selects a reasonable friction boundary, optimizes the type of traveler, and completes three concentricity; Winding focuses on the quality of splicing and poor bobbin forming.
