NOVELTY - The method involves pretreating the graphene fibers with a fiber wetting solution. A cotton fiber and graphene fiber are respectively subjected to a cleaning process, and the preliminary tearing is performed manually, and then a certain proportion of a combed sliver is selected to be torn and mixed in a cleaning disc. The cotton fibers and graphene fibers are combed, and a small gap is set between a licker-in roller and a cylinder. Six mixed bars are adopted to feed, and a drawing process is carried out. A roving frame of a drafting form of three rollers and double short apron is adopted to carry out the roving process. A three-roller mesh ring negative pressure type siro agglomeration spinning and spinning is adopted, and a spinning process is performed. The winding process is carried out, the yarn defects are cleared, the appearance defects are reduced, and a well-shaped packaged yarn is produced. USE - Method for preparing graphene blended yarn. ADVANTAGE - The fiber-wetting liquid is uniformly penetrated into the graphite fibers, the generation of static electricity is reduced, the cohesion force of the graphene fibers is improved, and the spinnability of the graphene fibers is enhanced. The method can prevent cotton fibers and graphene fibers from being deposited between the needle teeth, resulting in that the graphene fibers cannot be uniformly sent to the cylinder, which is beneficial to improve the high-quality mixing of graphene fibers and cotton fibers, by increasing the distance between the licker-in and the cylinder.
