Yarn making method

A yarn making method, comprising a raw-material yarn;

• first rollers, which pull the raw-material yarn;
• an entangling point generator, which is arranged posterior to the first rollers to subject the yarn to jet-forming and generating of entangling points;
• a cleansing chamber, which is arranged posterior to the entangling point generator to cleanse the yarn that has generated the entangling points;
• a material chamber, which is provided with a graphene-containing attachment material to have the yarn that has generated the entangling points and has been cleansed attached with the graphene-containing attachment material;
• second rollers, which are arranged posterior to the material chamber to pull the yarn that has past the entangling point generator, the cleansing chamber, and the material chamber;
• a heating chamber, which is arranged posterior to the second rollers to have the graphene-containing attachment material provided from the material chamber securely attached to each individual fiber of the yarn by means of heat-setting;
• third rollers, which are arranged posterior to the heating chamber to control a heating time of the yarn in the heating chamber;
• and
• fourth rollers, which are arranged posterior to the third rollers;
• wherein the graphene attachment material has a length of 3-20 μm, a width of 8-25 μm, and a thickness of 3-12 nm.
