▎ 摘　　要

NOVELTY - Preparing graphene high-heat-dispersion fiber involves (a) weighing raw materials in proportion, (b) preparing graphene ultrafine powder, (c) stirring and mixing the graphene powder and the chinlon powder, (d) performing composite granulation on the mixed powder through melt extrusion to prepare graphene chinlon master batches, (e) pouring the composite master batch into a spinning machine for spinning, (f) mixing the graphene nylon yarns with viscose fibers to form yarns, (g) preparing high heat dissipation slurry, (h) soaking through a slurry tank, and uniformly coating the high-heat-dissipation slurry on the surface of the graphene nylon filament yarn, (i) drying the coated composite fiber in a dryer to enable the coating to be solidified and formed on the surface layer of the fiber, and (j) winding the dried high-heat-dissipation fibers into a cone-shaped yarn for later use. USE - Method for preparing graphene high-heat-dispersion fiber. ADVANTAGE - The graphene high-heat-dispersion fiber has good heat dissipation effect, obvious cold feeling, large thermal conductivity, good heat conduction effect, and stable mechanical properties.
