▎ 摘　　要

NOVELTY - A graphene-terylene composite masterbatch comprises 0.05-2% terylene polyester slice, and 1.5-4.5% biological protein powder. USE - A graphene-terylene composite masterbatch used for preparing graphene-polyester composite fiber (claimed). ADVANTAGE - The composite masterbatch has soft handfeel, good skin-friendly property, good humidity absorbing performance, no static electricity, strengthened cohesion force, and has improved spinning. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the graphene-terylene composite masterbatch, comprising mixing terylene polyester and biological protein powder to prepare a biological protein-terylene composite powder; and extruding in sections at 120-150Hz and 268 degrees C, 278 degrees C, 282 degrees C, 285 degrees C, and 278 degrees C.
