▎ 摘　　要

NOVELTY - Preparing modified graphene polytrimethylene terephthalate (PTT) antistatic complex elastic fiber comprises (1) drying modified graphene PTT complex chips, melting, and extruding to obtain graphene PTT complex spinning melt, (2) feeding spinning melt into the spinning assembly through the pipe for spinning, and ejecting spinning melt from the spinneret to form filaments, and (3) cooling thread, oiling, stretching, shaping, performing alkali treatment, and winding to obtain graphene PTT antistatic complex elastic fiber. USE - The method is useful for preparing modified graphene polytrimethylene terephthalate (PTT) antistatic complex elastic fiber. ADVANTAGE - The elastic fiber has high integrity, good mechanical properties, comfortable feel and has high elasticity.
