▎ 摘　　要

NOVELTY - Non-elastic core-spun yarn of polyester/sea-island fiber comprises core filament and covered fiber. The core fiber is FDY polyester filament. The coating fiber is sea-island fiber. The preparation method of the sea-island fiber includes (S1) mixing the island component and zinc oxide-graphene nanocomposite particles and then melt-blending under the action of ultrasonic waves and microwaves, and carrying out extrusion and granulation to obtain island-phase functional masterbatch, (S2) after mixing the sea component and the island-phase functional masterbatch, melt blending and spinning to obtain sea-island raw silk, (S3) carrying out oiling, stretching, crimping, drying and cutting operations by the sea island raw silk to obtain sea island thick silk, and (S4) subjecting the sea-island thick filaments to fiber-opening treatment to obtain sea-island fibers. USE - The polyester/sea-island fiber is useful for fabric in the field of textile. ADVANTAGE - The polyester/sea-island fiber has excellent anti-bacterial function and anti-static property, and provides fabric with soft and comfortable hand feeling. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a fabric.
