▎ 摘　　要

NOVELTY - Processing melt-spinning fibers with special-shaped cross-sections and special forming comprises e.g. (i) drying main core carrier slice comprising polyethylene terephthalate, polyamide 6 or polyamide 66, first surrounding carrier slice, second surrounding carrier slice, third carrier slice and fourth surrounding carrier slice comprising polypropylene, polyethylene, polyacrylonitrile, polyvinyl chloride, polytrimethylene terephthalate, polybutylene terephthalate or 2-Ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine, (ii) melt blending and extruding main core carrier slices, flame-retardant powder and electrostatic supplement powder, cooling and pelletizing, (iii) melt blending and extruding first surrounding carrier slice and antibacterial powder, cooling and pelletizing, and (iv) melt blending and extruding second surrounding carrier slice and anti-ultraviolet powder, cooling and pelletizing. USE - The method is useful for processing melt-spinning fiber with special-shaped cross-sections and special forming. ADVANTAGE - The melt-spinning fiber has glossiness of triangular cross-section fibers, good comprehensive mechanical properties and large specific surface area, and has good thermal dimensional stability at high temperatures. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart illustrating the method for processing melt-spinning fiber (Drawing includes non-English language text).
