摘　　要：研究了防紫外线细旦丙纶DTY生产工艺及其对纤维性能的影响。选择变形速度 40 0～5 0 0m/min ,拉伸倍数 1.4～ 1.6,D/Y比 1.60 ,第一热箱温度 ( 15 0± 5 )℃ ,第二热箱温度 12 0～ 13 0℃ ,纤维品质优良 ,一等品率达 95 % ,紫外线遮挡率大于 99%。The production process of antiultraviolet fine denier polypropylene DTY and its effect on the properties of the fiber were studied. The fiber with ultraviolet screening percentage higher than 99% can be produced under the conditions as followed: texturing speed 400～500 m/min, draw ratio 1.4～1.6, D/Y ratio 1.60, the first heat box temperature (150±5)℃, the second heat box temperature 120～130℃. The resulted fiber had wonderful physical index and top-class percentage of 95%.
