Wherein, in said POY-DTY technology, the process route of POY is: screw extruder → prefilter → static mixer → measuring pump → filament spinning component → spray silk → lateral blowing oils → path → POY undrawn yarn; Wherein: spinning temperature: 270-275 ℃; The lateral blowing condition: wind speed is 0.2-0.3 m/s, wind-warm syndrome 20-30 ℃, relative humidity 60-75%; The rate of oiling is 0.8-1.8%; Spinning speed is 3500-4500 m/min; Wherein, the DTY production process route is: the hot case → coldplate of thread guide → feeding roller → first → false twister → delivery roller → oiling device → DTY undrawn yarn; Wherein, first heater temperature is 150-175 ℃, and D/Y ratio is 1. 2-1.5, and drafting multiple is 1.15-1.30.
Wherein, described anti-oxidant is a hindered phenol anti-oxidants 1010.
Wherein, described catalyst is the mixture of zinc chloride and magnesium sulfate, and the amount ratio of the two is 1:1.
Wherein, described dispersant is a PLA.
Wherein, described delustering agent is a titanium dioxide fine particles.
Compared with prior art; The present invention has following beneficial technical effects: used to 1. the invention property pyrroles's aromatics raw material; Add specific metal salt catalyst simultaneously and change the nylon melt structure, prepared the DTY false-twist textured yarn with delicate fragrance fragrance, the fragrance durability is long; And good stability, weave the different demands of arrangement processing after can satisfying.2. through adjustment related process parameter, the nylon 66 DTY false-twist textured yarns that technology of the present invention is applicable to preparation 20D-70D add delustering agent simultaneously and can prepare corresponding full-dull false-twist textured yarn.
