| Abstract: | 111.1 dtex/144 f PET semi-dull multi-porous fine denier FDY can be successfully developed by using melt direct spinning process, Japanese TMT 32 ends DIO spinpaek （one spinpack provide two yarn）W type arrange- ment,external circular blow cooling device and automatic TMT ATI615MR/32 double winding machine. By selec- tion the technological conditions such as the melt pipeline conveying temperature at 281 - 283 ℃, the spinning tem- perature at 286 - 292 ℃, the heat-retarder temperature at 280 - 330 ℃, seletion of the calm zone height, prolong the length of the cooling closed wind cylinder, the collection position at 850 - 1 050 mm, using the dispersed pre-in- terlaced nozzle before GRI, the PET FDY with stable internal quality, dyeing stability and suitable for circular machine can be produced |
