假捻器夹角对涤纶DTY生产稳定性的影响

Effect of false twister angle on production stability of PET DTY

以261 dtex/36 f涤纶POY为原料,在33-H加弹机上生产涤纶DTY,探讨了生产过程中改变假捻器夹角(θ)对DTY生产稳定性的影响。结果表明:θ在105°～115°调节,θ为110°时DTY生产稳定,DTY成品丝为一等品。θ过小过大,DTY生产中都会出现抖丝、毛丝及僵丝等,生产不稳定。

A PET DTY was prepared from 261 dtex/36 f PET POY on a 33-H texturing machine： The effect of the variation of false twister angle （θ） on the production stability of DTY was discussed. The results showed that θ should be regulated in the range of 105° - 115°. The production was stable and the obtained DTY was the first-grade product when θ was 110°. The production was not sable and the wobble filament, split filament and ossified filament generated at extremely high or low θ.
