1. the production method of a high water absorbent polyester fiber is characterized in that:

  • 1. adopt conventional polyester section and high-hydroscopicity dacron master grain, both weight ratios are 100;

    5-10,2. terylene chips and the above-mentioned high-hydroscopicity dacron master grain with routine gives crystallization, drying respectively, and then gets into the electronic scale metering respectively, gets into the blender blend that band stirs after metering,3. push by screw extruder, fusion, homogenizing, metering,4. the melt after the homogenizing metering gets into operating temperature after 290-294 ℃

    manifold, is the spinnerets ejection of hollow type by spinneret orifice,5. add bullet and drawing-off coiling through coiling, drawing-off, produce POY, DTY and FDY long filament respectively.
