Abstract:
A porous ultra-soft ultra-fine denier polyester fiber and preparation method. The modified polyester is spun with a porous spinneret to produce the porous ultra-soft ultra-fine denier polyester fiber, and the spinneret holes on the porous spinneret are arranged in an elliptical arrangement. The porous ultra-soft ultra-fine denier polyester fiber is obtained by metering, extruding, cooling, oiling and high-speed winding the modified polyester chips. The preparation method of modified polyester is as follows: terephthalic acid reacts with ethylene glycol to produce ethylene terephthalate. The modified polyester is obtained by the reaction of terephthalic acid with branched diol. The fiber of the invention has good properties and the deviation rate of fiber density. The deviation rate of fiber density is ≤0.5%, the CV value of breaking strength is ≤4.0%, the CV value of elongation at break is ≤8.0%, the CV value of yarn unevenness is ≤2.0%.

Claim (Index 8):
The method of  claim 2 , wherein the spinneret is a circular spinneret or an elliptical spinneret; a difference between a diameter of the circular :spinneret and a maximum length of the long axis of the series ellipse is greater than 10 mm and a difference value between the elliptical spinneret and the maximum length of the long axis of the series ellipse is greater than 10 mm.
