Abstract

The invention relates to moisture absorption and sweat releasing polyester fibres and a preparation method thereof. According to a FDY process, a CDP melt and a PBT melt are distributed and extruded from spinneret holes on the same spinneret plate, so that FDY filaments are obtained; then, heat treatment without tension is carried out, so that moisture absorption and sweat releasing polyester fibres are obtained; the spinneret holes are shaped as shown in the specification; the shape as shown in the specification is composed of a transverse line and two vertical lines vertically connected withthe transverse line; the transverse line and the two vertical lines are same in width; the two vertical lines are same in length; the length ratio of the vertical line to the transverse line is (4-6):5; the length-to-width ratio of the two vertical lines is (6-8):1; the distance between the two vertical lines is 50-70% of the length of the transverse line; the midpoint of the connecting line of intersection points of the two vertical lines and the transverse line is the midpoint of the transverse line; distribution is that the CDP melt is controlled to flow through the transverse line and thePBT melt is controlled to flow through the two vertical lines at the same time; the finally prepared moisture absorption and sweat releasing polyester fibres have twisted form; the structure is easyfor water output; and the moisture absorption and sweat releasing performance is good.

Description

technical field [0001] The invention belongs to the field of fiber technology, and relates to a moisture-absorbing and sweat-wicking polyester fiber and a preparation method thereof. Background technique [0002] At present, domestic chemical fibers mainly use polyester filaments as raw materials, and the cross-section of chemical fibers is round or similar to round. Due to the poor hygroscopicity of polyester itself, it feels stuffy, airtight, and lacks comfort when worn, so it is in urgent need of improvement. At present, the more commonly used method is to design it as a shaped fiber with moisture permeability. [0003] Special-shaped fibers are generally prepared by specially designed and manufactured special-shaped spinnerets through special spinning processes, which is also the most commonly used method for producing special-shaped fibers at home and abroad. Producers can produce shaped fibers with any cross-sectional shape by improving and optimizing the processing t...
