Embodiment 1

[0048] Embodiment 1 A kind of preparation method of meteorite polyester fiber,

[0049] Include the following steps:

[0050] S1: Prepare stone needle polyester resin slices;

[0051] S2: After the Bianstone polyester resin slices are dried, they are fed into the screw extruder, and the Bianstone polyester resin slices are melted in the screw extruder;

[0052] S3: The melted meteorite polyester slice fluid passes through the spinning box and the metering pump, and then is sprayed out through the spinneret holes to form fiber filaments;

[0053] S4: The formed fiber strands are cured after being blown by the tunnel ring; the cured fiber strands are subjected to post-treatment processes such as oiling on tankers and drafting to obtain meteorite polyester fibers.

Abstract

The invention provides stone needle polyester fiber. The content of stone needle micro powder in the fiber is 0.5-5%, and the content of an electric conduction enhancer is 5-10%. The far infrared emission rate of the textile prepared by adopting the stone needle polyester fiber is 92%. The invention further provides a preparation method of the stone needle polyester fiber. The preparation method comprises the step that S1 a stone needle polyester resin section is prepared; in the step 1, the stone needle polyester resin section is prepared from raw materials: 65-70% of polyester high polymer resin section, 5-13% of electric conduction fluid, 0.5-5% of stone needle nano micro powder, 5-10% of electric conduction enhancer and 0.5-1% of dispersing agent. Stone needle in a traditional Chinesemedicine therapy is adopted to serve as a base material and added into the spinning processing process of modern polyester, and thus the prepared fiber has the functions of releasing infrared rays andconducting electricity at the same time.

Description

technical field [0001] The invention relates to a polyester fiber and a preparation method thereof, in particular to a meteorite polyester fiber and a preparation method thereof.
