Embodiment 1

[0046] Embodiment 1: a kind of preparation method of colored light body fiber, carry out according to the following steps:

[0047] (1), slice drying:

[0048] The moisture content in the slices must be reduced before spinning. Low-speed spinning requires the moisture content of the slices to be below 0.005%, while high-speed spinning requires the moisture content of the slices to be below 0.003%. The moisture content of the slices should be uniform and the amount of powder should be less;

[0049] (1), pre-crystallization hot air circulation system treatment:

[0050] The slices enter the pre-crystallization fluidized bed, and the air is blown into the slices from bottom to top through the mesh plate. The inclination angle of the mesh plate is 65 degrees, which takes away the dust in the slices. Each slice is fully exposed to the gas, and the heat transfer efficiency is high. During the crystallization process, the pre-crystallization is carried out uniformly and continuousl...

Abstract

The invention relates to a colored lightweight fiber, in particular to a fabrication method of the colored lightweight fiber. The method comprises the following steps of drying slices, using a masterbatch syringe, entering a screw extruder, winding to form, and spinning after the winding. According to the fabrication method of the colored lightweight fiber, the structure is compact; the grade of a product is raised; and the quality of the product is improved.

Description

technical field [0001] The invention relates to a colored lightweight fiber, in particular to a preparation method of the colored lightweight fiber. Background technique [0002] The preparation method of the colored light-weight fiber in the prior art is complicated, and the product quality cannot be guaranteed, which affects the quality of downstream products. Contents of the invention [0003] The invention mainly solves the deficiencies existing in the prior art, and provides a preparation method of colored light-weight fiber with scientific and reasonable preparation method and improved product quality. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A kind of preparation method of colored light body fiber, carry out according to the following steps: [0006] (1), slice drying: [0007] The moisture content in the slices must be reduced before spinning. Low-speed spinning requires the mois...
