Embodiment 1

[0021] A method for preparing citronella fiber, comprising the following steps,

[0022] The first step is to prepare the citronella extract adding solution, add the citronella extract to the dispersant solution in the dissolution tank, stir at 38±2°C for 50-55 minutes, and at the same time turn on the microsphere grinding pump for circulating grinding and dissolving, after filtration Obtain 25-30wt% crude citronella extract solution in the blending tank;

[0023] For example, the citronella extract is added to the dispersant solution in the dissolving tank, stirred at 40°C for 52 minutes, and at the same time, the microsphere grinding pump is turned on for circulating grinding and dissolving, and after filtration, a 28wt% crude citronella extract solution is obtained in the blending tank ;

[0024] Then add a stabilizer to the blending tank, the weight is 0.05-0.08wt% of the dry powder quality of the citronella extract solution, the rotating speed is 50-60 rpm, the stirring ...

Embodiment 2

[0034] A method for preparing citronella fiber, which is similar to Example 1, except that the particle size distribution of the citronella odor essential oil sustained-release microcapsules is D90≤2 microns.

[0035] It can also be specifically, in the fourth step, the thread drawing process includes: nozzle drafting, inter-disc drafting and plasticizing bath drafting, nozzle drafting 22%, inter-disc drafting 30%, plasticizing bath drafting 15% %.

[0036] Also specifically, in the fourth step, the post-processing step includes: cutting, washing with water, desulfurization, washing with water and oiling.

[0037] Also specifically, the desulfurization step uses sodium sulfite for desulfurization, the concentration of sodium sulfite is 5g / l, and the temperature is 50°C.

[0038] Also specifically, in the first step, the citronella extract is citronella extract powder.

[0039] Also specifically, the citronella extract powder has a weight loss on drying ≤ 3%, a heavy metal co...

Abstract

The invention discloses a preparation method of a cymbopogon citratus fiber. The preparation method comprises the following steps of preparing a cymbopogon citratus extract addition solution, preparing a modified adhesive, preparing a cymbopogon citratus blended adhesive, and carrying out spinning and post-treatment. The cymbopogon citratus fiber has various effects of refreshing brain, harmonizing stomach, preventing asthma, and preventing mosquitoes and the like.

Description

technical field [0001] The present application relates to the technical field of man-made fibers, in particular to a method for preparing citronella fiber. Background technique [0002] At present, with the improvement of people's living standards, more and more artificial fibers are used in textiles, etc., and their requirements are getting higher and higher. The artificial fibers in the prior art include mint composite cellulose fibers, grass coral extracts, etc. The preparation method of substance and wormwood extract, although the man-made fiber that above-mentioned preparation method gained has certain effect of optimizing smell and bacteriostasis, but it mostly exists and cannot possess effects such as refreshing the brain, harmonizing the stomach and ventilating. Contents of the invention [0003] The present application proposes a preparation method of citronella grass fiber to solve the problems existing in the prior art that it cannot have the functions of refres...
