Example Embodiment

[0025] Embodiment 1 Raw material of wormwood extract

[0026] The wormwood extract raw material that the present invention selects is the wormwood extract powder, and the requirement of raw material is as follows:

[0027] Loss on drying < 5%, heavy metal content < 10PPM, ash content < 1.5%, pesticide residue < 2PPM, mesh size is

[0028] 80, total bacterial count <1000CFU / gm.

Example Embodiment

[0029] Example 2

[0030] A preparation method of viscose fiber containing wormwood extract, comprising the following steps:

[0031] (1) Preparation of antibacterial agent solution

[0032] Add the wormwood extract powder to water at a temperature of 25±1°C in an amount of 110g / 1000ml of water, stir well until the powder is completely dissolved to form an antibacterial agent solution, and obtain liquid A.

[0033] (2) Add dispersant

[0034] Add the dispersant to the above liquid A and stir to obtain liquid B.

[0035] (3) Add carboxymethyl cellulose sodium

[0036] Add carboxymethyl cellulose sodium powder into the above liquid B while stirring in a temperature range of 50-60°C in a certain mass ratio to obtain liquid C.

[0037] (4) Blending with spinning dope

[0038] The above liquid C was added to the spinning stock solution at a mass ratio of 15% of the spinning stock solution, stirred and dispersed, and then left to stand for vacuum defoaming to obtain liquid D....

Example Embodiment

Abstract

The invention provides a preparation method for a viscose containing wormwood extract. The preparation method comprises the following steps: preparing an antibacterial agent solution, adding a dispersing agent, adding sodium carboxymethylcellulose, blending with a spinning solution, spinning, and post-treating. The prepared viscose has the advantages that the dyeing effect is good, the antibacterial ability is high, the inhibition ratio to staphylococcus aureus is 99.1-99.3%, the inhibition ratio to escherichia coli is 98.9-99.3%, and the inhibition ratio to candida albicans is 93.6-95.7%. The prepared viscose has high strength and wet modulus; the dry strength is 6.21-6.34cN/dtex, the wet strength is 4.71-4.94cN/dtex, the elongation at break is 23.4-25.5%, and the wet modulus is 0.63-0.65cN/dtex.

Description

technical field [0001] The invention belongs to the technical field of man-made fibers, and relates to a method for preparing fibers, in particular to a method for preparing viscose fibers containing wormwood extract. Background technique [0002] Existing conventional viscose fiber is regenerated cellulose fiber, and its products have the characteristics of good moisture absorption and air permeability, and comfortable wearing. With the improvement of people's living standards and the change of life concepts, people pay more and more attention to the health care function of textiles, and hope that the existing viscose fiber textiles can be improved in terms of antibacterial properties; Insufficient antibacterial ability, low strength, poor dyeing effect, low wet modulus, resulting in unstable fabric size and other defects. [0003] The antibacterial agents and mosquito repellants used in antibacterial mosquito repellent fiber products are basically divided into three categ...
