Problems solved by technology

[0008] (1) Wormwood has the effect of repelling mosquitoes, but when used alone in fibers, the effect of repelling mosquitoes is average;
[0009] (2) During the fiber preparation process, the functional components of natural and herbal plants are easy to lose, and are also easily damaged by acid and alkali to cause losses;
[0010] (3) The functional components of the fiber cortex or surface are lost more during washing and friction, thereby reducing the mosquito repellent, antibacterial and antiviral effects of the fiber

Embodiment 1

[0044] Embodiment 1 A kind of preparation method of mosquito repelling antibacterial cellulose fiber containing wormwood composition

[0045] Include the following steps:

[0046] (1) Preparation of chitosan-functional component composite particles

[0047] Dissolve Radix Isatidis Extract, Apocynum Apocynum Extract, and Wormwood Extract in purified water to obtain a functional component solution with a mass concentration of 1.0 mg / mL; add the functional component solution at a rate of 26 mL / h with a mass concentration of 1.4 mg In the chitosan acetic acid solution of / mL, control the stirring speed to be 350r / min, add starch tertiary amino alkyl ether, then filter and defoam after stirring evenly, obtain the chitosan acetic acid solution containing functional components; then use 5ml It is sprayed into sodium hydroxide solution at a speed of 1-2 microns and granulated to generate chitosan-functional component composite particles of 1-2 microns.

[0048] The preparation method ...

Embodiment 2

[0068] Example 2 A preparation method of mosquito repellent and antibacterial cellulose fiber containing wormwood components

[0069] Include the following steps:

[0070] (1) Preparation of chitosan-functional component composite particles

[0071] Dissolve Radix Isatidis Extract, Apocynum Apocynum Extract, and Wormwood Extract in purified water to obtain a functional ingredient solution with a mass concentration of 1.2mg / mL; add the functional ingredient solution at a rate of 30mL / h with a mass concentration of 1.6mg In the chitosan acetic acid solution of / mL, the stirring speed is controlled to be 450r / min, and starch tertiary amino alkyl ether is added, then stirred evenly, filtered and defoamed to obtain the chitosan acetic acid solution containing functional components; then with 8ml It is sprayed into sodium hydroxide solution at a speed of 1-2 microns and granulated to generate chitosan-functional component composite particles of 1-2 microns.

[0072] The preparatio...

Embodiment 3

[0092] Embodiment 3 Synergistic effect of functional components

[0093] On the basis of Example 1, only change the ratio of mass parts of Radix Radix Radix Radix, Apocynum Apocynum Extract, Wormwood Extract, see Table 1 for changes, the total amount of the extract of each test is 5 parts by mass; measure Mosquito repellent effect of prepared fibers.

[0094] Table 1 Synergistic effect of functional ingredients

[0095]

[0096] It can be known from Table 1 that the compounding of Radix isatidis extract, Apocynum apocynum extract and Wormwood extract can improve the mosquito repellent effect of Wormwood extract and play a synergistic effect.

[0097] Unless otherwise specified, the percentages used in the present invention are all weight percentages, and the ratios described in the present invention are all mass ratios.

Abstract

The invention provides a mosquito repelling and antibacterial cellulose fiber containing wormwood components, the fiber, the content of chitosan-functional component composite particles is 9.0-9.3%, and the content of silicic acid composite colloid is 2.2-2.5%; The present invention also provides a preparation method of mosquito repellent and antibacterial cellulose fiber containing wormwood components, the preparation method comprising preparation of chitosan-functional component composite particles, preparation of silicic acid composite colloid, blending, spinning and forming. The fiber prepared by the present invention has a mosquito repellent rate of 99.5-99.8%; a bacteriostasis rate of 96.7-97.3% for Candida albicans; and a erythrocyte agglutination method for influenza A virus and influenza B virus, and the titers all reach 7 -8; the fiber prepared by the present invention, the content of chitosan-functional component composite particles is 9.1-9.3%, and the content of silicic acid composite colloid is 2.2-2.5%.

Description

technical field [0001] The invention relates to a mosquito-repelling and antibacterial cellulose fiber containing mugwort components and a preparation method thereof, belonging to the technical field of textiles. Background technique [0002] There are many methods of repelling and killing mosquitoes in the prior art, including drug killing, odor fumigation, ultraviolet light trapping, etc. At present, there are mosquito repellent fibers on the market. Mosquito repellent shirt, soaked in citronella essential oil, mosquitoes hate the smell of citronella essential oil, so it has a mosquito repellent effect; because essential oil is volatile, the active ingredients are lost more during the preparation of fibers and use; in addition, there is a mosquito repellent The formula of insecticide permethrin is added to the fiber to prepare mosquito repellent fiber, but the insecticide is a chemical component, which is harmful to health and cannot meet the needs of current consumers for...
