Problems solved by technology

[0005] (1) The existing technology is to add plant extracts to the spinning stock solution in the form of powder, which inevitably has problems such as strong acid, strong alkali, high temperature and other problems that cause the loss of effective substances of plant components, which not only affects the quality of the product , will also cause a great waste of resources;
[0006] (2) The prepared motherwort cellulose fiber has poor dry strength, wet strength and dry elongation at break due to the addition of plant components;
[0007] (3) The sustained release period of the active ingredients of Motherwort is short;
[0009] (5) With the washing process, the antibacterial effect becomes worse

Embodiment 1

[0037] Example 1 Preparation method of motherwort cellulose fiber with specification of 1.67dtex×38mm

[0038] (1) Selection of raw materials

[0039] The motherwort extract is selected as the raw material of the motherwort microcapsules. The motherwort extract is brown-yellow powder, 100% passed through 80 mesh, the motherwort content is 60%, the ash content is ≤3.2%, the moisture content is ≤3.8%, and the heavy metal content ≤5ppm, lead content ≤1ppm, arsenic content ≤0.5 ppm, mercury content ≤0.4 ppm, total number of bacteria ≤500cfu / g, total mold ≤50 cfu / g, Salmonella and E.coli shall not be detected.

[0040] (2) Preparation of motherwort emulsified dispersion

[0041] The motherwort emulsified dispersion is prepared by processing the motherwort extract and peach gum solution; the dosage of the motherwort extract and the peach gum solution is calculated in parts by weight; 5 parts of the motherwort extract and 3 parts of the peach gum solution are mixed Then heat to 52℃, stir an...

Embodiment 2

[0076] Example 2 Test the anti-allergic properties of fabrics woven with cellulose fibers of the present invention

[0077] Test parameters: skin redness (visual score), itching (subjective feeling of the subject), skin redness and swelling area (% of initial area)

[0078] Grouping: the present invention group and the control group, 30 people in each group;

[0079] Determination method: Use a specific test blade to drip histamine hydrochloride (5mg / ml) on the skin at the same position on the upper arm of all subjects. The low amount is 0.2ml. After 5 minutes, the skin will have redness, swelling and itching;

[0080] The group of the present invention wears clothes made of the fibers described in Example 1 of the present invention, and the control group wears clothes made of general cellulose fibers; 0h, 4h, 8h, 12h, 16h, 24h, measure the itching, redness and swelling of the test site The specific results are shown in Table 4-5;

Abstract

The invention provides a motherwort cellulose fiber. According to the fiber, the content of motherwort extracts is 8.2-8.5%, the dried break strength is greater than or equal to 4 cN / dtex, the wet break strength is greater than or equal to 2.2 cN / dtex, and the dried break elongation is greater than or equal to 24%. The invention further provides a preparation method of the fiber. The method comprises the steps of preparing motherwort gelatin fluid, preparing motherwort microcapsules, adding a dispersing agent, and preparing a spinning stock solution. According to the motherwort cellulose fiber prepared by the preparation method disclosed by the invention, the slow release period of effective components of motherwort is long, and reaches 1.5-2.5 years. According to the motherwort cellulose fiber prepared by the preparation method disclosed by the invention, the content of the motherwort extracts is 8.2-8.5%, the dried break strength is greater than or equal to 4 cN / dtex, the wet break strength is greater than or equal to 2.2 cN / dtex, the dried break elongation is greater than or equal to 24%, the quantity of residual sulfur is less than or equal to 4.2 mg / 100g, the rate of extra-long fibers is less than or equal to 1.0%, and long fibers are less than or equal to 10 mg / 100g.

Description

Technical field [0001] The invention relates to a preparation method of motherwort cellulose fiber, which belongs to the field of fiber preparation. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, people's pursuit of material and spiritual life, especially the concept of clothing, has also continued to change. People are paying more and more attention to the comfort and functionality of textiles. Traditional natural fibers such as cotton, linen, silk, and wool are affected by factors such as their own, natural climate, and land competition between grain and cotton, and their functionality and output are far from being able to meet actual needs. As the global energy crisis continues to erupt, the number of synthetic chemical fibers will not continue to grow. In recent years, the development of regenerated cellulose fibers has eased the pressure of insufficient production capacity of textile fibers. [0...
