Embodiment 2

[0071] Example 2 The experiment that the isatidis cellulose fiber prepared by the present invention improves immunity

[0072] Experimental method: choose 600 people, be divided into 2 groups, the present invention group and control group, main symptoms are: mental stress, irritability and insomnia, easy fatigue, easy cold, low immunity; the course of disease is between 6-8 weeks;

[0073] The group of the present invention: try on textiles made of 100% isatidis fibers prepared by the present invention for 3 months;

[0074] Control group: tried on textiles made of ordinary fibers for 3 months;

[0075] Efficacy evaluation criteria:

[0076] Cure: Energetic, quick thinking, symptoms of waist soreness and leg weakness disappear, God can sleep peacefully, immunity is improved, and appetite is strong;

[0077] Significantly effective: 3 of the above symptoms have improved;

[0078] Effective: Those who have improved 2 of the above symptoms;

[0079] Ineffective: none of the a...

Embodiment 3

[0082] Example 3 Single Factor Analysis Experiment of Addition of Dispersant

[0083] Adopt the fiber preparation method described in embodiment 1, only change step 3, add dispersant step, the add-on of dispersant, carry out single factor analysis experiment, test the dry strength of the prepared fiber, wet strength, dry elongation at break, Bacteriostasis performance, adopt the method described in embodiment 2, test the effect that fiber improves immunity, see table 2 specifically.

[0084] Table 2 Single factor analysis experiment of dispersant addition amount

[0085]

[0086] From the above-mentioned single factor analysis experiment, it can be seen that embodiments 6 and 7 are preferred embodiments, that is, step 3, the step of adding dispersant, and the addition of dispersant is preferably 4-4.3%.

Abstract

The invention provides a radix isatidis cellulose fiber 5.5-5.56 cN / dtex in dry strength, 2.61-2.68cN / dtex in wet strength and 26.2%-26.7% in elongation at dry break. The invention further provides a preparation method of the fiber. The preparation method includes: adding a dispersing agent 4-4.3% in content. The slow release period of effective ingredients of radix isatidis in the radix isatidis cellulose fiber can reach more than 1.5 years; textile produced by adopting 100% of the radix isatidis cellulose fiber has functions of removing heat to cool blood, resisting viruses and enhancing immunity; the fiber prepared from the method is good in antibacterial effect, antibacterial rate to staphylococcus aureus reaches more than 9.4%, the antibacterial rate to escherichia coli reaches more than 99.5%, the antibacterial rate to monilia albicans reaches more than 97.5%, and after washing, the antibacterial effect is kept persistently.

Description

technical field [0001] The invention relates to a isatidis cellulose fiber and a preparation method thereof, belonging 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, is also constantly changing, and people are paying more and more attention to the comfort and functionality of textiles. Traditional cotton, hemp, silk, wool and other natural fibers are affected by factors such as themselves and natural climate, grain and cotton competition for land, etc., the functionality and output of the fibers are far from meeting the actual needs. With the continuous outbreak of the global energy crisis, the quantity of synthetic chemical fibers will also be difficult to continue to grow. In recent years, the development of regenerated cellulose fibers has eased the pressure of insufficient ...
