[0007] Patent No. "CN201910720453.4" titled "A Ginger Health-Care Cellulose Fiber and Its Preparation Method" provides a ginger health-care cellulose fiber. Gingerol is blended and added to a wet-spinning process to prepare a Cellulose fiber with ginger health function, but its function persistence is poor, and the mechanical properties of the fiber are also reduced
[0008] Although Tencel fiber has many advantages, when used as a textile fiber, the fiber is prone to fibrillation due to friction during processing and use, which affects the quality of yarn and fabric during spinning and weaving. After the fabric is used for a period of time, the surface The fluffing phenomenon will affect the smooth feel of the fabric or the old feeling of the color, and the service life will be low. Therefore, it is necessary to improve the fibrillation of the tencel fiber while satisfying the fiber functionality, which is of great significance to the production and promotion of the tencel fiber. important meaning

[0056] 1. Preparation of cellulose lysate

[0057] 1. Swelling of cellulose pulp

[0058] Immerse the cotton pulp in deionized water and stir ultrasonically for 15 minutes to fully swell the cellulose and reduce the ash content in the pulp.

[0059] 2. Enzyme hydrolysis

[0060] Dehydrate the swollen cotton pulp to a water content of 13%, put it into a reaction kettle, add cellulase solution and buffer solution, adjust the pH to 5, stir at 50°C for 4 hours, and the stirring speed is 200r / min. After stirring, the enzyme is killed at high temperature. Cellulose was obtained after filtering and drying at 80°C for 2.5 hours;

[0061] The ratio of the cellulase solution to the pulp is 25:1; the cellulase content in the cellulase hydrolysis solution is 6%;

[0062] The buffer is 0.1 mol / L phosphate buffer and 0.15 mol / L sodium citrate buffer, the ratio of the two i...

Embodiment 2

[0082] Embodiment 2 A kind of ginger extract fiber and preparation method thereof

[0083] The difference between this embodiment and Example 1 is that the preparation steps of the cellulose dissolving solution are different, and the rest are consistent with Example 1, specifically as follows:

[0084] 1. Swelling of cellulose pulp

[0085] Immerse the bamboo pulp in deionized water and stir it ultrasonically for 13 minutes to fully swell the cellulose and reduce the ash content in the pulp.

[0086] 2. Enzyme hydrolysis

[0087] Dehydrate the swollen bamboo pulp to a water content of 15%, put it into a reaction kettle, add cellulase solution and buffer, adjust the pH to 5.5, stir at 45°C for 3.5h, and the stirring speed is 150r / min, and then inactivate the enzyme at high temperature after stirring , filtered and dried at 85°C for 2 hours to obtain cellulose;

[0088] The ratio of the cellulase solution to the pulp is 20:1; the cellulase content in the cellulase hydrolysis ...

Embodiment 3

[0095] Embodiment 3 A kind of ginger extract fiber and preparation method thereof

[0096] The difference between this embodiment and embodiments 1 and 2 is that the preparation steps of the cellulose dissolving solution are different, and the rest are consistent with embodiments 1 and 2, specifically as follows:

[0097] 1. Swelling of cellulose pulp

[0098]Immerse the wood pulp in deionized water and stir ultrasonically for 18 minutes to fully swell the cellulose and reduce the ash content in the pulp.

[0099] 2. Enzyme hydrolysis

[0100] Dehydrate the swollen wood pulp to a water content of 10%, put it into a reaction kettle, add cellulase solution and buffer solution, adjust the pH to 4.5, stir at 50°C for 3 hours, and the stirring rate is 250r / min, and then inactivate the enzyme at high temperature after stirring. Cellulose was obtained after filtering and drying at 75°C for 3 hours;

[0101] The ratio of the cellulase solution to the pulp is 25:1; the cellulase con...

Abstract

The invention provides a ginger extract fiber and a preparation method thereof. Extracts of green tea, gallnut, mint, sarcandra glabra and ginger are added into a cellulose dissolving solution, then a binding agent is added, the prepared fiber has the dry breaking strength of 3.51-4.08 cN / dtex and the wet breaking strength of 2.02-2.64 cN / dtex, the fiber has high mechanical performance, meanwhile, fibrillation of the fiber is improved, and the fibrillation grade is 1. The surface of the fiber is smooth and flat and is superior to that of common tencel fiber in the market, the service life of the fiber is prolonged, the practicability of the tencel fiber is enhanced, the tencel fiber is not prone to pilling after being rubbed, and the quality of yarn and fabric is effectively improved in the spinning process; and by adding the plant extracts, the fiber has a natural antibacterial effect, the antibacterial rate to staphylococcus aureus is greater than 99%, the antibacterial rate to klebsiella pneumoniae is greater than 99%, the antibacterial rate to candida albicans is greater than 98%, the antibacterial effect is lasting, and the antibacterial loss rate is lower than 2% after the fiber is washed 100 times.

Description

technical field [0001] The invention belongs to the field of fiber technology, and in particular relates to a ginger extract fiber and a preparation method thereof. Background technique [0002] Tencel fiber, commonly known as "Tencel", is made of natural plant fibers and has many excellent properties of both natural fibers and synthetic fibers. The environmental protection advantages that traditional viscose fibers do not have are widely used in clothing, home textiles, non-woven fabrics and other fields. [0003] With the different needs of people's life, higher requirements are put forward for the function and performance of the fiber. Adding functional additives to the spinning solution can endow the fiber with antibacterial, magnetic therapy, heating, and promoting human blood circulation. . [0004] Ginger generally refers to the rhizome of the perennial herb ginger. In traditional Chinese medicine, it mainly has the effects of relieving cough, vomiting, and dispersi...
