[0033] Pulverization of Experimental Example 1 Pearl

[0034]After the raw pearls are selected and cleaned, they are mixed with water and placed in a stirring ball mill, and the pearls are coarsely crushed to about 5 μm by the pressure and shear force generated. The obtained coarsely crushed pearl slurry is sent into the high-pressure tank of the high-pressure expansion device, and the steam pressurizes the pearl slurry, and then enters the expansion cavity through the expansion valve and returns to normal conditions, and repeats at least three times. Repeated high-pressure expansion for many times - after decompression to conventional conditions, the pearl layer will expand between the layers, easy to loosen, and then grind by jet crushing technology or wet grinding and crushing method. The fineness of the obtained pearl powder reaches D95≤0.1 μm, and the degree of dispersion is greater than 90%. If the particle size of pearl powder is large, it will not only block the machi...

[0035] The pretreatment of experimental example 2 pearls

[0036] Through the pretreatment of the pulverized pearl powder, the effect of pretreatment on improving the lipophilicity and dispersibility of the pearl powder was further explored. Since pearl powder is a hydrophilic and oleophobic substance with a large specific surface area and is easy to agglomerate, it is added to fibers to make textiles, and the skin's absorption effect is poor. If it can be changed from hydrophilic to lipophilic, it can be better in contact with people's skin, and it is more conducive to the effect of pearls. At the same time, the more evenly the pearl powder is dispersed, the more favorable the spinning process and fiber quality will be.

[0037] Add water to the pulverized pearl powder to prepare a 20-35% slurry. The pretreatment method is to add Span 80, polyethylene glycol 400 and vegetable oil, such as palm oil and corn oil, to the pearl slurry. The added amounts of Span 80, polyethylene...

[0044] Experimental Example 3 Study on the Preparation Technology of Chinese Medicine Extract Microcapsules

[0045] Through the following examples and comparative examples, we explore the process research of preparing microcapsules using artemisinin and its derivatives and borneol as Chinese medicine extracts. Artemisinin and its derivatives are extracted from Artemisia annua plants using existing extraction methods. Ice products are purchased from the market.

Abstract

The invention provides erythema-preventing regenerated cellulose fiber containing pearl and traditional Chinese medicine and a preparation method of the erythema-preventing regenerated cellulose fiber. The erythema-preventing regenerated cellulose fiber containing the pearl and the traditional Chinese medicine comprises 2-5.5 wt% of pearl powder and 2-5 wt% of a traditional Chinese medicine extract. The traditional Chinese medicine extract comprises 80-90% of artemisinin and derivatives thereof and 10-20% of borneol. According to the erythema-preventing regenerated cellulose fiber containing the pearl and the traditional Chinese medicine, the pearl powder is good in dispersity and not prone to agglomeration. The artemisinin, the artemisinin derivatives and the borneol are coated by preparing a microcapsule, the size of the microcapsule is small, spinning is not affected, and the damage of strong acid and strong alkali to the artemisinin, the artemisinin derivatives and the borneol in the spinning process can be avoided. The fiber disclosed by the invention has the functions of protecting skin and preventing erythema, and can still play a role after being repeatedly washed with water.

Description

technical field [0001] The invention relates to the technical field of textile fibers, in particular to anti-erythema regenerated cellulose fibers containing pearl Chinese medicine and a preparation method thereof. Background technique [0002] Health and environmental protection are the themes in recent years, which have attracted people's attention in all aspects of life. Basic necessities of life are closely related to everyone's life. In the field of textiles, in addition to meeting people's requirements for warmth and comfort, they must also have health care functions. Therefore, various functional textiles emerge in an endless stream, such as textiles with functions such as antibacterial and mite removal, moisturizing, antistatic, and self-cooling. These textiles take into account both fashion and health, thus becoming the top grade that people pursue. [0003] In order to achieve the functional effect of textiles, the following technologies are usually required: Fi...
