Embodiment 1

[0035] Preparation of pearl powder

[0036] 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. Then add water and stir to form a 25-40% slurry, and send it into the high-pressure tank of the high-pressure expansion equipment. The steam pressurizes the slurry, and then enters the expansion chamber through the expansion valve and returns to the normal condition. Repeat 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%.

[0037] If the particle size of the powder added to the fiber is large, it will not only bloc...

Embodiment 2

[0039] Mix 1.95kg matrine, 0.9kg Kochia saponins, and 0.15kg puerarin into 3L of water, mix 6.9kg palm oil and 0.1kg HLB of triglycerides to prepare an oil phase, and stir Next, the water phase is added into the oil phase to prepare the Chinese medicine extract microemulsion. 4 kg of pearls were crushed according to the crushing method in Example 1 to prepare pearl powder, and the fineness of the pearl powder was D95≤0.1 μm.

[0040] Disperse 0.02kg of toluene diisocyanate and 0.7g of dibutyltin dilaurate in water to form a crosslinking agent solution, heat 0.21kg of polyethylene glycol with a molecular weight of 400 to 60°C to melt, and micronize the pearl powder and traditional Chinese medicine extract After the milk is mixed, it is dispersed in molten polyethylene glycol, stirred for 12 hours, immersed in the cross-linking agent solution, and dried to obtain the inner layer of pearl powder and Chinese medicine extract microemulsion, and the outer layer of polyethylene glyco...

Embodiment 3

[0043] Mix 1kg matrine, 0.8kg Kochia saponin, and 0.2kg puerarin into 2L water to prepare the water phase, mix 2.9kg soybean oil and 0.1kg HLB of 6 sucrose ester to prepare the oil phase, and stir The water phase is added into the oil phase to prepare the Chinese medicine extract microemulsion. 5.5 kg of pearls were pulverized according to the pulverization method of Example 1 to prepare pearl powder, and the fineness of the pearl powder was D95≤0.1 μm.

[0044] Disperse 0.02kg of triisocyanate and 0.7g of dibutyltin dilaurate in water to form a cross-linking agent solution, heat 0.075kg of polyethylene glycol with a molecular weight of 600 to 60°C to melt, and microemulsion the Chinese medicine extract and pearl powder After mixing, disperse in melted polyethylene glycol, stir for 5 hours, and immerse in the crosslinking agent solution. After drying, the inner layer is microemulsion of pearl powder and traditional Chinese medicine extract, and the outer layer is polyethylene ...

Abstract

The invention provides pearl and traditional Chinese medicine eczema-preventing regenerated cellulose fiber and a preparation method thereof. The pearl and traditional Chinese medicine eczema-preventing regenerated cellulose fiber comprises the following components in percentage by weight of 2-5.5 wt% of pearl powder and 2-3 wt% of traditional Chinese medicine extract. The traditional Chinese medicine extract is prepared from the following components in percentage by weight of 50 to 70 wt% of sophocarpidine, 20 to 40 wt% of icmomordin and 5 to 10 wt% of puerarin. According to the pearl and traditional Chinese medicine eczema-preventing regenerated cellulose fiber, the pearl powder is good in dispersity and not prone to agglomeration, and the lipophilicity can be changed to the hydrophilicity. The pearl powder and the traditional Chinese medicine extract 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 base to the traditional Chinese medicine extract in the spinning process can be avoided. The fiber disclosed by the invention has the functions of preventing eczema and protecting health and skin, 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 a pearl traditional Chinese medicine anti-eczema regenerated cellulose fiber and a preparation method thereof. Background technique [0002] Basic necessities of life are closely related to people's life. In the field of textiles, people are not only satisfied with comfort and beauty, but also continue to actively develop healthy and environmentally friendly functional textiles, and have successively launched many textiles with health care and medical functions, such as promoting blood circulation, relieving itching and anti-inflammatory, whitening and anti-ultraviolet rays, etc. . [0003] CN102493207A relates to a preparation method of a regenerated cellulose fabric with calming and health-care effects. adding sweet orange essential oil into polyurethane and water, stirring, adding a microcapsule solution and fully stirring, adding a dispersant, an adhesive and a softe...
