Description

Technical Field

[0001] The invention belongs to the technical field of skin care fabrics, and in particular relates to an anti-ultraviolet skin care fabric doped with rare earth elements and a preparation method thereof. Background Art

[0002] Whether it is cloudy or sunny, day or night, you should take good sun protection. Sun protection is mainly to reduce the damage of ultraviolet rays to the skin. Even if we can't see the sun, ultraviolet rays still exist, so we must also take sun protection measures. One way to protect yourself from the sun is to wear sun-protective clothing.

[0003] However, the existing sunscreen fabrics have a single component and the principle of sunscreen is relatively simple, that is, anti-ultraviolet sunscreen is provided by simply blocking light. When the light shines on the fabric, it cannot be completely blocked by the fabric. The light that shines on the skin through the fabric is absorbed by the skin after multiple reflections between the fabric and the skin, causing the skin to be damaged by ultraviolet rays, and the fabric has no care effect on the skin. Summary of the invention

[0004] The purpose of the present invention is to provide an anti-ultraviolet skin care fabric doped with rare earth elements and a preparation method thereof in order to solve the problems raised in the above background technology.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] An anti-ultraviolet skin care fabric doped with rare earth elements, comprising an anti-ultraviolet layer and a skin care layer;

[0007] The anti-ultraviolet layer is woven from polyester fibers in warp and weft;

[0008] The skin care layer is woven from skin care silk threads, which are composited from rare earth fibers, silk fibers, jute fibers and milk protein fibers. The rare earth fibers are obtained by adding nano-cerium oxide, gypsophila extract and pterygium wilfordii extract into a spinning solution.

[0009] The anti-UV layer is used to protect against direct sunlight, and the skin care layer is used for direct contact with the skin.

[0010] Nano-cerium oxide crystals are rare metals with a stable structure. When scavenging free radicals, only the valence state of cerium ions is converted without any change in the crystal structure. Therefore, they can scavenge free radicals in a long-lasting manner and enhance the vitality of skin cells.

[0011] Silk is mainly composed of animal protein and is rich in eighteen kinds of amino acids essential to the human body. It can promote the vitality of skin cells and prevent vascular sclerosis. Long-term use can prevent skin aging. It has a special antipruritic effect on certain skin diseases and has a certain health care effect on arthritis, periarthritis of the shoulder, and asthma.

[0012] Milk protein fibers are fine, tender and smooth, with softness and skin-friendliness equal to or better than cashmere; they are breathable, moisture-conductive and refreshing; their warmth retention is close to that of cashmere, and they have good warmth retention; their wear resistance, pilling resistance, coloring and strength are all better than cashmere; because milk protein contains amino acids, the skin will not reject this fabric, which is equivalent to a layer of human skin and has a nourishing effect on the skin.

[0013] Preferably, the mass ratio of the nano cerium oxide, spinning solution, Glechoma longituba extract and Pterocephalus chinensis extract is 1:10:3:4.

[0014] Preferably, the spinning solution is prepared by mixing polyamide and hexafluoroisopropanol.

[0015] Preferably, the preparation method of the Herba Cynoglossifoliae extract is as follows:

[0016] S1: Wash and dry the fresh golden iron lock, and then crush it into 300-400 meshes to obtain golden iron lock powder;

[0017] S2: putting the powder obtained in S1 into an ultrasonic extraction tank, adding ethanol, immersing at room temperature, and ultrasonically extracting to obtain a filtrate;

[0018] S3: The filtrate is repeatedly extracted with ether and then with n-butanol, separated by a silica gel column, eluted in the order of chloroform, methanol and water, and finally the eluate is separated and purified by a Lober Rp-8-Merck column. During purification, the eluate is eluted in the order of eluent, methanol and water. Finally, the eluate is concentrated under reduced pressure to obtain the extract of the golden iron lock.

[0019] Preferably, the preparation method of the Pterocephalus chinensis extract is as follows:

[0020] S1: washing and drying the coarse powder of Pterocephalus chinensis, and crushing the powder into Pterocephalus chinensis powder;

[0021] S2: extract the powder of Pterocephalus truncatus by reflux extraction with 80% ethanol for 3 times, each time for 1 hour, and recover the ethanol under reduced pressure to obtain a concentrated solution;

[0022] S3: The concentrate was extracted with petroleum ether, chloroform and water-saturated n-butanol in sequence to obtain the Pterocephalum extract.

[0023] The extract of Cyperus rotundus and the extract of Pterocephalus chinensis enter the fabric and can adhere to the skin when it comes into contact with the skin, playing a moisturizing and water-locking effect, effectively reducing the skin's water loss and playing a skin care effect.

[0024] A method for preparing the anti-ultraviolet skin care fabric doped with rare earth elements as described above comprises the following steps:

[0025] S1: Add nano cerium oxide, gypsophila extract and pterygium wilfordii extract into the spinning solution and mix and stir, obtain rare earth fiber through wet spinning process, and then weave rare earth fiber, silk fiber, jute fiber and milk protein fiber into skin care silk thread; spinning solution refers to the concentrated solution of fiber-forming polymer, solution spinning is to dissolve the fiber-forming polymer in a certain solvent to prepare a spinning solution with a suitable concentration, and then spit the spinning solution from a tiny hole into a coagulation bath or hot gas, the polymer precipitates into solid filaments, and the finished fiber can be obtained through the process of stretching - shaping - washing - drying. For silk fiber, jute fiber and milk protein fiber that can be directly made into fiber, no spinning solution needs to be added, and for nano cerium oxide, gypsophila extract and pterygium wilfordii extract that cannot be directly made into fiber, they need to be added to the spinning solution before being made into fiber.

[0026] S2: Weaving a skin care layer using the skin care thread in S1;

[0027] S3: Using polyester fiber warp and weft weaving to obtain an anti-ultraviolet layer;

[0028] S4: Compounding the skin care layer in S2 and the anti-ultraviolet layer in S3 to obtain a skin care fabric.

[0029] The beneficial effects of the present invention are:

[0030] The present invention provides an anti-ultraviolet skin care fabric doped with rare earth elements, which can not only effectively block ultraviolet rays and prevent ultraviolet rays from irradiating the skin, but also utilize the special effects produced by the special structure of rare earth elements and special extracts to protect the skin, with stable and lasting effects, so that the skin can still maintain vitality under ultraviolet rays and reduce the speed of skin aging.
