Description

Technical Field

[0001] The invention relates to the technical field of facial mask cloth manufacturing, and in particular to a preparation method of a ginkgo fiber facial mask cloth. Background Art

[0002] Facial mask cloth is a common carrier of facial mask essence, which is usually made of non-woven fabric. The current facial mask cloth itself does not have the function of maintaining the skin, and usually needs to be used with facial mask essence, that is, the facial mask cloth absorbs the facial mask essence and is applied to the skin surface, and the facial mask essence is used to achieve the effects of nourishing the skin, moisturizing the skin, and whitening the skin; and if the facial mask cloth is directly soaked in water and then attached to the skin surface (that is, water is used instead of facial mask essence), the facial mask cloth separated from the facial mask essence does not have the effects of nourishing the skin, moisturizing, and whitening. That is, the facial mask cloth is only a carrier of the facial mask essence, and the facial mask cloth itself does not have any skin maintenance effect. The effect of the mask depends entirely on the facial mask essence. The existing facial mask cloth body is relatively simple, and the facial mask cloth itself lacks the effect of maintaining the skin. Summary of the invention

[0003] In order to solve the above problems of the facial mask cloth in the prior art, the present invention provides a method for preparing a ginkgo fiber facial mask cloth. The facial mask cloth prepared by the method can be used directly after being moistened with water, and has good skin moisturizing, anti-oxidation and antibacterial effects; and can also be used in conjunction with a facial mask essence.

[0004] In order to achieve the above object, the present invention adopts the following technical solution: A method for preparing a ginkgo fiber mask cloth comprises the following steps: S1. Preparation of main fiber web: prepare the main fiber materials according to the following weight parts: 8-20 parts of viscose fiber and 6-10 parts of ginkgo fiber. The above fibers are mixed, opened and combed into the main fiber web; S2: Preparation of auxiliary fiber web: prepare auxiliary fiber materials according to the following weight parts: 2-4 parts of bamboo fiber and 5-10 parts of viscose fiber, mix and loosen the above fibers and then comb them into auxiliary fiber web, and lay the auxiliary fiber web on the upper surface of the main fiber web; S3: Hot rolling: The main fiber web and the auxiliary fiber web laid together are pulled to the hot rolling area for hot rolling, and the non-woven fabric base fabric is obtained after hot rolling; S4: Electrospinning: The nanofiber membrane is formed on the surface of the main fiber web of the non-woven fabric substrate by electrospinning technology; S5: Needle punching: the main fiber web after electrospinning is needle punched to form a non-woven fabric; S6: preparing facial mask cloth: die-cutting the non-woven fabric into a facial mask cloth.

[0005] By adopting the above technical scheme: the mask cloth is directly applied to human skin after being moistened with water; since the main fiber web contains ginkgo fibers, and the ginkgo fibers contain ginkgo leaf extract, the ginkgo leaf extract acts on the skin surface with water, which has an antioxidant protection effect on the skin, and also has many functions such as promoting skin metabolism, moisturizing, anti-inflammatory, firming and whitening the skin, and this mask cloth does not contain any additives, and is safer and more environmentally friendly to use; the main fibers in the auxiliary fiber web have antibacterial effects and can inhibit bacterial growth; the nanofiber membrane has good toughness, high porosity, and is softer, which can improve the fit and comfort with the skin when in contact with the skin.

[0006] Preferably, step S1 further comprises 5-7 parts by weight of high shrinkage polyester fiber. High shrinkage polyester fiber has the property of shrinking as the temperature rises. When the mask cloth acts on the skin, it absorbs the heat of the skin. As the temperature of the mask cloth rises, the mask cloth will gradually shrink and have a shrinkage trend. On the one hand, this shrinkage trend reduces the gaps in the mask cloth and squeezes out the moisture, so that the skin surface has sufficient moisture. On the other hand, the shrinkage trend has a lifting effect on the skin surface, making the skin tighter.

[0007] Preferably, step S2 further comprises 3-5 parts by weight of strong fiber. Strong fiber is a high-performance viscose fiber, and the tensile strength of strong fiber is stronger than that of ordinary viscose fiber, so that the mask as a whole is not easily deformed; especially when the mask cloth absorbs water and expands or shrinks with the increase of temperature, the strong fiber can keep the mask cloth in a relatively stable state.

[0008] Preferably, after step S3, an activated carbon layer is prepared on the surface of the bamboo fiber net of the non-woven fabric base, and the activated carbon layer is arranged between the nanofiber membrane and the non-woven fabric base. The activated carbon layer has the function of absorbing impurities, and dust, oil and other substances precipitated from the skin will be absorbed by the activated carbon layer, thereby making the skin cleaner.

[0009] Preferably, the activated carbon layer is formed by attaching active particles to the surface of a non-woven fabric base fabric through an aqueous environmentally friendly adhesive; the activated carbon particles are made from ginkgo nuts.

[0010] Preferably, the method for preparing activated carbon particles using ginkgo nuts is as follows: a1. Ginkgo nut pretreatment: wash and peel the ginkgo nuts; a2. Carbonization: carbonize the peeled ginkgo nuts in a carbonization furnace in an oxygen-free environment at a carbonization temperature of 400-600°C and a carbonization time of 1.5-3h; a3. Activation: activate the carbonized ginkgo nuts in a carbon dioxide atmosphere at a temperature of 700-850°C and an activation time of 0.3-0.5h to produce ginkgo nut activated carbon; a4. Grinding: grind the ginkgo nut activated carbon to form activated carbon particles with a particle size of 80-220μm.

[0011] Preferably, in step a3, the activated ginkgo activated carbon is cooled in two stages after the activation treatment: the first stage: the ginkgo activated carbon is naturally cooled to 80-90° C. in a room temperature and oxygen-free environment; The second stage: cool the ginkgo activated carbon in a coolant to 20-30℃; the cooled ginkgo activated carbon in the second stage is dried in an oxygen-free environment at a temperature of 45-70℃. The first stage is natural cooling to maintain the porous characteristics of the activated carbon and prevent collapse during the cooling process; the second stage is cooling during cooling to increase the cooling speed.

[0012] Preferably, the cooling liquid contains the following raw materials in parts by weight: 20-28 parts of water, 1-3 parts of ginkgo leaf extract, and 2-5 parts of vitamin C; the temperature of the cooling liquid is 20-30°C. During the second stage cooling process, the ginkgo leaf extract and vitamin C in the cooling liquid will enter the micropores of the ginkgo fruit activated carbon. After drying, the ginkgo leaf extract and vitamin C will remain in the micropores of the ginkgo fruit activated carbon. After the mask cloth is moistened with water, the ginkgo leaf extract and vitamin C will dissolve in the water and act on the skin, thereby further enhancing the efficacy of the mask cloth.

[0013] Preferably, in step a1, the peeled ginkgo nuts are boiled in water for 1-1.5 hours, and the boiled ginkgo nuts are taken out and dried; at the same time, the water used to boil the ginkgo nuts is collected, and the cooling liquid is formed when the water is cooled to 20-30°C. After the ginkgo nuts are made into activated carbon, the various compounds inside them will be decomposed and lose their activity (trace elements such as zinc and selenium will be retained); therefore, the ginkgo nuts are first boiled in water, so that the various substances in the ginkgo nuts (such as flavonoids, terpene lactones and other compounds with pharmacological effects) will dissolve in the water, and the water is used as a cooling liquid. The flavonoids, terpene lactones and other compounds in the water will enter the micropores of the ginkgo nuts activated carbon, and will remain in the micropores of the ginkgo nuts activated carbon after drying. After the mask cloth is moistened with water, the ginkgo leaf extract and vitamin C will dissolve in the water and act on the skin, thereby further enhancing the efficacy of the mask cloth.

[0014] Preferably, in step S4, the method for preparing nanofiber membrane by electrospinning is as follows: b1, freeze-drying and dehydrating ginkgo fiber; b2, grinding the dehydrated ginkgo fiber to a ginkgo nanofiber powder with a particle size of 80-220nm; b3, preparing materials according to the following weight parts: 2-5 parts of ginkgo nanofiber powder, 5-8 parts of polypropylene fiber, and 1-3 parts of ES viscose fiber, stirring and mixing the above materials evenly, preparing a nanofiber net on a non-woven fabric base cloth through an electrospinning device, and then rolling to form a nanofiber membrane. First, the ginkgo fiber is dehydrated and then mechanically ground into ginkgo nanofiber powder, and mixed with polypropylene fiber, and a nanofiber net and a nanofiber membrane are prepared by an electrospinning process; when the nanofiber membrane contacts the skin, it is softer and more comfortable, and the ginkgo nanofiber powder is coated and positioned due to the melting of the polypropylene fiber in the electrospinning, and after the mask cloth is wetted, the active substances in the ginkgo nanofiber powder are dissolved in water and act on human skin.

[0015] Therefore, the present invention has the following beneficial effects: (1) the mask cloth prepared by the process can be directly applied to the skin after being soaked in water, which has the effects of moisturizing the skin, anti-oxidation, antibacterial, and promoting skin metabolism; (2) during use, the activated carbon layer absorbs dust, oil stains, etc. precipitated from the surface of the skin, and at the same time, the ginkgo leaf extract, vitamin C and other substances remaining in the activated carbon particles are dissolved in water and act on the skin; (3) as the contact time between the mask cloth and the skin increases, the temperature of the mask cloth rises, and the high shrinkage polyester fibers in the main fiber web gradually The nanofiber membrane directly contacts the skin and contains ginkgo nanofiber powder. The flavonoids, terpene lactones and other compounds precipitated from the ginkgo nanofiber powder directly act on the surface of the skin, further enhancing the skin's metabolism, moisturizing, and anti-inflammatory effects. (5) No chemical reagents are added during the preparation of all materials in the mask cloth. All materials are processed by mechanical and physical methods. No chemical reagents will remain in the mask cloth, making it safer and more environmentally friendly to use. DETAILED DESCRIPTION
