Abstract
Description
Technical Field
[0001] This invention belongs to the field of facial mask fabric technology, specifically relating to a peach blossom fiber moisturizing mask fabric and its preparation method. Background Technology
[0002] Hydrating mask sheets, as the core carrier of facial mask products, are widely used in daily skincare, problem skin repair, and post-operative skin soothing. Their core function is to carry skincare essence and adhere closely to the skin to achieve moisture replenishment, nutrient delivery, and long-lasting release of active ingredients, meeting consumers' diverse skincare needs such as moisturizing, anti-aging, and brightening. They occupy an important position in the beauty and skincare industry.
[0003] Existing hydrating mask sheets can basically meet daily beauty needs, but some mask sheets rely solely on a single cellulose matrix, lacking natural skincare ingredients, or although they contain active ingredients, they use a simple mixing process, resulting in poor loading and binding of effective ingredients. This leads to uneven distribution of ingredients, weak bonding with fibers, low release efficiency, and difficulty in fully exerting skincare effects. At the same time, they lack environmental performance. Many mask sheets use non-renewable raw materials or contain synthetic additives, resulting in high energy consumption during the production process. They are also difficult to degrade naturally after use, easily causing environmental burden. Therefore, it is necessary to design a peach blossom fiber hydrating mask sheet and its preparation method. Summary of the Invention
[0004] The purpose of this invention is to provide a simple and reasonably designed peach fiber moisturizing membrane fabric and its preparation method in order to solve the above problems.
[0005] The present invention achieves the above objectives through the following technical solutions: A peach blossom fiber moisturizing membrane cloth, wherein the peach blossom fiber moisturizing membrane cloth is composed of peach blossom fiber, which is prepared by compounding peach blossom extract and plant cellulose. The components of peach blossom fiber include quercetin, quercetin, kaempferol, tridecanedioic acid, 1,6-dehydrated-β-D-glucose and cellulose.
[0006] As a further optimization of the present invention, the contents of quercetin, quercetin, kaempferol, tridecanoic acid, 1,6-dehydro-β-D-glucose and cellulose are respectively: 400-600 mg / kg of quercetin, 300-500 mg / kg of quercetin, 200-300 mg / kg of kaempferol, 100-300 mg / kg of tridecanoic acid, 800-1200 mg / kg of 1,6-dehydro-β-D-glucose, and the remainder is cellulose.
[0007] A method for preparing a peach blossom fiber moisturizing membrane fabric includes the following steps: S1: peach blossom screening; S2: raw material washing; S3: raw material drying; S4: pulverization; S5: active ingredient extraction; S6: concentration; S7: extracting; S8: spray drying; S9: fiber cake making; S10: loading into vat; S11: fiber pretreatment; S12: fiber compounding; S13: washing; S14: dehydration; S15: drying and molding. S1: Select fresh, mold-free, pest-free, and uniformly colored peach blossoms, and remove withered leaves, impurities, and broken petals to ensure the purity and effective ingredient content of the raw materials; S2: Place the selected peach blossoms in deionized water and rinse them 3-4 times using a running rinse method to remove surface dust, dirt and residual pollutants, and drain the surface water. S3: Place the washed peach blossoms into a constant temperature drying oven, control the temperature at 60-70℃, and dry them until the moisture content is ≤5%, so that the peach blossoms are dry and crisp, making them easier to crush later. S4: The dried peach blossoms are fed into a high-speed pulverizer and pulverized into powder of 80-100 mesh to increase the specific surface area of the raw material and improve the subsequent extraction efficiency. S5: Add an aqueous ethanol solution to the peach blossom powder and perform extraction; S6: Combine multiple extracts and use a vacuum concentration process to obtain a high-concentration peach blossom extract; S7: Continuously concentrate the extract to a thick paste to form peach blossom extract, ensuring a high concentration of active ingredients; S8: Send the peach blossom extract into a spray dryer, control the inlet air temperature to 170-190℃ and the outlet air temperature to 70-90℃, and after drying, obtain a dry, loose peach blossom extract powder for later use. S9: Select renewable plant cellulose as the matrix raw material and press it into uniform fiber cakes using a cake press machine; S10: The pressed fiber cake is loaded into a sealed reaction cylinder, deionized water is added to submerge the fiber cake, and then the sealed cylinder is soaked. S11: Add sodium hydroxide aqueous solution to the reaction vessel for pretreatment; S12: Peach blossom extract is mixed with pretreated cellulose and then compounded. S13: Place the fiber composite material in a cleaning device and rinse it with deionized water 3-4 times to remove uncomposite free extracts, residual salts and impurities, and ensure fiber purity. S14: The cleaned fiber composite material is fed into a centrifugal dewatering machine and dewatered at 3000 r / min for 15-20 min. The moisture content of the material after dewatering is controlled to be 30%-40%, which is convenient for subsequent drying. S15: The dehydrated fiber composite material is placed in a constant temperature oven and dried at 60-70℃ until the moisture content is ≤8%, which enhances the stability and flexibility of the fiber structure. After drying, the fiber is combed and opened to obtain peach fiber with both physical flexibility and skin care effect. Then, it is made into peach fiber moisturizing membrane cloth by web laying and needle punching.
[0008] As a further optimization of the present invention, in step S5, the concentration of the ethanol aqueous solution is 60%-80%, and the ethanol aqueous solution is added to the peach blossom powder at a solid-liquid ratio of 1:5-8. During the extraction process, the mixture is placed in a reflux extraction device and extracted at a constant temperature of 50-60℃ 2-3 times, with each extraction lasting 2-3 hours, to fully dissolve the effective flavonoid components such as quercetin, peach quercetin, and kaempferol.
[0009] As a further optimization of the present invention, in step S6, the specific parameters of the vacuum concentration process are a vacuum degree of 0.06-0.08 MPa and a concentration temperature of 45-55℃; during the concentration process, the mixture is continuously stirred at a stirring speed of 200 r / min, and finally concentrated to 1 / 5-1 / 4 of the original extract volume.
[0010] As a further optimization of the present invention, in step S9, the selected renewable plant cellulose is viscose fiber or Tencel fiber, with a fiber diameter of 10-20 μm. After being cut to a length of 1-3 cm, it is fed into a hydraulic pressing machine, with the pressing pressure controlled at 5-8 MPa and the pressing time at 3-5 min, to press into a uniform fiber cake with a diameter of 10-15 cm and a thickness of 2-3 cm, and the density of the fiber cake is 0.3-0.5 g / cm³. 3 .
[0011] As a further optimization of the present invention, in step S10, the volume of the sealed reaction cylinder is 2-3 times the total volume of the fiber cake to ensure that the fiber cake has sufficient reaction space in the cylinder; the added deionized water needs to be purified in advance to make the conductivity ≤10μS / cm to avoid impurities in the water affecting the fiber pretreatment effect. After the deionized water submerges the fiber cake by 1-2cm, the cylinder is sealed and nitrogen is introduced to replace the air in the cylinder to prevent the fiber from being oxidized and degraded in the subsequent pretreatment process. Then, after sealing, it is left to stand for 10-15min to allow the fiber cake to be fully moistened with water.
[0012] As a further optimization of the present invention, in step S11, the concentration of sodium hydroxide aqueous solution is 2% during the pretreatment process. The addition of sodium hydroxide aqueous solution requires adjusting the pH of the system to 10-11. Then, the fiber is soaked at 30-35℃ for 30 minutes to soften and activate it. Subsequently, it is rinsed multiple times with deionized water until neutral, and the water is drained to obtain pretreated cellulose, thereby improving the composite ability of fiber and extract.
[0013] As a further optimization of the present invention, in step S12, the peach blossom extract powder prepared in step S8 is added to the pretreated cellulose at a mass ratio of peach blossom extract to pretreated cellulose of 1:8-12, and an appropriate amount of deionized water is added at the same time. The solid-liquid ratio of the added deionized water is 1:3-5. Then, the mixture is stirred and compounded at 300 r / min at 30-40℃ for 30-60 min, so that the effective components in the peach blossom extract are fully combined with the cellulose to form a uniform fiber composite material.
[0014] As a further optimization of the present invention, in step S15, the thickness of the net during net laying is 0.1-0.3 mm, and the net laying density is 20-30 g / m². 2 When acupuncture is performed using a needle punching machine, the needle density of the machine is 300-400 needles / cm². 2 The needle-punching depth is 5-8mm. Through needle-punching, the fibers can interweave to form a stable network structure.
[0015] The beneficial effects of this invention are as follows: This invention uses renewable plant cellulose such as viscose fiber and Tencel fiber as a matrix, combined with natural peach blossoms as raw materials. The resulting membrane fabric is an environmentally friendly material that is biodegradable and has a high liquid absorption rate. The production process employs mature technologies such as reflux extraction, spray drying, and centrifugal dehydration, effectively shortening the production cycle and reducing energy consumption and raw material loss. Furthermore, the readily available raw materials make it suitable for large-scale mass production. Simultaneously, through a specific composite process, peach blossom extract is deeply integrated with renewable plant cellulose, achieving a triple advantage of high content of natural skincare ingredients, excellent physical properties, and good environmental performance. This maximizes the retention of natural flavonoids such as quercetin, quercetin, and kaempferol in peach blossoms, thereby exerting highly effective moisturizing, antioxidant, spot-fading and brightening, and anti-aging repair effects. It improves dry and rough skin, reduces wrinkles, and enhances the skin's disease resistance. Moreover, all effective ingredients are derived from natural peach blossom extract, without any synthetic additives, ensuring higher safety in use. Attached Figure Description
[0016] Figure 1 This is a flowchart of the preparation method of the present invention. Detailed Implementation
[0017] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0018] Please see Figure 1 A method for preparing a peach fiber moisturizing membrane fabric includes the following steps: S1: Peach blossom screening: Select fresh, mold-free, pest-free, and uniformly colored peach blossom raw materials. Manually remove impurities such as withered leaves, stones, and dust, as well as damaged or browned petals to ensure the purity of the raw materials and ensure the stable content of effective components extracted later. S2: Raw material washing: Place the screened peach blossoms in a deionized water washing tank and wash them continuously 4 times using a flowing rinsing method, with each rinse lasting 8 minutes, to thoroughly remove dust, dirt and residual pollutants attached to the surface of the peach blossoms. After rinsing, drain the surface water to avoid excess water affecting the subsequent drying efficiency. S3: Raw material drying: Place the washed and drained peach blossoms flat into a constant temperature drying oven, set the oven temperature to 70℃, and continue drying until the peach blossom moisture content is ≤5%, so that the peach blossoms are dry and crisp, which makes it easier to form uniform powder in the subsequent crushing process, while avoiding moisture residue that may cause the raw materials to mold. S4: Crushing process: The dried peach blossoms are fed into a high-speed crusher. The screen mesh size of the crusher is adjusted to crush the peach blossoms into a uniform powder of 100 mesh. By increasing the specific surface area of the raw material, the extraction efficiency of the subsequent effective components is improved. After crushing, the peach blossom powder is collected in a sealed container for later use. S5: Extraction of active ingredients: Add 80% ethanol aqueous solution to peach blossom powder, with the addition ratio controlled at a solid-liquid ratio (mass-volume ratio of peach blossom powder to ethanol aqueous solution) of 1:8; place the mixture in a reflux extraction device, set the extraction temperature to 60℃, and extract at a constant temperature 3 times, with each extraction lasting 3 hours. After each extraction, separate the extract and filter residue by filtration to fully dissolve flavonoid active ingredients such as quercetin, peach quercetin, and kaempferol; S6: Concentration treatment: Combine all extracts and process them using a vacuum concentration process, setting the vacuum degree to 0.08MPa and the concentration temperature to 55℃; during the concentration process, continuously stir at a speed of 200r / min to prevent local overheating and coking of the extract, and finally concentrate to 1 / 5-1 / 4 of the original extract volume to obtain a high-concentration peach blossom extract. S7: Extract Processing: The high-concentration peach blossom extract is placed in the concentration device and continuously concentrated under reduced pressure until the extract forms a thick paste-like peach blossom extract. This ensures that the effective components such as quercetin and peach quercetin are highly enriched, thereby increasing the efficacy concentration of the subsequent extract powder. S8: Spray drying: Send the peach blossom extract into the spray dryer, set the inlet air temperature to 190℃ and the outlet air temperature to 90℃, and convert the extract into dry, loose peach blossom extract powder through spray drying. After collection, seal and store in a cool, dry place for later use to avoid moisture absorption and deterioration. S9: Fiber Cake Making: Select viscose fiber or Tencel fiber (fiber diameter 10-20μm) as the renewable plant cellulose matrix raw material, cut it to a length of 1-3cm, and feed it into a hydraulic cake press; set the pressing pressure to 8MPa and the pressing time to 5min, and press it into cakes with a diameter of 10-15cm, a thickness of 2-3cm, and a density of 0.3-0.5g / cm³. 3 The uniform fiber cake ensures air permeability and pretreatment uniformity during subsequent cylinder loading. S10: Loading into the cylinder: Load the pressed fiber cake into a sealed reaction cylinder, the volume of which is 3 times the total volume of the fiber cake; add purified deionized water (conductivity ≤10μS / cm) into the cylinder, ensuring that the deionized water submerges the fiber cake by 1-2cm; after sealing the cylinder, purge the air in the cylinder with nitrogen gas of ≥99.9% purity to prevent fiber oxidation and degradation, then seal and let stand for 15min to allow the fiber cake to be fully moistened with water; S11: Fiber pretreatment: Add a 2% sodium hydroxide aqueous solution to a sealed reaction tank and adjust the pH of the system to 11; keep the temperature inside the tank at 35℃ and soak for 30 minutes to soften and activate the fiber. Then drain the alkaline solution and rinse the fiber cake with deionized water several times until neutral. After draining the water, the pretreated cellulose is obtained, which enhances the composite ability of the fiber and peach blossom extract. S12: Fiber Composite: Peach blossom extract powder prepared in S8 was added to pretreated cellulose at a mass ratio of 1:12 (peach blossom extract to pretreated cellulose); an appropriate amount of deionized water was added at the same time, and the solid-liquid ratio of deionized water to pretreated cellulose was controlled to be 1:5; the mixture was placed in a constant temperature water bath at 40℃ and stirred at 300r / min for 60min to fully combine the effective components in the peach blossom extract with the cellulose to form a uniform fiber composite material. S13: Cleaning treatment: Transfer the fiber composite material to the cleaning device and rinse it with deionized water 4 times, each rinse lasting 5 minutes, to thoroughly remove uncomposite free extracts, residual salts and impurities, ensure fiber purity and avoid impurities affecting the final performance of the membrane. S14: Dehydration treatment: The cleaned fiber composite material is sent to a centrifugal dehydrator, the speed is set to 3000 r / min, and the dehydration time is 20 min; during the dehydration process, a filter with a pore size of 50 μm is used to prevent fiber loss, and the moisture content of the material after dehydration is finally controlled to be 30%-40%, which reduces the energy consumption of subsequent drying and avoids the fiber from becoming brittle due to excessive dryness. After dehydration, the composite material is broken up to remove clumps. S15: Drying and Shaping: The dehydrated fiber composite material is placed in a constant temperature drying oven at 70℃ and dried until the moisture content is ≤8%, enhancing the structural stability and flexibility of the fiber. The dried fiber is then carded into a single fiber state by a carding machine, and then opened by an opening machine to obtain fluffy and uniform peach blossom fiber. Subsequently, it is fed into a web-laying machine, controlling the web thickness to be 0.1-0.3mm and the web density to be 20-30g / m². 2 Finally, the needles are shaped by a needle punching machine, with a needle density set at 300-400 needles / cm. 2 The needle-punching depth is 5-8mm, which makes the fibers intertwine to form a stable mesh structure, thus producing peach fiber moisturizing membrane fabric.
[0019] A peach fiber moisturizing membrane fabric prepared through the above steps is composed of peach fiber, which includes quercetin, quercetin, kaempferol, tridecanedioic acid, 1,6-dehydrated-β-D-glucose, and cellulose. The contents of quercetin, quercetin, kaempferol, tridecanedioic acid, and 1,6-dehydrated-β-D-glucose are as follows: 587 mg / kg of quercetin, 470 mg / kg of quercetin, 288 mg / kg of kaempferol, 108 mg / kg of tridecanedioic acid, and 1147 mg / kg of 1,6-dehydrated-β-D-glucose.

S6: Concentration treatment: Combine all extracts and process them using a vacuum concentration process, setting the vacuum degree to 0.06MPa and the concentration temperature to 48℃; during the concentration process, stir continuously at a speed of 200r / min to prevent local overheating and coking of the extract, and finally concentrate to 1 / 5 of the original extract volume to obtain a high-concentration peach blossom extract. S7: Extract Processing: The high-concentration peach blossom extract is placed in the concentration device and continuously concentrated under reduced pressure until the extract forms a thick paste-like peach blossom extract. This ensures that the effective components such as quercetin and peach quercetin are highly enriched, thereby increasing the efficacy concentration of the subsequent extract powder. S8: Spray drying: Send the peach blossom extract into a spray dryer, set the inlet air temperature to 175℃ and the outlet air temperature to 75℃, and convert the extract into dry, loose peach blossom extract powder through spray drying.

[0023] A peach fiber moisturizing membrane fabric prepared through the above steps is composed of peach fiber, which includes quercetin, quercetin, kaempferol, tridecanoic acid, 1,6-dehydrated-β-D-glucose, and cellulose. The contents of quercetin, quercetin, kaempferol, tridecanoic acid, and 1,6-dehydrated-β-D-glucose are as follows: 478 mg / kg of quercetin, 415 mg / kg of quercetin, 287 mg / kg of kaempferol, 114 mg / kg of tridecanoic acid, and 1089 mg / kg of 1,6-dehydrated-β-D-glucose.
[0024] The performance of the peach fiber moisturizing membrane fabric obtained in the above embodiments was verified, and compared with existing membrane fabric products on the market, as shown in Table 1 below: Table 1 Based on the above, this invention uses renewable plant cellulose such as viscose fiber and Tencel fiber as a matrix, combined with natural peach blossoms as raw materials. The resulting membrane fabric is an environmentally friendly material that is biodegradable and has a high liquid absorption rate. The production process employs mature technologies such as reflux extraction, spray drying, and centrifugal dehydration, effectively shortening the production cycle and reducing energy consumption and raw material loss. In addition, the raw materials are readily available, making it suitable for large-scale mass production. Furthermore, through a specific composite process, peach blossom extract is deeply integrated with renewable plant cellulose, achieving a triple advantage of high content of natural skincare ingredients, excellent physical properties, and good environmental performance. This maximizes the retention of natural flavonoids such as quercetin, quercetin, and kaempferol in peach blossoms, thereby exerting highly effective moisturizing, antioxidant, spot-fading and brightening, and anti-aging repair effects. It improves dry and rough skin, reduces wrinkles, and enhances the skin's disease resistance. Moreover, all effective ingredients are derived from natural peach blossom extract, without any synthetic additives, making it safer to use.
