Description

[0001] This application claims the priority of the Chinese patent application filed with the China Patent Office on November 1, 2024, with application number 202411552322.7 and application name “A method for manufacturing false eyelashes”, the entire contents of which are incorporated by reference in this application. Technical Field

[0002] The invention relates to the technical field of false eyelash manufacturing, and in particular to false eyelashes and a manufacturing method thereof. Background Art

[0003] As a beauty product, false eyelashes are an important part of makeup. With the improvement of economy, people's demand for beauty has become stronger, and the market demand for false eyelashes has also increased significantly.

[0004] However, the current manufacturing of false eyelashes generally relies on cumbersome manual production. Each link of the false eyelashes, such as pressing, combining, root cleaning, and thread combining, requires a lot of manual participation, resulting in low production efficiency and high requirements for manual operation accuracy. The yield rate is low, which limits the expansion of the scale of false eyelash production and makes it difficult to meet the current market demand for false eyelashes.

[0005] At the same time, false eyelashes are usually composed of hair and stems. The hair is used to determine the style and shape of the false eyelashes, and the stems determine the product quality of the false eyelashes and the wearing comfort of consumers. Therefore, if there is a problem with either the hair or the stems during the production process, it will affect the quality of the finished false eyelashes.

[0006] For example, during the hair pressing process, manual operation is required to ensure that the hair material is evenly bonded and firmly bonded, or during the root cleaning process, the operator must ensure that the roots are cleaned without damaging the hair material, which requires high manual skills of the operator. For another example, the existing false eyelashes need to bond the hair material to the stem line, and the glue used for bonding may greatly limit the appearance and wearing comfort of the false eyelashes. Summary of the invention

[0007] The purpose of the present invention is to solve the problem that the existing false eyelash manufacturing process consumes labor costs and has low production efficiency. The present invention provides a method for manufacturing false eyelashes, which can produce an integrally formed false eyelash product with high production efficiency.

[0008] In order to solve the above technical problems, the embodiment of the present invention discloses a method for manufacturing false eyelashes, comprising:

[0009] Laser printing: hollowing out the pre-designed false eyelashes by laser;

[0010] Obtain an integrated semi-finished false eyelash product.

[0011] According to another specific embodiment of the present invention, the clustered false eyelashes include multiple clustered false eyelashes, the integrally formed false eyelash semi-finished product includes multiple false eyelash semi-finished products, and the manufacturing method of the false eyelashes further includes:

[0012] Ultrasonic welding is used to weld the plurality of false eyelash semi-finished products into one body.

[0013] According to another specific embodiment of the present invention, the laser printing includes ultraviolet laser printing.

[0014] An embodiment of the present invention discloses a method for manufacturing false eyelashes, comprising:

[0015] providing a substrate;

[0016] Processing a pre-designed false eyelash design pattern on the substrate by a non-heat-applying processing method; wherein the false eyelash design pattern includes: a hair material group pattern and a base pattern, and the hair material group pattern is connected to the base pattern;

[0017] False eyelashes are obtained; wherein the false eyelashes include: a hair material group and a base, and the hair material group is connected to the base.

[0018] By adopting the above technical scheme, firstly, the false eyelashes produced by the manufacturing method of false eyelashes in the embodiment of the present application have a base integrally formed with a plurality of hair material groups, which can omit the traditional cumbersome processes such as hair pressing, hair combining, root cleaning, and line combining. In other words, there is no need for manual hair pressing, hair combining, root cleaning, and line combining, which reduces labor costs and effectively improves the production efficiency of false eyelashes.

[0019] Secondly, in the traditional manufacturing process, it is necessary to manually evenly stick each strand of hair material to the mold to obtain a single piece of semi-finished false eyelashes. Such single-piece semi-finished false eyelashes cannot be used directly as finished products, but need to be further manually fixed to the base (such as the stem line) (this process is a traditional thread joining process) to obtain a finished false eyelash that can be directly attached to the bottom of the human eyelashes. Moreover, the above process requires high accuracy of manual operation.

[0020] However, the manufacturing method of the embodiment of the present application can directly process the one-piece false eyelashes on the substrate by a non-heat-applying processing method. Therefore, there is no need for traditional hair pressing, hair joining, and thread joining, and the production efficiency is higher. Moreover, the manufacturing method of the embodiment of the present application does not require operation accuracy, and the yield rate is higher.

[0021] Furthermore, the manufacturing method of the embodiment of the present application adopts a non-heat-applying processing method to manufacture false eyelashes. During the entire manufacturing process, the material of the base material of the false eyelashes will not be affected, and a better processing effect can be produced.

[0041] An embodiment of the present invention discloses a method for manufacturing false eyelashes, comprising:

[0042] providing a substrate;

In other words, there is no need for manual hair pressing, hair combination, root cleaning, and line closing, which reduces labor costs and effectively improves the production efficiency of the first false eyelashes.

[0048] Secondly, in the traditional manufacturing process, it is necessary to manually evenly stick each strand of hair material to the mold to obtain a single piece of semi-finished false eyelashes. Such single-piece semi-finished false eyelashes cannot be used directly as finished products, but need to be further manually fixed to the base (such as the stem line) (this process is a traditional thread joining process) to obtain a finished false eyelash that can be directly attached to the bottom of the human eyelashes. Moreover, the above process requires high accuracy of manual operation.

[0049] However, the manufacturing method of the embodiment of the present application can directly process the first false eyelashes formed in one piece on the substrate by a non-heat-applying processing method. Therefore, there is no need for traditional hair pressing, hair joining, and thread joining, and the production efficiency is higher. Moreover, the manufacturing method of the embodiment of the present application does not require operation accuracy, and the yield rate is higher.

[0050] Furthermore, multiple first false eyelashes can be stacked and connected along the thickness direction through ultrasonic welding or bonding technology to obtain at least one second false eyelash, that is, the second false eyelash has a multi-layer structure, thereby providing more design possibilities and flexibility for the production of false eyelashes.

For ordinary technicians in this field, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0112] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0113] The present application provides a method for manufacturing false eyelashes. The method for manufacturing false eyelashes in the embodiment of the present application aims to ensure that the false eyelashes are integrally formed, thereby breaking the existing traditional manual process to improve production efficiency. Moreover, the false eyelashes manufactured by the method for manufacturing false eyelashes in the embodiment of the present application have the advantages of being environmentally friendly, light, and highly comfortable.

[0114] To facilitate understanding of the technical solution of the present application, some concepts or terms involved in the present application are first explained.

[0115] (1) Warpage

[0116] The curl of false eyelashes refers to the degree of curvature of false eyelashes, usually expressed in degrees. Specifically, taking one of the hairs of false eyelashes as an example, the curl refers to the angle between the arc tangent of the curved part of the hair and the horizontal line. This angle determines the curl of the false eyelashes, that is, the curl.

[0117] In addition, the horizontal line is a theoretical reference line, which is used to provide a benchmark for describing the curling. Those skilled in the art can understand that the horizontal line can represent the plane where the roots of the false eyelashes are placed when wearing false eyelashes, or can represent a straight line parallel to the ground.

[0118] (2) Embossing

[0119] Embossing is also called pneumatic embossing process or pneumatic mold pressing process, which refers to the process of layering the hair material of false eyelashes using pneumatic molds (such as pneumatic press knife, but not limited to this). This process includes two important factors: air pressure and pressing. Pressing means that the false eyelashes are pressed into an uneven layered effect by physical pressure, so that the false eyelashes have a visual layered effect, which is more three-dimensional and fluffy. Air pressure is used to control and adjust the force applied by the pneumatic press knife to the false eyelashes, and is also the power source for driving the pneumatic press knife.

[0120] The two factors of compression and air pressure complement each other to achieve a layered effect on the false eyelashes, which can also be described as blooming, that is, the hair of the false eyelashes spreads outward from the roots, and each hair no longer points in the same direction, thus making the false eyelashes more three-dimensional as a whole, similar to the petals of a flower spreading outward.

[0121] refer to Figure 1 and Figure 2The existing manual hair pressing is the primary link in the production of false eyelashes. The main function of the steps is to use manual and various styles of hair pressing molds to process the standard bundled hair raw materials through molds of various shapes, and manually integrate them together. A large amount of manual production makes the production of false eyelashes mainly rely on a large amount of manual production, which makes the processing efficiency slow. In the subsequent process, about 70% of the hair needs to be manually trimmed to clean the excess parts. Finally, cotton thread or fish silk thread and the prepared polyurethane glue are needed to bond them together. It can be found that a lot of labor is consumed in the entire modern process and chemical reagents are used for bonding.

[0122] The purpose of developing this patented technology is to reduce the manual steps in the production of false eyelashes and get rid of the use of chemical reagents.

[0123] The new process uses a purple laser marking machine and ultrasonic welding as the core processing technology. The processing is fast and easy, eliminating a large number of manual production steps, and using mechanical equipment to complete the one-piece molding of the false eyelash production process.

[0124] Purple laser marking machine

[0125] UV laser marking machine is a product in the laser marking machine series and is also a newly developed laser processing technology. Because the traditional laser marking machine uses laser thermal processing technology, the room for improvement in precision is limited. However, the UV laser marking machine uses a cold processing method, so the precision and thermal impact are minimized, which is a major leap in laser technology.

[0126] UV laser processing is called cold processing because the high-energy molecules of ultraviolet photons directly detach the molecules on the metal or non-metallic materials that need to be processed. However, this detachment causes the molecules to separate from the material. This working method does not generate heat. Since this type of processing does not generate high heat, it is different from traditional lasers.

[0127] On the basis of cold processing, the effect of processing product materials will get better results and better development. When using cold laser processing, the probability of material influence is reduced to one percent, so that the advantages of its processing are fully utilized, which is also a major improvement in laser technology. I believe that in the future laser market, ultraviolet lasers will gradually be widely used.

[0128] The specific process is as follows:

[0129] First, use CAD drawing software to distribute several designed false eyelash shapes within a certain size, such as 200mm*200mm, and prepare several PVE (polyvinyl ethyl ether) plastic films of a certain thickness, such as 0.05mm, with a specific size of 300mm*200mm. Transfer the designed false eyelash drawing data into the Ziguang laser printer, calibrate XYZ for printing, and laser hollow out several false eyelash shapes, and the process is completed.

[0130] The plastic solidifies naturally, and when the plastic film is peeled off, several or a piece of false eyelashes formed in one piece are obtained. At this time, the several or a piece of eyelashes can be removed from the plastic film with a knife.

[0131] In some possible implementations, the embodiments of the present application may also use stereolithography (SLA), selective laser sintering (SLS), etc. for laser printing to produce semi-finished false eyelashes. The embodiments of the present application do not impose specific restrictions on this. As long as laser printing is used to obtain the semi-finished false eyelashes, it falls within the protection scope of the embodiments of the present application.

[0132] Next we use ultrasonic technology to carry out the following processing technology.

[0133] How Ultrasound Works

[0134] Principle of ultrasonic welding: When ultrasonic waves act on the contact surface of thermoplastic plastics, they will generate high-frequency vibrations of tens of thousands of times per second. This high-frequency vibration with a certain amplitude transmits ultrasonic energy to the welding area through the upper weldment. Since the acoustic resistance of the welding area, i.e. the interface between the two welds, is large, local high temperature will be generated. Due to the poor thermal conductivity of plastics, it cannot be dissipated in time for a while, and gathers in the welding area, causing the contact surface of the two plastics to melt rapidly. After a certain pressure is applied, it is fused into one. When the ultrasonic wave stops working, the pressure is allowed to continue for a few seconds to solidify and form, thus forming a strong molecular chain to achieve the purpose of welding, and the welding strength can be close to the strength of the raw materials. The quality of ultrasonic plastic welding depends on three factors: the amplitude of the transducer welding head, the applied pressure and the welding time. The welding time and welding head pressure can be adjusted, and the amplitude is determined by the transducer and the amplitude rod. There is an appropriate value for the interaction of these three quantities. When the energy exceeds the appropriate value, the amount of plastic melted is large and the weld is easy to deform; if the energy is small, it is not easy to weld firmly, and the applied pressure cannot be too large. The pressure can be determined based on the actual force-bearing area, material, number of welds, etc., such as the length, width, thickness and other factors of the welded part. The optimal pressure is the product of the length of the welded part and the optimal pressure per 1 mm of the edge. For example, in the actual production process, the optimal pressure value within the unit size can be determined first, and then combined with the weld length or area size, the overall optimal pressure can be calculated comprehensively.

[0135] Ultrasonic specific process

[0136] By using the ultraviolet laser marking machine, we have obtained false eyelash semi-finished products in bunches or pieces. We use the principle of ultrasonic welding to weld the false eyelash semi-finished products in bunches or pieces together. After this process, a single piece of false eyelash semi-finished product becomes a superimposed combination of multiple semi-finished products, which increases the amount of false eyelashes and the changes in styles several times, and also meets the needs of various consumer groups of false eyelashes.

[0137] High temperature setting

[0138] The production process is as follows: Place a certain specification of high-humidity cotton paper such as 13g on the designated position on the operating table and ensure that the paper is laid flat on the table and scrape off excess water. Place 1-2 semi-finished products that have been pressed and formed on the designated position of the cotton paper. Use the corresponding specification of the aluminum alloy hollow rod to hold the cotton paper and the aluminum alloy hollow rod at the lower end of the cotton paper with both hands and roll vertically to the upper end of the operating table until the upper end of the cotton paper is rolled. Finally, put the rolled false eyelashes aluminum alloy hollow rods in batches into a high-temperature steamer or a drying and sterilization box, adjust the temperature to 110℃-180℃, and the time is 60min-120min. After heating, turn off the power and naturally cool in the box to about 23℃ in the room temperature, then take out the aluminum alloy hollow rods in batches from the box. Finally, the workers manually take out the fixed false eyelashes from the aluminum alloy hollow rods.

[0139] Embossing process

[0140] The so-called embossing process is to turn a single-curl false eyelash into a multi-layer messy appearance. After high-temperature shaping, we get a single-curl false eyelash. Use a pneumatic pressure knife to aim at the position of 0.5mm-3mm on the stem line of the false eyelashes and cut vertically. The size of the air pressure determines the size of the flowers of the same style. The greater the air pressure, the greater the multi-layer effect of the same style of false eyelashes. Different knives determine the different flowering effects. Usually, there are flat knives, serrated knives, and wavy knives. Each prop corresponds to a flowering effect. Finally, the hair material of the false eyelashes also plays a different flowering effect. Usually, false eyelashes are divided into PET (polyethylene terephthalate) and PBT (polybutylene terephthalate). PET is a hard plastic relative to PBT, and the size of the flower is often larger than that of PBT material, while the flowering effect of PBT is often more natural and beautiful.

[0141] Package

[0142] Finally, packaging is carried out.

[0143] The manufacturing method of the false eyelashes of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0144] [Example 1]

[0145] refer to Figure 3 and Figure 4 , Figure 3 A flow chart of a method for manufacturing false eyelashes in an embodiment of the present application is shown. Figure 4 The schematic diagram of the product packaging of false eyelashes in the embodiment of the present application is exemplarily shown, wherein: Figure 4 Any one of the false eyelashes 10 is made by the above-mentioned manufacturing method.

[0146] refer to Figure 3 and Figure 5The manufacturing method of false eyelashes provided in the embodiment of the present application comprises the following steps:

[0147] S100: providing a substrate 110 .

[0148] In this step, a substrate 110 required for manufacturing false eyelashes is selected and prepared.

[0149] Illustratively, the embodiment of the present application does not impose any specific limitation on the number of substrates 110 . For example, one, two, four, five, or other number of substrates 110 may be prepared, and the selection may be made based on actual application.

[0150] In some possible implementations, the substrate 110 required for the embodiment of the present application includes, but is not limited to: polymers such as plastic film, rayon film, and nylon film.

[0151] The plastic film includes, but is not limited to, polyethylene (PE) film, polyethylene terephthalate (PET) film, polypropylene (PP) film, polyurethane (PU) film, polyvinyl ether (PVE) film, and the like.

[0152] Among them, polyethylene (PE) film and polypropylene (PP) film are light and flexible; polyethylene terephthalate (PET) film has good toughness; polyurethane (PU) film is soft and durable; polyvinyl ethyl ether (PVE) film has good adhesion and durability, and is more easily degraded.

[0153] Similarly, the rayon film has a texture similar to that of natural eyelashes, and using the rayon film as the substrate 110 can provide a more natural appearance and a more comfortable wearing experience. The nylon film has good elasticity and strength, and using the nylon film as the substrate 110 can provide higher durability and wearing comfort.

[0154] In this step, a polyvinyl ether (PVE) plastic film 111 with a thickness of 0.05 mm and a size of 300 mm*200 mm is selected as the substrate 110, but it is not limited thereto. Any of the above-mentioned types of plastic films or materials such as rayon films and nylon films can also be selected. Any of the above-mentioned types of plastic films or rayon films and nylon films can also be selected. For example, three substrates 110 are provided in the same batch of manufacturing, two of which can be selected from any of the above-mentioned types of plastic films, and the other substrate 110 can be selected from rayon films or nylon films. In addition, the thickness and size of the selected substrate 110 can also be selected according to actual applications. The following text uses the above-mentioned polyvinyl ether (PVE) plastic film 111 as an example for explanation.

[0155] refer to Figure 3 and Figure 6 After executing step S100, start executing step S200.

[0156] S200: Processing a pre-designed false eyelash pattern 210 on the substrate 110 by a non-heat-applying processing method.

[0157] Based on the above step S100, Figure 6 As shown, in this step, two pre-designed false eyelashes design patterns 210 are processed on the polyvinyl ethyl ether (PVE) plastic film 111 provided in the above step S100 by a non-heat-applying processing method.

[0158] It can be seen that the design pattern 210 of the false eyelashes includes: a connected hair material group pattern 211 and a base pattern 212. In this step, the polyvinyl ethyl ether (PVE) plastic film 111 is processed along the outline of the design pattern 210 of each false eyelash (that is, the outline of the multiple hair material group patterns 211 and the base pattern 212) by a non-heat-applying processing method.

[0159] It should be noted that the wool group graphic 211 and the base graphic 212 of the embodiment of the present application include but are not limited to the following design methods. As long as the design methods ensure that the wool group graphic 211 and the base graphic 212 do not fall off after being processed on the substrate 110 by a non-heat-applying processing method, they all fall within the protection scope of the embodiment of the present application and can be selected according to the needs of consumers.

[0160] refer to Figure 6 and Fig. 7A , Fig. 7A Exemplary illustration Figure 6 In some possible implementations, Fig. 7A Three wool material group graphics 211 and a base graphic 212 are shown, each wool material group graphic 211 includes at least one wool material graphic 2111 (in Fig. 7A In the figure, each wool material group graphic 211 includes six wool material graphics 2111, but is not limited thereto). It can be seen that the three wool material group graphics 211 are connected to the same base 212, that is, multiple wool material group graphics 211 can correspond to the same base graphic 212.

[0161] Further, Fig. 7AThe six wool material graphics 2111 of each wool material group graphic 211 shown are divided into three groups (but not limited to three groups, for example, one group, two groups, four groups, etc.), each group includes two wool material graphics 2111 (not limited to two, for example, each group can include one, three, four wool material graphics 2111), and the two wool material graphics 2111 in each group cross each other (but not limited to crossing, for example, they can be spaced from each other). In addition, it can be seen that each wool material graphic 2111 is in an arc shape, but can also be in a straight line shape, a wavy shape, etc., and the embodiment of the present application does not limit this. At the same time, the base graphic 212 is rectangular, but can also be in an arc shape (the arc of the arc can be, for example, a arc that is convenient for fitting the eyelids), a semicircular shape, a circular shape, etc.

[0162] refer to Figure 7B In some possible implementations, the design pattern 210 of the false eyelashes in the embodiment of the present application can also be designed to include three hair material group patterns 211 and two base patterns 212. Figure 7B As shown, two wool material group graphics 211 are connected to the same base graphic 212 , and another wool material group graphic 211 is connected to another base graphic 212 .

[0163] Specifically, refer to Figure 7B Combined with Figure 6 In this design, since there are intersections (such as Figure 7B Therefore, even if the two base patterns 212 are spaced apart from each other, after processing along the contours of the three wool group patterns 211 and the base pattern 212 on the polyvinyl ethyl ether (PVE) plastic film 111 without applying heat, the formed false eyelashes are still one-piece formed (as described later). In this way, under the premise of ensuring that the one-piece formed false eyelashes can be obtained, the weight of the obtained false eyelashes is relatively reduced, reducing the wearing burden of the user.

[0164] In addition, this design method can be understood as that a plurality of wool material group graphics 211 can correspond to a plurality of base graphics 212 , and the number of the wool material group graphics 211 is greater than the number of the base graphics 212 .

[0165] refer to Figure 7C In some possible implementations, the design pattern 210 of the false eyelashes of the embodiment of the present application can also be designed to include three hair material group patterns 211 and three base patterns 212. It can be seen that the three hair material group patterns 211 correspond to the three base patterns 212 one by one, that is, in this design mode, multiple hair material group patterns 211 correspond to multiple base patterns 212 one by one.

[0166] and Figure 7BThe same is that, due to the special process of processing the design pattern 210 of false eyelashes on the polyvinyl ethyl ether (PVE) plastic film 111 without applying heat, the embodiment of the present application provides Figure 7C In the design shown, the three wool group graphics 211 are cross-connected (refer to Figure 7C The dotted line frame S shown as an example), then the formed false eyelashes are still one-piece formed (as described later). Moreover, the weight of the obtained false eyelashes can be further reduced, further reducing the wearing burden of the user.

[0167] refer to Fig.7D In some possible implementations, the design pattern 210 of the false eyelashes in the embodiment of the present application can also be designed to include three hair material group patterns 211 and five base patterns 212. Fig.7D As shown, it can be seen that one wool group graphic 211 can be connected to two base graphics 212 , and similarly, another wool group graphic 211 can also be connected to two base graphics 212 , and the last wool group graphic 211 is connected to one base graphic 212 .

[0168] That is to say, in this design, it can be understood that a plurality of wool material group graphics 211 can correspond to a plurality of base graphics 212 , and the number of wool material group graphics 211 is less than the number of base graphics 212 .

[0169] refer to Fig. 7E In some possible implementations, the design pattern 210 of the false eyelashes of the embodiment of the present application can also be designed as: including a hair material group pattern 211 and a base pattern 212, wherein the hair material group pattern 211 includes at least two hair material patterns 2111 (in Fig. 7E In the figure, the wool material group pattern 211 includes six wool material patterns 2111, but is not limited thereto), and it can be seen that the wool material group pattern 211 is connected to a base 212. That is to say, in this design, the wool material group pattern 211 and the base pattern 212 correspond one to one.

[0170] For example, Fig. 7EThe six wool material graphics 2111 of a wool material group graphic 211 shown are also divided into three groups (but not limited to three groups, for example, it can be one group, two groups, four groups, etc.), each group includes two wool material graphics 2111 (not limited to two, for example, each group can include one, three, four wool material graphics 2111), and the two wool material graphics 2111 in each group cross each other (but not limited to crossing, for example, they can be spaced from each other). In addition, it can be seen that each wool material graphic 2111 is in an arc shape, but it can also be in a straight line shape, a wavy shape, etc., and the embodiment of the present application does not limit this. At the same time, the base graphic 212 is rectangular, but it can also be in an arc shape (the arc of the arc can be, for example, a arc that is easy to fit the eyelid), a semicircular shape, a circular shape, etc.

[0171] refer to Figure 7F In some possible implementations, the design graphic 210 of the false eyelashes of the embodiment of the present application can also be designed to include: a hair material group graphic 211 and three base graphics 212 arranged at intervals, that is, one hair material group graphic 211 corresponds to multiple base graphics 212.

[0172] Specifically, it can be seen that some of the wool patterns 2111 in the wool group pattern 211 cross each other. Since the wool group pattern 211 is processed on the polyvinyl ethyl ether (PVE) plastic film 111 by a non-heat-applying processing method, after the wool group pattern 211 itself is processed, the wool group formed by it will not be scattered (i.e., cross-connected). At the same time, the bases obtained by processing the three spaced-apart base patterns 212 will not fall off through the cross-connected wool groups, that is, an integrally formed false eyelash can be obtained. Moreover, in the design method in which a wool group pattern 211 corresponds to multiple base patterns 212, Figure 7F The multiple base graphics 212 shown are spaced apart from each other, which can also reduce the weight of the false eyelashes obtained, further reducing the wearing burden of the user.

[0173] refer to Figure 7G In some possible implementations, the design pattern 210 of the false eyelashes of the embodiment of the present application can also be designed as: including a hair material group pattern 211 and three base patterns 212, wherein the hair material group pattern 211 includes at least two hair material patterns 2111 (in Figure 7G In the embodiment, the wool material group graphic 211 includes six wool material graphics 2111, but is not limited thereto). It can be seen that the wool material group graphic 211 can be connected to any one of the three base graphics 212. For example, Figure 7GIn the embodiment, the one wool material group graphic 211 is connected to the base graphic 212 located in the middle, and no other wool material group graphic 211 is designed at the two base graphics 212 located on both sides. In this design, it can be understood that one wool material group graphic 211 can correspond to multiple base graphics 212, and the one wool material group graphic 211 can be connected to any one of the multiple base graphics 212.

[0174] refer to Figure 7H , in some possible implementations, Figure 7H Three wool group graphics 211 and one base graphic 212 are shown. Different from the above design, the wool graphics 2111 in each wool group graphic 211 have no intersections, and there are no intersections between adjacent wool group graphics 211. Then in this design, the three wool group graphics 211 need to be connected to one base graphic 212. That is, in this design, multiple wool group graphics 211 are connected to one base graphic 212.

[0175] refer to Fig.7I , in some possible implementations, Fig.7I A wool group graphic 211 and a base graphic 212 are shown. Fig.7I The wool material pattern 2111 in the wool material group pattern 211 shown has no intersection. In this design mode, a wool material group pattern 211 corresponds to and is connected to a base pattern 212.

[0176] In addition, the embodiment of the present application does not impose any specific restrictions on the shape of the base graphic 212. For example, the base graphic 212 can be rectangular, but can also be elliptical, semicircular, circular, arc-shaped, etc., and can be selected according to the actual application scenario.

[0177] For example, refer to Figure 7J In some other possible implementations, a wool material group pattern 211 and a base pattern 212 may also be designed, and the wool material group pattern 211 includes only one wool material pattern 2111. This design method is similar to the above Fig. 7E The design shown is similar (i.e., one wool group graphic 211 corresponds to one base graphic 212), except that the number of wool graphics 2111 in the wool group graphic 211 is different, and, Figure 7J The base pattern 212 is shown to be circular, so that consumers can easily attach the resulting false eyelashes to the natural eyelashes of the eyelid (eg, graft eyelashes).

[0178] For another example, one wool group graphic 211 and a plurality of (for example, two) base graphics 212 may be designed, wherein the one wool group graphic 211 also includes only one wool graphic 2111, and the shape of the base graphic 212 is convenient for consumers to attach.

[0179] In some possible implementations, the above-mentioned non-heat-applying processing method includes: a non-heat-applying laser printing process. Exemplarily, the non-heat-applying laser printing process includes: ultraviolet laser printing or photocuring 3D printing.

[0180] It should be noted that, in the embodiment of the present application, the laser printing process without applying heat means that heat is not applied to the polyvinyl ethyl ether (PVE) plastic film 111 and the design pattern 210 of the false eyelashes thereon, and printing is performed on the basis of cold processing. It can also be understood as a laser printing process that does not generate high heat, that is, a small amount of heat may be generated during the laser printing process, but this small amount of heat will not affect the material and processing effect of the polyvinyl ethyl ether (PVE) plastic film 111 and the false eyelashes 10, which is different from traditional laser printing. It can be understood that this small amount of heat will not cause thermal damage to the above-mentioned plastic film, rayon film, and nylon film. As long as it is within the heat range that will not cause thermal damage to the above-mentioned substrate, it belongs to the protection scope of the embodiment of the present application.

[0181] Continue to refer Figure 3 and Figure 6 After executing step S200, start executing step S300.

[0182] S300: Obtain false eyelashes 10.

[0183] Based on the above step S200, in this step, if Figure 6 As shown, the two integrally formed false eyelashes 10 can be obtained by peeling off the polyvinyl ether (PVE) plastic film 111. It can be seen that the peeled polyvinyl ether (PVE) plastic film 111 has two hollow parts corresponding to the two false eyelashes 10 (such as Figure 6 (shown by the dashed line).

[0184] Further, in this step, each false eyelash 10 includes: a plurality of hair material groups 11 and a base 12, and it can be seen that the plurality of hair material groups 11 (for example Figure 6 The three hair material groups 11 shown in the figure are connected to the base 12, and the multiple hair material groups 11 of the false eyelashes 10 obtained correspond one-to-one with the multiple hair material group patterns 211 mentioned above, and the base 12 of the false eyelashes 10 obtained corresponds one-to-one with the base pattern 212 mentioned above.

[0185] That is to say, in the first embodiment, the false eyelashes 10 are of a single-layer structure. Figure 4 and Figure 6As shown, each false eyelash 10 corresponds to a design pattern 210 of a single false eyelash.

[0186] Based on this, reference Figure 4 Combined with Figure 6 The embodiment of the present application further provides a false eyelash 10, each false eyelash 10 is manufactured by the false eyelash manufacturing method of the above-mentioned steps S100 to S300.

[0187] It can be seen that each false eyelash 10 of the embodiment of the present application corresponds to a design pattern 210 of a false eyelash, and each false eyelash 10 includes: a plurality of hair material groups 11 and a base 12, wherein each hair material group 11 includes at least one hair, and the plurality of hair material groups 11 and the base 12 are integrally formed by a non-heat-applied processing method, and at least a portion of the plurality of hair material groups 11 protrudes from the base 12.

[0188] It should be noted that the base of the embodiment of the present application can be understood as a component similar to a stem in the traditional sense, or it can be understood as a part or position used to be attached to the bottom of the natural eyelashes of the human eye. As long as the false eyelashes 10 can be attached to the natural eyelashes of the human eye and the hair material group 11 can be integrally formed in a position, it falls within the protection scope of the base 12 of the embodiment of the present application.

[0189] For example, the plurality of integrally formed false eyelashes 10 may be fixed on the surface of the eyelash extension device 10 by means of the adhesive strip 20. Figure 4 In the packaging box 30 shown, a complete set of false eyelashes product can be obtained.

[0190] The specific implementation of the above step S200 will be described in detail below with reference to the accompanying drawings.

[0191] refer to Figure 8 and Fig. 9 In some possible implementations, the above step S200 at least includes:

[0192] Step S201: Obtain design software.

[0193] In this step, a graphic design software for the design pattern 210 of false eyelashes is selected. The graphic design software has graphic design and image editing functions.

[0194] For example, you can choose any one of computer-aided design (CAD), Photoshop image processing software, CorelDRAW graphic design software, etc. The present application embodiment does not make any specific restrictions on this. As long as the design software can design false eyelash design graphics, it belongs to the protection scope of the present application embodiment. Fig. 9 The CAD computer-aided design software shown is described as an example.

[0195] Step S202: Divide at least one design area S of at least one false eyelash design graphic 210 based on the drawing size of the design software.

[0196] Based on the above step S201, in this step, based on the CAD computer-aided design software, a drawing with a size of, for example, 200 mm*200 mm is selected, and two design areas S corresponding to the design graphics 210 of two false eyelashes are divided in the drawing area. For example, a design area S of 100 mm*200 mm is reserved for the design graphics 210 of the two false eyelashes respectively.

[0197] The embodiment of the present application does not impose any specific restrictions on the size of the drawing of the CAD computer-aided design software and the size of the design area S into which the design graphic 210 of each false eyelash is divided.

[0198] Step S203: designing the outline of the corresponding false eyelash design pattern 210 in at least one design area S.

[0199] like Fig. 9 As shown, based on the above step S202, in this step, the outlines of the corresponding false eyelash design patterns 210 are drawn in the above two reserved 100mm*200mm design areas S, thereby completing the pre-design of the false eyelash design patterns 210.

[0200] In some possible embodiments, further combined Fig. 10A and Fig. 10B According to the foregoing, in the embodiment of the present application, the outline of the design pattern 210 of the false eyelashes can be designed as follows Figure 6 and Fig. 9 As shown in the sheet, or designed as Fig. 10A The strip shown, or designed as Fig. 10B The embodiment of the present application does not specifically limit the shape of the design pattern 210 of the false eyelashes, and can be selected according to actual application requirements. In this embodiment, the design pattern 210 is as follows: Figure 6 and Fig. 9 The two false eyelash design patterns 210 shown are provided as examples for illustration.

[0201] In addition, according to the foregoing, in the first embodiment, each false eyelash 10 corresponds to a design pattern 210 of a single false eyelash. In other words, the design idea of ​​the design pattern 210 of the false eyelash can be drawn based on the fact that the false eyelash 10 is a single-layer structure. It can be seen that each design pattern 210 of the false eyelash corresponds to a single-layer structure of the false eyelash 10. Therefore, the design patterns 210 of the multiple false eyelashes do not need to be unified. In other words, in the design process of the same batch, the sizes, shapes, and density of the hair materials of the design patterns 210 of the multiple false eyelashes can be different, but can also be kept the same. The embodiment of the present application does not limit this.

[0202] For example, the embodiment of the present application does not limit the number of hair material group patterns 211 of the design pattern 210 of false eyelashes, and the number of hair material roots in each hair material group pattern 211, and can be selected according to actual application requirements.

[0203] Meanwhile, illustratively, the width and length of the outline of each hair material group graphic 211 of the design graphic 210 of the false eyelashes and the width and length of the outline of the base graphic 212 can be arbitrarily selected and designed according to actual needs.

[0204] Exemplarily, the wool material profile in the wool material group pattern 211 can be straight or curved. Exemplarily, the profile of the base pattern 212 can be straight (e.g. Fig. 9 , Fig. 10A , Fig. 10B The base pattern 212 may be a straight line as shown in FIG. 9 , or may be a curved pattern (for example, the curved base pattern 212 as shown in FIG. 9A ), and this embodiment of the present application does not impose any specific limitation on this.

[0205] Step S204: placing the substrate into a laser printing device that does not apply heat.

[0206] refer to Figure 8 Combined with Figure 5 and Figure 6 In this step, firstly, a laser printing device capable of realizing a laser printing process without applying heat is selected, and then the polyvinyl ethyl ether (PVE) plastic film 111 is placed in the laser printing device (not shown in the figure).

[0207] In some possible implementations, the above-mentioned laser printing process without applying heat in the embodiment of the present application adopts ultraviolet laser printing. In this step, an ultraviolet laser printer (not shown in the figure) can be exemplarily selected as the laser printing device.

[0208] UV laser printing is a cold processing laser printing process, which mainly processes the surface of the polyvinyl ether (PVE) plastic film 111 through high-energy UV photons. Such high-energy photons can break the chemical bonds of the molecules on the surface of the polyvinyl ether (PVE) plastic film 111, so that these molecules are separated from the surface of the polyvinyl ether (PVE) plastic film 111, thereby achieving the printing effect. Since the photon energy of the UV laser is high, it can generate a higher energy density in a smaller area. These higher energy densities act on the polyvinyl ether (PVE) plastic film 111 mainly through photochemical action rather than thermal action, so during the entire printing process, the temperature around the polyvinyl ether (PVE) plastic film 111 will not rise.

[0209] The ultraviolet laser printing process used in the embodiments of the present application is different from the traditional laser printing process.

[0210] Specifically, firstly, as can be seen from the foregoing, the UV laser printing process will not apply heat to the design pattern 210 of the false eyelashes, and thus will not affect the polyvinyl ethyl ether (PVE) plastic film 111 and the material of the printed false eyelashes 10, and the probability of material influence is effectively reduced.

[0211] Secondly, the UV laser printer used in the UV laser printing process is a device that uses UV laser for printing. Since the UV laser has a short wavelength and a thin beam, it is particularly suitable for printing precision objects such as false eyelashes, which have many styles, different thicknesses and densities of hair materials, and require high precision. At the same time, no chemical reagents are required during the printing process, and less volatile organic compounds are generated, so it is more environmentally friendly.

[0212] In addition, the ultraviolet laser printer is fast and suitable for mass production. Therefore, on the basis of replacing the traditional cumbersome manual production and directly and efficiently printing out the one-piece false eyelashes 10, the production efficiency can be further improved.

[0213] In some possible implementations, the above-mentioned laser printing process without applying heat in the embodiment of the present application can also be laser printed using stereolithography (SLA) to produce semi-finished false eyelashes. The embodiment of the present application does not impose any specific restrictions on this. As long as the process of obtaining false eyelashes by a processing method without applying heat is used, it falls within the protection scope of the embodiment of the present application.

[0214] Step S205: Transmitting data of at least one false eyelash design pattern 210 to a non-heat-applying laser printing device.

[0215] refer to Figure 8 and Fig.11In this step, the data of the designed pattern 210 of the false eyelashes is transmitted to an ultraviolet laser printer (not shown in the figure).

[0216] Exemplarily, the data of the above-mentioned design graphic 210 of the false eyelashes include but are not limited to: CAD computer-aided design software drawing information (for example, a size of 200mm*200mm), contour information of the design graphic 210 of the false eyelashes (for example, the width and length of the contours of the hair material group 211 and the base 212 of the design graphic 210 of the false eyelashes), the thickness, size, quantity, etc. of the polyvinyl ethyl ether (PVE) plastic film 111.

[0217] Step S206: Setting printing parameters and calibrating the non-heat-applying laser printing device.

[0218] refer to Figure 8 and Fig.11 In this step, the printing parameters of the UV laser printer are set and the XYZ axis calibration is performed.

[0219] Exemplarily, the above printing parameters include, but are not limited to: substrate type, ultraviolet laser power, printing speed, ultraviolet laser pulse frequency, etc.

[0220] Step S207: hollowing out at least one false eyelash in one piece on the substrate by laser according to the data using a laser printing device without applying heat.

[0221] refer to Figure 8 and Fig.11 In this step, two integrally formed false eyelashes 10 are laser-hollowed out on the polyvinyl ethyl ether (PVE) plastic film 111 using an ultraviolet laser printer according to the data of the design pattern 210 of the false eyelashes in the above step S205.

[0222] refer to Fig. 12A and Figure 6 In some possible implementations, the above step S300 further includes:

[0223] Step S301: non-heating shaping of false eyelashes;

[0224] In this step, the two false eyelashes designed patterns 210 hollowed out by laser in the above step S200 are subjected to non-heating setting. It should be noted that in the embodiment of the present application, non-heating setting refers to a setting method that does not require the application of heat, that is, no heating operation is used in the entire non-heating setting process.

[0225] For example, room temperature setting can be used. Specifically, soak the special tissue paper with chemical reagents, place the tissue paper at a designated position on the operating table and ensure that the paper is laid flat on the table and scrape off excess chemical reagents, then place two false eyelashes 10 at the designated position on the tissue paper, use a rod body of corresponding size specifications (such as an aluminum alloy hollow rod, and for example, a solid rod of other materials, which is not limited in the embodiment of the present application) to pinch the tissue paper and the rod body at the lower end position above the tissue paper with both hands and roll vertically toward the upper end of the operating table until it rolls over the upper end of the tissue paper, and then the operation is completed, and the two false eyelashes 10 are left to stand for 24 hours. After the chemical reagent and the two false eyelashes 10 are fully reacted, the operator takes out the two fixed false eyelashes 10 from the aluminum alloy hollow rod.

[0226] In some possible implementations, a high-temperature shaping method can also be used, for example, the curled false eyelashes are placed in a high-temperature steamer or a drying and sterilizing box, the temperature is controlled at 40°C to 140°C, and after heating for a certain period of time (for example, 60min-120min), the false eyelashes are naturally cooled to room temperature, and finally the operator takes the two shaped false eyelashes 10 out of the stick. Exemplarily, the above temperature can be adjusted to, for example, 40°C, 67.5°C, 99.2°C, 118°C, 123.7°C, 139°C, 140°C, etc.

[0227] Step S302: Obtaining curled false eyelashes.

[0228] Based on the above step S301, in this step, two false eyelashes 10 with curling can be directly obtained after non-heating shaping.

[0229] That is, after the false eyelashes 10 are shaped without heating, the hairs in the multiple hair material groups 11 in the false eyelashes 10 are curled and shaped by the rod body, so that the false eyelashes 10 with a certain degree of curling can be obtained. The embodiment of the present application does not limit the degree of curling, and the degree of curling is determined by the size specifications of the rod body.

[0230] The size specifications of the rod body at least include: the diameter of the round rod body and the contact surface of the special-shaped rod body.

[0231] That is to say, when a round rod is used, the curl of the false eyelashes 10 is determined by the diameter of the round rod. For example, if the length of the hair material of the obtained false eyelashes 10 is 16 mm, a 12 mm rod can be selected to obtain a certain curl of the false eyelashes 10; and if a greater curl is to be obtained, the diameter of the rod can be reduced, such as a rod with a diameter of 10 mm or 8 mm. For another example, if the length of the hair material of the obtained false eyelashes 10 is 14 mm, a rod with a diameter of 11 mm can be selected, but the embodiment of the present application does not limit this.

[0232] When a special-shaped rod is used, for example, a spiral rod, the curling degree of the false eyelash 10 is determined by the contact surface between the false eyelash 10 and the spiral rod. The spiral pitch, number of spiral turns, and shape of the spiral rod are different, and the contact surface for the false eyelash 10 to contact is also different accordingly. Therefore, the degree of curvature generated by the false eyelash 10 after contacting the contact surface is also different.

[0233] refer to Fig. 12B and Figure 6 In some other possible implementations, the above step S300 further includes:

[0234] Step S310: performing non-heating shaping on the false eyelashes.

[0235] In this step, the design patterns 210 of the two false eyelashes hollowed out by laser in the above step S200 are fixed without heating.

[0236] It should be noted that in this step S310, the definition and specific shaping process of non-heating shaping are the same as those of the above step S301, and will not be described in detail here.

[0237] Step S320: embossing the false eyelashes after non-heat setting.

[0238] In this step, the false eyelashes after non-heat setting are embossed.

[0239] Specifically, the embossing process can transform two false eyelashes 10 with a single curl into a process with a multi-layer messy appearance effect. After the room temperature setting of the above step S310, two false eyelashes 10 with a single curl can be obtained. At this time, a pneumatic pressing knife is used to align the base 12 of each of the two false eyelashes 10 with a position about 0.5mm-3mm above the base 12, and the knife is cut vertically, so that the hairs in the hair material group 11 of each false eyelash 10 can obtain a blooming effect. It can be understood that a layered effect is generated between the hairs in the hair material group 11, so that the false eyelashes 10 are more three-dimensional and have a sense of hierarchy.

[0240] For example, the air pressure of the pneumatic press knife can determine the size of the flowers of the false eyelashes 10. The greater the air pressure, the greater the multi-layer effect of the false eyelashes 10. For example, the type of pneumatic press knife used can also determine the different flower effects. For example, a flat knife, a serrated knife, a wavy knife, etc. can be used. Each type of pneumatic press knife corresponds to a flower effect.

[0241] It should be noted that the multiple layers of the false eyelashes 10 involved in this step refer to embossing the hair material of the false eyelashes 10 with a single-layer structure to give it a visually multi-layer effect, and does not mean that the false eyelashes 10 have a multi-layer structure.

[0242] Step S330: obtaining false eyelashes with curling and layering.

[0243] Based on the above step S320, in this step, two false eyelashes 10 with curling and layering are obtained after embossing.

[0244] That is to say, after the false eyelashes 10 are shaped without heating, the hair materials in the multiple hair material groups 11 in the false eyelashes 10 are curled and shaped by the rod body, so that the false eyelashes 10 with a certain degree of curling can be obtained.

[0245] Furthermore, the false eyelashes 10 after non-heat setting are embossed, so that the hair material of the false eyelashes 10 is layered.

[0246] It should be noted that, as mentioned above, in the first embodiment, the false eyelashes 10 are of a single-layer structure, that is, multiple hair material groups 211 are located in the same layer structure. The above-mentioned stratification means that the hair materials of the false eyelashes 10 are spread, but the roots of the hair materials are still in the same layer structure, and only the stratified and fluffy effect is achieved visually.

[0247] In addition, for the false eyelashes with a multi-layer structure in the second embodiment described later, stratification means that the hairs of multiple hair material groups (i.e., the first hair material group described later) in each layer structure are diffused, and the roots of the hairs in each layer structure are still in the same corresponding layer, only achieving a layered and fluffy effect visually.

[0248] [Example 2]

[0249] refer to Fig.13 and Fig.14 , Fig.13 The flowchart of the method for manufacturing false eyelashes in the second embodiment of the present application is shown. Fig.14 The schematic diagram of false eyelash product packaging of the second embodiment of the present application is exemplarily shown, wherein: Fig.14 Any one of the false eyelashes (ie, the second false eyelash 50 described below) is manufactured by the above manufacturing method.

[0250] The difference between the second embodiment and the first embodiment is that in the second embodiment, the design patterns of a plurality of false eyelashes need to be processed and further superimposed and connected to form one or more false eyelashes with a multi-layer structure.

[0251] refer to Figures 13 to 15 The manufacturing method of false eyelashes provided in the second embodiment of the present application comprises the following steps:

[0252] S1000: providing a substrate.

[0253] In the second embodiment, step S1000 is the same as step S100 in the first embodiment, and will not be described in detail here.

[0254] S2000: Processing a plurality of pre-designed first false eyelashes design patterns 220 on a substrate by a non-heat-applying processing method.

[0255] In the second embodiment, the only difference between step S2000 and step S200 in the first embodiment is that: in the second embodiment, it is necessary to pre-design a plurality of first false eyelash design patterns 220. In other words, each first false eyelash design pattern 220 cannot be directly sold as a false eyelash after being processed by a non-heat-applying processing method. Therefore, the same parts of step S2000 and step S200 in the first embodiment are not described in detail.

[0256] In this step, if Fig.14 and Fig.15 As shown, each first false eyelash design pattern 220 includes: a plurality of first hair material group patterns 221 and a first base pattern 222 connected to each other.

[0257] S3000: Get multiple first false eyelashes.

[0258] In the second embodiment, the only difference between step S3000 and step S300 in the first embodiment is that in step S3000, each first false eyelash 40 obtained cannot be directly sold as a false eyelash.

[0259] In this step, if Fig.15 As shown, the two first false eyelashes 40 formed in one piece can be obtained by peeling off the polyvinyl ether (PVE) plastic film 111. It can be seen that the peeled polyvinyl ether (PVE) plastic film 111 has two hollow parts corresponding to the two first false eyelashes 40 (such as Fig.15 (shown by the dashed line).

[0260] Further, in this step, each first false eyelash 40 includes: a plurality of first hair material groups 41 and a first base 42. It can be seen that the plurality of first hair material groups 41 (such as Fig.15 The eight first hair material groups 41 shown in the figure are connected to the first base 42. The multiple first hair material groups 41 of each first false eyelash 40 obtained correspond to the multiple first hair material group patterns 221 mentioned above, and the first base 42 of each first false eyelash 40 obtained corresponds to the first base pattern 222 mentioned above.

[0261] Exemplarily, the embodiment of the present application does not limit the number of the first false eyelashes 40. For example, two, three, four, etc. first false eyelashes 40 can be obtained. As long as the number of the first false eyelashes 40 is at least two, it falls within the protection scope of the embodiment of the present application.

[0262] It should be noted that in the second embodiment of the present application, since the design patterns 220 of multiple false eyelashes need to be further superimposed and connected into one or more false eyelashes with a multi-layer structure after processing, the design idea of ​​the design patterns 220 of the false eyelashes can be drawn based on the fact that the false eyelashes are a multi-layer structure. In other words, in the design process of the same batch, the size, shape, and density of the hair material of the design patterns 220 of multiple false eyelashes can be the same or different, and the specific selection needs to be made according to the actual effect after superposition.

[0263] For example, if the first base graphics 222 of the design graphics 220 of two false eyelashes designed in the same batch are the same, and the first wool group graphics 221 are the same, then after being superimposed in the thickness direction, the false eyelashes formed have a multi-layer structure, but the visual sense of hierarchy is poor. For another example, if the first base graphics 222 of the design graphics 220 of two false eyelashes designed in the same batch are the same, and the spacing and distribution density of the first wool group graphics 221 are different, then after being superimposed in the thickness direction, the false eyelashes formed have a multi-layer structure and have a better sense of hierarchy and visual effect. The embodiments of the present application are not limited to this.

[0264] S4000: Superimpose and connect the first bases of the first false eyelashes by ultrasonic welding or bonding.

[0265] refer to Fig.13 , Fig.15 and Fig.16 Based on the above step S3000, in this step, the corresponding two first bases 42 of the two first false eyelashes 40 are overlapped and connected by using ultrasonic welding or bonding technology.

[0266] In some possible implementations, this step S4000 may include:

[0267] The first bases 42 of at least two first false eyelashes 40 among the plurality of first false eyelashes 40 are stacked;

[0268] The first bases 42 of at least two first false eyelashes 40 are fixed by using ultrasonic waves or adhesive materials.

[0269] That is to say, at least two first false eyelashes 40 can be arbitrarily combined and superimposed by using ultrasonic welding or bonding technology.

[0270] For example, if six first false eyelashes 40 are obtained in step S3000, then, illustratively, the two first bases 42 of two of the first false eyelashes 40 may be double-stacked and fixedly connected, the two first bases 42 of another two of the first false eyelashes 40 may be double-stacked and fixedly connected, and the two first bases 42 of the remaining two first false eyelashes 40 may be double-stacked and fixedly connected.

[0271] Alternatively, the three first bases 42 of three of the first false eyelashes 40 may be stacked in three layers and fixedly connected, and the two first bases 42 of the remaining three first false eyelashes 40 may be stacked in three layers and fixedly connected.

[0272] Alternatively, the six first bases 42 of the six first false eyelashes 40 may be stacked and fixedly connected in six layers.

[0273] In some possible embodiments, ultrasonic welding is a process that utilizes high-frequency vibration (ultrasonic waves) to weld plastics or other materials. For example, when ultrasonic waves act on the contact surface of a polyvinyl ether (PVE) plastic film 111 or other polymer film, high-frequency vibrations of tens of thousands of times per second are generated. This high-frequency vibration reaching a certain amplitude transmits ultrasonic energy to the welding area through the upper weldment. Since the welding area, i.e., the interface between the two welds, has a large acoustic impedance, local high temperature will be generated.

[0274] At the same time, due to the poor thermal conductivity of the polyvinyl ethyl ether (PVE) plastic film 111 or other polymer films, the heat cannot be dissipated in time and is accumulated in the welding area, causing the contact surfaces of the two first false eyelashes 40 (i.e., the two first bases 42) to melt rapidly and fuse into one after a certain pressure is applied. When the ultrasonic wave stops acting, the pressure is allowed to continue for a few seconds to solidify and form a solid molecular chain, thus achieving the purpose of welding, and the welding strength can be close to the strength of the raw materials.

[0275] In some possible implementations, in the second embodiment, the first bases 42 of at least two first false eyelashes 40 may also be bonded together using bonding materials.

[0276] For example, based on the design of false eyelashes style and aesthetics, multiple first false eyelashes 40 can be arbitrarily matched to form different styles. According to different style requirements, a chemical reagent with bonding function is applied to the first base 42 of the first false eyelash 40 at a position of about 0.1mm-1mm. The chemical reagent causes a reaction between the raw material films of the multiple first bases 42, thereby achieving the effect of bonding the multiple first false eyelashes 40 together.

[0277] Exemplarily, the chemical reagents of the embodiments of the present application include, but are not limited to: n-butyl cyanoacrylate (n-BCA), polyvinyl alcohol (PVA), and the like, which have bonding functions and do not require application of heat to the bonding objects (i.e., the plurality of first false eyelashes 40).

[0278] For example, n-butyl cyanoacrylate is a fast-curing adhesive, which is used for bonding skin, mucous membranes, plastics, etc. due to its fast bonding speed. Although it is a cyanoacrylate, it is relatively less irritating, but it needs to be used with caution. For example, polyvinyl alcohol is a water-soluble polymer with good bonding properties and water solubility.

[0279] For example, a tape (such as a transparent tape with good adhesion) may be used to adhere to the first base 42 of the first false eyelashes 40 at a position of about 0.1 mm to 1 mm to bond the plurality of first false eyelashes 40 together to achieve a combined effect.

[0280] For another example, glue (such as liquid glue with good adhesion) may be applied to the first base 42 of the first false eyelashes 40 at a position of about 0.1 mm to 1 mm to bond the plurality of first false eyelashes 40 together to achieve a bonding effect.

[0281] For example, it can also be applied to the connection of traditional polyester fiber eyelash filaments, cotton threads, and fish silk threads, that is, the polyester fiber eyelash filaments, cotton threads, and fish silk threads are bonded using chemical reagents, tapes, and glues with bonding functions to ensure that there is no heating process during the entire process.

[0282] It should be noted that the adhesive material of the embodiment of the present application refers to a material used in a processing method without applying heat, that is, when the first base portion 42 is bonded with the adhesive material, no heat is applied to the first false eyelash 40 .

[0283] S5000: Obtain at least one second false eyelash.

[0284] refer to Fig.13 , Fig.15 , Fig.16 and Fig.17A Based on the above step S4000, in this step, a second false eyelash 50 is obtained. The second false eyelash 50 includes: a hair material group 51 and a base 52.

[0285] Among them, Figures 16 to 17B As shown, the base 52 is composed of a plurality of first bases 42 connected in the thickness direction (eg Fig. 17B The hair material group 51 is formed by stacking a plurality of first hair material groups 41 in the thickness direction, and each layer structure in the second false eyelashes 50 corresponds to the first base 42 and the plurality of first hair material groups 41, that is, in the second embodiment, the second false eyelashes 50 are a multi-layer structure, and at the same time, the first base 42 and the plurality of first hair material groups 41 of each layer are integrally formed by a non-heat-applying processing method.

[0286] refer to Fig. 17CIn some possible implementations, in the embodiment of the present application, before the non-heating setting or high-temperature setting is performed, that is, after completing step S4000, at least a portion of the hair material in the hair material group 51 of the second false eyelash 50 is as follows Fig. 17C At this point, it is necessary to further use non-heating setting or high temperature setting (as described above) to bend the wool material.

[0287] refer to Fig.17D In some possible implementations, in the embodiment of the present application, after completing step S4000, at least a portion of the hair material in the hair material group 51 of the second false eyelash 50 has a certain curvature, such as Fig.17D As shown, the wool material can be directly packaged and sold, or it can be further bent and shaped by non-heating shaping or high-temperature shaping. The present application embodiment does not limit this, and it can be selected according to the actual application situation.

[0288] For example, according to the above description, the curl of false eyelashes refers to the degree of curvature of false eyelashes, which is usually expressed in degrees. Fig.17D , you can see Fig.17D The horizontal line B is shown as an example, and the arc tangent line of the curved part of the raw material forms an angle α with the horizontal line B.

[0289] Exemplarily, the tilt of the embodiment of the present application can be selected from any one of the tilts, such as baby bend (i.e., angle α is 15°), J tilt (i.e., angle α is 30°), B tilt (i.e., angle α is 40°), C tilt (i.e., angle α is 50°), D tilt (i.e., angle α is 60°), D++ tilt (i.e., angle α is 75°), LU (Last Up, also called right-angle tilt, i.e., angle α is approximately 90°), and L wide angle (i.e., angle α is 165°).

[0290] like Fig.14 As shown, for example, the plurality of second false eyelashes 50 can be fixed on the surface of the eyelash extension device 20 by means of the adhesive strip 20. Figure 4 In the packaging box 30 shown, a complete set of false eyelashes product can be obtained.

[0291] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above is a further detailed description of the present invention in conjunction with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
