Description

Technical Field

[0001] The invention discloses an artificial eyelash, and in particular discloses a method for manufacturing the artificial eyelash. Background Art

[0002] Generally speaking, artificial eyelashes refer to eyelashes made from artificial hair or human hair that are used to replace eyelashes or are attached thereto.

[0003] The following is a brief description of a conventional method for manufacturing artificial eyelashes, which includes the following steps: (a) first designing the appearance of artificial eyelashes; (b) attaching artificial hair or human hair and applying glue according to the designed appearance; (c) drying the artificial eyelashes coated with glue and cutting off unnecessary parts; (d) using a rod to roll the artificial eyelashes to form a shape; and (e) attaching the completed artificial eyelashes to a tray and packaging them.

[0004] In the design stage, although it is made in 2D, the product is 3D. In the process of making products, due to human error and deviation caused by unskilled workers, it is preferred to rely on skilled workers for the work. However, the problem is that the number of skilled workers will gradually decrease as time goes by. In addition, the attachment and glue steps require skilled workers to check the design while Figure 1 The raw yarn is attached along the lines of the design drawing. In addition, the cutting step is cut along the reference line after the gluing operation. The winding step is a process that transforms a 2D product into a 3D product. According to the diameter difference of the curled aluminum rod required by the customer, it is divided into J, JC, C, and D curls, and is wound on the rod and heated in a chamber at a temperature of 100-150 degrees. The finished rolled products are classified and attached to the pallet required by the customer to complete the packaging.

[0005] However, in this existing artificial eyelash manufacturing method, it is impossible to confirm the actual product only by drawing design, so skilled people are required to perform re-trim work after the product is completed. In addition, the raw yarn used in the attachment process is packaged in multiple bundles and is difficult to control. That is, the raw yarn is light and thin, and its shape changes with the number of hairs, so it takes more time to work. In addition, the number of raw yarns for a pair of eyelashes is about 150 to 200 bundles. The salary for accurately working on it does not match the effort, which makes the staff unwilling to do this job, so they can only move to countries with low labor costs (Vietnam, Indonesia, etc.).

[0006] As mentioned above, in order to manufacture eyelashes, skilled workers are required to perform the work. Eyelashes are composed of multiple layers (layers), and in order to accurately stack them, the person engaged in the attachment process must have a high level of understanding of the product (attachment takes into account the errors of the production personnel), and it takes a lot of time for unskilled workers to produce the product. In addition, when applying glue, it is necessary to place the laminated semi-finished product on the jig and install the bottom line before applying glue. At this time, bubbles in the glue and the tension of the bottom line will become the cause of product defects.

[0007] Therefore, it is necessary to automate part or all of the manufacturing process in order to shorten the manufacturing process and manufacturing time of artificial eyelashes. Summary of the invention

[0008] The invention relates to a method for manufacturing artificial eyelashes. In order to automate the manufacturing process of artificial eyelashes, the method uses a laser cutting machine to form a cutting line (crack or scratch) on a raw material film and then uses a cutting solution for processing.

[0009] The method for manufacturing artificial eyelashes of the present invention for solving the above-mentioned problem comprises the following steps: using a laser cutting machine to form a cutting line corresponding to the artificial eyelashes on a plastic film having a certain thickness; and depositing the plastic film with the cutting line formed thereon into a cutting solution contained in a cutting container to form the artificial eyelashes; the step of forming the artificial eyelashes allows the end of the plastic film corresponding to the tip of the artificial eyelashes to be deposited in the cutting solution for a relatively long time, thereby sharply forming the tip of the artificial eyelashes.

[0010] The plastic film is a film produced by mixing terephthalic acid, dicarboxylic acid, ethylene glycol, propylene glycol, a flame retardant, a hydrolyzing agent and an antioxidant.

[0011] The cutting solution is one of a sodium hydroxide solution, a calcium hydroxide solution or a potassium hydroxide solution.

[0012] In the step of forming the cutting line, the width of the cutting line is greater than or equal to 0.1 [mm] and less than or equal to 0.2 [mm].

[0013] In the step of forming the artificial eyelashes, the concentration of the cutting solution is 25[%] or more and 40[%] or less.

[0014] In the step of forming the artificial eyelashes, the temperature of the cutting solution is 70 [° C.] or higher and 90 [° C.] or lower.

[0015] In the step of forming the artificial eyelashes, the precipitation time of the plastic film in the cutting solution is 5 [hours] or more and 40 [hours] or less.

[0016] According to the present invention, the plastic film formed with the cutting line (crack or scratch) is deposited into the cutting solution contained in the cutting container, so that the tip of the artificial eyelash is formed sharply, thereby producing artificial eyelashes with sharp tip portions. At this time, the cutting thickness of the tip portion of the artificial eyelashes manufactured by the present invention can be sharpened to 0.01 mm.

[0017] In addition, according to the present invention, uniform products can be produced at any time using manufacturing equipment without relying on skilled personnel, thereby preventing the problem of significant reduction in product quality due to product defects and achieving high-variety and low-volume production.

[0018] In addition, when making semi-finished eyelashes, it is easy to produce insufficient or excessive products due to the difference in ability of each person, and inventory management is difficult, so more operations need to be performed in a manner exceeding the actual order quantity. The present invention adopts equipment manufacturing, which can produce the same product under the same conditions at any time without the need to produce too much semi-finished product inventory, and can also produce multiple varieties in small quantities.

[0027] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] The embodiments of the present invention are provided to more fully illustrate the present invention to those skilled in the art, and the following embodiments may be modified into various other forms, and the scope of the present invention is not limited thereto. Instead, the embodiments are provided to make the present disclosure more substantial and complete, and to fully convey the ideas of the present invention to those skilled in the art.

[0029] The terms used herein are used to illustrate specific embodiments and are not intended to limit the present invention. As used herein, unless the context clearly indicates otherwise, the singular may include the plural. As used herein, the term "and / or" includes any one and all combinations of one or more of the listed terms.

[0030] Figure 1 It is a flowchart for explaining the method for producing artificial eyelashes of the present invention.

[0031] First, a laser cutting machine is used to form a cutting line corresponding to the artificial eyelashes on a plastic film having a certain thickness (step S100). At this time, the width of the cutting line formed by the step of forming the cutting line is greater than 0.1 [mm] and less than 0.2 [mm].

[0032] The plastic film is a sheet material, and is a film produced by mixing terephthalic acid, dicarboxylic acid, ethylene glycol, propylene glycol, a flame retardant, a hydrolyzing agent, and an antioxidant.

[0033] At this time, the composition ratio of each component can be 50-70 weight % of terephthalic acid, 5-30 weight % of ethylene glycol, 5-10 weight % of propylene glycol, 3-10 weight % of hydrolyzing agent, 2-5 weight % of dicarboxylic acid, 0.5-1 weight % of antioxidant and 0.1-3 weight % of flame retardant.

[0034] According to the component ratio of the present invention, that is, compared with the prior art, the present invention reduces the specific gravity of terephthalic acid and increases the specific gravity of ethylene glycol and propylene glycol. At the same time, the component ratio of the antioxidant is reduced by more than two times compared with the prior art, so that the laser cutting machine can easily form cracks or scratches on the plastic film.

[0035] In addition, the plastic film having the composition ratio according to the present invention can be more effectively etched by the cutting solution described later than a general plastic film, and a sharp shape can be obtained at the tip portion of the artificial eyelashes.

[0036] In addition, the artificial eyelashes made of the plastic film according to the component ratio of the present invention can significantly delay the rate of oxidation caused by ultraviolet rays, although the component ratio of the antioxidant is greatly reduced.

[0037] As a device for forming a cut line on a plastic film, a laser cutter or a laser marking machine is used. The types of the laser cutter use optical fiber, carbon dioxide, or ultraviolet laser.

[0038] Figure 2 This is a reference diagram showing the state of actually forming a cutting line on a plastic film using a laser cutting machine. Figure 3 This is an enlarged stereoscopic image of the cutting lines formed on the plastic film by the laser cutting machine.

[0039] The appropriate thickness of the plastic film is 0.05 to 0.1 mm. In order to prevent possible product deformation during laser cutting of the plastic film, a release agent (preferably with an attachment force of 10 to 500 g) may be attached (laminated) to the plastic film for cutting.

[0040] The minimum cutting size (thickness of eyelashes) of laser cutting can reach 0.1mm. The advantage of laser cutting is that it can accurately cut according to the design drawing (made using Auto CAD or Illustator, etc.), but the heat generated during laser cutting will cause the material (plastic film) to burn when the eyelash thickness is less than 0.1mm. Therefore, it is almost impossible to cut eyelashes with a thickness of less than 0.1mm during the first cutting using a laser cutting machine.

[0041] That is, when cutting ultra-thin plastic films with a thickness of 0.05 to 0.1 mm, it is necessary to increase the laser speed (800 to 1500 mm / s) and cut repeatedly to achieve this. If the speed is slow or the laser power is too high, the plastic film will be burned and cannot be used as a product. In addition, when laser cutting is repeated many times, the equipment will have errors. The heat energy generated when the laser beam passes through for cutting makes it possible to burn the material (plastic film) when the thickness of the eyelash is less than 0.1 mm. Cutting with a thickness of less than 0.1 mm for the first time is almost impossible.

[0042] Therefore, although the thickness of artificial eyelashes currently produced varies from 0.03mm to 0.2mm, the thickness of products produced only by laser cutting is 0.1 to 0.2mm, accounting for only about 10 to 20%, so production relying on laser equipment is limited.

[0043] Moreover, the end of the eyelashes gradually narrows (sharp) in more than 90% of the products, so there are limitations in making eyelashes only by laser cutting. Therefore, as described in the present invention, the micro-cutting process is performed using the product width of the target size and the laser beam size.

[0044] The appropriate laser beam size is 0.1 to 0.005 mm. The laser characteristics are used to accurately pass through the designed position, but it cannot cut if it passes through only once. Therefore, the cutting line equivalent to a crack or scratch is formed in the area where the laser beam passes.

[0045] After step S100, the plastic film with the cutting lines formed thereon is deposited into a cutting solution contained in a cutting container to form artificial eyelashes (step S200). At this time, the cutting solution is one of a sodium hydroxide solution, a calcium hydroxide solution or a potassium hydroxide solution.

[0046] The cutting container is a box that holds the cutting solution.

[0047] Figure 4 is a reference diagram showing a cut container.

[0048] Reference Figure 4 The cutting container is in the form of a rectangular hexahedral box (C) with an open top, but this is only an example and can be transformed into any form that can accommodate the cutting solution. In addition, the cutting container can be a cutting container in which two or more support rods (P) that can hold plastic films are arranged in parallel in the horizontal direction. Such support rods (P) can be configured in a manner that can be loaded and unloaded with the cutting container.

[0049] The plastic film is formed with a through hole (H) into which the support rod (P) can be inserted, and the support rod can be inserted through the through hole to be arranged in the cutting container.

[0050] Figure 5a insert Figure 4 In the support rod of the cut container shown, the cut semi-finished products are stacked into multiple layers to form the product shape when making the product.

[0051] The through hole (H) serves as a guide during lamination, so that even an unskilled person can naturally perform alignment with the support rod (P) without being affected by the product understanding. Therefore, the through hole (H) can be used as a basic alignment reference from the product design step.

[0052] is a reference diagram showing a through hole (H) formed in a plastic film, Figure 5b 1 is a reference diagram showing a state in which a support rod of a cut container is inserted into a through hole (H) formed in a plastic film.

[0053] The step of forming the artificial eyelashes allows the end of the plastic film corresponding to the tip of the artificial eyelash to settle in the cutting solution for a relatively long time, thereby sharply forming the tip of the artificial eyelash.

[0054] Figure 6 A reference chart that graphically represents the appropriate concentration, temperature, and precipitation time of a cutting solution for precipitating plastic film.

[0055] Reference Figure 6 , the appropriate concentration of the cutting solution for forming artificial eyelashes may be 25 [%] or more and 40 [%] or less. In addition, the appropriate temperature of the cutting solution for forming artificial eyelashes may be 70 [°C] or more and 90 [°C] or less. In addition, in order to form artificial eyelashes, the precipitation time of the plastic film in the cutting solution may be 5 [hours] or more and 40 [hours] or less.

[0056] After placing the plastic film in the cutting solution on the support rod for precipitation, the cutting solution is precipitated into the cutting solution, and then the height of the cutting solution is adjusted. When adjusting the height, the cutting solution can be naturally discharged, or the position of the support rod in the cutting container can be moved upward to adjust the precipitation time of the plastic film. Therefore, the grinding time difference caused by the cutting solution is used to shorten the grinding time of the base part of the product and extend the grinding time of the tip part, thereby forming a sharp shape. After the grinding process, the product is cleaned to form a final product.

[0057] If the part where the cutting line is formed is precipitated in a strong alkaline cutting solution with a concentration of more than 25[%] and less than 40[%] at a temperature of about 80[℃] for 20[minutes], the cutting line (crack or scratch) formed by the laser beam of the laser cutting machine will first be corroded and cut into the shape of the corresponding cutting line.

[0058] After that, in order to form the tip of the artificial eyelashes sharply, they are further precipitated into the cutting solution. The concentration and temperature of the cutting solution and the precipitation time of the plastic film can be set to a concentration of 25 to 40 [%], a temperature of 80 [°C], and a time of more than 5 [hours] and less than 40 [hours] by taking into account the value that meets the production efficiency and the possibility of developing product defects based on the experimental results of the product oxidation degree.

[0059] The reason for fine processing of the ends of artificial eyelashes is that sharp ends of eyelashes can make consumers look more natural after attachment and the product itself looks better. Therefore, it is necessary to immerse the plastic film with the cutting line in a cutting solution to make the ends sharp.

[0060] Figure 7 This is a reference image comparing the original yarn used for artificial eyelashes and real eyelashes after precipitation in the cutting solution, magnified 250 times. Figure 7 The existing eyelashes have the disadvantage of being uneven in length although the ends are sharp. The artificial eyelashes manufactured according to the present invention have sharp tips and uniform length from the base to the tip.

[0061] The technical concept of the biosorbent production device of the present invention is described above with reference to the accompanying drawings, but it is only an illustrative description of the best embodiment of the present invention and does not limit the present invention.

[0062] Therefore, the present invention is not limited to the above-mentioned specific preferred embodiments, and those skilled in the art can implement various modifications without departing from the gist of the present invention as claimed in the claims, and these modifications all belong to the protection scope recorded in the claims of the present invention.
