Description

The invention relates to methods for performing cosmetic procedures, namely to methods for performing manicures or pedicures [A45D 29/00].

Known from the prior art is a METHOD FOR MANUFACTURING UV-CURABLE NAIL STICKER AND UV-CURABLE NAIL STICKER [KR102342682B1], which includes an embossed nail sticker having different colors and three ed forms, and cured by ultraviolet rays. The method according to the present invention includes the following steps: forming a UV-curable adhesive layer by applying a UV-curable adhesive to the top surface of the release paper and then drying it; and forming an embossing layer having a three-dimensional shape corresponding to a pattern formed in the hot-stamping mold on an upper surface of the ultraviolet ray-curable adhesive layer. In this embodiment, the thickness of the embossing layer may vary depending on the thickness of the embossing, and preferably the thickness of the layers may be from 0.8 to 0.9 mm, and the protective sheet may have a thickness from 0.1 to 0.5 mm.

The closest in technical essence is an ARTIFICIAL NAIL AND LASER DEVICE FOR GIVING SHAPE TO AN ARTIFICIAL NAIL [KR20190117079A], made of synthetic resin with appropriate elasticity, having various shapes and sizes and a three-dimensional pattern applied on top of it with a laser. The artificial nail is glued on top of a person's nail using glue.

The main technical disadvantages of the analogue and prototype are the insufficient quality of transferring the volumetric ornament onto the human nail, due to the insufficiently optimally constructed process of transferring the volumetric ornament and its subsequent fixation on the human nail.

The technical result of the invention is to improve the quality of transfer of a three-dimensional ornament to a human nail.

The specified technical result is achieved due to the fact that the method of applying a three-dimensional ornament to a human nail is characterized by the fact that initially a form is taken made of transparent silicone with a three-dimensional image in the form of an ornament applied to it, then pigment is applied over the form, then the form is pressed to the surface of the nail and placed under a lamp with a power of 15 to 35 watts for 1.5-2.5 minutes, until the pigment applied on top of the mold polymerizes.

In particular, take a form with a thickness of no more than 0.5 millimeters.

In particular, they take a form made of transparent silicone with a three-dimensional image applied to it using a laser.

In particular, the form is pressed against the front surface of the nail.

In particular, the form is pressed against the inner surface of the nail.

In particular, the form is pressed against the nail and placed under an LED lamp.

In particular, the form is pressed against the nail and placed under a UV lamp.

Implementation of the invention:

In this application, the term “Polygel” means a material for modeling and strengthening nails, combining the properties of gel and acrylic.

The term “UV lamp” means a device equipped with fluorescent light sources that generate ultraviolet radiation that can polymerize the polymer material applied to the human nail, in particular varnish, paint or gel.

The term “engraved” means a three-dimensional pattern applied during the production of the mold using a laser, distinguished by its heterogeneous surface structure, where the smooth parts differ in height from the convex ones.

The term “LED lamp” means a device consisting of a plastic housing and LEDs built into it. When current is applied, the diodes pass it through themselves and create optical radiation, due to which polymerization of materials applied on top of the mold occurs, in particular paint, varnish or gel.

The method of applying a three-dimensional ornament to a human nail is based on the use of forms with a three-dimensional image previously applied to them using a laser. The mold is made of polymer material, in particular silicone. At the same time, the thickness of the form should not exceed 0.5 millimeters. At the rear end of the form there is a tip designed to allow identification numbers, batch series or other graphic images that are not involved in subsequent transfer to the human nail to be applied over it. A design consisting of a convex part and a flat part is engraved on top of the front surface of the mold. Such a non-uniform surface texture of the mold is achieved through a 5-10 watt ultraviolet laser used in the production of molds. The time for applying the design to the mold is from 30 minutes to 3 hours, depending on the complexity and size of the mold being produced.

Due to the heterogeneity of the pattern applied on top of the form, it becomes possible to transfer a three-dimensional ornament to a person’s nail in a fairly short period of time.

A polymer material is applied on top of the mold - a pigment, in particular varnish, paint or gel. Gel polishes, gel paints, polygels, bases, topcoats, pigments, glitter powder washes and other UV curing materials can be used. Then, by pressing a finger, the form is pressed to the front side of the nail or plastic form with the side where the three-dimensional image is located. The pressure applied to the nail is average. Pressing time is from 1.5 to 2.5 minutes until polymerization of the pigment applied on top of the mold occurs in a UV or LED lamp. After polymerization, the same relief pattern remains on the human nail as on the form. For polymerization, UV and LED lamps with a power of 15 to 35 watts can be used. Before using the lamp, at the consumer’s request, it is possible to first use a 5-watt UV lamp for easy fixation of the pigment. If you use a UV flashlight, you need to hold it directed by the radiation source onto the form with the nail for 15 to 60 seconds, and then continue polymerization under a UV or LED lamp for 1 - 1.5 minutes.

In addition, due to the fact that the thickness of the form does not exceed 0.5 millimeters, it becomes possible to use it as a form for transferring a three-dimensional image to the inner surface of the nail. To do this, a relief image is applied to the front side of the mold used using a laser. Afterwards, a polymeric material, in particular varnish, paint or gel, is applied over the front part of the mold. Then the form is pressed against the inside of the artificial nail form with its front side and polymerized in an ultraviolet or LED lamp. After polymerization, the same relief pattern remains on the inside of a person’s artificial nail as on the form. Thus, it is possible to obtain a smooth nail on the outside and voluminous on the inside. The effect is noticeable when using a clear plastic or acrylic human nail mold.

At the same time, the graphic image applied to the form can be different and is set by the manufacturer.

The stated technical result - improving the quality of transferring a three-dimensional ornament onto a human nail - is achieved due to the fact that the form is made of a polymer material, in particular transparent silicone. The selected manufacturing material allows the form to be flexible enough to completely bend around a person’s nail when transferring the design in the form of a three-dimensional ornament and to use the selected form repeatedly. Transparency ensures the passage of UV or LED rays, which allows the polymer pigment located under the mold to successfully polymerize under a UV or LED lamp. In addition, the transparency of the form ensures clarity of the process of transferring a volumetric ornament, and as a result, the possibility of adjusting the process technology in case of its violation, which also affects the quality of the transfer of a volumetric ornament. Using a mold thickness of more than 0.5 mm does not ensure the achievement of the stated technical result, since it significantly reduces the elasticity of the mold, which, within the framework of the claimed method, does not allow it to be fixed qualitatively and the ornament to be transferred without distortion.

Also, the stated technical result is achieved due to the fact that an ultraviolet laser with a power of 5-10 watts is used in preparing the mold. The time for applying the pattern to the mold varies from 30 minutes to 3 hours depending on the complexity and size of the mold being produced. A pattern application time of less than 30 minutes will entail an insufficient degree of elaboration of the shape’s ornament, and more than 3 hours will lead to its inevitable deformation and, as a result, defects. The specified power and time for applying a volumetric ornament to the surface of the form allows you to achieve maximum accuracy of the pattern during its formation and eliminate defects in the form of too large a difference between the levels of the flat and convex parts of the form, which will subsequently lead to a negative effect when transferring a volumetric ornament from the form to a person’s nail - not enough clear pattern.

Also, the stated technical result is achieved due to the fact that the time of pressing the form onto the front or inner surface of the nail is from 1.5 to 2.5 minutes.

A period of time holding the form with a nail under a UV or LED lamp for less than 1.5 minutes will result in an insufficient degree of polymerization of the pigment under the form, which, in turn, will lead to the rejection of the final volumetric ornament. If the shape is held with the nail under a UV or LED lamp for more than 2.5 minutes, an overly active polymerization process may occur, followed by the process of “drying out” the pigment and its subsequent shedding from the nail, which also reduces the quality of the final volumetric ornament.

Also, the stated technical result is achieved due to the fact that UV and LED lamps with a power of 15 to 35 watts are used in the polymerization process. The use of lamps with a power of less than 15 or more than 35 watts may result in either an insufficient degree of polymerization of the pigment under the form, or its excessive drying.

As evidence of the achievement of a technical result, below are the results of three experiments on the production and subsequent operation of forms and other components used within the stated method, used in the process of transferring a three-dimensional ornament to a human nail. The following were investigated in the experiments:

1) Table 1 - results of studying the quality of produced forms using different types of lasers. As part of the experiment, three test samples were studied - P1, P2 and P3. The samples were made of transparent silicone and had the same width of 0.5 millimeters (error 0.012 millimeters). During the experiment, the influence of lasers of various powers on the quality of the final result was studied - the readability of a three-dimensional pattern on the front surface of the form. Objects were mechanically exposed to different lasers three times, after which an average result was obtained for the final percentage of production quality. This indicator was calculated as follows - after obtaining the result for one of the samples, it was compared with the reference template obtained during earlier experiments and which, using the method, showed the best result in the quality of transferring a three-dimensional ornament to a human nail. If there were differences between the test sample and the reference template, the difference was recorded and converted into a percentage for ease of calculation.

Table 1

Prototype being tested Laser power Final percentage of production quality P1 1-5 watts 27.12% P2 5-10 watts 97.2% P3 10-15 watt 7.93%

Based on the results of a study of the effects of UV lasers of various powers, it was experimentally established that it is UV lasers with powers from 5 to 10 watts that produce the most accurate pattern on the surface of a silicone mold. A value below 5 watts entails insufficient elaboration and detail of the pattern, and a power of more than 10 watts results in deformation of the shape. Both outcomes entail negative consequences for the final result of transferring a three-dimensional ornament to a person’s nail due to the defective silicone mold.

2) Table 2 - the results of the experiment on the use of forms made of different materials and widths different from each other. Three experiments were carried out with each of the samples under the same conditions, after which the average value of the desired indicator was displayed - the percentage of readability of the transferred volumetric ornament and the final speed of transfer of the volumetric ornament. The percentage of readability of the final volumetric ornament transferred from the form was calculated by superimposing the final volumetric ornament on a reference template with a readability percentage of 100% and measuring their differences. The speed of transfer of a three-dimensional ornament was measured using one working stopwatch, used in all experiments.

As part of the experiment, the following samples were taken:

1. A patented device with a tip made of transparent silicone 0.5 mm thick (hereinafter referred to as Form 1);

2. A form with a tip, made of opaque silicone 0.5 mm thick (hereinafter referred to as Form 2);

3. A mold with a tip made of transparent silicone 0.6 mm thick (hereinafter referred to as Form 3);

4. A mold with a tip made of transparent silicone 0.4 mm thick (hereinafter referred to as Form 4);

5. A form without a tip, made of transparent silicone 0.5 mm thick (hereinafter referred to as Form 5).

Based on the results of the study, we can draw the following conclusion:

Thanks to the selected material and the presence of the tip, form 1 showed the best result in terms of % readability of the pattern and the final speed of ornament transfer. Due to the presence of the tip, it was possible to immediately establish the optimal “drying” time for the volumetric ornament in a UV and LED lamp for the chosen shape, and due to the fact that the selected silicone was transparent and transmitted LED and UV radiation, it was possible to achieve the maximum readability of the volumetric ornament .

3) Table 3 - results of experiments using various UV and LED lamps and polymer materials. As part of the experiment, the influence of UV and LED lamps of various powers on the final quality of the resulting three-dimensional ornament on a human nail was studied. When using an LED lamp, the ornament polymerized from 1.5 to 2 minutes, and when using a UV lamp from 2 to 2.5 minutes. This is due to the fact that LED lamps differ from UV lamps in their higher radiation intensity, which as a result leads to faster polymerization of the ornament on the nail. For this reason, the experimental results for both types of UV lamps are separated. Three prototypes of transparent forms with a width of 0.5 millimeters were studied with a polymer material applied on top of them, in particular a gel polish made with the possibility of UV and LED curing. After three experiments, the results were averaged and compared with the reference template. The differences between the tested prototype and the template (if any) were recorded and then converted into a percentage.

Table 3

Prototype being tested UV or LED lamp power The final percentage of UV lamp polymerization quality The final percentage of LED lamp polymerization quality P1 1-15 watt 12.91% 23.12% P2 15-35 watt 98.87% 97.63% P3 35-60 watt 11.69% 7.46%

Based on the results of the experiment, we can conclude that when using a UV or LEd lamp with a power of less than 15 watts, the power of the given lamp was not enough for a sufficient level of polymerization of the pigment applied on top of the mold, which resulted in a rather low percentage of the quality of production of the final volumetric ornament. When using a UV or LED lamp with a power of more than 35 watts, the final volumetric ornament dried out too much and began to deform in every possible way - crack and crumble, which also negatively affected the final percentage of the quality of volumetric ornament production. However, when using a UV or LED lamp with a power of 15 to 35 watts, the given power was enough to sufficiently polymerize the form, but prevent the onset of any deformation of the pigment.
