Description

Technical Field

[0001] The present invention relates to the technical field of false eyelashes, and particularly to an eyelash graft and a root pressing process thereof. Background Art

[0002] In the production process of existing false eyelashes, the roots of eyelash filaments are fixed together through a wire bonding process. During the wire bonding process, an adhesive is dissolved by a solvent and then applied between a polyester thread and the roots of the false eyelashes. Then, a hair dryer is used to heat the adhesive until it solidifies to form a wire glue stem, which fixes and connects the roots of the false eyelashes together. However, this wire bonding process cannot accurately control the adhesive, and the adhesive will flow to areas outside the roots of the eyelash filaments, resulting in glue overflow during the wire bonding process. Due to the high aesthetic requirements for false eyelashes and the relatively thin wire glue stem, it is difficult to handle the overflowed glue after the glue overflows, resulting in the unusability of the false eyelashes after glue overflow, thereby leading to unstable quality of the false eyelashes. The wire glue stem formed after wire bonding is hard and inelastic. The existing adhesive is a solvent-based glue, which has a certain volatility, is neither environmentally friendly nor safe. Moreover, when using false eyelashes, it is necessary to apply false eyelash glue on the wire glue stem and then paste the wire glue stem under the natural eyelashes, which is inconvenient to wear. Also, due to the elliptical cross-section of the glue wire stem, the contact area between the glue wire stem and the false eyelashes is small, resulting in an insecure wearing situation.

[0003] Therefore, there is a need for an eyelash graft and a root pressing process thereof to solve the above problems. Summary of the Invention

[0004] The present invention provides an eyelash graft and a root pressing process thereof. The roots of the eyelash graft are fixed by a pressing method. Compared with the traditional wire bonding process, the occurrence of glue overflow is avoided, ensuring the stability of the quality of the eyelash graft. Moreover, the glue strip has a multi-layer sheet structure. Compared with the wire glue stem with an elliptical cross-section, the glue strip has a larger area that can be pasted when wearing the eyelash graft, making the eyelash graft more firmly adhered.

[0005] One technical solution of the present invention is implemented as follows:

[0006] The eyelash graft includes a plurality of long strip membranes and multiple layers of eyelash filaments. At least one adhesive surface is provided on each long strip membrane, and the roots of each layer of eyelashes are adhered to one of the adhesive surfaces. All the long strip membranes are fixed together by pressing to form an integrated glue strip.

[0007] As a preferred technical solution, all the long strip membranes are fixed together by pressing at room temperature.

[0008] As a preferred technical solution, all the long strip membranes are fixed together by pressing under heating conditions.

[0009] As a preferred technical solution, the adhesive surface on each of the long strip diaphragms is bonded to the adjacent long strip diaphragm.

[0010] As a preferred technical solution, the temperature during the pressing of the long strip diaphragms is between -10°C and 180°C.

[0011] As a preferred technical solution, the long strip diaphragm can be set to any one of transparent, black or colored.

[0012] As a preferred technical solution, the thickness of the long strip diaphragm is between 0.02 - 0.12 mm.

[0013] As a preferred technical solution, a long strip diaphragm is adhesively bonded to the upper side of the root of the eyelash filaments on the top layer.

[0014] As a preferred technical solution, a peelable protective film covers the upper adhesive surface of the long strip diaphragm on the top layer; and / or a peelable protective film covers the lower adhesive surface of the long strip diaphragm on the bottom layer.

[0015] As a preferred technical solution, after tearing off the protective film, the eyelash graft is applied to the upper or lower side of the individual's natural eyelashes.

[0016] As a preferred technical solution, the eyelash graft includes a plurality of eyelash clusters. The roots of each eyelash cluster are fixed together by pressing at normal temperature. Each eyelash cluster includes a plurality of eyelash filaments, and the roots of adjacent eyelash filaments are staggered.

[0017] As a preferred technical solution, the eyelash graft includes a plurality of eyelash clusters. The roots of each eyelash cluster are fixed together by pressing at normal temperature. Each eyelash cluster includes a plurality of eyelash filaments, and adjacent eyelash filaments are evenly distributed.

[0018] As a preferred technical solution, the rubber strip comprises the following components in parts by weight: 60% - 70% of SBS, 20% - 30% of tackifying resin, and 5% - 15% of plasticizer.

[0019] Another technical solution of the present invention is implemented as follows:

[0020] A root pressing process for an eyelash graft, specifically comprising the following steps:

[0021] S1. Bond a plurality of eyelash filaments together through an adhesive member to obtain a single-layer eyelash filament sheet;

[0022] S2. Repeat the operation step S1 to obtain multiple groups of the single-layer eyelash filament sheets;

[0023] S3. Produce a long strip film with at least one adhesive surface;

[0024] S4. Bond the roots of the first group of single-layer eyelash filaments to the adhesive surface of the first long strip film, stack the second long strip film on the adhesive surface of the roots of the first group of single-layer eyelash filaments, and bond the roots of the second group of single-layer eyelash filaments to the adhesive surface of the second long strip film;

[0025] S5. Repeat operation step S4 to bond the roots of multiple groups of single-layer eyelash filaments together. At the same time, stack multiple long strip films together;

[0026] S6. Press and bond multiple long strip films to form an integrated rubber strip;

[0027] S7. Determine the eyelash filament cutting line, which is located between the adhesive part and the rubber strip and close to the rubber strip, and cut off the waste part of the single-layer eyelash filaments along this eyelash filament cutting line to obtain the eyelash graft with the roots fixed together.

[0028] As a preferred technical solution, in step S6, after multiple long strip films are pressed at room temperature, the adhesive surfaces on the long strip films are bonded to adjacent long strip films to form the integrated rubber strip.

[0029] As a preferred technical solution, in step S5, after multiple long strip films are stacked together, bond a long strip film on the upper side of the roots of the single-layer eyelash filaments at the top.

[0030] As a preferred technical solution, after multiple long strip films are pressed and bonded to form the rubber strip, cover the upper adhesive surface of the top long strip film with a peelable protective film; and / or cover the lower adhesive surface of the bottom long strip film with a peelable protective film.

[0031] Adopting the above technical solutions, the beneficial effects of the present invention are:

[0032] Since the eyelash graft includes multiple long strip membranes and multiple layers of eyelash filaments, and the long strip membranes are provided with adhesive surfaces, the roots of the multiple layers of eyelash filaments can be pressed together with the multiple long strip membranes by means of normal temperature pressing, so that the fixation of the eyelash graft at the root is realized by pressing at normal temperature. Compared with the traditional thread joining process, there is no need for heating, and the processing process is simple. At the same time, the occurrence of glue overflow is avoided, ensuring the stability of the quality of the eyelash graft. After the multiple long strip membranes are pressed together to form a glue strip, the glue strip presents a multi-layer sheet structure. Compared with a wire glue stem with an elliptical cross-section, the glue strip has a larger area that can be pasted when wearing the eyelash graft, making the eyelash graft stick more firmly, and the wearing is soft and without a feeling of touch.

[0033] After the multiple long strip membranes are pressed together to form a glue strip, the adhesive surface on each long strip membrane is bonded to the adjacent long strip membrane, ensuring that the formed glue strip is integrated, thus ensuring the stability when wearing the eyelash graft.

[0034] The transparent long strip membrane makes the formed glue strip transparent after pressing, thus ensuring the invisible feature when wearing the eyelash graft.

[0035] Since the root of the top-layer eyelash filaments in the eyelash graft is bonded with a long strip membrane, and a peelable protective film is covered on the adhesive surface on the upper side of the long strip membrane, this makes the eyelash graft have self-adhesiveness. When wearing the eyelash graft, there is no need to apply false eyelash glue. After tearing off the protective film, the adhesive surface on the upper side of the above-mentioned long strip membrane can be bonded to the lower side of the individual's natural eyelashes.

[0036] Since the lower side of the bottom-layer long strip membrane in the glue strip is provided with an adhesive surface, and a peelable protective film is covered on the adhesive surface, this makes the eyelash graft have self-adhesiveness. When wearing the eyelash graft, there is no need to apply false eyelash glue. After tearing off the protective film, the above-mentioned adhesive surface can be bonded to the upper side of the individual's natural eyelashes.

[0037] In the present invention, through the cooperation of the long strip membrane, the bonding surface and the protective film, not only does the eyelash graft have self-adhesiveness. Compared with the existing false eyelashes pasted on natural eyelashes by applying false eyelash glue, the false eyelash glue is more obvious after wearing the existing false eyelashes, and the invisible effect is poor. While in the present invention, the eyelash fusion object does not need to apply false eyelash glue, and the wearing is simpler, more convenient, softer, without a feeling of touch, and has a good invisible effect.

[0038] The protective film can protect the adhesive surface, improve the weather resistance of the adhesive surface, and thus improve the shelf life of the present invention. Description of the Drawings

[0058] The upper adhesive surface of the strip diaphragm 2 on the top layer is covered with a peelable protective film 6. And / or the lower adhesive surface of the strip diaphragm 2 on the bottom layer is covered with a peelable protective film 6.

[0059] After removing the protective film 6, the lash graft 1 is applied to the upper or lower side of the individual's natural lashes.

[0060] When using the lash graft of the present invention, the protective film 6 may not be removed. At this time, neither the upper side nor the lower side of the adhesive strip 5 has adhesiveness. Apply false lash glue to the adhesive strip 5 and then bond the adhesive strip 5 to the individual's natural lashes.

[0061] The adhesive strip 5 comprises the following components by weight parts: SBS 60%, tackifying resin 30%, plasticizer 10%.

[0079] In step S6, after multiple strip films 2 are pressed together at normal temperature, the adhesive surfaces on the strip films 2 are bonded to adjacent strip films 2 to form an integrated adhesive strip 5.

[0080] In step S5, after multiple strip-shaped membrane pieces 2 are stacked together, a strip-shaped membrane piece 2 is adhered to the upper side of the root 4 of the single-layer eyelash filament piece 9 at the top.
