Description

False Eyelashes Heat and Manufacturing Method

FIELD OF THE INVENTION [0002] The present invention relates to eye cosmetic products, in particular to false eyelashes fixed to the edge of the eyelid, and more particularly to rows of false eyelashes and methods for their manufacture.

It is a known practice to manufacture rows of false eyelashes by hand gluing the fibers for forming the artificial eyelashes to a base portion for attachment to the eyelid. However, this manual manufacturing method is complex and expensive. In addition, production times can be quite long, limiting productivity.

Also, given the fineness of the fibers intended to form the artificial eyelashes, the artificial eyelashes will remain adhered to the base portion, since the bonding is carried out over a very small, non-planar surface, the artificial eyelashes can be removed from the base portion. There is a risk of falling.

Also known is patent KR 10-1045497, which relates to false eyelashes, which are produced by inserting in a zigzag pattern two threads from which the artificial eyelashes are to be formed, both of which are similarly contracted by a chain stitch. It is fixed to the base yarn by chain stitch, and each base yarn is covered with an insertion yarn.

In this configuration, the manufacturing method is complicated by the fact that the artificial eyelash consists of two yarns inserted in a zigzag pattern and knitted with chain stitches.

There is a need to obtain eyelash arrangements in a simple manner, in which it is impossible to obtain by hand and various curvatures, with more variety than can be obtained by hand.

There is also a need to benefit from manufacturing methods that can reduce production time and increase production regularity. Reducing lead time and purchasing costs can also be useful.

Finally, there is a need to increase the quality level of rows of artificial eyelashes repeatedly obtained by automation while minimizing the number of parts of the production machine by simple means.

Knitted artificial eyelashes

The present invention aims to answer all or some of these needs, and according to one of its aspects, an eyelid with (i) a base portion intended to be fixed to the edge of the eyelid, and (ii) artificial eyelashes. As a row of false eyelashes fixed to the edge,

This object is achieved by a false eyelash row, wherein the base part has a first chainstitch knitting warp, and the artificial eyelashes pass through the chain stitch without binding thereto.

A "row of false eyelashes" is understood to be a row of eyelashes formed entirely of non-natural, synthetic eyelashes, in other words artificial eyelashes.

Artificial eyelashes do not form chain stitches. The artificial eyelashes do not form stitches with the first warp.

A row of artificial eyelashes is obtained which is simple in production, fast and inexpensive. In addition, artificial eyelashes can be placed in a variety of ways on the base portion.

In addition, the heat according to the invention has good resistance to use, in particular when handling and when worn.

It is robust and resistant and can be easily handled without the risk of the artificial eyelashes falling off the base part.

In one embodiment, all of the false eyelashes in the row are formed from a single weft thread. Thus, only one weft thread is used to form all artificial eyelashes. In variations, a row may have a plurality of weft yarns, for example two or more weft yarns. Thus, it is possible to obtain rows of eyelashes with a more natural appearance, in which some artificial eyelashes intersect with others.

The base portion may have a first chainstitch knitting warp yarn, and the weft yarn passes through the chainstitch unbound thereto. The weft does not form a chain stitch. The weft does not form a stitch with the first warp yarn. The weft yarns pass back and forth between two base parts, in particular extending parallel and symmetrically with respect to each other. In a variant, it is possible for the two base parts not to be parallel to each other but to form an angle to each other. The angle may have a non-zero value, for example between 0.5° and 70°.

According to this aspect of the invention, there are no two separate weft yarns forming every false eyelash.

The first warp yarn may form a closed chain stitch. In a variant or additionally, the first warp yarn forms an open chain stitch.

The base portion may have a second chainstitch knitting warp, and the false eyelashes pass through the chainstitch without being tied thereto.

The first warp yarn and the second warp yarn may be interlaced. The artificial eyelashes pass through the chain stitch, but are not tied at the first and/or second warp. The weft yarns pass through the chain stitch, but are not tied in the first and/or second warp yarns. The weft does not form a stitch with the first warp yarn.

The second warp yarn may form a closed chain stitch. In one embodiment, the first and second warp yarns each form a closed chain stitch. In a variant, the first warp yarn forms an open chain stitch and the second warp yarn forms a closed chain stitch.

In a variant or in addition, the second warp yarn may form an open chain stitch. In one embodiment, the first and second warp yarns each form an open chain stitch. In one variant, the first warp yarn forms a closed chain stitch and the second warp yarn forms an open chain stitch.

A "chain stitch" is understood as a stitch forming loops arranged one after the other in the manner of links of a chain, in effect forming a loop passing over the top of the previous loop to form a column of stitches.

"Open chain stitch" is understood to mean that the two ends of a loop cover the top of the previous loop with some non-zero spacing around the width of the loop.

"Closed chain stitch" is understood to mean that the two ends of a loop cover the top of the previous loop with substantially zero spacing, and the two ends are substantially adjacent or even touching.

Creation of open and closed stitches results in stitches made in opposite directions. If both sides are simultaneously made around the needle with two threads, an unravelable effect is obtained.

The artificial eyelashes can be distributed regularly over the base part, in particular eg always arranged at the same regular intervals.

In one variation, the spacing may be irregular. It may decrease along the base portion and then increase. The spacing between two successive artificial eyelashes of an eyelash row is for example 0.07 to 2 mm, preferably 0.5 to 1.5 mm, or 0.9 to 1.25 mm, more preferably 0.99 to 1.11 mm, for example about 1 mm.

In one embodiment, the artificial lashes may be arranged in groups of artificial lashes, with a first small spacing between one and the same group of artificial lashes, and a second large spacing between two consecutive groups. A group of artificial lashes may have 2 to 12 artificial lashes, more preferably 3 to 10 artificial lashes, for example about 6 or 8 artificial lashes. The groups of artificial lashes in a row of lashes may have the same number of artificial lashes, or in a variant, the number varies from group to group along the row of lashes. In one embodiment, the row of eyelashes has a series of groups of two artificial eyelashes, or in a variant, alternating groups of two artificial eyelashes and groups of eight artificial eyelashes, for example.

The first and second warp yarns may be, for example, a first synthetic material selected from, but not limited to, polyolefins, PE, PP, PU, PA, PET, PBT, PES, PTFE, or polyolefins, PE, PP, PU, PA , PBT, PES, PTFE, heat-activatable adhesive or heat-activatable resin, TPU silicone, CoPA, CoPES, TPU, TPE, EVA (ethylene-vinyl acetate), polyolefin, polyethylene, polypropylene, PA , PES, can be made from yarn coated with PVC.

The color selected for the first composite material may be similar to or similar to the color of the user's skin, or in variants the composite material may be transparent. The first gradient and the second gradient may represent more than one color. Each of the first warp yarn and the second warp yarn may have one or more strands as described above.

Artificial eyelashes, and especially weft yarns, for example from the following non-limiting list: a second synthetic material selected from polyolefins, PE, PP, PU, PA, PET, PBT, PES, PTFE, or any other thermoplastic fibres; or even made of natural fibres. It also consists of a core of polyolefins, PE, PP, PU, PA, PBT, PES, PTFE, heat-activatable adhesives or heat-activatable resins, TPU silicones, CoPA, CoPES, TPU, TPE, EVA (ethylene-vinyl acetate), polyolefin, polyethylene, polypropylene, PA, PES, PVC.

The color selected for the second synthetic material may be similar to or similar to the color of the user's eyelashes, or in contrast, a color that contrasts sharply with the color of the user's eyelashes, for example red, black, green, blue, this list includes: Not limiting.

It may be possible to have different weft yarns in terms of diameter and color. Artificial eyelashes, and in particular weft yarns, may exhibit more than one color. They may exhibit eg 1 to 5 different diameters.

The first and second warp and/or artificial eyelashes, and in particular the weft, can be washed in a washing bath according to Oekotex and REACH standards, in order to ensure sufficient hygienic conditions.

The base portion may have additional yarns interwoven with the first chainstitch warp yarns, in particular with the first and second chainstitch yarns.

This additional yarn can block knots and stitches. This may also make it possible to further limit the risk of unraveling of the first and/or second warp and weft thread(s). In addition, it can provide a reinforcing effect of the base part to which it belongs, which is advantageous for good retention of false eyelash rows.

Additional yarn may be added in the base portion comprising the first and second chainstitch knitting warp yarns. In one variation, an additional yarn may be added into the base portion comprising a single first chainstitch knitting warp yarn.

These additional yarns may extend in a zigzag fashion at the base portion.

In one embodiment, all of the false eyelashes in the row are formed from a single weft thread. Thus, only one weft thread is used to form all artificial eyelashes. In variations, a row may have a plurality of weft yarns, for example two or more weft yarns. Thus, it is possible to obtain rows of eyelashes with a more natural appearance, in which some artificial eyelashes intersect with others.

The weft yarns are disposed substantially perpendicular to the base portion with a slight inclination. The weft yarn is cut between the two base portions to separate the base portions to form at least one row of false eyelashes, in particular two rows of false eyelashes. Separation can occur in particular in the median plane or, in a variant, in a plane parallel to one of the base parts, close to the latter, for example at the same height as said base part.

Each base portion may have a first chainstitch knitting warp yarn, and the weft yarn passes through the chainstitch untied to it. The weft does not form a chain stitch. The weft does not form a stitch with the first warp yarn.

Each base portion may have a second chainstitch knitting warp yarn, and the weft yarn passes through the chainstitch untied to it.

A “composite needle” is a needle formed of two parts, namely a body and a sliding element. A body can consist of a butt, stem and hook. The sliding element may consist of a butt and a stem. The sliding element can slide within the stem of the body to close and open the hook of the needle. Thus, the body of the needle and the sliding element can move independently and in a synchronized manner.

Composite needles can produce tighter stitches than latch needles. This tightness makes it possible to ensure that the artificial eyelashes are very well fixed to the base part.

Knitting machines may in particular not have latch needles. A latch needle is a needle composed of a butt, stem and beard, and is a latch articulated to the stem. The latch exhibits an oscillating motion along the axis of the stem, opening and closing the whiskers of the needle. The latch needle needs to work with a sinker that serves to form the stitch.

In the present invention, the knitting machine may in particular not have a sinker. Accordingly, the knitting machine according to the present invention does not have a sinker for forming stitches.

The first warp yarn and the second warp yarn may be interlaced.

The knitting step can be implemented with multiple needles. The knitting step may not in particular be implemented with latch needles. The knitting step may not in particular be implemented by a sinker.

In one embodiment, the assembly has two base parts arranged symmetrically and parallel to each other with respect to the median plane.

In one variant embodiment, the assembly may have three base parts arranged parallel to each other and symmetrically about the median plane. The median plane can for example pass through the central base part, and the two other base parts are arranged on either side of the central base part symmetrically and parallel to each other with respect to the median plane.

The first warp yarn may have a plurality of strands. This construction with a plurality of strands makes it possible to increase the tightness of the stitches of the warp yarn, in particular thanks to the greater internal friction of the yarn. The number of strands of the warp yarn may be between 2 and 100 strands, more preferably between 20 and 70 strands, for example about 34 strands per warp yarn. The cross-section of a strand may have a maximum dimension that may be between 4 μm and 0.3 mm, more preferably between 0.05 mm and 0.15 mm, for example about 0.07 mm.

The first warp yarn and the second warp yarn may be interlaced.

Preferably, at least one warp or warp strand is heat soluble. A heat-soluble yarn or strand may be activated after the knitting step to secure the stitches of the base portion. The term “activation” refers to a temperature increase in a row of false eyelashes that enables partial or complete melting of a heat soluble yarn or strand to be achieved without damaging other yarns or strands that are not heat soluble. Melting of the heat fusible yarn or strand causes it to adhere to adjacent yarns or strands, further enhancing the firmness of the false eyelash row.

Thus, only one weft thread is used to form all artificial eyelashes. In a variant, a row may have a plurality of weft yarns, for example two weft yarns. Thus, it is possible to obtain rows of eyelashes with a more natural appearance, in which some artificial eyelashes intersect with others.

The artificial eyelashes can be held without being tied to them in the stitches of the base part. The weft does not form a stitch with the first warp yarn.

The method may also have a step (e) of activating at least the heat-soluble warp or multi-strand warp strands to secure the stitches of the base portion.

Figure 1 shows a row 10 of false eyelashes intended to be fixed to the edge of an eyelid. This row 10 has (i) a base part 12 intended to be fixed to the edge of the eyelid, and (ii) artificial eyelashes 14.

The base portion 12 has a first chainstitch knit warp yarn 16 through which the false eyelashes 14 pass unhindered. Artificial eyelashes do not form chainstitch. The artificial eyelash is bent into a U shape as shown, and the bottom of the U remains knot-free at the first warp 16.

As shown in the conventional schematic diagram of FIG. 2A, all of the false eyelashes 14 in row 10 are formed from a single weft thread T. Thus, only one weft thread is used to form all artificial eyelashes. In a variant, there may be a plurality of weft yarns, especially in the case of yarns having different colors. The base portion 12 has a first chainstitch knitting warp yarn 16 through which the weft yarn T passes through the chainstitch without being tied to it. Weft yarn T passes back and forth between two base portions 12 extending parallel and symmetrically to each other.

Figure 2a shows an assembly 20 for forming a row of false eyelashes to be secured to the edge of an eyelid, in particular as described above. The assembly 20 has two base parts 12, at least one of which is intended to be fixed to the edge of the eyelid, which are arranged parallel to each other and symmetrically with respect to the median plane P.

Assembly 20 also has artificial eyelashes 14 formed from a single weft thread T that passes back and forth between the two base portions 12 .

The weft yarns are disposed substantially perpendicular to the base portion. The weft is intended to be cut between the two base parts, in particular at the median plane P, to separate the base parts 12 and thus form two rows of false eyelashes. The artificial eyelashes can be distributed regularly over the base part, in particular eg always arranged at the same regular intervals. The weft yarn can be cut close to one of the two base parts without being cut between the two base parts in the median plane (P). In this case, only one row of false eyelashes can be obtained.

In one embodiment shown in FIG. 2b , the assembly has three base parts 12 arranged parallel to each other and symmetrically about the median plane P. The median plane can for example pass through the central base part, and the two other base parts are arranged on either side of the central base part symmetrically and parallel to each other with respect to the median plane. In this case, there are two weft yarns T, and a single weft yarn passes back and forth between the two base parts.

In this variant embodiment, the three base parts are parallel to one of the base parts and close to the latter, eg parallel to one of the base parts and in a first separation plane (P′) flush with said base part. is separated at a second separation plane (P″) close to, for example flush with the base part. In the example shown, the base part in question is the central base part.

In the assembly 20 of FIG. 2A, each base portion 12 has a first chainstitch knit warp 16 through which the weft yarn T passes through the chainstitch without being tied to it. The weft does not form a chain stitch. The weft does not form a stitch with the first warp yarn.

The first warp yarn 16 of the base portion 12 forms a closed chain stitch in the example shown. In a variant or additionally, the first warp yarn forms an open chain stitch.

In the embodiment just described, the row has only one first slope 16 .

In one variation, and as shown in the embodiments of FIGS. 3A-5B , the base portion 12 can have a second chainstitch warp yarn 18 . The artificial eyelashes 14 pass through the chain stitch of this second warp yarn 18 without being tied thereto. In the assembly 20 of FIGS. 3A-5B , each base portion has a second chainstitch knitting warp 18 , the weft yarn passing through the chainstitch without being tied to it. The first warp yarn 16 and the second warp yarn 18 may be interwoven.

The second warp yarn may form a closed or open chain stitch.

In the embodiment shown in Figs. 3a and 3b, the first warp yarn and the second warp yarn each form a closed chain stitch. Closed chain stitches are arranged symmetrically with respect to each other.

In the embodiment shown in Figures 3c and 3d, the first and second warp yarns each form closed chain stitches, which both overlap, meaning that they each follow exactly the same path. Also, the first and second warp yarns each form a closed chain stitch.

In one variant, as shown in Figures 4a and 4b, the first warp yarn forms a closed chain stitch and the second warp yarn forms an open chain stitch.

In another variant, and as shown in Figures 5a and 5b, the first and second warp yarns each form an open chain stitch.

In the embodiments just described, a row has only one weft yarn. It may have two of them, for example as illustrated by way of example in FIGS. 5C and 5D . The second weft yarn (T'), in this example, does not go through all the chain stitches of the warp yarn. Also, the second weft yarn (T') intersects the first weft yarn (T) in places. Accordingly, advantageously, it is possible to form a row of eyelashes having a more natural appearance, such as intersecting some artificial eyelashes with other eyelashes.

The embodiment of FIG. 10 is similar to the embodiment of FIG. 3B, but with the following differences. In the embodiment of FIG. 10 , base portion 12 has an additional yarn 24 interwoven with first chainstitch warp yarns 16 and second chainstitch yarns 18 . In particular, there are two additional yarns 24, one on each base part 12.

Assembly 20 can be obtained by knitting machine 30, as shown in FIG. Knitting machine 30 has multiple needles 32 .

Composite needle 32 is formed of body 33 and sliding element 34 . The body 33 is composed of a butt 33a, a stem 33b and a hook 33c. The sliding element 34 is composed of a butt 34a and a stem 34b. The sliding element can slide inside the stem of the body to close and open the hook 33c of the needle. Thus, the body of the needle and the sliding element move independently and in a synchronized manner.

Knitting machine 30 in particular does not have latch needles with latches articulated to the stem and does not have sinkers.

The knitting machine 30 has a yarn guide 35 on which weft yarns T are deposited to form artificial eyelashes. This yarn guide moves from right to left and from left to right over the composite needle 32 .

The knitting machine 30 also has a first guide bar 36 for supplying the first warp yarn 16 . This first guide bar 36 moves right to left and left to right, and top to bottom and bottom to top to rotate around the compound needle. Left and right movement can vary depending on whether warp yarn 16 is intended to be knit with open or closed chain stitches.

Finally, the knitting machine 30 has a second guide bar 38 for supplying the second warp yarn 18 . This second guide bar 38 moves from right to left and from left to right, and can deposit the second warp into the hook 33c of the compound needle. This second warp yarn 18 makes it possible to better secure the first warp yarn 16, thereby making it difficult to untie the chain stitch of the base part. The nit thus obtained can be unwound.

Now, the manufacturing method of the false eyelash string is explained.

In a first step, between two base parts 12, at least one of which is intended to be fixed to the edge of the eyelid, arranged parallel to each other and symmetrically with respect to the median plane P, and between the two base parts An assembly 20 having artificial eyelashes 14 formed from a single weft yarn T extending back and forth is knitted by multiple needles.

Knitting is such that each base portion has a first chain-stitch knitting warp yarn 16 and a second chain-stitch knitting warp yarn 18, and the weft yarns pass through the chain stitches without being tied to them, and the weft yarns do not form chain stitches. is carried out
