1 is a front view showing a whole work process according to an embodiment of the present invention, Figure 2 is a plan view showing the entire work process according to an embodiment of the present invention, respectively, with reference to the accompanying drawings The manufacturing process of the invention will be described.

In the method for manufacturing hair extension according to the present invention, the hair extension is manufactured by a series of sequential manufacturing steps as follows.

(1) First step: first sewing

As shown in Figs. 1 and 2, a plurality of hair strands for preparing hair extensions are prepared to have a hair bundle 3 arranged laterally in length. At this time, the hair bundle 3 may be human hair or human hair that is the human head.

The hair can be any similar to human hair, but preferably polybutylene terephthalate, which is a synthetic resin with improved texture and feel to be similar to human hair, and antimony oxide to improve flame retardancy as a kind of catalyst.

The prepared hair bundle 3 is put into the first sewing machine 1 to perform the primary sewing 11 in approximately half points or one end of the hair bundle 3. Since the hair bundle 3 is folded around the primary sewing 11 in the process, the primary sewing 11 is preferably made in the transverse direction of the hair bundle 3. Hair bundle 3 is in a state connected by the primary sewing (11).

The primary sewing 11 formed on the hair bundle 3 by the first sewing machine 1 not only becomes a boundary when the hair bundle 3 is folded, but also binds the hair bundle 3 so that the hair strands easily fall out. It does not play a role.

The first sewing machine (1) is a general sewing machine to sew one end of the hair bundle (3) horizontally with the upper thread and the lower thread horizontally so that the hair strands do not easily fall out.

(2) Second step: Bunch of hair  Collapse

The hair bundle 3 having the first sewing 11 completed at one end is introduced into the heat treatment apparatus 4, and the hair bundle 3 is folded around the first sewing 11.

Specifically, the heat treatment apparatus 4 is a device for applying heat to the hair bundle 3 portion of the primary sewing 11 so that the hair bundle 3 is folded around the primary sewing 11. The heat treatment apparatus 4 is installed toward the front of the first sewing machine 1 at intervals from the first sewing machine 1 to line up with the first sewing machine 1.

The heat treatment apparatus 4 has a circular shape and a heater 42 is installed therein so as to transfer heat to the hair bundle 3 portion of the primary sewing 11, and the hair of the primary sewing 11 along the outer circumference. A guide groove 41 through which the bundle 3 portion passes is provided. The cross section of the guide groove 41 is preferably formed in a shape such as “V” which becomes narrower from the outer side to the inner side so that the hair bundle 3 portion of the primary sewing 11 can be easily inserted.

And the semi-circle portion of the lower heat treatment device (4) is installed to be located below the work table (5) on which the first and second sewing machines (1, 2) are installed so that the hair bundle (3) portion of the primary sewing (11) is covered. do.

Accordingly, the hair bundle 3 having the first sewing 11 while passing through the first sewing machine 1 has a portion of the hair bundle 3 of the first sewing 11 formed in the guide groove of the lower half of the heat treatment apparatus 4. 41) while moving along the circumference is naturally folded around the primary sewing 11 by the heat of the heater 42.

The hair bundle 3 part of the primary sewing 11 is folded downward while moving along the circumference of the guide groove 41 of the lower half of the heat treatment apparatus 4 when folded.

”와 같은 반원형태로 형성할 수도 있다.
On the other hand, since the heat treatment apparatus 4 actually uses only the lower half-circle portion when folding the hair bundle 3 around the primary sewing 11, the upper half-circle portion may be unnecessary. Therefore, instead of forming the heat treatment apparatus 4 in a circle, the upper half portion of the circle is cut.

It may also be formed in a semicircular form such as “.

Referring to the process of folding the hair bundle 3 around the primary sewing 11 once again, the primary sewing 11 when the hair bundle 3 consisting of the primary sewing 11 is put into the heat treatment apparatus 4. The portion of the hair bundle 3 is naturally moved along the circumference of the lower half of the guide groove 41 of the heat treatment device (4). At this time, since the heater 42 installed inside the heat treatment apparatus 4 operates, the hair of the primary sewing 11 moving along the lower circumference of the half of the guide groove 41 in the state of being inserted into the guide groove 41. As heat is transferred to the bundle 3 site, the hair bundle 3 is accurately folded around the first sewing 11.

When the hair bundle 3 is folded, the length of the hair bundle 3 is reduced to about half of the initial length of the hair bundle 3, but the amount of the hair bundle 3 is doubled.

(3) Step 3: Second sewing

While passing through the heat treatment apparatus 4, the secondary sewing 12 is made on the hair bundle 3 in a folded state about the primary sewing 11.

Specifically, the second bundle 12 is made in the course of passing through the second sewing machine 2 arranged in a row in front of the heat treatment apparatus 4 in the folded state of the hair bundle 3. The secondary sewing 12 is made at the upper end of the hair bundle 3 folded downward at intervals with the primary sewing 11.

The second sewing machine 2 binds the hair bundle 3 with the upper thread and the lower thread as a general sewing machine. Hair bundle (3) is the first, second sewing machine (1, 2) by the first and second sewing (11, 12) is made firmly bound so that the hair strands do not fall easily.

Meanwhile, a pressure roller 6 and a guide roller 7 may be installed at one end of the work table 5 or the work table 5 between the first sewing machine 1 and the second sewing machine 2. Pressing roller 6 serves to press the hair bundle (3) for the stable movement of the hair bundle (3), the guide roller (7) has a groove formed on the outer periphery of the primary sewing ( 11) Stable transfer can be achieved while the outer groove is covered.

Therefore, the hair bundle 3 can be stably moved from the first sewing machine 1 to the second sewing machine 2 in the sewing process due to the installation of the pressure roller 6 and the guide roller 7.

Here, connecting the upper part of the hair bundle 3 by the first and second sewing 11 and 12 is called a weft. The weft-formed hair bundle 3 is put into a “wig manufacturing apparatus” disclosed in Korean Patent Registration No. 1258270 to attach an adhesive film to one or both front and rear sides of the weft in a heat-sealed manner.

When the adhesive film is attached to the weft, the fixation of the hair bundle 3 is more firmly prevented from falling out of the hair strand of the hair bundle 3, and the portions of the first and second rods 11 and 12 are Since it is wrapped by the adhesive film, the surface is smooth and there is an excellent fit. As a material of the adhesive film, it is preferable to use a polyurethane film. An adhesive may be applied to the weft before attaching the adhesive film to the weft.

The "wig sealing apparatus" disclosed in Patent Registration No. 1258270 includes a work table; A heater provided at one side of the table; Upper and lower film supply parts supplying upper and lower bonding films to cover up and down the temporary coupling parts of the hairs temporarily collected in contact with the heater; And a conveying means for supplying the hair-bonded laminate to which the upper and lower bonding films and the preliminarily combined film are supplied to the heater to fuse the upper and lower laminating films. It is characterized in that it is further provided with a blowing means to avoid tangling.

As described above, the conventional hair extension manufacturing method does not fold the hair bundles by using the wind, so the hair bundle is not folded correctly, and the high occurrence rate of defects is increased. There was a technical problem. However, in the present invention, one end of the horizontally arranged hair bundle 3 is first sewn (11) and then the first part of the hair bundle (3) which is sewn (11) of the heat treatment apparatus 4 formed on the outer periphery of the circle Fold the hair bundle (3) around the first sewing (11) with the guide groove (41) in a row, and the second sewing (12) below the first sewing (11) at intervals from the first sewing (11). It is possible to produce high quality hair extensions with excellent wearing comfort by processing the sewing part to the minimum thickness through minimal sewing.

In addition, the present invention is because only the secondary sewing is made, the processing process can be reduced to significantly increase the production of hair extension, heat treatment apparatus formed on the outer periphery of the hair bundle (3) portion of the primary sewing (11) (4) Pass the guide groove 41 of the) and at the same time by applying heat can be folded the hair bundle (3) around the primary sewing (11) accurately.
