[0035] Figure 1 A flow chart of a method for manufacturing a hair curtain is provided according to an embodiment. DETAILED DESCRIPTION

[0036] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In the description of the present invention, it should be noted that, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, if the terms "first", "second", "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0038] like Figure 1 As shown, the hair curtain manufacturing method provided by the present invention comprises the following steps:

[0039] Step S1, hair strands are batched according to target weight to obtain hair strands. In this embodiment, hair strands weighing 100g are taken as an example for production.

[0040] Step S2, using a double-needle sewing machine to run a first quilting line and a second quilting line on the top of the hair handle to obtain a hair curtain. Specifically, the first quilting line is a pure cotton sewing thread, and the second quilting line is a water-soluble sewing thread. The needle length of the double-needle sewing machine is 30-35 needles / inch, and the distance between the first quilting line and the second quilting line is 3 mm-4 mm. In this way, the hair curtain can be fixed for subsequent production.

[0041] Step S3, using a single-needle sewing machine to run a third quilting line between the first quilting line and the second quilting line of the hair curtain. Specifically, the third quilting line is a pure cotton sewing line, and the distance between the third quilting line and the first quilting line is 1 mm. Since there are two pure cotton sewing lines, the first quilting line and the third quilting line, and the distance between them is only 1 mm, the hair curtain will not have problems such as discomfort caused by the curtain edge being too thick and hard, poor air permeability, etc.

[0042] Step S4, sticking tape along the third quilting line so that the tape covers the hair. Specifically, sticking masking tape along the third quilting line of cotton so that the masking tape covers the hair can prevent the glue from penetrating into the hair during the glue application step and can also shape the hair weft.

[0043] Step S5, applying glue between the first quilting line and the third quilting line, and then drying the hair curtain.

[0044] Step S6, cutting the hair along the first quilting line. Specifically, the protruding excess hair is cut off along the first quilting line of the pure cotton, and only 1 mm of hair above the third quilting line is retained, so that the curtain edge cannot be seen when the hair curtain is worn, and the hair curtain is stable and will not be affected by the sewing line.

[0045] Step S7, remove the masking tape and soak the hair weft in a softener. Since the second sewing thread is a water-soluble sewing thread, the second sewing thread will dissolve and disappear when the hair weft is soaked.

[0046] Step S8, putting the hair weft into a centrifuge for dehydration and drying, and then combing the hair.

[0047] In step S5, the glue is formed by mixing polycarbonate glue, adhesive and diluent. Preferably, step S5 includes the following steps:

[0048] Step S51, applying glue for the first time between the first stitching line and the third stitching line on the front side of the hair curtain and then drying the hair curtain at a temperature of 45° C. to 50° C. for 15 minutes;

[0049] Step S52, applying glue for the second time between the first quilting line and the third quilting line on the front side of the hair curtain and then drying the hair curtain at a temperature of 45° C. to 50° C. for 15 minutes;

[0050] Step S53, applying glue for the third time between the first quilting line and the third quilting line on the front side of the hair curtain and then drying the hair curtain at a temperature of 45° C. to 50° C. for 120 minutes;

[0051] Step S54, applying glue for the fourth time between the first stitching line and the third stitching line on the back of the hair curtain and then drying the hair curtain at a temperature of 45° C. to 50° C. for 15 minutes;

[0052] Step S55, applying the fifth glue between the first stitching line and the third stitching line on the back of the hair curtain and then drying the hair curtain at a temperature of 45° C. to 50° C. for 15 minutes;

[0053] Step S56, after applying the sixth glue between the first quilting line and the third quilting line on the back of the hair curtain, the hair curtain is dried at a temperature of 45° C.-50° C. for 240 minutes.

[0054] Use a scraper to scrape repeatedly each time you apply glue to ensure that the glue is in even contact with the hair, thus fixing the hair.

[0055] Preferably, step S7 comprises the following steps:

[0056] Step S71, adding 2g-3g of sodium hypochlorite solution to 1kg of clean water at 40°C to obtain a first solution, and soaking the hair weft in the first solution for 5 minutes;

[0057] Step S72, washing the hair weft with 40° C. clean water;

[0058] Step S73, adding 30g of softener to 1kg of clean water at 50°C to obtain a second solution, and soaking the hair weft in the second solution for 10 minutes;

[0059] Step S74, adding 40g of softener to 1kg of clean water at 50°C to obtain a third solution, and soaking the hair weft in the third solution for 10 minutes.

[0060] Preferably, step S8 further comprises placing the hair weft in the third solution to slightly wet it, spreading it out flat, scraping off the water, and drying it. Specifically, combing the hair weft after spinning with a fine-tooth comb, scraping off the loose hair on the hair weft, placing it in the third solution to slightly wet it, spreading it out flat on the iron plate, scraping off the excess water with a brush, and then placing it in a drying room at 50° C. to dry it.

[0061] It is understandable that the wig may have a variety of different colors, so step S1 may also include dyeing the hair before batching, obtaining dyed hair bundles after batching, and then making dyed hair curtains.

[0062] Furthermore, the hair curtain manufacturing method further includes step S9, ironing and combing the hair curtain, and then folding the hair curtain, bundling and packaging for transportation.

[0063] The present invention provides a method for manufacturing a hair curtain, comprising the following steps: batching hair strands according to a target weight to obtain a hair curtain; using a double-needle sewing machine to run a first quilting line and a second quilting line on the top of the hair curtain to obtain a hair curtain; using a single-needle sewing machine to run a third quilting line between the first quilting line and the second quilting line of the hair curtain; pasting a tape along the third quilting line so that the tape covers the hair strands; applying glue between the first quilting line and the third quilting line, and then drying the hair curtain; cutting the hair strands along the first quilting line; soaking the hair curtain in a softener; placing the hair curtain in a centrifuge for dehydration and drying, and then combing the hair strands. The hair curtain manufactured by the method of the present invention has high production efficiency and short hair without folding back. Compared with the hair curtains woven by hand, the loss is small and hair loss is not easy to fall off. Compared with the hair curtains manufactured by the three-in-one machine, there is no problem of discomfort and poor air permeability caused by the curtain edge being too thick and hard, and it will not irritate the skin.
