Description

Technical Field

[0001] This utility model relates to the field of wig technology, specifically to an invisible hair extension. Background Technology

[0002] Feather hair extensions are currently very popular in the market. However, due to manufacturing issues, the products retain a certain length of hair retraction during production. This not only increases the product cost (requiring longer hair to create the hair bundles to achieve the required length), but also causes the hair on top to become frizzy after wearing the product for a period of time, affecting both aesthetics and comfort. Furthermore, this process requires manually tying each strand of hair to the connecting line, which is time-consuming, labor-intensive, and too costly.

[0003] Another popular type of cold-applied hair extension (i.e., hair extensions worn with hair loops) involves connecting wires, elastic cords, or wires. Molten glue is applied to the top of the extension head, and the connecting wire, elastic cord, or wire is placed inside. The wire, elastic cord, or wire is then wrapped around the glue and hair by hand. This type of product doesn't require heated pliers to melt the hair extension, making it safer and faster to wear, and is popular with consumers. However, because the connecting wire, elastic cord, or wire needs to be wrapped, if too little glue is applied, it's difficult to secure them, and they are prone to falling off. Insufficient glue also makes it easier for hair to detach from the extension head, reducing the lifespan of the extension. Furthermore, since the extension head is wrapped in glue, the glue mark is quite noticeable, resulting in poor concealment when worn.

[0004] To address the issues with the aforementioned hair extension products, it is necessary to further develop hair extensions that offer better concealment when worn. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an invisible hair extension bundle. Under the same hair volume, the glue head of the hair extension bundle is smaller and thinner than that of other hair extension bundles. This is because it is composed of multiple hair pieces that are staggered vertically, making the glue head of each hair piece smaller. Moreover, the glue head of the lower hair piece is covered by the fake hair strands of the upper hair piece, resulting in better invisibility.

[0006] The technical solution of this utility model is as follows:

[0007] The invisible hair extension includes a connecting line. The lower part of the connecting line is wrapped with at least two hair pieces. The hair pieces are a bundle of fake hair strands fixed together. The hair pieces are fixed to the lower part of the connecting line by elastic cords that are staggered and wrapped around them. The top of the connecting line extends beyond the uppermost hair piece.

[0008] Preferably, the top of the front and back sides of the wig is coated with PU adhesive.

[0009] Preferably, the front side of the wig strands is coated with matte adhesive corresponding to the PU adhesive. When the elastic cord is wrapped, the matte adhesive has a greater frictional force with the elastic cord than the glossy PU adhesive, making the elastic cord less likely to fall off after being wrapped. Also, uneven wrapping may occur when wrapping the elastic cord. If the glossier PU adhesive is exposed, it is easy to see through the hair gaps, making it less invisible than the matte adhesive.

[0010] Preferably, the top of each hairpiece is secured to the lower part of the connecting line by an elastic cord, and the elastic cord covers the top of the hairpiece.

[0011] Preferably, the connecting line is wrapped with 2-3 hairpieces.

[0012] Preferably, the width of the hairpiece is 2-4 mm.

[0013] Preferably, the connecting wire is made of polyester, nylon, TPU or iron wire.

[0014] Preferably, the elastic cord is made of spandex.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] 1. The invisible hair extension of this invention has a smaller and thinner adhesive tip than other types of hair extensions with the same amount of hair. This is because the hair extension of this invention is composed of multiple staggered hair pieces, making the adhesive tip of each hair piece smaller. Furthermore, the adhesive tip of the lower hair piece is covered by the artificial hair strands of the upper hair piece, making it less noticeable. In addition, the invisible hair extension of this invention uses elastic cord for wrapping instead of adhesive fixation, so what is exposed is the thread, which has a texture and resembles real human hair, thus making it even more invisible when worn.

[0017] 2. The invisible hair extensions of this invention are suitable for wearing on the front of the head or other areas with sparse hair, making them more invisible and comfortable; and the hair extensions of this invention can be stacked to meet different hair volume requirements.

[0021] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model.

[0022] Example 1

[0023] like Figure 1 As shown, this embodiment provides an invisible hair extension bundle, including a connecting line 1 made of polyester, nylon, TPU, or wire, preferably polyester or nylon. The function of the connecting line 1 is to subsequently connect the entire hair extension bundle product to the hair extension ring. The lower part of the connecting line 1 is wrapped with two hairpieces 2. The top of each hairpiece 2 is fixed to the lower part of the connecting line 1 by an elastic cord 3 made of spandex, and the tops of the two hairpieces 2 are staggered vertically. The elastic cord 3 covers the top of the hairpiece 2, and the top of the connecting line 1 extends beyond the uppermost hairpiece 2. Wherein, as... Figure 2 As shown, the hairpiece 2 is a bundle of hair strands 201 fixed together, and the front (i.e. the exposed side) and the top of the back of the hair strands 201 are coated with PU glue 4, and the front corresponding to the PU glue 4 is also coated with matte glue 5.

[0024] The process of creating the invisible hair extensions in this embodiment is as follows:

[0025] (1) Preparation: Match the hair root color of the elastic cord 3 and the connecting line 1, and immerse the connecting line 1 in the matte finish. Take it out and let it dry for later use. This will make the connecting line 1 stiffer and easier to pass through the hair extension ring during use. It will also prevent the connecting line 1 from unraveling and make it more durable.

[0026] (2) Fixing the hair strands 201: According to the hair bundle specifications, a bundle of hair strands 201 is sewed together, that is, two rows of lines are sewn near the top of the hair strands 201 to temporarily fix the hair strands 201 together, which is convenient for subsequent glue application.

[0027] (3) Applying adhesive: Fix the hair strands 201 to the glass plate, apply PU adhesive 4 above the thread on this side, let it dry until it is no longer sticky, then apply matte adhesive 5 on the PU adhesive 4. This side is the front of the hairpiece 2. After drying for 2 hours, turn it over and apply PU adhesive 4 above the thread again. Dry it. This side is the back of the hairpiece 2. Then remove the thread from the hair strands.

[0028] (4) Make hairpiece 2: Cut the bundle of fake hair 201 into 3mm wide hairpiece 2 for later use.

[0029] (5) Hair Bundle Making: Place the elastic cord 3 and connecting line 1 into the hair bundle making equipment (using the feather hair extension special ring winding machine disclosed in Chinese Utility Model Patent CN221165482U), paying attention to controlling the tightness of the connecting line 1. Take a hair piece 2, apply PU glue 4 to the back of the hair piece 2, and use the PU glue 4 to firmly attach the top of the hair piece 2 to the connecting line 1 to increase the firmness between the hair piece 2 and the connecting line 1. Use the equipment to wrap the elastic cord 3 around the top of the hair piece 2 and cover the top of the hair piece 2, thus completing the wrapping and fixing of one hair piece 2 on the connecting line 1. Then repeat the above operation to wrap and fix another hair piece 2 above the top of the hair piece 2. Finally, cut the elastic cord 3 and the connecting line 1, thus completing the staggered wrapping and fixing of the two hair pieces 2 on the connecting line 1.

[0030] (6) Hair tie adhesive: Place a pad above the elastic cord near the connecting line 1, and immerse the part above the pad of the connecting line 1 into the matte adhesive again. The pad can prevent the matte adhesive from sticking to the elastic cord. After taking it out, remove the pad and bake at 50°C for more than 4 hours to complete the production.

[0031] The invisible hair extensions produced in this embodiment have smaller and thinner adhesive tips than other types of hair extensions with the same amount of hair. This is because the hair extensions in this embodiment are composed of multiple hair pieces 2 staggered vertically, making the adhesive tips of each hair piece 2 smaller. Furthermore, the adhesive tips of the lower hair piece 2 are covered by the fake hair strands 201 of the upper hair piece 2 and are not easily seen.
