Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of hair product manufacturing, in particular to a synthetic braided hair and a manufacturing method thereof. BACKGROUND

[0002] Wigs are made of artificial technology, which are used as decorations on human hair. With the development of economy and the improvement of people's aesthetic level, the wig market is now more and more popular. These braided hair products are usually attached to human hair by braiding or splicing with special hair pins. As a very convenient accessory, the ponytail wig can instantly change the hairstyle and improve the temperament of the person, and it is also very convenient to maintain. Therefore, it is particularly favored by women who pursue fashion.

[0003] At present, the materials used for wigs are mainly natural materials such as human hair and animal hair, as well as synthetic fibers. According to the trend of the hair design industry, women's hairstyles have changed in recent years, and the development of synthetic hair products is conducive to providing new and fashionable hairstyles to the beauty and hairdressing market.

[0004] Chinese invention patent (application number: 201811331209.0) discloses a new synthetic braided hair and a manufacturing method thereof. The synthetic braided hair includes: a first synthetic fiber bundle composed of many synthetic fibers and having a natural end shape; a second synthetic fiber bundle composed of many synthetic fibers and having a natural end shape, the length of the synthetic fibers of which is half of the length of the first synthetic fiber bundle. The second synthetic fiber bundle is aligned with the center of the first synthetic fiber bundle and merged, and is bent together to form a hook shape. The manufacturing method includes: stretching the first synthetic fiber bundle; stretching the second synthetic fiber bundle; aligning the second synthetic fiber bundle with the center of the first synthetic fiber bundle, and bending the first synthetic fiber bundle and the second synthetic fiber together along the center to form a hook shape.

[0005] The product provided by the above application makes it easier for the user to attach the hair strands to the hair without the need for the hair stylist to perform additional stretching and trimming work when weaving the hair for the customer. However, the product and its manufacturing process require two or more hair strands of different lengths, and each hair strand of each hair bundle has the same length. Then, each hair bundle needs to be stretched to form a natural hair tip at the tail of each end of the hair bundle, i.e. the hair strands at the tail of the hair bundle gradually become sparse and thin. On this basis, the hair bundles are concentrically combined and folded to obtain the desired synthetic woven hair. This process requires two or more hair bundles to be obtained and processed, which is time-consuming and inefficient. In addition, the outer contour of the combined hair bundle after stretching of the multiple hair bundles of different lengths is a relatively single shape similar to a horse tail, and the outer contour of the mixed hair strands appears uneven in layers, i.e. after the multiple hair bundles are combined, the thickness of the hair strands at some positions is different due to the combination, resulting in uneven layers of the outer contour. Furthermore, the hair strands of the combined hair bundle appear uneven at different positions. For example, the hair tips at the tail of each end of the stretched shorter hair bundle are thin and sparse, and the longer hair bundle has relatively light stretching of the middle hair strands. After they are combined and mixed, the thickness of the hair strands at some positions is uneven, and the outer contour appears uneven, which affects the overall level and smooth and natural beauty of the entire hair bundle. Therefore, the product produced by this process is only suitable for relatively fluffy woven hair.

[0006] If two or more synthetic hair bundles of different lengths and each hair strand of each hair bundle has the same length are combined first and then stretched, the above problems can be better solved, but the gradient of each end of the hair bundle is uneven, resulting in relatively poor weaving level. In addition, if the lengths of different hair bundles differ greatly, and the centers of the combined hair bundles are required to be aligned, the tail of the shorter hair bundle will appear at some position of the longer hair bundle after the center alignment. If the tail of the shorter hair bundle appears at about one-half or closer to the center of the longer hair bundle, it is not easy to hold the position of the end of the hair bundle, which will increase the difficulty of the stretching operation. If the hand does not hold the shorter hair strands well, the center of the hair strands will shift uncontrollably during stretching, i.e. deviate from the center of the entire hair bundle, resulting in an increase in the rejection rate of the stretched product.

[0007] Therefore, when two or more synthetic hair bundles of different lengths and each hair strand of each hair bundle has the same length are used, whether the single hair strand is stretched first and then combined or combined first and then stretched, there are various factors that affect the quality of the product, and there are also disadvantages of time-consuming and labor-intensive.

[0008] Therefore, how to design a synthetic braided hair which is tied and bundled and a manufacturing method thereof to solve the above-mentioned problems and deficiencies of the synthetic braided hair which is composed of a plurality of bundles of synthetic hair with different lengths and each hair bundle has the same length of each hair is an urgent technical problem to be solved at present.

[0018] Further improvement on the above technical solution: the first tying rope and the second tying rope are both elastic rubber bands, and the tied synthetic chemical weaving is fixedly combined with the inner hanging hook of the packaging box through the first tying rope.

[0019] The first tied synthetic chemical weaving manufacturing method of the present application, characterized in that the method comprises the following steps: Step 1: obliquely cutting the two ends of a synthetic hair bundle to form oblique cutting surfaces with an oblique angle to the length direction of the synthetic hair bundle; Step 2: combing the hair to form a predetermined outer edge contour; Step 3: further stretching the middle and end parts of the synthetic hair bundle to shape the end contour with a predetermined natural shape; Step 4: tying the center of the synthetic hair bundle with the first tying rope; Step 5: folding the synthetic hair bundle at the center of the first tying rope to form a tied synthetic chemical weaving.

[0020] Further improvement to the above technical solution: In step 3, the hair strands are stretched by heating and stretching, with emphasis on stretching the ends of the hair strands, so that the bundle of hair reaches the predetermined length and the ends of the hair form the predetermined hair tip shape.

[0021] Further improvements to the above technical solution: After step 5 is completed, proceed to step 6: Use a second tie to further tie the entire hair strand in the folded braided head, so that the head forms a buttonhole.

[0022] The first specific implementation of the above manufacturing method: In step 1, two oblique cut surfaces of a bundle of synthetic hair are symmetrically arranged, with the angles of inclination of the two oblique cut surfaces being α and β, respectively. The angles of α and β are the same, and the angles of inclination of the two oblique cut surfaces are greater than 20° and less than 90°. The shortest hair strand in the bundle of synthetic hair is La, and the longest hair strand is Lb, with 80% ≥ La / Lb ≥ 50%. In step 5, at the tying point of the first tying cord, a bundle of synthetic hair is folded towards the side of the shortest hair strand La to form a tied bundle of synthetic braided hair. Its outer contour is generally waterfall-shaped, and its bottom forms a relatively flat or concave arc shape.

Step 5: Use the second tie to tie the entire hair at the neck of the head where the hair is tied into a braid, forming a buttonhole shape at the head where the hair is tied into a braid, and forming a ponytail shape at the middle and lower part of its outer edge outline.

[0026] Compared with the prior art, the present invention has the following advantages and positive effects: This invention uses only a bundle of synthetic hair, with both ends obliquely cut at an angle to its length. A first tying cord is used to tie the bundle at its center, and the tied area is bent and folded to form a pre-defined outer contour, creating a tied, bundled synthetic braid. This achieves a gradient change in hair length, enhancing the layering and naturalness of the braid, and facilitating processing. Furthermore, a combination of mixed combing and stretching combing techniques makes the outer contour of the braid more natural and three-dimensional. Adjusting the processing technology facilitates the formation of various outer contours for the tied, bundled synthetic braid; the processing technology is reasonable, convenient, and efficient. Moreover, the double tying method with the tying cord ensures the braid maintains a stable shape, facilitating storage, transportation, and use. Attached Figure Description

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0030] A specific embodiment of the present invention for a bundled synthetic hair includes a bundle of synthetic hair, the two ends of which are oblique cuts, and the length direction of the hair strands forms a predetermined angle with the oblique cuts. The bundle of synthetic hair is tied to the center of the bundle of synthetic hair with a first tying rope 3, and the hair bundle is bent and folded at the tying point to form a bundled synthetic hair with a predetermined outer contour.

[0031] To achieve different outer contours, the hair bundles can be folded in different directions at the tying point, as detailed in Example 1 and Example 2 of the composite braided hair bundles below.

[0032] See Figures 1-6Embodiment 1 of the present invention provides a method for tying synthetic hair into bundles: Preferably, a bundle of synthetic hair includes a predetermined 4000-6000 synthetic hair strands. The two ends of the bundle of synthetic hair are cut into two symmetrically arranged oblique surfaces (including a left oblique surface 1.1 and a right oblique surface 1.2), forming a single bundle of synthetic hair 1 with symmetrical oblique surfaces. The included angle of inclination of the left oblique surface 1.1 is α, and the included angle of inclination of the right oblique surface 1.2 is β. The angles α and β are the same, and the included angle of inclination of the two oblique surfaces is greater than 20° and less than 90°. Figure 1 As shown, preferably, the angle between the two oblique cuts is 40°, i.e., α=β=40°. This condition ensures that the extension lines of the oblique cuts intersect on the extension lines of the center point of the hair bundle. In addition, according to the customer's needs, the hair strands can be made to visually form different natural gradients and layers, enhancing the three-dimensionality and dynamic beauty of the braid. The shortest hair strand in a bundle of synthetic hair is La, and the longest hair strand is Lb. 80% ≥ La / Lb ≥ 50%. Preferably, La / Lb=3 / 5. This condition ensures the overall layering of the outer contour formed after the hair bundle is folded in half, so that the braid can show rich detail and layering while maintaining overall layering coordination. The first tie rope 3 is tied to the center of a bundle of synthetic hair. At the tying point of the first tie rope 3, the bundle of synthetic hair is folded towards the side of the shortest hair strand La to form a tied bundle of synthetic braid. Its outer contour is generally waterfall-shaped, and its bottom forms a relatively natural flat shape. Figure 3 ) or concave arc shape ( Figure 5 This bundling structure not only stabilizes the overall shape of the hair bundle but also gives the braid a unique appearance, making it easy for users to style according to their personal preferences. Additionally, after tying the hair bundle with the first three ties or folding the bundle in half, comb the ends of the hair in the middle and bottom of the bundle to create a natural waterfall-like outer edge. Figure 4 and Figure 6 (As shown).

[0033] See Figure 1 , Figure 7 , Figure 8 Embodiment 2 of the present invention provides a method for tying synthetic hair into bundles: Preferably, a bundle of synthetic hair includes a predetermined 4000-6000 synthetic hair strands. The two ends of the bundle of synthetic hair are cut into two symmetrically arranged oblique surfaces (including a left oblique surface 1.1 and a right oblique surface 1.2), forming a single bundle of synthetic hair 1 with symmetrical oblique surfaces. The included angle of inclination of the left oblique surface 1.1 is α, and the included angle of inclination of the right oblique surface 1.2 is β. The angles α and β are the same, and the included angle of inclination of the two oblique surfaces is greater than 20° and less than 90°. Figure 1As shown, preferably, the angle between the two oblique cuts is 40°, i.e., α=β=40°. This condition ensures that the extension lines of the oblique cuts intersect on the extension lines of the center point of the hair bundle. In addition, according to the customer's needs, the hair strands can be made to visually form different natural gradients and layers, enhancing the three-dimensionality and dynamic beauty of the braid. The shortest hair strand in a bundle of synthetic hair is La, and the longest hair strand is Lb. 80% ≥ La / Lb ≥ 50%, preferably, La / Lb=3 / 5. This condition ensures the overall layering of the outer contour formed after the hair bundle is folded in half, so that the braid can show rich detail and layering while maintaining overall layering coordination. The first tie rope 3 is tied to the center of a bundle of synthetic hair. At the tying point of the first tie rope 3, the bundle of synthetic hair is folded towards the side of the longest hair strand Lb to form a tied bundle of synthetic braid. Its outer contour is generally waterfall-shaped, and its bottom is an outward convex arc shape (e.g., Figure 7 As shown), the outer edge contour is teardrop-shaped or heart-shaped. Under a fixed angle of cut, this mainly depends on the ratio between the shortest hair strand L1 and the longest hair strand L2. Additionally, after tying the hair bundle with the first tie or folding the hair bundle in half, comb the ends of the hair in the middle and bottom of the bundle to create a natural waterfall-like outer edge contour and a natural outward-convex arc contour at the bottom of the bundle (as shown). Figure 8 (As shown).

[0034] See Figure 1 , Figure 2 , Figure 11 Embodiment 3 of the present invention provides a method for tying synthetic hair into bundles: Preferably, a bundle of synthetic hair includes a predetermined 4000-6000 synthetic hair strands. The two ends of the bundle of synthetic hair are cut into two symmetrically arranged oblique surfaces (including a left oblique surface 1.1 and a right oblique surface 1.2), forming a single bundle of synthetic hair 1 with symmetrical oblique surfaces. The included angle of inclination of the left oblique surface 1.1 is α, and the included angle of inclination of the right oblique surface 1.2 is β. The angles α and β are the same, and the included angle of inclination of the two oblique surfaces is greater than 20° and less than 90°. Figure 1As shown, preferably, the angle between the two oblique cuts is 40°, i.e., α=β=40°. This condition ensures that the extension lines of the oblique cuts intersect on the extension lines of the center point of the hair bundle. Furthermore, according to the client's needs, different natural gradients and layers can be visually created in the hair strands, enhancing the three-dimensionality and dynamic beauty of the braid. The shortest hair strand in a bundle of synthetic hair is La, and the longest hair strand is Lb, with 80% ≥ La / Lb ≥ 50%. Preferably, La / Lb=3 / 5. This condition ensures the overall layering of the outer contour formed after folding the hair bundle, allowing the braid to maintain overall layered harmony while showcasing rich detail and layering. The hair strands, after being obliquely cut at both ends of a bundle of synthetic hair, are mixed and combed to create a predetermined end contour. The hair strands are further stretched and combed to create a fluffy and natural look (e.g., ...). Figure 2 As shown), the first tying rope 3 is then used to tie the hair in the center of the bundle, and the hair is bent and folded in half at the tying point to form a tied bundle of hair. The overall outer contour is fluffy and natural, and the lower middle part of the outer contour forms a ponytail shape.

[0035] Furthermore, use the second tying cord 4 to tie the entire hair at the neck and head where the braided hair is tied, forming a buttonhole 5 at the head where the braided hair is tied, with the lower middle part of its outer edge forming a ponytail shape (as shown). Figure 11 (As shown). This facilitates the packaging, transportation, and display of the hair product.

[0036] See Figure 9 , Figure 10 , Figure 11 Embodiment 4 of the present invention provides a method for tying synthetic hair into bundles: Preferably, a bundle of synthetic hair includes a predetermined 4000-6000 synthetic hair strands. The two ends of the bundle of synthetic hair are cut into two parallel oblique surfaces (including a left oblique surface 2.1 and a right oblique surface 2.2) to form a single bundle of synthetic hair 2 with parallel oblique surfaces (e.g., Figure 9 As shown), each hair strand is approximately the same length, and their centers are arranged in a sequential, continuous gradient misalignment. This parallel beveled surface simplifies the beveled cutting process, greatly improving work efficiency. The angle of inclination of the left beveled surface 2.1 is α, and the angle of inclination of the right beveled surface 2.1 is β, α≠β, α+β=180°. Preferably, α is 140° and β is 40°. The hair strands are mixed and combed so that the outlines of the two ends of a bundle of synthetic hair are in a predetermined mixed shape. The two ends of the bundle of synthetic hair are stretched and combed so that the two ends are in a natural hair tip shape (such as...). Figure 10As shown), a first tying cord 3 is used to tie the hair bundle at the center. The tying point of the first tying cord 3 is bent and folded in half to form a tied, braided hair bundle with a predetermined outer edge contour, the outer edge of which is a natural outward-convex arc shape. Then, a second tying cord 4 is used to tie the folded hair bundle at the nape of the neck, forming a buttonhole 5, thus forming a tied, braided hair bundle. The top of its outer edge contour is the buttonhole 5, and the bottom is a natural outward-convex arc shape or a ponytail shape (as shown). Figure 11 (As shown).

[0037] In the above-described embodiments 3-4 of the bundled synthetic braided hair, the first tying cord 3 and the second tying cord 4 can be ordinary hair ties, hairbands, etc., but elastic rubber bands are preferred for easy tying and untying. Furthermore, the bundled synthetic braided hair can be secured together with the first tying cord 3 to the inner hooks of the packaging box. This facilitates the packaging, transportation, and display of the braided hair.

[0038] A specific embodiment of the manufacturing method of the first type of synthetic braided hair tied into bundles according to the present invention includes the following steps: Step 1: Cut both ends of a strand of synthetic hair at an angle to its length. Step 2: Comb the hair to blend it and form the desired outer outline; Step 3: Further stretch the middle and ends of a strand of synthetic hair to shape it into a predetermined natural-looking end profile; Step 4: Tie the center of the bundle of hair with the first tie cord; Step 5: Fold the bundle of synthetic hair in half at the center of the first tying rope 3 to form a synthetic chemical braid.

[0039] Specifically: In step 3 above, the hair strands are heated and stretched on the stretching table, especially the ends, so that the bundle of hair reaches the predetermined length and the ends are shaped into the predetermined tip shape. Through precise stretching and combing, the braid is styled to have a predetermined natural outer contour, enhancing the three-dimensionality and realism of the braid.

[0040] See Figures 1-6 Example 1 of the manufacturing method for the first type of synthetic hair bundle of the present invention involves preparing a bundle of synthetic hair, comprising a predetermined 4000-6000 synthetic hair strands, and the manufacturing method includes the following steps: Step 1: Cut the two ends of a bundle of synthetic hair into two symmetrically arranged oblique surfaces (including oblique surface 1.1 on the left end and oblique surface 1.2 on the right end), forming a single bundle of synthetic hair 1 with symmetrical oblique surfaces. The angle of inclination of oblique surface 1.1 on the left end is α, and the angle of inclination of oblique surface 1.2 on the right end is β. The angles of α and β are the same, and the angle of inclination of the two oblique surfaces is greater than 20° and less than 90°. The shortest hair strand in the bundle of synthetic hair is La, and the longest hair strand is Lb. 80% ≥ La / Lb ≥ 50%.

[0041] Step 2: Comb the hair strands to mix them and form a predetermined outer outline; preferably, comb the hair strands on a combing table to mix them. This step aims to distribute the hair strands evenly and lay the foundation for subsequent steps.

[0042] Step 3: Further stretch the middle and ends of a strand of synthetic hair to shape it into a predetermined natural end profile; preferably, further stretch and comb the middle and ends of the tied synthetic braid on a combing board.

[0043] Step 4: Tie the center of the hair bundle with the first tie cord 3; preferably, the first tie cord 3 is an elastic rubber band. When tying with a rubber band, the tightness can be adjusted to ensure the stability of the hair bundle, while avoiding excessive tightness that could deform the hair.

[0044] Step 5: At the tying point of the first tying rope 3, fold a bunch of synthetic hair towards the shortest hair strand La to form a tied synthetic braid. The overall outline of the braid is waterfall-shaped, and the bottom is relatively flat or concave arc-shaped.

[0045] See Figure 1 , Figure 7 , Figure 8 Example 2 of the manufacturing method for the first type of synthetic hair bundle of the present invention involves preparing a bundle of synthetic hair, comprising a predetermined 4000-6000 synthetic hair strands, and the manufacturing method includes the following steps: Step 1: Cut the two ends of a bundle of synthetic hair into two symmetrically arranged oblique surfaces (including oblique surface 1.1 on the left end and oblique surface 1.2 on the right end), forming a single bundle of synthetic hair 1 with symmetrical oblique surfaces. The angle of inclination of oblique surface 1.1 on the left end is α, and the angle of inclination of oblique surface 1.2 on the right end is β. The angles of α and β are the same, and the angle of inclination of the two oblique surfaces is greater than 20° and less than 90°. The shortest hair strand in the bundle of synthetic hair is La, and the longest hair strand is Lb. 80% ≥ La / Lb ≥ 50%.

[0046] Step 2: Comb the hair strands to mix them and form a predetermined outer outline; preferably, comb the hair strands on a combing table to mix them. This step aims to distribute the hair strands evenly and lay the foundation for subsequent steps.

[0047] Step 3: Further stretch the middle and ends of a strand of synthetic hair to shape it into a predetermined natural end profile; preferably, further stretch and comb the middle and ends of the tied synthetic braid on a combing board.

[0048] Step 4: Tie the center of the hair bundle with the first tie cord 3; preferably, the first tie cord is an elastic rubber band. When tying with a rubber band, the tightness can be adjusted to ensure the stability of the hair bundle, while avoiding excessive tightness that could deform the hair.

[0049] Step 5: At the tying point of the first tying rope 3, fold a bunch of synthetic hair towards the side of the longest hair strand Lb to form a tied and braided hair. The overall outline of the hair is waterfall-shaped, and the bottom of the hair has an outward convex arc shape, an inverted raindrop shape, or a heart-shaped outline.

[0050] See Figure 9 , Figure 10 , Figure 11 Example 3 of the manufacturing method for the first type of synthetic hair bundle of the present invention involves preparing a bundle of synthetic hair, comprising a predetermined 4000-6000 synthetic hair strands, and the manufacturing method includes the following steps: Step 1: Cut the two ends of a bundle of synthetic hair into two parallel bevels (including the left bevel 2.1 and the right bevel 2.2) to form a single bundle of synthetic hair 2 with parallel bevels (e.g., Figure 9 As shown), the included angle of inclination of the left oblique cut surface 2.1 is α, and the included angle of inclination of the right oblique cut surface 2.2 is β, α≠β, α+β=180°, preferably, α is 140° and β is 40°.

[0051] Step 2: Mix and comb the hair strands so that the outlines of both ends of a strand of synthetic hair are in the predetermined mixed shape.

[0052] Step 3: Stretch and comb the two ends of a strand of synthetic hair so that the ends are natural hair tips and the outer edge has a natural outward convex arc shape.

[0053] Step 4: Tie the first tie rope 3 to the center of a bundle of synthetic hair, bend and fold the tie rope at the tying point to form a bundle of synthetic hair with a predetermined outer edge outline, the outer edge outline being a natural outward convex arc shape.

[0054] Step 5: Use the second tie 4 to tie the folded hair bundle at the neck to form a buttonhole 5, forming a bundled hairpiece. The top of the outer edge is in the shape of a buttonhole, and the bottom is a natural outward convex arc shape.

[0055] See Figure 1 , Figure 2 , Figure 11 Example 4 of the manufacturing method for the first type of synthetic hair bundle of the present invention involves preparing a bundle of synthetic hair, comprising a predetermined 4000-6000 synthetic hair strands, and the manufacturing method includes the following steps: Step 1: Cut the two ends of a bundle of synthetic hair into two symmetrically arranged oblique surfaces (including oblique surface 1.1 on the left end and oblique surface 1.2 on the right end), forming a single bundle of synthetic hair 1 with symmetrical oblique surfaces. The angle of inclination of oblique surface 1.1 on the left end is α, and the angle of inclination of oblique surface 1.2 on the right end is β. The angles of α and β are the same, and the angle of inclination of the two oblique surfaces is greater than 20° and less than 90°. The shortest hair strand in the bundle of synthetic hair is La, and the longest hair strand is Lb. 80% ≥ La / Lb ≥ 50%.

[0056] Step 2: Mix and comb the diagonally cut strand of synthetic hair to blend the lengths of the hair strands into the predetermined end profile.

[0057] Step 3: Further stretch and comb the strands on both sides of the synthetic hair to make the strands and ends fluffy and natural.

[0058] Step 4: Tie the first tie rope 3 to the center of the bundle of hair, and bend it at the tie point, folding it towards the longest hair strand Lb to form a tied bundle of hair. The overall outer edge of the bundle is fluffy and natural.

[0059] Step 5: Use the second tie 4 to tie the entire head and neck area, forming a buttonhole 5 at the head, with the lower middle part of its outer edge forming a ponytail shape (as shown). Figure 11 (As shown).

[0060] The synthetic hair used in this invention is made of synthetic fibers or chemical fibers suitable for wig manufacturing.

[0061] See Figure 12 The specific steps of the manufacturing method of the present invention will be described in detail below: Slant Cut (S1): A bundle of synthetic hair with 4000-6000 strands is obtained by slant cutting. The slant cut surfaces at both ends of this bundle of hair form a certain angle with its length direction. The angles α and β of the two opposite sides are both chosen to be 40° (e.g., ...). Figure 1 (as shown), or, the included angle α at one end of the oblique cut is 140°, and the included angle β with the other end is 40° (as shown). Figure 9As shown), to ensure that the hair strands are of equal length, the beveled surfaces at both ends are parallel, and the length of the hair strands extending out presents a continuous gradient change. When both angles α and β are selected as 40°, the shortest hair strand in a bundle of synthetic hair is La, and the longest hair strand is Lb. Preferably, the ratio of the shortest hair strand La to the longest hair strand Lb is 3 / 5 to ensure the overall layering and naturalness of the braid.

[0062] Mixing (S2): Comb the hair on a combing table to mix the hair strands and form a predetermined end profile; this step aims to distribute the hair strands evenly and lay the foundation for subsequent steps.

[0063] Stretching (S3): Further stretch and comb the middle and ends of the tied synthetic braid on a combing table to shape it into a predetermined fluffy and natural outer contour. Preferably, the hair strands are stretched using a heated stretching table, especially the ends, so that the bundle of synthetic hair reaches the predetermined length and the ends form the predetermined tip shape. Through precise stretching and combing operations, the braid is shaped into a predetermined natural outer contour, enhancing the three-dimensionality and realism of the braid.

[0064] Tie (S4): Tie the center of the hair bundle with the first tying rope 3. It is preferable to use an elastic rubber band to tie the hair. When using a rubber band, the tightness can be adjusted to ensure the stability of the hair bundle, while avoiding excessive tightness that could cause the hair to deform.

[0065] Fold in half (S5): Fold the bundle of hair in half at the center of the tie to form a combined braid. Maintain even pressure when folding to ensure the braid is symmetrical on both sides and has an aesthetically pleasing overall shape.

[0066] Tie (S6): Using a second tying cord 4, further tie the entire hair strand at the folded head of the braided hair, forming a buttonhole 5 at the head, thus creating a tied braided hairpiece with a buttonhole 5 at the head. This structure ensures ease of packaging and allows for the display of a specific style.

[0067] Combing (S7): Stretch the bottom of the braid appropriately to form a natural hair tip shape.
