DETAILED DESCRIPTION

(3) The technical solution of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings, and it is clear that the described embodiments are a part of the embodiments of the present disclosure, and not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without making creative labor fall within the scope of the present disclosure.

(4) In the description of the disclosure, it should be noted that when terms “center”, “top”, “bottom”, “left”, “right”, “vertical”, “horizontal”, “inner”, “outer”, etc. appears, the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, only for the purpose of facilitating and simplifying the description of the disclosure, and not to indicate or imply that the device or element referred to must have a particular orientation, be constructed and operate in a particular orientation, and therefore cannot be construed as a limitation of the present disclosure. In addition, the terms “first”, “second”, “third”, where they appear, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

(5) As shown in FIGURE, the present disclosure provides a preparation method of a gauze-closure hair weft including operations at blocks illustrated herein.

(6) At block S1: providing a hair piece and a glass panel, and laying the hair piece flat and fixing the hair piece on the glass panel. Specifically, before laying and fixing the hair piece on the glass panel, the hair piece is fixed by sewing double stitches on the hair piece with a double stitch machine; and after laying and fixing the hair piece on the glass panel, the hair piece is fixed to the glass panel with a tape (e.g., a crepe paper) to prevent uneven smearing of the adhesive caused by the hair piece sliding in the subsequent process.

(7) At block S2: evenly applying thermoplastic polyurethane (TPU) to the hair piece, and placing the glass panel into an oven and baking at 45-50° C. for three hours to obtain a hair weft strip. In this step, after the TPU is evenly applied to the hair piece, the TPU is scraped flat with a squeegee to eliminate air bubbles.

(8) At block S3: removing the glass panel from the oven to cool down to room temperature.

(9) At block S4: covering the hair weft strip with a first screen, applying TPU evenly to the hair weft strip covered with the first screen, placing the glass panel into the oven and baking at 45-50° C. for three hours, and removing the glass panel from the oven to cool down to room temperature. In this step, a squeegee is used to scrap flat the TPU as it is evenly applied to the hair weft strip. The arrangement of the first screen ensures the toughness of the hair weft strip and increases the product life.

(10) At block S5: applying TPU evenly to the hair weft strip, placing the glass panel into the oven and baking at 45-50° C. for three hours, and removing the glass panel from the oven to cool down to room temperature.

(11) At block S6: applying TPU evenly to the hair weft strip, placing the glass panel into the oven and baking at 45-50° C. for five hours, and removing the glass panel from the oven to cool down to room temperature.

(12) At block S7: repeating step S6 twice to obtain a first single-layer hair weft.

(13) At block S8: repeating steps S1-S7 to obtain a second single-layer hair weft.

(14) At block S9: placing the second screen on the glass panel, fixing the first single-layer hair weft and the second single-layer hair weft to the second screen with TPU side by side without gaps, and placing the glass panel into the oven for three hours to obtain the gauze-closure hair weft.

(15) Preferably, step S9 further includes: before the fixing the first single-layer hair weft and the second single-layer hair weft to the second screen with TPU side by side without gaps, cutting the first single-layer hair weft and the second single-layer hair weft to a height of 0.4-0.5 mm respectively. Compared with the common wig products on the market, the present disclosure provides a gauze-closure hair weft with a substantially reduced thickness, which can be controlled between 0.4-0.6 mm depending on the weight, amplitude, and length.

(16) The preparation method of a gauze-closure hair weft provided by the present disclosure includes the following steps: step S1, providing a hair piece and a glass panel, and laying the hair piece flat and fixing the hair piece on the glass panel; step S2, evenly applying thermoplastic polyurethane (TPU) to the hair piece, and placing the glass panel into an oven and baking at 45-50° C. for three hours to obtain a hair weft strip; step S3, removing the glass panel from the oven to cool down to room temperature; step S4, covering the hair weft strip with a first screen, applying TPU evenly to the hair weft strip covered with the first screen, placing the glass panel into the oven and baking at 45-50° C. for three hours, and removing the glass panel from the oven to cool down to room temperature; step S5, applying TPU evenly to the hair weft strip, placing the glass panel into the oven and baking at 45-50° C. for three hours, and removing the glass panel from the oven to cool down to room temperature; step S6, applying TPU evenly to the hair weft strip, placing the glass panel into the oven and baking at 45-50° C. for five hours, and removing the glass panel from the oven to cool down to room temperature; step S7, repeating step S6 twice to obtain a first single-layer hair weft; step S8, repeating steps S1-S7 to obtain a second single-layer hair weft; step S9, placing the second screen on the glass panel, fixing the first single-layer hair weft and the second single-layer hair weft to the second screen with TPU side by side without gaps, and placing the glass panel into the oven for three hours to obtain the gauze-closure hair weft. The present disclosure provides a preparation method of a gauze-closure hair weft, which significantly reduces the thickness of the hair weft and makes it more natural and comfortable for the user to wear, and by using the gauze-closure structure, it can reduce the phenomenon of opening and breaking of the product and greatly improve the service life of the product.
