Description

Technical Field

[0001] This invention belongs to the field of fabric technology, specifically relating to a method for preparing down-proof clothing sheets using a hot-pressing process, the down-proof clothing sheets, and down-proof garments. Background Technology

[0002] Down jackets are garments filled with down feathers, characterized by their lightweight, soft texture, and excellent warmth, making them an indispensable part of winter wear. Most existing down jackets are manufactured through processes such as fabricating garment pieces, sewing down cavities, filling, sealing, and joining. However, the sewn-down-cavity process often results in down jackets leaking out significantly.

[0003] Steel stamping and hot-pressing lines can effectively solve the above problems, but the traditional hot-pressing and gluing process is not only rough in appearance, but also inconvenient to operate, which limits the application of hot-pressing gluing process in the production of down jackets.

[0004] Therefore, developing a method for preparing down-proof garment pieces using a hot-pressing line process that produces down-proof garment pieces with a smooth appearance and fine indentations is of great value. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a method for preparing down-proof garment pieces using a hot-pressing process, as well as the down-proof garment pieces and down-proof garments. This method reduces sewing processes without altering the garment's appearance, and the resulting down-proof garment pieces have highly airtight creases, a very smooth, aesthetically pleasing, and high-end surface, effectively preventing the penetration of water, air, and pollutants. This solves the problem of down leakage through stitching in down jackets, improving the comfort and safety of the garment.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, the present invention provides a method for preparing down-proof garment pieces using a hot-pressing line process, the method comprising the following steps:

[0008] The fabric is made of three-in-one voile fabric and the inner fabric is made of voile fabric. Adhesive is applied to the inner fabric at intervals to form intermittent adhesive strips.

[0009] Preheat the upper template of the high-frequency plastic welding machine;

[0010] The inner material containing spaced adhesive strips is fixed on the lower template of the high-frequency plastic welding machine, and the outer material is laid on the inner material, with the two aligned in the center. Then, the lower template is moved into the main unit of the high-frequency plastic welding machine, and the high-frequency plastic welding machine is started to press the upper and lower templates together to form several indentations, thus obtaining the down-proof clothing piece.

[0011] The present invention provides a method for preparing down-proof fabric using a hot-pressing process. A three-in-one voile base is used as the surface layer, and a voile inner fabric is used as the inner material. Adhesive is applied to the inner material at intervals to form intermittent adhesive strips, the interval between which can be set as needed. The upper template of a high-frequency plastic welding machine is preheated; the preheating temperature can be selected according to the type of adhesive strip and the characteristics of the fabric. The adhesive-coated inner material is fixed on the lower template of the high-frequency plastic welding machine, and the fabric is laid on the inner material, centered and aligned. Then, the lower template is moved into the main unit of the high-frequency plastic welding machine, and the high-frequency plastic welding machine is started, causing the upper and lower templates to press together to form indentations, thus obtaining the down-proof fabric.

[0012] The method provided by this invention eliminates the traditional sewing process, improving processing efficiency and facilitating mass production. Furthermore, the use of a high-frequency plastic welding machine to hot-press the fabric and lining creates highly airtight indentations, effectively preventing water, air, and contaminants from penetrating through these lines. This also better prevents down from escaping through the indentations after filling, solving the risks of down leakage and down slippage during sewing in down jackets, thus significantly improving the comfort and safety of the garment. In addition, the surface of the garment piece formed by hot-pressing the fabric and lining using a high-frequency plastic welding machine is very smooth, aesthetically pleasing, and high-end, giving the finished down jacket a more technologically advanced and high-quality visual appeal, enhancing the overall user experience.

Therefore, they should not be construed as limiting this invention.

[0036] Unless otherwise specified, the raw materials used in the following specific embodiments are all conventional materials in the art and can be purchased from commercially available products.

[0037] Example 1

[0038] A method for preparing down-proof garment pieces using a hot-pressing process is illustrated in the following flowchart: Figure 1 As shown, it includes the following steps:

[0039] Three-in-one tulle base is selected as the fabric 1 and tulle lining fabric is selected as the lining material 2. Adhesive (commonly available glue) is applied to the lining material 2 at intervals of 3cm to form interval adhesive strips 3. The width of each adhesive strip 3 is approximately 0.9cm.

[0040] Start the high-frequency plastic welding machine. The main machine prioritizes heating the upper copper mold. Set the temperature of the upper copper mold to 200℃ to achieve the desired firmness between the fabric 1 and the adhesive strip 3.

[0041] The inner material 2 containing the spaced adhesive strips 3 is fixed on the lower copper mold of the high-frequency plastic welding machine, and the outer material 1 is laid on the inner material 2, with the two aligned in the center. Then, the lower copper mold is moved into the main unit of the high-frequency plastic welding machine, and the high-frequency plastic welding machine is started. The output current of the high-frequency plastic welding machine is 60A. Under the conditions of 200℃ temperature and 6kg air pressure, the upper copper mold and the lower copper mold are pressed together to form an indentation 4 with a width of 0.5mm, thus obtaining the down-proof clothing piece.

[0042] Visually inspect the down-proof garment sheet prepared by the method provided in Example 1. A physical image of the down-proof garment sheet obtained in Example 1 is shown below. Figure 2 As shown;

[0043] from Figure 2 As can be seen, the surface of the downproof clothing sheet provided in Example 1 is very smooth and beautiful, and the indentation is delicate, which can effectively prevent water, air, pollutants and other substances from penetrating through the indentation.

[0044] Example 2

[0045] A method for preparing downproof clothing sheets using a hot-pressing process is disclosed. The only difference between this method and Example 1 is that the pressing temperature is 160°C, while the other steps, conditions, and parameters are the same as in Example 1.

[0046] Similarly, visual observation of the downproof clothing sheet prepared by the method provided in Example 2 shows that the surface of the downproof clothing sheet prepared by the method provided in Example 2 is also very smooth and beautiful, and the indentation is delicate, which can effectively prevent water, air, pollutants and other substances from penetrating through the indentation.

[0047] Example 3

[0048] A method for preparing downproof clothing sheets using a hot-pressing process is disclosed. The only difference between this method and Example 1 is that the pressing temperature is 300°C, while the other steps, conditions, and parameters are the same as in Example 1.

[0049] Similarly, visual observation of the downproof clothing sheet prepared by the method provided in Example 3 shows that the surface of the downproof clothing sheet prepared by the method provided in Example 3 is also very smooth and beautiful, and the indentation is delicate, which can effectively prevent water, air, pollutants and other substances from penetrating through the indentation.

[0050] Example 4

[0051] A method for preparing down-proof clothing sheets using a hot-pressing process is disclosed. The only difference between this method and Example 1 is that the pressing temperature is 100°C, while the other steps, conditions, and parameters are the same as in Example 1.

[0052] Similarly, visual observation of the downproof clothing sheet prepared by the method provided in Example 4 shows that the surface of the downproof clothing sheet prepared by the method provided in Example 4 is also very smooth and beautiful, and the indentation is delicate. However, due to the low pressing temperature (100°C), the adhesive strip cannot be firmly attached to the fabric, the sealing at the indentation is poor, and the problem of down leakage and down running is more likely to occur later.

[0053] Example 5

[0054] A method for preparing downproof clothing sheets using a hot-pressing process is disclosed. The only difference between this method and Example 1 is that the pressing temperature is 350°C, while the other steps, conditions, and parameters are the same as in Example 1.

[0055] Similarly, visual inspection of the down-proof clothing sheet prepared by the method provided in Example 5 reveals that the surface smoothness of the down-proof clothing sheet prepared by the method provided in Example 5 is poor, which is due to the excessively high pressing temperature.

[0056] Application Example 1

[0057] A down-proof garment includes a down-proof garment piece and down provided in Example 1, wherein the down fills the interlayer space formed by the fabric and the lining of the down-proof garment piece.

[0058] Visually inspecting the downproof garment provided in Application Example 1, we obtain the following physical image of the downproof garment provided in Application Example 1: Figure 3 As shown;

[0059] from Figure 3 It can be seen that the downproof garment prepared by further processing the downproof garment sheet obtained by the method provided in Example 1 has a more technological and higher quality visual effect, and no down leakage occurs.

[0060] The applicant declares that this invention illustrates a method for preparing down-proof garment sheets, down-proof garment sheets, and down-proof garments using a hot-pressing process through the above embodiments. However, this invention is not limited to the above embodiments, meaning that this invention does not necessarily rely on the above embodiments for implementation. Those skilled in the art should understand that any improvements to this invention, equivalent substitutions of raw materials for the product, additions of auxiliary components, and selection of specific methods all fall within the protection and disclosure scope of this invention.
