Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of clothing production, and specifically relates to a waterproof clothing lap joint structure. Background Art
[0002] In recent years, people's love for outdoor sports has increased year by year, but the outdoor weather is unstable. If it rains or splashes, waterproof clothing is used to prevent the inner clothes from getting wet, such as jackets, which are often used for outdoor and daily wear. Waterproof clothing is often made of waterproof and breathable fabrics, but during the processing of clothing, it is often formed by splicing and overlapping sewing of multiple pieces; because the sewing will produce multiple holes on the waterproof fabric, it will destroy the waterproofness of the waterproof fabric at the overlap, causing rainwater to leak into the clothing; the existing waterproof method is to use waterproof materials to coat or apply them on the outer surface of the overlap. Although it can solve the problem of waterproofing the overlap, it is more obvious in appearance, affecting the appearance of the clothing and reducing the competitiveness of the product. Our company discovered this problem during the production process, so we want to solve it. Summary of the invention
[0003] The purpose of the utility model is to provide a waterproof clothing lap joint sewing structure, which is intended to solve the waterproof clothing.
[0004] To solve the above technical problems, the purpose of the utility model is to achieve this:
[0005] A waterproof clothing overlapping sewing structure includes waterproof fabrics, and is characterized in that a hot melt adhesive film is arranged between two overlapping waterproof fabrics, and the overlapping part is sewn; the overlapping part after sewing is heated to melt the hot melt adhesive film.
[0006] Based on the above-mentioned solution and as a preferred solution of the above-mentioned solution, the hot melt adhesive film is a low-temperature hot melt adhesive.
[0007] Based on the above-mentioned solution and as a preferred solution of the above-mentioned solution, the hot melt adhesive film is a base-free low-temperature TPU hot melt adhesive film.
[0008] Based on the above scheme and as a preferred scheme, the melting point of the hot melt adhesive film is 60-80°C.
[0009] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects: the utility model arranges a hot-melt adhesive film between the fabric layers at the overlapped joint, and then performs sewing, so that the hot-melt adhesive film is sandwiched between the two fabric layers; during the sewing process, the action of the sewing machine will tighten the sewing thread, that is, the fabric layer will be closely attached to the hot-melt adhesive film; the hot-melt adhesive film is melted by heating, and the melted hot-melt adhesive film will fill the pores generated by the sewing, so as to completely avoid or largely solve the leakage problem. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 The schematic diagram of the overall structure of the cuff is shown;
[0011] Figure 2 This is a schematic diagram of the completed sewing status of the cuffs. DETAILED DESCRIPTION
[0012] In order to make the purpose, technical solution and advantages of this application clearer, the technical solution in the embodiment will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of this application, not all embodiments. Based on the given embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0013] In the description of the present application, it should be understood that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.
[0014] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.
[0015] See Figure 1-2 As shown, the present application discloses a waterproof clothing lap joint structure. Specifically, Figure 2The sewing structure of the cuff is shown in the figure, which rolls the waterproof fabric 10 into a cylindrical shape, and then overlaps the first free end 101 and the second free end 102. A hot-melt adhesive film 20 is arranged between the overlapping first free end 101 and the second free end 102, and the overlapping part is sewn by a sewing thread 30; and the overlapping part after sewing is heated to melt the hot-melt adhesive film. During the sewing process, the sewing thread will be tightened by the sewing machine, that is, the fabric layer will be pressed against the hot-melt adhesive film. Then, through the pulling of the sewing thread and the elastic effect of squeezing the fabric, the melted hot-melt adhesive film will fill the pores produced by the sewing, and the pores will be filled and blocked. And due to the elasticity of the hot-melt adhesive film itself, the leakage problem can be completely avoided or solved to a large extent. And because the hot-melt adhesive film is between the fabric layers at the overlapping part, it will not leak out. On the basis of solving the leakage problem, it will not damage the appearance of the clothes themselves. In addition, in Figure 2 After the stitching of the middle lap joint is completed, it is turned inward from the outer surface 10a and the inner surface 10b is turned outward so that the lap joint is located inside the cuff (see Figure 1 ) further hide it to enhance the product's appearance quality.
[0016] Of course, if the melting point of the hot melt adhesive film is too high, it may damage the waterproof fabric when it is heated and melted; for this reason, the hot melt adhesive film in this embodiment is preferably a low-temperature hot melt adhesive. Specifically, the hot melt adhesive film is a substrate-free low-temperature TPU hot melt adhesive film (low-melting-point polyurethane adhesive film), and the melting point of the hot melt adhesive film is 60-80°C. In order to ensure that the hot melt adhesive film is completely melted reliably and improve its fluidity and filling effect, the actual heating temperature is 80-100°C; the tolerance temperature of general waterproof fabrics is often above 150°C, that is, the use of low-temperature hot melt adhesive film will not damage the waterproof fabric of the clothing while achieving melting.
[0017] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
