[0006] Summary of the Invention

[0007] However, in the aforementioned down-filled back-paneled cotton-padded jacket, the down panels need to be sewn together after they are formed. These panels consist of an outer fabric and a lining, which are bonded together by several adhesive strips. The cavities of the outer and lining fabrics are divided into several filling chambers by these adhesive strips, and down is placed inside each chamber. In other words, in this back-paneled cotton-padded jacket, the entire down panel needs to be attached to the jacket as a whole. While this increases warmth, it also increases weight. Especially for sportswear, adding a down panel to a lightweight, quick-drying fabric actually increases drag, making the wearer feel burdened. Furthermore, the manufacturing process requires separately making the jacket and the down panel before sewing them together, making the process complex and increasing material costs.

[0008] This invention was made to solve the above-mentioned problems, and its purpose is to provide a low-cost, simple-to-manufacture, and thinner garment with locally filled thermal insulation material.

[0029] Hereinafter, an example of an embodiment of the present invention will be specifically described with reference to the accompanying drawings. FIG1 is an overall schematic diagram showing a garment with partially filled thermal insulation material according to an embodiment of the present invention, and FIG2 is a schematic diagram showing the adhesive portion of the garment with partially filled thermal insulation material.

[0030] The garment of the present invention has a partially filled insulating material on the garment body. For example, as shown in FIG1, the partially filled insulating material is provided on the back of the garment body; as shown in FIG2, the partially filled insulating material is provided on the front chest area of ​​the garment body; or as shown in FIG3, the partially filled insulating material is provided on the entire front part of the garment body. Specifically, at a predetermined location of the fabric 1 constituting the garment body, the bonding fabric 2 is bonded to the main fabric 1 via an adhesive 3, and a cavity 4 for accommodating the insulating material is divided between the main fabric 1 and the bonding fabric 2 using the adhesive 3. After the main fabric 1 and the bonding fabric 2 are bonded, the insulating material is filled in through the reserved filling hole, thereby providing a partially filled insulating material on the garment body.

[0031] The garment according to the present invention does not require separate down patchwork as in Patent Document 1. Instead, it directly joins and adheres the fabric to the garment body to form a localized warming structure. Its manufacturing process is simple, and the appropriate position can be selected for joining as needed. It is not limited by the position, shape, or size of the required localized warming. Moreover, the resulting garment is lighter and more convenient, making it suitable for sportswear.

[0032] Furthermore, when joining the edges of the main fabric 1 and the bonding fabric 2 and leaving filling holes, the joining area at the edges is preferably joined with a linear adhesive, without the use of sewing thread, thus eliminating the risk of down leakage. Moreover, the fabric will not be damaged by sewing holes, and the sewing holes are not visible, improving the garment's aesthetics and durability. To further reduce the risk of down leakage from the overall filling of the insulating material, the filling holes are also preferably sealed with a linear adhesive after the insulating material is filled.

[0033] Figure 6 shows an enlarged view of the bonding edge between the body fabric and the bonding fabric according to an embodiment of the present invention. As shown in Figure 6, the bonding edge of the bonding fabric 2 is folded inward and inserted between the bonding fabric 2 and the body fabric 1. The folded portion is bonded to both the bonding fabric 2 and the body fabric 1 via adhesive 3, thereby preventing fraying and loose threads at the edge of the bonding fabric 2. Considering the ease of bonding the folded portion, fabric saving, and not affecting the overall appearance, the fold width t1 is preferably 0.3 to 3.0 cm.

[0034] In addition, to improve the sealing and bonding strength at the adhesive edges of the fabric and the bonding material, a covering seal 5 can be further adhered from the outside at the bonding edge of the bonding material 2 and the main body fabric 1. As shown in Figure 7, after the bonding material 2 is adhered to the main body fabric 1, the covering seal 5 is adhered again at their edges. The covering seal 5 is simultaneously adhered to both the bonding material 2 and the main body fabric 1 via adhesive 3. This covering seal 5 is, for example, an adhesive strip (heat-sealing strip for clothing). When using the covering seal 5, the edge of the bonding material 2 does not need to be folded over. The adhesion of the covering seal 5 can cover the edge of the bonding material 2, preventing fraying or loose threads, and can improve the bonding strength between the bonding material 2 and the main body fabric 1, preventing the internal filling material from being exposed from the edge. The material, color, and elasticity of the covering seal 5 are preferably close to those of the main body fabric and / or the bonding material. The covering seal 5 can be adhered along the entire edge of the bonding material 2, or only a portion of the edge can be adhered as needed. Considering factors such as ease of application, resistance to peeling, material saving, and no impact on the overall appearance, the bonding width t2 of the sealing part 5 is preferably 0.5 to 5.0 cm.

[0035] The fabric 1 of the garment body and the bonding fabric 2 of the present invention can be made of the same material or different materials. The bonding fabric 2 can be a lightweight fabric, such as nylon, with a weight generally between 20 and 30 g / m². 2 It possesses good abrasion resistance and down-proof properties; in applications requiring quick-drying properties, the bonding fabric 2 can also be made of polyester fiber, with a weight generally between 40 and 80 g / m². 2Between these two types, the quick-drying performance is better. Typical sportswear often uses lightweight fabrics, and a low-weight bonding fabric 2 is bonded to such a lightweight fabric using only adhesive 3. Even with the weight of the adhesive and insulating materials, the overall weight increase is limited and will not burden the wearer. Furthermore, the overall thickness of the garment will not be excessively increased, making it suitable for situations requiring resistance control, such as movement speed. Other functional fabrics can also be used for the bonding fabric 2, but for suitability for sports, the weight of the bonding fabric 2 is preferably 150g / m². 2 the following.

[0036] The adhesive 3 can be pre-applied to the fabric 1 of the garment body or to the bonding fabric 2. To facilitate the filling of the insulating material and prevent its clumping, this invention preferably allows the adhesive 3 to be arranged according to the desired appearance pattern when dividing the multiple cavities 4 into which the insulating material can be accommodated by the adhesive 3. For example, as shown in Figures 4(a) to (d), it can be arranged intermittently or continuously in a V-shape, or in a wavy or W-shape, etc. The pattern and size of the adhesive 3 can be arbitrarily set as long as the bonding strength and sealing performance are met. However, it is preferable to arrange the adhesive 3 into a pattern that forms uninterrupted connected cavities in at least one direction, as shown in Figure 4(a), forming multiple V-shaped connected cavities; as shown in Figure 4(b), forming multiple W-shaped connected cavities; as shown in Figure 4(c), forming multiple parallel vertical connected cavities; and as shown in Figure 4(d), forming multiple wavy connected cavities. By forming such uninterrupted connected cavities in one direction, compared with grid-like cavities, filling can be faster, which facilitates efficiency when filling thermal insulation materials, saves time, and further reduces manufacturing costs. As shown in Figure 5, the separation points of the multiple cavities 4 can be joined with linear adhesive or with dotted adhesive. Based on the elasticity requirements of sportswear, it is preferable to use dotted adhesive to join the separation points of the multiple cavities.

[0037] In addition, when the area requiring warmth is small and the fabric being applied is small, instead of using adhesive 3 to divide the space into multiple cavities, a single cavity can be formed by joining the edges of the garment fabric and the fabric being applied to accommodate the filling insulation material.

[0038] The preferred size of the adhesive 3 varies depending on the fabric structure and thickness of the garment. If the diameter of the adhesive 3 is approximately 1.0 to 2.0 mm, a strong adhesive strength is easily obtained. However, in thin fabrics, the adhesive 3 may seep to the surface and become noticeable, affecting the appearance. Therefore, it is preferable to have a smaller diameter of the adhesive 3 within the range required to achieve the necessary adhesive strength. For example, in the case of fabrics approximately 0.5 to 0.8 mm thick, an adhesive diameter of 1.0 mm or less is less likely to seep to the surface of the fabric, which is preferable. In the case of even thinner fabrics approximately 0.3 to 0.5 mm thick, an adhesive diameter of 0.6 mm or less results in less noticeable seepage, which is also preferable.

[0039] In this invention, regarding the resin constituting the adhesive 3 used in clothing, synthetic resins are preferred over natural resins, with thermoplastic resins being more preferred. For example, resins formed from polymeric compounds are not particularly limited, except for polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinyl acetate, polyurethane, polytetrafluoroethylene, polyacrylic acid, polyamide, polyacetal, polycarbonate, polyphenylene ether, polyester, polyphenylene sulfide, polysulfone, polyethersulfone, polyetheretherketone, polyimide, polyamide-imide, etc., and various resins can be used.

[0040] It is preferred that the resin constituting adhesive 3 is a reactive hot melt adhesive. When the resin is a reactive hot melt adhesive, the resin softens or melts and penetrates into the interstices of the adhesive area. After cooling and curing, it reacts with the surrounding moisture, thereby cross-linking, and can form an adhesive structure with excellent heat resistance, solvent resistance and washability.

[0041] During the manufacturing process, for example, after the garment body is completed, the bonding fabric 2, which is pre-coated with adhesive according to a specified pattern, is aligned with the specified position of the garment body and joined together. Thus, at the specified position of the garment body, the edge of the bonding fabric 2 is attached to the body fabric 1, and a cavity with a specified pattern is formed between the two. Then, the cavity is filled with insulating material through the reserved filling hole, and after filling is completed, it is sealed to complete the production of the entire garment.

[0042] In addition, in this invention, the main body of the garment is an upper garment, and the designated locations for the partial insulation material to be applied can be the chest, abdomen, shoulders, back, etc., but excluding the arms and armpits. The main body of the garment can also be a lower garment, with the partial insulation material applied to the waist, etc., and there can be one or more application locations. The size of the application location can be set as needed. From the perspective of maximizing warmth retention, it is preferable to apply the material along the center line of the upper body.

[0043] The insulating material used in this invention can be one or more of the following: down, wool, cotton, cotton sheets, synthetic fiber cotton, medium cotton, polyurethane foam, polystyrene foam, etc., selected according to the application scenario of the clothing.

[0044] The present invention will be further described in detail below based on specific embodiments.

[0045] Example 1

[0046] The back is one of the body's important supporting structures, including the spine, scapula, and muscle groups. In cold winters, muscles and joints may experience greater stress and tension, making them prone to stiffness, pain, or injury. Keeping the back warm can reduce muscle and joint discomfort, improve comfort, and lower the risk of injury. For this purpose, as shown in Figure 1, localized insulating material is applied to the back of clothing.

[0047] Adhesive 3 is applied in a V-shape to the areas of the garment fabric 1 to be bonded. In the bonding area where it joins with the edge of the bonding fabric 2, adhesive 3 is applied in a linear pattern, forming a linear bonding portion. In the filling area within the bonding area, adhesive 3 is applied in a dotted pattern, forming a dotted bonding portion. This creates a dotted line partition within the area surrounded by the linear bonding portions. Adhesive may not be applied to the shoulder area initially, serving as a filling hole for the insulation material. After applying the adhesive in the prescribed pattern, the bonding fabric 2 is placed over the body fabric 1 and bonded using a conventional hot press. The bonding fabric 2 is thus bonded to the body fabric 1 via adhesive 3. This creates a space between the bonding fabric 2 and the body fabric 1, surrounded by linear bonding portions, which are then divided into interconnected cavities 4 by the dotted bonding portions. In this design, the two fabrics are not fitted together at the shoulders. These unfitted areas serve as filling holes, through which insulating material is filled. The insulating material fills each cavity individually, preventing clumping. After the required amount of insulating material is filled, adhesive is applied to the filling holes to bond the fabrics together using either linear adhesive or stitching. This completes the garment with fitted insulating material on the back.

[0048] Example 2

[0049] As shown in Figure 2, localized insulating material can also be applied to the front chest area of ​​the garment. First, a rectangular bonding fabric 2 is selected. An adhesive 3 with a prescribed pattern is applied to the side of the bonding fabric 2 to be bonded to the garment fabric. Specifically, linear adhesive 3 is applied to the four edges. In the area surrounded by the edges, adhesive is applied in dots along the long or short sides of the rectangle in a pattern of multiple parallel lines. That is, parallel strip-shaped sections are formed within the area surrounded by the linear joints on the side of the bonding fabric 2 to be bonded to the garment fabric. It should be noted that a portion of the edge of the bonding fabric 2 should be left untreated as a filling opening. Next, the bonding fabric 2 with the prescribed pattern is aligned with the prescribed area of ​​the garment fabric 1 and bonded using a conventional hot press. This creates a space between the bonding fabric 2 and the garment fabric 1, surrounded by linear joints, and this space is divided into interconnected parallel strip-shaped cavities 4 by the dotted joints. Then, insulating material is filled into the pre-drilled filling holes, ensuring that each cavity 4 is filled individually to prevent clumping. After the required amount of insulating material has been filled, adhesive is applied to the filling holes to bond the fabric to the other fabrics using either linear adhesive bonding or stitching. This completes the garment with localized insulating material bonded to the chest area.

[0050] Example 3

[0051] As shown in Figure 3, partial insulating material can be applied to the entire front of the garment as needed. First, adhesive 3 is applied vertically in a straight line to the bonding fabric 2, which is cut to the dimensions of the front of the garment body. That is, linear joints are formed in the joint area where it joins the edge of the garment body fabric 1 and in the filling area of ​​the filling material within the joint area. This creates multiple parallel vertical cavities within the area surrounded by the linear joints, and these cavities are not interconnected. Here, for the subsequent filling of insulating material, the upper or lower edge of the joint area can be left uncoated as a filling hole. After applying the adhesive in the prescribed pattern, the bonding fabric 2 is placed over the body fabric 1 and bonded using a conventional hot press. This bonds the bonding fabric 2 to the body fabric 1 via adhesive 3, thereby creating a space between the bonding fabric 2 and the body fabric 1 surrounded by linear joints, which are divided into separate vertical cavities 4. Then, the areas without adhesive are individually filled with insulating material. After the required amount of insulating material has been filled, adhesive is applied to the filling holes or stitching is used to join the fabric pieces together. This completes the garment with adhesive-backed insulating material on the entire front.

[0052] It should be noted that the adhesive can be applied to either the main fabric 1 of the garment or the bonding fabric 2. The method that is more conducive to the manufacturing process can be chosen based on the actual bonding area and bonding size.
