Description

Technical Field

[0001] The present invention relates to the technical field of thermal insulation clothing, and in particular to a down-filled spacer, a down-filled layer structure and a method for manufacturing thermal insulation clothing. Background Art

[0002] The amount of down filling inside a down jacket and the tear resistance of the jacket's surface are important indicators of its thermal insulation performance. Traditional down jackets are quilted, where the outer fabric, down filling, and lining are sewn together using quilting to create a flat, three-layer thermal structure. However, down jackets made with this quilting process can form pinholes in the fabric. When the down jacket is pressed or pulled hard, the down can escape through the pinholes, reducing its thermal insulation performance. Pinholes also reduce the fabric's tear resistance, making it prone to deformation and even cracking during strenuous exercise. Summary of the Invention

[0003] The object of the present invention is to provide a down filling spacer, a down filling layer structure and a method for manufacturing warm clothing, which can improve the structural strength, warmth retention and durability of clothing.

[0004] To achieve this object, the present invention adopts the following technical solutions:

[0005] Filling spacers, including:

[0006] separator;

[0007] A first bonding portion, the first bonding portion is sewn to one end of the partition portion, the first bonding portion has a first bonding surface, and the first bonding surface is used for bonding with the fabric;

[0008] The second bonding part is sewn at the other end of the partition part, and the second bonding part has a second bonding surface, and the second bonding surface is used for bonding with the lining.

[0009] Preferably, the filling spacer includes a threading material, an outer bottom material and an inner bottom material, the threading material includes a first outer joint, a connecting strip and a first inner joint connected to each other, the outer bottom material includes a second outer joint and an outer bend connected to each other, and the inner bottom material includes a second inner joint and an inner bend connected to each other;

[0010] When the outer bend seam is provided at one end of the connecting strip and the inner bend seam is provided at the other end of the connecting strip, the first outer joint and the second outer joint are spliced ​​together to form the first fitting portion, the first inner joint and the second inner joint are spliced ​​together to form the second fitting portion, and the connecting strip, the outer bend and the inner bend constitute the partition portion.

[0011] Preferably, the first fitting portion and the second fitting portion are both provided with rounded corners.

[0012] The filling layer structure includes a fabric, a lining, a filler and a first partition component, wherein the first partition component includes the above-mentioned filling spacer strip;

[0013] Along the first direction, the plurality of down-filled spacers of the first partition assembly are arranged at intervals, and a filling space is formed between two adjacent down-filled spacers of the first partition assembly. The two adjacent filling spaces are connected, and the filler is filled in the filling space.

[0014] Preferably, the down filling layer structure further comprises a second partition component, and the second partition component comprises at least two down filling spacers;

[0015] Along the first direction, at least two of the down-filled spacers of the second partition assembly are spaced apart, and a disconnected partition cavity is formed between two adjacent down-filled spacers of the second partition assembly, and the first partition assembly is arranged in the partition cavity.

[0016] A method for making warm clothing, using the above-mentioned down-filled spacers, comprises the following steps:

[0017] S1. Adhere double-sided adhesive films on the first bonding surface and the second bonding surface;

[0018] S2, sewing the first laminating portion and the second laminating portion to two ends of the partition portion respectively;

[0019] S3. Hot-pressing and bonding the double-sided adhesive films on the first bonding surface and the second bonding surface to the outer fabric and the lining respectively.

[0020] Preferably, the double-sided adhesive film is made of polyurethane hot melt adhesive.

[0021] The beneficial effects of the present invention are:

[0022] The down filling spacer provided by the present invention comprises a partition, a first bonding portion and a second bonding portion, the first bonding portion and the second bonding portion are respectively arranged at the two ends of the partition, and the first bonding portion and the second bonding portion are respectively connected to the fabric and the lining, so that the partition, the first bonding portion and the second bonding portion form a complete partition structure to prevent the down filling between the lining and the fabric from moving; because the first bonding portion and the second bonding portion are respectively adhered to the fabric and the lining, the down filling spacer does not need to be sewn with the lining and the fabric through quilting, so no pinholes will be formed on the lining and the fabric, and down running is avoided to a great extent. The pinhole-free structure improves the tear resistance of the garment. Since the first laminating portion and the second laminating portion are respectively bonded to the outer fabric and the lining through the first laminating surface and the second laminating surface, the connection area between the first laminating portion and the second laminating portion and the outer fabric and the lining is increased, thereby enhancing the connection strength and further improving the tear resistance and structural strength of the garment. Since the first laminating portion and the second laminating portion are both sewn to the partition portion, compared with the integral structure, the connection strength between the first laminating portion, the second laminating portion and the partition portion is enhanced, thereby improving the structural strength and durability of the filling spacer.

[0023] The filling layer structure provided by the present invention includes a fabric, a lining, a filler and a first partition component. The first partition component includes the above-mentioned filling spacers. Since a filling space for filling the filler is formed between two adjacent filling spacers, a filling layer structure with stable and uniform filling can be formed. The filling layer structure has strong tear resistance and structural strength and good durability.

[0024] When using this method for manufacturing thermal clothing, double-sided adhesive films are adhered to the first and second bonding surfaces, the first and second bonding parts are sewn to the two ends of the partition respectively, and finally the first and second bonding parts are connected to the outer fabric and the lining respectively by hot pressing. The down filling spacers can be fixed without quilting or sewing, which avoids the phenomenon of down running at the pinholes and improves the structural strength and durability of the clothing.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0037] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0038] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0039] In the description of this embodiment, terms such as "upper," "lower," "right," and "left" are used to refer to positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0040] like Figure 1 and Figure 2 As shown, the present invention provides a filling spacer, which includes a partition, a first bonding portion and a second bonding portion. The first bonding portion is sewn at one end of the partition, and the first bonding portion has a first bonding surface, which is used to bond with the fabric 100; the second bonding portion is sewn at the other end of the partition, and the second bonding portion has a second bonding surface, which is used to bond with the lining 200.

[0041] In this embodiment, the first laminating portion and the second laminating portion are respectively arranged at the two ends of the partition portion, and the first laminating portion and the second laminating portion are respectively connected to the outer fabric 100 and the lining 200, so the partition portion, the first laminating portion and the second laminating portion constitute a complete partition structure to prevent the down filled between the lining 200 and the outer fabric 100 from moving; since the first laminating portion and the second laminating portion are respectively adhered to the outer fabric 100 and the lining 200, the down filling spacer does not need to be sewn with the lining 200 and the outer fabric 100 through quilting, so no pinholes will be formed on the lining 200 and the outer fabric 100, which greatly avoids the down running. The pinhole-free structure improves the tear resistance of the garment. Since the first laminating portion and the second laminating portion are respectively bonded to the outer fabric 100 and the lining 200 through the first laminating surface and the second laminating surface, the connection area between the first laminating portion and the second laminating portion and the outer fabric 100 and the lining 200 is increased, thereby enhancing the connection strength and further improving the tear resistance and structural strength of the garment. Since the first laminating portion and the second laminating portion are both sewn to the partition portion, compared with the integral structure, the connection strength between the first laminating portion, the second laminating portion and the partition portion is enhanced, thereby improving the structural strength and durability of the filling spacer.

[0042] The structure of the filling spacer can be set according to actual needs, as long as it can separate the down and firmly connect the fabric 100 and the lining 200. Figure 1 and Figure 3As shown, the filling spacer includes a threading material 1, an outer bottom material 2 and an inner bottom material 3, the threading material 1 includes a first outer joint 11, a connecting strip 12 and a first inner joint 13 connected to each other, the outer bottom material 2 includes a second outer joint 21 and an outer bend 22 connected to each other, and the inner bottom material 3 includes a second inner joint 31 and an inner bend 32 connected to each other; when the outer bend 22 is sewn at one end of the connecting strip 12 and the inner bend 32 is sewn at the other end of the connecting strip 12, the first outer joint 11 and the second outer joint 21 are spliced ​​to form a first fitting portion, the first inner joint 13 and the second inner joint 31 are spliced ​​to form a second fitting portion, and the connecting strip 12, the outer bend 22 and the inner bend 32 constitute a partition, wherein the cross-section of the threading material 1 is Z-shaped, and the cross-sections of the outer bottom material 2 and the inner bottom material 3 are both L-shaped; after the three are sewn together, the three form a filling spacer with an I-shaped cross-section, and the two ends of the I-shaped structure are the first fitting part and the second fitting part, which increases the contact area between the filling spacer and the fabric 100 and the lining 200, thereby effectively improving the connection strength between the filling spacer and the fabric 100 and the lining 200, and at the same time, the I-shaped structure can provide certain support to the fabric 100, so that the down filled inside remains fluffy and distributed, thereby ensuring the warmth retention of the clothing.

[0043] The materials used to make the down filling spacers include but are not limited to cotton, blended fabrics, and linen. As long as they can separate the down or other thermal insulation materials filled inside and meet the requirements of light weight, there is no limitation here.

[0044] In order to reduce the weight of the garment and the amount of material used for the filling spacer, the length of the inner bend 32 and the outer bend 22 is smaller than the length of the connecting strip 12. It is only necessary to ensure that the inner bend 32 and the outer bend 22 have an overlapping area with the connecting strip 12. For example, Figure 1 and Figure 3 As shown, A1 and B1 are respectively the length dimensions of the first outer joint 11 and the second outer joint 21 along the first direction, A2 and B2 are respectively the length dimensions of the connecting strip 12 and the outer bend 22 along the height direction, A3 and C1 are respectively the length dimensions of the first inner joint 13 and the second inner joint 31 along the first direction, and C2 is the length dimension of the inner bend 32 along the height direction; the structure and size of the outer bottom material 2 and the inner bottom material 3 are the same. Taking the outer bottom material 2 as an example, A1 is equal to B1 and equal to A3, the length ratio of A2 to B2 is 6:1, and the length ratio of B1 to B2 is 2:1.

[0045] like Figure 4As shown, in order to prevent the first fitting part and the second fitting part from curling due to continuous friction with the filler 300 during use, rounded corners are set at the corners of the first fitting part and the second fitting part; specifically, the ends of the first external joint 11 and the second external joint 21 along the length direction are set to quarter-round corners, and the two are spliced ​​together to form a semi-circular corner, which can greatly reduce the scratches and friction between the first fitting part and the internal filler 300, thereby effectively avoiding the curling of corners, thereby improving the durability and reliability of the filling spacer.

[0046] This embodiment also provides a down filling layer structure, comprising a fabric 100, a lining 200, a filler 300, and a first partition assembly, the first partition assembly comprising the aforementioned down filling strips. Along a first direction, the down filling strips of the first partition assembly are spaced apart, and a filling space is formed between two adjacent down filling strips of the first partition assembly. The two adjacent filling spaces are connected, and the filler 300 is filled in the filling space. Specifically, the filler 300 can be a thermal insulation material such as down, cotton, or wool.

[0047] Furthermore, the filling layer structure also includes a second partition component, which includes at least two filling strips; along the first direction, at least two filling strips of the second partition component are arranged at intervals, and a partition cavity that is not connected to each other is formed between two adjacent filling strips of the second partition component, and the first partition component is arranged in the partition cavity. In this embodiment, the second partition component forms a number of independent and unconnected partition cavities between the fabric 100 and the lining 200. The partition cavities are arranged corresponding to the various movable joints of the human body. The partition cavity can effectively prevent the filler 300 from being driven and squeezed between the lining 200 and the fabric 100, so as to avoid the filler 300 from running when the human body's knees, elbows, shoulders and other parts move, thereby locking the filler 300 to a certain extent; since a first partition component is also provided in each partition cavity, the several filling strips in the first partition component divide the interior of each partition cavity into several connected filling spaces, and the filler 300 is filled in the filling space. The first partition component makes the filler 300 in each partition cavity evenly and stably distributed, thereby ensuring the thermal insulation performance of the filling layer structure.

[0048] This embodiment also provides a method for making warm clothing, using the above-mentioned down-filled spacers, comprising the following steps:

[0049] S1. Apply double-sided adhesive film to the first and second bonding surfaces; S2. Sew the first and second bonding parts to the ends of the partition; S3. Heat-press bond the double-sided adhesive films on the first and second bonding surfaces to the outer fabric 100 and the lining 200, respectively. Using this method for making warm clothing, double-sided adhesive film is applied to the first and second bonding surfaces, the first and second bonding parts are sewn to the ends of the partition, and finally, the first and second bonding parts are connected to the outer fabric 100 and the lining 200, respectively, by heat-press bonding. This secures the down filling spacers without quilting or sewing, prevents down from escaping at the pinholes, and improves the structural strength and durability of the garment.

[0050] Furthermore, the double-sided adhesive film is made of polyurethane hot melt adhesive. In order to reduce weight and facilitate washing, this embodiment uses an ultra-thin polyurethane hot melt adhesive film with a thickness of 0.03mm to adhere the first and second bonding parts. Specifically, the staff first uses a hot press commonly used in this field to heat-press and bond the polyurethane hot melt adhesive to the first and second bonding surfaces at a temperature of 140℃-145℃. After the first and second bonding parts are sewn separately, the hot press is used to heat-press and bond the polyurethane hot melt adhesive on the first and second bonding surfaces to the outer fabric 100 and the lining 200 respectively. Finally, the staff fills the space between the two adjacent filling strips with filler 300 and sews the filling opening to finally produce the warm clothing.

[0051] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
