Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of down fabrics, and particularly relates to a heat preservation structure and a warm clothing. Background Art
[0002] In the design of traditional down jackets, the commonly used sewing process directly fixes and connects the upper and lower layers of fabrics by penetrating them, forming a plurality of channels with flat structures. However, this design has significant limitations: at the sewing joints between the flat structures, due to technical limitations, it is often difficult to fully fill the down, affecting the warmth retention of the down jacket. To overcome this defect, modern down jacket designs have introduced a vertical lining type down channel structure, which creates independent and three-dimensional compartments inside to separate the down filling areas, effectively improving the even distribution of down and the warmth retention performance. However, although the vertical lining type down channel structure performs well in separating the down filling areas, existing designs often neglect the detail treatment of the quilting lines (i.e., the stitches used to sew and fix the vertical linings). There may be no down or uneven down filling at the quilting lines, resulting in accelerated local heat loss and reduced overall warmth retention performance of the down jacket. In addition, the needle holes or sewing gaps at the quilting lines may become channels for down to escape, forming the phenomenon of down leakage. Summary of the Utility Model
[0003] The purpose of the utility model is to overcome the above-mentioned defects or problems existing in the background art, and provide a heat preservation structure and a warm clothing, which solve the problem of poor warmth retention at the quilting lines.
[0004] To achieve the above object, each embodiment of the utility model adopts the following technical solutions but is not limited to the following:
[0005] The first technical solution relates to a heat preservation structure for placing fillers or gases, which includes a first fabric; a second fabric, which is more suitable for being close to the body than the first fabric; a vertical lining, which is connected between the first fabric and the second fabric to divide the space between the first fabric and the second fabric into several first filling cavities, the first filling cavities being suitable for placing fillers or gases. When fillers or gases are placed in the first filling cavities, the vertical lining extends in the thickness direction; the second fabric is provided with a pleat structure, and the pleat structure forms a second filling cavity facing away from the first fabric, the second filling cavity being suitable for placing fillers or gases, and the opening of the second filling cavity is closed to form a closed part facing the first fabric, and the vertical lining is connected to the second fabric at the closed part.
[0006] The second technical solution is based on the first technical solution, wherein a heat preservation space is formed between the cavity walls of two adjacent second filling cavities, and the heat preservation space is provided with a first opening facing away from the first fabric.
[0007] The third technical solution is based on the first technical solution, wherein the closed part is closed by sewing.
[0008] The fourth technical solution is based on the third technical solution. Among them, the standing lining is provided with a connecting portion, the connecting portion includes a first connecting portion and a second connecting portion, the first connecting portion is adhesively connected to the first fabric, and the second connecting portion is adhesively or sewn to the second fabric.
[0009] The fifth technical solution is based on the fourth technical solution. Among them, the standing lining is further provided with an expansion portion. When the first filling cavity is filled with a filler or gas, the expansion portion expands in the thickness direction.
[0010] The sixth technical solution is based on the fifth technical solution. Among them, the cross-sectional shape formed by the connecting portion and the expansion portion is one of U-shaped, N-shaped or Z-shaped.
[0011] The seventh technical solution is based on the fourth technical solution. Among them, the adhesive connection is in the form of brushing glue.
[0012] The eighth technical solution is based on the first technical solution. Among them, both the first fabric and the second fabric are anti-down fabrics.
[0013] The ninth technical solution is based on any one of the first to eighth technical solutions. Among them, a warm clothing uses the above-mentioned warm structure, and the fillers placed in the first filling cavity and the second filling cavity are down.
[0014] As can be seen from the above descriptions of the various embodiments of the present invention, compared with the prior art, the various embodiments of the present invention have the following beneficial effects:
[0015] In the first technical solution and related embodiments, through the combination of the first fabric and the second fabric, and the setting of the standing lining, a closed and separated internal space is formed, including a first filling cavity and a second filling cavity, realizing a three-dimensional composite warm structure of two layers of fabrics. The standing lining is connected between the first fabric and the second fabric. When filled with a filler or gas, it ensures that the filler in the first filling cavity is evenly distributed, improving the warm effect. At the same time, the second filling cavity formed by the pleat structure on the second fabric is directly located directly below the standing lining, reducing the heat loss in the quilting area and forming a warm barrier.
[0016] In the second technical solution and related embodiments, the second fabric is the layer close to the human body. The second filling cavity formed by the pleat structure on it protrudes from the human body, and a heat preservation space is formed between the cavity walls of two adjacent second filling cavities. The excess hot air generated by human movement is stored in the heat preservation space through the first opening, forming an air heat insulation layer, keeping the internal environment of the human body dry and comfortable, and effectively slowing down the speed of heat transfer to the outside, improving the heat retention and warm effect.
[0017] In the third technical solution and related embodiments, the closed part at the opening of the pleated structure is closed by sewing, ensuring the sealing performance of the second filling cavity, preventing the leakage of down, and enhancing the warmth retention effect and durability.
[0018] In the fourth technical solution and related embodiments, there are two embodiments of connection methods provided here. The first is the adhesive connection method, where the connection part is connected to both the first fabric and the second fabric by adhesion. The second is the hybrid connection method. Among them, the first connection part is connected to the first fabric by adhesion, and the second connection part is connected to the second fabric by sewing. Since the first fabric faces the outside and is connected by adhesion, the phenomenon of down leakage can be avoided; and the second connection part can extend to the closed part at the opening of the pleated structure of the second fabric and be directly sewn. At this time, the sewing line corresponds to the second filling cavity. Even if there is down escaping, it enters the second filling cavity, which does not affect the warmth retention effect. This sewing method is more firm than the adhesive connection method.
[0019] In the fifth technical solution and related embodiments, when the first filling cavity is filled with filling material or gas, the stretching part stretches along the thickness direction to isolate the first fabric and the second fabric to form the first filling cavity.
[0020] In the sixth technical solution and related embodiments, the vertical lining with a U-shaped, N-shaped or Z-shaped cross-section provides more flexibility in support to enhance the structural stability.
[0021] In the seventh technical solution and related embodiments, the glue brushing and adhesion method has better sealing performance than the traditional double-sided tape adhesion method, further preventing the leakage of down and enhancing the warmth retention effect. At the same time, the glue brushing method selects the water-based glue process for glue brushing and bonding, achieving the lightness, thinness and softness of the connection, and improving the firmness and durability of the connection, avoiding the disadvantages of heaviness, stiffness and insufficient firmness brought by the traditional glue strip bonding.
[0022] In the eighth technical solution and related embodiments, the main raw materials of the down-proof fabric include pure cotton, polyester or cotton, etc. It is usually woven with a plain weave, and the warp and weft yarns mostly use combed yarns with a smaller linear density value. The main function of this fabric is to prevent down from leaking out of the fabric.
[0023] In the ninth technical solution and related embodiments, the warm clothing adopts the above-mentioned warm structure and has a better warmth retention effect. Both the first filling cavity and the second filling cavity are filled with down, ensuring the overall warmth retention performance of the warm clothing. Description of the Drawings

[0033] See Figure 1 , such as Figure 1 shown, a heat preservation structure includes a first fabric 1, a second fabric 2 and a standing lining 3.
[0034] The first fabric 1, as the outer layer of the structure, is made of a down-proof fabric and has good wind-proof, water-proof and down-proof properties to protect the internal filling from the outside.
[0035] The second fabric 2, as the inner layer of the structure, is more suitable to be close to the body than the first fabric 1. It is made of a down-proof liner fabric, is soft and comfortable, and has good air permeability and warmth retention when contacting the human skin. The second fabric 2 is provided with a pleat structure 4. The pleat structure 4 forms a second filling cavity 6 facing away from the first fabric 1. The second filling cavity 6 is suitable for placing a filling or gas. The opening of the second filling cavity 6 is closed to form a closed part 12 facing the first fabric 1. The standing lining 3 is connected to the second fabric 2 at the closed part 12.
[0036] A heat preservation space 7 is formed between the cavity walls of two adjacent second filling cavities 6. The heat preservation space 7 is provided with a first opening 8 facing away from the first fabric 1. The second fabric 2 is the layer close to the human body. The second filling cavity 6 formed by the pleat structure 4 on it protrudes from the human body. A heat preservation space 7 is formed between the cavity walls of two adjacent second filling cavities 6. The excess heat generated by human movement is stored in the heat preservation space 7 through the first opening 8 to form an air heat insulation layer, keeping the internal environment of the human body dry and comfortable and effectively slowing down the speed of heat transfer to the outside, thus improving the heat retention and warmth preservation effect.
[0037] The standing lining 3 is connected between the first fabric 1 and the second fabric 2 to divide the space between the first fabric 1 and the second fabric 2 into several first filling cavities 5. The first filling cavities 5 are suitable for placing a filling or gas. When the first filling cavities 5 are filled with a filling or gas, the standing lining 3 extends in the thickness direction. The standing lining 3 is made of a down-proof fabric or a down-proof liner fabric, has a good dividing effect and can fit or be sewn well with the first fabric 1 and the second fabric 2. A second filling cavity 6 corresponds to the position directly below each standing lining 3, enhancing the warmth preservation effect.
[0038] The standing lining 3 is provided with an extension part 9 and a connecting part. The extension part 9 and the connecting part are integrally connected to each other. When the first filling cavity 5 is filled with filling material or gas, the extension part 9 extends along the thickness direction, and the extension part 9 and the connecting part form a dividing structure to divide the first fabric 1 and the second fabric 2 to form the first filling cavity 5. The connecting part includes a first connecting part 10 connected to the first fabric 1 and a second connecting part 11 connected to the second fabric 2. The first connecting part 10 is adhesively connected to the first fabric 1, and the second connecting part 11 is adhesively or sewn to the second fabric 2. Specifically, the adhesive connection is in the form of brushing glue. The brushing glue adhesive method has better sealing performance than the traditional double-sided adhesive method, further preventing the leakage of down and enhancing the warmth retention effect. At the same time, the water-based glue process is selected for brushing glue lamination in the brushing glue method, achieving the lightness and softness of the connection, and improving the firmness and durability of the connection, avoiding the disadvantages of heaviness, stiffness and insufficient firmness brought by the traditional glue strip lamination. The two connecting parts are respectively located at both ends of the extension part 9, and the cross-sectional shape formed with the extension part 9 is one of U-shaped, N-shaped or Z-shaped. The standing lining 3 with different cross-sectional shapes provides more flexibility in support to enhance the structural stability.
[0039] There are the following two embodiments for the connection methods of the connecting part with the first fabric 1 and the second fabric 2.
[0040] Embodiment 1
[0041] The first is the brushing glue connection method, and the brushing glue method is adopted for the connection between the connecting part and the first fabric 1 and the second fabric 2.
[0042] Embodiment 2
[0043] The second is the hybrid connection method. Among them, the first connecting part 10 is connected to the first fabric 1 by the brushing glue method, and the second connecting part 11 is connected to the second fabric 2 by the sewing method. Since the first fabric 1 faces the outside, the brushing glue method is adopted for connection to avoid the phenomenon of down leakage; and the second connecting part 11 can extend to the opening of the folding structure 4 of the second fabric 2 and be directly sewn. At this time, the sewing line corresponds to the second filling cavity 6. Even if there is down escaping, it enters the second filling cavity 6, which does not affect the warmth retention effect. The sewing method is more firm than the brushing glue method in connection.
[0044] In this embodiment, through the combination of the first fabric 1 and the second fabric 2 and the setting of the standing lining 3, a closed and separated internal space is formed, including the first filling cavity 5 and the second filling cavity 6, realizing the warmth retention structure of the two-layer fabric. The standing lining 3 is connected between the first fabric 1 and the second fabric 2. When filled with filling material or gas, it ensures that the filling material in the first filling cavity 5 is evenly distributed, improving the warmth retention effect. At the same time, the second filling cavity 6 formed by the folding structure 4 on the second fabric 2 is directly located directly below the standing lining 3, reducing the heat loss in the quilting area and forming a warm barrier.
[0045] A warm-keeping garment adopts the above-mentioned warm-keeping structure. The fillers placed in the first filling cavity 5 and the second filling cavity 6 are down, ensuring the overall warm-keeping performance of the down jacket. At the same time, due to the partition design of the two filling cavities, the down is more evenly distributed. The down includes heat-insulating materials such as duck down, goose down or a mixture of duck and goose down.
[0046] If the warm-keeping garment is a down jacket, the first fabric 1 is the outer fabric at this time; if the warm-keeping garment is a windbreaker, the first fabric 1 is the liner, and the second fabric 2 is the lining.
[0047] A preparation method of a warm-keeping structure includes the following steps: Align the first fabric 1 in the above-mentioned warm-keeping structure with the contour line of the cutting pattern paper, use a screen printing plate to brush glue on the first fabric 1, and then hang it to dry naturally; Make the pleated structure 4 with live pleats on the second fabric 2; The second connecting part 11 of the standing lining 3 and the closed part 12 of the pleated structure 4 are connected by sewing to form the second filling cavity 6; Use a fusible interlining machine to perform hot pressing treatment on the connecting parts of the first fabric 1, the second fabric 2 and the standing lining 3 to form the first filling cavity 5.
[0048] In this embodiment, the preparation method uses the standing lining 3 structure, the pleated structure 4 and the fabric brushing glue process to construct a multi-layer composite warm-keeping structure. Among them, the brushing glue process, with its advantages of being light, soft, high in firmness, strong in durability and simple in operation, improves the overall performance of the warm-keeping structure, further improves the production efficiency and reduces the production cost. The multi-layer composite structure overcomes the uneven thickness of the filler at the quilting line, reduces the loss of hot air, and solves the problem of poor warmth retention at the quilting line.
[0049] The above description of the specification and the embodiment is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the inspiration of the present invention or the above-mentioned embodiment, those of ordinary skill in the art, combined with common general knowledge, ordinary technical knowledge in the art and / or the prior art, through logical analysis, reasoning or limited experiments, can obtain modifications, equivalent replacements or other improvements to the embodiment of the present invention or some of its technical features, which should all be included within the protection scope of the present invention.
