Description

Technical Field

[0001] The utility model belongs to the field of clothing preparation, in particular to a thermal insulation fabric structure and a thermal insulation product having the same. Background Art

[0002] The quilted structure is currently the most common type of thermal clothing structure. It sews the surface layer and the inner layer of the clothing together with thread at predetermined quilting lines, which not only fixes the surface layer and the inner layer together to prevent the thermal fillings (such as down, cotton fiber, etc.) in each quilted grid from leaking into each other, but also forms various grids, patterns or lines on the surface layer through the stitching lines, combining beauty and practicality.

[0003] There are two main methods for sewing down jackets. One is to sew around the inner liner, fill the down and pat it evenly before quilting. The other is to quilt the liner first and then fill the down. However, the quilting structure produced by these two methods has the problem that the internal space near the sewing line is narrow, making it difficult for the down to stay, resulting in hollow or thin down areas (refer to Figure 1 The heat of the human body can easily diffuse outward from the hollow area or the thin fleece area, which seriously affects the warmth-keeping effect of the clothing and needs further improvement. Utility Model Content

[0034] The existing technology has a technical problem that the internal space near the seam line of the quilted structure of the down jacket is narrow, the down cannot stay, and a hollow or thin down area is formed. The heat of the human body can easily diffuse outward from the hollow area or the thin down area, seriously affecting the warmth-keeping effect of the clothing.

[0035] Therefore, the present invention proposes a new technical solution, which will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] Any content not described in detail in this specification belongs to the prior art known to those skilled in the art. In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," and the like, indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely for the purpose of facilitating the description of the utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the utility model. Furthermore, the terms "first," "second," and "third," etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0037] The utility model provides a warm fabric structure, referring to Figure 2 As shown, the thermal insulation fabric structure includes a first fabric layer 10 and a second fabric layer 20, wherein the second fabric layer 20 is arranged on the inner side or the outer side of the first fabric layer 10, and one or more partition strips 30 are connected between the first fabric layer 10 and the second fabric layer 20. The first fabric layer 10, the second fabric layer 20 and the partition strips 30 are connected to form a filling cavity 40 that can be filled with thermal insulation filler. The partition strips 30 are arranged between the first fabric layer 10 and the second fabric layer 20, so that the filling cavity 40 surrounded by the three is different from the filling cavity of the quilted structure in the prior art (refer to Figure 1 Compared with the above (as shown), it is more three-dimensional, eliminates the hollow area or thin fleece area at the quilting, prevents heat from dissipating quickly through this area, and at the same time increases the filling volume of the filling cavity, which can be filled with more thermal insulation fillers, and can further improve the thermal insulation of the fabric structure. The partition tape 30 can be further configured to be flexible, so that it can be connected to the first fabric layer 10 and / or the second fabric layer 20 at a variable angle, and can be tilted accordingly with the movement or activity of the first fabric layer 10 and / or the second fabric layer 20, so as to maintain the flatness and comfort of the fabric structure. The partition tape 30 and the second fabric layer 20 and / or the first fabric layer 10 are a one-piece fabric structure, and the one-piece fabric structure means that all structures are formed as one piece from a whole piece / piece of fabric, as opposed to another method of cutting the same or various fabrics / materials into various fragmented parts in advance and then splicing them together. The partition strip 30 and the second fabric layer 20 and / or the first fabric layer 10 are set as a one-piece fabric structure, which can not only adapt to the material and maximize the use of the fabric, but also eliminate the need for multiple complex fabrics or other materials to be spliced ​​together, eliminate complexity and reduce cutting; and maintain a high degree of overall unity and improve aesthetics. Figure 5 As shown, the partition strip 30 is formed by folding the one-piece fabric in a predetermined area. In this way, when making it, only a simple stacking action is required to form the foldable partition strip 30, which is simple, convenient and easy to operate. Figure 2As shown, the filling cavity 40 can be further filled with a movable thermal filler. This thermal filler can include one or a mixture of down, silk, wool, chemical fiber, and foam particles. The filler is movable within the filling cavity 40. The gaps between the fillers allow for a certain amount of air. Due to the small gaps, air convection is poor, making it difficult for cold air from outside to reach the interior, and conversely, for hot air from inside to escape. This maintains the temperature. This is the same principle behind the thermal insulation of existing down jackets and other thermal products.

[0038] Reference Figure 3 In one embodiment, the partition tape 30 and the second fabric layer 20 are formed into a one-piece fabric structure. The second fabric layer 20 is disposed on the inner side of the first fabric layer 10. In this case, the second fabric layer 20 is the inner layer, and the first fabric layer 10 is the outer layer. The partition tape 30 and the inner layer are formed into a one-piece fabric structure. In other embodiments, the partition tape 30 and the outer layer may also be formed into a one-piece fabric structure, or the outer layer, inner layer, and partition tape may all be formed into a one-piece fabric structure.

[0039] Reference Figure 2-Figure 6 As shown, the partition tape 30 includes a folding edge 301, and a first folding piece 302 and a second folding piece 303 that overlap along the folding edge 301. The folding edge 301 is connected to the first fabric layer 10. One end of the first folding piece 302 away from the folding edge 301 and one end of the second folding piece 302 away from the folding edge 301 are connected to form a connecting end 304. The connecting end 304 is integrally connected to the second fabric layer 20 and the connecting end 304 is a common edge of the partition tape 30 and the second fabric layer 20. More specifically, the folding edge 301 is bonded or sewn to the first fabric layer 10. One end of the first folding piece 302 away from the folding edge 301 and one end of the second folding piece 303 away from the folding edge 301 are also bonded or sewn to form a connecting end 304 (cooperating with Figure 3 and Figure 5 As shown, the first folding piece 302 and the second folding piece 303 are connected at their ends away from the folding edge 301 to form a connecting end 304. The bonding can achieve a seamless and traceless exposed surface of the fabric structure, making it more integrated, simple and unified.

[0040] In one specific embodiment, the folded edge 301 is connected to the first fabric layer 10 by sewing, forming a first connecting seam. The end of the first folded piece 302 away from the folded edge 301 and the end of the second folded piece 303 away from the folded edge 301 are sewn together to form a second connecting seam. The first connecting seam and the second connecting seam respectively penetrate the first fabric layer 10 and the second fabric layer 20. As a result, the connecting seams are visible on both outer sides of the thermal insulation fabric structure (the sides away from the first fabric layer 10 and the second fabric layer 20).

[0041] The present invention also provides a thermal insulation product having the above-mentioned thermal insulation fabric structure, wherein the thermal insulation product is a garment, a quilt, a pillow, a mat, or a sleeping bag, wherein the filling cavity is filled with a thermal insulation filler. When the filling cavity is not filled with the thermal insulation filler, the filling cavity can also be an outer cover structure such as a quilt cover or a pillowcase.

[0042] In a specific embodiment, the thermal insulation product is thermal insulation clothing, and the width of the partition tape 30 is 1.0-2.5 cm, where the width direction refers to the direction from the first fabric layer 10 to the second fabric layer 20 or the second fabric layer 20 to the first fabric layer 10. Such a width facilitates the free tilting of the partition tape 30. Preferably, the width of the partition tape is 1.0-1.5 cm, for example, 1.0 cm, 1.2 cm, 1.25 cm, 1.3 cm, or 1.5 cm. Such a width is approximately one-third to three-quarters of the maximum filling spacing between the first fabric layer 10 and the second fabric layer 20, for example, one-third, one-half, two-thirds, three-quarters, etc., thereby eliminating the hollow area while maintaining a better three-dimensional convex and concave effect. The thickness of the partition tape is preferably 0-3 mm to keep the clothing lightweight.

[0043] The thermal insulation fabric structure provided by the present invention can be prepared by the following preparation method, which comprises the following steps:

[0044] S1, select a whole piece of fabric, bend or fold it to form a first fabric layer 10 and a second fabric layer 20 located inside or outside the first fabric layer 10 (refer to Figure 4 Alternatively, two pieces of fabric are selected as the first fabric layer 10 and the second fabric layer 20 located inside or outside the first fabric layer 10;

[0045] S2, folding the second fabric layer 20 at a predetermined position according to a predetermined width to form a partition strip 30, the partition strip 30 includes a folding edge 301, and a first folding piece 302 and a second folding piece 303 overlapped along the folding edge 301 (refer to Figure 5 As shown, Figure 5 In order to show it more clearly and intuitively, the folded section is shown in an upright state. In actual operation, since the fabric is usually flexible, it is presented in a stacked state);

[0046] S3, connect one end of the first folding piece 302 away from the folding edge 301 and one end of the second folding piece 303 away from the folding edge 301 to form a connecting end 304, and the connecting end 304 is integrally connected to the second fabric layer 20 (refer to Figure 3 shown);

[0047] Specifically, in step S3 , one end of the first folding piece 302 away from the folding edge 301 and one end of the second folding piece 303 away from the folding edge 301 are connected by gluing or sewing to form a connecting end 304 .

[0048] S4, connect the folded edge 301 to the first fabric layer 10 (refer to Figure 6 shown);

[0049] Specifically, in step S4, the connection can be achieved by sewing or gluing. In one specific embodiment, in step S3, the end of the first folded sheet 302 away from the folded edge 301 and the end of the second folded sheet 303 away from the folded edge 301 are sewn together to form a second connecting seam. In step S4, the folded edge 301 is sewn together with the first fabric layer 10 to form a first connecting seam. The first connecting seam and the second connecting seam respectively penetrate the first fabric layer 10 and the second fabric layer 20. As described above, the method provided by the present invention only requires stacking a single piece of fabric, sewing one end together, and sewing the other end to another fabric layer to achieve the thermal insulation fabric structure. This method is simple and easy to operate, convenient to operate, and saves time.

[0050] S5. The partition strip 30, the first fabric layer 10, and the second fabric layer 20 are connected together to form a filling cavity 40 that can be filled with thermal insulation filler.

[0051] On the basis of the above steps, the preparation method may further include:

[0052] Step S6: Fill the filling cavity 40 with thermal insulation filler, and after filling, seal the filling cavity 40 by sewing, gluing, hot pressing, etc.

[0053] Compared with the traditional quilted down jacket mentioned in the background technology, the down jacket prepared by adopting the structure and preparation method of the present invention is less likely to wrinkle at the zipper, is smoother, and the hem is less likely to curl up, causing the actual length of the jacket to be shorter than the expected length.

[0054] Reference Figure 7As shown, by conducting a thermal test comparison test on the down jacket provided by the present invention (marked with the new process in the figure) and the down jacket with the traditional quilting structure mentioned in the background technology (marked with the old process in the figure), it was observed that the surface temperature of the two garments gradually increased during the test. In the first 10 minutes after the test started, the temperature of the armpits and zippers on both garments showed obvious changes. At the sewing machine part on the front of the garment, the old process garment (traditional quilting structure down jacket) began to show a temperature increase, while the new process garment (down jacket with the thermal insulation fabric structure provided by the present invention) showed a relative stability with no significant changes. As the test progressed, at 20 minutes, the temperature of the zipper and armpit of the new process garment continued to rise, and some temperature changes also occurred in the sewing machine part of the abdomen and armpit. In contrast, 20 minutes after the test started, the collar, sleeves and sewing machine part of the old process garment had already significantly heated up. Overall, from the perspective of thermal distribution data, the new process garment showed better thermal insulation performance throughout the test process. Judging from the thermal distribution map and clothing surface temperature data, the new process clothing can better block the conduction of heat in the sewing machine area, thereby achieving better thermal insulation effect and showing better warmth retention performance.
