Description

Technical Field

[0001] This invention belongs to the field of clothing manufacturing, and particularly relates to a thermal insulation fabric structure, thermal insulation products having the same structure, and a method for preparing the same. Background Technology

[0002] Quilted structures are currently the most common type of thermal clothing structure. By sewing the outer and inner layers of the garment together with thread at predetermined quilting points, the outer and inner layers are fixed together, preventing the thermal fillings (such as down, cotton fibers, etc.) in each quilting grid from mixing. At the same time, various grids, patterns, or lines can be formed on the outer layer through the sewing thread, combining aesthetics and practicality.

[0003] Existing down jacket stitching methods mainly include two approaches: one is to sew around the inner lining, fill it with down, pat it evenly, and then quilt; the other is to quilt first and then fill it with down. However, both methods result in a quilted structure where the area near the seam is narrow, making it difficult for down to stay in place, creating hollow or thin down areas (see reference). Figure 1 As shown in area A), human body heat easily dissipates outward from this openwork or thin fleece area, seriously affecting the clothing's warmth retention effect, a problem that needs further improvement. Summary of the Invention

[0004] The purpose of this invention is to provide a thermal insulation fabric structure, a thermal insulation product having the same structure, and a method for preparing the same, in order to overcome the above-mentioned defects in the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A thermal insulation fabric structure comprising:

[0007] First fabric layer;

[0008] The second fabric layer is disposed inside or outside the first fabric layer.

[0009] One or more partition strips are connected between the first fabric layer and the second fabric layer. The partition strips and the second fabric layer and / or the first fabric layer are a one-piece fabric structure. The first fabric layer, the second fabric layer and the partition strips are connected to form a filling cavity that can be filled with thermal insulation filler.

[0010] Furthermore, the filling cavity is filled with movable insulating filler.

[0011] Furthermore, the insulating filler includes one or more of down, silk, wool, chemical fibers, and foamed particles.

[0012] Furthermore, the partition strip is formed by folding the one-piece fabric structure. The partition strip includes a folded edge and a first folded piece and a second folded piece that overlap along the folded edge. The folded edge is connected to the first fabric layer. The end of the first folded piece away from the folded edge and the end of the second folded piece away from the folded edge are connected to form a connecting end. The connecting end is integrally connected to the second fabric layer.

[0013] Furthermore, the folded edge is bonded or sewn to the first fabric layer.

[0014] Furthermore, the end of the first folded piece away from the folded edge and the end of the second folded piece away from the folded edge are bonded or sewn together.

[0015] Furthermore, the folded edge is sewn to the first fabric layer to form a first connecting seam, and the end of the first folded piece away from the folded edge and the end of the second folded piece away from the folded edge are sewn to form a second connecting seam. The first connecting seam and the second connecting seam respectively penetrate the first fabric layer and the second fabric layer.

[0016] Furthermore, the width of the partition strip is 1.0-2.5cm.

[0017] Furthermore, the width of the partition strip is 1.0-1.5cm.

[0018] The present invention also provides a thermal insulation product having the above-mentioned thermal insulation fabric structure, wherein the thermal insulation product is clothing, quilt, pillow, cushion or sleeping bag, and the filling cavity is filled with thermal insulation filler.

[0019] The present invention also provides a method for preparing a thermal insulation fabric structure, which includes the following steps:

[0020] S1. Select a whole piece of fabric, bend or fold it to form a first fabric layer and a second fabric layer located inside or outside the first fabric layer; or, select two pieces of fabric as the first fabric layer and the second fabric layer located inside or outside the first fabric layer, respectively.

[0021] S2. Fold the second fabric layer at a predetermined position and with a predetermined width to form a partition strip. The partition strip includes a folded edge and a first folded piece and a second folded piece that overlap along the folded edge.

[0022] S3. Connect the end of the first folded piece away from the folded edge and the end of the second folded piece away from the folded edge to form a connecting end, and the connecting end is integrally connected to the second fabric layer;

[0023] S4. Connect the folded edge to the first fabric layer;

[0024] S5. The partition strip, the first fabric layer, and the second fabric layer are joined together to form a filling cavity that can be filled with thermal insulation filler.

[0025] Further, in step S3, the end of the first folded piece away from the folded edge and the end of the second folded piece away from the folded edge are sewn together to form a second connecting seam. In step S4, the folded edge is sewn to the first fabric layer to form a first connecting seam. The first connecting seam and the second connecting seam respectively penetrate the first fabric layer and the second fabric layer.

[0026] The beneficial effects of the present invention include at least the following:

[0027] 1. The present invention provides a partition strip between the first and second fabric layers of the thermal insulation product, making the filling cavity formed by the three layers more three-dimensional compared with the filling cavity of the quilted structure in the prior art. This eliminates the hollow area or thin fleece area at the quilting, preventing heat from dissipating outward quickly through this area. At the same time, it increases the filling volume of the filling cavity, allowing for more thermal insulation filler to be filled, which can further improve the thermal insulation of the product.

[0028] 2. In the thermal insulation product provided by the present invention, the partition strip and the first fabric layer and / or the second fabric layer are set as a one-piece fabric structure, and the partition strip is formed by folding the one-piece fabric structure. This not only makes use of the material to its fullest potential, eliminating the need for splicing multiple complex fabrics or other materials, reducing complexity and cutting, and greatly improving the ease of processing; but also maintains a high degree of overall uniformity and enhances aesthetics.

[0042] The existing technology has a technical problem where the area near the seam of the quilted structure of down jackets is narrow, and down cannot stay inside, forming a hollow or thin down area. The body's heat can easily dissipate outward from this hollow or thin down area, which seriously affects the warmth retention of the clothing.

[0043] Therefore, the present invention proposes a new technical solution, and the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] Contents not described in detail in this specification are prior art known to those skilled in the art. In the description of this invention, it should be understood that terms such as "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0045] This invention provides a thermal insulation fabric structure, referring to... Figure 2As shown, the thermal insulation fabric structure includes a first fabric layer 10 and a second fabric layer 20. The second fabric layer 20 is disposed inside or outside the first fabric layer 10. 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 form a filling cavity 40 that can be filled with thermal insulation filler. The partition strips 30 are provided between the first fabric layer 10 and the second fabric layer 20, so that the filling cavity 40 formed by the three layers is similar to the filling cavity of a quilted structure in the prior art (see reference). Figure 1 Compared to the previous version, this design is more three-dimensional, eliminating open or thin fleece areas at the quilting seams to prevent heat from quickly dissipating outwards through these areas. It also increases the filling volume of the filling cavity, allowing for more insulating filler and further improving the fabric's warmth. The partition strip 30 can be further configured to be flexible, allowing it to connect to the first fabric layer 10 and / or the second fabric layer 20 at variable angles. It can tilt accordingly with the movement or activity of the first fabric layer 10 and / or the second fabric layer 20, maintaining the flatness and comfort of the fabric structure. The partition strip 30 and the second fabric layer 20 and / or the first fabric layer 10 form a one-piece fabric structure. This one-piece fabric structure refers to the entire structure being integrally formed from a single piece of fabric, as opposed to a method where different types of fabrics / materials are pre-cut into individual components and then spliced ​​together. By setting the partition strip 30 and the second fabric layer 20 and / or the first fabric layer 10 as a one-piece fabric structure, it can maximize the use of the fabric by making the best use of it, eliminating the need for splicing multiple complex fabrics or other materials, reducing complexity and cutting; at the same time, it can maintain a high degree of overall unity and improve aesthetics. For details, refer to... Figure 5 As shown, the partition strip 30 is formed by folding a predetermined area of ​​the one-piece fabric. This allows for simple stacking during manufacturing, making the folded partition strip 30 easy and convenient to produce. (See reference...) Figure 2 As shown, the filling cavity 40 can be further filled with movable insulating filler. The insulating filler includes one or a mixture of several of the following: down, silk, wool, chemical fibers, and foamed particles. It is placed within the filling cavity 40 and can move within it. The gaps between the filler particles contain a certain amount of air. Due to the small gaps, air convection is poor, making it difficult for cold air from the outside to reach the inside, and conversely, it is difficult for hot air from the inside to escape. This maintains the temperature. This is the insulation principle of existing down jackets and other thermal insulation products.

[0046] Reference Figure 3In one specific embodiment, the partition strip 30 and the second fabric layer 20 are a one-piece fabric structure. The second fabric layer 20 is disposed inside the first fabric layer 10, meaning the second fabric layer 20 is the inner layer and the first fabric layer 10 is the outer layer. The partition strip 30 and the inner layer are a one-piece fabric structure. In other embodiments, the partition strip 30 and the outer layer may also be a one-piece fabric structure, or the outer layer, inner layer, and partition strip may all be one-piece fabric structures.

[0047] Reference Figure 2 Figure 6 As shown, the partition strip 30 includes a folded edge 301, and a first folded piece 302 and a second folded piece 303 overlapping along the folded edge 301. The folded edge 301 is connected to the first fabric layer 10. The ends of the first folded piece 302 and the second folded piece 302 away from the folded 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 the common edge of the partition strip 30 and the second fabric layer 20. More specifically, the folded edge 301 is bonded or sewn to the first fabric layer 10. The ends of the first folded piece 302 and the second folded piece 303 away from the folded edge 301 are also bonded or sewn to form the connecting end 304 (in conjunction with...). Figure 3 and Figure 5 As shown, the ends of the first folded piece 302 and the second folded piece 303 that are away from the folding edge 301 are connected to form a connecting end 304. The bonding can achieve a seamless and traceless exposed surface of the fabric structure, making it more integrated and presenting a high degree of simplicity and uniformity.

[0048] In one specific embodiment, the folded edge 301 is connected to the first fabric layer 10 by a stitch, 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 stitched together to form a second connecting seam. The first and second connecting seams respectively penetrate the first fabric layer 10 and the second fabric layer 20. Therefore, connecting seams are visible on both outer surfaces of the thermal insulation fabric structure (the two surfaces of the first fabric layer 10 and the second fabric layer 20 that are far apart). (Refer to...) Figure 7 As shown, the quilted visual effect is still visible on the outer side.

[0049] The present invention also provides a thermal insulation product having the above-mentioned thermal insulation fabric structure, wherein the thermal insulation product is clothing, quilt, pillow, mattress or sleeping bag, and the filling cavity is filled with thermal insulation filler. When it is not filled with thermal insulation filler, it can also be an outer cover structure such as a duvet cover or pillowcase.

[0050] In one specific embodiment, the thermal insulation product is a thermal garment, and the width of the partition strip 30 is 1.0-2.5 cm. The width direction refers to the direction from the first fabric layer 10 to the second fabric layer 20 or vice versa. This width allows the partition strip 30 to tilt freely. Preferably, the width of the partition strip is 1.0-1.5 cm, for example, 1.0 cm, 1.2 cm, 1.25 cm, 1.3 cm, or 1.5 cm. This width is approximately one-third to three-quarters of the maximum down filling distance between the first fabric layer 10 and the second fabric layer 20, for example, one-third, one-half, two-thirds, or three-quarters. This eliminates the openwork area while maintaining a better three-dimensional texture. The thickness of the partition strip is preferably 0-3 mm to keep the garment lightweight.

[0051] The method for preparing the thermal insulation fabric structure provided by the present invention may include the following steps:

[0052] 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 (see reference). Figure 4 (as shown); or, select two pieces of fabric as the first fabric layer 10 and the second fabric layer 20 located inside or outside the first fabric layer 10, respectively.

[0053] S2. Fold the second fabric layer 20 at a predetermined position and according to a predetermined width to form a partition strip 30. The partition strip 30 includes a folded edge 301, and a first folded piece 302 and a second folded piece 303 overlapping along the folded edge 301 (see reference). Figure 5 As shown, Figure 5 To make the demonstration more intuitive and obvious, the folded sections are shown in a more vertical position. In actual operation, since the fabric is usually flexible, it will be presented as a stacked state.

[0054] s3. Connect the end of the first folded piece 302 away from the folding edge 301 and the end of the second folded piece 303 away from the folding edge 301 to form a connecting end 304. The connecting end 304 is integrally connected to the second fabric layer 20 (refer to...). Figure 3 (as shown);

[0055] Specifically, in step S3, the end of the first folded piece 302 away from the folding edge 301 and the end of the second folded piece 303 away from the folding edge 301 are connected by adhesive or by stitching to form a connecting end 304.

[0056] S4. Connect the folded edge 301 to the first fabric layer 10 (refer to...) Figure 6 (as shown);

[0057] Specifically, in step S4, the connection can be achieved by sewing or gluing. In a specific embodiment, in step S3, 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. In step S4, the folded edge 301 is sewn to 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 piece of fabric, sewing one end together, and sewing the other end to another fabric layer to achieve the thermal insulation fabric structure. It is simple, easy to operate, and saves time.

[0058] S5. The partition strip 30, the first fabric layer 10, and the second fabric layer 20 are joined together to form a filling cavity 40 that can be filled with thermal insulation filler.

[0059] Based on the above steps, the preparation method may further include:

[0060] Step S6: Fill the filling cavity 40 with thermal insulation filler. After filling, seal the filling cavity 40 by means of stitching, gluing, or hot pressing.

[0061] Figure 7 An example of a down jacket prepared using the thermal insulation fabric structure and method provided by the present invention is shown. In the figure, the left side is a down jacket prepared using the thermal insulation fabric structure and method provided by the present invention, and the right side is a traditional quilted down jacket. Compared with the down jacket with the traditional quilted structure mentioned in the background art, the down jacket prepared using the structure and preparation method of the present invention is less prone to wrinkling at the zipper and is smoother, and the hem is less likely to curl, causing the actual length of the garment to be less than the expected length.

[0062] Reference Figure 8As shown, a comparative thermal test was conducted between the down jacket provided by this invention (indicated by the new process) and a down jacket with a traditional quilted structure mentioned in the background art (indicated by the old process). During the test, the surface temperature of both garments gradually increased. In the first 10 minutes of the test, significant temperature changes were observed at the armpits and zipper area on both garments. At the stitched areas on the front of the garments, the old process garment (traditional quilted down jacket) began to show a temperature increase, while the new process garment (down jacket with the thermal fabric structure provided by this invention) remained relatively stable with no significant changes. As the test progressed, at 20 minutes, the temperature at the zipper and armpits of the new process garment continued to rise, and some temperature changes also occurred at the stitched areas on the abdomen and armpits. In contrast, the old process garment showed significant temperature increases at the collar, sleeves, and stitched areas on the front of the garment after 20 minutes of testing. Overall, based on the thermal distribution data, the new process garment demonstrated better warmth retention throughout the entire test. Based on the thermal distribution map and the surface temperature data of the garment, the new process can better block the conduction of heat at the sewing area, thus achieving a better heat insulation effect and exhibiting superior warmth retention performance.

[0063] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
