Description

Technical Field

[0001] The utility model belongs to the field of clothing preparation, in particular to a warm-keeping product. Background Art

[0002] The quilting 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 the 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 quilting grid from mixing with 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 first and then fill the down. However, the quilting structure produced by these two methods has a narrow internal space near the suture line, making it difficult for the down to stay, forming a hollow or thin down area (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 to be further improved.

[0034] In the prior art, there is 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 utility model proposes a new technical solution, which will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0036] The contents not described in detail in this specification belong to the prior art known to the professional and technical personnel in this field. In the description of this utility model, it should be understood that the term " The directions or positional relationships indicated by “center”, “up”, “down”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inside”, “outside”, “clockwise”, “counterclockwise”, etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms “first”, “second”, “third”, etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0037] Embodiment 1:

[0038] Reference Figure 1-Figure 5As shown, the present embodiment provides a thermal insulation product, which may be, for example, clothing, a quilt, a pillow, a mat or a sleeping bag, and includes a first fabric layer 10, a second fabric layer 20 and a partition tape 30, wherein the second fabric layer 20 is arranged on the inner side or the outer side of the first fabric layer 10, and a plurality of partition tapes 30 are arranged at intervals between the first fabric layer 10 and the second fabric layer 20, so as to separate a plurality of filling cavities 40 between the first fabric layer 10 and the second fabric layer 20, and the first fabric layer 10, the second fabric layer 20 and the partition tapes 30 are enclosed, and the filling cavity 40 can be sealed. The filling cavity 40 is filled with a movable thermal insulation filler 401. In the present embodiment, a partition tape 30 is arranged between the first fabric layer 10 and the second fabric layer 20, so that the filling cavity 40 enclosed 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-mentioned fabric (shown in the figure), it is more three-dimensional and eliminates the hollow area or thin fleece area at the quilting to prevent heat from quickly dissipating outward through the area. At the same time, the filling amount of the filling cavity is increased, and more thermal insulation filler 401 can be filled, which can further improve the thermal insulation of the product.

[0039] Specifically, the thermal insulation filler 401 can be down, silk, wool, chemical fiber, foamed particles or a mixture of two or more thereof. It can move in the filling cavity 40 with human body movement or external force. There is a certain amount of air in the gaps between the fillers. Due to the small gaps, the air convection between them is poor, making it difficult for the cold air outside to reach the inside, and conversely, it is not easy for the hot air inside to reach the outside. Thus, the temperature is maintained. This is also the thermal insulation principle of existing thermal insulation products such as down jackets.

[0040] The partition strip 30 is made of flexible fabric, so it can freely tilt toward the filling cavity 40 on the adjacent two sides, improving the comfort of wearing. The partition strip 30 includes a first spacer 301 and a second spacer 302, both ends of the first spacer 301 and the second spacer 302 are respectively connected to the first fabric layer 10 and the second fabric layer 20, and a cavity 303 is formed between the first spacer 301 and the second spacer 302. The partition strip is also provided with a support and pressure structure 50 that can move in the cavity 303, and the support and pressure structure 50 includes a support and pressure strip and / or foaming particles. The material of the support and pressure strip can be fiber or foaming material. A movable supporting and pressing structure 50 is arranged in the cavity 303, which does not destroy the three-dimensionality of the partition belt 30. The supporting and pressing structure 50 including the supporting and pressing strips and / or foamed particles can, on the one hand, improve the thermal insulation of the partition belt 30 area, and on the other hand, can support and press the first spacer 301 and the second spacer 302, thereby generating a force pulling from the middle to both sides. The direction of the force can also change with the movement of the supporting and pressing structure 50 in the cavity 303, so that the partition belt 30 area and other areas of the thermal insulation product are more likely to have a concave-convex height difference, thereby improving the layering of the thermal insulation product, reducing its overall visual heaviness, and integrating warmth preservation with beauty and fashion. The supporting and pressing structure is set to multiple supporting and pressing strips and / or foamed particles, so that each area can be kept warm more evenly through the movement of the supporting and pressing strips or foamed particles. In addition, since the cavity 303 of the partition belt 30 is smaller and the movable range is relatively smaller, the partition belt 30 in areas such as shoulders that are prone to down shedding and causing collapse or lack of warmth (down shedding refers to the connection between the shoulders and the back, and the down in the area is easily accumulated on the back due to gravity) can keep such special areas warm.

[0041] Preferably, the thermal insulation filler 401 is a foamed particle, and the supporting and pressing structure 50 includes the foamed particles, and the particle size of the foamed particles is smaller than that of the foamed particles in the cavity. The foamed particles are polyurethane particles, TPU foamed particles, foam foamed particles or high-ratio supercritical foamed particles, and the material of the foamed particles can be consistent with that of the foamed particles. The filling cavity 40 is filled with foamed particles with a smaller particle size, and the cavity 303 is filled with particles with a larger particle size, so that the supporting and pressing effect is better, and when the first spacer 301 and the second spacer are subsequently connected to the fabric layer by sewing, the particles are not easy to be exposed from the stitching needle holes or gaps, further improving the warmth retention.

[0042] Reference Figure 2 one Figure 5As shown, in this embodiment, the partition strip 30 and the first fabric layer 10 and / or the second fabric layer 20 are a one-piece fabric structure, and the partition strip 30 is formed by folding the one-piece fabric structure. The one-piece fabric structure refers to that all structures are formed as a whole from a whole piece / piece of fabric, which is in contrast to another method of cutting the same or various fabrics / materials into various parts in advance and then splicing them together. Setting the partition strip 30 and the second fabric layer 20 and / or the first fabric layer 10 as a one-piece fabric structure can not only make the best use of the fabric according to the material, but also eliminate the need for splicing of multiple complex fabrics or other materials, eliminate complexity and reduce cutting; it can also maintain a high degree of overall unity and improve aesthetics.

[0043] Cooperate Figure 2 , Figure 3 and Figure 5 As shown, the partition strip 30 includes a folding edge 304, a first spacer 301 and a second spacer 302, the first spacer 301 and the second spacer 302 are overlapped along the folding edge 304, the folding edge 304 is the common edge of the first spacer 301 and the second spacer 302, the folding edge 304 is connected to the first fabric layer 10, one end of the first spacer 10 away from the folding edge 304 and one end of the second spacer 302 away from the folding edge 304 are connected to form a connecting end, and the connecting end is integrally connected to the second fabric layer 20.

[0044] The folded edge 304 and the first fabric layer 10 may be bonded or sewn together, and the end of the first spacer 301 away from the folded edge 304 and the end of the second spacer 302 away from the folded edge 304 may also be connected by bonding or sewing (see Figure 5 As shown, the first spacer 301 and the second spacer 302 in the same partition strip are bonded or sewn at the ends away from the folded edge 304 on the sides close to each other). Bonding can achieve a seamless and traceless exposed surface of the product, making it more integrated and highly concise and unified.

[0045] In a specific example, the folded edge 304 is connected to the first fabric layer 10 by sewing, and the sewing forms a first connecting seam. One end of the first spacer 301 away from the folded edge 304 and one end of the second spacer 302 away from the folded edge 304 are sewn 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. Therefore, the connecting seams can be seen on both outer sides of the thermal insulation product (the two sides away from the first fabric layer 10 and the second fabric layer 20), so that the quilting visual effect can still be seen on the outer sides.

[0049] S3, closing the openings of the filling cavity 40 and the cavity 303.

In actual operation, since the fabric is usually flexible, it is presented in a stacked state);

[0054] S13, connecting (by bonding or sewing) one end of the first spacer 301 away from the folding edge 304 and one end of the second spacer 302 away from the folding edge 304 to form a connecting end, wherein the connecting end is integrally connected to the second fabric layer 20;

[0055] S14, connecting the folded edge 304 to the first fabric layer 10. The connection may be bonding or sewing.
