Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textiles, and particularly relates to a three-dimensional cold-proof structure of a down coat. Background Art
[0002] A down coat is an upper garment filled with down filling, with a large and round shape. Generally, the down content in a down coat accounts for more than half, and some fine feathers can be mixed at the same time. After cleaning the duck down and disinfecting it at high temperature, it is filled into the clothes to make a down coat. Down coats have the best warmth retention. They are mostly worn by people in cold regions and are also commonly used by polar expeditioners.
[0003] Currently, for the detachable down coats on the market, there are only three ways to make the down inner core. Namely, the two-layer method, the three-layer method, and the four-layer method. For example, in the two-layer method: after sewing the down, the down is very easy to run out from the needle holes. Another example is the three-layer method: only after sewing the down in two layers, a layer of fabric is covered on the side close to the body to block the down running out from the needle holes. In addition, the four-layer method: a layer of fabric is covered on each side of the down inner core where the down has been sewn to block the down running out from the needle holes.
[0004] All of the above three methods have their own drawbacks, but they all sew the inner and outer fabrics together with sewing needles, making the connection part into a single layer of cloth. A channel is formed at this part after filling the down. There is no down at this part when filling the clothes. Due to the lack of protection of down at the channel, a cold bridge is formed, and cold air will invade from here, reducing the warmth retention of the down coat. Content of the Utility Model
[0005] The purpose of the utility model is to provide a three-dimensional cold-proof structure of a down coat, aiming to overcome the defects of the prior art and solve the problem that the cold bridge formed by sewing the fabrics affects the warmth retention of the down coat.
[0006] To this end, the utility model provides a three-dimensional cold-proof structure of a down coat, which includes an outer layer piece, an inner layer piece, and several middle connecting layer pieces; one end of the middle connecting layer piece in the width direction is sewn together with the outer layer piece through a first sewing line, and the other end of the middle connecting layer piece in the width direction is laid flat and sewn together with the inner layer piece through a second sewing line; making the middle connecting layer piece in an "S" shape; after filling the down between the outer layer piece and the inner layer piece, the middle connecting layer piece, the outer layer piece, and the inner layer piece form an "H"-shaped three-dimensional cold-proof structure.
[0007] As a preferred technical solution of the present application, one end of the middle connecting layer piece in the width direction is sewn on the outer layer piece through a first sewing line, and the other end of the middle connecting layer piece in the width direction is reversely folded and sewn together with the inner layer piece through a second sewing line; making the middle connecting layer piece folded into the shape of "η".
[0008] As a preferred technical solution of the present application, several of the middle connecting pieces are sewn to the outer piece by a sewing template and a semi-automatic sewing device.
[0009] As a preferred technical solution of the present application, several of the middle connecting pieces are sewn to the outer piece by manual sewing.
[0010] The three-dimensional cold-proof structure of the down jacket provided by the present utility model increases several middle connecting pieces between the outer piece and the inner piece, and after folding the middle connecting pieces into an "S" shape or an "η" shape, they are respectively sewn to the outer piece and the inner piece, so that the middle connecting piece, the outer piece and the inner piece form an "H"-shaped three-dimensional cold-proof structure, avoiding the formation of a channel at the connection of the outer piece and the inner piece, avoiding the formation of a cold bridge, and preventing cold air from invading from here, thereby improving the warmth retention property of the down jacket.
[0011] In addition to the purposes, features and advantages described above, the present application has other purposes, features and advantages. The following will refer to the drawings for a further detailed description of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present application in detail with reference to the drawings and in combination with the embodiments.
[0020] As Figures 1 to 2 shown, the three-dimensional cold-proof structure of the down jacket of the present utility model includes: an outer layer piece 1, an inner layer piece 2, and several middle connecting pieces 3; wherein, the middle connecting pieces 3 are sewn between the outer layer piece 1 and the inner layer piece 2.
[0021] Specifically, one end in the width direction of the middle connecting piece 3 is sewn to the outer layer piece 1 through a first sewing thread 5, and the other end in the width direction of the middle connecting piece 3 is laid flat and sewn to the inner layer piece 2 through a second sewing thread 6; wherein, after the middle connecting piece 3 is sewn to the outer layer piece 1 and the inner layer piece 2, the middle connecting piece 3 is roughly in an "S" shape; when the outer layer piece 1 and the inner layer piece 2 are filled with down, the three form an approximate "H"-shaped three-dimensional cold-proof structure.
[0022] As Figure 2 、 Figure 3 shown, during the process of sewing the middle connecting piece 3 to the outer layer piece 1 and the inner layer piece 2, first sew the corresponding positions of the outer layer piece 1 to the sewing template and close the sewing template; then sew along the sewing thread avoidance groove on the sewing template through a semi-automatic sewing device; wherein, a feeding mechanism and a shearing mechanism are arranged on one side of the sewing head 4 of the semi-automatic sewing device, a roll-shaped middle connecting piece 3 is installed on the feeding mechanism, the sewing head 4 sews the middle connecting piece 3 to the outer layer piece 1 together, and cuts it off through the shearing mechanism, so that multiple middle connecting pieces 3 are evenly sewn to the outer layer piece 1. Another way is to sew multiple middle connecting pieces 3 evenly to the outer layer piece 1 by hand sewing.
[0023] Then, place the outer layer piece 1 on the workbench of the sewing device, and make the middle connecting piece 3 located directly below the sewing head 4. At the same time, fold the movable end of the outer layer piece 1 to one side, so that there is a certain avoidance space between the outer layer piece 1 and the sewing head 4. Finally, sew the inner layer piece 2 in the flat state to the middle connecting piece 3 one by one by hand sewing; after the outer layer piece 1 and the inner layer piece 2 are completely sewn, fill them with down, so as to form an approximate "H"-shaped three-dimensional cold-proof structure.
[0024] The "H"-shaped three-dimensional cold-proof structure can avoid forming a channel at the connection of the outer layer piece and the inner layer piece, avoid forming a cold bridge, and avoid cold air from invading from here, thereby improving the warmth retention of the down jacket.
[0025] As Figures 4 to 5As shown, in another embodiment, in the three-dimensional cold-proof structure of the above-mentioned down jacket, the middle connecting piece 3 can also be folded into the shape of "η", and is respectively sewn to the outer piece 1 and the inner piece 2; wherein, one end of the middle connecting piece 3 in the width direction is sewn to the outer piece 1 through the first sewing thread 5, and the other end of the middle connecting piece 3 in the width direction is reversely folded and sewn to the inner piece 2 through the second sewing thread 6; so that the middle connecting piece 3 is folded into the shape of "η".
[0026] During the process of sewing the middle connecting piece 3 to the outer piece 1 and the inner piece 2, the difference from the previous embodiment is that: after placing the outer piece 1 with multiple middle connecting pieces 3 sewn on it on the workbench of the sewing equipment, the middle connecting piece 3 is reversely folded and placed directly below the sewing head 4. At the same time, the movable end of the outer piece 1 is folded to one side, so that there is a certain avoidance space between the outer piece 1 and the sewing head 4. Finally, the inner piece 2 in the flat state and the middle connecting piece 3 in the reversely folded state are sewn together one by one by manual sewing. After the outer piece 1 and the inner piece 2 are completely sewn, down is filled in, and a three-dimensional cold-proof structure approximately in the shape of "H" can also be formed.
[0027] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
