A cold protection article 10 according to this embodiment is a jacket provided with a heat insulating material made of down or synthetic fiber on the back side of a fabric. The portion of the fabric forming the cold protection article 10 will be described with reference to FIG. The cold protection article 10 of this embodiment is provided with a first fabric 12, a second fabric 14, and a third fabric 16 being stacked. The first fabric 12 and the second fabric 14 are sewn together with a sewing thread 18. The first stitches 20 formed by the first sewing thread 18 are provided in a substantially straight line, and a plurality of the stitches 20 as a whole of the cold protection article 10 are provided in parallel with each other at substantially equal intervals. The inside of the pair of first stitches 20 is a first heat insulating material storage space 22. Inside the first heat insulating material storage space 22, the first heat insulating material 24 made of down, synthetic fiber, or the like is put in almost equal amounts, or stacked and sandwiched.

  The second fabric 14 and the third fabric 16 are sewn together with a second sewing thread 26. The second stitches 28 formed by the second sewing thread 26 are provided in a substantially straight line, and a plurality of the cold protection articles 10 are provided in parallel with each other. The second seam 28 is parallel to the first seam 20, and one second seam 28 is provided substantially at the center of the pair of first seams 20. The inside of the pair of second stitches 28 is a second heat insulating material storage space 30. Inside the second heat insulating material storage space 30, the second heat insulating material 32 made of down or synthetic fiber is put in almost equal amounts or laminated.

  Next, a down jacket, which is a product of the cold protection article 10 of this embodiment, will be described with reference to FIG. When the first fabric 12 is positioned on the surface of the cold protection article 10, the first fabric 12 is made of a strong material having water repellency and waterproofness. Further, the third fabric 16 is made of a flexible material so that there is no sense of incongruity even when it comes into contact with the body. And the 1st cloth 12, the 2nd cloth 14, and the 3rd cloth 16 are cut into the shape of the front body, the back body, and the sleeve, and are sewn together, and the 1st stitch 20 provided in the surface of the 1st cloth 12 is It is formed along the horizontal direction. An opening / closing member such as a slide fastener is attached to the front center of the body.

  Further, in the second fabric 14 (not shown), the second seam 28 is positioned in parallel to the first seam 20 in the middle of the pair of first seams 20. The first heat insulating material storage space 22 formed by the pair of first stitches 20 and the second heat insulating material storage space 30 formed by the pair of second stitches 28 are located in a state of being shifted by half in the vertical direction. And the 1st heat insulating material 24 located in the 1st heat insulating material storage space 22 and the 2nd heat insulating material 32 located in the 2nd heat insulating material storage space 30 are also located in the state shifted | deviated by the half in the up-down direction.

  According to the cold protection article 10 of this embodiment, since the seam does not penetrate through the front and back of a jacket or the like, it has good heat retention due to high heat insulating properties, and also reliably blocks ventilation and improves cold protection performance. it can. In the vicinity of the first seam 20, the first heat insulating material 24 is sewed to become thin and the heat insulating property is lowered. The thickest part at the center of 32 is located to prevent heat dissipation. The second heat insulating material 32 is sewed and thinned in the vicinity of the second seam 28, and the heat insulating property is lowered. The thickest part of the center of the material 24 is located and covered with each other. The first seam 20 and the second seam 28 are different first sewing thread 18 and second sewing thread 26 and are provided at different positions. Therefore, the needle hole does not penetrate the cold protection article 10 and the needle hole allows ventilation. This also prevents heat transfer from this point.

  The cold protection article of the present invention is not limited to the above embodiment, and the direction of each seam can be changed according to the design, and the positions of the first seam and the second seam do not match. That's fine. Two or more second stitches may be provided between the pair of first stitches. Moreover, you may use for clothes other than a down jacket, and cold protection goods, such as a sleeping bag.

  Next, the test for comparing with the conventional product was performed on the heat retaining property of the cold protection article 10 of the present invention. First, small pieces having the structure shown in FIG. 1 and FIG. 5B were used as samples for the inventive product and the conventional product. Here, in the conventional product shown in FIG. 5B, the heat insulating material 6 has a two-layer structure in order to achieve the same conditions as in the present invention. Each heat insulating material uses a down and is 0.8 g. In the test method, a sample is placed on a heat generating device or the like set to a predetermined temperature, a thermographic photograph is taken after a predetermined time, and a schematic diagram is shown in FIG. Further, the heat radiation temperature and the heat retention rate of the first stitch 20 of the invention and the stitch 5 of the conventional product were measured. The values are shown in Table 1 below.

この試験の結果、発明品は従来品に比べ、縫目からの放熱温度が３℃低いことがわかり、放熱量が少なく、保温率が高いことが確認された。また、サーモグラフティ写真によると、従来品は縫目５の全長にわたって高温部分が幅広く認められたのに対し、発明品は第一縫目２０の一部に高温部分が細く認められる程度であった。

As a result of this test, it was found that the heat release temperature from the stitches was 3 ° C. lower than that of the conventional product, and it was confirmed that the heat release amount was small and the heat retention rate was high. In addition, according to the thermographic photograph, the conventional product showed a wide range of high temperature portions over the entire length of the seam 5, whereas the inventive product was such that the high temperature portion was found to be thin in a part of the first stitch 20. .

  Next, a test was performed in which the heat insulation property of the cold protection article 10 which is the down jacket shown in FIG. 2 was compared with the down jacket having the conventional structure shown in FIG. The test method was worn by a subject, and after a predetermined period of time, a thermographic photograph was taken, and a schematic diagram thereof is shown in FIG.

  As a result of this test, in the conventional product, a hot part where body temperature escapes in a band shape along the seam 5 provided in the horizontal direction is found in the best part and the sleeve part, and heat is dissipated around the seam 5. On the other hand, in the product according to the invention, a high-temperature portion in a band shape is not recognized, and heat dissipation is suppressed.

  From the above two types of tests, it can be seen that the inventive cold protection article 10 has high heat retention, suppresses heat radiation, and has a high cold protection effect.
