Description

  The present invention relates to a radiant heat reflection sheet attached to the back side (inner side) of clothes such as air-conditioning clothes and high visibility safety clothes to suppress a temperature rise in the body.

  A conventional air-conditioning suit is a small fan attached to the clothes, which takes outside air into the clothes and vaporizes sweat by flowing a large amount of wind on the surface of the body. In addition, high visibility safety clothes (commonly called: reflective vests) are made to be air-permeable by making the fabric a mesh ground so as to suppress an increase in the surface temperature of the body.

Patent 6278373

In the conventional air-conditioning clothes, small-sized fans take in the outside air into the clothes and drop the body temperature by vaporizing the sweat, but when the outside air temperature exceeds 35 ° C, it becomes almost the same as the body temperature and evaporates the sweat The effect of lowering body temperature is reduced.
In addition, high visibility safety clothes worn on air-conditioning clothes and work clothes are materials that use mesh cloth, but even if the air is well ventilated, radiant heat is directly received on the body such as the back.
The present invention has been made in view of the above-mentioned drawbacks, and by detachably mounting it on the back side (inner side) of clothes such as air conditioning clothes and high visibility safety clothes, it is possible to prevent the influence of external temperature on body temperature. An object of the present invention is to provide a radiant heat reflection sheet.

  In order to achieve the object of the present invention, a device according to claim 1 of the present invention is a radiant heat reflection sheet mounted on the back side of clothes, the radiant heat reflection sheet comprising a heat shield sheet made of an aluminum material and silica. The sheet is characterized in that it is a radiant heat reflection sheet in which the sheet is laminated.

  The invention as set forth in claim 2 is characterized in that the silica sheet is a radiant heat reflecting sheet sandwiched by non-woven fabrics.

  Furthermore, the invention according to claim 3 is characterized in that the radiant heat reflection sheet is a radiant heat reflection sheet in which a knit fabric is attached to a surface in contact with the back side of the clothes.

  According to the invention as set forth in claim 1 of the present invention, radiation heat is reflected to be able to block external heat by wearing it on the back side (inner side) of clothes such as work clothes, etc. It has the effect of reducing the burden on the back part.

  In addition, the silica sheet laminated with the heat shield sheet can prevent odor due to sweat and the like, and can reduce the humidity, and also has an effect of reducing the burden on the wearer physiologically.

  According to the invention of claim 2, in addition to the effect of claim 1, the silica sheet of the radiant heat reflection sheet has a structure in which bead-like silica is sandwiched between non-woven fabrics, so that bead-like silica falls off. There is no effect.

  Furthermore, according to the device of the third aspect, in addition to the effect of the first or second aspect, the radiant heat reflection sheet further reduces the humidity because the knit fabric is attached to the surface in contact with the back side of the clothes. There is an effect that can be done.

The example of the high visibility safety clothes shown as an example of clothes which wear the radiant-heat reflection sheet concerning this invention is shown. The state which turned over the high visibility safety clothes of FIG. 1 is shown. 1 shows an embodiment of a radiant heat reflection sheet according to the present invention. The radiation heat reflective sheet | seat of FIG. 3 is attached to the back side of the back part of the high visibility safety-wear of FIG. The cross section of X-X 'of the radiation heat reflection sheet shown in FIG. 3 is shown.

  FIG. 1 is an example of a high visibility safety suit showing the radiation heat reflective sheet according to the present invention as an example of the clothes to be worn, where a represents a high visibility safety suit, b is a retroreflective material, and c is a fastener. Indicates

  FIG. 2 shows a state in which the high visibility safety clothing a is turned over, and d shows a mesh fabric.

  FIG. 3 shows an embodiment of a radiant heat reflecting sheet e according to the present invention which is cut so as to be able to be attached to the high visibility safety clothes a.

  FIG. 4 shows a state in which a radiant heat reflective sheet e is attached to the back of the high visibility safety clothing a with a double-sided fastener, a button, a double-sided tape or the like on the shoulder portion.

  FIG. 5 is a cross-sectional view taken along line X-X 'of the radiant heat reflective sheet e. The radiant heat reflection sheet e is formed by laminating each sheet of the heat shielding sheet i of aluminum material and the silica sheet h sandwiched by the non-woven fabric j, and further has a surface sheet-like sweat absorption / transpiration function on the side in contact with the body. It is the structure which stuck the knit material f. The total thickness of the radiant heat reflective sheet e is about 1.6 mm.

  I in FIG. 5 indicates a four-layer aluminum sheet, which can reflect radiant heat. By using four aluminum sheets, flexibility and strength can be secured.

  H of FIG. 5 is a silica sheet containing bead-like silica which absorbs odor and moisture, and j is a non-woven fabric for fixing the silica sheet h. Thus, it is possible to prevent the dropout of beaded silica and to prevent odor and reduce the humidity.

  FIG. 5f shows a knit fabric having a sweat absorption / transpiration function, which can further reduce the humidity.

Table 1 shows the results of measurement of the temperature inside the work clothes with the high visibility safety clothes attached, with the radiant heat reflection sheet shown in FIG. 3 of the present invention attached to the back side of the high visibility safety clothes. If the radiant heat reflection sheet is attached, the temperature can be significantly suppressed.
