[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shruff constituent material, and more particularly to a shruff constituent material for forming a shruff used in summer or warm regions.

[0002]

[Prior art]

 Conventionally, a sleeping bag has a heat insulating material such as cotton wool, synthetic fiber cotton (feathered cotton) or feather between the front and back sheets. Further, in such a heat insulating material, various improvements have been made to materials and structures in order to improve its heat insulating function, hygroscopicity, bulkiness (cushioning property) and the like. However, in general, the shruff constituents are required to have contradictory functions of preventing stuffiness and sweat in the summer and exhibiting a high heat retaining effect in the winter, so that both requirements are sufficiently satisfied. I couldn't.

Further, in the conventional heat insulating material, if coarse cloth or the like is used for the front sheet and the back sheet, the cotton fibers and the feathers fly out through the gaps in the cloth, which is not preferable in terms of appearance or skin feel. There was a problem.

[0004]

[Problems to be solved by the device]

 The present invention has been made in order to solve these problems, and even when it is used in the summer or warm regions, it prevents stuffiness and sweat, and has good hygroscopicity, heat retention, and bulkiness. It is an object of the present invention to provide a shroud constituent material in which these characteristics do not deteriorate due to pressing or the like during use.

[0005]

[Means for Solving the Problems]

 The shroud component of the present invention is constructed by providing a heat insulating material layer on the back surface of the front sheet and laminating a mesh material on the back surface, and the layer of the heat insulating material layer in contact with the mesh material is made of synthetic fiber cotton. It is characterized by being formed of a layer of synthetic fiber-treated cotton having bulkiness by applying or spraying an adhesive resin liquid or powder.

[0006]

[Action]

 In the shroud component of the present invention, the heat insulating layer coats or sprays the adhesive resin liquid or powder on the synthetic fiber cotton to bond the fibers, so that the fibers may stick out from the gap of the mesh material. Since it is made of a synthetic fiber-treated cotton layer that has no bulk and is bulky, it has good cushioning properties. Furthermore, since the mesh material is provided in the back layer that is in contact with the human body instead of the back sheet such as woven fabric, moisture and heat are dissipated through the through holes of the mesh material, and stuffiness and sweating do not occur. In addition, since the mesh material has a smaller area in direct contact with human skin than ordinary cloth, it does not stick to the skin due to stuffiness and feels good on the skin.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing an embodiment of the shroud constituent material of the present invention.

The shruff constituent material of the embodiment is a synthetic fiber-treated cotton layer 2 on the back surface of a front sheet 1 made of a woven fabric of natural fiber yarns or synthetic fiber yarns, or a mixed woven fabric of these fiber yarns. It is provided as a layer, and on the back surface thereof, a mesh material 3 such as a net, a mesh cloth, a mesh resin sheet, a resin sheet or a non-woven fabric, which is a sheet material formed by forming a large number of through holes, is laminated. ing. Synthetic fiber-processed cotton is obtained by applying or spraying a solution or powder of adhesive resin on ordinary synthetic fiber cotton (synthetic cotton), and the adhesive resin adheres to the crimped synthetic fiber. , The complicated entanglement of fibers is fixed by adhesion. As shown in FIG. 2, the front sheet 1, the synthetic fiber-treated cotton layer 2 and the mesh material 3 are sewn together 4 by such a shruff constituent material so that the mesh material 3 is located on the back surface. Sewage is sewn to form the shruff 5. FIG. 3 is a sectional view taken along line XX ′ of FIG. In the shruff constituent material of the embodiment configured as described above, since the mesh material 3 having a large number of through holes and having a small contact area is provided in the back layer which is in direct contact with the human body, the mesh material is protected from moisture and heat. It diffuses through the through holes of the material 3, and it does not cause stuffiness or sweating even in the summer or warm regions, and it feels good on the skin. Also, as a heat insulating material, synthetic fiber-processed cotton, in which adhesive resin liquid, etc. is adhered to synthetic fiber cotton, and the crimping and entanglement of synthetic fibers are fixed by adhesion, is used, so the restoration is good. However, even if it is pressed by the body weight during use, it will be quickly restored to its original shape when the external pressure is removed. Therefore, the heat insulating material layer does not become settled, and good hygroscopicity, heat insulating property, cushioning property, etc. are maintained for a long period of time. Further, since the entanglement of the synthetic fibers is fixed by adhesion in this way, the fibers do not jump out from the through holes of the mesh material 3, and the appearance and the texture are good.

In the above embodiments, an example in which the heat insulating material layer is composed only of the synthetic fiber-treated cotton layer 2 has been described, but the shruff constituent material of the present invention is not limited to such a structure. Alternatively, as shown in FIG. 4, the heat insulating material layer may have a two-layer structure of the synthetic fiber-treated cotton layer 2 and the normal synthetic fiber cotton layer 6. That is, even if the synthetic fiber cotton layer 6 is provided on the back surface of the front sheet 1 and the synthetic fiber-treated cotton layer 2 is provided through this layer, sufficient shape restoration is achieved and good hygroscopicity, It retains heat and cushions for a long time. Further, as shown in FIG. 5, the heat insulating material layer has a two-layer structure of a synthetic fiber-treated cotton layer 2 and a normal synthetic fiber cotton layer 6, and a metal foil or a metal is provided between these layers. A reflective sheet 7 such as a vapor deposition resin sheet may be interposed. In the case of such a structure, the cold air that has passed through the front sheet 1 is not reflected to the outside by the reflective sheet 7 and does not permeate to the back side, and due to the body temperature that has passed through the mesh material 3 on the back side. Since the warm air is less likely to be reflected to the inside by the reflective sheet 7 and escape to the outside, a higher heat retaining effect can be obtained.

[0011]

[Effect of device]

 As described above, according to the shruff constituent material of the present invention, it is possible to manufacture a shruff that has good skin feel and does not cause sweating or stuffiness even when used in the summer or warm regions. Further, the constituent material of the present invention has excellent restorability, and good hygroscopicity, heat retention, cushioning properties, etc. are maintained for a long period of time. Furthermore, in the case of uniform height, compared to the case of using only conventional cotton, a small amount is required and it is economical.
