Abstract
Description
[Technical Field]
[0001] The present invention relates to a comforter. [Background technology]
[0002] A feather duvet, which is one type of comforter, can be made lighter while having a thicker layer than other comforters made of cotton or wool, and therefore has high thermal insulation properties. Due to this thermal insulation property, a feather duvet has the characteristic of having excellent heat retention. Usually, the more feathers used in a feather duvet, the greater the volume of the duvet, and therefore the better the heat retention properties. Summary of the Invention [Problem to be solved by the invention]
[0003] However, because feathers are more expensive than cotton or wool, increasing the amount of feathers used is problematic from a cost perspective. If the amount of feathers used is reduced to cut costs, the duvet will become thinner, resulting in a lower heat retention.
[0004] Therefore, an object of the present invention is to provide a comforter that has excellent heat retention while reducing the amount of feathers used. [Means for solving the problem]
[0005] The comforter according to the present invention is a first bedding member; A second bedding member arranged in the stacking direction relative to the first bedding member, The first bedding member includes a cotton-like material, The second bedding member contains feathers, The flocculent material includes powdered lava.
[0006] With this configuration, the first bedding member is made of cotton and the second bedding member is made of feathers, which reduces the amount of feathers used compared to when all bedding members in a quilt are made of feathers. Furthermore, since the cotton contains powdered lava, the far-infrared rays emitted from the powdered lava can raise the perceived temperature of the user of the quilt. Furthermore, since the second bedding member is made of feathers and the first and second bedding members are arranged in the stacking direction, the body warmed by the far-infrared rays is insulated from the outside air by the feathers of the second bedding member, providing excellent heat retention.
[0007] The comforter is The flocculent material is formed in a sheet shape.
[0008] With this configuration, the cotton is formed into a sheet, so the thickness of the layer made of cotton, which is the first comforter component, is uniform. This allows the powdered lava to be distributed evenly across the entire comforter, suppressing unevenness in heat retention performance and providing even better heat retention.
[0009] The comforter is The content of the powdered lava in the cotton-like material is 0.5% by mass or more and 40% by mass or less.
[0010] According to this configuration, since the lower limit of the powdered lava content in the cotton-like material is within the above range, it is easier to ensure the amount of powdered lava that is sufficient to emit far-infrared rays that raise the temperature felt by the user of the quilt, thereby achieving better heat retention. Also, since the upper limit of the powdered lava content in the cotton-like material is within the above range, it is possible to prevent poor molding during the production of the cotton-like material.
[0011] The comforter is The mass ratio of the feathers to the cotton-like material is 1.0 or more and 3.0 or less.
[0012] With this configuration, since the mass ratio of the feathers to the cotton-like material is within the above range, it becomes easier to secure a sufficient amount of feathers to insulate the body, which is warmed by the far infrared rays generated from the powdered lava in the cotton-like material, from the outside air, thereby providing even better heat retention. [Effects of the Invention]
[0013] According to the present invention, a comforter is provided which has excellent heat retention while reducing the amount of feathers used. [Brief explanation of the drawings]
