Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mat, and more particularly, to a mattress which is light in weight, has a high bulkiness, is excellent in heat retention, and has a good divergence of water absorbed during bedtime. Regarding mats.

[0002]

2. Description of the Related Art A mattress, which is a bedding, is made by wrapping a mattress cotton on a mattress side. As the batting of a general mat, raw cotton (cotton, fallen cotton), synthetic cotton (polyester, acrylic, polypropylene, rayon, or the like), or a mixture thereof is used. Unlike beds, the banquet involves raising and lowering work in a closet. Raising and lowering the brim is not an easy task for weak people such as the elderly. Among the futons, there are lightweight feather futons etc.
The use of such a gaunt makes it easier to raise and lower the gauntlet.

[0003]

However, the weight of a general mat that uses raw cotton for batting is about 6 kg, and the weight of those using raw cotton and synthetic cotton is about 4.5 to 5.5 kg. is there. Raising and lowering the mat with the above weight is not an easy task. Therefore, with the advent of an aging society in the future, there is a long-felt need for a lightweight mat that does not burden the elderly.

[0004] The present inventor has worked on the development of a lightweight mat and has conducted many studies. In order to simply reduce the weight of the mat, the amount of batting should be reduced. However, when the amount of batting is reduced, not only the bulkiness is lost, but also the sleeping comfort is deteriorated and the heat retention is also deteriorated. If cotton is used as batting, it is light and rich in heat retention, but also lacks bulkiness, and cotton is expensive and production costs are high.

The present inventor has reduced the weight without sacrificing bulkiness (in other words, the same bulkiness reduces the weight),
Moreover, as a result of repeated research on the development of a mat with heat insulation, it was found that it was difficult to satisfy the above conditions with a mat with a single layer structure. Further, it was also found that, even when a plurality of battings are layered and directly stacked in a plurality of layers, the respective fibers are entangled and enter each other's layers, resulting in the same state of the structure as a single layer.

SUMMARY OF THE INVENTION An object of the present invention is to provide a mat which is light in weight, has high bulkiness, is rich in heat retention, and has good divergence of water absorbed during bedtime.
