Description

There is an application for exception of loss of novelty

The present invention relates to a comforter.

Conventionally, a comforter is composed of an outer material and a lining, and batting and feathers arranged between the outer material and the lining. In order to increase the heat retention of the comforter, it is necessary to secure a large amount of air layer formed between the fibers constituting the batting and between the feathers.

Increasing the air layer of the batting and feathers to increase the heat retention of the comforter increases the bulk of the comforter, which takes up space for storage when not in use and does not fit in a household washing machine for washing at home. There is a problem that it cannot be done.

Therefore, it is an object of the present invention to provide a comforter having heat retention and capable of forming a thin thickness thereof.

In order to solve the above-mentioned problems, the present invention has an outer material and a lining, and a heat insulating material having a heat retaining property and an airgel-containing member containing airgel are laminated and provided between the outer material and the lining. It is characterized by that.

The airgel-containing member is formed into a first sheet member in which a member that absorbs moisture and generates heat is formed in a sheet shape, an airgel member that is formed in a sheet shape and contains airgel, and a member that absorbs moisture and generates heat in a sheet shape. The two sheet members may be formed by laminating them in order.

The airgel member may include an airgel-containing foam obtained by mixing and heating a powdery and granular airgel with a thermoplastic polyurethane resin and a foaming agent.

An intermediate sheet to which aluminum is adhered may be provided between the heat insulating material and the airgel-containing member.

The intermediate sheet may be breathable.

The outer material and the lining may be made of a brushed fabric.

According to the present invention, the heat of the heat insulating material is generated by laminating the heat insulating material having the heat retaining property and the airgel-containing member containing the airgel, and the heat is generated by the high heat insulating property of the airgel of the airgel-containing member. Since it can be retained in the heat insulating material and the air layer of the heat insulating material can be less than that of the conventional technique, high heat retaining property can be ensured, so that the thickness of the comforter can be reduced.

FIG. 3 is a partial cross-sectional perspective view showing a state in which the corners of the comforter according to the first embodiment of the present invention are released from sewing. FIG. 1 is a cross-sectional view of FIG. The back view of the intermediate sheet used in the Example of this invention. The vertical sectional view of the comforter which concerns on Example 2 of this invention.

The embodiment for carrying out the present invention will be described with reference to the drawings.

[Example 1]
As shown in FIGS. 1 and 2, the comforter 1 of the first embodiment has an outer material 2, an airgel-containing member 3 containing airgel, an intermediate sheet 4, a heat insulating material 5 having heat retaining properties, and a lining 6, and has a front side. From to the back side, the outer material 2, the airgel-containing member 3, the intermediate sheet 4, the heat insulating material 5, and the lining 6 are laminated in this order. The side on which the user is located will be described as the back side, and the opposite side will be described as the front side.

The outer peripheral portion 2, the airgel-containing member 3, the intermediate sheet 4, the heat insulating material 5, and the lining 6 are hem-processed on the outer peripheral portion thereof, and the comforter 1 is integrally formed.

The outer material 2 and the lining 6 are made of any material such as cotton, polyester, rayon or lyocell. Further, it is preferable to use a brushed fabric as the outer material 2 and the lining material 6.

As shown in FIG. 2, the airgel-containing member 3 is configured by laminating a first sheet member 10, an airgel member 11, and a second sheet member 12.

The first sheet member 10 and the second sheet member 12 are composed of batting in which chemical fiber cotton is formed into a sheet shape. Chemical fiber cotton is cotton produced from chemical fibers, and examples of the chemical fibers of chemical fiber cotton include recycled fibers, semi-synthetic fibers, synthetic fibers, and inorganic fibers, such as polyester, nylon, and polypropylene. It is preferable to use the synthetic fiber of the above, and the fiber of a plurality of materials may be composited. In this embodiment, a member that absorbs moisture and generates heat is used.

The airgel member 11 is formed in a sheet shape and contains powdery and granular airgel, a thermoplastic polyurethane resin, and a foaming agent. Examples of the aerogel include silica aerogel, carbon aerogel, and alumina aerogel. In the present invention, silica aerogel was used. Airgel has extremely low thermal conductivity and high heat insulating properties.

The airgel, the thermoplastic polyurethane resin and the foaming agent are heated to form an airgel-containing foam. As a result, the airgel is not easily broken and is stabilized while having breathability. The effervescent agent may be any as long as it decomposes by heating to generate a gas such as carbon dioxide gas or nitrogen. Azo compounds, sulfonyl hydrazide compounds such as benzenesulfonyl hydrazide and toluenesulfonyl hydrazide, inorganic foaming agents such as sodium bicarbonate can be used, and mixtures thereof and combinations of suitable foaming aids are also available. Can be used.

As shown in FIG. 3, the intermediate sheet 4 is made of a breathable sheet-like member, and in this embodiment, it is made of a taffeta cloth made of 100% polyester. A plurality of aluminum portions 4b to which aluminum is adhered by vapor deposition or the like are formed on the side surface 4a of the lining 6 of the intermediate sheet 4. Between the adjacent aluminum portions 4b and 4b, a ventilation portion 4c is formed in which aluminum is not adhered and is composed only of a sheet-like member, and the ventilation portions 4c are formed in a grid pattern as shown in FIG.

If a plurality of aluminum portions 4b are formed on the side surface 4a of the lining 6 of the intermediate sheet 4 and a ventilation portion 4c is formed between the adjacent aluminum portions 4b and 4b, the shapes of the aluminum portion 4b and the ventilation portion 4c are arbitrary. Can be configured in.

The heat insulating material 5 is made of synthetic cotton composed of chemical fibers such as feathers, wool, natural cotton, polyester or nylon or polypropylene, and has a heat insulating property having an air layer formed inside. In this embodiment, feathers are used as the heat insulating material 5, and the feathers are provided between the intermediate sheet 4 and the lining 6 in a state of being stored in a bag of breathable polyester or the like. It does not have to be stored in.

The comforter 1 is breathable and reflects the heat of the heat insulating material 5 by the intermediate sheet 4 to which aluminum is partially adhered, and the heat insulating material is kept by the high heat insulating property of the airgel of the airgel-containing member 3. Since it can be confined in 5, the thickness of the comforter 1 can be made considerably thinner than that of the conventional comforter because high heat retention can be ensured even if the air layer of the heat insulating material 5 is smaller than the conventional one. be able to.

Since the thickness of the comforter 1 can be made considerably thinner than that of the conventional comforter, the storage space when not in use can be made compact, and the comforter 1 can be placed in the washing tub of a household washing machine. You can do the laundry.

Further, since the airgel-containing member 3 is also breathable as well as being breathable through the ventilation portion 4c of the intermediate sheet 4, it is possible to release the moisture inside the heat insulating material 5 to the outside and prevent flocking.

[Example 2]
In the first embodiment, the intermediate sheet 4 is provided, but as shown in FIG. 4, the intermediate sheet 4 may not be provided.

Further, in Example 2, a batting made of polyester was used as the heat insulating material 5.

Since other structures are the same as those in the first embodiment, the description thereof will be omitted.

Also in the second embodiment, the same actions and effects as those of the first embodiment are exhibited.
