Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a sheet material that can be used for bedding products such as comforters and mattresses, as well as cushions, floor coverings, and chair upholstery.

Conventional technology and its problems The scent of wood has been familiar to people since ancient times, and some scents can make people feel comfortable or have the effect of stabilizing their mental state. For this reason, the fragrant wood is often used to burn incense or put in scent bags. Furthermore, in recent years, so-called forest bathing has been proposed as a good thing for human mental health.

Therefore, it is desirable that items that we use daily, such as bedding products such as comforters and mattresses, as well as cushions, floor coverings, and chair upholstery, have a wood scent.

However, in the past, there were no products of this type that had a woody scent.

Means for Solving the Problems Therefore, the present inventors believe that if there is a sheet-like material in which wood is used as a part of the constituent material and has heat retention and elasticity suitable for use as a material for the futon, etc., the above-mentioned needs can be met. As a result of intensive research, the present invention was completed.

That is, the present invention provides a sheet characterized by comprising a ribbon-like wood layer, an inner material having a wood grain layer on both sides thereof, and a bedding cotton layer on the outer side of each wood grain layer, and an exterior material layer covering the inner material. The purpose is to provide shaped materials.

The above-mentioned ribbon-shaped wood is a thin piece of wood whose length is larger than its width, such as a thin strip or planer shavings with a thickness of about 0.05 to 0.5 mm, and the amount used, each width, The length is appropriately selected so as to give the material of the present invention bulkiness, elasticity, or compressive elasticity depending on the intended use.

In addition, if the particle size of the wood particles is too large, the material of the present invention will feel hard, and if the particle size is too small, there is a risk of scattering to the outside, so the particle size (triaxial average diameter) is preferably about 1 to 4 mm. . The amount of wood particles to be used may be appropriately determined depending on the use of the material of the present invention.

The raw material wood for obtaining the ribbon-like wood layer and the wood grain layer is fragrant, light, and has good hygroscopicity.
It is desirable to use wood that is not too hard and has good insulation properties.
Examples include paulownia, cedar, cypress, and pine.

A suitable breathable sheet is provided between the ribbon-like wood layer and the wood grain layer and between the wood grain layer and the futon cotton layer to prevent the movement of the wood grains to the ribbon-like wood layer and the futon cotton layer. For example, it is desirable to provide a breathable non-woven fabric.

In order to further stabilize the position of the wood grains, appropriate quilting processing can be used, such as a. a breathable sheet placed between the ribbon-like wood layer and the wood grain layer, b. a wood grain layer, and c. a wood grain layer. The three sheets disposed between the futon cotton layer and the futon cotton layer may be combined and quilted, or the futon cotton layer and a breathable sheet provided outside the futon cotton layer may be combined with the five sheets. It may be quilted.

Various futon cottons can be used as the futon cotton, such as those made of natural fibers, those made of chemical fibers such as polyester, polypropylene, acrylic, rayon, etc., or those made of a mixture of natural fibers and chemical fibers. Which futon cotton to use and in what amount may be determined as appropriate depending on the intended use of the material of the present invention.

The exterior material can also be appropriately selected from various breathable fabrics depending on the use of the material of the present invention.

The material of the present invention can be used as it is, after being appropriately cut and sewn together, or in combination with other materials, for bedding products such as quilts and mattresses, as well as cushions, floor coverings, and chair upholstery.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The illustrated sheet material can be used as it is as a mattress, bed mat, etc.

The contents of the sheet material include a ribbon-shaped wood layer 1 at the center, wood grain layers 2 on both sides of the ribbon-like wood layer 1, and a futon cotton layer 3 on the outside of each wood grain layer.

The ribbon-shaped wood layer 1 has a thickness of approximately 0.1 to 0.3 mm and a width of approximately
Ribbon-shaped cypress wood 11, 15-30mm, length approximately 100-500mm
This layer was obtained by using approximately 3.5 to 5 kg per m ² of

The wood grain layer 2 contains wood grains 21 obtained by crushing Japanese cypress and having a particle diameter (triaxial average diameter) of approximately 2 to 3 mm per ¹ m2.
This is the layer obtained using 5 kg.

The futon cotton layer 3 is made of synthetic fiber futon cotton (in this example, polyester futon cotton), and has a density of approximately 60% per ¹ m2.
~70g is used.

Between layer 1 and layer 2, and between layer 2 and layer 3, polyester nonwoven fabrics 4 and 5, which have good air permeability but do not allow wood grains 21 to pass through, are arranged, respectively.

Further, the same nonwoven fabric 6 is provided on the outside of each futon cotton layer 3.

The nonwoven fabric 6, the futon cotton layer 3, the nonwoven fabric 5, the wood grain layer 2, and the nonwoven fabric 4 on each side of the ribbon-like wood layer 1 are combined in advance and subjected to a quilting process K so that they do not fall apart.

In the illustrated embodiment, the quilted bag is sewn together in advance to form a bag, the ribbon-shaped wood 11 is stuffed into the bag, and then the bag opening is closed.

Both outside sides of the contents are covered with a breathable ordinary outer cover cloth 7 for a mattress.

This sheet-like material has a ribbon-like wood layer 1 obtained from Japanese cypress and a wood grain layer 2 inside, so the whole body has the scent of Japanese cypress, and this sheet-like material is used for futons and pine. In some cases, it can make users who like the scent of cypress feel comfortable, and for some people, it can also be expected to have a sound sleep effect.

In addition, since such a sheet material uses wood for its content, it has excellent hygroscopicity and moisture release properties when drying, and furthermore, the wood itself has heat retention properties and the ribbon-like wood 11 between each other and the wood grains 21 Due to the voids between them and the futon cotton layer 3, the whole has excellent heat retention, and even though wood is used for the inside, the ribbon-like wood layer 1 and the futon cotton layer 3 give the whole a desirable elasticity or compression. It is elastic and has appropriate hardness because it is made of wood grains, making it suitable for making mattresses and mats.

If necessary, a ribbon-shaped material or wood grains made of other wood may be used in place of the cypress, or may be made of cypress and other wood.

Effects of the Invention As described above, according to the present invention, not only does it smell like wood, but it also has excellent hygroscopicity and water release properties when drying, and has excellent heat retention, and is also good considering that wood is used for the interior. It can provide sheet materials that have appropriate elasticity and can be used for bedding products such as comforters and mattresses, cushions, floor coverings, and upholstery for chairs.
