Abstract

PROBLEM TO BE SOLVED: To heighten hygroscopic property (water absorption) to favorably absorb sweat or the like and to secure comfortable feeling of use by using forming material containing specified amounts of cellulose acetate, starch, CaCo3 or talc as a filling material for a pillow to be packed in a cloth bag. SOLUTION: A pillow 20 is manufactured by packing a lot of filling material 10 for the pillow made of a biodegradable resin in the inside of a cloth bag 21. Cotton having god hygroscopicity is used as a raw material for the cloth bag 21. A forming material containing 40-90 pts.wt. cellulose acetate, 10-20 pts.wt. of starch containing 1-8 wt.% water, and 5-25 pts.wt. of CaCo3 or talc is used as the filling material for a pillow. The forming material is formed like a cylinder, preferably having a cavity in the interior by extrusion molding using an extrusion molding machine, and the surface of the outside has high roughness to be rough to the touch. The pillow thus formed can effectively absorb sweat or the like provide comfortable feeling of use.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a pillow and a pillow filling.

[0002]

2. Description of the Related Art As a pillow filler for pillows, buckwheat hulls, cotton, feathers and the like have been used for a long time, and the pillows are packed in cloth bags made of cotton or the like.

[0003] Recently, as a filler for pillows, a small cylindrical body made of a synthetic resin such as polyethylene or polypropylene (hereinafter sometimes referred to as a macaroni-type pillow filler).
A large number of such macaroni-type pillow fillers are packed in a cloth bag in the same manner as described above, and provided in a pillow shape.

[0004]

However, the above-mentioned synthetic resin-filled pillow for pillows of macaroons can ensure a certain degree of air permeability due to the hollow inside the macaroni-shaped pillows, but the synthetic resin-filled pillows itself have a hygroscopic property. However, there is a problem that the pillow becomes sticky due to sweating during use of the pillow and gives discomfort. For example, polyethylene has a water absorption of 0.015% and polypropylene has a water absorption of 0.01%. Thus, in the case of a macaroni-type pillow filler having a very low water absorption, even if the above-mentioned cloth bag is made of cotton having good hygroscopicity, etc. However, the cloth bag alone cannot absorb sweat and cannot avoid sticky pillows. Then, in this invention, it aims at providing the pillow excellent in hygroscopicity.

[0005]

The pillow according to the present invention is a pillow in which a large number of pillow packings are packed in a cloth bag, wherein the pillow packing comprises 40 to 90 parts by weight of cellulose acetate, and a water content. 1
A molding material (hereinafter sometimes referred to as a biodegradable resin pillow filler) containing ８8% by weight of starch: 10 to 20 parts by weight, and CaCO ₃ or talc: 5 to 25 parts by weight, respectively. Is the gist.

The pillow filling according to the present invention comprises cellulose acetate: 40 to 90 parts by weight, starch having a water content of 1 to 8% by weight: 10 to 20 parts by weight, CaCO ₃ or talc: 5 to 5 parts by weight.
The gist is that a molding material containing 25 parts by weight is molded (biodegradable resin pillow filler).

[0007] The biodegradable resin pillow filler exhibits good water absorption (hygroscopicity) because the cellulose acetate contained therein has water absorption. And since the biodegradable resin pillow filler has good water absorption, the biodegradable resin pillow filler absorbs moisture such as sweat when using the pillow of the present invention, Therefore, the feeling of use is improved without stickiness.

The absorbed moisture is released if the pillow is dried, so that when the pillow is used again, it exhibits excellent hygroscopicity.

[0009] In the pillow according to the present invention, it is preferable that the filling for the pillow is cylindrical. In the case of a pillow filler having such a shape, mites and the like are difficult to settle, unlike cotton and the like.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a pillow and a pillow filler according to the present invention will be specifically described with reference to the drawings showing examples, but the present invention is not limited to the examples. However, the present invention can be appropriately modified and implemented within a range that can be adapted to the gist of the preceding and following descriptions, and all of them are included in the technical scope of the present invention.

FIG. 1 is a perspective view showing the pillow filler made of the biodegradable resin, and FIG. 2 is a partially cutaway perspective view showing an embodiment of the pillow according to the present invention.

As shown in FIG. 1, the biodegradable resin pillow filler 10 has a cylindrical shape having a cavity 11 therein.
The outer surface 12 has a high roughness and is rough.

As shown in FIG. 2, the pillow 20 of this embodiment is
Is a biodegradable resin pillow filler 1 inside a cloth bag 21.
It is packed with many zeros. The reason is that cotton is preferable as the material of the cloth bag 21 because cotton has good hygroscopicity.

The above-mentioned filler for pillows made of biodegradable resin can be obtained by the production method described in Japanese Patent Application No. 10-37544 filed by the present inventors, that is, for example, a water content of 13% by weight. % Corn starch at 70 ° C for 24 hours
After heating with hot air for 5 hours to reduce the water content to 5% by weight, cellulose acetate, CaCO ₃ and dimethyl phthalate (plasticizer) are added to the corn starch and mixed, and then put into an extruder and extruded. Thus, a small cylindrical biodegradable resin pillow filler 10 is obtained. Or after the water content of 13% by weight of corn starch and 36 hours hot air heated at 70 ° C. reduced to water content 3 wt%, the cellulose acetate to the said cornstarch Similarly, CaCO ₃ and dimethyl phthalate (plasticizer) Are added and mixed, and extruded by an extruder to obtain a small cylindrical biodegradable resin pillow filler 10.

While the conventional polyethylene macaroni type pillow filler has a water absorption of 0.015% (measurement method: JIS K 7209), the biodegradable resin pillow filler 10 of the present invention has a water absorption of 0.015% (measurement method: JIS K 7209).
Has a water absorption of 4 to 5% (measurement method: JIS K 7209) (average 4.
Thus, the pillow 20 using the biodegradable resin pillow filler 10 absorbs sweat well and provides a comfortable feeling of use.

The outer surface of the conventional polyethylene macaroni-type pillow filler is generally smooth and therefore slippery.
Therefore, when the head is placed on the pillow, the individual pillows for the macaroni type pillow move due to the weight of the head, and the shape of the original pillow collapses, and a predetermined height cannot be secured, and the height is lowered. There's a problem. However, since the biodegradable resin pillow filler 10 used for the pillow 20 of the present embodiment has a high surface roughness, the frictional resistance between the pillow fillers is increased, and the individual biodegradable resin pillow fillers are increased. 10 is less slippery, so that the biodegradable resin pillow filler 10 does not move much. Therefore, the initial pillow shape can be maintained for a relatively long time, and the possibility that the mounting portion of the head becomes extremely low is reduced.

Furthermore, since the biodegradable resin pillow filler 10 is unlikely to generate static electricity, it does not absorb much dust and can maintain cleanliness for a long period of time.

In addition, the biodegradable resin pillow filler 10
Since it emits no harmful gas when burned, it can be incinerated, and because it can be decomposed by microorganisms in nature, it can also be landfilled in soil.

The biodegradable resin pillow filler 10 may contain a deodorant (eg, hinokitiol).

[0020]

As described above, the pillow and the pillow filler according to the present invention have excellent hygroscopicity (water absorbency), so that they absorb sweat and the like, and provide a comfortable feeling of use. Furthermore, since the pillow filling does not easily move, the original pillow shape is not significantly deformed even when the head is placed, and there is also an effect that a predetermined height can be secured.
