The inventors of the present invention have made various studies in order to provide a bedding foam capable of exerting a hypnotic effect. As a result, an extract extracted from onion is effective as a component that exhibits arousal for a long period of time, and the onion extracted component can be dispersed and stably contained in a foam matrix. The present invention has been completed. Hereinafter, the operational effects and the like of the present invention will be described in detail.

  The foam for bedding according to the present invention is formed as a pillow or a mattress, and is obtained by dispersing extract components collected from onions in a foam matrix having a large number of bubbles and forming a foam. First, onion extract will be described.

  Various onions can be used, such as yellow onions, red onions, and white onions. The onion to be used is preferably a fresh one whose time since collection is not so much. The onion removes the attached soil and the like, peels off the outer skin, and is a knife such as a knife or knife. For example, the onion is about 0.5 to 5.0 mm, preferably about 1.5 to 3.0 mm. Chop into small pieces. Next, a liquid onion extract can be obtained by putting a small piece of this onion into a press and pressurizing it. Thus, when the onion is finely chopped to a size of 0.5 to 5.0 mm, and the extracted components are collected by squeezing the onion, the onion extract can be efficiently collected and mixing of impurities and the like can be suppressed. It is preferable in that it can be performed.

  In addition, the onion extract can also be extracted by squeezing the crushed pieces obtained by chopping the onion, which has been cut into large squares, in an electric mixer. Alternatively, when the whole peeled onion is put into a squeezing device driven by an electric motor such as a motor and the extracted components are squeezed, the work can be performed efficiently.

  The onion extract obtained by squeezing in this way can be used in a liquid state. However, it can also be used by processing into a dry powder form by evaporating water using a dryer or an electromagnetic heater. Use of the powdery extracted component thus obtained is preferable in that it can disperse more uniformly in the matrix of the foam, so that the arousal effect can be further stabilized. Moreover, handling property can also be improved by making it powdery rather than liquid.

  Furthermore, the obtained onion extract can be used by being supported on an organic or inorganic porous fine powder. As these porous fine powders, porous cellulose beads, wood powder and the like can be used in the organic system. Inorganic materials include porous minerals such as diatomaceous earth, zeolite, and sepiolite, as well as inorganic porous fine powders such as silica gel, allophane, imogolite, and charcoal. When inorganic materials are used, heat resistance and chemical resistance From the viewpoint of excellent stability. In this way, when the extract components collected from onions are supported in a porous fine powder and dispersed in the foam matrix, the onion extract components are contained in a more stable state in the foam. Can do. Therefore, the onion extract component is stably and volatilized, which is preferable in that it can exhibit an excellent sleeping effect.

  The onion extract component obtained as described above is dispersed and contained in the foam matrix to form a bedding foam. As the foam, for example, a flexible polyurethane foam can be used. The flexible polyurethane foam is obtained by a polymerization reaction by mixing a foam raw material containing a polyol and an organic isocyanate in a mold together with a foaming agent, a foam stabilizer, and a catalyst. In addition to the flexible polyurethane foam, a rigid polyurethane foam or a semi-rigid polyurethane foam can also be used as the foam.

  As the polyol component, known polyols usually used for molding of urethane foam can be used. As such polyols, for example, polyether polyols, polyester polyols, polyether ester polyols, polymer polyols and the like are used, and polyether polyols are particularly important. A polyol obtained by further modifying a polyether polyol can also be used.

  The foam used for bedding is preferably a low-foaming urethane foam in order to disperse body pressure and obtain good sleeping comfort. In such a case, a known polyol which is usually used for molding a low foaming urethane foam can be used. As this kind of polyol, for example, at least one selected from the group consisting of polyoxyalkylene polyol, vinyl polymer-containing polyoxyalkylene polyol, polyester polyol, and polyoxyalkylene polyester block copolymer polyol is preferably used. Can do.

  As a component of the organic isocyanate, a known organic isocyanate which is usually used for molding a urethane foam can be used. Examples of such organic isocyanates include 2,4- or / and 2,6-tolylene diisocyanate, diphenylmethane diisocyanate or derivatives thereof, 1,5-naphthalene diisocyanate, tolidine diisocyanate, isophorone diisocyanate, p-phenylene diisocyanate, xylylene. Diisocyanate or its hydrogenated product, lysine diisocyanate, tetramethylxylylene diisocyanate, lysine ester triisocyanate, 1,6,11-undecane triisocyanate, 1,3,6-hexamethylene triisocyanate, bicycloheptane triisocyanate, etc. are used. It is done. These modified polyisocyanates and prepolymers can also be used in the same manner.

  As said foaming agent, the well-known foaming agent normally used for shaping | molding of a urethane foam can be used. Examples of such blowing agents include water and / or halogen-substituted aliphatic hydrocarbon blowing agents such as trichlorofluoromethane, dichlorodifluoromethane, trichloroethane, trichloroethylene, tetrachloroethylene, methylene chloride, trichlorotrifluoroethane, dibromotetra Examples include fluoroethane and carbon tetrachloride. These foaming agents may be used in combination of two or more, but in the present invention, it is preferable to use water alone. Furthermore, in the case where the extract component obtained by squeezing onion is not dried and is blended in a liquid state, without using water as a foaming agent separately, or in addition to water added as a foaming agent, The water in the extracted component can also be used as a foaming agent.

  As the foam stabilizer, a silicone-based surfactant is preferably used, and a nonionic or ionic surfactant may be used in some cases. As the catalyst, a tertiary amine such as triethylenediamine, an organic tin compound such as stannous octoate, or the like is used. In the reaction, in addition to these foaming agent, foam stabilizer, and catalyst, a colorant and an antioxidant can be added and blended as necessary.

  The onion extraction component is blended in a foam raw material containing the polyol, organic isocyanate, and foaming agent, foam stabilizer, catalyst, etc., and mixed in a mold to form a foamed flexible polyurethane foam matrix. It is dispersed and contained. Therefore, because the required amount of onion extract is distributed throughout the foam, the onion extract component is constantly volatilized and diffused from the entire surface of the foam. So you can go to sleep quickly. Moreover, it is possible to sleep well in a deep sleep until sufficient sleep time elapses.

  The method for producing a foam for bedding according to the present invention is a production method characterized in that, in the production of a foam for bedding using the flexible urethane foam, the onion extract component is blended in a liquid state, and then this production is performed. The process will be described.

  In this production method, the liquid extract component collected by squeezing onion as described above is used as it is without being dried. The foam raw material containing the polyol and the organic isocyanate is mixed with the liquid extraction component that is squeezed out of the onion and contains the onion extract in water. Specifically, the foam raw material is prepared by blending, for example, 20.0 to 50.0 parts by weight, preferably 30.0 to 40.0 parts by weight of organic isocyanate with respect to 100 parts by weight of polyol. Furthermore, the onion extract component is similarly added to, for example, about 0.1 to 10.0 parts by weight, preferably 1.0 to 5.0 parts by weight, and mixed well with sufficient stirring. If the amount is less than 0.1 parts by weight, the hypnotic effect is insufficient. Conversely, if the amount exceeds 10.0 parts by weight, the extract becomes excessive, which may cause discomfort for the sleeping sleeper.

  By mixing and stirring these in a mold, the water in the onion extract component functions as a foaming agent as the polymerization reaction proceeds, and a porous soft polyfoam can be formed. In this way, a liquid extraction component obtained by squeezing onion is added to the foam raw material, and water contained in this liquid extraction component is used as a foaming agent to advance the polymerization reaction to make a porous soft polyurethane. When the foam is molded, it is not necessary to separately add a foaming agent, which is preferable in that stable urethane foam molding can be obtained.

  As described above, a foam stabilizer, a catalyst, a colorant, an antioxidant, etc. are appropriately added to the foam raw material, and when the amount of water contained in the extraction component is insufficient, An appropriate amount of water can also be added.

The foam for bedding of the present invention can also employ a production method in which an extract of onion is dispersed and contained by impregnating and absorbing an extraction component collected from onion into a foam-formed foam matrix having open cells. In the method for manufacturing foam for bedding, the case where a flexible urethane foam is used will be described as an example. First, a foam forming process for forming a matrix of foam having open cells is performed. In this step, the same foam foam raw material containing polyol, organic isocyanate, foaming agent, foam stabilizer, and catalyst as above is mixed in a mold to produce a flexible polyurethane foam. The density of the obtained flexible polyurethane foam is, for example, about 10 to 100 kg / cm ³ .

  In the subsequent impregnation treatment step, the liquid extraction component collected from the onion is absorbed into the foam matrix through the communicating bubbles. At this time, the foam molded in the foam molding process is pressurized and compressed to release part of the air in the communicating bubbles. By releasing the pressure while immersing the foam in this state in the liquid component collected from the onion, the onion extract component can be sucked into the foam matrix and dispersed. By repeating this operation several times, the entire foam can be impregnated with the onion extract. In addition to this method, the onion extraction component can be absorbed into the foam by capillarity of the foam open bubbles.

  In this way, when the foam for bedding is manufactured by the foam molding process for molding the foam matrix and the impregnation treatment process for absorbing and dispersing the onion extract component into the matrix through the open cells, it is easy because it is close to the surface of the foam. Since a lot of onion extract components are dispersed in the area where volatilization occurs, the amount of volatilization increases and the arousal effect can be enhanced. In addition, by impregnating various types of foams molded by the foam molding process with an onion extract component of a type or concentration according to requirements in the impregnation process, a foam for bedding that can respond precisely to various needs. Easy to manufacture.

  The foam for bedding of the present invention can use latex foam in addition to the flexible urethane foam. In this bedding foam, a latex raw material containing at least one selected from natural or synthetic latex rubber such as NBR latex, SBR latex, chloroprene rubber (CR) or NR latex rubber, an organic peroxide, zinc A cross-linking agent such as flower, each required additive, and the extracted components collected from the onion are mixed and kneaded in a required amount in a mixing device, and the kneaded product is poured into a closed foaming mold and heated. By doing so, the latex raw material can be cross-linked to form a latex foam having a required shape. In the latex foam matrix thus obtained, the onion extract components blended in the latex raw material are dispersed and uniformly dispersed throughout the foam. Therefore, latex bedding having a high repulsive force and capable of realizing a good sleeping posture and excellent body pressure dispersion is preferable in that the onion extract component can be dispersed and contained.

  Hereinafter, the present invention will be described in more detail by way of examples. This embodiment is not of a nature that limits the present invention, and can be implemented with appropriate modifications within a range that can meet the gist of the following description, and they are all included in the technical scope of the present invention. .

  The foam for bedding is 40kg PPG (polypropylene glycol) as polyol, 24kg TDI (Tolylene Diisocyanate) as organic isocyanate, 2.5kg dichloromethane (methylene chloride) as solvent, 1.8kg water as foaming agent, foam stabilizer As a catalyst, 500 g of silicone oil (L580), 70 g of amine (A-33) and 50 g of tin (D-19) as catalysts, and liquid extraction obtained by pressing the onion cut into about 2.0 mm Each component was blended in an amount of 1.6 kg and injected into a mold for pillow molding to obtain a polymerization reaction in the mold.

  Using the pillows of the bedding foam obtained, 10 men and women aged 10 to 70, who were randomly selected, tested the speed of falling asleep and the sense of awakening. And I was able to experience the comfort of waking up. We also tested the improvement of sleep onset by five men and women who usually complain of insomnia. As a result, a remarkable improvement effect was seen in three men and four women.
