JP5230021B2 - Laminate for bedding - Google Patents

Description

  The present invention relates to a laminate having high heat retention suitable for bedding such as a comforter, a mattress, a bed pad, a quilting ket, a shuffling, and a pillow, and a bedding using the laminate.

  Conventionally, bedding for winter, especially futons, has been devised to increase heat retention so that body temperature is not easily lost while sleeping. For example, by using a lot of padding cotton to make it bulky, using feathers or hollow synthetic fibers, increasing the air layer, improving heat retention, or embedding heating wires in bedding and heating with electricity to warm The device such as an electric blanket is made. However, if these futons are not warmed in advance with an electric blanket etc., the futons feel very cold when they enter the futon, and the body temperature is taken away by the futons, and it must be put up with cold until the futons warm up. There wasn't.

  As a means for improving the heat retaining property, there is an emergency sheet carried for example in winter mountain climbing. This is a film in which an infrared reflecting metal is vapor-deposited on a film, and the energy of the body is not released as much as possible by reflecting the infrared ray emitted from the body and returning it to the body. However, since this metal vapor-deposited sheet is a film, the texture is hard and the breathability is not good, so the comfort is very poor. In addition, the present inventors tried using the emergency sheet on the comforter, but in the indoor atmosphere of about 5 to 15 ° C., the futon has a thickness, so the heat insulation of the comforter itself is high and the emergency sheet is kept warm. It turned out that the effect is hardly felt.

  On the other hand, as a conventional technique related to a bedding using a metal coating, a futon is proposed in which a base material in which a metal or a metal oxide is adhered to the surface by a sputtering method is mounted inside the futon ( The metal used for these futons is a far-infrared metal, and the effect of absorbing and reflecting the heat rays emitted from the body cannot be expected. Actually, these futons take time to warm around the body because the material itself is warmed and then warmed by infrared radiation emitted from the material.

  Moreover, although the non-woven fabric for batting used as a batting of clothing and a futon, the non-woven fabric for batting characterized by being coat | covered with the antibacterial metal film and the corrosion-resistant metal film is proposed (refer patent document 3). This nonwoven fabric is not intended to improve heat retention or to warm quickly.

  The present invention was devised in view of the above-described conventional state of the art, and the purpose of the present invention is to comfortably feel warm immediately without taking time to feel warm when entering a futon in a cold atmosphere. An object of the present invention is to provide a laminate for bedding and a bedding using the same.

  As a result of diligent research to achieve the above-mentioned object, the inventors of the present invention have used aluminum that strongly reflects heat rays to warm the body periphery quickly after going to bed. Covering the place, further shortening the distance from the aluminum-coated surface to the skin side surface of the side as much as possible, and making the structure that the air inside the futon and the surroundings of the body is difficult to be exchanged through the side, Furthermore, it discovered that the said objective can be achieved by raising the contact temperature feeling of the ground which contacts a skin directly, and suppressing the body temperature fall by heat conduction from a body, and came to completion of this invention.

That is, the present invention has the following configurations (1) to ( 6 ).
( 1 ) A laminated body for bedding in which a front side and a skin side are joined to form a bag and filled with stuffed cotton, and an inner bag is provided between the skin side and the stuffed cotton. The laminated body for bedding characterized in that either the side surface side surface or the filling cotton side surface of the inner bag is covered with aluminum.
( 2 ) The laminated body for bedding according to ( 1 ), characterized in that an inner bag is provided between the front side land and the padding cotton.
( 3 ) The laminate for bedding according to (1) or (2) , wherein the aluminum coating thickness is 10 to 300 nm.
( 4 ) The material from the skin side surface to the aluminum coated surface closest to the skin side has a thickness of 0.02 to 0.6 mm, and the air permeability of 0.5 to 2.0 cc / cm ² · s. The laminate for bedding according to any one of (1) to ( 3 ), characterized by comprising:
( 5 ) The skin side side is made of hydrophobic fibers containing 40% by weight or more of ultrafine fibers of 0.01 to 0.5 dpf, has a thickness of 0.05 to 0.3 mm, and a basis weight of 30 to 150 g / m ² . The laminate for bedding according to any one of (1) to ( 4 ), comprising:
( 6 ) A bedding comprising the laminate for bedding according to any one of (1) to ( 5 ), wherein the padding has a thickness of 2 to 20 cm.

  Since the laminated body for bedding of the present invention is provided with a coating of aluminum with high heat ray reflectivity in a specific place close to the skin side, it eases chills when entering the futon, Can warm up quickly. Therefore, the shock caused by the cold bedding in winter can be relieved, and the comfort at the time of going to bed can be increased, so that it is possible to sleep comfortably.

  Hereinafter, the laminated body for bedding of the present invention will be specifically described.

  The laminated body for bedding according to the present invention is obtained by connecting a front side and a skin side to form a bag and filling with cotton. Furthermore, the laminated body of this invention can provide an inner bag between the front side and the filling cotton, or between the skin side and the filling cotton, or both. The side cloth and the inner bag are cloths that wrap or cover padding for bedding such as a futon. The side ground is formed into a bag shape by connecting a front side portion intended to be in contact with outside air and a skin side portion intended to be in contact with human skin. For example, when the stuffed cotton is feathers, the inner bag guards the feathers so that the feathers do not blow out from the side ground. However, if the side ground itself has the function, the inner bag need not be used. . For visual understanding, schematic cross-sectional views of a laminate comprising a side fabric and padding cotton, and further using an inner bag are shown in FIGS. 1 and 2, respectively.

  The laminate of the present invention is characterized in that aluminum is coated so that the surface of the component on the skin side from the padding cotton is not brought into contact with the skin. Specifically, the surface of the stuffed cotton side of the skin side or the side of the inner bag of the skin side or the surface of the stuffed cotton side is coated with aluminum. When covering the surface of the inner bag on the skin side with aluminum, it is preferable to cover the surface on the side of the ground from the side of the filling cotton. The reason for not covering the surface of the front side and the inner bag with aluminum is to avoid that the aluminum-coated surface is too far away from the body and cannot fully exhibit the heat ray reflecting function of aluminum. In that sense, the aluminum coating is preferably provided as close to the skin as possible, but it is important not to provide the aluminum coating on the skin-side surface of the skin side. This is to prevent the chilly feeling due to the high thermal conductivity of metals from being transmitted directly to the body.

  In the laminate of the present invention, it is preferable that the material from the skin side surface to the aluminum coated surface closest to the skin side has a thickness of 0.02 to 0.6 mm. A preferable upper limit of the thickness is 0.3 mm, and more preferably 0.2 mm. The thickness is preferably as small as possible as long as the aluminum-coated surface does not come into contact with the skin. However, considering the durability of the material, the preferred lower limit is 0.05 mm. When the thickness exceeds the above range, it takes time for the heat rays reflected by the aluminum-coated surface to exert the effect of warming the body and the skin side. In addition, when the said material consists of a some fabric, the said thickness does not include the air layer between fabrics.

  The thickness of the aluminum coating of the laminate of the present invention is preferably 10 to 300 nm. More preferably, it is 20-200 nm, More preferably, it is 30-100 nm. When the thickness is thinner than the lower limit, it becomes difficult to uniformly coat the uneven fabric surface with aluminum, and durability in actual use becomes insufficient. Moreover, when thickness is thicker than the said upper limit, there are few improvement effects in terms of a heat ray reflective effect or the durability of a covering metal, and it becomes economically inefficient. In addition, phenomena such as discoloration of metal are likely to occur.

  The aluminum coating is applied to the surface of the side fabric or inner bag, but in practice after the fabric constituting the side fabric or inner bag is subjected to general scouring, bleaching, dyeing, drying, heat setting, etc. It is preferably applied in a dry state. Examples of the method for coating aluminum include a plating method, a coating method, a physical vapor deposition method, and the like, but a physical vapor deposition method that can suppress changes in the texture and air permeability of the fabric as much as possible is preferable. Physical vapor deposition methods can be broadly divided into vacuum deposition, molecular beam deposition, ion plating, ion beam deposition methods, and sputtering methods. From the surface, the vapor deposition method is preferable.

  The fabric constituting the side fabric and the inner bag used in the laminate of the present invention may be a woven fabric, a knit such as circular knitting or warp knitting, or a nonwoven fabric, but the fabric used for the lateral fabric is preferably a woven fabric or a knit fabric. is there. The fabric can be made of a thin and lightweight side fabric with excellent strength and wear, and the knit fabric can be produced with a stretch and soft texture. The fabric used for the inner bag is preferably a woven fabric or a non-woven fabric. Since the knit is rough, it is difficult to suppress the blowing of the filling cotton.

  Synthetic fibers are preferable as the material for the side fabric and the inner bag used in the laminate of the present invention, and hydrophobic fibers having a low official moisture content are particularly preferable. When the moisture content of the fiber is high, the feeling of cooling becomes strong due to the thermal conductivity of water, which is not preferable. The moisture content of the fiber is preferably 5% or less, more preferably 1% or less, and even more preferably 0.5% or less. Examples of such hydrophobic fibers include polyester fibers such as polyethylene terephthalate, polytrimethylene terephthalate, and polybutylene terephthalate, polyamide fibers such as nylon 6 and nylon 66, polyolefin fibers such as acrylic fiber, polypropylene, and polyethylene, and polyurethane fibers. And polyimide fiber. Among these, polyester fiber, polyolefin fiber, and acrylic fiber, which have particularly low hygroscopicity, are preferable. By using these fibers singly or in combination, fabrics for side fabrics and inner bags can be produced.

  The single yarn fineness of the fibers constituting the side fabric is preferably in the range of 0.01 to 5.0 dpf (decitex / filament), but in order to make it difficult to feel cold when touched, the side fabric is used. It is more preferable to use an ultrafine fiber of 0.01 to 0.5 dpf for 40% by weight or more of the constituent fibers. A more preferable single yarn fineness is 0.1 to 0.5 dpf. Examples of the method of mixing ultrafine fibers include a method of using ultrafine fibers for the warp and weft of the woven fabric, and a method of using ultrafine fibers for the skin surface of the knitted fabric.

As for the side ground of the laminate of the present invention, the thickness and basis weight of the conventional side ground can be adopted as they are, but the thickness of the side ground is preferably 0.01 to 0.9 mm, and the side ground weight is 30 to 150 g. / M ² is preferred. If the thickness or basis weight of the side ground is less than the above range, the durability is inferior, and if it exceeds the above range, the distance between the aluminum-coated surface and the skin becomes long. Moreover, the inner bag of the laminate of the present invention may adopt the thickness and basis weight of the conventional inner bag, but the thickness of the inner bag is preferably 0.01 to 0.9 mm, and the basis weight of the inner bag is 30 to 150 g. / M ² is preferred. When the thickness and basis weight of the inner bag are less than the above ranges, the durability is inferior, and when the thickness exceeds the above ranges, the distance between the aluminum-coated surface and the skin becomes long, which is not preferable.

  Moreover, when using a textile fabric for a side place, 1000-4000 are suitable for the cover factor of a textile fabric. More preferably, it is 1500-3600, More preferably, it is 1800-2600. If the cover factor is less than the above range, air permeability is high, and when the air around the body warms up, the air inside the futon and the air on the body side move through the side fabric, and the temperature rise around the body moderately Prone. Moreover, when higher than the said range, the texture of a side place becomes hard and there exists a possibility that the drape property (goodness of skin addition) of bedding may worsen. Moreover, when using a knitted fabric for a side fabric, it is good to use a woven fabric or a nonwoven fabric as an inner bag, In that case, it is preferable that the cover factor of a woven fabric is the same as the above.

In the laminated body of the present invention, the material from the skin side surface to the aluminum-coated surface closest to the skin side preferably has an air permeability of 0.5 to 2.0 cc / cm ² · s. If the air permeability exceeds the above range, air movement tends to occur, and the temperature rise around the body tends to be slow. If it is less than the above range, it is difficult for air to escape during filling of the filling cotton, and it takes time to fill.

Conventionally known materials such as polyester, feathers, and wool can be used as the material for the filling cotton used in the laminate of the present invention. Since the object of the present invention is to get warm immediately, a material having as low a thermal conductivity as possible is preferably used. For this reason, feathers containing a large amount of air layer are more suitable. The thickness of the filling cotton is preferably 2 to 20 cm, more preferably 3 cm or more, and further preferably 5 cm or more. Also, the basis weight of the packed cotton is preferably 50~3500g / ^{m 2,} more preferably from 100 to 500 g / ^{m 2.} If the thickness and basis weight of the stuffed cotton are less than the above ranges, the heat generated from the body is easily released to the outside of the futon through the futon, and the effect of immediately warming the present invention is reduced. Moreover, if it exceeds the above range, the heat retaining property is improved, but the sleeping comfort is deteriorated due to the weight of the cotton.

  In order to improve the washing durability of the aluminum coating formed on the laminate of the present invention, a protective layer is preferably formed on the coating surface. As a method for forming the protective layer, a method of forming a protective film on the entire fabric by padding the fabric with a solution of an aqueous or solvent-based resin emulsion containing a resin to be the protective layer, followed by drying and curing, or aluminum There is a method in which a protective resin layer is further laminated on the coated surface by coating or gravure roll. Examples of these protective resins include acrylic resins, urethane resins, ester resins, and polycarbonate resins. In addition, these resins are water-absorbing agents, water-repellent agents, antibacterial and deodorant agents, deodorant agents, UV-cutting agents, antistatic agents, moisturizing agents, cool feeling agents, fragrance agents, insecticide agents, You may combine with functional resins, such as a hard twist processing material, an anti-slip agent, and a sewing improvement agent. Moreover, you may add a crosslinking agent in order to further improve durability.

  In addition, before coating aluminum, it is preferable to form an adhesive layer on the fabric for the purpose of improving adhesion with aluminum and improving durability in actual use. As a method for forming the adhesive layer, a method of forming an adhesive film on the entire fabric by padding the fabric with a solution of an aqueous or solvent-based resin emulsion containing a resin to be the adhesive layer, followed by drying and curing, In addition, there is a method of forming an adhesive resin layer by coating or gravure roll. As these adhesive resins, a polymer excellent in adhesiveness between the fabric material and aluminum may be selected. As the material for the adhesive layer, for example, in the case of a fabric made of polyester, acrylic resin, ester resin with improved hydrophilicity, ester urethane resin, and the like are preferable. Moreover, in the case of the fabric comprised with nylon, a urethane resin, a polyamide resin, etc. are preferable.

  The effect of the present invention can be advantageously achieved when the infrared reflection characteristics of the aluminum-coated side land or the inner bag of the present invention are 30 ° C. or higher at a thermography temperature of 10 seconds from the start of measurement. Preferably it is 35 degreeC or more, More preferably, it is 38 degreeC or more. The temperature difference (ΔT) in the case of comparative measurement using an aluminum non-coated surface as a blank is 2 ° C. or higher, preferably 3 ° C. or higher, and more preferably 4 ° C. or higher. The actual practical upper limit temperature difference (ΔT) is 15 ° C., generally 10 ° C. If the temperature 10 seconds after the start of measurement of the aluminum-coated surface is less than the above range, or if the temperature difference from the non-aluminum-coated surface is less than the above temperature, it is difficult to obtain the effect of immediately warming the present invention.

  The laminate of the present invention can be suitably used for bedding such as comforters, mattresses, bed pads, quilting kets, shruffs, pillows, etc. In that case, it is preferable that the stuffed cotton has a thickness of 2 to 20 cm.

  Next, the effects of the present invention are specifically shown by the following examples, but the present invention is not limited thereto. In addition, about the evaluation of the characteristic value, it measured with the following method.

Thickness of the aluminum coating Gently remove the yarn from the fabric sample coated with aluminum so that it does not come apart (the warp if it is a woven fabric). With the yarn stretched, the yarn is placed like a pencil core in the middle of the resin. In this way, it was embedded with an epoxy resin for an electron microscope. The resin of the embedded sample was shaved with a knife so that the pencil was sharpened to expose the thread. This was fixed to an ultramicrotome sample holder, and a cross-sectional thin section perpendicular to the longitudinal direction of the embedded yarn was produced. Next, in the section of the aluminum-coated fiber in this section where there was no significant damage to the thin film, using a transmission electron microscope (JEOL, JEM-2010), the acceleration voltage was 200 kV, the observation magnification was 10,000 times in the bright field. I took a photo. The thickness was obtained from the obtained photograph.

Fabric basis weight, thickness, air permeability Measured according to JIS-L1096.

Fabric Cover Factor The fabric cover factor (CF) was calculated by the following equation.
CF = T × (DT) ^1/2 + W × (DW) ^1/2
In the formula, T and W indicate the warp density and weft density (lines / inch) of the woven fabric, and DT and DW indicate the warp and weft thickness (dtex) constituting the woven fabric. The warp density and the weft density were measured according to JIS-L1096.

Infrared reflection characteristics of fabric The re-radiation characteristics of the Far-Infrared Society certification rules were measured by the 45-degree parallel re-radiation method (FIG. 7), and the fabric temperature of the thermography result was used as a substitute measure of the infrared reflection characteristics. In order to prevent the influence of the temperature rise of the dough as much as possible, the measurement was performed 10 seconds after the start of the test. In addition, the measurement was performed simultaneously with the aluminum-uncoated cloth as a blank, the aluminum-coated cloth having the aluminum-coated surface facing the hot plate, and the aluminum-coated cloth and the aluminum-uncoated cloth arranged side by side. At this time, each surface temperature is set as the infrared reflection characteristic of the cloth. Further, the difference ΔT1 between the surface temperatures of the aluminum-coated cloth and the non-aluminum-coated cloth measured at the same time was expressed as an infrared reflection characteristic effect of aluminum. In order to eliminate the difference between the left and right of the measurement, the left and right of both were replaced and measured twice, and the average value of the left and right was adopted. Here, when the aluminum-coated cloth is the cloth 1 of Example 1, the non-aluminum cloth is the cloth 2. Similarly, the fabric 3 and the fabric 4 in Example 2, the fabric 5 and the fabric 6 in Example 3, and the nonwoven fabric 1 and the nonwoven fabric 2 in Example 5, respectively.

Temperature change on the skin side surface of the laminate (skin model)
Using a skin model evaluation device as shown in FIG. 9, the temperature change in the bed after going to bed is measured. The measurement conditions were as follows. The performance of warming quickly was evaluated by the temperature rise ΔT near the side surface for 1 minute after the start of measurement. It shows that it becomes warm earlier as ΔT is higher. The average value was adopted with the number of measurements n = 3.
Measurement conditions: Environment 10 ° C 50% RH
Device used: Skin model
Apparatus conditions: hot plate 37 ° C., sweating amount 0 g / m ² · h, sample-hot plate distance 1 cm

Futon Monitor Test A futon was laid in an environmental test room set at 25 ° C. and 50% RH and left for 12 hours until the temperature in the futon was stabilized. Three adult men became monitors and went to sleep for 30 minutes under the following conditions as 100% polyester long-sleeved T-shirts and 100% cotton trunks. A questionnaire was conducted on the subjective subjective evaluation of three people 1 minute and 30 minutes after the start of bedtime. In addition, body surface temperature distribution immediately after going to bed for 30 minutes was measured by a thermotracer method.
Measurement conditions: Rest 30 minutes (25 ° C 50% RH) ⇒ Sleep 30 minutes (15 ° C 50% RH)
Measuring instrument: NEC Sanei Thermotracer Subjective evaluation was the average of the evaluation values of three monitors as a 7-step SD method of very cold-3 to very warm + 3.
The thermotracer temperature was obtained by reading the temperature at the middle of the thumb as the end of the body, and taking the average value of the four of the thumb of the hand and the first finger of the foot. The difference between the value measured with the futon using the aluminum-coated fabric and the value measured with the futon using the non-aluminum coated fabric was expressed as ΔT2.
