DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a textile product for bedding. As a textile product for bedding, it always generates strong negative ions, and has excellent antibacterial properties, deodorant properties, and excellent heat retention.

[0002]

2. Description of the Related Art In recent years, environmental problems such as global warming and acid rain have been widely taken up. In particular, it is said that, in daily life in urban areas, positive ions in the air due to exhaust gas and the like increase and negative ions decrease, which has an adverse effect on our bodies and the environment. It is said that when positive ions increase compared to negative ions, oxidative decay, abnormalities in the body, and aging progress, and our bodies, environment, plants, and water are now weakly acidic. Therefore, the negative ion effect is to create the negative ions that are missing and reduce them to neutrality. Negative ions occur abundantly in forests, waterholes, shorelines, etc., which are naturally rich in water,
It has a healing effect that calms the hearts of people.

[0003] Tourmaline ore has been found to emit such negative ions. This tourmaline, also called tourmaline, is a substance that has a permanent spontaneous electric polarization, but generates negative ions due to external stress. For example, Japanese Patent Publication No. 6-104926 proposes an electret fiber in which finely divided tourmaline is fixed or contained in an organic fiber.

[0004] However, originally, the negative ions generated by the tourmaline itself in a stationary state are weak, and there is no material that generates a strong negative ion whenever necessary.

[0005]

SUMMARY OF THE INVENTION In view of the background of the prior art, it is an object of the present invention to provide a textile product for bedding which generates a strong negative ion whenever necessary.

[0006]

The present invention employs the following means to solve the above-mentioned problems. That is, the fiber product for bedding of the present invention has a distance from the fiber surface of 5 c under a condition where the repetitive stress accompanied by at least one of friction and vibration is 10 Pa or more.
m, the number of negatively charged molecules in the air is 300 / c
c or more.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS It is clear that negative ions have a healing effect on humans in forests, waterholes, shorelines, etc. which are naturally rich in water. Therefore, the present invention has made an intensive study on whether such a healing effect can be achieved by a normal fiber structure.

[0008] In a stationary state of a normal fiber product that generates negative ions, the generation of negative ions is very weak. As a result of intensive studies on how to increase the generation of negative ions, the present inventor has found that in applications where there is a repetitive stress accompanied by at least one of friction and vibration,
It has been found that a strong negative ion can always be generated.

In order to always generate strong negative ions within 5 cm in the vicinity of the fiber, it is desirable that stronger friction and vibration accompany the fiber.
Depending on the surface roughness of the textile, the dynamic friction
It is preferably Pa or more, more preferably 15 Pa or more. Although the content of the friction is not particularly limited, for example, friction between the skin and the fibrous structure is also preferable, and a fibrous structure and a fibrous structure, such as a futon side material and a futon filling, are also preferable. Further, the friction between warp yarns and the friction between cottons in one fiber structure is also preferable, and the friction between single yarns in one yarn is also preferable. In particular, in the case of a fibrous structure made of a single yarn having an irregular cross section having a large surface roughness in order to increase the coefficient of static friction, friction between the fibrous structures gives a favorable result for generating negative ions.

Further, the vibration may be in either the high frequency range or the low frequency range, but the amplitude is preferably 0.5 mm or more and 0.2 Hz or more, more preferably the amplitude is 1 mm or more and the frequency is 1 Hz or more.

In the present invention, a repetitive stress is indispensable in order to exert a sufficient effect, and the value is preferably 10 Pa or more, more preferably 15 Pa or more. It has been found that as a use satisfying such a condition, there are bedding textile products such as futon side lining, futon wadding, blanket, blanket side lining, sheets, and pillow cover. Strong negative ions are constantly generated from bedding textiles due to friction between the human body and bedding at bedtime and friction and vibration caused by involuntary movements such as respiration and blood circulation. In particular, textile products with a large surface area, such as cotton wool for blankets and blankets, generate microscopic friction and vibration over a wide range, generating strong negative ions. Therefore, by implementing the present invention, a healing effect due to generation of negative ions can be definitely expected.

Further, the present invention provides antibacterial properties, which are required properties not only for negative ion generation but also for textile products for bedding.
Since it has both deodorant and heat retaining effects, it is possible to provide a comfortable and comfortable space for humans in terms of function.

The negatively charged molecule of the present invention indicates a broadly-defined negative ion. Negative ions in a narrow sense refer to molecules in the air that are negatively charged, but in the present invention, static electricity generated by friction and vibration is charged to highly volatile molecules, and as a result, is released into the air In some cases, these are included as negative ions in a broad sense.

In the present invention, such a negative ion is defined as one that is measured by the following method. <Measurement of negative ions> Apparatus: AIR ION COUNTER (made in USA) Measurement conditions: room temperature 20 ± 1 ° C, humidity 50 ± 3%, room size 3 × 5 × 5m Measurement time 5 minutes, suction volume 60L / min Sample size 20 × 20 cm Evaluation content: Measurement time: 5 minutes The average generation amount of negative ions and positive ions is measured.

The measurement procedure is as follows: (1) Weave a 20 × 20 cm cloth to be evaluated three times,
Make it 2.5cm x 20cm.

(2) Hold the portion 7 cm from both ends of the sample after (1) with both hands and move it within 10 cm from the measurement section of the AIRION COUNTER.

(3) Using both hands, turn the bicycle around the center of the sample as if the foot is stepping on the bicycle pedal.

(4) The above measurement procedures (1) to (3) are repeated three times, and the average value is defined as the amount of generated ions. The unit is unit / CC.

(5) Under the conditions of (3), the friction is 500 Pa or more in dynamic friction and the repetitive stress is 500 Pa or more due to the surface roughness of the fabric.

Examples of the powder generating such negative ions include bamboo dry powder, hinoki dry powder, and paulownia dry powder. This is because it has been found that the fragrance component contained in bamboo, hinoki and paulownia tends to be very negatively polarized. These are contained or adhered to the fiber by various processes, and volatilize by applying friction, vibration, or heat, thereby releasing negative ions. Also,
Many woods, not only bamboo, cypress and paulownia, have already been confirmed to generate negative ions when carbonized, but wood before carbonization is a natural material that has excellent hygroscopicity, antibacterial properties and deodorant properties Since it is a functional substance, and it is important to generate negative ions, it is very problematic that these excellent functions are reduced and lost due to carbonization. Therefore, in order to obtain natural functional substances that also generate negative ions while having excellent moisture absorption, antibacterial properties, and deodorant properties, bamboo and wood, which have volatile components that are easily negatively polarized, among others In particular, it has been found that crushing of bamboo, cypress and paulownia after freeze-drying is sufficient.

As the powder that generates negative ions, a dry powder of tea leaves is preferably used. This is because it has been found that the aroma component of green tea is very easily polarized negatively. These are contained or adhered to the fiber by various processes, and volatilized by applying friction, vibration, or heat, and as a result, release negative ions. Here, the same effect can be expected with any substance if a volatile component that is easily polarized negatively is used.However, using the scent of green tea that Japanese people have been drinking since ancient times can also have a mental effect. More preferred.

As a powder for generating negative ions, tourmaline powder is preferably used. This is to generate negative ions when a stress is applied from the outside. In the present invention, tourmaline ore called so-called tourmaline is preferably used.

As the powder generating negative ions, an inorganic porous material having pores with an average pore radius of 20 nm or more and a specific surface area of 20 m ² / g or more can be preferably used. As the pore radius increases, the voids increase and the specific surface area generally increases. Due to external stress, distortion occurs in the member containing the negative ion generating substance of the inorganic porous material, causing polarization in the crystal structure and generating negative ions. It can release negative ions. In addition, when the pore radius and the specific surface area are large, the contact area with gas (air) or liquid (water) increases and the activity increases. Therefore, those having pores with an average pore radius of 20 nm or more and a specific surface area of 20 m ² / g or more are preferably used. The average pore radius is used to smoothly pass gases such as air and liquids such as water in inorganic materials, and to enhance activities such as generation of negative ions, emission of far-infrared rays, and adsorption of odor components. Is preferably 20 nm or more, more preferably 30 nm or more, from the viewpoint that larger is better. The specific surface area is made that there is a gap larger, from the viewpoint of contact with the same gaseous or liquid and pore radius is increased, 20 m ² / g
Or more, preferably 30 m ² / g or more. Here, the average pore radius is measured according to a mercury intrusion method pore distribution measurement (PD) method using a Carlo Elva 2200 type apparatus. The specific surface area is measured according to a specific surface area measurement method using a device of QUANTA SORB OS-8 manufactured by QUANTA CHROME.

The inorganic porous material is composed of a very large number of elements, but Mg, Fe, Li, Al, Na, B, Si,

For example, inorganic substances such as porous mud, clay, diatomaceous earth, bamboo charcoal, charcoal, coconut shell activated carbon, coal-based activated carbon, zeolite, and pearlite are preferably used, but are not limited thereto. Above all, natural inorganic porous mud is preferably used, and various nekton (shells, fish), plankton (microorganisms), and algae in the sea and lakes were buried and deposited mainly due to crustal deformation several thousand years ago. Presumed mud distributed in a specific area is preferably used. For example, it is included in the fault in the mountains of Tanagura-cho, Higashishirakawa-gun, Fukushima Prefecture and Shigaraki-cho, Koka-gun, Shiga Prefecture. These mud often contain silicon dioxide and aluminum oxide. In particular, when silicon dioxide contains at least 40% by weight and aluminum oxide at least 7% by weight, it tends to have a porous structure as a natural product. This is particularly preferred. Natural porous mud is 3

It is also possible to artificially obtain an inorganic porous material. At this time, a composite oxide containing 15% by weight or more of silicon dioxide and 85% by weight or more of at least one of zinc oxide, zirconium oxide, and anatase-type titanium oxide is preferably Nippon Shokubai Co., Ltd. ) -SX1) can be preferably used.

In the present invention, the powders that generate negative ions include dry bamboo powder, paulownia dry powder, dry tea leaf powder, tourmaline ore powder, and fine pores having an average pore radius of 20 nm or more; In addition, at least one of five kinds of inorganic porous substance powders having a specific surface area of 20 m ² / g or more can be used, and these can be used alone or in combination of two or more kinds. It is preferable to use a mixture of a plurality of types, because a synergistic effect of the negative ions generated by the inorganic powder and the aromatic negative ions generated by the organic powder and antibacterial properties can be expected.

In the present invention, the method of applying the powder that emits negative ions includes a method of applying the powder to the fabric by post-processing, a method of kneading the raw yarn and spinning, and a method of applying the powder in a heat treatment step. The first method can be applied to fibers of any material, but the latter two methods are limited to synthetic fibers.

When applied to textiles by post-processing, it is preferable to use a binder to fix the powder that emits negative ions to the fibers. The binder used in the present invention is not particularly limited, but an acrylic resin, a polyurethane resin, a silicone resin, a fluorine resin, a melamine resin, a glyoxal resin, or the like may be used in consideration of the texture and washing durability.

More specifically, an aqueous dispersion of a powder emitting negative ions and an aqueous binder solution are mixed to prepare a working liquid.
After impregnating the processing liquid with the fiber product, it is squeezed to a certain amount with a mangle roll or the like, and then subjected to a dry curing step or a steam-curing step, and the powder generating negative ions is fixed to the fiber product by a binder. For example, heat treatment with steam is also preferably used. The fabric to which the powder that generates negative ions is attached

The fiber emits negative ions with excellent durability. This heating steam treatment is preferably used for cellulosic fibers.

Also, powder which generates negative ions can be provided by applying a processing liquid to textiles. For example, the working fluid is adjusted to an appropriate viscosity, and is applied by a knife coater, a gravure roll coater, printing, or the like, and then heated to 200 ° C.
It is advisable to fix at the following temperature. At this time, in order to improve the surface roughness of the fabric surface and increase the coefficient of static friction, it is a minus to print the print pattern at the time of printing and make a belt-like print at an interval of 1 times or more the width of the print pattern. It is preferable in terms of ion generation conditions.

In the present invention, as a method of applying a powder which generates negative ions by kneading to the fiber, a method of mixing the powder into a fiber solution before spinning is preferably used.

In the present invention, the method of applying a powder that generates negative ions to the fiber through the heat treatment step is a method of applying the powder by a heat treatment in a step of stretching the spun synthetic fiber. After spinning for acrylic fiber,
The thread is applied in a step of dipping in a chemical bath. Specifically, a powder that generates negative ions is mixed in a chemical bath to form a dispersion liquid, attached to fibers, and then fixed by a heating step. In the case of polyester-based fibers and nylon-based fibers, after spinning, an oil agent is applied and heat drawing is performed. A powder that generates negative ions is added to the oil agent to form a dispersion, which is applied to the fibers.

When a powder that generates negative ions is applied in an undrawn state in which the fiber has not yet been crystallized, the powder easily enters the amorphous portion of the fiber. Therefore, after the fiber is drawn or densified by a heat treatment step, Also, a part of the powder remains buried in the fiber, and the fiber emits negative ions with excellent durability.

When the above-mentioned powder generating anions is contained in an amount of 0.1% or more and less than 50% with respect to the weight of the fiber, the fiber product for bedding using the same can provide peace of mind to people.

As the form of the powder that generates negative ions, a particulate form is preferably used. This is because the particles are excellent in dispersibility in a solvent such as water or an oil agent. Further, when kneaded into the original yarn, the yarn production is stable, and also when applied to the fiber through a heat treatment step, the particle-like form allows the negative ion generating powder to easily enter the amorphous portion.

The average particle diameter of the powder that generates negative ions is 0.01 to 100 when a dispersion is prepared.
μm is preferred. Further, an inorganic or organic dispersant as a dispersion stabilizer is added to the powder in an amount of 0.05 to 2
It is preferable to use 0% by weight. Further, in order to make the powder into fine particles, techniques such as dry pulverization, wet pulverization, and freeze pulverization can be used.

When kneading a powder that generates negative ions into a single yarn of synthetic fiber, it is preferable that the particle diameter is 0.01 μm or more and 10 μm because the yarn production is stable.

The fiber product for bedding using the fibers emitting negative ions according to the present invention is composed of at least one selected from synthetic fibers and natural fibers. Examples of such synthetic fibers include acrylic fibers such as acrylic and modacrylic, polyester fibers, nylon fibers such as nylon 6 and nylon 66, polyolefin fibers such as polyethylene and polypropylene, polyamide fibers, polyvinyl chloride fibers, and vinylon.

The fiber product for bedding of the present invention may use these synthetic fibers or natural fibers alone, or may be formed by blending or blending them. In addition to fabrics such as woven fabrics, knitted fabrics and non-woven fabrics, it is possible to use any products including fibers such as strips, cords, and yarns, regardless of their structures and shapes.

Further, in the present invention, it is preferable that the required properties of the bedding textile are additionally provided to make the textile more suitable. The required properties include antibacterial properties, deodorant properties, heat retention properties, and the like.

For imparting antibacterial properties, inorganic antibacterial agents and pyridine or quaternary ammonium salt-based organic antibacterial agents can be used. Among them, zinc 2-pyridinethiol-1-oxide, 2-chloro-4-trichloromethyl-6- (2-furylmethoxy) pyridine, 2-chloro-6-trichloromethylpyridine, sodium 2-pyridinethiol-1-oxide , 1,4- (1-diiodomethylsulfonyl) benzene, 10,10'-oxybisphenoxyarsine, methyl 6- (2-thiophenecarbonyl) -1H-2-benzimidazolecarbamate, 5-chloro-2- Methyl-4-isothiazolin-3-one and the like are preferably used.

For imparting deodorant properties, any of a physical adsorption system, a neutralization system, an oxidative decomposition system, and a masking system can be employed. In the physical adsorption system, activated carbon, alumina, zeolite, and the like can be used. As the neutralizing system, a metal oxide such as a zinc compound or a copper compound for an acidic odor and a polymer compound containing a carboxylic acid for a basic odor can be used. In addition, an excellent deodorizing effect can be expected by combining an inorganic porous material with a masking effect of hinoki, paulownia, green tea and the like. For example, if an oxidative decomposition type photocatalyst having a specific surface area of 100 to 300 m ² / g and an average primary particle diameter of 1 to 20 nm is used,
In addition to imparting deodorant properties, it also has a synergistic effect of generating negative ions. Oxidation-decomposition type photocatalyst is not less than 0.05% by weight 30
It is preferable to adhere by weight%.

For imparting heat retention, a mechanism such as a moisture absorption / heat retention system or a heat insulation system can be considered. The concept of insulation and heat retention is widely used in bedding, and examples thereof include a futon using a batting rich in an air layer and a blanket in which an air layer is taken in by raising the hair. By giving these insulating materials moisture absorption and heat retention, warmer bedding can be created.

The moisture absorption and heat retention can be imparted by adhering a polymer compound having heat absorption and heat generation to the surface of the fiber that emits negative ions. For example, vinyl carboxylic acid and / or vinyl sulfonic acid (hereinafter, referred to as “monomer A”) is polymerized with a divinyl monomer represented by the following general formulas [I], [II] (hereinafter, referred to as “monomer B”). A method of adhering to the fiber surface is employed.
