Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fabric for producing negative ions and a method for producing the same. More specifically, a cloth that can be used for clothing that contributes to health promotion of the human body, personal belongings made of fiber, bedding and building materials,
The present invention relates to a processed fabric which is effective in generating negative ions, is soft and has a good touch, and has excellent washing resistance, and a method for producing the same.

[0002]

2. Description of the Related Art It is known that when energy such as electric discharge, strong light, lines of magnetic force, radiation, heat radiation, and electromagnetic waves is radiated into the air, gas ions are generated around the energy. Gas ions include positive ions and negative ions. Of these, negative ions have the effect of calming and resting people in the atmosphere. In particular, it has been reported from many test results that at the time of bedtime, the negative ions cause deep and peaceful sleep.

[0003] In addition, a health method using a very small amount of radiation that does not adversely affect the human body and a health promotion method using a material carrying a radioactive substance have been conventionally known. It is said to be an effect accompanied by the occurrence of. For example, bathing in a hot spring containing a natural radioactive substance such as radon, radium, uranium, etc. is said to be good for the treatment of rheumatism, neuralgia, etc. because the effect of keeping the body warm after the bath is good and it is difficult to cool the water. Drinking this hot spring is also recommended as a treatment for people with weak gastrointestinal tract.

By the way, for example, Japanese Patent Publication No. 62-29884
In the publication, a health material is proposed in which natural radioactive rare elements such as radon and thoron are bonded to fabric using the fact that negative ions are generated in the air by the energy radiated from the radioactive material as described above. doing.

[0005] The health material proposed in the above prior art is prepared by dispersing a fine powder of a natural radioactive rare element mineral in a highly viscous binder liquid (resin liquid) having a high resin concentration, using a roll coating method, and a gravure method. Various coating methods such as roll method, screen method, doctor method, spray method, etc.
The fabric surface is coated and coated. Here, the reason for using a highly viscous binder liquid is that
Since the mineral powder has a large specific gravity, if the binder liquid is thin and the viscosity is low, the mineral powder will sediment, and it is difficult to uniformly disperse the mineral powder in the binder liquid. This is because they can only keep their state for a short time.

However, the textured fabric obtained in this manner has a high texture due to the high resin concentration of the binder liquid, and clothing, bedding and the like obtained by sewing the fabric have a poor touch. In particular, since the binder liquid having a high viscosity does not penetrate into the inside of the fabric, that is, the inside where the yarns intersect or the surface of the single fiber constituting the yarn, and adheres only to the surface of the fabric, In order to achieve a sufficient effect, that is, to sufficiently generate negative ions, it is necessary to apply a larger amount of the binder liquid, and there is a problem that the work cloth is hardened more. In addition, there is a problem that when washing, a large amount of mineral powder is dropped off from the thick coating film on the surface of the fabric.

Further, Japanese Unexamined Patent Publication No. 7-258909 and Japanese Patent Publication No. 8-8934 disclose that a fine powder of a natural radioactive rare element is mixed into a synthetic resin or a solution for forming artificial fibers in a step before spinning, and the spinning is performed. Has been proposed for the fibers.

[0008]

However, a method of mixing fine particles of a natural radioactive rare element into a synthetic resin or a solution for forming an artificial fiber in a process prior to the spinning of the prior art and spinning the same has been obtained. There is a problem that the fine particle powder is uniformly dispersed in the fiber. The fine particle powder present in the fiber has a weak energy for generating negative ions, the fine particle powder present on the fiber surface is also thinly coated with the polymer, and is exposed to the air to directly transfer the energy into the air. It is difficult to radiate. Further, if the fine particle powder is added at a concentration high enough to expose the fine particle powder from the fiber surface, the fine particle powder may agglomerate or the mechanical strength of the yarn may be reduced, making it difficult to form the yarn itself. Problem.

In order to solve the above-mentioned conventional problems, the present invention provides an inorganic material which is soft, has a good touch, has high washing resistance, can efficiently generate negative ions, and can be processed by post-processing after fabric formation. An object of the present invention is to provide a fine-particle-attached fabric and a method for producing the same.

[0010]

Means for Solving the Problems In order to solve the above-mentioned problems, an inorganic fine particle-adhered fabric according to the present invention comprises an inorganic material which emits energy for generating negative ions in the air on the surface of a fiber constituting the fabric. It has a configuration in which fine particles are attached.

In the structure of the present invention described above, the inorganic fine particles which emit energy for generating negative ions in the air are, for example, monazite, bastnaesite, etc., energy for dissociating gas molecules in the air into ions. Refers to a single substance of a magnetic mineral that emits fine particles, or an inorganic substance containing fine particles of the magnetic mineral. The inorganic substance may be used as a mixture by adding ceramic fine particles that emit far-infrared rays into the air. Of the magnetic mineral particles, monazite is preferable because of its high negative ion generating effect.

In such a processed fabric of the present invention that generates negative ions, since inorganic fine particles that emit energy for generating negative ions in the air are attached to the surface of the fiber constituting the fabric, the fabric is soft and flexible. It is possible to make the fabric feel good. In addition, since the inorganic fine particles are also held on the surface of the fiber constituting the fabric, that is, the surface of the fiber existing inside the fabric, it is difficult to fall off from the fabric during washing, and even if washing is performed repeatedly, negative ions are generated. The action to be generated can be maintained.

In the above-mentioned cloth, the inorganic fine particles are
It is preferable to include fine particles of a magnetic mineral that emits energy for ion dissociation of gas molecules into the air, and fine particles of a ceramic that emits far-infrared rays into the air. With this configuration, the far infrared rays emitted by the fine ceramic particles that emit far infrared rays promote the ion dissociation phenomenon of gas molecules in the air caused by the energy emitted by the fine particles of magnetic minerals, and generate negative ions. It can be generated efficiently.

In the above-mentioned cloth, the weight ratio of the magnetic mineral fine particles to the ceramic fine particles (magnetic mineral fine particles: ceramic fine particles) is preferably in the range of 1: 9 to 3: 7. Within this range, ion dissociation of gas molecules in the air is further promoted, and the generation efficiency of negative ions is further improved.

In the above-mentioned cloth, it is preferable that the fine particles of the magnetic mineral are fine particles of monazite and the fine particles of ceramic are zircon. By doing so, the monazite microparticles and the zircon microparticles having a specific gravity (about 5) close to that of monazite can be uniformly mixed, so that both are adhered to the constituent fibers of the entire fabric at a uniform mixing ratio. As a result, it is possible to obtain a processed fabric in which the action of generating negative ions in the entire fabric is not uneven.

In the above-mentioned cloth, it is preferable that the amount of the inorganic fine particles which emit energy for generating negative ions in the air is in the range of 1 to 10% by weight based on the processed cloth. In the above description, when the amount of the attached inorganic fine particles that emits energy for generating negative ions in the air is less than 0.1% by weight, the amount of generated negative ions tends to decrease. The texture and feel tend to be poor.

Further, in the cloth, it is preferable that zeolite fine particles are further adhered in addition to the inorganic fine particles, and the total amount of these both is in the range of 1 to 10% by weight. As a result, it is possible to obtain a processed fabric which generates negative ions efficiently, is soft and has a good touch, and has an antibacterial and deodorizing effect.

In the fabric, the average particle diameter of the inorganic fine particles emitting energy for generating negative ions is 10 nm to 1.5 μm, or the fine inorganic particles emitting energy for generating negative ions and the zeolite fine particles are used. Has an average particle diameter of 10
It is preferably from nm to 1.5 μm. With such a configuration, the flexibility and feel of the fabric can be further improved.

Next, the method for producing an inorganic fine particle-adhered fabric according to the present invention is a method for producing an inorganic fine particle-adhered cloth to which inorganic fine particles which emit energy for generating negative ions in the air are adhered. The cloth is immersed in a processing solution having a viscosity of 5 to 200 centipoise containing fine particles of an inorganic substance that radiates energy to generate negative ions in the air and a binder resin, squeezed to a predetermined adhesion amount, and then dried and heat-treated. It is characterized by.
According to this method, it is possible to easily attach the inorganic fine particles that emit the energy for generating negative ions in the air to the peripheral surface of the constituent fibers of the fabric, and to effectively generate the negative ions of the present invention described above, and Thus, it is possible to rationally and stably produce a processed fabric having good touch and excellent washing resistance.

In the above method, the inorganic fine particles are
It is preferable to include fine particles of a magnetic mineral that emits energy for ion dissociation of gas molecules in the air, and fine particles of a ceramic that emits far-infrared rays into the air. The addition amount of the fine particles of the magnetic mineral in the processing solution is 0.1-1.
0.0% by weight, added amount of ceramic fine particles is 0.3
It is preferable to set it to 20% by weight. More preferably,
The magnetic mineral is 0.5 to 2.0% by weight, and the ceramics is 0.1 to 10.0% by weight. As a result, a work cloth capable of efficiently generating negative ions can be rationally and stably manufactured.

In the above method, the fine particles of a magnetic mineral that emits energy for ion dissociation of gas molecules in the air are fine particles of monazite, and the fine particles of a ceramic that emit far-infrared rays in the air are zircon. Is preferred. In this way, the specific gravities of the monazite fine particles and the ceramic fine particles are close to each other, and the dispersibility of the two in the working fluid is almost equal. Therefore, both can be dispersed in the entire working fluid at a uniform mixing ratio. it can. Therefore, the action of generating negative ions in the entire work cloth can be made uniform.

Further, in the above method, it is preferable that the processing solution contains zeolite fine particles in addition to the inorganic fine particles and the binder resin which emit energy for generating negative ions in the air. With such a configuration, the processed fabric of the present invention having the above-described antibacterial and deodorizing effects can be produced rationally and stably.

In the above method, a dispersion stabilizer for stabilizing the dispersion state of the inorganic fine particles in the solution is preferably added to the processing solution in a range of 0.01 to 20% by weight. With such a configuration, both the inorganic fine particles that emit energy to generate negative ions in the working fluid, or the inorganic fine particles and zeolite fine particles that emit energy to generate negative ions, maintain a good dispersion state for a long time. While maintaining, the fine particles can be uniformly adhered to the peripheral surfaces of the fibers of the entire fabric during the fabric dyeing process, and a processed fabric having small characteristic unevenness can be obtained.

[0024]

BEST MODE FOR CARRYING OUT THE INVENTION The fabric used in the present invention is a textile product generally used for clothing, bedding, cloth personal belongings and building materials. The raw materials are natural fibers such as cotton, hemp, wool, and silk; cellulosic chemical fibers such as rayon and acetate; synthetic fibers such as polyester, nylon, acrylic, polypropylene, and polyethylene; and mixtures thereof. This can be used as a woven fabric, knitted fabric, felt, non-woven fabric, paper or the like as a fabric. The basis weight of the fabric is not particularly limited, but is usually 10 to 1000 g / m
² , preferably 20 to 500 g / m ² .

The inorganic fine particles that emit energy to generate negative ions in the air attached to the peripheral surface of the constituent fibers of the fabric are magnetic minerals that emit energy to dissociate gas molecules in the air into the air. Fine particles or a mixture of fine particles of this magnetic mineral and ceramic fine particles that emit far-infrared rays into the air.

Examples of the fine particles of the magnetic mineral include fine particles such as monazite and bastnaesite. In addition, there are many types such as tilkerite, formanite, magnetite, aquatite, pistasite, samarskiite, columbite, titanium magnetite, gadolinite, and cutaneite. One or two or more selected from these can be used.

Examples of the ceramic fine particles that emit far-infrared rays into the air include fine particles of zircon, alumina, silica and the like, and one or more selected from these can be used.

Even if only the fine particles of the magnetic mineral are adhered to the peripheral surface of the constituent fibers of the cloth, the cloth can be processed so as to effectively generate negative ions. When both the ceramic fine particles radiating inside are attached to the peripheral surface of the constituent fibers of the fabric, the ion dissociation phenomenon of gas molecules in the air caused by the energy released by the magnetic mineral fine particles releases the ceramic fine particles. This is further promoted by far infrared rays, and negative ions are generated more efficiently.

Further, by attaching zeolite fine particles together with magnetic mineral fine particles to the peripheral surface of the constituent fibers of the cloth, a processed cloth having an antibacterial and deodorizing effect can be obtained. The zeolite is preferably a silver-based zeolite.

The inorganic fine particles that emit energy for generating negative ions in the air (the amount of the magnetic mineral fine particles attached, or the total of the magnetic mineral fine particles and the ceramic fine particles that emit far-infrared rays into the air) Is set to be 1 to 10% by weight based on the whole processed fabric. If the amount of particles attached is less than this range,
The amount of negative ions required to obtain a tranquilizing effect and a health-promoting effect cannot be obtained. If the amount exceeds 10% by weight, the texture and feel of the fabric deteriorate. Also. When both the magnetic mineral particles and the ceramic particles that emit far-infrared rays are attached, the weight ratio (magnetic mineral particles: ceramic particles) is preferably 1: 9 to 3: 7. This is because the ion dissociation phenomenon of gas molecules is promoted to the utmost in this range.

When zeolite fine particles are attached together with inorganic fine particles that emit energy to generate negative ions in the air, the total amount of the inorganic fine particles that emit negative ion generating energy and zeolite fine particles is reduced. 1 to 10 per processed fabric
% By weight. Also, the fine particles of zeolite at this time are such that the quantitative relationship with the fine particles of the magnetic mineral is such that the fine particles of zeolite are used instead of a part or all of the fine ceramic particles that emit far-infrared rays. use.

As the various fine particles such as the magnetic mineral fine particles, those having an average particle diameter of 1.5 μm or less are usually used, and preferably, the average particle diameter is 1.5 μm or less and substantially Use a particle that does not contain particles having a diameter larger than 3 μm. By using fine particles having an average particle diameter of 1.5 μm or less, the flexibility and feel of the fabric can be further improved.

The method for producing the processed fabric of the present invention is not particularly limited as long as it is a method capable of adhering various fine particles such as the above-mentioned fine particles of the magnetic mineral to the peripheral surface of the constituent fibers of the fabric. Various fine particles such as fine particles are dispersed in a processing liquid having a viscosity of 5 to 200 centipoise, preferably 35 to 100 centipoise containing a binder resin and a thickener, and the cloth is dyed with the processing liquid, dried and heat-treated. Thus, it can be manufactured easily and stably. If the viscosity of the working fluid is lower than 5 centipoise, the fine particles settle by their own weight, making it difficult to attach the fine particles to the cloth. If the viscosity exceeds 200 centipoise, the amount of the working liquid adhering to the cloth is not stable, and Since the working fluid does not sufficiently penetrate into the inside of the fabric, fine particles cannot adhere to the peripheral surface of the constituent fibers of the fabric.

The binder resin is a resin such as an acrylic resin, a urethane resin, a melamine resin, an ester resin, or a vinyl resin, which has been conventionally used in fiber processing. The thickener is an ether-based, ester-based, or starch-based polymeric material, such as bissurf 1400 (trade name, manufactured by Kao Corporation, a nonionic emulsion thickener of an alkyl ether polymer), WS Emulsifier 240. (Product name, manufactured by Toyo Ink Manufacturing Co., Ltd., special nonionic activator)
And the like.

It is preferable to use a dispersion stabilizer in order to disperse various fine particles such as fine particles of magnetic minerals in the working fluid for a long time and stabilize the working fluid. As the dispersant stabilizer, various anionic, cationic, amphoteric and nonionic surfactants can be used. Poise 520 (trade name, manufactured by Kao Corporation, carboxylic acid type polymer), Poise 530 (trade name, A carboxylic acid type polymer (a carboxylic acid type polymer manufactured by Kao Corporation) can be preferably used in combination with the above-mentioned thickener. Other examples include Caron 3301 (trade name, manufactured by Lion Corporation, sodium polystyrene sulfonate), POLITY SP-1900 (trade name, manufactured by Lion Corporation, sodium polystyrene sulfonate), Demol EP (trade name, Kao Corporation, carboxylic acid type polymer), Ionnet T-60C (trade name, Sanyo Chemical Industries, Ltd., polyoxyethylene sorbitan monostearate), Neugen EA-137 (trade name, Daiichi Kogyo Seiyaku Co., Ltd.) Polyoxyethylene alkyl allyl ether), Apiagen T-300 (trade name, manufactured by Rakuto Kasei Kogyo Co., Ltd.), Sirrix AK (trade name, manufactured by Clearant Corporation, aliphatic organic acid salt), Marialim AKM-
0531 (trade name, manufactured by NOF Corporation, polyoxyalkylene acid anhydride), POLYSTAR A-1060 (trade name, manufactured by NOF Corporation) and the like. These dispersion stabilizers are usually used in an amount of 0.01 to 20 per whole working fluid.
%, Preferably 0.1 to 10% by weight, more preferably 0.2 to 5.0% by weight. A dispersion stabilizer is incorporated into the processing liquid to stabilize the dispersion state of various fine particles such as magnetic mineral particles for a long period of time, so that it adheres to the entire surface of the fiber evenly from the start to the end of processing. Thus, a work cloth with small characteristic unevenness can be obtained.
