Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a metal oxide having binding properties, far-infrared radiation, and antistatic properties, a resin-based polymer having binding properties, and an antistatic property.
A deodorizing and anti-bactericidal product made by coating textiles, knitted fabrics, and other fabrics with a ceramic coating agent consisting of an inorganic filler that has bactericidal, gas adsorbing, and gas decomposing properties.
The present invention relates to health-promoting fabrics, knitted fabrics, and other fabrics that have bactericidal properties, far-infrared radiation, and antistatic properties.

[Prior Art] Conventional woven fabrics, knitted fabrics, and other fabrics are, for example, made by spinning or twisting bundled fibers into yarn, which is made through processes such as knitting and weaving, and non-woven fabrics. etc. are made by mechanically intertwining fibers or by chemically or thermally treating them. These woven, knitted, and other fabrics are widely used as various clothing, bedding, and other fabric products.

[Problems to be Solved by the Invention] Conventional woven fabrics, knitted fabrics, and other fabrics are made from yarn through processes such as weaving and weaving, or by mechanically, chemically, or thermally treating fibers. Various cloth products have been formed by simply using the cloth and sewing it into a desired shape.

In addition, there are some fibers in which the fibers themselves are specially processed in order to improve deodorizing properties, but they have not been able to achieve a deodorizing effect.

In this way, woven fabrics, knitted fabrics, and other fabrics only have their own specific functions, and for example, it is not possible to achieve deodorizing properties, antibacterial properties, far-infrared radiation, and antistatic properties. Ta.

Among these issues, for example, when it comes to clothing, etc., in hot and humid environments such as summer, the inside of the clothes that are worn becomes hot and humid, and the sweat from the body causes sweat odor and foreign odors. Not only was this occurrence unpleasant, but it often caused inconvenience to others as well.

Similarly, bedding, etc., not only smells of sweat and generates unpleasant odors due to the sweating effect of the body, but also mold and other various germs breed, making the body stuffy and unpleasant. Not only that, but it absorbs moisture and loses its elasticity, which is a factor in the growth of mold and the like.

In particular, bedding and the like cannot be dried in the sunlight during the rainy season, which not only damages the bedding but also has a negative impact on the body.

In addition, in cases such as elderly people who are bedridden, it is difficult to frequently change bedding, etc., and the odor emitted from the futon etc. is so strong that it is unbearable not only for the caregiver but also for the patient. It was something.

Furthermore, since clothing such as clothing is used every day, the odor remains attached to the clothing and accumulates over time, resulting in increased discomfort each time the clothing is worn.

Therefore, in the past, clothing and other fabric products were washed or replaced whenever the odor increased.
It has not been possible to remove the odor remaining on the fabric without requiring these steps.

Therefore, even when cloth products made of woven, knitted, or other fabrics are used for a long period of time, they do not generate any strange odor, and they do not breed dust mites, lice, or various types of mold, making them comfortable to use and wear. There has been a strong desire to develop woven, knitted, and other fabrics for health promotion that have excellent deodorizing and antibacterial properties as well as far-infrared radiation and antistatic properties.

When the ceramic coating agent 3 constituting the present invention is coated on the fabric 1, the porous surface of the coating formed by the zeolite constituting the coating agent 3 adsorbs gas (odor) and absorbs copper ions or silver ions. Ozone, which is generated from metal ions consisting of, immediately decomposes this.

That is, this deodorizing effect is achieved by decomposing odor adsorbed on the active surface of the coating film by active oxygen.

As described above, the ceramic coating agent 3 constituting the present invention adsorbs all kinds of odors and decomposes them with metal ions consisting of copper ions or silver ions, so its gas (odor) decomposition ability deteriorates over a long period of time. There's nothing to do.

In particular, due to the action of titanium oxide, the deodorizing power can be maintained for a long time without deteriorating.

Therefore, by coating the fabric 1 of the present invention on cloth products such as clothing and bedding that require deodorization and deodorization,
