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-deodorizing product is obtained by coating a fabric product made by covering cotton with a cloth body such as a woven or non-woven fabric with a ceramic coating agent consisting of an inorganic filler that has bactericidal, gas-absorbing and gas-degrading properties. The present invention relates to a fabric product made by covering cotton, which has bactericidal properties, far-infrared radiation, and antistatic properties, with a tangible material such as a woven or nonwoven fabric.

[Prior Art] Conventional cloth products made by covering cotton with a tangible material such as woven fabric or non-woven fabric are generally made of various types of cotton, such as cotton cotton made of cotton fibers, cotton cotton made of silk fibers, and synthetic cotton made of chemical fibers. It is simply covered with a material such as various woven or non-woven fabrics, and is widely used in bedding such as futons, various types of clothing, and other fabric products.

These fabric products made by covering cotton with a tangible material such as woven fabric or non-woven fabric are simply sewn and have deodorizing, antibacterial, far-infrared radiation, and antistatic properties. There was no one that had been specially processed to achieve this.

[Problem to be solved by the invention] Conventional cloth products made of cotton coated with a tangible material such as woven or non-woven fabric are manufactured by processing various raw material fibers, various textiles, etc. using conventional methods. Fabric products made by covering cotton with tangible materials such as woven or non-woven fabrics have only been used for bedding, coverings, and various other uses.

In this way, conventional cloth products made by covering cotton with a tangible material such as a woven fabric or a non-woven fabric only have their own unique functions such as heat retention and cushioning properties. It was not possible to achieve (sterilizing) properties, far-infrared radiation, and antistatic properties.

Among these problems, there has been a strong desire to develop cloth products made of cotton having a deodorizing function and covered with a tangible material such as woven or non-woven fabric.

For example, in the case of cloth products made by covering cotton with a tangible material such as woven or non-woven fabric used in bedding, clothing, etc., when used or worn in a hot and humid environment, the bedding, clothing, etc. The inside of the room becomes hot and humid, and due to the sweating effect from the body, the smell of sweat and foreign odors are generated, which is not only unpleasant, but also often bothers others.

Particularly in bedding, etc., mold and various other germs breed, which not only makes the body feel stuffy and uncomfortable, but also absorbs moisture and loses its elasticity, contributing to the growth of mold, etc. there were.

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. can be very noticeable, and this can be a problem for not only the caregiver but also the person himself/herself. It was unbearable. In addition, since clothing such as clothing is used every day, strange odors remain attached to clothing, etc., and accumulate over time.
The discomfort increased each time it was worn.

Therefore, in the past, clothing such as clothing, bedding, and other fabric products were washed or replaced as appropriate whenever abnormal odors, etc. increased, but since they are fabric products that contain cotton, It is difficult to carry out these operations easily, and without the need for such labor, the residue remains on fabric products made by covering cotton used in bedding, clothing, etc. with tangible materials such as woven or non-woven fabrics. It was not possible to remove strange odors, etc.

For this reason, even when clothing, bedding, etc. made of cloth products made of cotton coated with a material such as woven or non-woven fabric are used for a long period of time, they do not generate any odor, and they do not contain dust mites. Woven or made of cotton that has excellent deodorizing and antibacterial properties, as well as far-infrared radiation and antistatic properties, making it comfortable to use and wear without breeding bacteria such as lice and various molds. There has been a strong desire to develop fabric products that are coated with a tangible material such as non-woven fabric.

In addition, when placing a corpse, etc., it has traditionally been common practice to enshrine the body on a mattress and cover it with a thin futon, etc., but this is not limited to cases such as summer. It has been extremely difficult to solve this problem, as people are often bothered by odors from the time the funeral is over until the coffin is removed.

For this reason, there has been a strong desire to develop cloth products made by covering cotton with excellent deodorizing properties with a tangible material such as woven or nonwoven fabric. or,
In addition to bedding, cushions, clothing, etc., inside the refrigerator, in the living room,
In the car, in the shoe closet, in the toilet, in the trash can, in the sink,
There has been a strong desire for the development of a cloth product made by covering cotton with excellent deodorizing properties with a box made of woven or non-woven fabric, which can easily deodorize the inside of a wardrobe, closet, etc.

In addition, the cloth product 1 made by covering cotton with a material such as a woven fabric or a non-woven fabric retains the texture of a conventional cloth product made by covering cotton with a material such as a woven fabric or a non-woven fabric, and has good breathability. There is no change in washability compared to cloth products made by covering unprocessed cotton with a tangible material such as woven or non-woven fabric.

[Effects of the Invention] By being configured as described above, the present invention can achieve the effects described below.

That is, when the cloth products made of the cotton of the present invention coated with a tangible material such as woven or non-woven fabrics are used for clothing such as bedding or clothing, they may not be used or worn in hot and humid environments. Even if bedding, clothes, etc. become hot and humid and a strange odor occurs due to sweating from the body, the odor can be immediately deodorized.

Furthermore, since the present invention has excellent antibacterial (sterilizing) properties, various germs such as mold, mites, and lice do not propagate in bedding, etc., and the bedding can be used cleanly and comfortably.

In particular, since the present invention has an extremely strong deodorizing property, for example, when a corpse or the like is to be laid to rest, the body or the like is placed on a mattress made of a cloth product made by covering the cotton of the present invention with a cloth body such as a woven or non-woven fabric. The funeral can be completed, not only in the summer, but also by covering it with a thin futon made of a fabric product made by covering the cotton of the present invention with a fabric such as woven or non-woven fabric. Until the coffin is removed, the body can be preserved without being bothered by odors and without damaging the body.

Furthermore, since the fabric product of the present invention is a rational far-infrared radiator, when used for bedding, etc., it can increase the heat retention effect to prevent cold in various parts of the body, making it convenient to use especially in winter. It is something that can be done. At the same time, it has excellent hygroscopicity and breathability, making it ideal for fabric products made by covering cotton with a fabric such as woven or nonwoven fabric.

Furthermore, since the present invention has excellent antistatic properties, it is extremely convenient to use, especially in clothing and the like, since no static electricity is generated.
