[Prior Art] Conventional cottons such as cotton cotton made of cotton fibers, cotton cotton made of silk fibers, and synthetic cotton made of chemical fibers are widely used in various fields, and these cottons are, for example, futon cotton,
Clothing liners are widely used as part of various clothing, bedding, and other products.

[Problems to be Solved by the Invention] Conventional cotton has been made by processing various raw material fibers using conventional methods, and these cottons have only been used for various purposes.

In this way, conventional cotton only has specific functions such as heat retention and cushioning properties. I couldn't.

Among these issues, there has been a strong desire to develop cotton with a deodorizing function.

In a hot and humid environment, the inside of bedding, clothes, etc. that have been used or worn become hot and humid, and due to the sweating effect from the body, the smell of sweat and other unpleasant odors occur, making it unpleasant. Not only that, but he often caused trouble for others as well.

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 bearable.

In addition, since clothes and other clothing items are used every day, foreign odors and the like remain on the clothing, accumulate over time, and cause discomfort each time the wearer wears them. Ta.

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 it is difficult to perform these tasks easily, and It has not been possible to remove residual odors from cotton used for bedding, clothing, etc. without the need for additional labor.

For this reason, even if clothes, bedding, etc. made of cotton are used for a long period of time, they will not emit strange odors, and will remain comfortable as dust mites, lice, and various types of mold and other bacteria will not grow. Deodorizing, anti-killing that can be used and worn
There has been a strong desire to develop cotton that has excellent bactericidal properties, far-infrared radiation, and antistatic properties.

Furthermore, when placing a corpse, etc., it has traditionally been common practice to enshrine the body on a futon and cover it with a thin futon, etc. From the time the coffin was completed until the coffin was removed, people were often bothered by odors, and it was extremely difficult to solve this problem.

For this reason, there has been a strong desire to develop cotton with excellent deodorizing properties.
