ることと、条に練りこみができぬという欠点があった。In addition to those made of silver or silver alloys and zeolites, there are also chips made of copper or copper alloys with aged surfaces made by the same applicant, which have antibacterial effects that can be used in drinking water. The wood does not seem to be able to meet the peaks so far, and the chips described above require 15 steps to make and have the disadvantage that they cannot be kneaded into strips.

性の粉状物を得ることができる。Example (A) Copper or copper alloy powder is heated in a scattered state, dropped into a book, rapidly cooled, and then heated and dried. As a result, although the effect is inferior to the same applicant's chip which added 15 steps, it will open up fields of use that could not be achieved before, such as kneading it into thread and using it continuously. In cases where the water is replaced over a period of time, or in cases where new water comes into contact with a certain cycle, such as in a water purification unit, if the powdered material in question is replaced at intervals of one year or less, the usage effect will be sufficient. Some antibacterial powders can be obtained.

When twice the amount of water was placed in a container and stored for three years, the number of common bacteria per ml of water was 28.

たり、同じ効果を得ることができることになった。Based on the results of (a) and (b) above, it is known that copper or copper alloy chips with aged surfaces have the effect of suppressing bacterial growth, and this effect does not deteriorate even after three years. It will be done. Since the product according to this application is a powder, it is inferior to the above-mentioned chip in terms of durability of the effect.
Although it is unavoidable, since it is a powder, the same effect can be obtained for a considerable period of time by using only part of the processing method for chips.

It is kneaded at the raw material stage of synthetic fiber yarn and then spun.
Using 100% or only a portion of this thread, antibacterial fabrics are made using cotton thread, nylon thread, Tetoron thread, acrylic thread, urethane thread, etc. However, the kneaded synthetic yarn filament (2) is
When looking at the cross section, as shown in the figure, several to ten antibacterial powder particles (1) are scattered, and the space is filled with synthetic fiber material (
3) is filled in the form of a binder.

毒性が無いという利点もある。Furthermore, Company K's antibacterial nylon yarn, which contains Company S's antibacterial zeolite at the raw material stage, has the effect of killing E. coli (according to Company K's tests, 50% antibacterial nylon yarn and 100% antibacterial zeolite) % of cases, E. coli reached 99% after 5 hours.
In a test conducted by Company A using the shake flask method, 97% of the product is said to be killed. However, when mixed with the antibacterial yarn of this invention, which has antibacterial properties against general bacteria, it becomes effective against general bacteria and Escherichia coli, and when used for drinking water,
It also has the advantage of being non-toxic.

効果は、前記した糸の場合と変わるところがない。Note that the surface-aged copper or copper alloy powder according to the present invention may be mixed at the raw material stage and then made into a porous film-like material, or a paper-like material may be made using this as a binder. When the powder comes into contact with water, the effect is the same as in the case of threads as described above.

とができる。Effects of the Invention Copper or copper alloy powder exhibits an antibacterial effect as is widely known, but as in the case of silver, the surface eventually turns black and the antibacterial effect is drastically diminished. However, the surface-aged copper or copper alloy chip made by the same applicant does not darken during use, and its effectiveness is 3.
It is perishable for over a year, and you won't feel sick if you drink the soaked water, as you would with untreated copper. Although the powder according to the present invention is less effective and less perishable than the above-mentioned chips, it can be used by kneading it into threads, films, paper-like materials, etc. It is similar to a more well-known material and can be effectively used as an antibacterial material that can be used directly in drinking water.
