問題かある。(Prior Art) Cellulose fibers have excellent water absorption properties and are used in many fields, but on the other hand, they have the disadvantage of being easy to breed bacteria. A known method for imparting antibacterial properties to cellulose fibers is to bond a quaternary ammonium compound to cellulose fibers using an organic silicone compound as a crosslinking agent. However, it is known that the treated material thus obtained generates toxic substances when incinerated. Also, as seen in Japanese Patent Application Laid-Open No. 57-51874,
A method of treatment with an organic silane compound having a cationic active group is also known. In any case, these methods are extremely complicated, and furthermore, there are problems in terms of sustainability of effects and safety.

まれていた。(Problem to be solved by the invention) Conventional methods for imparting antibacterial properties to cellulose fibers all use synthetic drugs as antibacterial-producing ingredients, and they do not come in contact with food or tableware. When applied to, for example, dish towels, there is a problem in terms of safety. Furthermore, as mentioned above, when disposed of by incineration, there is a risk of carcinogenic substances being generated, which poses the risk of causing pollution. Also, depending on the application, it may be necessary to wash the fibers frequently, and conventional methods cannot provide satisfactory antibacterial durability. It is safe from such things,
The development of durable antibacterial cellulose fibers has been awaited.

。Is it well known that copper compounds exhibit antibacterial effects?
When cellulose fibers are immersed in a solution of copper compounds,
Alternatively, if heat treatment is performed while the cellulose fibers are immersed, the copper compound cannot be firmly bonded to the cellulose fibers. When the cellulose fibers are washed with water after these treatments, almost no copper remains in the cellulose fibers.

The present invention relates to a method for producing an antibacterial cellulose fiber product, which is characterized by heating in a gas after drying if necessary; (2) the method according to (1) above, wherein the heating temperature is 60°C or higher. As the cellulose fiber product used in the present invention, any material having a cellulose skeleton can be used. Examples include cotton, linen, rayon, cupro, pulp, paper, and the above-mentioned cellulose fiber products. As such, it is not limited to these. Any copper compound can be used as long as it is soluble in a solvent, or if water is used as a solvent, copper sulfate, copper nitrate, copper acetate,
It is preferable to use a copper salt such as cupric chloride. As the solvent, any solvent that dissolves the copper compound, such as water, acetone, or alcohol, can be used, or it is usually preferable to use water. The concentration of the copper compound in the solution varies depending on the amount desired to be supported on the cellulose fiber product, and is usually 0.05% to 2% by weight. After soaking the cellulose fiber product in the copper compound solution, the squeezing rate (weight of the solution absorbed by the cellulose fiber product after impregnation and squeezing/weight of the cellulose fiber product before impregnation) is 50% to 500%,
Normally, it is preferable to squeeze at a reduction ratio of 50% to 200%. Note that the temperature at which the cellulose fiber product is immersed in the copper compound solution is not particularly limited. The immersion time is also not particularly limited, and is preferably carried out until the copper compound solution is sufficiently permeated into the cellulose fiber product, and 30 seconds of immersion is usually sufficient.

採用できる。There is a tendency that the shorter the heating time is, the higher the temperature is heated. The type and shape of the cellulose fiber product used,
The heating conditions differ depending on the type of copper compound. For example, when imparting antibacterial properties to cotton products using an aqueous solution of copper sulfate, heating conditions may vary depending on the type of copper compound.
It is preferable to heat for 5 minutes or more. As a heating method, any of the following heating methods can be employed, including heating by passing hot air between heating high-temperature rollers, heating by passing through a tunnel type heater, and heating by a thermal convection type heater.

An antibacterial cellulose fiber product can be obtained by washing with 506C warm water or water to remove unreacted copper compounds. The copper-reacted cellulose fiber product obtained in this way can be washed in a normal manner, for example, according to JIS L 02.
Even after repeated washing according to the method specified in 17103, the copper content decreases only slightly. This indicates that the copper compound is not simply physically attached to the cellulose surface, but is chemically bonded to the cellulose molecule, and is linked to the many hydroxyl groups present in the cellulose molecule. This shows that copper is bonded to form a copper-cellulose complex. The treatment for imparting antibacterial properties using copper compounds to the cellulose fiber products shown above is as follows:
The dyeing may be carried out after the cellulose fiber product is dyed in advance with a dye such as a direct dye. Alternatively, it is also possible to dye directly with a dye after performing the antibacterial property imparting treatment.

It was immersed in a 0.4% by weight aqueous copper acetate solution at 30°C for 2 minutes and squeezed at a squeezing rate of 205%. After drying at 45°C for 2 hours,
Heat treatment with hot air was performed in air at 150°C for 3 minutes. Then, it was washed with warm water at 40°C to remove excess copper salt, and then dried to obtain antibacterial rayon taffeta. The copper content in the rayon taffeta thus obtained was 660p.
It was pm. Table 2 shows the results of an antibacterial effect test conducted in the same manner as in Example 1.
