BEST MODE FOR CARRYING OUT THE INVENTION With reference to FIG. 1, a description will be given of a deodorizing effect imparting method according to a first embodiment of the present invention in a general case of manufacturing paper products. FIG. 1 is a flowchart showing a manufacturing process of a paper product having a deodorizing effect.

The manufacturing process of this paper product is roughly divided into five stages, a pulping process 1, a conditioning process 2, a papermaking process 3, a finishing process 4 and a commercialization process 5.

In the first pulping step 1, wood chips as a raw material are cooked in a wooden kettle under high temperature and high pressure using a caustic soda-based cooking liquor. By this, fiber (pulp)
After taking out, bleach.

In the next adjusting step 2, the dye and chemicals are mixed with the pulp to improve the quality of the paper which is the base of the paper product. In this adjusting step 2, citric acid (or phosphoric acid) is added. The amount of the citric acid is an amount necessary for the paper to exhibit the deodorizing effect, and is set appropriately according to the amount of the paper to be manufactured.

As a result of the experiment, it was confirmed that phosphoric acid had a stronger deodorizing effect than citric acid. Therefore, when citric acid is added, it is necessary to add it in a larger amount than when phosphoric acid is added. At this time, ascorbic acid may be added at the same time as a citric acid deterioration inhibitor.

In the subsequent paper making step 3, the pulp sent from the adjusting step 2 is diluted with water and then poured on the wire part to form a sheet-like thin paper. Then, after being subjected to dehydration, drying treatment, etc., it is once wound.

In the next finishing step 4, the wound paper is cut into a predetermined size to complete the paper. Then, in the final product production step 5, if necessary, for example, the toilet paper is wound into a roll in a two-layer form, and the tissue paper is cut into a state in which a large number of sheets are folded. Finished products are processed uniquely for each paper product.

Toilet paper manufactured in this way,
Since citric acid (or phosphoric acid) is added to paper products such as tissue paper and disposable diapers, the malodor attached to the paper products can be effectively eliminated by their deodorizing action.

The deodorizing effect imparting method according to the second embodiment of the present invention will be described for the case of producing a synthetic fiber product made of nylon such as stockings. FIG. 2 is a flowchart showing a manufacturing process of a synthetic fiber product having a deodorizing effect.

This synthetic fiber product has a refining step 11, a synthesizing step 12, a polymerizing step 13, a spinning step 14, and a drawing step 15.
And, it is roughly divided into six steps of the commercialization step 16.

First, in the first refining step 11, a specific substance is taken out from petroleum, and in the next synthesizing step 12, a compound forming one unit of fiber is produced. For example, in the case of nylon as a material for stockings, caprolactam is produced from cyclohexane and ammonia.

Then, in the subsequent polymerization step 13, these are linked to form a polymer (polymer).
Add citric acid (or phosphoric acid) at. At this time, ascorbic acid may be added simultaneously as a citric acid deterioration inhibitor. Further, in the spinning step 14, the polymer melted by heating is extruded from the hole of the die by the melt spinning method,
Take up while cooling with air.

In the subsequent stretching step 15, the wound filamentous material is further stretched. Then, in the commercialization step 16, the synthetic fiber thus produced is knitted to obtain a product (stocking).

Since citric acid (or phosphoric acid) is added to this synthetic fiber product, it is possible to effectively eliminate it by decomposing a bad odor such as body odor adhering to the product due to its deodorizing effect.

The deodorizing effect imparting method according to the third embodiment of the present invention will be described for the case of cat sand 20 which is a pet product. FIG. 3 is an explanatory diagram showing a method for manufacturing cat sand 20 having a deodorizing effect.

This is to add the amount of citric acid (or phosphoric acid) necessary for exhibiting the deodorizing effect to the finished cat sand 20. The addition amount of citric acid or the like is appropriately set according to the amount of cat sand 20. By adding citric acid or the like, the cat sand 20 has a deodorizing action, and the malodor attached to the cat sand 20 can be decomposed to effectively eliminate it.

The present inventor requested an experiment to the Hiroshima Prefectural Food Technology Center in order to confirm the deodorizing effect of citric acid used in the present invention. In this experiment, 0.1 ml of a 1% concentration ammonia solution (diluted with ethanol) was added to 5 liters of an aqueous solution containing 2.03 mg of citric acid in an Erlenmeyer flask (volume of 1 liter), stirred, and then sealed. . Then, after standing for 60 minutes at room temperature, the ammonia concentration was measured using No. 3L for ammonia gas detector tube (manufactured by Gastec). As a result, the ammonia concentration was greatly reduced from the initial 28 ppm to 3 ppm. From this, it was confirmed that citric acid exerts an excellent deodorizing effect.

[0039]

According to the deodorizing effect imparting method of the present invention, the amount of citric acid necessary for exhibiting the deodorizing effect is used as a raw material for producing paper products and textile products. Alternatively, since phosphoric acid is added, the malodor attached to the paper product or the like can be eliminated by the action of the citric acid or phosphoric acid. As a result, the surrounding living environment can be improved.

Further, according to the deodorant product according to the third aspect, since the amount of citric acid or phosphoric acid necessary for exhibiting the deodorant effect is added to the raw material for producing the paper product, The paper product can effectively eliminate the bad odor attached to it. Therefore, the living environment is improved.

Furthermore, according to the deodorant product of claim 4, since it is produced by adding the amount of citric acid or phosphoric acid necessary for exhibiting the deodorant effect to the raw material for producing the textile product, The textile product can exert a deodorizing effect.

Further, according to the product with deodorant action according to claim 5, the amount of citric acid or phosphoric acid necessary for exhibiting the deodorant action is added to the finished product of cat sand which is a pet product. Therefore, the bad smell attached to the cat sand can be effectively eliminated.
