Abstract

PURPOSE:To improve the deodorizing power by suppressing the propagating of microorganisms which cause the generation of discomfortable odor by constituting the title agent from the water-soluble constituents contained in bamboo or the activated bamboo. CONSTITUTION:An absorptive/releasing liquid agent is made of bamboo or activated bamboo as raw material, and manufactured by extracting the water-soluble constituent. The bamboo as raw material may be raw bamboo or dried bamboo. In order to activate bamboo, steam boiling by the overheated steam having a temperature of 80-180 deg.C and a high pressure is carried out, and then the bamboo is dried and pulverized, and the produced powder is used. As the powdered substance of the activated bamboo, can be used the dry-distilled bamboo. Further, even in the case where the raw bamboo is used as raw material, the bamboo is pulverized or division-processed to form the small granules and used. When the water-soluble constituent is extracted, the air passing through an aero-magnetizer is introduced into water, and the powdered material of bamboo or the activated bamboo is immersed into the water, and the extracted liquid is obtained by filtering the solid portion.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides an absorbing/releasing liquid agent that has deodorizing properties effective for environmental hygiene and has aromatic properties, a method for producing the same, and a fabric impregnated with the absorbing/releasing liquid agent. Regarding.

[Conventional technology]

In general, in addition to solid porous substances such as activated carbon and zeolite, various liquid deodorizers are known as deodorizers for decomposing organic odors, body odors, cigarette odors, pet odors, and other household odors.

Such liquid deodorizers usually contain organic acids such as malic acid and citric acid or their salts, metal salts such as ferrous sulfate and aluminum sulfate, aldehydes such as glyoxal, and others as deodorizing ingredients. Some contain glycols such as propylene glycol and organic acid esters such as lauryl methacrylate.

These liquid deodorizers can be applied to a wider range of subjects than solid porous substances, and are easier to add to fabrics and foods, but they are not necessarily safe and their use is restricted. was. Furthermore, such liquid preparations having deodorizing properties rarely emit fragrance, and fragrances are often added separately.

[Problem to be solved by the invention]

As described above, in the conventional technology, there is a problem that there is no absorbing and releasing liquid that has both the ability to absorb odor components and the ability to release aromas, and is also highly safe for the human body.There is an urgent need to solve this problem. was an issue.

[Means and Actions for Solving the Problems] In order to solve the above problems, in the present invention, the absorption/release liquid agent is composed of a water-soluble component contained in bamboo or activated bamboo. It is also possible to add a sanitary finishing agent, which is a metal compound, to the absorbing/releasing liquid agent and to allow the sanitary agent to be soaked into the fabric. In addition, bamboo activated by superheated steam is immersed in water that has passed through a magnetic field to dissolve quasi-activated oxygen to extract water-soluble components to produce an absorbing and releasing liquid.

The absorbent-release liquid agent extracted in this way contains a wide variety of extracted components, and it is estimated that the interaction between these components generates the bamboo fragrance and strong deodorizing power. The absorbing/releasing liquid agent to which the sanitary finishing agent has been added prevents or suppresses the growth of microorganisms that cause malodor, such as fungi that decompose cellulose or proteins, so that the deodorizing ability is enhanced.

In addition, according to the above-mentioned method for producing absorbing and releasing liquid agents, the reactivity of oxygen semi-activated by magnetic treatment is slightly increased, and a considerable amount of oxygen can be dissolved in water, exceeding the oxygen saturation amount at room temperature and normal pressure. It is presumed that this dissolved oxygen facilitates the elution of odor components, water-soluble deodorizing components, and water-soluble components existing in the tissues of bamboo into water.

〔Example〕

The absorbent-release liquid agent of the present invention is produced by extracting water-soluble components from bamboo or activated bamboo as a raw material.

In this case, the bamboo used as the raw material is not particularly limited, and may be raw bamboo or dried bamboo. In addition, to activate this bamboo, it is boiled in high-pressure superheated steam at a steam temperature of 80 to 180°C, and then dried and crushed to form powder (average particle size of 20 plN to 5 mm). used as raw material.

As such activated bamboo powder, carbonized bamboo (for example, Kiyora, manufactured by Takeizumi Sangyo Co., Ltd.) can be used.

In addition, even when raw bamboo is used as a raw material, it is crushed or divided into small particles.

The water-soluble components contained in bamboo or activated bamboo are extracted by the following procedure. That is, air that has passed through an air magnetizer (for example, Air Magnetizer Type A manufactured by Chuo Neki Co., Ltd.) is aerated into water, and then bamboo or activated bamboo powder is immersed in this water to form a solid. The fraction was separated to obtain an extract.

The above-mentioned air magnetizer combines a plurality of permanent magnets to form a magnetic field of about 7200 Gauss inside, and narrows the flow path in this strong magnetic field to pass air at high speed to remove the particles contained in the air. The molecular oxygen is semi-activated by activating the oxygen molecules.

The sanitary finishing agent, which is a metal compound added to the absorption/release liquid extracted as described above, is copper naphthenate, Cu-
Examples include organocopper compounds such as 8-quinolyl-1-, organozinc compounds such as Zn-dimethyldiocarbamate and zinc naphthenate, organotin compounds such as triethyl-0-octyltin and diethylphenyltin acetate.

In addition, the fabric impregnated with the above absorption-release liquid may be cotton,
In addition to rayon, any fiber material can be used without limitation.

Experimental example: Oxygen semi-activated by an air magnetizer (manufactured by Chuo Neki Co., Ltd.: Air Magnetizer Type A) was aerated into water, and the amount of dissolved oxygen per liter at a water temperature of 26°C was 9.6 mg (oxygen at the same temperature). Bamboo or activated bamboo fine powder (manufactured by Takeizumi Sangyo Co., Ltd.: Kiyora, average particle size 0.5 mm) was soaked for 24 hours in 100 liters of water with a saturation level of 7.99 mg per liter. Thereafter, the solid content was separated to obtain 5 liters each of absorption-release liquid agents 1 and 2, which are examples of the present invention.

In order to confirm the deodorizing properties of the absorbent/release liquids thus obtained, 20 g of each of absorbent/release liquid 1 obtained from bamboo and absorbent/release liquid 2 obtained from activated bamboo fine powder were evaporated. The container was placed in a glass container with an area of 58 d, and then sealed in two polycarbonate desiccators (inner capacity: 18 liters) with 0.4 d of a 10-fold diluted solution of reagent grade ammonia water, and left at room temperature for 15 minutes in the desiccator. The ammonia concentration in the space inside was measured by the detector tube method. The results are shown in Table 1. Furthermore, as Comparative Examples] and 2, measurement values were determined in the same manner as above for commercially available liquid deodorizers and solid granular deodorizers, respectively, and the results are also listed in Table 1.

Table 1 As is clear from Table 1, absorption-release liquid agent 1.2 is
It adsorbed ammonia as well as or better than the deodorizer of Comparative Example 1.2.

In addition, in order to confirm the deodorizing performance when the absorption-release liquid is attached to fabric, 100 g of the absorption-release liquid was diluted with 900 g of water in which semi-activated oxygen was dissolved, and then this diluted solution Heat and keep at 80°, add 20 g of dye (Multi, manufactured by Guillon Japan Ltd. in the UK) and 2 ounces of salt for color fixing.
55 g of 100% rayon fabric was immersed in the mixed solution for about 20 minutes, and then dried with hot air at 100°C to obtain a processed fabric. In addition, processed fabric B was processed in exactly the same manner as above except that 0.05 to 0.15% of an organic tin compound was added as a sanitary agent to the diluted solution of the absorbing and releasing liquid.
I got it.

Next, add 1 liter of reagent special grade ammonia water to each of two polycarbonate desiccators (inner capacity 18 liters).
0.4 ml of the 0x diluted solution and 55 g of processed fabric A were placed in the desiccator, sealed, and left at room temperature for 15 minutes, 20 minutes, and 25 minutes, respectively, and the residual ammonia concentration in the space inside the desiccator was measured by the detection tube method. The results are shown in Table 2. As a comparative example, the same experiment was conducted on fabric C which was processed in exactly the same manner as above, except that no absorption/release liquid was used, and the results are also shown in Table 2.

As is clear from Table 2, processed fabric A adsorbs ammonia better than fabric C, and it is estimated that it also adsorbs amine-based odors as well. In addition, treated fabric B, in which a sanitary agent, which is a metal compound, was added to the absorbing and releasing liquid agent also adsorbed ammonia well.

In addition, in order to confirm the safety of water-soluble components contained in activated bamboo, lead, cadgolum, arsenic, chromium, mercury,
Quantitative analysis of nitrogen dioxide was performed. The results are shown in Table 3.

The amount of cadmium detected in Table 1 and Table 3 is within the range that is considered to be non-hazardous as a content in food. It was also estimated that the safety of the sex liquid was high. In addition, similar quantitative analyzes were conducted on unactivated bamboo powder, particularly for arsenic and lead, and similar results were obtained, confirming its safety.

〔effect〕

As is clear from the above description, the absorbent-release liquid agent of the present invention has both the adsorption of odor components and the aromatic properties of natural bamboo to function effectively, and is manufactured using bamboo as a raw material that is safe for the human body. Because of this, it has high industrial utility value as it can be mixed into textile products, foods, and other daily necessities.
