[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail.

The textile product which can be used for the antibacterial processed product of the textile product of the present invention may be any textile product which can be washed with water. For example, in addition to those produced by processing natural fibers such as cotton, hemp, etc. Examples thereof include fibers obtained by processing fibers mixed with polyester fibers, but the present invention is not limited thereto.

The antibacterial agent which can be used in the antibacterial product of the sizing agent and the textile product of the present invention may be any as long as it contains hiba oil or at least one kind of antibacterial component in hiba oil. Hiba oil is a neutral oil (Thuypsen, paracimen, dihydrocymen, cedrol,
Widrol, etc.) and acidic oils (carbacrol, 1-rosinic acid, hinokitiol, β-drabrin, etc.), and are subjected to steam distillation etc. from waste materials (sawdust, offcuts) etc. generated in the sawing process of Aomori Hiba (Hinoki Asunaro). It is a substance that shows various biological activities to be extracted. As the biological activity, a high antibacterial activity can be mentioned, and among the components of the above-mentioned Hiba oil, hinokitiol and β-drabrin are components exhibiting high antibacterial and antifungal activities. Therefore, as the components having antibacterial properties of Hiba oil, in particular, hinokitiol, β-
Dravling. Furthermore, the antibacterial spectrum of Hiba oil and the components having antibacterial properties of Hiba oil is not limited to general bacteria, but is very wide.Also, the appearance of most resistant bacteria is not recognized, and the property of having a higher mite repellent effect is exhibited. Also has. Furthermore, since Hiba oil and the antibacterial component of Hiba oil have extremely high safety compared to existing drugs in terms of toxicity and carcinogenicity, pharmaceuticals such as pharmaceuticals and cosmetics Use as a preservative for quasi-drugs and foods is also recognized, and there is no safety problem when used for textile products that come into direct contact with the human body, especially the skin, such as shirts. In addition, the above-mentioned Hiba oil and other antibacterial agent components other than the antibacterial component of the Hiba oil, if necessary, depending on the microencapsulation technology to be applied, a required surfactant, a resin serving as a reinforcing agent And the like can be appropriately selected and used.

[0015] In the antiseptic processed product of the sizing agent and the textile product using the sizing agent of the present invention, microcapsules containing the antibacterial agent are used. This is an effective and effective means for solving a new technical problem that simply adding the above-mentioned antibacterial agent to the sizing liquid causes the two components to be easily separated and the sizing operation (work) is difficult. In addition, it can protect the antibacterial agent, which is the content, until it is needed, and when needed, breaks the shell with pressure, heat, etc., and provides a new effect that its function can be exhibited, This is because the shell can be made porous to provide sustained release. The microencapsulation technique is not particularly limited, and may be a conventionally known microencapsulation technique, for example, by dispersing a substance called a core substance (a pharmaceutical, a fragrance, etc.) as fine particles in a polymer solution. Phase separation can be achieved by adding a salt, a non-solvent of a polymer, or another polymer to the solution to reduce the solubility of the wall material (the polymer film that wraps the heart material). Phase separation method (complex coacervation method) in which the core material is coated with the separated and concentrated polymer solution, and the core material is dispersed in a solution in which the polymer is dissolved in a volatile organic solvent. A physical chemical method such as an interfacial precipitation method in which water is dispersed in water, one monomer in a liquid core substance is dissolved, and a liquid of another monomer in which the core substance is dispersed in fine particles is added to this solution. On the surface of fine particles An interfacial polycondensation method in which a condensation reaction is caused to form a polymer film and at the same time microencapsulation, a core substance is dispersed in a polymer solution and dropped into a liquid containing a curing agent to obtain microcapsules. In addition to the curing coating method (orifice method),
Chemical methods such as a tu polymerization method and a solvent volatilization method (these are described in detail in Processing Technology, March 1990, etc.), a drug or an inorganic substance as a core substance, and a waxy substance (paraffin, Melt-dispersion cooling method in which a polymer is melted and dispersed in a liquid or vapor medium, cooled, and the film is solidified to obtain microcapsules. Dissolving in the solvent used as the content to form a polymer film, powdered-bed method in which the core substance is suspended in a gas stream on a fluidized bed, and the film material is sprayed and microencapsulated, etc. Mechanical method,
Further, as a method for making microcapsules containing an antibacterial agent by a relatively easy method, for example, an antibacterial agent (an antibacterial component such as hiba oil or hinokitiol, a surfactant, a reinforcing agent) is added to an aqueous solution in which poval is dissolved. Add a resin (eg, maleic acid-based copolymer resin + modified melamine resin) as an agent while stirring, further stir to form an emulsion, and spray and dry this emulsion with an atomizer while stirring. There is a spray drying method and the like in which spherical microcapsules can be obtained by using these methods, and these known methods can be applied to the present invention by appropriately applying and improving them. The components other than the antibacterial agent, which is a main component of the contents constituting the microcapsules used in the present invention, are not particularly limited, and have a configuration suitable for a conventionally known manufacturing method as described above. The components can be appropriately blended and used.

The above-mentioned microcapsules which can be used for the paste of the present invention and the antibacterial processed product of textile products using the paste can be said to be, so to speak, a micro-container containing a liquid substance. Microcapsule size (particle size)
Is 0.2 to 50 μm, preferably 0.5 to 20 μm, in consideration of the influence such as texture when glued to a fiber product.
m is desirable. If the thickness exceeds 50 μm, it is not preferable that a feeling of incompatibility occurs when gluing is performed. If the thickness is less than 0.2 μm, it is difficult to manufacture, and since the microcapsules are held in the gluing film when ironing or wearing after gluing, the shell of the microcapsules is broken when rubbing the iron or textiles. The advantage of exhibiting antibacterial, deodorant and fragrance effects when required is easily lost.

The paste containing the microcapsules used in the antibacterial processed product of the textile product of the present invention is, in addition to the microcapsules, mainly a paste mainly. The glue that can be used in the present invention is not particularly limited, but is preferably one that easily adheres to the skin, can be easily washed off from textiles by washing with water, has no residual glue, and damages textiles. Natural glue is preferred, but an appropriate amount of synthetic glue may be added to such natural glue. In this case, if the mixing ratio (weight ratio) of the natural glue and the synthetic glue is up to 50:50, even if the synthetic glue is added, the suitable effect of the natural glue described above can be obtained. If the synthetic glue is added beyond this, the problems of the synthetic glue as described below will gradually become apparent. That is, with synthetic glue, it is difficult to easily wash off the textile product by washing with water, and in some cases, the residual glue remains until pressing, and the residual glue darkens the textile product, which may cause the texture of the textile product to be impaired. Care must be taken in its use. Examples of the natural paste include starches (corn starch (corn starch, etc.)), natural rubbers (tragacanth gum, gum arabic, etc.), proteins (gelatin, glue, casein, etc.). Examples of the synthetic paste include polyvinyl acetate, polyvinyl alcohol, sodium alginate, sodium polyacrylate, and polyacrylate. Note that the sizing agent is obtained by adding and dispersing an appropriate amount of microcapsules to a sizing solution obtained by dissolving the sizing agent in a solvent such as water.If necessary, a surfactant, a dispersant,
An additive such as an emulsion stabilizer may be appropriately added. However,
From the viewpoint of preventing deterioration of weather resistance and light resistance after gluing, it can be said that it is desirable to add and disperse only an appropriate amount of microcapsules to a sizing solution obtained by dissolving a paste in water.

The mixing ratio (weight ratio) of the paste and the microcapsules in the paste is usually 40: 1 to 10: 1,
Preferably it is in the range of 30: 1 to 15: 1. If the mixing ratio (weight ratio) of the paste and the microcapsules in the paste is out of the above range, sufficient antibacterial, deodorant, and aroma effects cannot be exhibited, or conversely, due to the release of excessive antibacterial agents,
The aromatic odor may be too strong and cause discomfort.

The form of use of the sizing agent which can be used for the antibacterial processed product of the textile product of the present invention differs depending on whether the entire textile product is pasted or partially pasted. It also depends on whether it is used for commercial purposes such as a laundry shop or used in ordinary households. For example, in the case of gluing the entire textile product, a dipping type in which these textile products can be dipped in the prepared paste, or a partial type, so that a certain amount of textile products that have been washed can be pasted. When gluing on the fabric, seal the glue with a highly volatile spray gas in a spray container so that the glue can be attached only to the area where you want to glue the washed textiles. It is possible to appropriately select a spray type or the like most suitable for the use situation.

The size of the sizing agent which can be used for the antibacterial processed product of the present invention is 0.1 to 2.0%, preferably 0.2 to 2.0%.
The range is 1.0%. If the concentration is less than 0.1%, the gluing is insufficient, so that wrinkles or the like of the fiber product cannot be removed by ironing or pressing, or folds or the like cannot be sufficiently formed. On the other hand, if it exceeds 2.0%, it becomes stiff and the feel is reduced, and the next time the laundry is washed, it is not possible to completely remove the pasted and contaminated glue. Note that the gluing density here is
It refers to a value expressed as (amount of sizing agent attached to fiber product after paste drying / weight of fiber product to be pasted).

In the antibacterial product of the textile product of the present invention having the above-described structure, a part of the shell of the microcapsule is broken when, for example, ironing or pressing is performed after the textile product is glued. Therefore, since the antibacterial property of the textile product is already antibacterial when finished, the antibacterial action can be effectively exerted even during storage until the antibacterial product is used, and more preferably, the antibacterial effect is more gradually reduced. By using release microcapsules, the antibacterial effect during storage can be further enhanced. Furthermore, during use, the microcapsule shell is broken by an external load, such as rubbing, because a part of the microcapsules is maintained in the glued film without being broken. As a result, Hiba oil, which was used as an antibacterial agent, and Hinokitiol, which is an antibacterial ingredient, have the combined odor-preventing and aroma effects.For example, textiles such as shirts remove odors such as sweat. (Deodorizing effect), a forest bathing effect (aroma effect) is obtained by the refreshing aroma of hiba oil and hinokitiol. Also, in the case of beds and sheets, turning over while sleeping causes the microcapsule shell to be destroyed and its aroma effect to provide a comfortable sleep. In addition, antibacterial, deodorant, anti-mite, and mildew-resistant Hiba oil and hinokitiol, which have properties, can be kept clean for a long time until they are replaced.

Further, in the antibacterial processing method for textile products according to the present invention, an antibacterial agent containing at least one component selected from the group consisting of hiba oil and these antibacterial components is included in the sizing solution. The fiber product is glued with a sizing agent in which the obtained microcapsules are dispersed. The processing method of the present invention does not impart antibacterial properties to the fiber itself as in the prior art, so that a new antibacterial processing can be performed each time washing is performed, and excellent antibacterial, antibacterial, deodorant, and deodorant that does not change at all times. It can be said to be a versatile and universal processing means that can properly regenerate mites and fungicides.

[0027]

According to the antibacterial processed product of the textile product of the present invention,
By enclosing the microencapsulated antimicrobial agent in the glued film, a part of the microcapsules is destroyed during the processing, so the antimicrobial effect can be effectively exhibited during storage until the antimicrobial processed product is used . The use of sustained-release microcapsules can further enhance the antibacterial effect during storage. Further, since the shell of the remaining microcapsules is destroyed during use, deodorization and aroma effects can be obtained.

Further, the antibacterial processing method for textile products according to the present invention does not impart antibacterial properties to the fibers themselves as in the prior art, so that the textile products are subjected to special antibacterial treatment for antibacterial and deodorant properties. It is obtained by a simple gluing process that is usually performed at general cleaning shops and homes without
Each time washing is performed, a new antibacterial process can be performed, and the excellent antibacterial, antibacterial, deodorant, mite, and mildew resistance that does not change at all times can be appropriately reproduced.
