Description

TECHNICAL FIELD The present invention relates to a novel method for producing a deodorant fiber product, and more specifically, a deodorant composition containing a plant deodorant extract as an active ingredient, and a cellulose-reactive type. The present invention relates to a method for treating a fiber product (yarn, knitted fabric, woven fabric, non-woven fabric, etc.) with a mixed liquid of a water repellent and a resin finishing agent to produce a fiber product having excellent deodorizing action with excellent washing durability. .

[Prior Art] It is well known that there are substances having a deodorizing action in plant components, and some of them have already been put into practical use as deodorants.

For example, JP-A-50-160434 discloses a deodorant composition for a gas containing a rubber malodor containing chlorophyll and an essential oil containing a celldren compound, and JP-A-58-160434.
61751 and JP-A-59-66 describe that certain extracts of Lamiaceae plants have a deodorizing effect on sulfur compounds.

The mechanism of the deodorizing effect of extracts from these plants is not clear, but redox action by polyfilin metal complex compounds such as chlorophyll, or flavone compounds such as flavanols and flavonols or fueradrene, terpinene, pinene, etc. It is presumed that the deodorizing effect is produced by the complex action of the inclusion compound, addition action, and neutralization reaction of the terpene compound and many other organic polymers.

Deodorants containing extracts from these plants as active ingredients have few problems such as chemical damage such as chemicals and environmental pollution, and are added to shampoo, hair tonic, soap, toothpaste, mouthwash, etc. It is used for many purposes such as deodorizing toilets and toilets, deodorizing factory exhausts, filtering air cleaners, deodorizing wallpaper, and blending into foods such as chewing gum and candy.

However, many of the deodorant components extracted from these plants are soluble in water, and those processed into fibers with the deodorant component alone have the drawback that the deodorant active ingredient will dissolve out during washing and the effect will not continue. is there.

[Purpose] The inventors of the present invention have made earnest studies to eliminate the above-mentioned drawbacks in the deodorant containing a deodorant component extracted from a plant as an active ingredient, and as a result, the deodorant and the cellulose-reactive water repellent have been found. The present invention has been completed by finding a processing method in which the deodorizing effect of the processed fiber is repeatedly maintained by washing with a resin processing agent and, optionally, a catalyst after the heat treatment.

[Structure of the Invention] According to the present invention, a cellulose-reactive water repellent and a resin finishing agent are blended with one or a compound of a flavone compound, a terpene compound, or a porphyrin metal complex compound as a deodorant. Provided is a deodorant textile product having excellent wash durability, which is characterized by treating the textile product with a mixture.

The mechanism by which the deodorizing effect of the textile product processed by the mixture is maintained after repeated washing is not clear, but the deodorant component is firmly fixed to the fiber by the synergistic action of the cellulose-reactive water repellent and the resin finishing agent. It is presumed to be because.

The feature of the present invention resides in that the component having a deodorizing effect present in the plant is used in combination with the cellulose-reactive water repellent and the resin finishing agent.

Then, the components having a deodorant effect (hereinafter referred to as "deodorant component") present in the plant used as an active ingredient in the deodorant composition of the present invention include the following.

(A) Flavone compounds: flavones (eg, flavones), flavonols (eg: rutin), isoflavones (eg: genistein, daidzein), flavanones (eg: hespentine), flavanols (eg: fustin, alpinone) Or these two
A mixture of more than one species.

(B) Terpene compound: For example, pinene, terpinene, ferrandrene, camphorene, limonene, cazinene, vidaborene, camphorene, or the like, or a mixture of two or more thereof.

(C) Porphyrin metal complex compound: For example, chlorophyll, chlorophyllin sodium salt and the like.

These compounds may be pure products, but normally, those in the form of extracts from plants are sufficient. In addition, these compounds may be used alone or in combination of two or more kinds.

For example, as those containing a large amount of flavone compounds, the camellia plants described in JP-A-58-61751, for example, tea, mountain tea flowers, camellia, sakaki, water from the leaves mainly such as hisakaki, alcohol solvents, Extract with a ketone solvent.

Alternatively, dry-distilled liquids of these plants may be mentioned, and as those containing a large amount of terpene compounds, dry-distilled liquids of conifers already known, for example, red pine, cedar, lawson, hinoki tree, cypress, etc. are suitable.

Examples of the cellulose-reactive water repellent used in combination include fluorine-based, silicon-based, and alkylethylene urea-based compounds.

Examples of the fluorine-based water repellent include copolymers containing a perfluoroalkyl ester as a main component, and examples of the silicon-based water repellent include methylhydrogensiloxane.

Alkyl ethylene urea type water repellents are represented by the following formula synthesized from isocyanate dimer, monoethanolamine and higher alkyl isocyanate. The following formula, which was synthesized from the above compound, cyclopropane monocarboxylic acid, monoethanolamine and higher alkyl isocyanate Compounded products of the compound (trade name: palladium, manufactured by Ohara Palladium Chemical Co., Ltd.) can be mentioned.

The blending amount of these water repellents is not strictly limited and can be varied over a wide range, but the water repellent is generally used within the range of 1 to 10 parts by weight per 1 part by weight of the deodorant component. Appropriate.

Examples of the resin processing agent to be used include glyoxal resin, ethylene urea resin, melamine resin, urea resin, epoxy resin, acrylic ester resin and the like.

The compounding ratio of these resin finishing agents can be appropriately changed over a wide range according to the type of deodorant component and the purpose of use of the deodorant processed fiber product of the present invention, but the resin agent is generally added to 1 part by weight of the deodorant component. On the other hand, it is preferably used in the range of 5 to 20 parts by weight.

Furthermore, zinc borofluoride as a reaction accelerator for the resin processing agent,
Organic amine salts, metal salts, zinc nitrate or the like can be used alone or as a mixed catalyst.

The amount of catalyst used is 10 to 30 with respect to 100 parts by weight of the resin processing agent.
A range of parts by weight is preferred.

The liquid medium that can be used includes water or a mixture of water and a small amount of alcohol (eg, ethanol).

Further, in order to enhance the solubility of the deodorant component in these liquid media, a surfactant, especially a nonionic surfactant can be added to the liquid media.

Further, a softening agent such as a fatty acid ester higher alcohol sulfate may be appropriately added in order to impart desired properties to the fiber product.

As the fibers, natural fibers such as cotton and hemp, or regenerated fiber fibers such as viscose rayon and cupra, or a combination of these natural fibers or regenerated fibers and synthetic fibers such as polyester, nylon, polyacrylonitrile fiber, etc. It may be a blended product or a mixed fabric.

In the method of the present invention, after the deodorant component is attached to the fiber together with the mixture of the cellulose-reactive water repellent and the resin finishing agent,
