Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has durability for raw cotton, raw yarn, woven fabric, knitted fabric, non-woven fabric or a fiber product made of these, which is made of at least one kind of synthetic fiber, natural fiber and recycled fiber. The present invention relates to a novel deodorant processing composition for imparting deodorant function and flexibility.

[0002]

2. Description of the Related Art Hitherto, many deodorizing treatments have been proposed so far, in which natural or synthetic fibers are coated or sprayed with a compound having deodorant properties, or the compound solution is impregnated with fibers. For example, a method of using a deodorant substance taken out from a plant of theaceae family (Japanese Patent Publication No. 2-44950 and Japanese Patent Publication No. 2-44951) is described. However, since the deodorant is merely contained or attached, it often drops during use, and there is a problem in the durability of the deodorant effect such as washing resistance.

Therefore, a method of directly supporting the deodorant on the fiber has been proposed. For example, decomposition of malodorous substances by porphyrin-type and flavone-type metal complexes having redox ability (Japanese Patent Publication No. 2-13064 and Japanese Patent Publication No. 2-44952).
No. gazette). However, when the metal complex is supported on the fiber as a catalyst, it has a drawback that it is not possible to avoid the characteristic coloring due to the metal. Iron phthalocyanine becomes green, and cobalt phthalocyanine has a drawback that it develops blue.

Further, a method of graft-polymerizing a monomer having a carboxyl group on the fiber surface (Japanese Patent Laid-Open No. 62-142).
562 and JP-A-6-184941) have been proposed. This processing method is effective only for basic malodors such as ammonia among the three major malodors, is not effective for malodors such as mercaptans and acidic malodors such as acetic acid, and the processing conditions are complicated and the fiber texture is not affected. It has a drawback of being damaged. The present inventors have completed the present invention as a result of earnest research to improve the above drawbacks.

[0005]

The object of the present invention is to fabricate raw cotton, raw yarn, woven fabric, knitted fabric, non-woven fabric or a fiber product composed of these, which is made of at least one kind of synthetic fiber, natural fiber and recycled fiber. However, a novel deodorant processing composition for industrially providing a deodorant function and flexibility that is effective and durable against the bad odor of ammonia, amines, hydrogen sulfide, mercaptans, and lower fatty acids It is to provide it easily and cheaply.

[0006]

The present invention has the following constitution in order to achieve the above object. That is, the present invention provides (A)
A deodorant processing composition comprising a metal silicate or metal aluminosilicate having an average particle diameter of 10 μm or less, (B) a softening agent, and (C) a binder which is a polymer compound.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The composition of the present invention comprises ordinary synthetic fibers such as acrylic synthetic fibers, polyester and nylon.
It is directly processed into fibers, such as cotton, rayon, and wool, and fiber products, to impart a durable deodorant function and flexibility.

The deodorant (A) is a metal salt of silicate or a metal salt of aluminosilicate, which is a component expressed as an oxide of SiO ₂ · MO _{n / 2} or SiO ₂ · MO _{n / 2} · Al.
₂ O ₃ (M is zinc, copper, silver, cobalt, nickel, iron,
It is a powder containing as an active ingredient a silicate metal salt or an aluminosilicate metal salt corresponding to at least one metal selected from titanium, barium, tin, magnesium or zirconium, and n represents the valence of the metal.

The amphoteric processed product has the characteristics of a solid acid and a solid base, and each of them exists individually without contact, and in addition, a structure in which acidic SiO ₂ and a basic metal oxide are bonded to each other. It has an ion-exchange property with basic malodors such as ammonia and amines and acidic malodors of lower fatty acids. Further, since it has a porous structure, it has a large surface area and is expected to exhibit deodorant properties due to the adsorption action. Although the mechanism for deodorizing the bad odors of hydrogen sulfide and mercaptans is not clear, it is considered to be due to the oxidation catalytic action of metal silicates and metal aluminum silicates.

The above deodorant is used as a white to light colored powder, and the particle size is 10 μm or less, preferably 5 μm or less. If the particle size exceeds 10 μm, the workability deteriorates and the texture is impaired. As the deodorant, other deodorants may be impregnated and used together.

The deodorant can be produced by a generally known method, for example, a water-soluble silicate, a water-soluble metal salt or a water-soluble aluminum salt and / or a water-soluble aluminate, etc. It is produced by reacting in the presence and heating if necessary. This reaction is precipitated by metathesis. That is, an alkali silicate such as sodium silicate is used as the silica component, a sulfate, chloride, or a water-soluble metal salt such as nitrate is used as the metal oxide component, and when using an alumina component, sodium aluminate and / Or a water-soluble aluminum salt such as aluminum sulfate or aluminum chloride is used and mixed in the presence of water to cause a metathesis reaction. In order to carry out the metathesis reaction homogeneously, the reaction is carried out while simultaneously pouring an aqueous solution of seiic acid, an aqueous solution of a metal salt, or an aqueous solution further containing an alumina component into water in which silica is dispersed in advance. The silicic acid metal salt or the aluminosilicate metal salt obtained by this method exhibits excellent deodorant properties.

Softener (B) used in combination with the above deodorant (A)
Is generally used and includes the following (1) to (7). (1) A fatty acid amide composed of a fatty acid and a polyalkylene polyamine or an alkanol amine is added to a polyoxyalkylene alkyl ether, a polyoxyalkylene alkyl phenyl ether, a higher alcohol sulfate ester salt,
Emulsified and dispersed in water with an emulsifier such as polyoxyalkylene alkyl ether sulfate and alkyl sulfonate. (2) Quaternary ammonium salts such as monostearyl trimethylammonium chloride and distearyldimethylammonium chloride (3) Liquid paraffin, mineral oil such as spindle oil, ester synthetic oil such as methyl oleate and dioctyl sebacate, and polysiloxane A derivative obtained by emulsifying and dispersing a derivative in water with the above emulsifier. (4) A higher alcohol obtained by emulsifying and dispersing in water with the above-mentioned emulsifier. (5) A product obtained by emulsifying and dispersing a polyhydric alcohol fatty acid ester in water with the above emulsifier. (6) Water dispersion of unsaturated higher alcohol sulfate ester salt. (7) Unsaturated higher fatty acid triglyceride and / or higher fatty acid mono-diglyceride mixture sulfate ester salt water-dispersed. These softeners (1) to (7) are effective not only for imparting flexibility and smoothness but also for improving the dispersibility of the antibacterial agent when used in combination.

The binder (C) used in combination with the deodorant (A) is a generally used polymer compound and includes the following (1) to (6). (1) A polyurethane derivative composed of an aliphatic polyisocyanate and a polyalkylene glycol. (2) An acrylic resin made of a polymer of acrylic acid, methacrylic acid and their esters. (3) Vinyl acetate resin, styrene-butadiene resin. (4) Polysiloxane derivatives capable of polymerizing or condensing vinyl group-containing diorganosiloxane, methylhydrogenpolysiloxane, hydrogen-capped dimethylpolysiloxane at both ends, and the like. (5) An epoxy resin which is a condensate of polyphenols such as bisphenol A and epichlorohydrin. (6) Formalin resins such as melamine formaldehyde resin and urea formaldehyde resin or glyoxal resins. These binders (1) to (6) are effective not only for providing washing resistance but also for improving the dispersion stability of the antibacterial agent when used in combination. Although a resin solution can be used as the binder, workability and finish are particularly good when an aqueous emulsion is used.

The deodorant (A), the softener (B) and the binder (C) are used by uniformly dispersing and mixing with a homomixer or the like. The ratio of each is 5 to 50 g / l of the deodorant (A),
Softener (B) 5 to 50 g / liter, binder (C)
It is 5 to 50 g / liter, and the deodorant finishing agent is applied to the fiber or the textile product by a usual method.

In the padding method, the fibers are dipped in the liquid of the deodorant finishing agent for a short time, immediately squeezed with a dehydrating mangle to dry and cure. The adhesion is controlled by the concentration of the processing agent in the liquid and the dehydration rate. In the spray method, fibers are placed on a conveyor at a constant speed, and then a deodorant finishing agent is sprayed on a fixed amount, dried and cured. Used when the dehydrated mangle cannot be used depending on the material. For example, carpets, car seats, etc. In the exhaust method, a dilute liquid of the processing agent is used, and the conditions such as temperature, immersion time, and the number of liquid circulations are set, and the processing agent is selectively adsorbed on the fibers, dried, and cured. Generally, a dyeing machine is used. Of these methods, the padding method is suitable.

The amount of the deodorant attached is 0.4 to 7% by weight, preferably 1 to 5% by weight, based on the fiber. If it is less than 0.4% by weight, sufficient deodorant properties cannot be obtained. If it is 7% by weight or more, the texture is impaired.
