Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention has excellent durability and good deodorizing performance against ammonia, amines, hydrogen sulfide, mercaptans, acetic acid, etc., which are typical offensive odors in daily life. The present invention also relates to a spun yarn, batting, and a fiber product containing an acrylic synthetic fiber having excellent antibacterial properties against Staphylococcus aureus, Klebsiella pneumoniae, and the like.

2. Description of the Related Art Acrylic synthetic fibers have been widely used for clothing, bedding and interiors, but in recent years blankets, moquettes, mats, napped products such as carpets, knitted fabrics such as socks, underwear and sheets, and futons. There has been a strong demand for various products such as stuffed animals, paddings such as cushions, insoles, filters, etc. that have deodorant and antibacterial properties. Conventionally, as a method for imparting a function of eliminating an odor, which has been regarded as a bad odor, to a fiber and a fiber product, a grafting process of a vinyl monomer having an acidic group onto the fiber (Japanese Patent Publication No. 3-77308, Japanese Patent Publication No. 2308/1990). -58392, JP-A-62-142562, etc.), copper compounds (JP-A-61-231202, JP-A-62-69)
No. 78) and various deodorants (JP-A-61-2580).
No. 76, JP-A-56-100060, etc.) is known to be attached to the fiber surface. As a method of introducing a vinyl monomer having a deodorizing function into the fiber, a method of copolymerizing a vinyl monomer having an acidic group and making the polymer into a fiber can be mentioned.

However, among these methods, the grafting process causes a change in the texture of the fibers, a uniform reaction efficiency cannot be obtained, and the deodorizing effect cannot be sufficiently exerted, and a grafting reaction similar to the dyeing step is performed. This has to be carried out, which causes problems such as an increase in the number of steps and contamination of the processing machine and drainage due to the processing liquid at that time.

In the post-treatment process of adhering fine powder having a deodorizing effect to the fiber surface and the post-treatment process of infiltrating, coating and spraying a solution having a deodorizing effect on the textile product, the texture unique to the fiber is deteriorated, There are drawbacks such as lack of washing durability due to loss of agent by washing with water or dry cleaning.

Further, as a method of introducing a vinyl monomer having a deodorizing function into fibers, there is a method of copolymerizing a vinyl monomer having an acidic group at the time of polymerization to make the polymer into a fiber. Since more vinyl monomers with acidic groups that are effective exist inside the fiber than on the fiber surface, the rate of direct contact with bad odors is small relative to the introduction rate of vinyl monomers with acidic groups, and the deodorizing effect is insufficient. However, there were drawbacks such as deterioration of fiber material and deterioration of texture.

Most of these processing methods are effective only for basic malodors such as amines and ammonia, acidic malodors such as acetic acid, or malodors such as hydrogen sulfide and mercaptans. Little is known that effectively acts on both malodors and all odors such as hydrogen sulfide and mercaptans and can be industrially used safely and inexpensively for producing fibers.

There is a method for imparting antibacterial properties, which is similar to the method for imparting the odor eliminating function to the textile product as described above. For example, well-known methods include coating and spraying an antibacterial compound on a textile product, impregnating a fiber and a textile product into an antibacterial compound solution, and resin processing using a compound and an antibacterial compound in combination. Has been. However, these methods have the drawbacks that the efficacy is not sustainable and that the attached compound is easily dropped off by washing or the like, and the texture unique to the fiber is impaired.

So far, as fibers having antibacterial properties,

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the present invention will be described in detail. The acrylic synthetic fiber used in the present invention is at least 40% by weight.
It is made of an acrylonitrile-based polymer containing acrylonitrile, and any other copolymerizable monomer can be used together. For example, methyl acrylate, alkyl acrylate such as ethyl acrylate, methacrylic acid alkyl ester such as methyl methacrylate, ethyl methacrylate, styrene, vinyl acetate, vinyl chloride, vinylidene chloride, vinyl ethyl ether, methacrylonitrile, etc. Neutral monomers, acidic monomers such as acrylic acid, methacrylic acid, allyl sulfonic acid, methallyl sulfonic acid, styrene sulfonic acid, 2-acrylamido-2-methylpropane sulfonic acid and ammonium salts of these monomers, Examples thereof include those obtained by copolymerizing appropriate combinations of alkali metal salts and the like at a ratio of 60% by weight or less. The acrylonitrile polymer may be produced by any method such as suspension polymerization, solution polymerization, emulsion polymerization and the like.

[0013] As the fine powder used in the present invention, SiO 3 component composition ratios expressed as oxides _2: 5 to 80 mol% MO _n / 2: 5 to 65 mol% Al ₂ O _3: 0 to 60 mol % (M represents at least one metal selected from zinc, copper, silver, cobalt, nickel, iron, titanium, barium, tin, magnesium or zirconium, and n represents the valence of the metal) Alternatively, a metal salt of aluminosilicate is used as an active ingredient. Such metal salts are
The crystals have both solid acid and solid base properties, and exist independently on the surface of one solid particle without neutralizing each other and form an amphoteric adsorption surface. It has an excellent deodorizing effect on the acidic malodor due to the chemical adsorption action, has a large specific surface area, is excellent in the contact efficiency with the malodor, and also has a physical adsorption action, so it is considered that the deodorant can be effectively performed. Although the antibacterial property is not clear, it is considered to be based on the metal ions retained in at least a part of the fine powder.

The average particle size of the fine powder of the metal silicate or the metal aluminosilicate used in the present invention depends on the particle size distribution, but it is 10 μm or less, preferably 0.5 to 10 μm or less, more preferably 1 to It is 7 μm. If the average particle size of the fine powder is less than 0.5 μm, agglomeration easily occurs, and uniform dispersion is difficult unless a special dispersing device or dispersant is used.
Further, if the average particle diameter of the fine powder exceeds 10 μm, the spinning filtration pressure will increase and the yarn breakage will occur frequently, which is not preferable in operation.

The fine powder of metal silicate or metal aluminosilicate used in the present invention has a BET specific surface area of 100 m ^2.
/ G or more, and particularly preferably 150 m ² / g or more. If this BET specific surface area is lower than 100 m ² / g, the efficiency of contact with bad odors is lowered, and sufficient deodorizing ability cannot be exhibited.

The amount of the fine powder of metal silicate or metal aluminosilicate used in the present invention is 1 to 20% by weight based on the acrylonitrile polymer. When the content of the fine powder is less than 1% by weight, sufficient deodorant performance cannot be imparted, and when it exceeds 20% by weight, the fiber performance is deteriorated and the spinnability and spinnability in spinning are deteriorated.

As the solvent used in the present invention, any solvent may be used as long as it can dissolve the acrylonitrile polymer. For example, dimethylformamide (hereinafter DM
Examples of organic solvents such as F), dimethylacetamide, dimethylsulfoxide, and acetone are preferable in terms of solubility, solvent recovery, and handling.

As a method for adding and mixing a fine powder of a metal silicate or a metal aluminosilicate to the acrylonitrile polymer, a spinning stock solution prepared by dissolving the acrylonitrile polymer in an organic solvent is added to the metal silicate or aluminosilicate. A solution prepared by dispersing and dissolving a fine powder of an acid metal salt in an organic solvent may be added and mixed immediately before spinning. A method of dispersing and dissolving a fine powder of a silicic acid metal salt or an aluminosilicate metal salt used in the present invention in an organic solvent, and adding the prepared solution to a spinning dope containing an acrylonitrile polymer, and a method of mixing are usually Can be mixed well with the mixer.

In the present invention, the dispersion concentration of the organic solvent in the fine powder of metal silicate or metal aluminosilicate is 5 to 40.
% By weight. If the concentration is less than 5% by weight, the concentration of the spinning dope decreases, and the spinnability decreases and the fiber properties decrease. On the other hand, if it exceeds 40% by weight, a good dispersed state cannot be obtained, and it becomes difficult to industrially manufacture the composition.

The obtained spinning dope is spun out from a usual spinneret. As the spinning method, any known wet, dry-wet, and dry spinning methods can be applied, and the spinning may be performed under the same conditions as for ordinary acrylic synthetic fibers. Further, it is optional to add titanium oxide, a twisting agent, a light-proofing agent, a heat storage agent, etc., which are usually used within a range that does not impair the characteristics of the present invention.
Using an additive when producing a fine powder having a metal silicate or aluminosilicate metal salt as an active ingredient in a range that does not impair the characteristics of the present invention, and an additive for improving the dispersibility of the fine powder. It is optional to use.

The spun yarn and batting of the present invention are characteristic in that they contain the above-mentioned novel acrylic synthetic fiber having excellent performance. Such acrylic synthetic fibers are preferably used at least 10% by weight, more preferably at least 15% by weight. If it is less than 10% by weight, the deodorizing performance and the antibacterial performance are insufficient, although it depends on the addition amount of the fine powder of the metal silicate or the metal aluminosilicate.

The fiber product of the present invention is also characteristic in that it contains the above-mentioned novel acrylic synthetic fiber having excellent performance. Such acrylic synthetic fibers are preferably used at least 10% by weight, more preferably at least 15% by weight. If it is less than 10% by weight, the deodorizing performance and the antibacterial performance are insufficient, although it depends on the addition amount of the fine powder of the metal silicate or the metal aluminosilicate.

The fibers to be mixed-spun are synthetic fibers such as acrylic fibers, polyester fibers and nylon fibers, or natural fibers such as cotton, wool and hemp. The batting of the present invention is characterized by being used inside a futon, cushion, stuffed animal, etc., and can be manufactured by a known processing technique. The textile product of the present invention comprises at least one selected from the group consisting of blankets, carpets, mats, napped products such as high piles, sheets, sweaters, jerseys, socks, knitted fabrics such as underwear, and insoles and filters. It is a characteristic fiber product and can be manufactured by a known processing technique (cross knitting, cross woven, non-woven fabric).
