DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is excellent in durability and has good deodorizing performance against ammonia, amines, hydrogen sulfide, mercaptans, acetic acid, etc., which are representative of malodors generated in daily life. The present invention relates to a spun yarn, a batting and a fiber product containing an acrylic synthetic fiber having excellent antibacterial properties against Staphylococcus aureus, Klebsiella pneumoniae and the like.

[0002]

2. Description of the Related Art Acrylic synthetic fibers are widely used for clothing, bedding, and interiors. In recent years, napped products such as blankets, moquettes, mats, and carpets, as well as knitted fabrics such as socks, underwear, sheets, and futons. There are strong demands for various products such as batting, insoles, filters such as stuffed animals, stuffed animals, cushions, etc. which have deodorant and antibacterial properties. As a method for imparting a function of eliminating odors, which has been regarded as a bad odor, to fibers and textile products, a method of grafting a vinyl monomer having an acidic group to fibers (Japanese Patent Publication No. 3-77308, Japanese Patent Publication No. JP-A-58392, JP-A-62-142562, etc.), copper compounds (JP-A-61-231202, JP-A-62-69)
No. 78, etc.) and various deodorants (JP-A-61-2580).
No. 76, JP-A-56-100060, etc.) are attached to the fiber surface. Examples of a method for introducing a vinyl monomer having a deodorizing function into fibers include a method in which a vinyl monomer having an acidic group is copolymerized and the polymer is converted into a fiber.

[0003] Among these methods, however, in the grafting, the texture of the fiber changes, the uniform reaction efficiency cannot be obtained, the deodorizing effect cannot be sufficiently exerted, and the grafting reaction similar to the dyeing process is performed. It must be performed, and the number of processes increases, and at that time, problems such as contamination of a processing machine and wastewater by a processing liquid occur.

[0004] In the post-treatment process of attaching fine powder having a deodorizing effect to the fiber surface and the post-processing process of infiltrating, applying, and spraying a solution having a deodorizing effect on fiber products, the unique texture of the fiber decreases, There are drawbacks such as the agent falling off due to washing with water and dry cleaning, resulting in insufficient washing durability.

As a method for introducing a vinyl monomer having a deodorizing function into a fiber, there is a method in which a vinyl monomer having an acidic group is copolymerized during polymerization to produce a fiber of the polymer. Since there are more vinyl monomers having an effective acid group inside the fiber than on the fiber surface, the rate of direct contact with bad odors is small compared to the introduction rate of the vinyl monomer having an acidic group, and the deodorizing effect is insufficient. However, there are drawbacks such as a decrease in fiber material and a deterioration in texture.

Most of these processing methods are effective only for basic odors such as amines and ammonia, acidic odors such as acetic acid, or malodors such as hydrogen sulfide and mercaptans. Almost no odor is known which effectively acts on both odors and all odors such as hydrogen sulfide and mercaptans and is industrially safe and inexpensive for producing fibers.

For imparting antibacterial properties, there is a method similar to the above-mentioned method for imparting the function of eliminating odor to textiles. For example, methods of applying and spraying a compound having antibacterial properties to textile products, methods of impregnating fibers and fiber products with a solution of compound having antibacterial properties, and resin processing using a compound having antibacterial properties and a resin are well known. Have been. However, these methods have the drawback that their efficacy is not persistent and that the attached compound is easily dropped off by washing or the like, and that the unique texture of the fiber is impaired.

[0008] So far, as an antibacterial fiber,
Add fine metal powder to the copolymer containing acrylonitrile,
A method of spinning (JP-A-55-115440 and the like) or a method of adding an azole derivative and spinning (JP-A-53-115440)
No. 139895) has been proposed, but in general, the antibacterial property and the deodorant property are separately provided, and a fiber having both antibacterial property and deodorant property and a fiber product thereof are used. almost none.

[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.
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, methyl methacrylate, alkyl methacrylate such as ethyl methacrylate, styrene, vinyl acetate, vinyl chloride, vinylidene chloride, vinyl ethyl ether, methacrylonitrile, etc. Neutral monomers, acrylic acid, methacrylic acid, allylsulfonic acid, methallylsulfonic acid, styrenesulfonic acid, acidic monomers such as 2-acrylamido-2-methylpropanesulfonic acid and ammonium salts of these monomers, One obtained by copolymerizing an appropriate combination of alkali metal salts and the like at a ratio of 60% by weight or less is exemplified. The acrylonitrile-based polymer may be produced by any method such as suspension polymerization, solution polymerization, and emulsion polymerization.

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

The average particle size of the fine metal silicate or aluminosilicate metal powder used in the present invention depends on the particle size distribution, but is 10 μm or less, preferably 0.5 to 10 μm or less, more preferably 1 to 10 μm. 7 μm. If the average particle size of the fine powder is less than 0.5 μm, aggregation tends to occur, and uniform dispersion is difficult unless a special dispersing device or dispersant is used.
On the other hand, if the average particle size of the fine powder exceeds 10 μm, the spinning filtration pressure will increase, and yarn breakage will occur frequently.

The fine powder of the metal silicate or the 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 the BET specific surface area is lower than 100 m ² / g, the contact efficiency with malodors decreases, and sufficient deodorizing ability cannot be exhibited.

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

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

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

In the present invention, the dispersion concentration of the organic solvent in the fine powder of the metal silicate or the 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, when the content exceeds 40% by weight, a good dispersion state cannot be obtained, and it becomes difficult to produce easily industrially.

The obtained spinning dope is spun out from an ordinary spinneret. As for 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 ordinary acrylic synthetic fibers. It is optional to add titanium oxide, a twist-resistant agent, a light-proofing agent, a heat storage agent, and the like which are usually used within a range that does not impair the characteristics of the present invention.
Additives may be used when producing fine powders containing a metal silicate or aluminosilicate as an active ingredient within a range that does not impair the properties of the present invention, and additives may be added to improve the dispersibility of the fine powder. Use is optional.

The spun yarn and the batting of the present invention are characterized in that they contain the above-mentioned acrylic synthetic fibers having novel and 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, depending on the amount of the fine metal silicate or aluminosilicate metal powder added.

[0022] The fiber product of the present invention is also characterized in that it contains the above-mentioned acrylic synthetic fiber having the novel 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, depending on the amount of the fine metal silicate or metal aluminosilicate powder added.

The fiber to be blended is a synthetic fiber such as an acrylic fiber, a polyester fiber or a nylon fiber, or a natural fiber such as cotton, wool or hemp. The batting of the present invention is characterized by being used inside futons, cushions, stuffed animals and the like, and can be manufactured by a known processing technique. The textile product of the present invention is made of at least one selected from the group consisting of blankets, carpets, mats, nap products such as high piles, sheets, sweaters, jerseys, socks, knitted fabrics such as underwear, insoles, and filters. It is a characteristic fiber product and can be manufactured by known processing techniques (cross knitting, cross weaving, non-woven fabric).

The above spinning stock solution is spun into a 58% DMF aqueous solution at 22 ° C., stretched while removing the solvent, and washed with water.
Drying and dry densification were performed by applying an oil agent. After passing through each step of stretching, shrinking and crimping,
A moist heat treatment was performed at a temperature of ° C. Judgment of the spinning operability results of the obtained fibers was made based on the results of filtration pressure, single yarn breakage, roller wrapping, yield to fiber, etc., when the fibers were manufactured under the conditions described in the examples.

Blended cotton was mixed at the ratios shown in Table 1 and ordinary cotton spinning was performed thereafter to obtain a spun yarn of 40 / l count. Next, using a circular knitting machine having a diameter of 11 inches and 22 G, a green fabric of a milling structure was formed, and scouring, bleaching, drying, finishing, and setting were sequentially performed to prepare a circular knit.

In Comparative Examples 1 and 2, the fine powder used in Examples 1 to 7 was added to the acrylonitrile copolymer at a ratio out of the range. In Comparative Example 3, the blending ratio was out of the range.
Therefore, each step was performed in the same manner as in the example. Tables 1 and 2 summarize the above results.

As is clear from the comparative examples in Tables 1 and 2, it can be seen that the product of the example has excellent deodorizing performance and antibacterial performance as compared with the product of the comparative example. In the case of Comparative Example 1 in which the fine powder was added at 0.2% to the acrylonitrile-based polymer, spinning operability and fiber quality were good, but sufficient deodorizing performance and antibacterial performance were not obtained. In addition, the fine powder
In the case of Comparative Example 2 in which 5% was added, the spinning operability such as an increase in spinneret filtration pressure and breakage of single yarn was poor, and no fiber could be obtained. In Comparative Example 3, sufficient deodorant performance and antibacterial performance were not obtained because the blending ratio was out of the range.
