Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an antibacterial garment made of polyester filaments and, more particularly, to an antibacterial garment having low dust generation and antistatic properties and excellent washing durability. The present invention relates to an antibacterial garment for antibacterial clothing comprising:

[0002]

2. Description of the Related Art In recent years, due to the development of the electronics industry, precision equipment, pharmaceuticals, medical equipment, food processing and medical technology, fine dust and bacteria and static electricity at manufacturing sites and medical sites have become obstacles. Is being cleaned up. As part of this, the development of dust-proof garments, dust-free garments, and sterile garments that can be used in a clean environment is being promoted. Generally, woven fabrics for dustproof garments, dustless garments, and sterile garments (hereinafter collectively referred to as "dustproof garments") include form stability, mechanical strength, chemical resistance,
Polyester fibers are mainly used because of their excellent heat resistance and washing durability. However, polyester fibers have low moisture absorption, so if they are worn for a long time, they tend to cause stuffiness or stickiness due to perspiration, and if they are worn continuously for several days, the bacteria that survive in the sweat will grow However, there is a problem that sweat odor is generated and wearing comfort is reduced. As anti-odor measures, various methods of imparting antibacterial properties have been studied.

There are two methods for imparting antibacterial properties to fibers: a method of kneading an inorganic antibacterial agent such as silver, copper or zinc in the step of spinning a polyester, and a method of spraying or padding an organic antibacterial agent such as a quaternary ammonium salt. Methods of treating and applying to fibers have been employed. The former case is excellent in terms of washing durability and low dust generation, but cannot be processed into products such as cloth. In addition, since the antibacterial agent precipitates as crystals on the spinneret during spinning, there are problems with productivity such as thread breakage and fusion.In addition, the antibacterial agent is uniformly dispersed in the fiber, so ensuring performance is important. It is necessary to knead a large amount of antibacterial agent,
There is a problem of high cost.

[0004] On the other hand, in the latter case, although there is an advantage that antibacterial processing can be applied to products such as cloth, antibacterial washing durability is inferior, and there is a problem of dust generation due to dropout of antibacterial agents and binders. Neither method is applicable to dustproof clothing fabrics.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to improve the antistatic property and washing durability of a conventional polyester fabric for a dustproof garment while maintaining the morphological stability, strength retention and low dust generation. An object of the present invention is to provide an antibacterial dustproof garment fabric having excellent antibacterial properties.

[0006]

[MEANS FOR SOLVING THE PROBLEMS]
One aspect of the antibacterial dustproof garment fabric is that the conductive fibers are warp.
And / or fibers arranged in weft yarns per gram of fabric.
Surface area of 0.12m ^TwoPolyester filler is above
The polyester filament
Has a molecular weight of 200 to 700 and an inorganic / organic value of 0.3 to 0.3
Pyridine antibacterial agent having an average particle size of 1.4 or less and 2 μm or less
And the amount of dust generated from the woven fabric is 20 pieces / ft.^Three・ 100cm^TwoLess than
And a bacteriostatic activity value of 2.2 or more
It is a fabric for antibacterial dustproof clothing.

[0007] In another embodiment of the antibacterial dustproof woven fabric of the present invention, the conductive fibers are arranged in a warp and / or a weft,
A woven fabric containing a polyester filament having a single fiber fineness of 5 denier or less is used, and the polyester filament has a molecular weight of 200 to 700 and an inorganic / organic value of 0.3 to 0.3.
The woven fabric contains a pyridine-based antibacterial agent having an average particle diameter of 1.4 μm or less, and the woven fabric has a dust generation amount of 20 pieces / ft ³ · 100 cm ^2.
A bacteriostatic activity value of 2.2 or more.

[0008] The dustproof garment of the present invention is formed by using the above-mentioned woven fabric for antibacterial dustproof garment.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The polyester filament used in the antibacterial dust-proof garment fabric of the present invention is not particularly limited. Repeating unit 9
0 mol% or more), and those having a butylene terephthalate unit as a main repeating component (specifically, 9 of the repeating unit).
0 mol% or more). Among them, a fiber composed of a polyester having an ethylene terephthalate unit of 90 mol% or more as a repeating component is preferable, and a fiber composed of a polyester having an ethylene terephthalate unit of 95 mol% or more as a repeating component is more preferable. 1 ethylene terephthalate unit
It is more preferable that the fiber is made of a polyester (ie, polyethylene terephthalate) having a repeating component of 00 mol%. The cross-sectional form of these polyester fibers may be round or irregular.

The polyester filament used in the fabric of the present invention contains a pyridine-based antibacterial agent having a molecular weight of 200 to 700, an inorganic / organic value of 0.3 to 1.4 and an average particle size of 2 μm or less. .

[0011] Such a pyridine-based antibacterial agent firmly adheres or exhausts / diffuses to the polyester filament.
This is because the three requirements of a specific molecular weight, inorganic / organic value and average particle size are brought close to the conditions close to those of a disperse dye that exhausts and diffuses inside the fiber, thereby exhibiting the same behavior as a disperse dye. Conceivable. When these conditions are not satisfied, the antibacterial agent does not firmly adhere to the polyester filament or does not absorb or diffuse, and sufficient industrial washing durability cannot be obtained.

When the molecular weight is less than 200, the antibacterial agent adheres to, or is absorbed and diffused into, the polyester filament, but the washing durability is low. On the other hand, when the molecular weight exceeds 700, the antibacterial agent does not adhere or exhaust to the polyester filament. Preferably, the molecular weight of the antimicrobial agent is between 300 and 50
0.

Next, the “inorganic / organic value” as referred to in the present invention.
Is a value that organically treats the polarity of various organic compounds devised by Minoru Fujita [Referred to Chemical Experiments-Organic Chemistry-Kawade Shobo (1971)]. The value is obtained by determining the values of the inorganic and organic properties of various polar groups as shown in Table 1, obtaining the sum of the inorganic values and the sum of the organic values, and taking the ratio between the two.

[0014]

[Table 1]

In the organic concept, for example, the inorganic / organic value of polyethylene terephthalate is calculated to be 0.7. The present invention focuses on the affinity between a synthetic fiber and an antibacterial agent based on the value calculated based on the organic concept,
An antibacterial agent having an organic value within a predetermined range is attached or exhausted and diffused to a polyester filament.

When the inorganic / organic value is less than 0.3, the organic property becomes too strong. On the other hand, when it exceeds 1.4, the inorganic property becomes too strong. Difficult to spread. The inorganic / organic value is preferably from 0.35 to 1.3, preferably from 0.4 to 1.
More preferably, it is 2.

For example, 2,3,5,6-tetrachloro-
In the case of 4-hydroxypyridine, one benzene nucleus,-
One 4 Cl group, one -OH group, inorganic value for containing one -NR ₂ group becomes 265. Further, the organic value is 180 since it contains five C (carbon) and four -Cl groups, and the inorganic value / organic value becomes 1.47. Since 2-pyridylthiol-1-oxide zinc is present as a chelate complex and zinc and sulfur are considered to have a covalent bond in terms of electronegativity, the inorganic value of this compound is 85, and the organic value is 85. Is 190, and the inorganic value / organic value can be calculated as 0.45. On the other hand, in sodium 2-pyridylthiol-1-oxide which is the same pyridine antibacterial agent, sodium and sulfur have an electronegativity difference of 1.6 or more, and this bond becomes an ionic bond. In this case, sodium is converted into a light metal salt. Since it works, the inorganic value can be calculated to be 585 and the organic value can be calculated to be 190, and the inorganic value / organic value is 3.0, so that the affinity with the polyester is deteriorated.

In the present invention, among these antibacterial agents, those having an average particle size of 2 μm or less are used. If the average particle size exceeds 2 μm, it is difficult for the polyester filament to adhere to or be exhausted from the polyester filaments, and when formed into a working liquid, the particles tend to settle, resulting in a lack of stability of the liquid. Preferably, the average particle size of the antimicrobial agent is 1 μm or less.

As such antibacterial agents, 2-chloro-6-trichloromethylpyridine, 2-chloro-4-trichloromethyl-6-methoxypyridine, 2-chloro-4-trichloromethyl-6- (2-furylmethoxy) pyridine ,
Di (4-chlorophenyl) pyridylmethanol, 2,
Pyridine compounds such as 3,5-trichloro-4- (n-propylsulfonyl) pyridine, zinc 2-pyridylthiol-1-oxide, and di (2-pyridylthiol-1-oxide) can be used. Among them, in particular, 2-pyridylthiol-1-oxide zinc has a good affinity with the fiber, and is firmly attached to and exhausted from the fiber, so that it has good washing durability, and the target bacterial species showing an effect including MRSA. Is preferred in terms of the size of

In the present invention, the polyester filament is preferably colored. This is because a fabric having excellent washing durability can be obtained by exhausting and diffusing the antibacterial agent into the polyester filament simultaneously with the dyeing. Here, being colored means that the polyester filament is a disperse dye, an acid dye, a cationic dye,
Includes coloring such as fluorescent whitening agents.

The polyester filament used in the present invention has a fiber surface area of 0.12 m ² or more or a single fiber fineness of 5 denier or less per gram of woven fabric, and preferably has a surface area of 0.15 m ² or more or a single fiber fineness of 5 g or less. 4
It is less than denier. Since the action of the antibacterial agent adhering to or exhausting from the fiber depends on the surface area of the fiber or the fineness of the single fiber of the fiber, a fiber having a surface area of 0.12 m ² or more or a fiber having a single fiber fineness of 5 denier or less is highly industrialized. An antibacterial fiber structure having washing durability can be obtained. The same effect can be obtained even when a plurality of types of synthetic fibers or further natural fibers are combined.

When antibacterial properties are taken into consideration, the state in which the antibacterial agent is attached to the fiber surface is most excellent because the frequency of contact with bacteria is high. However, in this state, the antibacterial agent is easily peeled, which is not preferable from the viewpoint of washing durability. On the other hand, when the antibacterial agent is uniformly diffused into the fiber, the antibacterial property is reduced, but the washing durability is improved. From the above, the state in which the antimicrobial agent is distributed in a ring shape in the vicinity of the fiber surface inside the fiber or branched and diffused from the fiber surface to the inside in the form of a branch is the antibacterial property, washing durability and low dust generation property. It is considered excellent.

The state in which the antibacterial agent is distributed in a ring shape near the fiber surface inside the polyester filament is as follows.
X-ray microanalyzer (EMAX-2 manufactured by Horiba, Ltd.)
000) to analyze the fiber cross-section, paying attention to specific elements contained in the antibacterial agent, for example, sulfur, etc.
By evaluating the distribution of the antimicrobial agent inside the polyester filament, the element is present near the fiber surface inside the fiber, and the distribution becomes a ring shape with a predetermined width when viewed from the fiber cross section. It can be confirmed from that.

The state in which the antibacterial agent is branched and diffused from the fiber surface into the inside of the polyester filament in a branch shape can be confirmed by observation with a scanning electron microscope (SEM).

In the present invention, by changing the processing conditions of the fiber structure, the antibacterial agent is attached to the fiber surface, distributed in a ring shape from the fiber surface toward the inside, or branched into the fiber inside. It can be controlled to be in a branched and diffused state.

In the woven fabric used in the present invention, the conductive fibers are arranged in a warp or a weft, or in both a warp and a weft. By arranging the conductive fibers in this way, it is possible to prevent the fabric from being charged with static electricity.
The conductive fiber referred to here is a composite form of a conductive component as long as the conductive fiber has a performance of about 1 × 10 ⁶ Ω · cm in a surface leakage resistance measurement method described in reference to JIS 1094 method. The cross-sectional shape is not limited. As the conductive component, metal oxide, carbon, ceramic, or the like can be used.

The woven fabric of the present invention has a bacteriostatic activity value of 2.2 or more according to the bacteriostatic evaluation method (unified test method) defined by the SEK (Council for Evaluation of New Function of Textile Products). If the bacteriostatic activity value is less than 2.2, the desired bacteriostatic effect cannot be obtained.

Further, it is preferable that the bacteriostatic activity value of the woven fabric of the present invention after washing 50 times is 2.2 or more. Here, "one wash" is based on JIS 1042 F-2 method,

Wash at 2 ° C, bath ratio 1:20 for 15 minutes, then drain,

The woven fabric of the present invention is a woven fabric using polyester filament yarns.
It is not particularly limited as long as it is a structure usually used as a woven fabric for dustproof clothing, such as a twill structure, a satin structure, and a change structure thereof.

The woven fabric of the present invention is composed of polyester filaments, and the woven density of the warp and the weft is preferably 50 to 250 yarns / inch.
More preferably, it is 250 pieces / inch. If the weaving density of the warp and weft of the woven fabric is less than 50 yarns / inch,
There is a tendency that seam misalignment or eye misalignment during wearing tends to occur. On the other hand, if the woven fabric density of the warp and the weft exceeds 250 yarns / inch, the woven fabric for a dust-proof garment becomes thick and coarse, and the lightness tends to be impaired.

It is preferable to use polyester filaments having a single fiber fineness of 0.5 to 5 denier as the polyester filaments used for the warp and the weft. If at least one of the warp yarn and the weft yarn has a single fiber fineness of more than 5 denier, the texture of the fabric becomes hard and the dust resistance tends to decrease. Further, when it is less than 0.5 denier, fluff is easily generated due to friction at the time of wearing, which causes dust. In addition, the warp and the weft preferably have a single fiber fineness of 0.5 denier or more from the viewpoint of weaving properties and woven fabric strength. From the viewpoint of producing a soft and tight woven fabric, a mixed fiber of different fineness filament yarns having different single fiber fineness may be used.
In this case, the total surface area of the mixed filament yarn is 0.12 m
^The number is preferably ² or more, and it is possible to produce an antibacterial and tight dustproof clothing fabric.

It is preferable to use polyester filaments having a total fineness of 50 to 350 denier for the warp and weft. If the total fineness of at least one of the warp and the weft is less than 50 denier,
It tends to be a thin, dust-free garment fabric without tension. Also,
If the total fineness is greater than 350 denier, the fabric becomes a thick fabric, and at the same time, the texture is hard, and it becomes difficult to use it as a fabric for dustproof clothing.

Further, it is preferable that the conductive fibers are disposed at an interval of 2 to 10 mm for the warp or the weft, or for both the warp and the weft. This conductive fiber is 2 to 8 m
It is more preferable to arrange at intervals of m, and it is even more preferable to arrange at intervals of 2 to 5 mm.

The method for producing the antibacterial dustproof garment fabric of the present invention will be described below.

The woven fabric for dustproof clothing is immersed in a liquid containing the above-mentioned antibacterial agent using a liquid dyeing machine or the like.
C. for 10 to 120 minutes, more preferably 120 to 135
It can be manufactured by performing a heat treatment at 20 ° C. for 20 to 60 minutes. At this time, a disperse dye and, if necessary, a dispersible fluorescent whitening agent may be added to the liquid. Under heating conditions of less than 90 ° C., the antibacterial agent does not adhere or exhaust to the polyester fiber. On the other hand, when the temperature exceeds 160 ° C., the effect corresponding to the energy consumption cannot be obtained, and the cost performance deteriorates.

The dyeing of the woven fabric may be carried out in the usual steps of relaxation scouring, intermediate setting, dyeing and finishing setting.

In this method, it is preferable to perform a dry heat treatment at 160 to 200 ° C. for 15 seconds to 5 minutes, more preferably at 170 to 190 ° C. for 30 seconds to 2 minutes after the in-liquid treatment. Due to such dry heat treatment, the antimicrobial agent diffuses in from the polyester fiber surface and is distributed in a ring shape near the fiber surface inside the fiber, or exists in a state branched and diffused from the fiber surface to the inside in a branch shape. It is possible to improve the washing durability without impairing the antibacterial property and suppress dust generation. Under the heating condition of less than 160 ° C., the effect of the dry heat treatment is not obtained. Also, 20
Conditions exceeding 0 ° C. are not preferable because yellowing and embrittlement of the polyester fiber, sublimation or thermal decomposition of the dye or antibacterial agent, and increase in energy consumption occur. By changing the treatment conditions, the antimicrobial agent can be controlled to each state of adhesion to the fiber surface, ring-shaped distribution inside the fiber, and diffusion inside the fiber.

The antibacterial dustproof garment fabric according to the present invention can be used as an antibacterial dustproof garment having low dust generation and antistatic properties and excellent washing durability and, in particular, electronic parts. It is most suitable as a dust proof garment used for worker clothing in manufacturing processes of electronic equipment, precision equipment, medicine, medical equipment, and food.
