Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to stockings, and particularly to stockings in which at least a portion of the stockings has antibacterial properties or the like.

[Prior Art and its Problems] In recent years, stockings with antibacterial properties have been developed in order to increase the added value of stockings.

Here, in order to impart antibacterial properties to stockings, conventionally, the stockings are usually knitted using woolly nylon, etc., and then the stockings knitted in this way are dyed, and then the stockings are subjected to a softening process. During the process, the stockings were softened by adding various antibacterial agents, which allowed the antibacterial agents to adhere to the stockings and give them antibacterial properties.

However, if the antibacterial agent is simply attached to the stockings in this way, the antibacterial agent will not be retained in the stockings sufficiently, and the antibacterial agent will come off from the stockings after being washed several times, resulting in There was a problem in that antibacterial properties were significantly reduced.

In addition, antibacterial agents that are commonly used to impart antibacterial properties to stockings have the effect of killing microorganisms, so as mentioned above, such antibacterial agents are added during softening processing to give stockings antibacterial properties. However, when antibacterial agents were added, treatment of wastewater containing the above-mentioned antibacterial agents became a problem.

[Problems to be Solved by the Invention] It is an object of the present invention to solve the above-mentioned problems when imparting antibacterial properties to stockings.

In other words, the present invention provides stockings with antibacterial properties, etc., as described above, that even if the stockings are washed many times, the antibacterial properties of the stockings do not easily decrease due to washing, etc. It is an object of the present invention to provide stockings that do not pose a problem in the treatment of wastewater when antibacterial properties are applied to the stockings.

[Means for Solving the Problems] In the present invention, in order to solve the above problems, at least a part of the stockings (1) is knitted using antibacterial nylon yarn (2), and the stockings (1) The extract extracted from the garlic cloves was dyed through metal salts.

Here, the antibacterial nylon thread (2) used to knit the stockings (1) includes silver ions, copper ions,
Since metal ions such as zinc ions have antibacterial properties, it is also possible to use thin wires or powders of these metals adhered to or added to nylon threads, or nylon threads containing these metal compounds. However, as mentioned above, in products that use metal itself, the specific gravity and Young's modulus of the metal are significantly different from those of nylon, so there are problems such as poor compatibility between the two, and in products containing metal compounds, However, there are problems such as metal compounds affecting nylon.

For this reason, the antibacterial nylon thread (2) used to knit the stockings (1) is made of zeolite-based solid particles that retain metal ions as described above. After spinning a nylon thread containing the added mixture or zeolite solid particles in the step, the nylon thread is treated with a solution containing the metal salts mentioned above, and at least a portion of the zeolite solid particles are added to the nylon thread. It is preferable to use one that retains the above metal ions.

Here, the above-mentioned zeolite solid particles have a specific surface area of 1'50 m2/g or more (based on anhydrous zeolite), and have a zeolite component (7) Si
It is desirable to use one having a molar ratio of 02/Al1203 of 14 or less, preferably 11 or less.

In this way, by using zeolite solid particles with a specific surface area of 150 m2/g or more and a zeolite component Si027A (1203 molar ratio of 14 or less), sufficient electrical metal ions are uniformly distributed in the zeolite solid particles. The zeolite-based solid particles are fixed to the zeolite and have a sufficient bactericidal effect. In addition, such zeolite solid particles have excellent acid resistance and alkali resistance, and are also inexpensive and economically advantageous.

Further, the zeolite solid particles used here may be either natural or synthetic. For example, natural zeolite includes analcime.

Further, it is desirable to use such zeolite-based solid particles having a particle size of 5 μm or less, preferably 2 μm or less, and furthermore, the content of the zeolite-based solid particles is 0.5 μm or less. It is desirable that the content be in the range of 0.05 to 10% by weight.

On the other hand, when dyeing the stockings (1) as described above with the extract extracted from Kihada through a metal salt, generally, after dyeing the stockings (1), the stockings (1) are dyed with a metal salt. The stocking (1) is immersed in a solution to impregnate the metal salt into the stocking (1), and then the stocking (1) is immersed in a solution diluted with the extract extracted from Kihada to extract the Kihada. The stocking (1) is dyed with the extracted extract by the metal salt that has been previously impregnated into the stocking (1).

[Function] In the stocking according to the present invention, at least a part of the stocking (1) is knitted using the antibacterial nylon thread (2) as described above, and the stocking (1) is made of an antibacterial nylon thread (2). Since the extract is dyed through metal salts, the interaction between the antibacterial nylon thread (2) and the extract extracted from the stockings (1) imparts sufficient antibacterial properties. Become.

In addition, in addition to using antibacterial nylon thread (2) in which the nylon thread itself that knits the stockings (1) has antibacterial properties, it is also possible to dye the stockings (1) with the extract extracted from the tree through metal salts. Even if the stockings (1) are washed many times, the antibacterial properties of the stockings (1) are unlikely to deteriorate due to washing, and sufficient antibacterial properties can be obtained over a long period of time.

Furthermore, since it uses extract extracted from Kihada, there is no problem with wastewater treatment.

In addition, as antibacterial nylon thread (2), zeolite solid particles holding antibacterial metal ions as described above may be added and mixed at any stage before spinning the nylon thread, or zeolite After spinning a nylon thread containing zeolite solid particles, this nylon thread is treated with a solution containing the above metal salts, and at least a portion of the zeolite solid particles hold the metal ions. Antibacterial metal ions are well retained in the nylon thread,
More stable antibacterial properties can be obtained.

[Example] Next, stockings according to an example of the present invention will be specifically described based on the accompanying drawings.

(Example 1) In this example, the stocking (1) has a panty part (11), a leg part (
Pantyhose (1) is manufactured by sewing two tubular knitted fabrics in which the pantyhose (12) and toe part (13) are integrally knitted at the crotch part.

Here, in the pantyhose (1) of this embodiment, the panty portion (11) is made of commonly used raw yarn for stockings such as woolly nylon or covered yarn with polyurethane elastic yarn as the core yarn. Use,
It is knitted into a stretchy knitted structure.

In addition, when knitting the leg portion (12), as shown in FIG. , 20 denier polyurethane elastic thread is used as the core thread (21), and 13 denier polyurethane elastic thread is used as the covering thread (22).
In addition to using denier nylon filament yarn, a 15 denier/3 filament antibacterial nylon yarn (2) in which metal ions were held by zeolite solid particles was used.

Specifically, as the above-mentioned antibacterial nylon thread (2), Ribfresh N (trade name) manufactured by Kanebo ■ was used.

Then, the double covered yarn (20) and the antibacterial nylon yarn (2) are alternately knitted in a 1=1 ratio for each course, as shown in FIG. 3, to knit the leg portion (12). I made it stand.

In addition, when knitting the toe part (13), the same 1
5 denier/3 filament antibacterial nylon thread (2)
In addition, 40 denier/10 filament woolly nylon yarn was used, and as in the case of the leg portion (12), these yarns were knitted in a 1=1 ratio.

After knitting the pantyhose (1) in this way, as is generally done, the pantyhose (1) is placed in a dye solution using a dye that exhibits an appropriate color at about 95°C. After soaking for 60 minutes, the pantyhose (1) is washed with water for about 10 minutes, and then color-fastened at about 80°C for about 10 minutes.
I tried washing it with water for a minute.

Next, as a mordant containing a metal salt, Danfix Hc (trade name) manufactured by Nitto Boseki, which contains copper, was used, and the mordant solution containing 0.1% by weight of this mordant was added as described above. The dyed pantyhose (1) is heated to approximately 60°C.
Soak this pantyhose (1
) was impregnated with the above metal salt, and then the pantyhose (1) was washed with water for about 10 minutes.

Then, about 60% of the pantyhose (1) was placed in a solution containing 1.5% by weight of the extract extracted from Kihada.
The pantyhose (1) were immersed for about 20 minutes at a temperature of 0.degree. C., and the extract extracted from the skin was stained with the pantyhose (1) through the impregnated metal salt as described above.

Then, after washing the pantyhose (1) dyed with the extract extracted from the body in water for about 10 minutes, 3% by weight of MX2087 (trade name) manufactured by Kao ■ was applied.
1% by weight of Evafanol N-7 (trade name) manufactured by NICCA CHEMICAL ■, ESN-741 (trade name) manufactured by Hosha Yushi Kogyo ■
1% by weight, Ultra MT170 manufactured by Mihejima Chemical Industry ■
The pantyhose (1) is immersed in a softening liquid containing 0.8 g/A of (trade name) at about 50°C for about 20 minutes to soften the pantyhose (1). I tried to complete (1).

(Example 2) In this example, pantyhose (1) were manufactured in almost the same manner as in Example 1. However, in this example, the leg When knitting section (12), instead of the double covered yarn (20) used in Example 1, a core yarn made of 20 denier polyurethane elastic yarn (
A single covered yarn is used around the toe portion (13
) used in Example 1.
Instead of the denier/10 filament woolly nylon thread, a 35 denier/10 filament woolly nylon thread was used.

And, regarding the above-mentioned exceptions, Example 1.

Pantyhose (1) were manufactured in the same manner as in the case of .

Next, for each of the pantyhose (1) of Examples 1 and 2 manufactured as described above, the antibacterial effect at the leg portion (12) and toe portion (13) was evaluated.

Here, to evaluate the antibacterial effect, we conducted an antibacterial test using the commonly used shake flask method.

In this antibacterial test using the shake flask method, Klebsiel pneumonia (Klebsiel Iapne) was the bacterial species.
The number of viable bacteria was measured from colonies obtained by culturing Klebsiella pneumoniae using Klebsiella unoniae), and the number of viable bacteria of Klebsiella pneumoniae measured from colonies before shaking was used as a sample for measurement. While adjusting the pantyhose (1) of Examples 1 and 2 above, the number was adjusted to 1.6 x 10'. I prepared what I went to twice.

Then, 1 hex of each punch chair of Examples 1 and 2 before washing and after washing 5 times as described above (1)
, the leg part (11) and the toe part 13) respectively.
Cut out the - section to obtain 0.75±0.05g of each specimen, and each of these specimens was determined to have a viable count of Klebsiella pneumoniae of 1.
After adding it to the 6 x 10' sample above, each sample was shaken for 1 hour using a wrist action shaker, and the number of viable bacteria in each colony that fell after shaking was measured, as well as the sterilization rate (%) of each sample. I tried to ask for.

Regarding the sterilization rate (%), the number of viable bacteria in the colony before shaking (1.6xlO4) is A, and the number of viable bacteria in the colony after shaking for 1 hour is B, and the following [1
] Calculated using the formula.

j (Here, each pantyhose (1) of Examples 1 and 2
Using each sample obtained as above, the viable colony count B and sterilization rate (%) after shaking for 1 hour were determined, and the results are as shown in Table 1 below. Met.

Table 1 As is clear from the results, like the pantyhose (1) of Examples 1 and 2 above, they were knitted using antibacterial nylon yarn (2), and the extract extracted from the kimono was knitted using antibacterial nylon thread (2). Leg part dyed via metal salt (12)
The toe portion (13) exhibits high antibacterial properties, and even when washed, the antibacterial properties do not deteriorate much, and sufficient antibacterial properties can be obtained for a long period of time.

In addition, in the above Example 1.2, stockings (
Although the case where 1) is pantyhose < 1) has been described, the stockings (1) according to the present invention are not limited to the pantyhose (1) as described above, but can also be over-knee stockings that reach up to the knees. , full-length stockings that reach the base of the thigh, etc.

[Effects of the Invention] As detailed above, in the stocking according to the present invention, at least a part of the stocking is knitted using antibacterial nylon thread, and the extract extracted from the stocking is knitted with metal. Because the dyeing was carried out through the salt, the interaction between the antibacterial nylon thread and the extract extracted from the soybeans made the stockings sufficiently antibacterial.

In addition, by using antibacterial nylon thread that has been given antibacterial properties to the nylon thread used to knit the stockings, and by dyeing the extract extracted from kihada through metal salts, it is possible to prevent Even when washed many times, the antibacterial properties of I/Kings do not deteriorate much.
It has become possible to obtain sufficient antibacterial properties over a long period of time.

Furthermore, since it uses extract extracted from Kihada, there is no longer the problem of wastewater treatment, which was the case in the past.

In addition, antibacterial nylon threads include those in which zeolite-based solid particles holding antibacterial metal ions are added and mixed at any stage before spinning the nylon thread, and nylon threads containing zeolite-based solid particles. If the thread is treated with a solution containing antibacterial metal salts to retain metal ions in at least a portion of the zeolite solid particles, the antibacterial metal ions will be sufficiently retained in the nylon thread. This made it possible to obtain stockings with even more stable antibacterial properties.
