Hereinafter, the technical configuration of the present invention will be described in detail according to a preferred embodiment.

The antibacterial dyeing composition using sulfur of the present invention comprises: (a) preparing an antimicrobial composition by mixing carbon disulfide, sulfur, water and an emulsifier; (b) preparing a dye mixture 10 by adding and mixing a dye and an antimicrobial composition in a dye tank; (c) heating the dye mixture 10 and immersing the synthetic fiber yarn 20 into the dye mixture 10 continuously; (d) cooling, dehydrating and drying the synthetic fiber yarn 20; (e) a post-treatment step of removing the dye composition containing the antimicrobial composition that has not penetrated the opening of the molecular structure of the synthetic fiber yarn 20; (e) a post-treatment step of removing the dye composition in which the antimicrobial composition that has not penetrated the opening of the molecular structure of the synthetic fiber yarn is removed.

First, an antibacterial composition is prepared by mixing carbon disulfide, sulfur, water, and an emulsifier (a).

In the present invention, sulfur (S) having excellent antibacterial activity was selected as a substrate for antibacterial treatment of synthetic fiber yarns.

Sulfur is the symbol S (Sulfur Sulfur) and has an atomic number of 16, which is a non-metallic element with no taste and odor. In its natural state, it is present in pure sulfur, or in the form of sulfides or sulfates. As an essential element in life, two types of amino acids contain sulfur. It is the main component of fertilizer, and is also used in gunpowder, matches, pesticides, and disinfectants. Calcium sulfate, barium sulfate, lead sulfate, silver sulfate, etc. produced through the sediment formation reaction are white sediments and are stable to acids.

In order to dissolve the sulfur, carbon disulfide, that is, carbon disulfide is used. That is, sulfur is dissolved in carbon disulfide to dissolve the sulfur. At this time, since sulfur and carbon disulfide are mixed and generate heat, an appropriate amount of water is mixed, and an antimicrobial composition is mixed with an emulsifier to prevent layer separation from water. Manufacturing.

In particular, each amount of the composition to be mixed in the antimicrobial composition may be variously applied, but preferably 80 to 90% by weight of carbon disulfide and 10 to 20% by weight of sulfur are mixed, and emulsifiers 1 to 3 in a mixture of carbon disulfide and sulfur By mixing parts by weight, based on 40 parts by weight and to prepare an antimicrobial composition mixed with 60 parts by weight of water.

When mixing carbon disulfide and sulfur, when sulfur is less than 10% by weight, the antibacterial effect does not appear properly when mixed, and when it exceeds 20% by weight, synthetic fiber yarns become hard or stiff when mixed, as well as low economic efficiency. It is preferable to mix 10 to 20% by weight of sulfur with 80 to 90% by weight of carbon disulfide.

The mixture of carbon disulfide and sulfur is mixed with 1 to 3 parts by weight of an emulsifier to prepare an antimicrobial composition that is based on 40 parts by weight and mixed with 60 parts by weight of water. There is no antimicrobial effect when there is more water, so based on 40 parts by weight including a mixture of carbon disulfide and sulfur and an emulsifier, an emulsifier in a mixture of carbon disulfide and sulfur is less than 1 part by weight. When mixing in excess of 3 parts by weight, the color of the composition becomes cloudy and the economic efficiency is poor, so it is preferable to mix 1 to 3 parts by weight of the emulsifier in a mixture of carbon disulfide and sulfur, based on 40 parts by weight.

The emulsifier can use any of various known emulsifiers such as WO emulsifier or OW emulsifier.

When mixing each composition, it is preferable to mix using a stirrer or the like, and it is preferable to stir for 40 to 70 minutes with a stirrer.

Thereafter, a dye and an antimicrobial composition are added to the dye tank and mixed to prepare a dye mixture 10 (b).

To the dye tank 1, a dye and an antimicrobial composition are added and mixed to prepare a dye mixture 10.

The mixing ratio of the dye and the antimicrobial composition may be made variously, and preferably, the dye mixture is preferably mixed with 90 to 98% by weight of the dye and 2 to 10% by weight of the antimicrobial composition.

When the antimicrobial composition is less than 2% by weight, the antimicrobial effect decreases, and when it exceeds 10% by weight, the color of the dye is not easy to express. Therefore, 90 to 98% by weight of the dye and 2 to 10% by weight of the antimicrobial composition are mixed. It is desirable to do.

Thereafter, the dye mixture 10 is heated, and the synthetic fiber yarn 20 is continuously immersed in the dye mixture 10 (c), and the synthetic fiber yarn 20 is cooled and dehydrated and dried (d).

When the dye mixture 10 is heated, the dye tank 1 is heated to keep the dye mixture 1 at a constant temperature.

Synthetic fiber yarns 20 may be any of a variety of known synthetic fiber yarns such as polyester.

Polyester is a high-strength fiber when pulled, and it is not only unchanged in strength even when wet with water, but also has good durability, and is widely used as a material for various products used in real life such as cushion cushion bedding curtain bag.

In this way, synthetic fiber yarns such as polyester have a loose molecular structure between synthetic fiber yarns when the temperature rises, openings are formed, and when the temperature decreases, the openings are narrowed to form dense particles. In the present invention, the dye mixture 10 is used. When immersed in the synthetic fiber yarn by heating, it has an effect of heating the synthetic fiber yarn so that numerous openings 21 are widened on the surface of the synthetic fiber yarn 20, and the dye mixture 10 is opened in the opening 21. This is to ensure that the incoming.

At this time, the temperature of the dye mixture 10 is preferably maintained at a temperature of 120 ~ 180 ℃.

To dye the synthetic fiber yarn 20 Figure 4. Figure 6. When the temperature of the yarn in the tank rises by heating it with high heat in a closed state by putting a cone or yarn with a mixture of yarn and dye in the tank as shown in FIG. 7, the molecule expands when the temperature is increased, and shrinks when the temperature decreases. Due to the nature, the gaps between the molecules constituting the yarn of the synthetic resin are loosened, and the opening 21 is formed on a part of the yarn surface, and the dye mixture 10 is applied to the yarn between the openings 21 of the yarn surface made away from the molecules between the threads. In the step of penetrating and described below, when the temperature of the yarn is cooled by cooling the tank, the gap between the openings of the openings 21 of the opened yarn surface is closed, and the dye mixture 10 containing sulfur is trapped inside the openings 21. Since the dye mixture (10) remains in the yarn, the dye mixture is not separated from the yarn, so when dyeing the dye, the dye is separated from the yarn to prevent the dye from coming out of the coating or water repellent. Antibacterial and dyeing is completed without treatment.

In the prior art, dyeing and post-treatment processes such as antibacterial and water repellent treatments are performed. In the present invention, a synthetic fiber fabric is fabricated when dyed as shown in FIG. 3 by using a dye mixture (10) mixed with an antimicrobial composition having an antimicrobial function. 20) When the temperature itself rises, the opening (21) particles open and the dye particles and sulfur particles enter at the same time, and are adhered to the inside of the synthetic fiber fabric (20) so that they are not exposed. To maintain.

The synthetic fiber yarn 20 is cooled by a method such as natural cooling, and dehydration and drying can be performed by a variety of known methods.

Finally, the dye composition in which the antimicrobial composition that has not penetrated the opening of the molecular structure of the synthetic fiber yarn 20 is mixed is removed (e).

Such post-treatment may be performed through a known work, such as a tenter work, to remove the dye composition in which the antimicrobial composition that has not penetrated the surface of the synthetic fiber yarn 20 is mixed.

Figure 4 is a diagram showing the antibacterial test results of synthetic fiber yarn dyed with an antibacterial dyeing composition using the sulfur of the present invention.

As shown in FIG. 5, the antibacterial test result showed that the bacteriostatic reduction rate was 99.9% after 18 hours compared to the initial number of bacteria, and the antibacterial effect was excellent.

The antimicrobial dyeing composition using sulfur of the present invention as described above is mixed with a dye and an antimicrobial sulfur-containing antimicrobial composition and dyed synthetic fiber yarns without separate water repellent treatment or post-processing process only by dyeing the synthetic fiber yarn. At the same time, by allowing sulfur to be present in the synthetic fiber yarn, antibacterial treatment can be carried out by sulfur, which not only can significantly reduce the time of the dyeing and antibacterial treatment, but also has a very useful effect of reducing the cost.
