It includes a second drying chamber (60) for winding, and a second winding roll (P2') for winding the finished deodorizing fabric (F2') while passing through the second drying chamber (60).

The antimicrobial material receiving tank 10 is provided with a pair of first coating rollers 15a and 15b for applying the antimicrobial material aqueous solution to the first fiber F1. One of the first coating rollers 15a and 15b is immersed in an aqueous solution of an antimicrobial material and rotated, so that an aqueous solution of an antimicrobial material is applied to the surface of the first fiber F1 passing between the first coating rollers 15a and 15b. .

A pair of second coating rollers 45a and 45b for applying an aqueous deodorant solution to the second fiber F2 is installed in the deodorant material receiving tank 40. One of the second coating rollers 45a and 45b is immersed in an aqueous deodorant solution and rotated, so that the second coating rollers 45a and 45b

A deodorant aqueous solution is applied to the surface of the second fiber (F2) passing through it.

The first high-frequency oven 20 is spaced apart from each other and alternately, high-frequency generation units 21 and 22 are installed. Accordingly, the first high frequency is evenly applied to one side and the other side of the first fiber F1 passing through the first high frequency oven 20.

The second high frequency oven 50 is spaced apart from each other, and the high frequency generators 51 and 52 are installed alternately. Accordingly, the second high frequency is evenly applied to one side and the other side of the second fiber F2 passing through the second high frequency oven 50.

Inside each of the first and second drying chambers 30 and 60, a plurality of rollers 30a and 60a supporting the first and second fibers F1 and F2 are installed, and the first and second drying chambers 30 (60) First and second blowers 31 and 61 for blowing wind for drying are installed outside each.

In the above-described device, for easy explanation, it is disclosed that antibacterial treatment is performed on the first fiber (F1) of one strand and deodorization treatment is performed on the second fiber (F2) of one strand. Of course, it can be antibacterial and deodorant on fibers.

Next, an antibacterial and deodorizing fabric manufacturing method according to the present invention performed by the above antibacterial and deodorizing fabric manufacturing apparatus will be described.

The first and second fibers used in the present invention (F1) (F2) are acrylic, polyester. Any selected from the group consisting of nylon

Use one

In order to perform the antibacterial and deodorant fabric manufacturing method according to the present invention, first, a step (S1) of applying the first fiber (F1) with an aqueous antibacterial material solution is performed. Step (S1) is carried out by passing the first fiber (F1) between the first coating rollers (15a, 15b), at this time, the antimicrobial material is applied to the first fiber (F1) in an aqueous solution state, so the first fiber (F1) ) Is evenly applied to the surface.

The antimicrobial material aqueous solution is mixed with silver fine particles with isothiazolones to prepare an antimicrobial material, and the antimicrobial material is mixed with at least one binder resin selected from the group consisting of urethane resin, acrylic resin, fluorine resin, and melamine resin. It is prepared by uniformly dispersing in water.

Such an aqueous solution of antimicrobial substances is prepared by dispersing or dissolving in the remaining amount of water to make the total amount of the antimicrobial substance aqueous solution 100%, silver fine particles 01 to 05%, isothiazolone 05 to 1%, and binder resin 5 to 20%. do.

If the content of silver fine particles and isothiazolone is less than the above range, there is a fear that the antimicrobial properties may not be sufficient, and if the content of the silver fine particles and isothiazolone is less than the above range, it is difficult to obtain a uniformly dispersed antimicrobial material. In addition, if the content of the binder resin is less than the above range, it is difficult to effectively attach the antimicrobial material to the first fiber (F1), and if it is more than the above range, the first fiber (F1) has a problem of deteriorating physical properties such as stiff touch.

It is preferable that the silver fine particles have an average particle diameter of 1 nm to 100 nm. If the average particle diameter is less than 1 nm, the effect is excellent, but the product price rises rapidly and there is a problem in commercialization, and if it exceeds 100 nm, there is a problem that the dispersibility in the aqueous solution of the antimicrobial substance decreases. The silver fine particles may be added to the antimicrobial material as they are, but commercially available as colloidal solutions in a sol state may be used, and in this case, there is an advantage of improving dispersibility.

[0031] Silver fine particles are excellent in sterilization and antibacterial activity as the particle size is smaller, and when reviewing the data tested so far, E. coli, Staphylococcus aureus, Salmonella, Vibrio, Shigella, pneumococcal, typhoid and MRSA with the strongest resistance (Methicillin-resistant yellow staphylococcus) has been reported to be 999% antibacterial and sterilizing. In other words, silver fine particles act directly on harmful bacteria of 10 nm, and by melting the cell membrane of harmful bacteria, they act with enzymes in the cell to block the inflow and discharge of nutrients, and block the respiratory function of harmful bacteria to prevent the production of APT in the cell, and to stop and regenerate the growth of harmful bacteria. It destroys the ability to kill harmful bacteria in a short time. Therefore, it is reported that almost all bacteria cannot live in contact with silver fine particles for more than 5 minutes.

Isothiazolone is a compound that has a wide range of bactericidal activity against many harmful organisms derived from animals and plants such as bacteria, fungi, and algae in powder form. This isothiazolone is used to inhibit the growth of harmful microorganisms.

The antimicrobial material composed of the silver fine particles and isothiazolone generates a synergistic effect and exerts a strong antibacterial ability.

Next, the step of irradiating the first high frequency to the first fiber (F1) to which the transferred antimicrobial material aqueous solution is applied, and fixing the antimicrobial material composed of silver fine particles and isothiazolone on the surface of the first fiber (F1) (S2) Perform.

Step (S2), while passing through the first high-frequency oven 20, the first fiber (F1) coated with the antimicrobial material aqueous solution, the first high frequency

This is a step in which the binder resin is firmly fixed to the first fiber F1 by irradiating the fiber F1 to induce a dielectric heating phenomenon in the binder resin.

When the first fiber (F1) is enlarged, as shown in FIG. 2, a number of fine grooves (F1a) are formed on the surface of the first fiber (F1). As the binder resin is instantaneously heated by the first high frequency, It penetrates into the fine groove F1a formed on the surface of the first fiber F1, and accordingly, the antimicrobial material A1 is firmly fixed to the surface of the first fiber F1. This step (S2)

Through this, the antimicrobial material A2 is firmly fixed to the first fiber F1, and accordingly, the antimicrobial material A1 is not removed from the first fiber F1 even when repeatedly washed or exposed to ultraviolet rays.

At this time, the frequency of the first high frequency irradiated with the first fiber F1 is in the range of 10 to 40 MHz, and the residence time in the first high frequency oven 20 is 13 seconds. If the frequency of the first high frequency is less than the above range, it is difficult to induce a dielectric heating phenomenon in the binder resin, and if it is more than the above range, the physical properties of the first fiber F1 itself may be changed and the touch may become stiff. Also the first high frequency oven

If the residence time in (20) is less than the above range, the binder resin is not sufficiently heated, and if it is more than the above range, the dielectric heating phenomenon proceeds in the first fiber (F1) and physical properties may change.

Next, a step (S3) of completing the antibacterial fiber (F1') is performed by drying the first fiber (F1) to which the antimicrobial material to be transferred is fixed. Step (S3) is to remain in the first fiber (F1) by passing the first fiber (F1) to which the antimicrobial substance is fixed through the first drying chamber (30).

Is to remove water.

Since the step (S2) proceeds rapidly, even if the antimicrobial material is fixed to the first fiber (F1), some water remains, and this material is completely removed while passing through the first drying chamber (30). In the first drying chamber 30, while the first fibers F1 are conveyed along the rollers 30a, the first blower 31 applies hot air having a drying temperature in the range of 40 to 70°C, and the first fibers F1 The drying time that) stays in the drying room 30 is 1 to 3 seconds.

If the drying temperature and drying time are less than the above range, water cannot be completely evaporated from the first fiber (F1), and if it is more than the above range, the physical properties of the first fiber (F1) may be changed.

Next, a step (S4) of applying the aqueous solution of the deodorant substance to the surface of the second fiber 21 is impregnated with the aqueous solution of the deodorant substance (S4). Step (S4) is carried out by passing the second fiber (F2) between the second coating rollers (25a, 25b), at this time, the deodorant material is applied to the second fiber (F2) in an aqueous solution state, so the second fiber ( It is evenly applied to F2).

[0042] A deodorant aqueous solution is pulverized and mixed with silica, titanium oxide and zinc oxide to prepare a deodorant material, and the deodorant material is selected from the group consisting of a urethane resin, an acrylic resin, a fluorine resin and a melamine resin. It is prepared by uniformly dispersing in water together with at least one binder resin.

The aqueous solution of such a deodorant substance contains 2 to 4% of silica, 03 to 08% of titanium oxide, 03 to 1% of zinc oxide, and 5 to 20% of the binder resin, and the remaining amount to make the total amount of the aqueous solution of the deodorant 100%. It is prepared by dispersing or dissolving in water.

If the content of silica, titanium oxide, and zinc oxide is less than the above range, there is a fear that the deodorizing property may not be sufficient, and if it is used above the above range, it is difficult to obtain a uniformly dispersed deodorant material. In addition, when the content of the binder resin is less than the above range, it is difficult to effectively attach the deodorant material to the second fiber (F2), and when the content of the binder resin is above the above range, there is a problem that the physical properties are deteriorated, such as stiff touch of the second fiber (F2) .

The silica powder is a colorless transparent solid and is preferably a porous silica having an average particle diameter of 01 to 10 µm. If the average particle diameter is less than 01 µm, it exhibits excellent effects by increasing the surface area, but there is a problem of increasing the price, and if it exceeds 10 µm, there is a problem that the washing durability is deteriorated. Porous silica powder plays a role in collecting odor components with fine porosity.

All.

It is preferable that the titanium oxide powder has an average particle diameter of 10 nm to 100 nm. If the average particle diameter is less than 10 nm, the effect is excellent, but the product price rises rapidly and there is a problem in commercialization. If the average particle diameter exceeds 100 nm, there is a problem that the dispersibility is lowered when preparing an aqueous solution.

It is preferable that the zinc oxide powder has an average particle diameter of 10 nm to 100 nm. If the average particle diameter is less than 10 nm, the effect is excellent, but the product price rises rapidly and there is a problem in commercialization. If the average particle diameter exceeds 100 nm, there is a problem that the dispersibility is lowered when preparing an aqueous solution.

The titanium oxide and zinc oxide described above decompose and remove odor components by having a photodecomposition catalytic ability. In addition, deodorant substances composed of titanium oxide, zinc oxide and silica generate a synergistic effect and exert a strong deodorizing ability.

Next, by irradiating a second high frequency to the second fiber (F2) coated with the transferred deodorant aqueous solution, the deodorant material consisting of silica powder, titanium oxide, and zinc oxide is fixed on the surface of the second fiber (F2). Step S5 is performed.

Step (S2) is a dielectric heating phenomenon in the binder resin by irradiating the second high frequency to the second fiber (F2) while passing the second fiber (F2) coated with the deodorant aqueous solution through the second high frequency oven (20). This is a step in which the binder resin firmly adheres the deodorant material to the second fiber (F2) by inducing it.

As shown in FIG. 2, when the second fiber F2 is also enlarged, numerous fine grooves A2 are formed on its surface. As the binder resin is instantaneously heated by the second high frequency, the second fiber F2 Penetrates into the fine grooves formed on the surface, and accordingly, the deodorant material A2 is firmly fixed to the surface of the second fiber F2. Through this step (S5), the deodorant material (A2) is firmly fixed to the second fiber (F2), and accordingly, even if repeatedly washed or exposed to ultraviolet rays, the deodorant material (A2) is converted into the second fiber (F2). Is not eliminated from

At this time, the frequency of the second high frequency irradiated with the second fiber F2 is in the range of 10 to 40 MHz, and the residence time in the second high frequency oven 20 is 1 to 3 seconds. If the frequency of the first high frequency is less than the above range, it is difficult to induce dielectric heating in the binder resin, and if it is more than the above range, the physical properties of the second fiber F2 itself may be changed and the touch may become stiff. Another 2nd high frequency oven

If the residence time in (50) is less than the above range, the binder resin is not sufficiently heated, and if it is more than the above range, the physical properties of the second fiber (F2) may be changed.

Next, a step (S6) of completing the deodorant fiber (F2') is performed by drying the second fiber (F2) to which the deodorant material to be transferred is fixed. Step (S6) is by passing the second fiber (F2) to which the deodorant material is fixed through the second drying chamber (60), remaining in the first fiber (F1).

It is to remove the water.

Since the step (S6) proceeds quickly, even if the antimicrobial material is fixed to the second fiber (F2), some water remains, and this material is completely removed while passing through the second drying chamber (60). In the second drying chamber 60, while the second fibers F2 are transported along the rollers 60a, the second blower 61 applies hot air having a drying temperature in the range of 40 to 70°C, and the second fibers F2 The drying time that) stays in the second drying chamber 60 is 1 to 3 seconds.

If the drying temperature and drying time are less than the above range, water cannot be completely evaporated from the second fiber (F2), and if it is more than the above range, the physical properties of the second fiber (F2) may be changed.

Next, a step (S7) of weaving the antibacterial fiber (F1') and the deodorizing fiber (F2') is performed. In step (S7), by weaving the antibacterial fiber (F1') and the deodorizing fiber (F2') with warp and weft, the antibacterial and deodorant fabric is completed.
