HYDROPHOBIC AID COMPOSITION FOR IRONING AND METHOD OF PREPARING SAME

[Industrial use]

The present invention relates to a water repellent iron adjuvant composition and a method for producing the same, and more particularly, to a water repellent iron adjuvant composition and a method for producing the same, which can impart a protective effect and an antimicrobial effect of a fiber by using a water repellent agent.

[Prior art]

Garment finishing agents include aerosol type and manual spray type depending on spray type, and ironing aid and iron paste depending on function. Of these ironing finishes, ironing aids conventionally used water to reduce the friction when ironing to make ironing easier. Recently, in addition to these simple functions, ironing aids to improve the firmness of the fibers, antistatic, etc., aerosol-type ironing aids containing starch ingredients, and manual spray-type ironing containing dextrin, polyvinyl alcohol, carboxymethyl cellulose, etc. Supplements are commercially available.

However, since the effects of using ironing aids are almost the same as using water, most households still use water as an ironing aid.

The present invention is to solve the above problems, an object of the present invention is to form a water-repellent film on the surface of the fiber using a water repellent to give a protective effect and antimicrobial effect of the fiber can exhibit a significantly different effect than when using water It is to provide a water repellent ironing aid composition.

Another object of the present invention is to provide a water repellent ironing aid composition which can block fiber contamination from household pollutants using a water repellent.

Still another object of the present invention is to provide a method for preparing a water-repellent ironing adjuvant composition having the above-described physical properties.

In order to achieve the above object, the present invention provides a water-repellent ironing aid composition comprising a fluorine-based compound, alcohol, antibacterial agent and water.

Hereinafter, the present invention will be described in more detail.

The water repellent ironing aid composition of the present invention includes a fluorine-based compound, alcohol, water and antibacterial agent.

As the fluorine-based compound, a perfluoroalkyl acrylate copolymer or a perfluoroalkyl methacrylate may be used as the water repellent main component, and preferably a perfluoroalkyl acrylate copolymer is used. The perfluoroalkyl acrylate copolymer is a fluorine-based compound having alkylation with fluorine to increase water dissipation and to increase stability by mixing an acrylate copolymer. In addition, perfluoroalkyl acrylate copolymer is not only excellent in water repellent effect, but also attached to the surface of the fiber when ironed with a very stable component even at a high temperature of 200 ° C. or more, and is excellent in effect of imparting a water repellent effect.

The amount of the fluorine-based compound is preferably 0.5 to 20% by weight, when the amount of the fluorine-based compound is less than 0.5% by weight, there is a problem that the water repellency is inferior, and when the amount exceeds 20% by weight, the frictional force increases when ironing There is this.

As the alcohol, isopropyl alcohol or ethanol may be used as a solvent for the fluorine compound and an iron effect increasing agent. The alcohol component is a component that volatilizes when ironing, which increases the dispersibility of the fluorine-based compound and finely splits the particles during spraying, thereby coating a large area with a small amount and reducing friction when ironing, thereby smoothing the legs. It is an ironing effect synergist.

The amount of the alcohol is preferably 5 to 50% by weight, if the amount of the alcohol is less than 5% by weight, there is a problem that the dispersion and friction of the water-repellent component is inferior, and when the amount exceeds 50% by weight there is a problem of ignition.

The antimicrobial agent is a substance that gives antimicrobial activity, and may use 2,4,4-trichloro-2-hydroxy-diphenyl ether (hereinafter referred to as "trichloroic acid"), salicylic acid, silver colloid or benzalkonium chloride. Preferably, triclosan is used. Triclosan is a fungicide known to have a long lasting bactericidal effect. According to the MSDS material safety data sheet, triclosan is a very safe material including oral toxicity.

The amount of the antimicrobial agent is preferably 0.1 to 1.0% by weight, and if the amount of the antimicrobial agent is less than 0.1% by weight, there is a problem in that the antimicrobial activity is lowered.

The water repellent ironing aid composition of the present invention may further comprise a stabilizer of 2Na-EDTA, 4Na-EDTA or butylated hydroxy toluene (BHT).

The water repellent ironing adjuvant composition of the present invention may further comprise a fragrance. If the fragrance is further included, the fragrance may be imparted to the fibers during use. As such a fragrance, any of those generally used for fibers such as combination fragrance, natural fragrance, and immersion fragrance may be used, and the amount thereof is 0.05 to 1.0 parts by weight based on 100 parts by weight of the total water-repellent ironing aid composition. If the amount of the fragrance is less than 0.05 parts by weight based on 100 parts by weight of the total water-repellent ironing aid composition, there is a problem that the odor falls.

In addition, the water-repellent ironing aid composition of the present invention may further include a dye. The dye may be blue # 1, red # 2 or green # 204, the amount is preferably 0.00001 to 0.001 parts by weight based on 100 parts by weight of the total water-repellent ironing aid composition. If the amount of the dye is less than 0.00001 parts by weight, there is a problem that the contents do not exhibit color, and when it exceeds 0.01 parts by weight, there is a problem of dyeing and coloring.

The water repellent ironing aid composition of the present invention may also further comprise glycerin or 1,2-butylene glycol.

The method for producing the water-repellent ironing adjuvant composition of the present invention includes a step of mixing a first mixture containing a fluorine-based compound and an alcohol and a second mixture containing water and an antibacterial agent at a stirring speed of 200 to 3000 rpm. If the stirring speed is greater than 300rpm there is a problem that a lot of bubbles are formed, if the lower than 200rpm there is a problem that does not evenly dispersed. It is preferable to perform the said mixing process for 5 to 100 minutes. If the mixing process is carried out in less than 5 minutes, the dispersion is not good, and 100 minutes is sufficient, so there is no need to perform any more.

The weight percent in the following description is an amount based on the total weight of the water repellent ironing aid composition.

The first mixture is prepared by mixing 0.5 to 20% by weight of fluorine-based mixture with 5 to 50% by weight of alcohol at a stirring speed of 100 to 3000 rpm in a mixer. At this time, the fragrance may be further added to the first mixture in an amount of 0.05 to 1.0 parts by weight based on 100 parts by weight of the total ironing aid composition, and mixed.

The second mixture is prepared by mixing 0.1 to 1.0 wt% of the antimicrobial agent at 100 to 3000 rpm in a mixer in 30 to 60 wt% of water. In this case, the second mixture may be further mixed in an amount of 0.0001 to 0.01 parts by weight based on 100 parts by weight of the total ironing aid composition.

When explaining an example of the method of ironing the fiber with the water-repellent ironing aid composition of the present invention described above, the fiber is sprayed 2-3 times to iron the fiber at a temperature of 200 ℃ or more. According to this method, a water-repellent film is formed evenly on the fiber, which can be made into a waterproof fiber for a certain period of time.

Such a water-repellent ironing aid composition of the present invention, along with the ironing preservation function and grass feeding effect, can block fiber contamination from household pollutants such as kimchi broth, coffee, green tea, muddy water, milk, etc., with water repellency, waterproof The fiber softening effect through antistatic can be given to a fiber.
