Description
The present invention relates to a method for producing a coating film having an antibacterial far-infrared ray radiation function and a coating film prepared thereby, and more particularly to a method for producing a coating film having antibacterial far-infrared radiation function widely used for metals, wood, fibers, And to a coating film thus produced.
In the field of metals, wood, fibers, textiles, various methods are being tried to increase the added value by adding additional functions or performance.
For example, a composition having various functions is contained in microcapsules and attached to the fabric by a binder, and the microcapsules are blown off by external impact during use, so that the functional composition contained in the capsules is diverged and acted upon. However, such a technology is not only complicated in its manufacturing process, but also has a low manufacturing cost and low practicality. When the microcapsule is blown, the functional composition instantaneously expands, have.
On the other hand, researches have been continuously carried out to enhance the added value by further imparting the functionality or maximizing the performance through the surface modification of the fabric.
The functional fabrics can be classified into the following three stages: polymer modification in the polymerization step, spinning and sticking of the functional material to the surface in the spinning step, and functionalization in the dyeing step . Among them, the functionalization can be easiest to be expressed in the dyeing step in terms of free usage development, and this performance must be maintained in repeated washing process during use or have a minimum use durability. Examples of the method of imparting the functional material in the double dyeing step include a method in which the treatment liquid is applied by a method such as dipping or spraying and then the liquid is fixed by heating or a method in which a resin capable of acting as a binder between the treatment liquid and the fabric is blended and immersed or coated A method of adhering to a fabric, a method of adhering a substance having a particle size similar to a dye and affinity to a fabric to the surface or inside of the fabric by a concentration gradient in a dyeing bath is widely used.
In view of the degree of durability of the functional material attached to the fabric in repeated use during use, it is best to add a functional material in the polymerization step to prepare a dispersion and a copolymer, The method also has good durability. However, the fabrics produced by this method are not preferable because of the problem of cost increase in using expensive functional materials because the functional materials are distributed evenly on the fabric surface as well as on the fabric surface.
In addition, since it is required to introduce an antibacterial substance into the fabric as a functional substance, the antimicrobial substance can improve the durability of the fabric by inhibiting the growth of bacteria and fungi that cause damage to the fabric component while living in the fabric . Such a fabric having antimicrobial activity blocks odor generation by preventing or suppressing the growth of microorganisms from the fabric as organic food. Additionally, antimicrobially treated fabrics can protect the fabric wearer from exposure to disease agents by killing pathogenic microorganisms.
Meanwhile, in the coating process of the fabric, the coating material is applied to the surface of the fabric in a state in which the coating material is directly brought into contact with the surface of the fabric material advancing in a predetermined direction by the guide rollers, Knife coating process is used to carry out the coating process through a series of processes such as scraping the coating material and adjusting the thickness of the coating material.
Various fabric fabrics may be coated with PU (polyurethane), acrylic, silicone or the like as a coating material on the surface thereof according to the purpose of use, and the coated fabric material is configured to pass through the dryer.
In such a coating process, the coating liquid is applied to the surface of the fabric and then dried. However, since it takes a lot of time to dry naturally, it is heat-treated (dried) through a dryer.
However, the functional fabric of the prior art has a problem that it can show the side effects of the human body due to the additive exhibiting the function, and due to the characteristics of the fabric, the lifetime of the function of the fabric due to continuous washing is endured, .

In addition, in the mixing step (300) of the aged pine needles essential oil and the elvan powder, aged pine needles oil mixed with Shin Nam aldehyde, which is a main component of cinnamon, is mixed with elvan powder to sufficiently fill the aged pine needles in the pores of the elvan powder. At this time, the elvan rock is a porous rock having innumerable voids therein, and its adsorption ability is remarkably improved in a powder state, and is widely used for purification of water quality and food processing.
In the present invention, the elvan pearl powder and the aged pine needles essential oil are mixed at a weight ratio of 6: 0.7 to 1.5, and if aged for 3 to 5 hours, the elongated pine needles are almost completely absorbed in the elvan powder to fill the internal pores.
Therefore, in the
Here, when the aged vinegar powder to be formed is applied to the fabric, the aged pine needles oil that is charged in the aged vinegar powder gradually emits, causing insects as well as aroma.
As another component of the antimicrobial layer, a water extract of lacquer and cinnamon is used. Such water extracts of lacquer and cinnamon exhibit strong antimicrobial activity and have an effect of inhibiting them from being contained by components such as ticks, mosquitoes and various insects. In order to obtain this effect, harmful substances which cause allergy among natural substances of lacquer and cinnamon should be removed by decomposition and oxidation by reacting with distilled water under heat and pressure. To this end, the contents of the lacquer and cinnamon were mixed in a sealed container having a content confirmation scale at a weight ratio of 1: 1, poured distilled water so that the weight ratio of water extract of lacquer and cinnamon to distilled water was 1: 3, It is characterized by adding and diluting 2% by weight of salt of distilled water, sealing the container, boiling the distilled water in a sealed container to half the volume while maintaining a constant thermal power, and using the obtained water extract of lacquer and cinnamon .
The antimicrobial layer is coated with a mixture obtained by mixing the aged Kobanstone powder filled with aged pine needles oil made of pine needles oil, cinnamon, and elvan powder with the water extract of lacquer and cinnamon. It is preferred to mix the branch components in a volume ratio of 9: 1. It has an advantage that the most preferable antimicrobial effect can be obtained in the above ratio.
