1 is a flow chart showing a process for producing a functional leather containing an oriental herbal extract according to an embodiment of the present invention.
Fig. 2 is a side cross-sectional view of the functional leather containing the herbal extract prepared by the manufacturing method of Fig. 1;

The embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the following embodiments.

In addition, to include an element throughout the specification does not exclude other elements unless specifically stated otherwise, but may include other elements.

The functional leather of the present invention is applied to products such as bags, clothes, shoes, and furniture which are inevitably in contact with the human body when it is worn directly on the human body or when used, and is manufactured by the manufacturing method according to one embodiment as follows.

Referring to FIG. 1, first, an extract solution for oriental medicine is prepared (S1). The herbal extract solution is prepared by extracting at least one natural herbal ingredient of purified cinnamon, licorice, mugwort, green tea, Houttuynia cordata, and white wool, which has a sterilization and antibacterial action as a non-toxic, environmentally friendly ingredient, with purified purified distilled water. The extraction is performed using a generally known method, and a detailed description thereof will be omitted. In addition, it is possible to remove some unnecessary foreign substances by the filtration process, if necessary, by extracting the herbal extract solution, which can be sterilized and sterilized in a short time without adverse effect on the human body, And it can play a role of effectively eliminating harmful smell generated in leather through the effect of removing harmful bacteria. At this time, according to the herbal composition contained in the herbal extract, the leather can emit a unique fragrance, thereby enhancing the odor removal effect if necessary, or producing a leather product having a unique fragrance desired by the user.

The herbal extract is prepared by extracting 100 parts by weight of the purified water so that the oriental component is 10 to 50 parts by weight. Preferably, the herbal composition contains 1.5 to 7.5 parts by weight of cinnamon, 0.1 to 5.5 parts by weight of licorice, 0.05 to 3.5 parts by weight of mugwort, 0.2 to 3.5 parts by weight of green tea, 0.2 to 5.5 parts by weight of horseradish, 3 to 30 parts by weight.

If the ratio of the herbal ingredients is less than 10 parts by weight, there may be a problem that the desired effects of the herbal ingredients such as antimicrobial activity, sterilization and deodorization are not realized properly. If the proportion of the herbal ingredients exceeds 50 parts by weight, There is a possibility that the rate of increase of antibacterial, sterilizing and deodorizing effect is reduced, which is not economical.

Next, the natural or artificial leather that has undergone the pre-treatment step is sufficiently impregnated with the extracted one-sided extract (S2). Since the leather is made of a three-dimensional network structure, when the one-packed extract is immersed in the container containing the one-packed extract, the one-packed extract can be impregnated uniformly throughout the leather while being filled into the nets of the leather.

Next, the leather impregnated with the herbal extract is dried in a dryer at a temperature of 70 to 90 캜 (S3). If the drying temperature is lower than 70 ° C, there is a problem that the drying time is increased and the production efficiency is lowered. If the drying temperature is higher than 90 ° C, the leather may become too stiff after drying.

The drying time of the leather is preferably about 12 to 36 hours, and the water content of the dried leather is 15% by weight or less. At this time, if the drying time is less than 12 hours, some of the inside of the leather may not be completely dried, and if the drying time exceeds 36 hours, the production efficiency may be lowered and the leather may become too stiff after drying. If the water content of the dried leather exceeds 15% by weight, the concentration of the herbal extract solution is too low to achieve the desired antibacterial, sterilizing and deodorizing effect.

Next, as shown in FIG. 2, a coating layer 20 is formed on one side of the dried leather 10. The coating layer 20 may function as an adhesive layer for adhering a paint layer, a release paper, or the like, which exhibits hues, or a foam layer for providing a predetermined elasticity, depending on the components of the base material. Although the coating layer 20 is illustrated as a single layer in the present embodiment, the present invention is not limited thereto. The coating layer 20 may have a structure in which a plurality of coating layers 20 are stacked.

In this case, the coating layer 20 may be formed, for example, by printing or applying a coating solution prepared by a specific component and method on one surface of the leather 10, or alternatively, a coated paper may be prepared using the coating solution, To the surface of the leather (10), and then pressing it with a roller or the like. At this time, the coating liquid may be a special coating liquid containing a porous material described later.

Hereinafter, an embodiment for manufacturing a coating liquid applied to the coating layer 20 will be described.

The coating solution may be prepared by mixing 5 to 20% by weight of the first porous material and 80 to 95% by weight of the second porous material to prepare a mixed material, mixing the mixed material with the base material, In this case, the base material may be one of the paints having a color desired by the user when the coating layer 20 plays a role of a paint layer, and may be one of generally known adhesives when the role of the coating layer 20 is an adhesive layer The coating layer 20 may be one of foamable materials such as urethane in the case of a foam layer, and the present invention is not limited thereto. The porous material used for the first and second porous materials may be silica gel, zeolite, bentonite activated carbon, or the like, which has pores therein. It is not.

The first porous material may include a porous material containing at least one of silver (Ag), zinc (Zn), zirconium (Zr), titanium (Ti), and platinum (Pt) Impregnated. At this time, the ethanol may be impregnated with 100 to 300 parts by weight, preferably about 150 parts by weight based on 100 parts by weight of the porous material containing the metal. The ethanol is filled in pores of the porous material to prepare a mixed material by mixing the first and second porous materials. When the mixed material is mixed with the base material, the base material is prevented from filling the space of the porous material . When the leather is dried after the coating layer 20 is formed due to the low volatilization temperature, the ethanol is rapidly volatilized and removed from the coating layer 20, and the coating layer 20 is filled with the porous material of the first porous material pore is left as it is. Therefore, this empty space plays a role of adsorbing odor and germs, so that the antibacterial, sterilization and deodorizing effect of leather can be improved.

The second porous material includes a perfume and propylene glycol. The fragrance is a substance that emits a fragrance and serves to dilute or remove the odor of the leather. For example, it may be a fruit such as a lemon, an apple, a banana, or an orange, or a flower such as a rose, an acacia, Flavor, aroma of various plants such as lavender, peppermint, jasmine, or a special perfume such as coffee, chocolate, and ginseng, and the present invention is not limited thereto.

At this time, the fragrance is disposed in the holes formed in the porous material so that the fragrance of the product made of leather having the present coating layer can be maintained for a longer period of time by increasing the duration of fragrance, . The propylene glycol acts as a solvent to firmly fix the fragrance so that it is not released after being disposed in the hole of the porous material.

Preferably, the second porous material may include 80 to 95 parts by weight of a perfume and 5 to 20 parts by weight of propylene glycol per 100 parts by weight of the porous material. If the amount of the fragrance is less than 80 parts by weight, the void space of the porous material may not be filled up, and the fragrance may be weak or deterioration may be caused. If the fragrance is more than 95 parts by weight, There may be problems that are not economical due to lack of. If the amount of the propylene glycol is less than 5 parts by weight, the fragrance filled in the porous material can not be fixed at all, thereby deteriorating the consistency of the fragrance. If the amount of the propylene glycol is more than 20 parts by weight, There may be problems.

The base material may be, for example, a paint, an adhesive, urethane or the like as described above. Preferably, the base material may contain 97 to 99.95 wt% of the base material and 0.05 to 3 wt% of the mixed material of the first and second porous materials, 20,000 RPM at a high speed to prepare a coating solution. If the content of the base material is less than 97% by weight, the characteristics of the base material itself may be deteriorated. If the content of the base material exceeds 99.95% by weight, the effect of the porous material may not be exhibited properly have.

<Experimental Example>

In order to examine the directional effect of the leather of the present invention, 3 parts by weight of green tea, 5 parts by weight of the green tea and 22 parts by weight of the green tea were extracted with respect to 100 parts by weight of purified water, 30 parts by weight of the herbal extract was extracted, And dried at 80 ° C for 24 hours to have a water content of 13%. Then, a coating solution containing a porous material was coated on one side of the leather to form a coating. In Comparative Example 1, the same leather material was subjected to a pretreatment process, then the same one-side extract solution was applied to the surface with a brush and dried at the same temperature and time to form a leather without a coating layer. In Comparative Example 2, the same leather material was subjected to a pretreatment process, sprayed on the surface with a spray-type fragrance sold on the market, and dried at the same temperature and time to form a leather without a coating layer.

The leathers of these Examples and Comparative Examples 1 and 2 were placed in a room free from moisture to confirm that the directional effect lasted for a long time. A total of 10 smellers were regarded as having no smell if they recognized that there was an odor of at least 2 persons.

division Duration Remarks Example More than 30 days Comparative Example 1 one week Comparative Example 2 3 days

As a result, in the case of the example, even after one month, the fragrance did not greatly differ from the first, but in the case of Comparative Example 1, only two persons perceived the fragrance after one week, whereas in the case of Comparative Example 2, Later, only two people detected the fragrance. Thus, it can be seen that the examples have a much better directional continuity than the conventional leather (Comparative Examples 1 and 2).

The present invention is not limited by the above-described embodiments but is intended to be limited by the appended claims. It will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. something to do.
