The present invention relates to a method for manufacturing tissues to which a functional substance is added, and more particularly, to a method for preparing tissues by maximizing the efficacy of functional additives by coating the functional additives directly on the tissues in a tissue processing process. .

In general, ocher has excellent ability to control its own temperature and emits a large amount of far infrared rays, which helps to prevent aging, promote blood circulation, and relieve stress, and has antibacterial activity against various fungi such as molds. It is known to have a function of adsorbing harmful gases such as odor and ammonia odor.

Therefore, there are more and more cases of using ocher for daily necessities, and if you look for such examples, you can find examples of using ocher for non-woven sheets of sanitary napkins and diapers, as well as other examples of ocher bricks. .

 On the other hand, in the method of applying ocher in tissues, there is an example of applying ocher by dyeing fibers with natural dyes by making ocher solution by mixing ocher in water in a papermaking process. Since the main ingredient is calcium carbonate and the charge is very weak and the bond with the negatively charged fibers is very low, the retention of paper is very low, and it is not considered to express the actual ocher function, and the ocher solution is not applied directly to the tissue. Indirect use can be seen. Another example is to impart the functionality of the ocher by coating the ocher on the paper pipe to which the toilet paper is wound in toilet paper (aka roll toilet paper). However, this is because the ocher is not applied directly to the tissue, but because the ocher is applied to the branch pipe, it may be considered to be applied indirectly.

In addition, look at the tissue application examples of the functional additives disclosed in the present invention in addition to loess, Patent Application No. 10-2004-0099261 'The manufacturing method of antimicrobial functional toilet paper and cosmetic toilet paper impregnated with silver nano colloid' in a certain concentration After dilution with water, the wet-web is sprayed to hold the silver nanoparticles. In addition, Korean Patent No. 004034 'Tissue paper with antibacterial skin lotion' has developed a lotion composition containing antibacterial substances to combat bacteria and viruses, and a manufacturing technology of antibacterial tissue using the same. Adopted a method of applying the entire surface to the surface. The above two methods share the same purpose in that the tissue is added to the tissue to produce a tissue that highlights the functionality in the general tissue, and most functional tissues use the above two methods. However, the method of spraying the wet-web in the wet-end process adopted in the manufacturing method of antimicrobial functional toilet paper and cosmetic toilet paper impregnated with silver nano colloid cannot be suspended in the fiber network. Silver nanoparticles to be added may be lost between the porous fibrous tissue and the perforated wool (felt), and there is a disadvantage in that a large amount of silver nanoparticles must be sprayed to provide functionality. In addition, the technology of 'tissue paper with antibacterial skin lotion' to apply the antimicrobial lotion composition to the entire surface of the dried web (web), but there is an advantage that can be evenly applied to the entire tissue without loss of antimicrobial lotion composition, lotion If the treated tissue has more than one layer, it may be difficult to attach the web and the web, resulting in separation of the layers.

On the other hand, the present invention is a deco and dezzle method in the dry end of the tissue manufacturing process by using an adhesive to increase the bonding force between the web (web), which is a component of the tissue to the user in using the tissue and the web In addition to solving the problem of delamination of the various simultaneous addition of various functional additives, there is an advantage that can be held in the tissue without loss of additives. It is also a method used to emphasize the design, such as applying embossing to tissues by mixing inks of different colors.

The present invention has been made in view of the above, the present invention is mixed with the adhesive and the functional additives including ocher in the deco and dezzel process and inserted into the web with the adhesive to coat the functional additives directly on the tissue The purpose of the present invention is to provide a method for preparing a tissue to which a functional material is added to maximize the efficacy of the functional material.

When the predetermined functional material and the adhesive are mixed in the mixing tank 11 as described above, the mixture of the mixed functional material and the adhesive is introduced into the input tank 13 via the transfer line 12. The mixture of the functional material and the adhesive in the input tank 13 is adjusted to have a certain viscosity so as to facilitate the input into the layer regulating member chamber 15 which will be described later (S42). That is, the viscosity is adjusted by adding a liquid having a hydroxyl group so that the viscosity of the mixture is 100 ~ 500cps. The mixture of the viscosity-adjusted functional material and the adhesive in the input tank 13 is introduced into the layer regulating member chamber 15 via the mixture input line 14.

The mixture of the functional material and the adhesive introduced into the layer regulating member chamber 15 is introduced into a tissue composed of a plurality of webs to bond the webs and simultaneously coat the functional material to form a tissue to which the functional material is added. In the present embodiment, the tissue includes two webs, that is, a first web and a second web. Looking at this in detail as follows.

Referring to FIGS. 2 and 3, the mixture of the functional material and the adhesive introduced into the layer regulating member chamber 15 is formed by the layer silencing member (also referred to as DOCTOR BLADE) inside the layer regulating member chamber 15. It is uniformly applied to the enilox roll 23 (S43).

The mixture applied to the enilox roll 23 is transferred to the rubber roll 24 facing the enrols roll 23 (S44).

The mixture of the functional material and the adhesive displaced in the rubber roll 24 is transferred to the first web passing between the rubber roll 24 and the first embossing roll 25 facing the rubber roll 24 (S45).

As shown in FIG. 2, the arrow A represents the transport path of the first web. The first web is a web on which macro embossing is formed, and the first web on which macro embossing is formed through an embossing process is conveyed by the first transfer roll 26 and the first embossing roll 25. In addition, arrow B shows the conveyance path of a 2nd web. The second web is a web having micro embossing, and the second web having micro embossing through an embossing process has a second embossing roll facing the second feed roll 28 and the first embossing roll 25. 27).

Here, when the first web in which the mixture is displaced passes through the first embossing roll 25, the second web is also laminated while passing through the second embossing roll 27 (S46). Thus, the mixture is positioned between the first web and the second web, so that the first web and the second web are adhered and at the same time a functional material is coated between the first web and the second web.

As such, since the functional material is directly inserted into the tissue (between the first web and the second web), the specific effects of the functional material can be effectively exerted. In addition, since the functional material is not directly exposed to the outside of the tissue and is positioned between the first web and the second web, the functional material does not directly contact the skin, thereby preventing skin problems.

The laminated first web and the second web are conveyed in an arrow C path, where the mering roll 29 is adapted to distribute the mixture evenly between the first web and the second web, ie to evenly distribute the adhesion and the functional material. A predetermined pressure is applied to the laminated first web and the second web (S47).

The first and second webs are then firmly bonded to complete the tissue to which the functional material has been added. Figure 4 shows the structure of the tissue to which the functional material is added through this process, as shown, the tissue 30 has a macro embossing 31 and a micro embossing 32 having a bear pattern, A functional material is coated on the first web forming the macro ambossing 32.

In this way, the functional material is mixed into the adhesive in the dry end, and then inserted and coated between the first web and the second web, so that the adhesive property is superior to that of the functional material added in the conventional wet end. There is an excellent advantage.

In addition, the functional additives described above can be prepared a tissue containing a variety of functional materials that can be mixed freely to satisfy the taste of the consumer.

On the other hand, in the present embodiment has been described by taking a tissue consisting of two layers (two webs) as an example, the present invention is not limited to this, it is also applied to a tissue consisting of three or four layers and can exhibit the same effect.

Although preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described specific embodiments. That is, those skilled in the art to which the present invention pertains can make many changes and modifications to the present invention without departing from the spirit and scope of the appended claims, and all such appropriate changes and modifications are possible. Equivalents should be considered to be within the scope of the present invention.

Thus, according to the tissue manufacturing method to which the functional material according to the present invention is added,

First, since the functional material is directly inserted and coated between the webs, it is possible to effectively exhibit the unique effects of the functional material.

Second, since the functional substance does not come in direct contact with the skin, users with sensitive skin can use the tissue without skin trouble.

Third, since the functional materials to be added can be variously combined, it is possible to manufacture tissues exhibiting various functions suitable for the taste of consumers.
