Description

Functional patches for pads comprising ferrite sintered bodies and zeolites are disclosed.

The present invention relates to a functional patch for a pad useful for a human body comprising a ferrite sintered body and a zeolite.

The sanitary pads to which the present invention is applied include sanitary napkins, infant or adult diapers, hygienic sheets for long-lying patients, and multi-layered masks. The common points of the sanitary pads listed above are that they consist of multiple layers of multiple layers and that they are worn for a long time in the human body. Therefore, sanitary pads can be said to be essential for healthful conditions.

The sanitary napkin is used as a daily necessity for adult women to absorb secretions such as menstrual blood and cold air. The secretion causes an unpleasant feeling to the user or people around the sanitary napkin due to the smell generated during absorption into the sanitary napkin. In addition, since the secretion is in a mucilage state, it maintains a wet state for a long time, and therefore, a horn condition is formed for the bacteria and fungus to live. Therefore, the user may be prone to itching or the skin may be damaged.

On the other hand, even in the case of diaper for infant or adult, a moist state is formed due to local discharge or excretion, thereby causing problems such as odor, itching and skin troubles when worn for a long time. In the case of a sanitary sheet for long- And a humid condition is created at the portion where the liquid is contacted with the liquid. In addition, even in the case of a mask to be worn on the mouth, the saliva discharged from the mouth while being worn is adsorbed on the mask as it is, and bad bacteria are reproduced along with the smell when worn for a long time.

Therefore, in order to solve the above-mentioned problem, development of a sanitary pad capable of eliminating wet conditions in a short time, effectively suppressing the propagation of germs, and removing an unpleasant odor has been demanded.

Particularly, when various kinds of functional particles are contained in order to solve the above-mentioned problems, such particles are dropped out, causing safety and hygienic deterioration, and research for solving such problems is also required.

In the present invention, the ferrite sintered body functions to neutralize the electromagnetic waves and the snakes, and at the same time, improve the blood circulation by the geomagnetism effect, thereby providing a beneficial effect to the human body.

The ferrite sintered body is prepared by mixing the above components and mixing 130 to 170 parts by weight of water, 2 to 4 parts by weight of dispersant and 2 to 3 parts by weight of binder to 100 parts by weight of the mixture and stirring with a stirring device such as a ball mill To make a mixture in the form of a viscous suspension (suspension).

The dispersing agent is a dispersing agent such as Ethoxylated Alkanolamide, which is used to uniformly disperse the particles of the mixed raw material in water and to be in a state of a good suspension (suspension).

The binder may be a binder such as an aqueous solution of polyvinyl alcohol to facilitate the granulation of the ferrite by increasing the binding force between the raw material particles during the granulation operation of the ferrite composition, do.

Next, the suspension mixture is spray dried and granulated. Specifically, the suspension prepared above is sprayed through a nozzle in a certain container, sprayed into a hot air-conditioned housing, or sprayed at a high pressure in the atmosphere, so that the suspension of the ferrite raw material is agglomerated and agglomerated due to the binder.

Next, the granular ferrite raw material is heated at a temperature of 1,000 to 1,400 ° C. for 3 to 8 hours through a method such as in-furnace heating to calcine the ferrite sintered body. At this time, the impurities such as the dispersing agent or the binder remaining in the ferrite raw material are removed.

Next, the ferrite sintered body is pulverized into powders using a conventional grinding apparatus to prepare a final ferrite sintered body.

In this case, the average particle size of the ferrite sintered body may be 50 μm to 1,000 μm, and preferably 100 μm to 500 μm.

In the present invention, when the conventional binder is used, the binder performs the function of eliminating the problem of causing hygienic and safety problems because the ferrite sintered body and the zeolite fixed to the functional patch easily fall off. The binder has a special composition to firmly fix the fine particles contained in the functional patch.

In particular, when the functional particles are fixed to the nonwoven fabric substrate, it is not easy to firmly fix the nonwoven fabric to the rough surface of the nonwoven fabric with the conventional binder. Therefore, a binder having such excellent adhesion strength is required.

The binder preferably further comprises polymerizing 40 to 50 mol% of acrylonitrile polymerization units, 20 to 30 mol% of acrylamide polymerization units and 20 to 40 mol% of acrylic acid or methacrylic acid-derived polymerization units, And 20 to 30 parts by weight of polypodamine relative to 100 parts by weight of the polymer.

The polymerization unit of acrylonitrile in the binder is acrylonitrile; The acrylamide polymerization unit is acrylamide; The polymerization unit derived from acrylic acid or methacrylic acid is preferably methacrylic acid.

In the present invention, the ceramic sintered body performs a far-infrared radiation effect and a function to realize an antibacterial and deodorizing effect.

The ceramic sintered body is prepared by mixing the above components and mixing 130 to 170 parts by weight of water, 2 to 4 parts by weight of dispersant and 2 to 3 parts by weight of binder with respect to 100 parts by weight of the mixture and stirring with a stirring device such as a ball mill To make a mixture in the form of a viscous suspension.

The dispersing agent is a dispersing agent such as Ethoxylated Alkanolamide, which is used to uniformly disperse the ceramic particles of the mixed raw material in water to be in a good suspension state.

The binder may be a binder such as an aqueous solution of polyvinyl alcohol to facilitate the granulation of the ceramic particles by increasing the binding force between the respective raw materials during the granulating operation of the ceramic particles to be performed in the future use.

Next, the suspension mixture is spray dried and granulated. Specifically, the suspension prepared above is injected into a housing of a hot air condition by injecting the suspension through a nozzle, or sprayed at high pressure in the air, so that the suspension of the ceramic material is agglomerated and agglomerated due to the binder.

Next, the granular ceramic raw material is heated at a temperature of 1,000 to 1,400 ° C for 3 to 8 hours through a method such as in-furnace heating to sinter the ceramic sintered body. At this time, the impurities such as the dispersing agent or the binder remaining in the ceramic raw material are removed.

Next, the ceramic sintered body is pulverized into powders using a conventional grinding apparatus to produce a final ceramic sintered body.

In this case, the average grain size of the ceramic sintered body may be 50 탆 to 1,000 탆, and preferably 100 탆 to 500 탆.

In the present invention, the functional powder can be applied to a substrate such as a nonwoven fabric by a known printing method. At this time, a natural mordant is mixed and subjected to a liquefaction process. The mordant is added so that the patterns and patterns to be printed are not blurred, but are cohered and printed clearly. In the present invention, natural mordants such as apple juice, omija juice, bark, vegetable tannin and the like can be used.

Since the specific technique of printing the functional mixture liquid such as the present invention on the fabric including the nonwoven fabric is a well-known technique, a detailed description of the specific process related to the printing method will be omitted.
