Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

The present invention microencapsulates a health functional substance such as vitamin E or medicinal natural oil using the wall material 10 and an emulsifier, and sprays or dips it on a disposable absorbent product such as a diaper. As the microcapsules are broken when the product according to the present invention is worn, vitamin E or medicinal natural oil penetrates into the skin, thereby improving the health of sensitive skin and preventing skin rashes and sores.

In general, absorbent products such as disposable diapers are products that absorb excretion such as urine and stool excreted by physiological effects. The absorption and absorption rate of excreta are the most important, but the improvement of people's life and the friction between diapers and skin In addition to preventing skin rashes and sores, the company also considers improving health.

When wearing a functional diaper or the like according to the present invention, since a small amount of vitamin E or medicinal natural oil continuously penetrates through the skin, there is an effect of promoting health.

Looking at the properties and efficacy of vitamin E, the microcapsules wick material 20 of the present invention are as follows.

Property

Generally called tocopherol acetate and natural vitamin E-active substances present in nature include eight types of four types of tocopherols (α, β, γ, δ) and four types of tocotorienol (α, β, γ, δ) Known, these are collectively called vitamin E. The biological activity is the strongest α-tocopherol, in the narrow sense vitamin E refers to α-tocopherol. The mechanism of action of vitamin E is still not clear, but antioxidant activity is known. Safe to heat and acid and unstable to alkali Since it is insoluble in water, there is no loss during cooking, but it is destroyed when it comes into contact with rancid fat or iron.

Effect of skin penetration

It improves the hydration of the stratum corneum of the skin, promotes healing of wounds and leaves no scars of burns. Unsaturated fatty acids, vitamin A, beta-carotene, sex hormones, etc. have antioxidant activity to prevent oxidation. Lowers blood cholesterol levels. By inhibiting abnormal aggregation of platelets, the formation of thrombi is prevented. Prevent and treat myasthenia gravis and dystrophy. Along with vitamin C and selenium, it is a powerful antioxidant. Significantly reduce the body's oxygen needs. In addition, there is a function of maintaining and protecting intracellular membranes, increasing enzyme activity in the skin, maintaining soft skin, and improving skin stability.

Effect by ingestion

Anti-fatigue, promote blood flow, prevent blood clot, lower cholesterol level, strengthen sexual function, 諍 lobe 穗  cardiac function, antioxidant activity, inhibits the causative agents of arteriosclerosis, cancer, aging, inhibits the formation of oxidized lipids of cell membranes, protects blood vessels, Long life of red blood cells, muscle strengthening, angina prevention, reproductive function and abortion and infertility improvement.

On the other hand, look at the health function performance of the medicinal natural oil used in the present invention.

Aloe oil is an oil type essence that is not sticky at all, and it is good for moisturizing medium, oily and acne skin.

Olive oil is a pure vegetable oil, which has better skin penetration and dissolving power than mineral oil, and it is moisturizing and is absorbed into the skin without stickiness and shine. Olive oil contains a lot of vitamin E and ceramide, which are found in retinol cosmetics, so it has a high affinity for skin and strong absorption, which helps to relax the skin and prevent skin aging. Applying a drop or two of olive oil around your eyes before going to bed can help you feel moist and taut the next day.

Sweet almond oil is rich in minerals and vitamins, which is good for dry, premature aging and sensitive skin. It is also effective for pruritus caused by conditions such as eczema.

Avocado oil is good for penetrating and aging skin due to its high penetration and is effective for eczema and wound healing.

Wheat germ oil is good for aging skin with dry and dead skin cells and is effective for eczema, dryness and burns.

Mugwort essential oil has a characteristic scent, itching, antibacterial, antiviral, antipyretic effect, smooth blood circulation to clean skin, strengthen immune function and soften bowel movement.

In the preparation of the microcapsules of the present invention, an emulsion is prepared using an anionic surfactant, and the solution is diluted with vitamin E or jojoba oil diluted at a predetermined ratio, and then mixed with a homomixer at a speed of 10,000 to 13,000 rpm at 3 to 5 rpm. Stirring for about minutes to prepare a micronized emulsion to a certain size.

Prepare a prepolymer solution by mixing urea or melamine, formaldehyde and water in a certain ratio (preferably using melamine rather than urea in view of the durability of the resin), adjusting the pH to neutral, and stirring at an appropriate temperature. . After adding 0.1-5% of weakly acidic additives (acetic acid, formic acid, oleic acid, etc.) to the prepolymerized solution and the micronized emulsion, the mixture is stirred at an appropriate temperature for 100 to 300 minutes. After cooling to room temperature, a certain amount of ammonia is added to remove residual formaldehyde and stirred for 1 hour or more.

The microcapsules made as above have a structure as shown in FIG. 1. As a result of the test, the addition ratio of Johnson & Johnson powder flavor oil used as an additive of the wicking material 20 was 1 to 10% by weight. If the dilution ratio of Johnson & Johnson powder fragrance oil is too high, there is a problem that the degree of fragrance is high and the ratio of vitamin E or medicinal natural oil used as a wick is too low to be effective, and the dilution ratio of Johnson & Johnson powder fragrance oil is too high. At low levels, the degree of smell was minimal.

Vitamin E and jojoba oil used about 50% dilution with other medicinal natural oils. When only the stock solution was used, the microcapsules did not have good results. It is preferable to dilute to 50% in terms of yield and size control.

The thickness of the urea or melamine-formaldehyde layer can be adjusted as the ratio of emulsion and prepolymer solution. If the resin layer is too thin, the durability is inferior. If the resin layer is too thick, there is no bursting of the capsule due to friction, so the effect of vitamin E or jojoba oil on the human body cannot be expected.

In the manufacture of non-woven fabrics or absorbent cores (2, 8) for functional diapers, the above-mentioned microcapsules are mixed with a binder (urethane resin, acrylic resin, etc.), a softening agent and water in a predetermined ratio, and when spraying, Only the part which contacts is sprayed, and when it is an immersion method, this mixed liquid is put into an immersion tank and it keeps at 40-45 degreeC. The temperature of 40 to 45 DEG C is selected because the test results show that the temperature of the microcapsules has the best penetration and dispersion of the microcapsules or the absorbent cores (2, 8). Maintaining this state, the dipping process is performed, and the dehydration process is performed to obtain an appropriate pickup rate.

At this time, when the spray method is used, the adhesion degree of the microcapsules is about 10 to 20 g / m2, and when the immersion method is used, the pick-up rate is adjusted by dehydration process according to the component and thickness of the nonwoven fabric or absorbent core (2, 8). Is the most important. After this process, it is dried for a few minutes at a constant temperature, and then hardened for 1 to 5 minutes at 150 to 160 ℃ using a tenter. If the curing temperature is too low, the bonding force between the microcapsules and the nonwoven fabric or absorbent cores (2, 8) is reduced. If the curing temperature is too high, the microcapsules have poor durability, or the original properties of the nonwoven fabric or the absorbent cores (2, 8) are deteriorated. Can be.

The nonwoven fabric thus prepared can be applied to the top sheets 3 and 5, which are the parts in direct contact with the skin of the diaper, or to the barrier cuff 7 and the back sheet 9, if necessary.

In addition, the absorbent cores 2 and 8 coated with the microcapsules may be applied to diapers and the like. The absorbent cores 2, 8 are typically composed of a composite of superabsorbent resin and fluff pulp.

The microcapsule-coated nonwoven fabric or absorbent core (2, 8) is applied to the diaper, and the microcapsules are burst by friction each time they move, and the subtle scent of Johnson & Johnson powder and vitamin E or medicinal natural oil are applied to the skin. Direct contact allows carrying out the objects of the present invention.

Hereinafter, the present invention will be described in detail with reference to specific examples. However, the scope of the present invention is not limited by the following examples.

Preparation of Microcapsules

Preparation Example 1

First step: preparation of surfactant solution

Water and styrene maleic hydride are mixed to prepare a weakly acidic surfactant solution.

Second process: manufacturing wick material

After mixing 178 g of vitamin E and 178 g of jojoba oil, 18 g of Johnson & Johnson powdered oil is added to prepare a wick.

Third Step: Emulsion Preparation

After mixing 554 g of the surfactant solution and 374 g of the wick material, a micronized emulsion was prepared by stirring at a speed of 12,000 to 13,000 rpm for about 4 minutes using a homomixer at 35 to 40 ° C. The prepared emulsion obtained an average particle size of 3.56 ㎛ through a particle size meter.

Fourth Step: Preparation of Formaldehyde Solution for Prepolymerization

56 g of water and 62 g of formaldehyde (35 to 37%) are mixed and neutralized using a caustic soda solution.

5th Step: Preparation of Prepolymerization Solution

22.4 g of melamine and 119 g of the formaldehyde solution prepared in the fourth step were mixed, stirred at 55 to 65 ° C. for 30 minutes, and cooled to 35 to 40 ° C. to prepare a transparent prepolymer solution.

6th Step: Preparation of Microcapsules

After mixing 141.4 g of the prepolymer solution and 18 g of acetic acid and the emulsion prepared in the third step, the mixture is stirred at 55 to 65 ° C. for 150 minutes at a speed of 300 to 400 rpm. Thereafter, after cooling to room temperature, 10 g of ammonia solution (28%) was added to remove residual formaldehyde, and stirred for 1 hour or more to prepare vitamin E and jojoba oil-containing microcapsules. The microcapsules thus obtained had an average particle size of 3.59 μm through a particle size analyzer, and had a solid content of about 40%.

Preparation Example 2

In Preparation Example 1 was prepared in the same manner as in Preparation Example 1 except that the mixing ratio of the wick material (Vitamin E 356g, Johnson and Johnson powder flavor oil 18g) was adjusted.

Preparation Example 3

In Preparation Example 1 was prepared in the same manner as in Preparation Example 1 except that the jojoba oil in the wick material was adjusted to aloe oil.

Preparation Example 4

In Preparation Example 1 was prepared in the same manner as in Preparation Example 1 except that the jojoba oil in the wick material was adjusted to olive oil.

Preparation Example 5

In Preparation Example 1 was prepared in the same manner as in Preparation Example 1 except that the jojoba oil in the wick material was adjusted to sweet almond oil.

Preparation Example 6

In Preparation Example 1 was prepared in the same manner as in Preparation Example 1 except that the jojoba oil in the wick material was adjusted to avocado oil.

Preparation Example 7

In Preparation Example 1 was prepared in the same manner as in Preparation Example 1 except that the jojoba oil in the wick material was adjusted to wheat germ oil.

Preparation Example 8

In Preparation Example 1 was prepared in the same manner as in Preparation Example 1 except that the mixing ratio (4g) of Johnson and Johnson powder oil in the wick material was adjusted.

Preparation Example 9

In Preparation Example 1 was prepared in the same manner as in Preparation Example 1 except for adjusting the mixing ratio (37g) of Johnson and Johnson powder oil in the wick material.

As a result of the production examples, the particle size distribution after emulsification was very poor and the microcapsules were prepared when the mixing ratio of the wick material was adjusted to 356 g of vitamin E and 18 g of Johnson & Johnson powdered oil as in Preparation Example 2. Many problems occurred in stability even after manufacture. Although not shown in the preparation example, a similar problem occurred when preparing jojoba oil instead of vitamin E as in Preparation Example 2. Several experiments have shown that vitamin E and jojoba oil do not exceed 50% by weight of the wick.

The microcapsules prepared as in Preparation Examples 3 to 7 using aloe oil, olive oil, sweet almond oil, avocado oil, wheat germ oil, etc. in medicinal natural oils were very stable. In addition, although not shown in the preparation examples, even in the case of emulsification of aloe oil, olive oil, sweet almond oil, avocado oil, wheat germ oil, etc. in medicinal natural oils, the particle size distribution is good even during emulsification. It was very stable even after preparation of microcapsules.

As in Preparation Example 8 and Preparation Example 9, the microcapsules prepared by adjusting the ratio of Johnson & Johnson powder flavor oil to 1% by weight (4 g) and 10% by weight (37 g) of the wick material had no problems in stability. When the microcapsules prepared as in Preparation Example 8 were applied to a diaper, the degree of divergence was very small. The microcapsules were used a lot to increase the amount of fragrance, but they had a lot of influence on the original use of the single mask or diaper. On the contrary, when the microcapsules prepared as in Preparation Example 9 were applied to the diaper, the degree of aroma emission was very strong. The microcapsules were used less to reduce the amount of perfume, but the health-improving effect of the present invention was reduced. The ratio of the oil of Johnson & Johnson powder flavor of the wick material is preferably about 5% by weight of the wick material.

<Production of Nonwoven Fabric for Health Functional Diaper>

Example 1

Step 1: Spray Solution Preparation

After mixing 400 g of the microcapsules prepared in Example 1, 100 g of polyurethane binder, and 2,000 g of water, the solution was placed in a spray gun connected to a compressor.

Second Process: Spraying

When the solution prepared in the first step is dried, the degree of adhesion of the microcapsules is 10 to 20 g / m 2, and then sprayed at a predetermined ratio on the upper sheet nonwoven fabric which is in contact with the skin during fabrication of the diaper, and then at 100 to 120 ° C. After drying for 1 to 2 minutes, the top sheet for diapers with a microcapsule is prepared through a curing process for 1 to 2 minutes under a tenter condition of 150 to 160 ° C.

Example 2

In Example 1, the mixed solution was adjusted to 100 g of microcapsules, 25 g of polyurethane binder, and 2,375 g of water, and immersed instead of the spray method. It manufactured like Example 1 except having adjusted to.

Example 3

Except for using the microcapsules made in Preparation Example 3 was prepared in the same manner as in Example 1.

Example 4

Except for using the microcapsules made in Preparation Example 4 was prepared in the same manner as in Example 1.

Example 5

Except for using the microcapsules made in Preparation Example 5 was prepared in the same manner as in Example 1.

Example 6

Except for using the microcapsules made in Preparation Example 6 was prepared in the same manner as in Example 1.

Example 7

Preparation was carried out in the same manner as in Example 1 except that the microcapsules made in Preparation Example 7 were used.

Except for using the microcapsules made in Preparation Example 8 was prepared in the same manner as in Example 1.

Example 9

Preparation was carried out in the same manner as in Example 1 except that the microcapsules made in Preparation Example 9 were used.

In view of the above embodiments, the nonwoven fabric for diapers uses a spray coating method rather than a immersion coating method which is commonly used, and spray coating is preferable because immersion coating may lower the liquid permeability of the upper sheet of the diaper. In addition, in order to improve the health, which is the object of the present invention, it is much more efficient to treat only the part in contact with the skin in view of the original use of the monovalent cotton or diaper.

As a result of producing a functional diaper as shown in Fig. 2, 3 using a non-woven fabric made as in Examples 1 to 9, the superiority of the product was found.
