The present invention relates to a hub polymer absorbent paper and a method for manufacturing the same, and more particularly, a hub polymer absorbent paper and a hub polymer absorbent paper including an antibacterial absorbent composition having deodorization, dehumidification, generation of anions and far infrared rays, and antibacterial action. It relates to a method for producing.

Generally, the absorbent resin used as an absorbent composition is used for absorbent articles, such as a paper diaper, a sanitary napkin, and a breast milk pad, using the absorbent performance. Such a water absorbent resin conventionally only absorbs water by capillary action, and also has low absorption power and easily discharges water when pressure is applied.

Hydrophilic polymers have been developed to solve this problem.

However, these materials are only characterized by the fact that they do not easily discharge water under pressure, the absorption power is only 20 to 30 times its own weight is not large enough to replace the conventionally used pulp. Subsequently, as a result of the study of materials having high absorbency, polymers having starch-based and polyacrylic acid-based compositions have been developed, and now they have been developed as reinforced absorbent polymers (SAP) which have further enhanced their functions.

Super absorbent polymers, such as reinforced absorbent polymers (SAP), are typically white powders and have the property of absorbing and moistening the gel instantaneously upon entering the water. Such a super absorbent polymer generally has an absorbent power of 100 g / g or more, and some super absorbent resins have an absorbent power of 1000 g / g. Looking at the properties of the various absorbent materials described above are shown in Table 1 below.

Absorbents using such superabsorbent polymers are excellent in the ability to absorb and retain urine, blood, body fluids, and the like, but do not have antibacterial function. Therefore, when the superabsorbent polymer absorbs urine, blood, and body fluids, organic matter contained in the absorbent liquid is decomposed by fungi or microorganisms, and the products generated by decomposition cause odor or skin irritation. There is this. Therefore, from the viewpoint of hygiene and safety, the emergence of a material that satisfies both the absorption function and the antibacterial function is required. In particular, in absorbent articles such as diapers used for infants, the elderly, and patients, which are resistant to drugs, the problem of odor and bacterial growth is very important.

In order to solve the above problems, there has been development of absorbent articles as follows.

Japanese Patent Application Laid-Open No. 59-179114 relates to an absorbent article using a mixture of an absorbent resin and zeolite, and Japanese Patent Laid-Open Publication No. 56-31425 for an absorbent article using a composition coated with an activated carbon absorbent resin. There is an arc.

However, such a composition could not obtain the odor prevention effect or the anti-corruption effect which is essential for application to an absorbent article.

That is, the absorbent resin and the zeolite mixture can adsorb the odor generated to some extent, but since both the absorbent resin and the zeolite do not have an antibacterial function, the decomposition and decay of organic substances by microorganisms and fungi cannot be suppressed, and thus the odor It cannot be prevented.

In addition, even in the case of the composition coated with the activated carbon absorbent resin, most of the odor can be removed, but the same result as in the case of the zeolite described above, the decomposition or decay of organic substances by microorganisms and fungi cannot be suppressed.

The present invention has been made to solve the above problems, an object of the present invention is to provide a polymer absorbent paper having an absorbent composition excellent in both absorbent performance and antibacterial function.

In particular, it is to provide a polymer absorbent paper including an antimicrobial absorbent composition capable of absorbing urine, blood, body fluids and the like.

In order to achieve the above technical problem, the absorbent composition has a blending ratio of about 50% by weight of chrysanthemum, 30% by weight or less of rosemary, and 20% by weight of starch, so that the body fluid can be quickly absorbed and have an odor and antibacterial action. Eggplant is characterized by consisting of a superabsorbent resin that can have a strong powder and the herbal powder.

In addition, the herbal powder (composition) is placed inside the absorbent article such as a diaper in a mixture powder (herb powder + super absorbent polymer) mixed with a super absorbent polymer and 50% by weight.

However, the herbal powder can not exceed 60% by weight, therefore, the super absorbent polymer is mixed at a ratio of 40% by weight or more.

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

Functional composition according to the present invention contains about 50% by weight of chrysanthemum flowers, 30% by weight or less of rosemary, 20% by weight or less of starch. These compositions are all in powder form with microparticles.

Hereinafter, the effects of each component will be examined, and a method for preparing a herb powder containing each component, a method for preparing a mixed powder in which a herbal powder and a super absorbent polymer are combined, and a method for preparing a polymer absorbent paper (SAP sheet) including a mixed powder will be described. I will explain in order.

Effect of Each Ingredient>

(1) Chrysanthemum flowers

Chrysanthemum flowers have a clear heat detoxification effect, enhances the anti-inflammatory effect and capillary resistance, and has been known to have anti-inflammatory effects. Experimentally, antipyretic and blood pressure lowering action, cardiac blood vessel expansion, fungal action, and antiviral action were found. Abundance, dizziness and pain in the head due to fever, eyes open and tears come out of the eyes, bone media pain, carbuncle, spear, high blood pressure, etc. is used.

In particular, the chrysanthemum flower contains essential oils such as cusanthenone and chrysamine, which are adenine, prin, betaine, and yellow pigment. Eliminates Consent of sensation and clinical application records also have pharmacological action of decongestion, and it is effective in preventing hypertension by acting as a blood pressure lowering effect that expands peripheral blood vessels and inhibits vascular movement centers.

(2) rosemary

It contains various ingredients such as menthol and mint, and shows a high antibacterial effect by the synergistic action of these ingredients. These effects are known to be due to the fact that ingredients such as menthol and mint enter the cells of fungi or microorganisms and inhibit the physiological activity of amino acids. In addition, rosemary is a type of herb (Herb), and also acts as a natural spice in addition to the antimicrobial effect, and when it comes in contact with the human body, it smells fragrant and refreshes the mood.

However, in the present invention, the weight ratio of rosemary is 30% by weight or less, but the reason why it is less than the chrysanthemum flower is that the fragrance of rosemary is too strong because it may cause discomfort and headache rather than refreshing feeling when it is included too much. to be.

(3) starch

The starch used with chrysanthemum flowers and rosemary allows the chrysanthemum flowers and rosemary to be evenly applied in a polymer sheet (SAP sheet). In other words, if the chrysanthemum flower and rosemary are finely powdered, they may stick together or agglomerate after being injected from the ejector.

This starch has no effect on absorbency and antibacterial effect, so it is desirable to minimize the specific gravity. However, in order to make a good herb powder by mixing chrysanthemum flowers and rosemary, the starch weight should be 20% by weight. It was confirmed through repeated experiments. There are many kinds of starch, but it is preferable to use corn starch, which is relatively easy and inexpensive.

Manufacturing of Herb Powders>

The preparation of the herbal powder is in the following order as shown in FIG.

(1) Material preparation process of preparing dried chrysanthemum flowers and rosemary and preparing starch (corn starch)

(2) Chrysanthemum flower crushing process of crushing chrysanthemum flower by crusher and filtering by standard mesh to obtain a certain size powder.

(3) Rosemary grinding process of crushing rosemary with a pulverizer and filtering it with a standard mesh to obtain a powder of a certain size.

(4) The mixing process of chrysanthemum flower, rosemary, and starch which mixes starch with the raw material of (2)-(3).

(5) A kneading step of making a dough having a viscosity by adding distilled water to about 30% by weight to the mixture of (4).

(6) A drying step of drying the dough of (5) in a hot air dryer at a temperature of 40 degrees for about one week.

At this time, when drying, the herbal powder should be sufficiently dried so that the residual moisture is less than 8% by weight. If the residual moisture exceeds 8% by weight, it is not mixed properly when added together with the granular superabsorbent resin. Iii) The quality of the finished product is poor, such as color change because it is not evenly distributed on the pulp surface.

In addition, the hot air dryer used as a drying apparatus is not limited thereto, and other conventionally known apparatuses may also be used. For example, a fluidized bed dryer, a belt dryer, a drum dryer, a Nauta dryer, a paddle dryer, a rotary kiln type dryer, and an infrared dryer are mentioned.

(7) A straining process for preparing a herb powder by pulverizing the dried product of (6) with a pulverizer, filtering it with a standard mesh, and collecting a substance having a size of 500 micrometers or less.

The pulverizer may use a variety of devices, such as a hammer mill, a pin mill, a roll mill, parfaitizer, a feather mill, a cutter mill.

Preparation of Mixed Powder>

A mixer is used to mix the herbal powder and superabsorbent resin from the above process by 50% by weight. The mixed powder enters between the pulp and the pulp to form a polymer absorbent sheet (SAP sheet). Such a herb powder can be adjusted depending on the situation, but should not exceed 60% by weight. The reason is that if the herbal powder exceeds 60% by weight, the superabsorbent resin and the herbal powder are not evenly mixed.

Manufacturing of Herbal Polymer Absorbent Sheets>

Hub polymer absorbent paper (SAP sheet) is prepared according to the process as shown in Figure 4, the detailed description is as follows.

(1) Tissue unwinding process to remove tissue from unrolling roll

(2) a fluff pulp input process for applying a certain amount of fluff pulp to tissues;

(3) mixing powder input process for applying the mixed powder on the fluff pulp;

(4) a fluff pulp feeding step of applying fluff pulp again on the mixed powder;

(5) the tissue unwinding process of unwinding the tissue from the unwinding roll on the fluff pulp;

(6) compression process using a roll to apply heat and pressure;

(7) winding and cutting process of taking out the compressed material and cutting it to the width required by the consumer;

(8) It consists of a packaging process for individually packaging finished products.

Through the eight-step process described above, the hub polymer absorbent paper (SAP sheet) is automatically manufactured.

The mixed powder input process of the hub polymer absorbent paper replaces the superabsorbent polymer feed process of the conventional polymer absorbent paper shown in FIG. 1. Such a super absorbent polymer injection process can be easily converted to a simple operation to produce a hub polymer absorbent paper having an antibacterial effect.

The cross section of the hub polymer absorbent paper (SAP sheet) produced by such a process is shown in FIG. Fluffy pulp (2) is located between the tissue (1) and the tissue (1) in the hub polymer absorbent paper (SAP sheet), the superabsorbent resin (3) and the herbal powder (4) between the fluff pulp (2) ) Are evenly distributed.

In contrast, in the conventional polymer sheet (SAP sheet), only the superabsorbent resin 3 is distributed between the fluff pulp 2, as shown in FIG.

That is, the conventional polymer sheet (SAP sheet) is placed only between the pulp (2) and the pulp (2) by emphasizing only the absorbent performance, whereas the herbal polymer absorbent sheet (SAP sheet) of the present invention is a super absorbent resin ( 3) and the herb powder 4 are evenly positioned, so that an absorbent article having an antibacterial effect can be obtained without degrading the absorbent performance.

The new SAP sheet manufacturing method simply converts the superabsorbent resin input process into the mixed powder input process in a conventional apparatus, and thus, it is possible to manufacture absorbents that can be easily sterilized without additional equipment. Do.

The function and operation of the present invention of the above-described configuration will be described.

Herbal SAP sheets used in absorbent articles such as diapers or sanitary napkins are sandwiched between the sheaths. Therefore, once urine, menstrual blood, or vaginal discharge is discharged from the human body, it is primarily absorbed from the outer skin of the absorbent material, and secondly, the herbal polymer absorbent paper (SAP sheet) absorbs urine or menstrual blood.

Organics such as urine or menstrual blood absorbed in the superabsorbent resin of the herbal polymer's SAP sheet usually increase the propagation of bacteria related to biological activities, and also cause an unpleasant odor due to decomposition products generated in this process. do. These unpleasant odors and propagated bacteria are removed by the potent antibacterial activity of chrysanthemums and rosemary.

Therefore, in the superabsorbent resin, the excreta is strongly absorbed, and the absorbed excrement is absorbed and antibacterial at the same time as the growth of bacteria is suppressed by the chrysanthemum flower and rosemary adjacent to the superabsorbent resin, and the propagated bacteria are sterilized. .

In addition, the rosemary contained in the herbal powder neutralizes the unpleasant odor generated from various excrements due to the inherent aroma, thereby making the wearer feel refreshed and improving the emotional and functional aspects.

Effects of the above-described configuration on the hub polymer absorbent paper (SAP sheet) according to the present invention are as follows.

First, it is possible to develop an absorbent article capable of realizing the antibacterial function by the chrysanthemum flower and rosemary as well as the absorption function by the super absorbent polymer.

Second, the organic matter contained in urine, blood, and body fluids absorbed in the absorbent resin can be suppressed from being decayed by fungi, microorganisms, bacteria, and the like.

Third, as a result of suppression of corruption, the occurrence of odor can be reduced. In addition, even if a slight odor occurs it is neutralized by the rosemary, so that the user can feel comfortable even for a long time use.

Fourth, the antibacterial function can be imparted to the absorbent article by the chrysanthemum flower and rosemary, thereby reducing the occurrence of skin irritation or dermatitis caused by various bacteria. In addition, when various bacteria decompose organic matters, the debris is permeated into various gaps, and accordingly, the absorbing performance may be reduced. The performance of can also be improved.

Fifth, it is possible to produce a functional polymer absorbent sheet (SAP sheet) capable of antibacterial effect while maintaining the same manufacturing process of the conventional polymer sheet (SAP sheet), it has an excellent effect on the price competitiveness.
