The present invention relates to a disposable breast milk absorbent product, and more particularly, to a disposable breast milk absorbent product which can absorb and secrete the secreted breast milk by simply attaching it to the inside of a brassiere cup when breast milk secretion is high, such as a nursing mother. will be.

Bras made of rayon, cotton, polyester, nylon, etc. have the function to wrap women's breasts warmly.However, if the nursing mother is wearing a lot of breast milk, the bra does not absorb enough and the breast milk is not absorbed. As well as seeping out, there is a problem that causes discomfort to the people around them because of the unpleasant odors (Fishy smell) generated from breast milk.

The inventors of the present invention intensively studied how to easily process the secreted breast milk, as a result, the product that is modified so that the disposable absorbent product can be attached to the inside of the bra cup to use easily absorbed breast milk and absorbed breast milk The present invention was completed by finding out that it is very hygienic by not leaking to the outside.

The present invention is to provide a disposable breast milk absorbent product that can be easily attached to the inside of the bra cup to absorb the secreted breast milk.

Hereinafter, the present invention will be described in detail.

The present invention includes a liquid permeable topsheet, a fluffy pulp and a liquid impermeable backsheet as a basic component, and at least one component includes a superabsorbent resin and far-infrared radiation ceramics, the absorbing power of 0.5 g / cm ² or more, and the thickness thereof. To provide a disposable breast milk absorbent product of 12 ~ 2mm and area of 130 ~ 10cm ² .

Absorption capacity is the absorbed state of the disposable breast milk absorbent product (W ₁ ), which already knows the weight, is immersed in 0.9% NaCl solution for 10 minutes and then taken out of the solution, suspended in the air for 20 minutes to let the absorbed solution flow, and then absorbed. The weight of the disposable breast milk absorbent product of W ( ₂ ) is measured and the weight difference (W ₁ -W ₂ ) divided by the absorbent body area of the disposable breast milk absorbent product.

By inserting and inserting the disposable breast milk absorbent product of the present invention, not only the female breast milk can be absorbed cleanly, but also the far infrared radiating ceramics and the super absorbent resin are added together, so the unpleasant smell such as the fishy smell of breast milk. Odor generation can be suppressed and the effect is superior to the case of using far-infrared radiation ceramics and super absorbent polymer alone.

The superabsorbent resin used in the present invention is the same superabsorbent resin as used in ordinary disposable absorbent products such as disposable diapers, sanitary napkins, panty liners, etc., and can absorb water hundreds of times more than the weight of the resin itself. Unlike natural pulp, it has excellent water-retaining ability because it has a property of swelling and gelling. Examples thereof include polyacrylic acid salts, copolymers of isoprene and maleic acid salts, copolymers of starch and polyacrylates, copolymers of polyvinyl alcohol and polyacrylates, starch / polyacrylonitrile grafts, polyvinyl alcohols, Polyacrylamide-based, polyoxyethylene-based or carboxymethyl cellulose crosslinked products.

The superabsorbent polymer may be contained in the disposable breast milk absorbent product in various ways, but is preferably contained in the downy pulp layer.

Downy pulp is made of fluff by processing wood pulp and is a hydrophilic absorbent that acts to absorb secretions. Such fluffy pulp may be those used in conventional disposable absorbent products.

In the present invention, the liquid permeable top sheet is a known one used in a general absorbent article, and generally nonwoven is used most.

In addition, liquid impermeable back sheets are also known to be used in ordinary disposable absorbent products, and are generally used, for example, non-breathable waterproof films, breathable waterproof films, and biodegradable waterproof films or non-woven fabrics thereof. ).

Disposable breast milk absorbent product of the present invention may optionally include a tissue, an adhesive component (Hot melt, Glue, etc.) and a system for fixing to a bra or underwear as an auxiliary component in addition to the above basic components.

Far-infrared radiation ceramics is a non-metal inorganic material obtained by mixing two or more kinds of oxides of silicon, aluminum, sodium, potassium, calcium, iron and zirconium and mixing them with high-temperature heat treatment. It is known to emit far infrared rays. In the present invention, such far-infrared radiation ceramics are contained in at least one of the above components. There may be various methods of containing them, and some examples of such methods are as follows.

(1) Method to contain during the production of liquid permeable top sheet

(2) Method to contain at the time of manufacture of downy pulp

(3) Method to make it contain at the time of manufacture of superabsorbent polymer

(4) Method to contain at the time of tissue manufacture

(5) Method to be included in the manufacture of disposable breast milk absorbent product

Disposable breast milk absorbent products of the present invention should have an absorption of at least 0.5 g / cm ² . If the absorptivity is below the above, the secreted mother milk cannot be sufficiently absorbed.

In addition, the size of the product should be 12 ~ 2mm thick and 130 ~ 10cm ² wide. If the size is larger than the above, it is difficult and inconvenient to attach to the inside of the bra cup, and if the size is smaller than the above, breast milk may leak out.

The components can be combined in the same order as in conventional disposable diapers and the like. For example, as shown in FIG. 1, the absorbent body including the downy pulp 2 and the superabsorbent resin 3 is wrapped in a tissue 4 on the liquid permeable back sheet 1, and the liquid permeable top sheet 5 is placed thereon. Cover. Disposable breast milk absorbers may be shaped into any form that can be attached to the inside of the bra cup. For example, it can be made in the form of Figures 2a to 2d, it is attached to the inside of the bra cup as shown in Figure 3 is used.

Disposable breast milk absorbent products of the present invention can be manufactured similarly to the production equipment for disposable paper diapers. That is, the components move or disperse by placing the components of the above-mentioned disposable breast milk absorbent product in order on the moving belt with adhesive components (Hot-melt or Glue, etc.) or heat-sealing them. After cutting to prevent the final cutting (Cutting Machine) by cutting (Cutting Machine) to produce a disposable breast milk absorbent product.

Hereinafter, the present invention will be described in more detail with reference to the following examples.

That is, the less amount of backing, the person wearing the disposable breast milk absorbent product feels refreshed with a dry texture and is evaluated as an excellent disposable breast milk absorbent product.

Burial volume experiments were carried out as follows.

2 ml of breast milk was poured into the central portion of the disposable breast milk absorbent product. After 10 minutes, dry tissue (20g / m) measuring 10cm × 10cm (W). ) Was placed in the place where breast milk was poured and immediately placed a weight of 3.5 kg and a diameter of 14 cm for 30 seconds. The weight was removed and the tissue weight (W) was again measured to calculate the amount of backfilling as W-W.

On the other hand, the flow rate 120 g / m as a control example The same experiment was conducted for conventional bras woven from phosphorus polyester fibers.

[Smell Odor Test]

The degree of fishy smell was tested as follows.

5 ml of breast milk was poured into the central portion of the disposable breast milk absorbent product and then stored for 5 hours in a constant temperature and humidity bath at a temperature of 36 ° C. and a relative humidity of 80%. On the other hand, the flow rate 120 g / m as a control example The same experiment was conducted for conventional bras woven from phosphorus polyester fibers.

The treated product was subjected to sensory evaluation of the smell of fishy smell in healthy males aged 30 to 35 years, and then the relative value of the fishy smell was recorded on the basis of the control case of 100 and averaged.

Table 2 shows the results of the amount of back turing and the smell of fish that were tested above.

As shown in the results of Table 2, it can be seen that the disposable breast milk absorbent product according to the present invention is much superior to the conventional bra in a backing test in which the degree of breast milk does not leak out of the bra. In addition, it can be seen that the disposable breast milk absorbent product of the present invention has a superior fish odor suppressing effect than the conventional bra in the degree of fish smell smell test. In particular, as the amount of far-infrared radiation ceramics is increased, the occurrence of fishy smell is relatively reduced.
