Description

BODY SECRETION ABSORBENT PRODUCT FOR WOME CAN BE CHANGE OF COLOR OF MENSTRUATION BLOOD}

The present invention relates to a bodily fluid absorbent product, and more particularly, by including a dyeing material for discoloring and coloring the physiological blood contained in the bodily fluid, thereby preventing the absorbed physiological blood from changing to a dark red color and discoloring to a preferred color. The present invention relates to a body fluid absorbent product capable of discoloring menstrual blood, which may prevent a user from having depression, psychological anxiety, and unsanitary feeling, and improve activity disorder.

Examples of absorbent products that absorb body fluids, including menstrual blood, vaginal discharge, and urine, are examples of sanitary napkins used by women. The sanitary napkin is worn in the form attached to underwear (panties, etc.) to absorb / retain the secreted body fluid from the body to prevent the body and clothing from being soiled.

Generally, sanitary napkins include a liquid permeable body contact sheet, an absorber and a liquid impermeable sheet. The body contact sheet is mainly composed of a hydrophilic nonwoven or woven fabric to be in contact with the body. The absorbent body is disposed between the body contact sheet and the liquid impermeable sheet (cloth contact sheet) to absorb and retain the body fluid that has passed through the body contact sheet. Such absorbers are mainly composed of fluffy pulp, superabsorbent resin and the like. The liquid impermeable sheet prevents the clothing from being soiled by blocking leakage of body fluid absorbed / retained in the absorbent to the outside, which may be in contact with the clothing. Such a liquid impermeable sheet mainly consists of a hydrophobic nonwoven fabric, a woven fabric, a synthetic film, or the like.

Menstrual periods are very uncomfortable for women. Most women feel depressed during menstruation. Sanitary napkins usually have a white or light color. Conventional sanitary napkins can provide a clean appearance due to this color. However, conventional sanitary napkins do not reduce or change the depressed mood of a woman during menstruation. Accordingly, a technique has been attempted to give a sanitary napkin a color or various pattern patterns to reduce depression and poor condition during menstrual periods and to switch to a refreshing and active mood.

For example, Japanese Utility Model Registration No. 3021237 (Prior Document 1) gives a sanitary napkin a color (or pattern) similar to the color (or pattern) of underwear so that others cannot recognize the wearing of the sanitary napkin from the outside. Sanitary napkins are presented. In addition, Korean Patent Registration No. 702821 (Previous Document 2) proposes an absorbent product intended to reduce a user's depressed mood by printing a graphic of an aesthetic image on the surface of a body contact sheet.

In addition, European Patent EP 1108405 (Prior Document 3) and Korean Laid-Open Patent Publication No. 2003-0061358 (Prior Document 4) give the same or similar color as the color of the underwear, so that when attached to the underwear, the eyes are less noticeable Absorbent products are proposed to conceal blood secretion.

However, absorbent products (physiological napkins, etc.) according to the prior art including the above-mentioned literatures are given a color or graphic (aesthetic image) as described above, thereby concealing the wearing of the sanitary napkin or reducing the depressed mood during the menstrual period through the aesthetic image. However, this method does not substantially resolve depression, psychological anxiety, unsanitary or active disorders that occur during menstrual periods.

Hemoglobin is found in red blood cells, and iron is contained in the nucleus of hemoglobin. Blood is reddish by these iron components. At this time, the blood (physiological blood) secreted (exhausted) from the body is oxidized to turn dark red (dark red). In fact, the majority of women complain of depression, psychological anxiety and unsanitary feelings due to the color of menstrual blood itself, that is, dark red blood, and suffer from active disorders.

As described above, the conventional technology imparts color or graphics to the absorbent product (physiological napkin, etc.) itself, and the conventional absorbent product (physiological napkin, etc.) is changed to dark red color by the secreted blood (physiological blood). There is a problem that makes you feel depressed or psychological anxiety and unsanitary, and suffer from active disorders.

The body fluid discoloration sheet 40 is composed of a non-woven fabric or woven fabric made of synthetic fibers or natural fibers, such as a base material, a gel or liquid composition containing a dyeing material 45 is applied to the surface of the base material Alternatively, the powdery dye material 45 may be dispersed in the base substrate.

The dyeing material 45 is included in the present invention as long as it prevents the physiological blood of the body fluid secreted from the body from changing to dark red (dark red), and preferably discolors to a preferred color. Specifically, the dyeing material 45 may be discolored to a color sufficient to recognize cleanliness among women, for example, a light green, yellow, blue, and sky blue. The dyeing material 45 may be used as long as it changes color to a color other than dark red (dark red).

The dyeing material 45 is a color change of physiological blood, and can be used a chemical dye (pigment), which is harmless to the human body, but preferably a powder concentrated with a natural dye (pigment) extracted from a natural material (vegetable or animal material) Can be used. Such natural dyes (pigments) can be used by taking natural substances and extracting them immediately or by powdering the extracted extract after fermentation for a long time (more than 6 months). For example, the natural dyes (pigments) are gardenia, yellow wall, yulpi, purple, sesame, wood, safflower, turmeric, lump, mulberry, gall, plum, plum, camphor, cherry, apricot, persimmon, oak, Powders of pigment concentrates extracted from one or more natural plants selected from black tea, pomegranate, cloves, schisandra, koji, rhubarb, fingerlings and coltsfoot can be used. In addition, the dye may be selected from biochemical synthetics. In this case, the biochemical synthetic material includes a luminescent function as well as a function of discoloring physiological blood. For example, the biochemical synthetic material may be usefully used such as luminol. In addition, the dye may include both natural dyes (pigments) and biochemical synthetic materials as described above.

In addition, the dyeing material 45 preferably includes a dye as described above, and a mordant for fixing the dye to physiological blood. In addition, the dyeing material 45 may further include a light emitting material. In this case, the mordant may be used as long as the dye (pigment) is fixed to menstrual blood so as not to fall off. In addition, the mordant includes a chemical reaction between the metal component of the mordant and the dye to develop and color in a color different from that of the dye. At this time, the mordant is to react with the dye to express the color, the dye may be expressed in different colors, depending on the type of mordant. Specifically, the physiological blood contained in the body fluid may be discolored or colored into a color different from the color of the dye itself by the dyeing material 45, or by the mordant used.

The mordant may be included in an amount of 0.1 to 30.0 parts by weight based on 100 parts by weight of a dye (preferably natural dyes such as gardenia, yellow wall, yulpi, licorice, and the like). At this time, if the content of the mordant is too small as less than 0.1 part by weight, it is not preferable because the effect (fixing of dye, etc.) due to its content is insignificant. In addition, when the content of the mordant is more than 30.0 parts by weight, the synergistic effect of the excessive content is not so great, and the content of the dye is relatively small, which is not preferable. Such mordant may be, for example, a compound containing tin, aluminum, copper, chromium and the like. More specifically, the mordant may be selected from tartaric acid, tartarate (sodium tinate, etc.), tin chloride, alum, aluminum acetate, copper acetate, copper sulfate, chromium acetate, sodium chromate, ammonium chromate and hydrogen peroxide.

In the above, the absorbent article of the present invention has been described taking the sanitary napkin 100 having a structure including the body contact sheet 10, the absorbent body 20 and the liquid impermeable sheet 30 as an example, but the absorbent article according to the present invention The body contact sheet 10 may have a structure in which it is excluded. Specifically, the absorbent product according to the present invention may be selected from the sanitary napkin 100 or the panty liner, etc., and the liquid formed on the absorber 20 and one side of the absorber 20 by contacting the body to absorb / retain the body fluid. It may have a structure including an impermeable sheet 30.

According to the present invention described above, a dyeing material for discoloring the body fluid (physiological blood) is included, unlike the conventionally imparted color to the absorbent product itself, to prevent the change of menstrual blood to dark red (dark red), By discoloring to a color other than dark red (dark red), the user does not have a feeling of depression, psychological anxiety and unsanitary, and improves and overcomes obstacles such as activity atrophy.
