Sterilization and deodorization disposable sanitary napkins {Sterilzational and deodorizational disposable sanitary pad}

The present invention relates to a sterile deodorizing disposable sanitary napkin. More particularly, the present invention relates to a copper fiber-containing disposable sanitary napkin which is known to have excellent sterilizing effect and excellent deodorizing performance.

Common disposable sanitary napkins include sanitary napkins, panty liners, disposable diapers and tampons that absorb urine, menstrual secretions or vaginal secretions. An absorbent sheet containing an inner skin, which is a liquid permeable cover, and a super absorption polymer laminated on the bottom of the cover to absorb secretions, and a liquid impermeable cover that surrounds one side of the absorbent sheet and prevents secretions from leaking to the outside. It is composed of an outer shell to absorb secretions and prevent them from leaking or flowing.

Disposable sanitary napkins such as odors are produced when body fluids stay in the absorbent layer for a long time, and ammonia, hydrogen sulfide, and mercaptans are generated from physiological substances, which can be a source of odor and skin irritation, and cause colds, colds, and itching to be infected through the vulva. It can also cause various gynecological diseases.

In Korean Patent Application Publication No. 00-5167, which was previously filed, a method of manufacturing a disposable sanitary napkin having a sterilizing effect has been known by applying a herbal medicine solution. However, the herbal medicine solution as described above has a disadvantage in that the manufacturing method is complicated and material costs are consumed.

First, as copper is well known, it is a metal with a solid history and tradition that has been used in everyday life since the birth of mankind about six thousand BC. It is known to have a bactericidal effect. This trace metal action was known in 1893 when a botanist named Negeri Li discovered the action of 10 million copper ions to kill algae. Doing. As a product applying the copper trace metal action, for example, shoes insoles for removing foot odors, etc. are used for purifying air in humidifiers and air purifiers.

Copper used in the present invention was used to refine copper ore, which is a sulfur compound such as brass or pyrite. First, an oxygen-free copper wire having a diameter of 10 (mm) to 20 (mm) was drawn to make a copper fiber, and then the copper fiber was stretched again to finally taper up to a diameter of 30 to 40 µm to prepare ultrafine copper fiber. The prepared ultra-fine copper fiber can maximize the surface area in contact with various germs, and the sterilization ability can be maximized by that. As the copper metal has a positive charge, bacteria including pathogenic bacteria having negative charges can catch bacteria on the basis of electric charge characteristics. By putting it in place, it inhibits growth and exerts antibacterial properties.

In addition, the non-woven fabric containing the copper fiber prepared according to the present invention was maintained after the 30 times the reduction rate of the strain, which is a measure of antimicrobial activity, and thus it was found that the washing durability of the copper fiber is excellent, the copper fiber prepared according to the present invention The non-woven fabric containing the organic mercury compounds, Deldrrin, PCP, formaldehyde, tributyl tin compound, trimethyl tin compound, DTTB was not detected. In addition, after the non-woven fabric containing copper fiber prepared according to the present invention was patched on the skin of 20 subjects, the inertia test on the skin irritation was performed by Kawai's method. Since it was judged to be quasi-negative because no irritation occurred, it was confirmed that the nonwoven fabric containing copper fiber of the present invention was harmless to the human body and had no irritation to the skin.

Hereinafter, preferred embodiments of the present invention will be described in detail by the accompanying drawings.

Experimental Example 4: Skin irritation test (Kawai's Method)

The subjects of this study were 20 healthy males and females in their 20s. The duration of the test was from March 20, 1999 to March 31, 1999. The result of the experiment was Prof. Moon Ki-chan, a professor of dermatology at the University of Ulsan. After cutting the verbal fabric into 2 × 2cm size, placing it in a fixed place inside the arm and pressing it with a medical bandage that allows air to be vented above it, the specimen was removed from the skin 48 hours later and the D-STAGE reaction was determined by visual judgment. Investigate. For the absence of abnormalities, skin replica samples of the patched areas were prepared by the Sump method. The prepared specimens were judged by observing the degree of stimulation under a microscope, and the index of the difference obtained by subtracting the control stimulus index from the test stimulus index of 20 subjects was determined. White cotton wool was used as a control, and one out of 20 people was positive (+) by visual judgment (D-Stage), and when the power was negative, the round stage (A-Stage), deep stage (B-Stage) and shallow Shallow Furrows, Vanishing Furrows, Irregular Ridges and Furrows, Cresed Ridges, Lamellar Scale (C-Stage) and D-Stage Was used. In the case of the round stage, after removing the specimen, it returned to normal skin 24 hours later and responded to the mild stimulus. Judgment was made except for the difference. That is, it determined by dividing into four steps as follows.

Negative: (Irritation index of test piece-stimulation index of control group ≤ OB)

Semi-negative voice: (Irritation index of test piece-Stimulus index of control group = 1B ~ 2B)

Semi-positive: (Irritation index of test piece-stimulation index of control group = 3B)

Positive: (Irritation index of the test piece-stimulation index of the control group ≥ 4B)

D-Stage was used to determine the phenomenon of edema, erythema and papules on the skin. The criterion was four levels of negative, quasi-negative, quasi-positive, and positive, and it was determined that even one of the subjects was positive. As a result, as shown in Tables 4 and 5, the antimicrobial verb knitted fabric of the present invention showed the degree of human skin irritation as quasi-negative 2B.
