Description

Disposable absorbent products

The present invention relates to disposable absorbent articles. More specifically, it relates to a disposable absorbent product consisting of a liquid permeable top sheet, a fluff pulp, a liquid impermeable back sheet and bioceramics.

The bio-ceramic is a non-metal inorganic material which is synthesized through a high temperature heat treatment process by mixing fine powders of oxide ceramics such as silica, alumina, sodium oxide, potassium oxide, calcium oxide, magnesium oxide and iron oxide, and also known as so-called far-infrared radiation ceramics. It is a substance.

In the present invention, the disposable absorbent product refers to a product absorbing urine secretion, menstrual secretions or vaginal secretions as a product absorbing various physiological fluids, and more specifically, disposable diapers used by infants or adults. ), A sanitary napkin or a pantyliner.

Conventional disposable absorbent products consisting of a liquid permeable topsheet, downy pulp and a liquid impermeable backsheet, the urine component Urea decomposes by Candida Albicans to produce ammonia when worn continuously after pissing, Ammonia produced as a urea breakdown product causes skin irritation, redness and dermatitis, as well as causing unpleasant odor from urine, menstrual or vaginal secretions. There was a problem.

Efforts have been made to reduce or prevent diaper rashes in the past, but no fully satisfactory solution has been obtained.

Korean Patent Laid-Open Publication Nos. 86-8743 and 86-8744 have discussed the reduction of diaper rash by using inorganic acids or by containing acid functional residues to keep the pH in a constant range. Reduction of discomfort from urine, menstrual and vaginal secretions was not satisfactory.

Another method of preventing diaper rash which has been generally attempted in the past is to treat a disinfectant in the diaper, but in this case quite a lot of disinfectants are used to kill bacteria which cause decomposition of urine urea, namely Candida. In addition, the disinfectant is not necessarily an excellent diaper treatment because almost all of them have irritation problems on the skin and do not prevent unpleasant odors caused by secretions.

Therefore, in order to achieve the purpose of the disposable absorbent product with excellent skin safety and a more hygienic product, the disposable absorbent product having both functions of excellent ammonia suppression effect and excellent deodorizing effect to prevent unpleasant odor are It is expected.

The present inventors added bio ceramics to a conventional disposable absorbent product consisting of a liquid permeable top sheet, a fluffy pulp, and a liquid impermeable back sheet to prevent skin irritation and dermatitis by inhibiting the production of ammonia, a degradation product of urine. The present invention has been completed by discovering that the odor generated from urine discharge, menstrual discharge or vaginal discharge can be suppressed.

Accordingly, it is an object of the present invention to provide a safe and more hygienic disposable hop water products for the skin by excellent ammonia generation inhibitory effect, prevent skin irritation and dermatitis, and suppress the discomfort caused by secretions.

The disposable absorbent product of the present invention has such excellent properties as Candida, which is a decomposition bacterium of urea as a urine component by adding bio ceramics to a conventional disposable absorbent product composed of a liquid permeable top sheet, a fluffy pulp and a liquid impermeable back sheet. By inhibiting the activity of the bacteria, not only suppresses ammonia production, but also by adhering the produced ammonia into the structure of the bio ceramics, it inhibits the activity of ammonia, which causes skin irritation and dermatitis, and prevents the occurrence of skin irritation and dermatitis. In addition, it is thought to suppress the unpleasant odor by adsorbing the unpleasant odor generated from urine secretion, menstrual secretion or vaginal secretion into the structure of the bio ceramics.

The bioceramic used in the present invention is composed of oxides produced by silicon, aluminum, sodium, potassium, calcium, magnesium, iron and zirconium, and is composed of two or more kinds of oxides selected from the above components. It is a fine powder. (See Table 1)

In the present invention, the liquid permeable top sheet is known for use in a conventional disposable absorbent article, and the liquid permeable top sheet which is most commonly used is nonwoven.

Fluffy pulp is made of fluff by processing wood pulp and is a known hydrophilic absorbent that absorbs secretions and is used in conventional disposable absorbent products.

In addition, the liquid impermeable back sheet is also known to be used in ordinary disposable absorbent products, and generally used non-breathable waterproof film, breathable waterproof film, and biodegradable waterproof film, and the non-woven fabric for such liquid impermeable back sheet Laminated (Laminate) can also be used.

The present invention uses a known liquid permeable top sheet, a fluffy pulp and a liquid impermeable back sheet which are used in a conventional disposable absorbent article as a main component, and the following are known as auxiliary components in addition to the main component.

(1) tissue

(2) Adhesive tape or fixing button

(3) Front Tape

(4) elastic for thigh or waist

(5) Barrier Cuff, Leg standing Cuff

(6) Adhesive ingredients (Hot melt, Glue, etc.)

(7) Fixing systems for underwear such as panties

It is characterized by containing the above-mentioned bioceramic in a conventional disposable absorbent article which optionally uses such.

There are a number of methods for incorporating bioceramic, which is a known material used in the present invention, into a conventional disposable hop water product, and some of such methods are as follows.

(1) Method to be included in the preparation 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 manufacturing Barrier Cuff

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

(5) Incorporation in the manufacture of disposable absorbent products

The method of (1) to (4) above refers to adding bioceramics in the preparation of the lacquer component. In other words, the liquid-permeable top sheet, fluffy pulp, coagulant band, superabsorbent resin or tissue already containing bio ceramics. Disposable hop water product using is also included in the present invention.

Hereinafter, the present invention will be described in detail by the following examples.

Example 1-10 and Comparative Example 1

A conventional disposable diaper composition prepared according to a conventional disposable diaper manufacturing method by forming a liquid permeable top sheet, fluffy pulp, tissue, and a liquid impervious back sheet was referred to as Comparative Example 1, and the bio-disposable diaper composition according to Comparative Example 1 The ceramics are contained in the fluffy pulp at 0.001%, 0.005%, 0.01%, 0.05%, 0.1%, 0.5%, 1%, 5%, 10% and 15%, respectively, by weight to the total weight of the disposable diaper.
