Description

Reusable high absorbent pad fabric

The present invention relates to a reusable physiological type and incontinence pad fabric, and more particularly, to a superabsorbent pad fabric that can be reused by washing. In addition, such a pad fabric may be used attached to the panties.

Conventional disposable sanitary napkins are basically composed of a cover, cotton, an absorbent material composed of a polymer absorbent material, and a waterproof membrane composed of a polyethylene film, and are used by removing and attaching the sanitary napkin to underwear through a double-sided tape.

The polymer absorbent applied to the sanitary napkin serves to hold menstrual blood from leaking, and it is a substance that is usually in powder form, but changes to gel form when menstrual blood is absorbed.

However, the polymer absorbent mainly used to impart strong absorption power causes itching, dermatitis, odor and various inflammatory diseases by formaldehyde (a substance that causes sick house syndrome), a carcinogen generated during the manufacturing process. This causes difficulties in the life of the user.

The reason why acne, cold, and body aches occur during menstruation is believed to be due to the large influence of this substance, and because the original shape is in the form of a solid powder, the fine powder of this powder penetrates the surface layer and enters the endometrium, causing dryness of the uterus, resulting in dryness of the uterus. As a result, it reduces normal uterine function and can cause dry uterus, endometriosis, and uterine fibroids. This type of female disease spreads inflammation not only to herself but also to sexual contacts, leading to various urinary system diseases including the prostate.

In addition, menstrual blood absorbed by the polymer absorbent is not ventilated by the waterproof membrane made of polyethylene film, so the odor is confined in a narrow space, and bacteria naturally multiply, causing dermatitis or severe itching in and around the vagina. may also induce

In addition, menstrual blood absorbed by the polymer absorbent material is not ventilated by the waterproof membrane made of polyethylene film, so the odor is confined in a narrow space, and bacteria naturally multiply, causing dermatitis and severe dermatitis in and around the vagina. It can also cause itching.

On the other hand, disposable sanitary napkins have not only the problems described above, but also have a problem of greatly damaging the global environment by generating microplastics because chemical fibers that are very difficult to decompose in nature are used.

Recently, in order to solve this problem, there has been introduced a product that can be reused after washing by attaching a pad made of a hygroscopic fabric to a portion in contact with the vulva of the panty. Such a hygroscopic pad is responsible for rapid moisture absorption and moisture storage through the water retention layer, and by preventing the moisture absorbed by the waterproof layer from leaking through the bottom, it has the effect of improving cleanliness by keeping the skin dry.

Although this type of pad has the advantage of being reusable, it still has problems with conventional sanitary napkins such as generation of bad odors and proliferation of bacteria.

As an example of a technique for solving this problem, Korean Patent Laid-Open No. 10-2003-0077509 (a sanitary napkin containing an oriental medicine composition and a method for manufacturing the same) can be exemplified. In the literature, a fine powdered oriental herbal composition is deposited by mixing oriental medicinal ingredients such as mugwort (aeyeop), angelicae, mint, sagebrush and motherwort in a certain ratio, or impregnated with an oriental medicine composition extract extracted in liquid form, dried and gel It is disclosed that by inserting and fixing the menstrual blood absorbent pad to which the oriental medicinal composition is fixed between the outer sheets, it is possible to maintain cleanliness by preventing the propagation of bacteria due to secretions through the pharmacological action of the oriental medicinal composition.

However, such prior literature exhibits the effect of suppressing the generation of odors and the proliferation of bacteria, but still has a problem of greatly damaging the global environment by using disposable sanitary napkins that are difficult to decompose in nature.

Meanwhile, in Korean Utility Model No. 20-0443017, a recyclable sanitary napkin in which the uppermost layer made of pure cotton, the lowermost layer made of moisture-permeable and waterproof fiber material, and 3 to 4 superabsorbent fiber layers in the longitudinal direction are laminated between the top and bottom layers. has been disclosed.

However, these sanitary napkins are reusable and thus play a role in protecting the global environment, but do not exert the effect of suppressing the generation of odors and the proliferation of bacteria.

An object of the present invention is to provide a fabric for menstrual blood and incontinence pad that can be reused by washing to solve the above problems.

Another object of the present invention is to provide a reusable pad fabric capable of suppressing the generation of odors and the proliferation of bacteria.

Another object of the present invention is to provide a reusable pad fabric whose function is maintained even if reused several times.

Another object of the present invention is to provide a reusable pad fabric in which comfort is continuously maintained when worn.

Another object of the present invention is to reduce the manufacturing cost by increasing the productivity when manufacturing the product by making the surface layer (absorbent layer) and the water-retaining layer integrally.

The pad fabric of the present invention consists of a surface layer (absorbent layer), a water-retaining layer and a waterproofing layer, the surface of the surface layer is composed of polypropylene fibers and antibacterial and deodorizing polyester fibers, and the back surface of the surface layer is composed of antibacterial and deodorizing polyester alone.

The water retaining layer is composed of nylon fibers containing nano copper components and polyester fibers that are antibacterial and deodorant.

The waterproof layer is composed of a polyurethane or polyester film.

Hereinafter, the present invention will be described in detail.

The surface of the surface layer (absorbent layer) of the present invention is composed of polypropylene fibers and antibacterial and deodorizing polyester fibers. Examples of antibacterial and deodorizing polyester fibers include Aerosilver (Hyosung Joo), ATB (TK Chemical Co., Ltd.), and Linol fiber (Linol Polytech Co., Ltd.).

Polypropylene fibers are ultra-hydrophobic fibers that quickly move surrounding moisture to other places and serve to keep the surface dry. A suitable ratio of polypropylene fiber to antibacterial and deodorizing polyester fiber is 40-60:60-40. In order to give the user a soft feeling and to quickly send the incoming moisture to the maintenance layer, which will be described later, the ratio of use in this range is appropriate. The back side of the surface layer is composed of an antibacterial and deodorizing polyester fiber alone.

Antibacterial and deodorant fiber refers to a fiber having an antibacterial property of 90% or more and an excellent deodorization rate against the four major odor-causing substances such as ammonia, acetic acid, isocylacetic acid, and nonenal. It refers to a fiber having a deodorization rate of 50% or more with respect to two or more. Among the four major odor-causing substances, isogilacetic acid is mainly responsible for foot odor, and nonenal is a substance that causes body odor or old-age odor.

On the other hand, it is preferable that the antibacterial and deodorizing polyester fibers have excellent absorbency.

In order to configure the surface layer as described above, it should be knitted in a double structure with a circular knitting double-sided machine. Jacquard organization is also included. Through this configuration, the surface of the surface layer quickly sends absorbed moisture to the back surface of the surface layer.

The water retention layer of the present invention serves to store moisture, etc. moved from the surface layer, and is composed of nylon fibers containing nano-copper components and antibacterial and deodorizing polyester fibers. Nylon fiber containing nano copper component serves to further reinforce antibacterial and deodorizing properties. A more preferable form of the water retaining layer is a fabric with a two-layer structure in which nylon fibers containing nano-copper components and antibacterial and deodorizing polyester fibers are as the bottom, and antibacterial and deodorizing polyester fibers are formed thereon as piles. The appropriate height of the pile is 3,0~5.0mm. As an example of the pile forming method, a loop may be formed on the bottom layer with a circular knitting terry machine, and then the loop may be popped and erected through processing to form a pile shape.

The water-retaining layer made in this way becomes a one-piece that has joint points at appropriate intervals by using a high-frequency bonding machine together with the surface layer, so that absorption, delivery, and storage occur quickly.

The water retention layer of this configuration can be stored smoothly even if a large amount of menstrual blood or urine temporarily flows into the space formed by the pile, and is absorbed by the highly absorbent antibacterial and deodorant polyester fiber or nylon fiber over time.

The waterproof layer of the present invention serves to prevent the menstrual blood stored in the water retention layer from leaking to the outside, and a waterproof lamination is performed on the back surface of the water retention layer, and the material used is a polyurethane or polyester film or non-woven fabric. The waterproof layer preferably has appropriate softness and thickness so that it can be attached or sewn to panties or the like. In addition, it is more preferable that the waterproof layer is made of a material that allows air to pass while not allowing moisture to pass therethrough.

The pad fabric of the present invention can be reused by washing, and the generation of odor and the proliferation of bacteria are remarkably suppressed during use, and the surface of the surface layer in contact with the skin always maintains a dry state during use, thereby providing a feeling of comfort, disposable sanitary napkins It has the effect of greatly reducing the pollution of the global environment through the use of

In addition, even if the pad fabric of the present invention is reused by washing, antibacterial and deodorizing properties are retained for a long time.

1 is an exploded perspective view of the super absorbent pad fabric of the present invention.

The term "pad fabric" used in the present invention refers to hygiene for preventing fluid leakage, such as sanitary napkin pad, diaper pad, incontinence pad, adult panty diaper pad, pet excrement pad, bed pad, nursing pad, etc. It means a fabric that can be used as an article. Also, the term “antibacterial” means having the ability to control at least some kinds of microorganisms, or to inhibit proliferation or reproduction.
