Description

Urinary incontinence panties using knitted fabric that is simultaneously absorbent and quick-drying {Incontinence panty}

The present invention relates to urinary incontinence panties, and more specifically, to urinary incontinence panties using a knitted fabric that simultaneously exhibits sweat absorption and quick drying properties.

Typically, urinary incontinence is a condition in which urine comes out spontaneously regardless of one's will. Recently, the average life expectancy has been extended, and the prevalence of urinary incontinence is also increasing along with the increase in the elderly population. Most patients leak urine without realizing it when they exert force on their stomach, and some even experience urine leakage when they sneeze or laugh out loud.

In addition, most of these patients have a cold lower abdomen and suffer from frequent cystitis due to poor urinary excretion function. In general, urinary incontinence symptoms occur more often in women than in men. This is because the urethra in women is shorter than that in men, and the pelvic muscles that support the bladder and urethra in women easily become weak due to pregnancy, childbirth, etc. More than 40% of women giving birth in Korea are experiencing inconveniences in their lives related to urinary incontinence, but due to personal shame, public consensus has not been formed, so many improvements have not been made.

On the other hand, urinary incontinence is not good for hygiene, as when moisture persists, odors and bacteria are generated, which can lead to infection with other diseases, which can harm the health of people with urinary incontinence symptoms.

In particular, patients suffering from urinary incontinence, which causes urine to leak regardless of their will, are likely to be reluctant to engage in external activities outside the home due to a great sense of loss and increased anxiety. Possible urinary incontinence panties have been researched and developed, and representative products include washable textile products and disposable diaper products.

However, existing urinary incontinence panties have poor absorption and drying performance, making them uncomfortable to use.

Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

Figure 1 is a perspective view of the urinary incontinence panties 10 according to an embodiment of the present invention, and Figure 2 is a cross-sectional view of the fabric of the urinary incontinence panties 10 according to an embodiment of the present invention. The panties 10 include a urinary incontinence panty body portion 100 and a urinary incontinence absorbent portion 200.

The urinary incontinence panty main body 100 is provided with two leg insertion parts into which the user's legs are inserted so that the user can wear and fix it in the pelvic part of the body, and the pelvic side is preferably made of an elastic material that can be pressed against the pelvic side.

The shape of the urinary incontinence panty main body 100 is shown in Figure 1 as a general triangular panty shape, but it can be implemented in various shapes such as a square shape or a draw shape depending on the user's choice.

Next, the urinary incontinence panties 10 according to an embodiment of the present invention include a urinary incontinence absorbing part 200 on the user's genitals and anus that absorbs secretions including urine secreted from the user.

In one embodiment of the present invention, the urinary incontinence absorbent part 200 is displayed separately, but depending on the user's selection, the entire urinary incontinence panty body part 100 can be formed as an integrated piece with the material of the urinary incontinence absorbent part 200.

Alternatively, depending on the user's choice, the urinary incontinence absorbent portion 200 may be provided in the form of a pad and may be provided in a form that is detachable from the urinary incontinence panty main body 100.

The urinary incontinence absorbent unit 200 includes a water intake layer 210, an absorbent layer 220, and a waterproof layer 230, as shown in FIG. 2 .

Depending on the user's selection, a separate outer surface layer 240 may be formed outside the waterproof layer 230.

First, the water intake layer 210 is a part where secretions including urine secreted from the user enter the urinary incontinence absorption unit 200 and are configured to allow the secretions to be quickly obtained.

And the water intake layer 210 is a part that comes into contact with the user's body and is configured to have a cooling function to provide a refreshing feeling to the user when in contact with the body.

The fabric constituting the water acquisition layer 210 is a functional polyester fiber with a different cross-section and has quick-drying properties.

In the present invention, when secretions including urine etc. are received into the water intake layer 210 using the above-described irregular cross-section polyester long fiber, if there is a difference in the thickness and density of the fabric within a certain pattern, the capillary tube is formed in the area where the difference occurs. The phenomenon manifests itself well. To ensure that properties such as absorbency and drying properties are well expressed, the wavy pattern knitting design is used to transfer to the absorption layer 220 through absorption and diffusion phenomena.

As shown in Figure 3, the wavy patterned fabric using the irregular cross-section polyester long fiber is designed to have high absorbency and absorption rate and has the function of quickly absorbing the secretion, and the secretion absorbed by this knitted structure is absorbed, diffused, and transferred. Since it is quickly discharged to the absorption layer 220 through development, a pleasant feeling can be provided to the user.

Next, the urinary incontinence panties 10 according to an embodiment of the present invention are constructed to provide excellent absorbency and quick-drying properties at the same time by forming a hydrophilic film on the polyester long fibers of different cross-sections.

That is, the polyester long fiber was processed with an absorption desiccant, which consists of 2 to 3% by weight of a hydrophilic polymer, 1 to 10% by weight of a hydrophilic cationic polymer or cellulose polymer or silicone softener or urethane softener, and the remaining amount of water as a solvent. It comes true.

Test Items Comparative Example this invention Absorption time (S) 5.30 2.42 Absorption rate (%/S) 37.96 52.49 Maximum absorption radius (mm) 19 30 Diffusion speed (mm/S) 2.58 7.49

(Table 1) shows the comparative test results between the absorbent layer 220 knitted with the irregular cross-section polyester long fibers processed with the absorbent desiccant and the irregular cross-section polyester absorbent layer 220 not processed with the absorbent desiccant. The absorption layer 220 processed with the absorption desiccant according to one embodiment of the invention shows superior performance compared to the comparative example in terms of absorption time, absorption rate, maximum absorption radius, and diffusion rate.

Next, the secretion obtained through the water intake layer 210 quickly moves to the absorption layer 220 and is absorbed.

The fabric of the absorbent layer 220 is configured to form capillaries between fibers so that the secretion is quickly absorbed. That is, in the present invention, as shown in FIG. 2, polyester long fibers are used as fibers used in the absorbent layer 220, and the cross-sectional shape of the polyester fibers is made to have the shape of a four-lobed crowbar leaf.

In this way, the polyester fiber forms four capillaries and moisture moves freely through them, so it has the function of quickly absorbing the secretion.

Test Items Comparative Example 1 Comparative Example 2 this invention Drying speed (g/25CMㅂ) 11.7 15.6 16.44

(Table 2) compares the drying speed of the urinary incontinence absorbent part 200 including the absorbent layer 230 according to an embodiment of the present invention with Comparative Example 1 (Japanese MRS) and Comparative Example 2 (Japanese 7N). As a result of the test, the urinary incontinence absorbent unit 200 including the absorbent layer 230 according to an embodiment of the present invention showed significantly superior test results in terms of drying speed compared to Comparative Examples 1 and 2.

Next, the waterproof layer 230 is made of polyethyleneterephthalate (PET).

It is a waterproof layer 230 that exhibits moisture permeability and waterproofing properties. This waterproof layer 230 is manufactured by joining the edges of the waterproof layer 230 using sewing thread when combining urinary incontinence panties or inserting them without bonding.

The waterproof layer 230 forms a pore structure by applying a thermal fusion process using heat and pressure to a web formed by accumulating microfibers made of a polymer material.

That is, in the urinary incontinence panties 10 according to an embodiment of the present invention, the waterproof layer 230 is made of a polymer material that exhibits adhesiveness on the surface of the waterproof layer 230 for adhesion to the absorbent layer 220 so as not to affect breathability. It is applied in a pattern and adhered to the absorption layer 220 through heat fusion without separate physical bonding using sewing thread or the like.

The urinary incontinence panties 10 according to the present invention have the effect of providing excellent wearing comfort to the wearer by using a knitted fabric with excellent absorbency and drying properties, as urine is quickly absorbed and dried in the urinary incontinence panties.

Next, the urinary incontinence panties 10 according to the present invention have a protrusion (not shown) on the urinary incontinence absorbent part 200 to improve the leakage of the secretions or the user's wearing comfort.

That is, the protrusion forms a pleated portion with a plurality of internal spaces formed along the circumference of the urinary incontinence absorbent unit 200, and a pulling portion such as a string that can be pulled by the user from the outside is provided in the inner space of the pleated portion so that the user can When the pull portion is pulled, the pleated portion is folded and protrudes into the inside of the urinary incontinence panties (10).

In this way, when the wrinkles protrude inward, the protrusions can prevent the secretions from leaking outward, and can improve the user's wearing comfort by contacting the user's skin at a distance from the inside of the urinary incontinence panties 10. .

Depending on the user's choice, the inner space of the protrusion can be filled with a highly absorbent polymer that absorbs the secretions.

In this way, when the inner space of the protrusion is filled with a super-absorbent polymer, when the user pulls the pull part, the protrusion containing the super-absorbent polymer protrudes inward, and the super-absorbent polymer first comes into contact with the secretion, removing the secretion. By absorbing it, it is possible to prevent the secretion from spreading throughout the inside of the urinary incontinence panties 10.

Although the preferred embodiments of the present invention have been described above, various changes, modifications, and equivalents may be used in the present invention. It is clear that the present invention can be equally applied by appropriately modifying the above embodiment. Accordingly, the above description does not limit the scope of the present invention, which is defined by the limitations of the following claims.
