Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lining structure for providing a dry condition,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lining structure for rapidly absorbing a large amount of sweat or secretion to maintain a dry state on the skin surface, and a cloth diaper or cloth diaper cover, sanitary napkin, incontinence pant,

Many products that absorb water components such as sweat (or urine, hereinafter referred to as water) generated in the human body have been released.

On the other hand, there are also known products which employ hydrophobic fibers to provide a dry condition on the skin-contacting surface at portions that come into contact with the skin.

For example, as illustrated in Patent Application No. 10-1985-0002520, a hydrophilic fiber is formed as a bristle on a contact portion, and the absorbent layer is made into a structure like a fabric composed of microporous layer hollow fibers to provide a dry state on the surface do.

As described above, when the absorbent layer is made of a functional fiber and a large amount of water is discharged from the skin surface even if the speed of absorbing water is fast and the drying speed is fast, and when the contact portion is made of only hydrophobic fibers, The water does not reach the absorbent layer, so that the absorbent layer does not play an essential role.

Cloth diapers, incontinence panties, lining for sanitary napkins, or lining for sportswear which are required to absorb a large amount of water are not suitable for application as hydrophobic fibers. Due to the knitted density of the hydrophobic fibers or the surface tension of the water, water is not passed through the knitted fabric made of hydrophobic fibers. The term "knitting " as used in the present invention refers to weaving, knitting and all fabric manufacturing processes.

On the other hand, in order to solve this problem, a material formed by knitting with a blend fiber of hydrophobic fiber and polyester fiber, or by knitting polyester fiber with hydrophobic fiber is also used. However, in the case of the material thus formed, moisture is contained in the material because of the water-absorbing property of the water-absorbent fiber such as blended or knitted polyester, and it is difficult to keep the surface in a dried state.

The present invention has been made to solve such a problem.

The present invention relates to a cosmetic composition which can rapidly permeate the skin even when a large amount of water in contact with the skin is generated, maintains a dry state on the skin contact surface, provides excellent wearing feeling, will be.

The present invention also provides incontinence panties, cloth diapers, sanitary napkins, underwear, sports clothes, and the like manufactured using such a lining structure.

An object of the present invention is to provide an absorbent article comprising a contact part made of hydrophobic fibers and an outer part made of absorbent fibers absorbing water passing through the contact part and contacting with the contact part and passing through the contact part and the outer part, And an absorption channel which is in contact with the outer side to be exposed only to a specific surface of the contact portion to absorb water and to move the water through the contact portion to the outer side portion so as to maintain the dry state of the contact portion in contact with the skin. Lt; / RTI >

The absorbing channel may be formed of an absorbent sewing thread or a seam, which is disposed at a position corresponding to a skin surface or a human body where a large amount of water such as sweat or secretion is discharged, and at a low position in the gravity direction when applied.

Wherein the hydrophobic fiber is a polypropylene fiber and the absorbent fiber and the sewing thread are made of at least one of polyester fiber, artificial silk, rayon or polyester fiber, anthracite, polyurethane fiber, nylon fiber and acrylic fiber Wherein the hydrophobic fiber is a kapok fiber, and the absorbent fiber and the sewing thread may be made of at least one of cotton, hemp, hemp, and bamboo fiber.

It is preferable that the sewing thread is sewn to be arranged at a corresponding portion where water is generated or is disposed at a portion positioned at a low height in the direction of gravity when worn.

The lining structure may be employed in cloth diapers, urinary incontinence pants, sanitary napkins, clothes, mats, and the like.

The object of the present invention is attained by providing a lining characterized in that the contact portion in contact with the skin is made of a Kwon fiber and the corresponding outer side is made of at least one of cotton, hemp, hemp, and bamboo fiber. Optionally, an absorption channel can be provided.

As used herein, the term "knitting " refers to weaving, knitting.

The lining structure 1 of the present invention is characterized in that the skin contacting portion 1a is made of only hydrophobic fibers and is provided so that the absorbing channel 100 is exposed only in a part of the contacting portion 1a so that the outer side portion 1b made of the absorbent fibers located on the opposite side, So that the water can be quickly moved.

According to one embodiment of the present invention, the lining structure 1 of the present invention is constituted of a contact portion 1a contacting the skin surface and an outer portion 1b of the independent structure, as illustrated in Figs. 1 and 2, The contact portion 1a and the outer side portion 1b may be penetrated by the absorption channel 100 and connected to each other.

As shown in Figs. 1 and 2, it is preferable that the contact portion 1a of the lining structure 1 is formed by knitting entirely of hydrophobic fibers as a portion contacting the skin surface. As the hydrophobic fibers, synthetic fibers may be polyolefin-based polyethylene fibers or polypropylene fibers, preferably polypropylene fibers.

However, the present invention is not limited to the above-mentioned one, and a knitted or woven fabric knitted with polyester fibers mixed with the polyolefin, particularly polypropylene fiber and absorbent material, may be used. However, when the polyester fibers are knitted with the blended blended fibers or the polyester fibers are knitted, the water absorption properties of the absorbent polyester fibers may remain in the knitted fabric, which is undesirable.

As hydrophobic fibers, natural fibers are preferably kapok fibers. However, this embodiment of the present invention does not limit the selection of the material used as the contact portion of the lining of the present invention.

The outer portion 1b is an independent fabric which is separate from the contact portion 1a, and a fiber having excellent absorbency is preferable. It is also possible to use fibers made of sweat-absorbent, quick-drying fibers or superabsorbent fibers of polyester, and fibers with other functions such as anti-bacterial function (ATB). The superabsorbent fiber is a fiber formed by forming a cross-section of a synthetic fiber to have a special cross-sectional structure or, if necessary, coating the cross-sectional structure with a functional material. The outer portion 1b can be processed to have a quick-drying property that is highly water-absorbing and water-repellent at the same time, so that the drying speed of the outer portion 1b can be increased. The superabsorbent fibers are predominantly polyester fibers or artificial yarns, but may also be blended fibers of other fibers. Polyester fiber, polyacrylate fiber, polyurethane fiber, nylon fiber, and acrylic fiber. Further, the superabsorbent fibers may be knitted or knitted in a blended manner with a polyurethane-based material such as polypropylene fibers and used as a material of the outer side portion 1b. Optionally, polypropylene fibers may be blended in one side of the outer side portion 1b disposed on the side facing the contact portion 1a and knitted or knitted.

Natural fibers include cotton, hemp, hemp, and bamboo fibers, and such fibers are not limited to the present invention. Alternatively, the outer portion 1b may be knitted or knitted in blended with natural hydrophobic fibers, such as, for example, kapok fibers.

Preferably, the contacting portion 1a and the outer portion 1b are combined with synthetic fibers, and the natural fibers are preferably combined with natural fibers. For example, the contact portion 1a is made of synthetic fibers, and the outer portion 1b is made of natural fibers. The natural fibers are preferably disinfected by using a neutral detergent or other disinfectant. For example, When the lining structure is cooked at a high temperature in the case of the fiber, the contact portion 1a, which is a synthetic fiber, is weak against heat, which causes an undesirable situation such as a deformed structure of the lining structure. However, even if a combination of natural fibers and synthetic fibers is used, the deformation of the synthetic fibers does not occur during the high temperature sterilization washing, or the natural fibers combined with synthetic fibers such as cotton can be combined if sterilization is safely performed even by washing with a neutral detergent.

As the contact portion 1a of the lining structure is entirely made of hydrophobic fibers, not only does it provide the user with a dry condition, but also the hydrophobic fibers are generally smooth on the surface, so that the water of the excreta or secretion is not buried in the lining structure. With this configuration, it is possible to facilitate the washing of the product adopted as the lining structure.

However, when the contact portion 1a of the lining structure is formed of hydrophobic fibers, if a large amount of water is generated, water can not be quickly transmitted to the outer portion 1b through the contact portion 1a. In order to solve such a problem, even if the size of the mesh of the knitted fabric constituting the contact portion 1a is formed to be large, permeation of water is not smooth. The mesh referred to in the present invention refers to pitchers (not shown) formed between knitted or woven yarns. The term "mesh" is for illustrative purposes only and is not intended to limit the scope of the invention.

On the other hand, in order to smooth the permeation of water from the contact portion 1a to the outer portion 1b, processing with the softening agent for absorbing softening agent is added during knitting of the contact portion 1a to improve the permeability of the contact portion 1a to water However, it has been found that an additional treatment such as an absorption softening agent can not improve the permeability of the contact portion 1a to a large amount of water.

In order to overcome this problem, the inventor of the present invention has found that, in order to smoothly flow a large amount of water applied to the contact portion 1a to the outer portion 1b, ) And the outer portion 1b.

In another embodiment of the present invention, the absorber 2 may be separately disposed at a lower portion of the lining structure 1 including the contact portion 1a and the outer portion 1b. 2, the absorption channel 100 penetrating through the outer side portion 1b of the contact portion 1a has an absorption channel 100 as a sewing thread to smoothly transfer the water of the absorption portion 2 (Not shown) of the laminated absorber 2 or a whole layer (not shown) of the laminated absorber 2.

1 to 3, the sewing thread is brought into contact with the contact portion 1a and the outer side portion 1b by a sewing machine (not shown) Respectively.

Preferably, the sewing thread is made of a functional fiber of a polyester material having a high water absorbency and a thread made of a material such as cotton or hemp is preferably used in the case of a lining structure made of a kapok fiber and a natural absorbent fiber. It can be applied in the same manner as the fiber constituting the outer side portion 1b as mentioned above. However, a yarn made of a blend fiber can be used, and the selection of such a material is not limited to the present invention.

The length of the sewing thread between the contact portion 1a and the outer side portion 1b is short so that the contact portion 1a and the outer side portion 1b are in close contact with each other only at the sewing thread portion. The absorption channel 100 made of the sewing thread is exposed on the contact portion 1a.

As the length of the sewing thread between the abutting portion 1a and the outer portion 1b is short, the absorbing and delivering speed to the outer portion 1b is fast. As a result, the water, which has not been permeated by the surface tension on the hydrophobic fibers, The surface tension is destroyed and is quickly absorbed into the outer side portion 1b. Only through the absorption channel 100 composed of the sewing thread exposed on the contact portion 1a, the water is moved to the outer portion 1b, absorbed, and diffused in the outer portion 1b.

As shown in FIG. 6, the absorbent channel 100 may be formed of a material such as sweat or secretion such as a skin surface on which a large amount of water is discharged, such as an armpit, a groin, It is preferable to arrange them so as to be arranged at positions corresponding to the organs such as genital organs (100a to 100e). 6, when the product adopting the lining structure 1 is worn, the absorption channel 100e is arranged at a lower position in the gravity direction so that the water flows downward in the gravity direction, So that water is absorbed through the absorption channel 100 disposed in the outer side portion 1b to be moved to the outer side portion 1b.

According to this configuration, a large amount of water generated on the skin surface or other human body is absorbed by the absorption channel 100 which is in contact with the contact portion 1a and exposed on the contact portion 1a, The water is rapidly moved to the outer portion 1b which is in contact with the absorption channel 100 and water is diffused in the outer portion 1b. Since the contact portion 1a is a hydrophobic material, no water remains and the water is prevented from flowing back to the contact portion 1a from the outer portion 1b, Thereby providing the user with a dry condition.

The higher the knitting density of the contact portion 1a, the more the number of the absorption channels 100, the contact area, or the application amount should be increased to facilitate absorption. However, in order to provide a dry state, i.e., a dry feeling, which is one of the intrinsic characteristics of the hydrophobic fibers, it is preferable that the absorption channels 100 are arranged to be arranged in only a limited part as possible.

In some products, hydrophobic fibers and polyester fibers are knitted to form a knitted fabric to improve the water permeability of the hydrophobic fibers, but polyester fibers are distributed throughout the knitted fabric to completely realize a dry state characteristic of the hydrophobic fibers It is difficult. However, the absorbent channel 100 of the present invention as described above can be partially exposed to the contact portion 1a by the sewing thread and can expose a portion of the absorbent channel 100 that absorbs only a specific portion in contact with the skin, It is possible to effectively provide the property of maintaining the dry state, which is the original characteristic of the hydrophobic fiber constituting the contact portion 1a.

In addition, compared to the cost of producing a knitted fabric formed by knitting hydrophobic fibers and absorbent fibers, the structure of this absorbent channel 100 of the present invention can be manufactured by only a simple sewing process, Therefore, the effect is also great.

Although the absorption channel 100 may be a sewing thread, another structure may be applied to connect the contact portion 1a and the outer portion 1b to transmit water. For example, the contact portion 1a and the outer portion 1b may be joined together in the same manner as the bonding to form a structure capable of transferring water. It is within the scope of the present invention that the bonded portion is structured or configured to absorb and transmit water and the contact portion 1a and the outer portion 1b are connected to each other through a functional and functional surface to transmit water .

The absorbent channel 100 may be excluded and applied in accordance with the mesh or other specifications of the contact portion 1a as well as the contact portion 1a made of the cowwoven fiber and the outer portion 1b of the lining structure 1 made of the absorbent material of natural fibers. On the other hand, the kwon fiber constitutes the contact portion 1a and can be constituted of a single fabric, which is knitted or knitted so as to form the outer portion 1b with natural fibers having absorbency or blend fibers thereof. For example, the kawarp fiber is made of terry or loop, and the natural fiber made of absorbent cotton, hemp, cotton, bamboo fiber and the like can be knitted into the ground and used. It will be appreciated by those skilled in the art that other knitting methods of this type may be employed and employed.

Since the contact portion 1a and the outer side portion 1b of the lining structure 1 of the present invention are made of different materials, it is preferable that the final products formed by combining these materials take into account the mutual shrinkage ratio. There is a possibility that the outer shape of the lining structure is deformed due to the difference in shrinkage or expansion ratio of different materials constituting the lining structure 1 after heat is applied or after washing. In order to solve this problem, it may be desirable to form the knitting weight / yard of the contact portion 1a and the outer portion 1b of the lining structure 1 differently. For example, it is preferable to make the weight / yard of the contact portion 1a smaller than the weight / yard of the outer portion 1b. As a result, the contact portion 1a made of the hydrophobic fiber is formed at a low weight / yard to form a large mesh, so that the water permeation can be made somewhat smooth, and the mesh of the contact portion 1a is formed largely, The mesh of the contact portion 1a compensates for deformation of the outer side portion 1b due to the margin of the mesh of the contact portion 1a so that it is easy to maintain the shape of the lining structure 1 as it is. This weight / yard difference is not limited by the above description of the present invention.

According to another embodiment of the present invention, the lining structure 1 as described above can be applied to underwear, sports clothes, outdoor clothes, medical rugs or pads which require much water absorption. The underwear is especially incontinence panties, and is also applicable to cloth diapers and sanitary napkins. The sports garment or the outdoor garment can be applied to both under the top of the direct contact with the skin.

As shown in Fig. 3, in the upper and lower garments, only the topsheet 200 is shown for illustrative purposes.

3, when the lining is applied to a garment, the portion 100a corresponding to the side where the wearer sweat a lot, the portion 100b between the chest and abdomen, the portion corresponding to the chest bone 100c, It is obvious that the number and position of the absorption channels 100 can be added in consideration of functions and design in processing. The outward surface of the illustrated embodiment of Fig. 3 is the lateral portion 1b of the lining structure 1 of an embodiment of the present invention.

When the lining structure 1 of the present invention is provided on the garment, the stitching chamber constituting the absorption channel 100 is formed in a closed space such as a circle, a polygon, or the like in the contact portion 1a and the outer portion 1b It is preferable to perform sewing so as not to form a shape capable of forming a closed space. Such a closed space between the contact portion 1a and the outer side portion 1b serves to interfere with air communication by forming an air layer, which is not preferable.

Figs. 4A to 4C show another embodiment of the present invention employing the lining structure 1, which is a simple example of the lining structure in the cloth diaper incontinence pant or the sanitary napkin, the arrangement structure of the absorbent portion and the cloth.

As illustrated in FIG. 4A, the lining structure 1 is combined with the outer cloth 3 and the space 5 to form an integral body, a book shape, or a separate structure. As the outer surface 3, a general polymer fiber or a material obtained by laminating a waterproof layer on a natural fiber may be used. However, the outer surface 3 of the synthetic fibers is made of only polypropylene fibers, and optionally the terry or bristles of the polypropylene fibers are formed on one surface to serve as the laminating layer, Can not be counted out.

4a to 4c, an absorbent portion 2 is disposed between the lining structure 1 and the outer cloth 3, and the absorbent portion 2 is disposed between the lining structure 1 and the outer cloth 3, Or secretion of water. The absorbing portion 2 may be made of natural fibers, synthetic fibers, or blend fibers thereof, or natural fibers and synthetic fibers may be each woven. The lining structure 1, the absorbent portion 2 and the outer cloth 3 are independently formed and inserted between the lining structure 1 and the outer cloth 3 through the space 5 so that the absorbent portion 2 is inserted . Alternatively, the absorbing portion 3 may be integrally formed with the lining structure 1 and the outer cloth 3. [

The absorbent portion 2 disposed between the outer cloths 3 of the lining structure 1 may be made of the same material as the outer side portion 1b or may be made of different materials. In order to increase the amount of absorption, a knitted fabric of an absorbent material may be laminated and used as a bar.

As mentioned above, the absorbing channel 100, which is a sewing thread, may be configured to penetrate through some layers or layers (not shown) of the absorbing portion 2 stacked. However, if the outer cloth 3 is passed through the absorption channel 100, which is a sewing thread, water is leaked through the sewing thread, so that the waterproof function of the outer cloth 3 can not function substantially. Therefore, It is not desirable for the channel 100 to pass through.

Fig. 5 is a view illustrating the incontinence panty which employs the lining structure 1 of the embodiment of the present invention. The absorbent channels 100,100d-100f of the present invention) are sewn together with the lining structure 1 provided and the sewing portions 14,14'joined by the stretch span member 12 to form the incontinence panty .

As described above, it is preferable that the absorbent channel 100, which is a sewing room of the cloth diaper or urinary incontinence pant 300, is disposed at the corresponding position 100d of the human body, which is a human body in which water is generated when worn. Also, it is preferable that the absorption channel 100 is disposed so as to be positioned at the lower portion 100e in the direction of gravity when worn, as shown in Fig. Then, the sewing thread is arranged in the corresponding portion 100f of the crotch side so as to prevent the water from being taken out to the outside.

As illustrated in Fig. 4 (c), between the absorbent portion 2 and the outer cloth 3 made of synthetic fibers, there is used a cloth such as an artificial or visible fiber capable of preventing the static electricity due to the functional force, A second absorbing portion 20 made of lyocell, or tencel fiber may be disposed.

The second absorbent portion 20 can prevent static electricity when the lining structure 1 and the absorbent portion 2 are combined with synthetic fibers. In the case where the absorbent portion 2 is made of natural fibers such as cotton, the second absorbent portion 20 is not required.

As the second absorbing portion 20 is disposed, it is possible to prevent the backflow of water from the absorbing portion 2 to the lining structure 1 by providing a mass transfer gradient, thereby increasing the absorbing power.

According to this configuration, since the cloth diaper, the incontinence pant 300 or the sanitary napkin of the present invention is implemented, since no water remains in the lining structure 1, the sanitary napkin, the urinary incontinence pant, or the wearer of the sanitary napkin is provided with a dry state, .

In another embodiment of the present invention, the moving deformable member 6 is connected to the cloth diaper 300 as illustrated in Figs. 7A to 7B by the upper engaging portion 7 and the lower engaging portion 7 '. The upper and lower engaging portions 7 and 7 'are made of elastic members and can be deformed in the longitudinal direction. A binding member 4 is attached to one side of the outer cloth 3 and another binding member 4 is attached to the moving and deformable member 6. [ As illustrated in FIGS. 7A and 7B, the binding distances of the binding members 4 and 4 'are adjusted by the lower binding portions 7' to serve to tighten the legs or thighs 8, (7) to adjust the binding distance of the binding members (4, 4 ') to tighten the abdomen portion (9). With this structure, especially in the case of infants, since the abdominal breathing is carried out, a form in which the abdomen is not directly pressed as in the present invention is provided, thereby providing comfort.

The binding members 4 and 4 'can be constituted by snap buttons and the kind thereof is not limited. It will be appreciated by those skilled in the art that other members such as velcro, such as buttons, may be employed.

By adopting such a fastening structure, it is possible to provide a cloth diaper which can be applied to infants 1 to 3 years old in one type.
