Description
Technical Field
The present invention relates to the field of absorbent articles, such as diapers, incontinence guards or sanitary napkins and the like.
Background
As the access threshold of the disposable sanitary products industry is not high, more and more new enterprises are continuously emerging, and more kinds of disposable sanitary products can be contacted by people. Paper diapers are widely used for the elderly, patients with special diseases and infants. Especially for infants, paper diapers have become one of the indispensable daily necessities in the growth process of infants.
Paper diapers are disposable absorbent articles which are rapidly growing in recent years, and the quality of products of various manufacturers is uneven. Most manufacturers are continuously pursuing the thin, breathable and dry products, but in order to meet the requirements of quick sales, the performance of the products often stays on the level of good display effect, and how to realize small performance in the real use condition of babies is not carefully studied. For paper diapers, a plurality of different absorption states exist, and when a baby crawls and walks, the paper diaper absorbs under the condition of no pressure; when the baby is in a state of lying, sitting and holding by parents, the paper diaper absorbs under the bearing pressure. At present, more attention is paid to the absorption performance of paper diapers under the condition of no pressure, and the attention to the absorption performance under the pressure is far from sufficient. In addition, in order to obtain soft hand feeling, the designer mainly pays attention to the softness of the material when selecting the material, but neglects the balance between softness and fuzzing, and does not pay attention to whether the material meets the softness requirement and can ensure smoothness (low friction coefficient). But these ignored elements are often factors that have a significant impact on the baby. In summary, the following drawbacks are common to conventional absorbent articles such as diapers:
1) Although most manufacturers make paper diapers as thin as possible, the implementation means are different. Some paper diapers are simply thinned in the production process, and the paper diapers are packed as tightly as possible, so that the paper diapers are prevented from being fluffy and the overall thickness of the paper diapers is prevented from being increased. However, this approach greatly reduces the softness of the diaper product itself, and increases the hardness of the product. In addition, some factories use a composite core body in the form of a bulky nonwoven fabric, and polymers are fixed between fibers of the bulky nonwoven fabric by a hot melt adhesive, so that the air permeability and water absorption of the composite core body with such a structure are remarkably reduced and the touch feeling of a user is hardened due to the use of a large amount of hot melt adhesive. For the composite core with a multilayer structure, the performance is slightly improved, and different layers in the composite core adopt different polymer materials so as to improve the overall performance of the composite core. However, this structure also requires a large amount of glue for fixing, and the above-mentioned problems are also present.
2) In order to obtain better absorption performance of the diaper in the experimental display effect or in the non-pressure condition, designers often realize the effect by increasing the amount of the polymer absorption resin. However, simply increasing the amount of the polymer absorbent resin leads to deterioration of the repeated absorption performance and deterioration of the absorption performance of the diaper under the pressurized state, and meanwhile, the product can generate obvious granular feel, and the use feeling is affected. If too much polymer absorbent resin is added to the ultra-thin core, the problem that the polymer resin overflows out of the product is also likely to occur.
3) The designer considers the soft touch of the surface of the absorbent article such as a diaper singly, and neglects its effect on the dryness of the product. And the drier fabric is used, so that the hand feeling of the non-woven fabric is often deteriorated. When a baby uses the diaper absorbent article, whether the surface is not dry enough or the surface touch is not soft enough, or after the diaper absorbs urine, the buttocks become flushed due to the insufficient dryness; or the surface is not soft and slippery enough, so that the friction between the paper diaper and the skin is increased, and the skin is worn and reddish.
4) The fine denier fiber is easy to bring water on the surface, so that the surface is not dry enough, and although the fine denier fiber can bring excellent slipping effect, the fine denier fiber is often not used for the surface layer, and the skin-friendly property of the surface layer of the conventional paper diaper product is still to be further improved.
Therefore, the performance and the like of the conventional absorbent articles such as diapers are required to be further improved.

Detailed Description
The following detailed description of the preferred embodiments of the invention, taken in conjunction with the accompanying drawings, is given by way of illustration and not limitation, and any other similar situations are intended to fall within the scope of the invention.
In the invention, the term skin-friendly fiber is a fiber which is harmless to skin, has the characteristics of softness and smoothness, and has good moisture absorption and moisture conduction effects and good skin-friendly property. The term "proximal" refers to the side that is closest to the wearer's skin and "distal" refers to the side that is furthest from the wearer's skin. In the following description, directional terms such as "upper", "lower", "left", "right", etc. are used only for illustration in conjunction with the drawings, and the components of the present invention may be placed in a variety of different orientations, and the directional terms are used for purposes of illustration and not limitation. The "longitudinal direction" means the longitudinal direction of the diaper, the "transverse direction" means the width direction of the diaper, and the "longitudinal direction" thereof is in a perpendicular relationship.
Hydrophilicity is a property that indicates the ability of a material to absorb water. The hydrophilicity can be characterized by a general contact angle in the field, and the smaller the contact angle is, the higher the hydrophilicity is, and the stronger the absorption capacity of the material is; the greater the contact angle, the lower the hydrophilicity and the weaker the absorption capacity of the material.
For convenience of explanation, the material and structure of the absorbent article will be schematically described below using only a diaper as an example, and it is to be understood that other types of absorbent articles such as diapers, incontinence guards, sanitary napkins, and the like may be made of the same material and structure as the diaper, except for a structure for ensuring that the absorbent article can be worn slightly different from the structure of the diaper.
1-2, Wherein FIG. 1 is a schematic perspective view of an unfolded paper diaper according to a preferred embodiment of the present invention; fig. 2 is a sectional view of the diaper after being folded along the line A-A of fig. 1, wherein the protector 3 shown in fig. 2 is to be in an upright state in a use state. The diaper of the present invention has a main body 100 capable of contacting the skin of a wearer. The main body 100 comprises, in order from the proximal side facing the wearer's skin towards the distal side facing away from the wearer's skin, a water permeable facing layer 1, an absorbent body 5, a water repellent backing layer 2. The water permeable surface layer 1 is a portion in direct contact with the skin. Wherein, the water permeable surface layer 1 is sequentially provided with an upper water permeable surface layer 12 and a lower water permeable surface layer 13 from top to bottom, and is a double-layer net-laying type hot air non-woven fabric. The fibers of the lower water permeable facing layer 12 extend generally along the length of the absorbent article and the lower water permeable facing layer 13 has a greater hydrophilicity than the upper water permeable facing layer 12. The water-repellent backing layer 2 is located on the distal side of the absorber 5 and is made of a breathable water-impermeable material. The water repellent backsheet 2 can effectively prevent the liquid from overflowing from the thickness direction of the diaper through the water-blocking layer.
After the fiber direction of the lower water permeable surface layer 13 having hydrophilicity superior to that of the upper water permeable surface layer 12 is set as above, the surface of the water permeable surface layer 1 is in a longitudinal stripe shape. The construction mode of the water permeable surface layer 1 can ensure that the diffusion speed of liquid foreign matters such as urine and the like in the thickness direction of the water permeable surface layer 12 is far greater than the diffusion speed of liquid in the longitudinal and transverse directions of the water permeable surface layer 12; and after the liquid rapidly passes through the upper water permeable surface layer 12 and enters the lower water permeable surface layer 13, the liquid can rapidly spread along the longitudinal direction of the lower water permeable surface layer 13. Therefore, the amount of liquid foreign matters existing on the diaper and the permeable surface layer 1 contacting the skin of the wearer is small, so that the wearer can keep dry feeling in the use process. Under the condition of being used as the paper diaper of babies, the paper diaper can effectively avoid the condition of red buttocks.
The water permeable surface layer 1 may be made of skin-friendly fibers, non-skin-friendly fibers, and the like. Wherein the non-skin-friendly fine Denier fiber is a fiber with fineness of 1.0D-1.8D (D: denier, denier), the skin-friendly fiber accounts for 1% -50% of the weight of the water permeable surface layer 1, and the non-skin-friendly fine Denier fiber accounts for 5% -99% of the weight of the water permeable surface layer 1. The water permeable surface layer 1 made of the above material composition has low hydrophilicity, and urine and the like do not stay in the water permeable surface layer 1 in a large amount.
The absorber 5 is a composite core for absorbing and locking liquid, and its thickness is preferably set to be not more than 3mm. The absorber is prepared from fluff pulp, high-molecular water-absorbing resin particles and ES fibers, and does not contain hot melt adhesive. Referring to fig. 5-6, the absorbent body 5 comprises, in order from inside to outside, a water-blocking layer, a conductive layer 52, and a coating layer 53, wherein the coating layer 53 is in contact with the lower water-permeable surface layer 13 and coats the conductive layer 52 and the water-blocking layer. The coating layer 53 preferably has a hydrophilicity that is superior to that of the lower water permeable surface layer 13, i.e., the contact angle of the coating layer 53 is smaller than that of the lower water permeable surface layer 1. Referring to fig. 6, the absorber 5 is distally provided with a longitudinally extending opening 54, whereby the absorber 5 is formed as a semi-closed body. The provision of the openings 54 allows the distal side (lower portion) of the absorber 5 to have less back pressure, and the liquid can be easily diffused to the absorber 5; after the liquid is diffused into the openings 54, since the water-repellent backing layer 2 on the far side is a water-impermeable material layer, even if the liquid sequentially passes through the absorber 5 from top to bottom in a multi-point discrete manner, the liquid can be blocked at the positions of the openings 54 and absorbed by the conductive layers 52, the water-locking layers and the coating layers 53 on the left side and the right side of the openings 54, so that the liquid can be further ensured to be more uniformly diffused to all positions in the whole longitudinal direction of the composite core body, the situation that local liquid is concentrated and the liquid moisture is less at other positions is avoided, and the absorption capacity of the paper diaper is further obviously improved.
Preferably, the width D of the opening 54 of the cover 53 may be set to 5mm to 30mm. In addition, referring to fig. 2,6 in combination with fig. 7, a sealing layer 55 for closing the opening 54 may be provided at the opening 54 of the cover 53. The opening 54 is sealed by the sealing layer 55, so that the width of the opening 54 of the wrapping layer 53 is not increased during use of the diaper, and the absorber 5 is deformed, so that the diaper is deformed and the comfort of the wearer is affected.
Referring to fig. 7, the SMS nonwoven fabric at the sealing layer 55 is composed of an S layer, an M layer, and an S layer sequentially distributed from top to bottom. Wherein, the S layers of the upper layer and the lower layer of the M layers can be respectively arranged into a plurality of layers. The sealing layer 55 made of SMS nonwoven fabric or the like may form a double water-blocking functional layer in the diaper thickness direction with the water-repellent backsheet 2. The SMS nonwoven of the sealing layer 55 is preferably arranged with a basis weight in the interval 8-13 gsm. More preferably, the basis weight is set to 10gsm and the M layer in the SMS nonwoven is set to 6gsm.
Referring to fig. 5-6, according to a preferred embodiment, the water-locking layer of the present invention includes a first water-locking layer 51A, a second water-locking layer 51B, and a third water-locking layer 51C, which are sequentially distributed from inside to outside. The water-blocking layer is made of fluff pulp, high-molecular water-absorbing resin particles and the like. The ratio of the water-absorbent polymer particles in the first water-blocking layer 51A, the second water-blocking layer 51B, and the third water-blocking layer 51C increases in order. The hydrophilicity of the three water-blocking layers 51A, 51B, and 51C decreases in order from the direction closer to the coating layer 53 to the direction away from the coating layer 53, so that the liquid diffuses more easily from the water-permeable surface layer toward the inside of the water-blocking layers, ensuring the surface layer to be dry.
Preferably, the polymer water-absorbent resin particles of the first water-blocking layer 51A account for 40% -60% of the total weight in the first water-blocking layer 51A; the polymer water-absorbent resin particles of the second water-blocking layer 51B account for 50% -70% of the total weight of the second water-blocking layer 51B; the polymer water absorbent resin particles of the third water-blocking layer 51C account for 60% -80% of the total weight in the third water-blocking layer 51C. The high molecular water-absorbing resin particles in the 3 water-locking layers 51A, 51B and 51C ensure that the absorption rate of the physiological saline is not less than 60g/g (which means that 60g of physiological saline can be absorbed per gram of substance), the centrifugal water-retaining capacity is more than or equal to 38g/g (which means that 38g of physiological saline can be locked per gram of substance under the centrifugal dehydration condition), and the absorption rate under the load of 1.9kpa is not less than 30g/g (which means that 30g of physiological saline can be absorbed per gram of substance).
The first, second and third water-locking layers 51A, 51B and 51C contain ES fibers, and thus, the three water-locking layers 51A, 51B, 51C may be fixed to each other by multi-point adhesion using heat fusion of the ES fibers to form a point-adhered structure. Compared with the structure that the layers are adhered to each other by using the hot melt adhesive in the prior art, the ES fiber hot melt allows the point adhesion structure formed by adhering the layers to each other in a plurality of pairs of point-shaped areas opposite to each other, the layers cannot be blocked by the hot melt adhesive layer with weak air permeability and water permeability and high hardness, and the air permeability, the water permeability and the softness of the water locking layer are obviously improved.
Referring to fig. 1-2, as a diaper, in the diaper of the present preferred embodiment, a structure for ensuring that it can be ensured to be worn is: one end of the main body 100 is provided with a front waist patch 7, the other end is provided with a side wing 4, and the side wing 4 is matched with the front waist patch 7 so that the diaper can be worn. The lateral wings 4 have a different color from the main body 100, and the color may be blue, green, yellow, or the like. The side flaps 4 are preferably spun-bonded nonwoven fabrics, the color of which is formed by adding color bases. The side flaps 4 are provided with a higher degree of identification after being colored differently from the main body 100, so that people can easily identify the front and rear parts of the diaper, and the front and rear inversion of the diaper during the use of the diaper by a wearer is avoided.
An elastic waistline 10 is also provided at substantially the same position along the length direction A-A as the side flap 4, and the elastic waistline 10 provides a certain elasticity when the side flap 4 is attached to the front waist panel 9, ensuring a strong binding feeling to the waist of a wearer such as an infant. Referring to fig. 1, according to a preferred embodiment, the elastic waist circumference 10 includes a first elastic region, a second elastic region, and a third elastic region, each extending in the transverse direction and sequentially distributed from the crotch region toward the edge region in the longitudinal direction. The first elastic region, the second elastic region and the third elastic region have different elasticity, so that the elastic waistline 10 formed by the elastic regions can be attached to different positions of the waist of the wearer. The elastic waistline 10 composed of a plurality of elastic regions cooperates with the front waist patch 7 and the side wings 4 to enable the diaper according to the invention to be more matched with the body shape of a wearer.
In the example of fig. 1, the first elastic region is constituted by 2 elastic strands at a position to the left of the elastic waist circumference 10 of fig. 1; the second elastic region is composed of 3 elastic strips at the middle position of the elastic waistline 10; the third elastic region is formed by 2 elastic strips at the right side of the elastic waist line 10. It will be appreciated that, according to the inventive concept of the present application, the number of elastic strips in each elastic zone may be suitably modified in order to ensure that the pant diaper fits around the waist of wearers having different body types.
Preferably, the ratio of the length of the first elastic region, the second elastic region, and the third elastic region in the natural state to the length in the maximum stretched state is set to 2, 1.8, 2.2, respectively. The stretchable length of the different elastic zones may be achieved by providing elastic strips having different elasticity and/or length.
Referring to fig. 1-2, in the present invention, the outer edge positions along the left and right sides of the longitudinal direction A-A of the diaper main body 100 are also provided with the containment vessel 3 symmetrically along the center, and the containment vessel 3 is provided with the containment vessel elastic body 9 such as rubber strings along the longitudinal direction A-A thereof. By means of the guard elastic body 9 and the guard 3, the diaper can be better maintained in the crotch of an infant, the diaper is prevented from being displaced, and urine or the like is prevented from being ejected or oozed from the side of the diaper.
Preferably, the main body 100 is further provided with a diaper display band 12. By means of the diaper display belt 12, one can easily distinguish the content of foreign matter such as urine on the diaper to determine whether replacement is necessary.
In order to further ensure that foreign matter such as urine overflows or spouts from the diaper side portion, leg elastic bodies 8 are further provided along the outer edge side of the longitudinal direction A-A of the main body 100. The leg elastic body 8 is located closer to the side end portion of the main body 100 than the sheath elastic body 9. When the double elastic bodies are provided, the degree of tension of the guard elastic bodies 9 and the leg elastic bodies 8 can be appropriately reduced under the condition that foreign matters such as urine are not overflowed from the side portions, and thus the tight constraint feeling of the elastic bodies on infants can be avoided.
For the cover 53 of the present invention, it is preferably a hot air nonwoven fabric having a basis weight of not less than 20gsm and prepared using a plurality of hydrophilic fibers, which means fibers whose surface hydrophilic finish does not lose hydrophilicity even after a plurality of washings with a liquid. As another preferred embodiment, the coating layer 53 may also be a spun-laced nonwoven fabric having a basis weight of not less than 30gsm and prepared from viscose and hydrophilic polyester, wherein the hydrophilic polyester accounts for 60-80% of the coating layer 53 by weight.
The conductive layer 52 of the absorber 5 is preferably made of fluff pulp, ES fibers, or the like. The conductive layer 52 is preferably arranged to constitute 3-10% by weight of the absorbent body 5. After the conductive layer 52 is provided to contain ES fibers, a spot-adhered structure can be formed between the conductive layer 52 and the third water-blocking layer 51C, and thus the air permeability and water permeability of the diaper can be further improved.
According to the above, the upper water permeable surface layer 12, the lower water permeable surface layer 13, the coating layer 53, and the water blocking layer have successively increased hydrophilicities, and the upper water permeable surface layer 12 and the lower water permeable surface layer 13 have lower hydrophilicities, and the coating layer 53 and the water blocking layer have higher hydrophilicities. According to the conventional top sheet, liquid impurities such as urine and the like are quickly diffused along the surface of the top permeable top sheet 12 after contacting the top permeable top sheet 12, and then gradually permeate toward the absorbent core, so that the top sheet is easy to wet. According to the diaper provided as above, the lower material has a hydrophilic property superior to that of the upper material, and liquid impurities such as urine and the like can rapidly permeate down the water permeable surface layer 13 in a smaller area after contacting the upper water permeable surface layer 12 (i.e., the liquid impurities pass through the water permeable surface layer 1 in a "point-permeation" manner) and then permeate in a farther side direction (toward the absorber 5), and the liquid impurities are only present on a small portion of the surface of the water permeable surface layer 1 in a very small amount, so that the water permeable surface layer 1 according to the present invention has a dry, smooth characteristic.
Compared with a conventional paper diaper with a main body containing no fluff pulp and containing hot melt adhesive, the paper diaper has the main body containing fluff pulp and an absorber containing no hot melt adhesive, and the absorption performance, water locking performance, air permeability, softness and the like of the paper diaper are obviously improved. Referring to fig. 8-12, various performance parameters of a conventional diaper and a diaper according to example 1 of the present application are shown. In the water permeable surface layer of the diaper according to the present application corresponding to fig. 8 to 12, the upper water permeable surface layer 12 comprises 1.5D fine fiber with a basis weight of 9.3gsm and skin-friendly fiber with a basis weight of 0.7gsm, and the lower water permeable surface layer comprises 2.0D non-skin-friendly common fiber with a basis weight of 12 gsm; the cover 53 is a multiple hydrophilic hot air nonwoven having a basis weight of 20 gsm; the seal layer 55 is an SMS nonwoven fabric having a basis weight of 12 gsm; the first water-locking layer, the second water-locking layer and the third water-locking layer all comprise fluff pulp with the basis weight of 9gsm, ES fibers with the basis weight of 6gsm and super absorbent resin particles (SAP) with the basis weight of 55 gsm; the conductive layer comprises fluff pulp having a basis weight of 9gsm and ES fibers having a basis weight of 6 gsm; the thickness of the diaper is 2.96mm. Referring to fig. 8, compared with the conventional diaper, the water locking capacity of the diaper of the application can be improved by about 26%, and referring to fig. 9 and 10, the normal pressure and pressurized rewet amount of the diaper of the application can be remarkably reduced; referring to fig. 11, the absorber utilization of the diaper according to the present application can be significantly improved, wherein the absorber utilization represents the ratio of the length of the absorber that absorbs liquid to the entire length of the absorber after 3 times of absorption of the diaper; referring to fig. 12, the surface wetted length of the water permeable facing 1 of the present application can be reduced by about 39% compared to the conventional facing of the prior art. Meanwhile, according to the absorber composed of the cover 53, the conductive layer 52, and the water-blocking layer of the above form, since it is no longer using a bulky nonwoven fabric, the overall thickness of the diaper can be reduced from 3.52mm to 2.96mm.

According to fig. 14, in the diaper using the coating layer of the multiple hydrophilic hot air nonwoven fabric, the smaller the opening width and the smaller the basis weight, the lower the absorber utilization ratio of the diaper, but the absorber utilization ratio thereof can be kept at a high level (73% or more); the absorber utilization of the paper diaper (example 4) using the coating layer of the spun-laced nonwoven fabric was significantly lower than that of the paper diaper using the coating layer of the multi-time hydrophilic hot air nonwoven fabric.
For the water-repellent backing layer 2 of the present invention, it may be made of a PE film, a general water-repellent nonwoven fabric, or the like. Wherein the ventilation quantity of the PE film is in the range of 5000-6000 g/(m 2.24 h), and the common water-repellent non-woven fabric is hot air non-woven fabric with the basis weight of not less than 20gsm or SS non-woven fabric with the basis weight of not less than 15 gsm.
