Description

Technical Field

[0001] The present invention relates to the technical field of sanitary products, and in particular to a seamless and comfortable waist structure and a trouser-type absorbent. Background Art

[0002] During use, existing diapers often have a waistline or three-dimensional guard that does not fit the user well due to the different weights and body shapes of the users, resulting in marks or falling off.

[0003] After searching, it is known that in the prior art, for example, patent CN202220859685.5 discloses a fine-denier spandex elastic waist waist-tie type diaper, including a diaper body and an elastic waist, the diaper body includes a surface layer, an absorption layer and a bottom layer, the bottom layer is provided with an upwardly protruding rear leakage prevention wall at one end close to the rear waist, the elastic waist includes a front waist and a rear waist, the two ends of the bottom layer are respectively connected to the front waist and the rear waist, the front waist and the rear waist are both double-layer structures, the front waist is sandwiched with a first spandex layer, the rear waist is sandwiched with a second spandex layer, and a third spandex layer is provided between the bottom layer and the absorption layer. The above-mentioned fine-denier spandex elastic waist waist-tie type diaper also has the following defects in practical applications:

[0004] The elastic waistband includes a front waistband and a back waistband, both of which are double-layer structures, a first spandex layer is sandwiched in the front waistband, and a second spandex layer is sandwiched in the back waistband. That is, both the front waistband and the back waistband are sandwiched with a layer of spandex through a double-layer structure. If too few spandex threads are set in this structure or the spandex threads are set in an inappropriate position, it will cause the waistband to fall off during use. To solve this problem, it is necessary to increase the number of spandex threads or use high-denier spandex threads. Increasing the number of spandex threads can increase the number of sandwiched spandex threads, but this will cause the entire waistband structure to have greater elasticity, which is easy to produce strangulation marks during use; using high-denier spandex threads can improve the resilience of the overall waistband structure, but high-denier spandex threads feel harder, making them not comfortable to use.

[0037] like Figure 1 - Figure 2 As shown, a seamless and comfortable waist structure disclosed in the present invention comprises a first waist layer 10, a first elastic layer 20, a second waist layer 30, a second elastic layer 40 and a third waist layer 50 which are sequentially stacked and connected from the inside to the outside; that is, when in use, the first waist layer 10 is a layer close to the skin, and the third waist layer 50 is a layer away from the skin;

[0038] The first elastic layer 20 is provided with a plurality of first elastic bodies 201 extending along the length direction, and the plurality of first elastic bodies 201 are arranged in an interval arrangement along the height direction;

[0039] The second elastic layer 40 is provided with a plurality of second elastic bodies 401 extending along the length direction, and the plurality of second elastic bodies 401 are arranged in an interval arrangement along the height direction;

[0040] The first elastic body 201 and the second elastic body 401 are both fine denier spandex yarns;

[0041] By setting the waist structure to have a double elastic layer, and the elastic layer has a plurality of elastic bodies arranged at intervals, compared with a structure with only one layer of elastic body, the contact area between the elastic layer and the skin can be increased while meeting the required elastic force, so that the pressure on the skin is reduced, and it is softer and more comfortable to wear; the first elastomer 201 and the second elastomer 401 use fine denier spandex yarn to make the waist structure softer. Compared with the use of coarse denier spandex yarn, it can greatly reduce the pressure on the skin and reduce the situation where the coarse denier spandex yarn causes marks on the skin, so that there is a seamless and comfortable experience when wearing.

[0042] Furthermore, in this embodiment, the first elastic body 201 and the second elastic body 401 are staggered;

[0043] The two layers of elastic bodies are staggered so that the waist structure can stretch and shrink more evenly, avoiding local excessive stretching or shrinkage, thereby improving wearing comfort; it can also increase the flexibility and adaptability of the waist structure, making it better fit the user's body shape and providing better support effect;

[0044] In actual production operations, the smaller the spacing between fine-denier spandex yarns, the higher the precision requirements for production equipment. Limited by the limitations of the gluing equipment, under existing conditions, the gluing equipment can currently achieve a minimum spacing of 2 mm between the axes of two adjacent fine-denier spandex yarns. As mentioned above, the first elastomer 201 and the second elastomer 401 are both fine-denier spandex yarns. The elasticity of a single fine-denier spandex yarn is less than that of a single thick-denier spandex yarn. When the height of the waist structure is fixed, a certain elasticity needs to be met, and the number of fine-denier spandex yarns must be increased. If all fine-denier spandex yarns are arranged in one elastic layer, the spacing between the axes of two adjacent fine-denier spandex yarns will be less than 2 mm. mm, so a two-layer elastic layer structure with a first elastic layer 20 and a second elastic layer 40 is set, and the fine denier spandex yarns are arranged at intervals along the height direction. If the fine denier spandex yarns of the two elastic layers are stacked, the waist structure will have uneven elasticity, so the fine denier spandex yarns of the two elastic layers are staggered, that is, the first elastomer 201 and the second elastomer 401 are staggered. Such an arrangement makes the distance between the axes of two adjacent fine denier spandex yarns in the same layer not less than 2mm, which can meet the minimum spacing requirement for sizing, and can also meet the elasticity required by the waist structure. The elasticity of the entire waist structure is evenly distributed, thereby improving the wearing comfort.

[0045] Furthermore, in the present embodiment, the specification of the fine denier spandex yarn is 40dtex to 180dtex. Compared with the spandex yarn of 400dtex to 800dtex, the spandex yarn of 40dtex to 180dtex has a softer resilience when in contact with the skin, exerts less pressure on the skin, and is less likely to cause marks.

[0046] Furthermore, in this embodiment, the axial center spacing between adjacent first elastic bodies 201 and second elastic bodies 401 in the height direction is 1 to 3 mm, and the optimal spacing is 1 mm.

[0047] Furthermore, in this embodiment, the first waist layer 10, the second waist layer 30 and the third waist layer 50 are all non-woven fabrics;

[0048] Non-woven fabrics can be spunbond non-woven fabrics. Spunbond non-woven fabrics are also called spunbond fabrics or meltblown fabrics. They are a type of non-woven fabric. They are composed of two main processes: spinning and melt-blowing. They have the advantages of strong coverage, good air permeability, high softness, high strength, strong adjustability, good processability, and biodegradability.

[0049] Furthermore, in this embodiment, the weight of the first waist layer 10 and the third waist layer 50 are both 4-25 gsm, and the optimal weight is 15 gsm;

[0050] The weight of the second waist layer 30 is 4-6 gsm, and the most preferred weight is 5 gsm.

[0051] Furthermore, in this embodiment, the thickness of the first waist layer 10 and the third waist layer 50 is greater than the thickness of the second waist layer 30;

[0052] As can be seen from the above, the first waist layer 10 , the second waist layer 30 and the third waist layer 50 are all non-woven fabrics, so the non-woven fabric selected for the second waist layer 30 is thinner than the non-woven fabric selected for the first waist layer 10 and the third waist layer 50 .

[0053] Furthermore, in this embodiment, the thickness of the first waist layer 10 and the third waist layer 50 are both H1, satisfying H1≤0.1 mm;

[0054] The thickness of the second waist layer 30 is H2, satisfying H2≤0.1 mm;

[0055] The thickness of the first elastic layer 20 and the second elastic layer 40 are both H3, satisfying H3≤0.1 mm;

[0056] From the above, it can be seen that the thickness of the first waist layer 10 and the third waist layer 50 is greater than the thickness of the second waist layer 30, so in actual application, the thickness H2 of the second waist layer 30 is less than the thickness H1, and the total thickness H of the first waist layer 10, the first elastic layer 20, the second waist layer 30, the second elastic layer 40 and the third waist layer 50 satisfies: H≤0.5mm.

[0057] Furthermore, in this embodiment, the first waist layer 10, the first elastic layer 20, the second waist layer 30, the second elastic layer 40 and the third waist layer 50 are stacked and bonded in sequence; hot melt adhesive can be selected for bonding.

[0058] The present embodiment also proposes a pants-type absorbent, including an absorbent body 60. The pants-type absorbent includes the seamless and comfortable waist structure as described above. Both ends of the absorbent body 60 are connected to the seamless and comfortable waist structure to form a front waist 70 and a rear waist 80. With the seamless and comfortable waist structure, the front waist 70 and the rear waist 80 of the pants-type absorbent have a seamless and comfortable effect.

[0059] In summary, a seamless and comfortable waist structure comprises a first waist layer 10, a first elastic layer 20, a second waist layer 30, a second elastic layer 40 and a third waist layer 50 which are sequentially stacked and connected from the inside to the outside; the first elastic layer 20 is provided with a plurality of first elastic bodies 201, and the plurality of first elastic bodies 201 are arranged at intervals along the height direction;

[0060] The second elastic layer 40 is provided with a plurality of second elastic bodies 401, and the plurality of second elastic bodies 401 are arranged at intervals along the height direction; the first elastic body 201 and the second elastic body 401 are both fine denier spandex yarns; the first elastic body 201 and the second elastic body 401 are arranged in a staggered manner. The above structure allows the waist structure to be more uniform when stretched and contracted, avoiding local excessive stretching or contraction, thereby improving the wearing comfort; it can also increase the flexibility and adaptability of the waist structure, so that it can better fit the user's body shape; and under the condition of meeting the required elastic force, the contact area between the elastic layer and the skin can be increased, so that the pressure on the skin is reduced, so that it is softer and more comfortable to wear.

[0061] A pant-type absorbent includes an absorbent body 60, the pant-type absorbent includes the seamless comfortable waistline structure as described above, and both ends of the absorbent body 60 are connected to the seamless comfortable waistline structure to form a front waistline 70 and a rear waistline 80. The above structure makes the pant-type absorbent have a seamless and comfortable effect when worn.
