[0023] Combine the following Figures 1 to 3 The technical solution of the present invention is further illustrated by specific embodiments.

[0024] like Figure 1 and Figure 1 The highly absorbent and quick-to-wear and -take-off underpants-type article shown comprises: a waist member 1 and an absorbent insert 2, wherein the waist member 1 comprises a front waist portion 12, a crotch portion 13 and a rear waist portion 11, wherein the crotch portion 13 is arranged between the front waist portion 12 and the rear waist portion 11 to form an underpants-type structure, and the front waist portion 12, the crotch portion 13 and the rear waist portion 11 can be made of non-woven fabrics, are disposable, and have low cost.

[0025] In this embodiment, the two ends of the front waist portion 12 are directly or indirectly connected to the two ends of the back waist portion 11 to form a ring-shaped waist structure. The two ends of the back waist portion 11 are provided with fastening portions 18 extending to the two ends of the front side of the front waist portion 12, and the fastening portion 18 and the end of the back waist portion 11 adopt an integrated structure or a hot-pressed connection structure.

[0026] like Figure 2 As shown, a second bristle-like locking portion 17 is provided on the side of the fastening portion 18 corresponding to the front side of the front waist portion 12, and a second fluff portion corresponding to the second bristle-like locking portion 17 is provided on the front side of the front waist portion 12, so as to facilitate the connection between the fastening portion 18 and the two ends of the front side of the front waist portion 12, thereby realizing the restraint of the human waist and improving the wearing stability.

[0027] The absorbent insert 2 is arranged on the crotch portion 13, such as Figure 3 to Figure 5 As shown, the absorbent insert comprises an absorbent core 25, a front sheet 21 and a back sheet. The back sheet is arranged on the back of the front sheet 21, and the edges are sealed by heat pressing.

[0028] In this embodiment, the back of the back sheet is provided with an outward protrusion, and a cavity 29 corresponding to the absorption core 25 is formed between the outward protrusion and the front sheet 21. The absorption core 25 is arranged in the cavity 29. The absorption core 25 can adopt a granular super absorbent polymer, which has good absorption of excreta such as urine and menstrual blood.

[0029] like Figure 3 As shown, the edge of the front sheet 21 is provided with pleats 22. The three-dimensional pleats 22 can increase the protection of the front sheet 21, prevent the excreta on the front sheet 21 from leaking outward, and facilitate the removal of the absorbent insert 2 by pinching the pleats 22. The front sheet 21 is made of hydrophilic nonwoven fabric, which has a good hydrophilic effect and can quickly deliver the excreta of the human body to the absorbent core 25, further avoiding the problem of side leakage.

[0030] As shown in Figure 2, an embedding groove corresponding to the convex portion is provided in the crotch portion 13 to position the convex portion. In addition, the design of the embedding groove is conducive to the expansion of the absorbent core 25 behind the back sheet, which can increase the capacity of the absorbent core 25, thereby improving absorbency.

[0031] In this embodiment, the outer protrusion includes a rectangular protrusion 23 extending longitudinally along the crotch portion 13 and arc protrusions 24 located at both ends of the rectangular protrusion 23. The diameter of the arc protrusion 24 is greater than the width of the rectangular protrusion 23, forming slightly larger outer protrusions at both ends, which can not only increase the capacity of the cavity 29 for the absorption core 25, but also improve the stability of the outer protrusion in the embedded groove.

[0032] like Figure 2 As shown, the embedding groove runs through the crotch portion 13 in the thickness direction, and the embedding groove includes a square groove 14 corresponding to the rectangular convex portion 23 and an arc groove 15 corresponding to the arc convex portion 24, which respectively position the rectangular convex portion 23 and the arc convex portion 24, and limit the movement of the arc convex portion 24 along the length direction of the rectangular convex portion 23, thereby improving stability after wearing.

[0033] In order to prevent the absorbent insert 2 from falling off, a first bristle-like locking portion 26 located outside the outer convex portion is provided on the back side of the back sheet, and a first fluff portion 16 corresponding to the first bristle-like locking portion 26 is provided around the embedding groove on the crotch portion 13. The first bristle-like locking portion 26 and the first fluff portion 16 form a Velcro structure to lock the absorbent insert 2, and the absorbent insert 2 can be removed and replaced separately, thereby reducing costs. There is no need to replace the waist member 1 when going out, and the operation is faster.

[0034] It is worth noting that the first fluff portion 16 and the second fluff portion can be the surface layer itself, or can be flannel provided on the surface layer for connecting with the first burr-type locking portion 26 and the second burr-type locking portion 17, such as a flannel structure corresponding to Velcro.

[0035] like Figure 5 As shown, the back sheet includes a waterproof and breathable membrane layer 27, which has good waterproof properties and prevents the excrement from leaking backwards. In addition, in this embodiment, the back sheet also includes a flexible non-woven fabric layer 28 located on the back of the waterproof and breathable membrane layer 27. The flexible non-woven fabric layer 28 improves the tactile comfort of the back sheet and protects the waterproof and breathable membrane layer 27, thereby preventing the waterproof and breathable membrane layer 27 from being worn out by contact with the human body or clothing, and has high safety.

[0036] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
