Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure belong to the technical field of underpants, and particularly relate to an underpants. BACKGROUND

[0002] The main structure of the existing period underpants is that the crotch extends to the back piece to the waist, the crotch cloth is bonded with a film on the reverse side to achieve the purpose of preventing side leakage. However, most of them have the following disadvantages: the film on the crotch has no elasticity, and the film limits the stretch deformation of the crotch. The crotch with small stretch deformation limits the stretch deformation of the part of the underpants covered by the crotch. When the user wears the underpants, especially when bending over or squatting, the stretch deformation of the back waist side of the underpants under the limitation of the crotch is small, which makes the back waist of the underpants arch downward, thereby exposing part of the user's back waist or part of the user's buttocks, affecting the comfort of the user's buttocks, and further affecting the user's experience. CONTENT OF THE UTILITY MODEL

[0003] Embodiments of the present disclosure aim to at least solve one of the technical problems existing in the prior art, and provide an underpants.

[0032] like Figures 1 to 4 As shown, an embodiment of this disclosure provides an underwear 100, which includes an underwear body 10 and a crotch 20. Specifically, the crotch 20 is connected to the inside of the underwear body 10 and extends from the front side of the underwear body 10 to the upper rear edge of the underwear body 10. The crotch 20 includes a skin-friendly layer 21 and an elastic protective layer 22. The elastic protective layer 22 is disposed between the skin-friendly layer 21 and the underwear body 10. The elasticity of the elastic protective layer 22 is greater than or equal to the elasticity of the underwear body 10, and the elasticity of the skin-friendly layer 21 is greater than or equal to the elasticity of the underwear body 10.

[0033] The underpants 100 of the embodiments of the present disclosure comprises an underpants body 10 and a crotch 20, wherein the crotch 20 is connected to the inner side of the underpants body 10, the bottom plate has an upper edge extending from the front side of the underpants body 10 to the back side of the underpants body 10, the protection of the underpants body 10 is realized through the crotch 20, the wear of the underpants body 10 is reduced, and the service life of the underpants 100 is improved; specifically, the crotch 20 comprises a skin-friendly layer 21 and an elastic protection layer 22, the elastic protection layer 22 is arranged between the skin-friendly layer 21 and the underpants body 10, the skin-friendly layer 21 is in contact with the skin of the user, and the elastic protection layer 22 is used to prevent liquid from flowing to the underpants body 10, so as to prevent the underpants body 10 from being soaked by the liquid, so as to achieve the effect of protecting the underpants body 10, thereby avoiding that the liquid soaks other clothes through the underpants body 10; the elastic force of the elastic protection layer 22 is greater than or equal to the elastic force of the underpants body 10, when the underpants body 10 is subjected to a pulling force, the elastic protection layer 22 can be deformed by stretching together with the underpants body 10, so as to avoid that the elastic protection layer 22 limits the deformation by stretching of the underpants body 10, and the elastic force of the skin-friendly layer 21 is greater than or equal to the elastic force of the underpants body 10, when the underpants body 10 is subjected to a pulling force, the skin-friendly layer 21 can be deformed by stretching together with the underpants body 10, so as to avoid that the skin-friendly layer 21 limits the deformation by stretching of the underpants body 10, thereby ensuring that when the user bends over or squats while wearing the underpants 100, neither the elastic protection layer 22 nor the skin-friendly layer 21 limits the deformation by stretching of the underpants body 10, that is, the elastic protection layer 22 and the skin-friendly layer 21 are deformed by stretching together with the underpants body 10, so as to avoid that the back waist of the underpants 100 of the user appears to be downwardly curved, prevent the skin of the back side of the waist of the user from being exposed, improve the comfort of the buttocks and the waist of the user, and improve the use experience of the user.

[0034] In some embodiments of the present disclosure, the elastic force of the elastic protection layer is equal to the elastic force of the skin-friendly layer 21, and the elastic force of the skin-friendly layer 21 is equal to the elastic force of the underpants body 10, that is, the elastic force of the elastic protection layer 22, the elastic force of the skin-friendly layer 21 and the elastic force of the underpants body 10 are all equal. When the underpants body 10 is subjected to a pulling force, the elastic protection layer 22 connected to the inner side of the underpants body 10 is deformed by stretching together with the underpants body 10, the skin-friendly layer 21 connected to the inner side of the underpants body 10 is deformed by stretching together with the underpants body 10, and the deformation amounts of the elastic protection layer 22, the skin-friendly layer 21 and the underpants body 10 are the same, neither the elastic protection layer 22 nor the skin-friendly layer 21 limits the deformation amount of the underpants body 10, thereby avoiding that the back waist of the underpants 100 of the user appears to be downwardly curved, preventing the skin of the back side of the waist of the user from being exposed, and improving the comfort of the buttocks and the waist of the user.

[0035] In some other embodiments of the present disclosure, the elastic force of the elastic protective layer 22 can be greater than the elastic force of the skin-friendly layer 21, or the elastic force of the skin-friendly layer 21 is greater than the elastic force of the elastic protective layer 22. The embodiments do not specifically limit the elastic force of the elastic protective layer 22 and the elastic force of the skin-friendly layer 21, as long as the elastic force of the elastic protective layer 22 is not less than the elastic force of the underpants body 10, and the elastic force of the skin-friendly layer 21 is not less than the elastic force of the underpants body 10. In order to reduce the difficulty of preparation of the elastic protective layer 22 and the skin-friendly layer 21, and to ensure the fit of the elastic protective layer 22 and the skin-friendly layer 21, the elastic force of the elastic protective layer is equal to the elastic force of the skin-friendly layer 21, and the elastic force of the skin-friendly layer 21 is equal to the elastic force of the underpants body 10, which is a preferred solution.

[0036] In some embodiments of the present disclosure, the elastic protective layer 22 is a polyester amine layer, that is, the elastic protective layer 22 is prepared from polyester amine, specifically, the elastic protective layer 22 is prepared from polyester amine fiber material. The polyester amine fiber contains amino and ester groups in its chemical structure, has good elasticity and resilience. The polyester amine fiber has a polar group in its molecular structure, so that the internal structure of the fiber is stable and not easy to loosen and wrinkle, and it has good wrinkle resistance.

[0037] In some embodiments of the present disclosure, as shown in Figure 4 , the skin-friendly layer 21 and the elastic protective layer 22 have the same shape and equal size, so as to facilitate the sewing connection of the edges of the skin-friendly layer 21 and the edges of the elastic protective layer 22, improve the reliability of the connection of the skin-friendly layer 21 and the elastic protective layer 22, and at the same time, reduce the flash of the edge of the crotch 20.

[0038] In some embodiments of the present disclosure, the skin-friendly layer 21 and the elastic protective layer 22 are connected by adhesion, specifically, the side of the elastic protective layer 22 close to the skin-friendly layer 21 is coated with adhesive, and the elastic protective layer 22 is connected to the skin-friendly layer 21 by the adhesive. The skin-friendly layer 21 and the elastic protective layer 22 have the same shape and equal size, and the adhesion can make one side of the skin-friendly layer 21 completely fit one side of the elastic protective layer 22, and the edges of the skin-friendly layer 21 coincide with the edges of the elastic protective layer 22, thereby improving the reliability of the connection of the skin-friendly layer 21 and the elastic protective layer 22.

[0039] In some embodiments of the present disclosure, as shown in Figure 2 , Figure 5 and Figure 6 , the edges of the skin-friendly layer 21 and the edges of the elastic protective layer 22 are connected by the overlock 23, and the overlock 23 wraps the edges of the skin-friendly layer 21 and the edges of the elastic protective layer 22 by overlock thread, so that the edge of the crotch 20 is neat and clean without burrs, thereby improving the comfort of the crotch 20 and the user experience.

[0040] Specifically, the width of the overlock 23 is 0.3 cm. When the width of the overlock 23 is 0.3 cm, the overlock 23 can cover the raw edges of the edge of the crotch 20 completely, and ensure the cleanliness of the edge of the crotch 20.

[0041] In some embodiments of the present disclosure, as shown in Figure 1 and Figure 5 The crotch 20 is connected with the underpants body 10 through the zigzag overlock 30. Since the size of the crotch 20 is smaller than the size of the underpants body 10, the connection between the crotch 20 and the underpants body 10 can be achieved by overlocking the edges of the crotch 20 and the underpants body 10 through the zigzag overlock 30.

[0042] In some embodiments of the present disclosure, the zigzag overlock 30 covers part of the overlock 23, so as to ensure that the overlock 23 of the edge of the crotch 20 does not lift from the underpants body 10, improve the comfort of the crotch 20 of the user, and ensure the use experience of the user. At the same time, the overlock 23 of the edge of the crotch 20 makes the edges of the skin-friendly layer 21 and the elastic protective layer 22 more firm, and the zigzag overlock 30 covers part of the overlock 23, that is, the zigzag overlock 30 overlocks the part of the edge of the crotch 20 covered by the overlock 23 and the underpants body 10, that is, the zigzag overlock 30 overlocks the part of the edge of the crotch 20 connected most firmly and the underpants body 10, further improving the firmness of the connection between the crotch 20 and the underpants body 10.

[0043] In some embodiments of the present disclosure, the minimum distance between the zigzag overlock 30 and the edge of the crotch 20 is less than 0.3 cm, and the maximum distance between the zigzag overlock 30 and the edge of the crotch 20 is greater than 0.1 cm, that is, part of the zigzag overlock 30 covers the overlock of the edge of the crotch 20, and the other end of the zigzag overlock 30 extends away from the edge of the crotch 20, that is, the zigzag overlock 30 does not completely cover the overlock, reduces the repeated area of the zigzag overlock 30 and the overlock, improves the thickness of the connection between the edge of the crotch 20 and the underpants body 10, improves the comfort of the edge of the crotch 20, and further improves the use experience of the user. The minimum distance between the zigzag overlock 30 and the edge of the crotch 20 is less than 0.3 cm, which can ensure that the zigzag overlock 30, and the maximum distance between the zigzag overlock 30 and the edge of the crotch 20 is greater than 0.1 cm, so as to ensure that the zigzag overlock 30 does not completely cover the edge of the overlock 23 and can press the overlock 23, avoiding the overlock 23 from lifting.

[0044] Specifically, the width of the zigzag overlock 30 ranges from 0.3 cm to 0.6 cm with an interval of 0.1 cm. When the width of the zigzag overlock 30 ranges from 0.3 cm to 0.6 cm with an interval of 0.1 cm, the connection between the crotch 20 and the underpants body 10 can be achieved, and the width ranging from 0.3 cm to 0.6 cm with an interval of 0.1 cm can ensure the firmness of the connection between the crotch 20 and the underpants body 10.

[0045] It is to be understood that the above-mentioned embodiments are merely illustrative of the principles of the present disclosure and that numerous modifications and improvements can be effected thereto without departing from the spirit and scope of the disclosure.
