An antibacterial layer is arranged on one side of the TPU base layer. A printing layer is arranged on the side of the antibacterial layer away from the TPU base layer. A stretch layer is arranged on the side of the TPU base layer away from the antibacterial layer. A skin-friendly layer is arranged on the side of the stretch layer away from the TPU base layer.
[0005] In the above scheme, the upper parts of the front panel and the rear panel are fixedly connected through an elastic belt.
[0006] In the above scheme, a cotton thickening layer is arranged on the inner side of the crotch panel.
[0007] In the above scheme, the antibacterial layer is a bamboo charcoal fiber layer.
[0008] In the above scheme, the stretch layer is a modal fiber layer.
[0009] In the above scheme, the skin-friendly layer is a pure cotton fiber layer.
[0010] The advantages and beneficial effects of the present utility model are as follows: The present utility model provides a high-elasticity TPU seamless underwear with an integrated seamless panel design, which can effectively avoid the exposure of underwear marks, improve the wearing aesthetics of the underwear, the antibacterial layer effectively increases the antibacterial performance of the underwear, the printing layer increases the aesthetics of the underwear, the elastic layer increases the antibacterial performance of the underwear, and the skin-friendly layer effectively increases the wearing comfort of the underwear. This kind of underwear has a simple structure, good antibacterial ability, strong elasticity, and the integrated structure effectively improves the wearing comfort. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will further describe the specific embodiments of the present utility model with reference to the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.
[0018] As Figure 1-2As shown in the figure, the utility model is a high-elastic TPU seamless underwear, which includes a front panel 1 and a rear panel 2. The front panel 1 and the rear panel 2 are connected and communicated through a crotch panel 3. The front panel 1, the rear panel 2 and the crotch panel 3 are integrally formed. The integrally seamless panel design can effectively avoid the exposure of underwear marks and improve the wearing aesthetics of the underwear. The front panel 1, the rear panel 2 and the crotch panel 3 have the same structure. The front panel 1 includes a TPU base layer 11. An antibacterial layer 12 is provided on one side of the TPU base layer 11. The setting of the antibacterial layer 12 effectively increases the antibacterial performance of the underwear. A printing layer 13 is provided on the side of the antibacterial layer 12 away from the TPU base layer 11. The printing layer 13 increases the aesthetics of the underwear. A stretch layer 14 is provided on the side of the TPU base layer 11 away from the antibacterial layer 12. The stretch layer 14 increases the overall elasticity of the underwear. A skin-friendly layer 15 is provided on the side of the stretch layer 14 away from the TPU base layer 11. The setting of the skin-friendly layer 15 effectively increases the wearing comfort of the underwear.
[0019] The upper parts of the front panel 1 and the rear panel 2 are fixedly connected through an elastic belt 4.
[0020] A cotton fabric thickening layer 5 is provided on the inner side of the crotch panel 3. The cotton fabric thickening layer 5 increases the comfort of the underwear at the crotch.
[0021] The antibacterial layer 12 is a bamboo charcoal fiber layer. Bamboo charcoal fiber has the characteristics of moisture absorption, air permeability, antibacterial and bacteriostatic, warm in winter and cool in summer, and green environmental protection.
[0022] The stretch layer 14 is a modal fiber layer. The modal fiber layer has good elasticity, thorough moisture absorption, good color fastness. Compared with pure cotton, it is more comfortable to wear and does not have the disadvantages of easy fading and yellowing of pure cotton clothing.
[0023] The skin-friendly layer 15 is a pure cotton fiber layer. The pure cotton fiber layer has the characteristics of moisture absorption, warmth retention, heat resistance, alkali resistance and hygiene, and its moisture absorption and heat resistance are better, improving the comfort of wearing.
[0024] Specifically, in the utility model, the integrally seamless panel design can effectively avoid the exposure of underwear marks and improve the wearing aesthetics of the underwear. The setting of the antibacterial layer 12 effectively increases the antibacterial performance of the underwear. The printing layer 13 increases the aesthetics of the underwear. The stretch layer 14 increases the overall elasticity of the underwear. The setting of the skin-friendly layer 15 effectively increases the wearing comfort of the underwear.
[0025] The above are only the preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
