[0026] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example
[0027] Please see Figure 1-4This utility model provides a technical solution: a comfortable sanitary pant, including a diaper body 1. The diaper body 1 includes elastic waistband fabric 15 arranged at the front and back, and Velcro straps 16 distributed on the back elastic waistband fabric 15. An absorbent core is arranged between the two elastic waistband fabrics 15. The absorbent core includes a leak-proof bottom film 11, a surface non-woven fabric 12, and a core absorbent layer 13. Leak-proof and water-repellent fabrics 14 are arranged on both sides of the surface non-woven fabric 12. Elastic large tabs 151 are symmetrically connected to the outer edges of both sides near the back elastic waistband fabric 15. Each elastic large tab 151 is connected to a... Two small ear pieces are provided, which are arranged in a U-shape. Velcro 16 is distributed on the small ear pieces. The two elastic waistband fabrics 15 set at the front and back are connected on both sides by Velcro 16 to form a closed loop. The surface non-woven fabric 12 is attached to the leak-proof bottom film 11, the core absorbent layer 13 is located on the surface non-woven fabric 12, and the leak-proof water-repellent fabric 14 is integrally connected to the leak-proof bottom film 11 near the outer edges on both sides. When the two Velcro 16 are attached to the front side of the elastic waistband fabric 15, the width of the Velcro 16 on both sides is smaller than the width of the elastic waistband fabric 15. The large elastic ear piece 151 is a soft elastic fabric layer.
[0028] It should be noted that in this embodiment, the elastic waistband fabric 15 set at the front and back, together with the absorbent core, forms a structure that can better fit the curve of the human buttocks, providing more comprehensive coverage and effectively preventing side leakage. This design can reduce the gap between the diaper and the skin, and increase the stability and comfort of wearing.
[0029] Furthermore, the Velcro 16 is designed in a U-shape, with the distance between the outer edges on both sides being less than the width of the elastic waistband fabric 15. The U-shape structure makes it easier for the Velcro 16 to be aligned and attached to the elastic waistband fabric 15, reducing possible deviations during the attachment process. Since the Velcro 16 does not directly contact the skin but is connected through small tabs, it reduces skin irritation and increases the comfort of use. The U-shape design ensures uniform attachment and avoids curling problems caused by improper attachment.
[0030] Furthermore, the elastic waistband 15 is symmetrically connected with elastic large ear pieces 151 on both outer edges near the back side. The elastic large ear pieces 151 allow users to adjust the tightness of the diaper according to their personal needs, providing better fit and comfort. The design of the elastic large ear pieces 151 helps to maintain the stability of the diaper during use and reduce displacement.
[0031] The leak-proof and water-repellent fabric 14 is integrated and located on the outer edges of the leak-proof bottom film 11 near both sides. The leak-proof and water-repellent fabric 14 can further enhance the leak-proof performance of the diaper, especially in the inner thigh area, effectively preventing side leakage.
[0032] Please see Figure 2 , 3And 4, the leak-proof bottom membrane 11 includes a polyethylene waterproof layer and an auxiliary absorbent layer. The auxiliary absorbent layer is located on the polyethylene waterproof layer inside the leak-proof water-repellent fabric 14. The surface non-woven fabric 12 includes a surface covering layer, which is located on the auxiliary absorbent layer. The core absorbent layer 13 includes a super absorbent resin layer, a fluff pulp layer, and a diversion layer.
[0033] It should be noted that, in this embodiment, the core absorbent layer 13 includes a highly absorbent resin layer, a fluff pulp layer, and a flow guiding layer. The multi-layered core absorbent layer 13 can quickly absorb and lock in moisture, keep the surface dry, and improve the user's comfort. The design of the flow guiding layer helps to quickly disperse the liquid to the entire absorption area and reduce backflow.
[0034] The superabsorbent polymer (SAP) layer is the most critical part of the core absorbent layer 13. It can quickly absorb and lock in a large amount of water to prevent urine backflow.
[0035] The fluff pulp layer serves as a support material for SAP. Through the capillary effect, the fluff pulp helps absorb and distribute urine, thereby improving overall absorption efficiency.
[0036] The flow guiding layer is located above the core absorption layer 13. It utilizes the large aspect ratio of the hot air nonwoven material to guide the liquid to penetrate longitudinally, allowing more liquid to enter the absorption core layer.
[0037] The structural design of the surface non-woven fabric 12 and the core absorbent layer 13 is to provide excellent breathability, softness, absorbency and leak-proofness to meet the needs of different users.
[0038] Furthermore, the surface nonwoven fabric 12 includes a surface covering layer, which increases the softness of the diaper and improves comfort when in contact with the skin. The covering layer also provides additional protection and reduces friction and irritation.
[0039] The leak-proof bottom film 11 includes a polyethylene waterproof layer and an auxiliary absorbent layer. The auxiliary absorbent layer is located inside the leak-proof and water-repellent fabric 14 and is combined with the polyethylene waterproof layer to provide additional leak protection. This double-layer design enhances the overall durability and reliability of the diaper.
[0040] The working process of this utility model:
[0041] Before use, carefully inspect the diaper for any tears or defects to ensure it is intact. Lay the diaper flat on a clean, flat surface, ensuring it is fully unfolded without any folds or curls. Align the front of the diaper with the user's abdomen and the back with the back, ensuring the diaper is correctly positioned for a better fit to the body's curves. Gently pull the diaper up from front to back, ensuring it fits snugly against the body, but not too tightly to avoid discomfort. Align the U-shaped Velcro 16 with the front of the elastic waistband 15 and gently press to secure it. Ensure the width of the Velcro 16 on both sides is less than the width of the elastic waistband 15 to guarantee stability and evenness of the adhesion. After putting on the diaper, check that it fits the body's curves, especially the inner thighs and buttocks area, ensuring there are no gaps or wrinkles to prevent side leakage. Finally, gently smooth the diaper with your hands to ensure it fits smoothly and comfortably against the body.
[0042] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
