[0002] Underwear is in direct contact with the human body, which directly affects the comfort of the human body. In particular, underwear is in close contact with the human body, which has the greatest impact on the comfort of the human body. The bottom wave fabric of traditional men's underwear is in the closest contact with the human body. Due to the poor ventilation of the bottom wave and crotch, the bottom wave and crotch fabric stick to the human body for a long time, resulting in increased humidity of the bottom wave and crotch fabric, causing discomfort to the human body, and there is a risk of causing diseases in the crotch tissue and surrounding areas.

[0003] At present, in terms of the design of men's underwear, people have adopted a variety of design methods to solve various problems. For example, the Chinese utility model patent with publication number CN208957024U discloses a men's antibacterial health underwear, including an underwear body, a waistband at one end of the underwear body, two trouser legs at the other end, a circle of edging cloth sewn on the waistband, and a circle of elastic band between the edging cloth and the waistband; the underwear body is spliced ​​by the trouser body, the bottom wave and the front center, the bottom wave and the front center are respectively sewn in the middle of the trouser body, and the bottom wave is located at the lower part of the front center; the bottom wave and the front center are both double-layer structures, including an inner layer and an outer layer respectively; the inner layers of the bottom wave and the front center are both made of antibacterial cloth, and the antibacterial cloth is blended from bamboo charcoal fiber, flax fiber and combed cotton fiber, and the outer layers of the bottom wave and the front center are both activated carbon filter cloth. The bottom wave of this patent is only provided with a plurality of breathable mesh holes on the outer layer.

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] In the present utility model, the descriptions involving "first", "second", "upper", "lower", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", "upper", "lower" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the technical solutions between the embodiments can be combined, they are all within the protection scope required by the present utility model.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0043] like Figures 1 to 3 As shown, a men's underwear with a bottom wave hole structure includes: a bottom wave 4, a front cloth 1, a back cloth 2 and a crotch 3. The crotch 3 is connected to the bottom wave 4. The front cloth 1 includes a first front piece and a second front piece, and the first front piece and the second front piece are connected to the crotch 3 and the bottom wave 4 on both sides. The back cloth 2 is connected to the first front piece and the second front piece on both sides, and the bottom is connected to the bottom wave 4. Figure 4 and Figure 5 As shown, the bottom wave 4 is provided with a plurality of ventilation holes 5, and the ventilation holes 5 include ventilation holes 51 and a raw material area 53, and the ventilation holes 51 and the raw material area 53 are connected by a welding area 52. The thickness of the ventilation holes 5 simultaneously satisfies the following formula (1):

[0044] T = b × A (1).

[0045] Wherein, T is the thickness of the welding zone 52, A is the thickness of the raw material zone 53, and the coefficient b satisfies b≤0.4.

[0046] The width Z of the weld zone 52 satisfies the following formula (2):

[0047] Z=c×T (2).

[0048] Wherein, the coefficient c satisfies 0.5≤c≤3.

[0049] The above structure forms underwear suitable for male ergonomics, satisfies the customer's comfort and improves the experience. On the basis of this structure, the above formula (1) and formula (2) are satisfied so that the thickness of the welded area 52 is moderate, and will not cause squeezing or other discomfort to the human body, further improving the customer's experience.

[0050] Furthermore, the vent holes 51 are realized by cold pressing, ultrasonic melting and trimming the raw materials using a mold that matches the design.

[0051] The welding area 52 of the ventilation hole 5 is realized by cold pressing ultrasonic melting and trimming the cut fabric using an ultrasonic processing method using a special ultrasonic mold suitable for the designed hole pattern, thereby improving the processing efficiency and ensuring the regularity of each ventilation hole 51.

[0052] Furthermore, a water washing test is performed after trimming to ensure that the welding area 52 and the raw material area 53 are firmly bonded.

[0053] After ultrasonic trimming, the air vents 51 do not show a product appearance quality defect of low bonding strength resulting in significant separation of the welded area 52 in the water washing test.

[0054] Furthermore, while satisfying formula (1), T≤0.3 mm. While satisfying formula (2), 0.1≤Z≤0.3 mm.

[0055] In order to ensure that the welded edge of the welded area 52 does not cause squeezing or other discomfort to the human body after the product is worn, the welded area 52 should not be too wide or too thick; at the same time, to ensure that the welded area 52 does not have obvious appearance quality defects after washing, the welded area 52 should not be too narrow or too thin. In order to improve the appearance and feel of the product, the welded area 52 of the air permeable hole 5 after cold pressing and ultrasonic melting is required to be distributed in the middle thickness position area of ​​the raw material area 53, satisfying the above formulas (1) and (2) while satisfying the trend range of T and Z, and achieving the above three functional and appearance quality requirements.

[0056] Furthermore, the plurality of ventilation holes 51 form a preset pattern.

[0057] The vent holes 51 may be irregular. In order to improve the aesthetics of the product, the vent holes 51 may form a certain pattern.

[0058] As another embodiment, each of the air holes 51 is a uniformly distributed circular hole. The diameter D of each hole is equal and satisfies the following formula (3):

[0059] D = e × (LD) (3).

[0060] L is the distance between two adjacent air holes 51 , and the coefficient e satisfies: 1.5≤e≤5.

[0061] The air holes 51 formed on the air hole positions 5 are functional areas for air circulation. Theoretically, the larger the air holes 51 are, the better the air circulation effect will be.

[0062] However, the bottom wave 4 is a functional component of the shorts product, and it is necessary to combine the wearing comfort, appearance, quality and life of the product, and then constrain the ventilation holes 51 according to the material structure and appearance requirements of the product cutting pieces to meet the comprehensive requirements of product breathability, comfort and beauty.

[0063] Furthermore, the distance W between each of the ventilation holes 5 near the edge of the bottom wave 4 raw material and the edge of the cut piece is ≥10 mm.

[0064] Ensure the strength of the edge of the bottom wave 4 to avoid being cracked from the ventilation hole 5.

[0065] Furthermore, the bottom wave 4 is a single piece or is formed by splicing at least two pieces.

[0066] The bottom wave 4 can be made of the cloth of the main piece, and can also be made by splicing the leftover scraps, which saves cloth and reduces waste.

[0067] Furthermore, the weight of the raw material of the bottom wave 4 is more than 60GSM. The raw material of the bottom wave 4 includes a nylon layer, and the mass proportion of the nylon layer is more than 60%.

[0068] Nylon has good strength, wear resistance, water absorption and elasticity. As the raw material of underwear, it can increase comfort.

[0069] Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the scope defined by the claims.
