Description

Technical Field

[0001] This utility model belongs to the field of underwear technology, specifically relating to a seamless men's underwear. Background Technology

[0002] In traditional underwear manufacturing, fabric is cut into components such as the front panel, back panel, and waistband, which are typically connected and secured using sewing techniques. However, this sewing process leaves seams on the underwear. These seams affect the smoothness of the underwear's surface and can cause friction against the skin during wear, leading to discomfort. Furthermore, these seams can become potential breeding grounds for bacteria, posing a risk to personal hygiene. Additionally, this process is inefficient, relies heavily on manual experience, and hinders the development of automated production.

[0003] Therefore, how to improve the manufacturing process of underwear and enhance wearing comfort is the technical problem that this utility model aims to solve. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a seamless men's underwear that improves both wearing comfort and production efficiency. Seamlessly connecting the various modules of the underwear eliminates the need for stitches, preventing skin friction and discomfort caused by seams, and providing a smoother wearing experience. The production process reduces heavy manual sewing steps, facilitating the automation of the production line. The three-dimensional front panel features a staggered design with an inner and outer layer that seamlessly connects to the front of the underwear, resulting in strong overall stability and preventing the seamless joints from tearing under external force.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a seamless men's underwear, including a pant body, a waistband (3), a crotch bottom (4), and a three-dimensional front crotch (5). The pant body is made of a single piece of fabric. The pant body includes a front part (1) and a back part (2). The three-dimensional front crotch (5) is composed of a front crotch inner layer (51) and a front crotch outer layer (52). The left and right edges of the front crotch inner layer (51) are seamlessly connected to the left and right edges of the inner surface of the pant body (1). The left and right edges of the front crotch outer layer (52) are seamlessly connected to the left and right edges of the outer surface of the pant body (1). The left and right edges of the front crotch inner layer (51) and the front crotch outer layer (52) are in different positions, so that the front crotch inner layer (51) and the front crotch outer layer (52) are staggered and seamlessly connected to the front part (1) of the pant body.

[0006] Furthermore, the left and right edges of the front panel (52) extend outward or contract inward, so that the front panel inner layer (51) and the front panel (52) are staggered and seamlessly connected to the front part (1) of the pants. This makes the overall stability of the underwear strong, and the seamless connection is not easily torn by external force.

[0007] Furthermore, the seamless connection is formed by multiple dot-shaped adhesive layers evenly distributed.

[0008] Furthermore, the diameter of the dotted adhesive layer is between 1 mm and 5 mm, and the spacing between the dots is between 5 mm and 20 mm.

[0009] Furthermore, the dotted adhesive layer is formed from a special adhesive with high viscosity and fast drying properties.

[0010] Furthermore, the three-dimensional front fender (5) is formed by a machine hot stamping process to create a three-dimensional bulging structure.

[0011] Furthermore, the three-dimensional bulging structure is formed by multiple hot stamping points under high temperature and pressure, with the diameter of each hot stamping point between 2mm and 10mm and the spacing between the hot stamping points between 5mm and 30mm.

[0012] Furthermore, the waistband (3) is seamlessly connected to the body of the pants.

[0013] Furthermore, the crotch bottom (4) is seamlessly connected to the bottom edge of the front part (1), the back part (2), and the three-dimensional front crotch part (5) of the pants respectively.

[0014] The beneficial effects of the above technical solution are as follows: This utility model provides a seamless men's underwear that improves both wearing comfort and production efficiency. Seamlessly connecting the various modules of the underwear avoids the generation of stitches, preventing skin friction and discomfort caused by stitches, and providing a smoother wearing experience for the user. The production process reduces heavy manual sewing steps, which is conducive to the automation of the production line. The three-dimensional front panel, with its staggered inner and outer layers seamlessly connected to the front of the pant body, ensures strong overall stability of the underwear, and the seamless connection is not easily torn by external forces.

[0015] During the production process, the waistband (3) can be seamlessly connected to the body of the pants first, then the inner layer (51) and outer layer (52) of the front crotch can be seamlessly connected to the inner and outer sides of the front part (1) of the pants body, respectively. Then, the crotch bottom (4) can be seamlessly connected to the bottom edge of the front part (1), the back part (2), and the three-dimensional front crotch part (5). Finally, a three-dimensional raised structure is formed by machine hot stamping. The entire production process is convenient, easy to divide labor, facilitates the improvement of production efficiency, promotes the development of production automation, and also improves product quality and enhances product comfort.

[0016] Traditionally, defective underwear produced using traditional sewing methods can only be recycled by shredding. However, the underwear described in this application, and the process of securing the underwear during production, can be disassembled to its original state if necessary. Attached Figure Description
