Description

Technical Field

[0001] The utility model relates to the technical field of underwear manufacturing, in particular to a pair of men's underwear with a seamless crotch structure. Background Art

[0002] In the traditional manufacturing process of underwear, the connection between the waistband and the trouser body is usually fixed by sewing technology or old-fashioned adhesive bonding. Although these methods can effectively connect the waistband and the trouser body, they have some obvious shortcomings.

[0003] Specifically, when sewing technology is used, stitches will be left on the underwear. These stitches may not only affect the aesthetics of the underwear, but also cause friction with the skin during wearing, causing discomfort to the user. In addition, stitches may also become a potential breeding ground for bacteria, which is not conducive to personal hygiene.

[0004] On the other hand, the old-fashioned glue method avoids the problem of sewing lines, but its bonding strength and durability are often questioned. Moreover, the glue is directly applied to the inside of the underwear, in direct contact with the skin, which may cause allergic reactions or discomfort.

[0005] Furthermore, when forming a bulging three-dimensional structure at the waistband, the traditional process often requires sewing, which not only increases production costs and process complexity, but also has the same problems caused by sewing lines.

[0006] Therefore, how to improve the connection between the waistband and the body of the underwear and solve the problem of realizing the three-dimensional bulging structure of the waistband to improve wearing comfort, hygiene and durability has become a technical problem to be solved by the utility model. Utility Model Content

[0007] The technical problem solved by the utility model is to provide a men's underwear with a seamless crotch structure in view of the defects existing in the above-mentioned prior art, so as to solve the problems of wearing discomfort, hygienic hazards, weak adhesion and complex three-dimensional structure of the waistband in the underwear manufacturing process proposed in the above-mentioned background technology.

[0008] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0009] A men's underwear with a seamless crotch structure, comprising a men's underwear body, wherein the men's underwear body comprises a waistband part and a body part;

[0010] The waistband is connected to the body through a plurality of dot-shaped adhesive layers, wherein the dot-shaped adhesive layers are located in the overlapping area between the waistband and the body and are evenly distributed along the edge of the waistband to form a seamless connection structure;

[0011] The waistband has a three-dimensional bulging structure formed by a machine hot stamping process. The three-dimensional bulging structure is located in the central area of ​​the waistband so that the three-dimensional bulging effect of the waistband can be achieved without sewing.

[0012] As a further solution of the utility model, the dot-shaped glue layer is formed by a special glue with high viscosity and quick drying. The glue solidifies quickly after being dotted, ensuring a firm connection between the waistband and the body of the pants.

[0013] As a further solution of the utility model, the diameter of the dot-shaped glue layer is between 1 mm and 5 mm, and the spacing of the glue dots is between 5 mm and 20 mm to ensure the stability of the connection and the aesthetics of the underwear.

[0014] As a further solution of the utility model, the three-dimensional bulging structure is composed of a plurality of hot stamping dots, and these hot stamping dots form a regular convex pattern on the waistband area of ​​the underwear to achieve a three-dimensional effect of the waistband area.

[0015] As a further solution of the utility model, the hot stamping dots are formed on the waistband of the underwear by high temperature and pressure, the diameter of each hot stamping dot is between 2mm and 10mm, and the spacing between the hot stamping dots is between 5mm and 30mm.

[0016] As a further solution of the utility model, the arrangement of the dot-shaped adhesive layer and the three-dimensional bulging structure together realizes seamless connection and three-dimensional shaping of the waistband of the underwear, thereby improving the comfort and aesthetics of the underwear.

[0017] As a further solution of the utility model, the trouser body and the trouser waist are both made of soft and breathable fabrics to ensure wearing comfort and hygiene.

Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0027] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] See also Figure 1 In the embodiment of the utility model, a pair of men's underwear with a seamless crotch structure includes a men's underwear body 1, wherein the men's underwear body 1 includes a waistband portion 2 and a body portion 3;

[0029] The waistband part 2 is connected to the body part 3 by a plurality of dot-shaped adhesive layers 5. The dot-shaped adhesive layers 5 are located in the overlapping area between the waistband part 2 and the body part 3 and are evenly distributed along the edge of the waistband part 2 to form a seamless connection structure. The waistband part 2 has a three-dimensional bulging structure 4 formed by a machine hot stamping process. The three-dimensional bulging structure 4 is located in the central area of ​​the waistband part 2 so that the three-dimensional bulging effect of the waistband part 2 can be achieved without sewing.

[0030] The dotted glue layer 5 is formed by a special glue with high viscosity and quick drying, and the glue is quickly solidified after being dotted, ensuring a firm connection between the waistband part 2 and the body part 3. The diameter of the dotted glue layer 5 is between 1 mm and 5 mm, and the distance between the dots is between 5 mm and 20 mm to ensure the stability of the connection and the aesthetics of the underwear.

[0031] The realization of the three-dimensional bulging structure 4 can, for example, rely on the cooperation of multiple hot stamping points during hot stamping. These hot stamping points are applied to the waistband part 2 of the underwear in a uniform distribution through the action of high temperature and pressure. The diameter of each hot stamping point is controlled between 2mm and 10mm to ensure that the area of ​​action is neither too large nor too small, and the spacing between the hot stamping points is maintained between 5mm and 30mm to achieve the best distribution effect, so that the hot stamping points not only form a regular convex pattern on the waistband part 2 of the underwear after hot stamping, but more importantly, they cause the effect of uneven thickness by locally changing the fiber structure of the fabric. During the hot stamping process, the high temperature causes the fibers in the heated area of ​​the fabric to shrink and become tighter, while the unheated area remains unchanged. This difference leads to the unevenness of the fabric surface, and then forms a stable three-dimensional bulging structure after cooling. That is, by partially changing the physical properties of the fabric and utilizing the difference in temperature and pressure, a thick and thin structure is created on the fabric. This structure visually presents a three-dimensional bulging effect, thereby achieving a three-dimensional bulging of the waistband area 2 without any seams; the raised pattern refers to the pattern formed by the hot stamping points. Since the fabric thickness of the waistband area 2 of the underwear is relatively thin, in fact, multiple relatively microscopic structural changes form an overall relatively large bulging effect structure that does not require sewing.

[0032] The arrangement of the dotted adhesive layer 5 and the three-dimensional bulging structure 4 together realizes the seamless connection and three-dimensional shaping of the underpants waistband 2, thereby improving the comfort and aesthetics of the underpants. The underpants body 3 and the underpants waistband 2 are both made of soft and breathable fabrics to ensure comfort and hygiene.

[0033] Embodiment 1:

[0034] This embodiment provides a pair of men's underwear with a seamless crotch structure. The design of the underwear is intended to solve the problems existing in the traditional underwear manufacturing process and to improve wearing comfort, hygiene and durability.

[0035] Specifically, the men's underwear includes a men's underwear body 1, which includes a waistband portion 2 and a body portion 3. The waistband portion 2 and the body portion 3 are connected by a plurality of dot-shaped adhesive layers 5. The dot-shaped adhesive layers 5 are located in the overlapping area of ​​the waistband portion 2 and the body portion 3, and are evenly distributed along the edge of the waistband portion 2, thereby forming a seamless connection structure. This design not only eliminates the discomfort that may be caused by the sewing line, but also improves the aesthetics of the underwear.

[0036] The dot-shaped glue layer 5 is formed by glue with high viscosity and quick drying. This glue can be quickly solidified after being dispensed, ensuring a firm connection between the waistband portion 2 and the body portion 3. At the same time, the diameter of the dot-shaped glue layer 5 is controlled between 1 mm and 5 mm, and the spacing of the dots is between 5 mm and 20 mm. Such parameter settings ensure both the stability of the connection and the aesthetics of the underwear.

[0037] At the same time, the connection method between the waistband part 2 and the body part 3 uses "multiple dot-shaped adhesive layers 5" for connection, which has the following distinctive features compared with the traditional glue bonding method:

[0038] 1. The multiple dot-shaped glue layers 5 are realized by glue dispensing technology. Specifically, during the production process, a glue dispensing device known to ordinary technicians in the art is used to apply a small amount of special glue to the overlapping area of ​​the waistband part 2 and the body part 3 of the underwear to form dot-shaped glue layers 5. These dot-shaped glue layers 5 are evenly distributed along the edge of the waistband part 2, which not only ensures the firmness of the connection, but also avoids the use of glue over a large area, thereby reducing the direct contact area between the glue and the skin and improving the comfort of wearing.

[0039] 2. Compared with the traditional glue bonding method, the advantage of the dot-shaped glue layer 5 connection method lies in its accuracy and localization. Traditional glue bonding is often large-scale, which easily causes the glue to penetrate into the inside of the underwear and come into direct contact with the skin, causing allergies or discomfort. The dot-shaped glue layer 5 greatly reduces this risk because it only bonds at specific points, which not only ensures the stability of the connection, but also reduces discomfort.

[0040] In addition, the glue used in the dot-shaped glue layer 5 has high viscosity and quick drying properties. The high viscosity ensures that the glue can firmly bond the waistband portion 2 and the body portion 3, providing sufficient connection strength. The quick drying property means that the glue can be quickly cured after being applied, thereby improving production efficiency and ensuring that the glue will not penetrate into the inner side of the underwear due to not drying for a long time.

[0041] Specifically, highly viscous glues such as polyurethane glues and epoxy resin glues can be selected, which have strong bonding strength and durability. Quick-drying glues such as cyanoacrylate glues will polymerize and solidify quickly after contacting moisture in the air, so they are suitable for fast bonding of the dot-shaped glue layer 5.

[0042] In addition, the waistband 2 also has a three-dimensional bulging structure 4 formed by a machine hot stamping process. The three-dimensional bulging structure 4 is located in the central area of ​​the waistband 2, and a regular bulging pattern is formed on the waistband 2 of the underwear through multiple hot stamping points, thereby achieving a three-dimensional effect of the waistband 2. This design not only makes the waistband 2 more beautiful, but also improves the wearing comfort. Moreover, this three-dimensional bulging structure 4 is formed by high temperature and pressure, without sewing threads, further improving the durability and hygiene of the underwear.

[0043] Specifically, the diameter of each hot stamping point is controlled between 2 mm and 10 mm, and the spacing between the hot stamping points is between 5 mm and 30 mm. Such parameter settings make the three-dimensional bulging structure 4 both aesthetically pleasing and practical.

[0044] In general, by combining the dot-shaped adhesive layer 5 and the three-dimensional bulging structure 4, the present embodiment successfully achieves seamless connection and three-dimensional shaping of the underpants waistband 2, thereby greatly improving the comfort and aesthetics of the underpants. At the same time, the underpants body 3 and the underpants waistband 2 are both made of soft and breathable fabrics to ensure comfort and hygiene.

Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
