DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be apparently and completely described in conjunction with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts fall within the protection scope of the utility model.

[0021] Please refer to Figures 1-4 The utility model provides a technical scheme: a seamless underpants pur point gluing attachment, comprising:

[0022] Underpants front material 1, the underpants front material 1 surface is uniformly provided with the hot-pressing forming concave-convex pattern A 2, and the concave-convex pattern A 2 is the corrugated structure shape integrally formed printing on the surface of underpants front material 1, and plays the role of decorating the outer surface of underpants, the underpants front material 1 bottom end middle part is equipped with the crotch fabric A 3 of arc-shaped edge structure, realizes the stamping point gluing adhesion of the bottom of front and rear underpants fabric integrative composition seamless underpants, the underpants front material 1 surface center position is equipped with the storage fabric part 10 of oval structure, and the storage fabric part 10 is the outer convex circular arc structure, so that the user is more comfortable to wear;

[0023] The back fabric 4 of the briefs is uniformly provided with a heat-pressed concave-convex pattern B5 on the surface, and the concave-convex pattern B5 is integrally formed in a corrugated structure shape and printed on the surface of the back fabric 4 of the briefs, and plays a decorative role on the outer surface of the briefs, and the concave-convex pattern B5 and the concave-convex pattern A2 need to be overlapped and seamlessly glued and bonded, one side of which is provided with a PUR point gluing and bonding part 6, which ensures that the briefs do not show obvious joint marks when worn, avoids marks and discomfort, and is especially suitable for use when wearing tight clothes, so that the joint of the briefs is smooth and mark-free, avoiding these friction points, and the design of the PUR glue point allows the briefs to have a certain elasticity in different areas, so that the briefs can better change with the body movement during wearing. Compared with traditional stitched joints, the point gluing joint is generally softer and more elastic, and the PUR point gluing and bonding process is a process of seamlessly connecting two different materials by using the adhesion of polyurethane hot melt adhesive. In this process, the polyurethane adhesive is point-coated or sprayed on the joint of the fabric in a hot melt state (usually heated to 160-180°C), and after the glue cools down, a strong adhesive joint is formed. The bottom center of the back fabric 4 of the briefs is provided with a crotch fabric B7 which is arc-shaped and overlaps the crotch fabric A3 and is point glued and bonded, so that all the stitched parts of the briefs are connected integrally by point gluing and hot pressing, achieving the effect of seamless briefs.

[0024] The concave-convex pattern A2 and the concave-convex pattern B5 are heat-pressed and bonded by the PUR point gluing and bonding part 6 to form the briefs main body 8, so that the point gluing surface of the briefs fabric bonding part is softer and more elastic, and easily adheres to the skin, and is not easy to rub against the legs. The inner side of the upper end of the briefs main body 8 is heat-pressed and bonded with an elastic band 9, which realizes tightening and binding at the position where the hip bone is not required during wearing by the user, and the outer part of the elastic band 9 is wrapped with a briefs fabric layer, so that the elastic band 9 is more comfortable when adhered to the skin, and no marks appear on the skin to cause discomfort. The crotch fabric A3 and the crotch fabric B7 are bonded together by high-temperature hot forming, and the crotch fabric A3 and the crotch fabric B7 are seamlessly bonded to form the crotch of the briefs. The inner side of the storage fabric part 10 is adhered to the back membrane patch layer 11, and the edges and corners of the storage fabric part 10 are high-temperature hot-pressed on the front opening edge end of the front fabric 1 of the briefs to form an outwardly convex storage cavity. The concave-convex surface of the concave-convex pattern A2 and the concave-convex pattern B5 is arc-shaped.

[0025] Specifically, in use, first, the fabric for making the underpants is cut into the front underpants fabric 1 and the back underpants fabric 4, while the front underpants fabric 1 and the back underpants fabric 4 are cut into the crotch fabric A and the crotch fabric B, then the PUR point adhesive bonding parts 6 at both ends of the front underpants fabric 1 and the back underpants fabric 4 are overlapped with each other, the adhesive overlapping position is placed in the shaping mold, and high-temperature stamping is used for forming, at the same time, the crotch fabric A 3 and the crotch fabric B 7 are overlapped and high-temperature stamping is used for bonding them together, and the concave-convex patterns A 2 and B 5 are longitudinally combined in the high-temperature stamping, so that the underpants fabric combination position forms a limiting pulling structure, the underpants point adhesive bonding position is not easy to appear the phenomenon of adhesive opening and breaking in pulling, the underpants are more fitted to the leg when worn, and the firmness and stability of the fitting position are further improved with the change of the leg movement.

[0026] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can be modified to the technical solutions recorded in the foregoing embodiments, or equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
