Description

Technical Field

[0001] This utility model relates to the field of underwear technology, and in particular to an underwear side-clamp breathable interlayer structure and underwear having the same structure. Background Technology

[0002] As everyday clothing that fits closely to the human body, the side gussets of underwear are key functional areas that connect the main body of the underwear to the shoulder straps and cover the underarms and the outer side of the chest. The structural design of this part directly affects the wearing experience and functional practicality.

[0003] Currently, the mainstream design for the side-clip structure of underwear in the industry is "two layers of fabric + full / dot adhesive bonding + straight hole perforation". This involves bonding the inner and outer fabrics together using a full-coverage adhesive layer or discrete dot adhesive layers to form the sandwich structure, and then using mechanical punching or laser perforation to create through-holes of equal diameter in the sandwich to achieve breathability. However, this design has the following significant drawbacks in practical applications, making it difficult to simultaneously meet the core requirements of the side-clip area:

[0004] Firstly, the ventilation holes in traditional designs are mostly "straight holes of equal diameter that penetrate two layers of fabric". Since the underarm area is where the human body secretes more sweat, during the wearing process, sweat, sebum and skin metabolic debris are easy to adhere to the surface of the hole wall. Over time, they will gradually block the hole, causing the ventilation cross-sectional area of ​​the ventilation hole to continuously decrease and the ventilation effect to drop significantly.

[0005] Secondly, in existing solutions, the inner and outer fabrics are bonded together using only a full-layer or dot-layer adhesive. The side-clamping area of ​​the bra requires frequent dynamic movements such as raising arms, bending over, and turning. During these movements, the inner fabric, being in direct contact with the skin, shifts with the body, while the outer fabric, connected to the main body of the bra, remains relatively fixed. This creates a tendency for relative sliding along the fabric surface. This interlayer displacement leads to misalignment of the originally precisely aligned ventilation holes in the inner and outer fabrics. In severe cases, the non-porous areas of the inner fabric may even cover the ventilation holes of the outer fabric, directly blocking airflow and rendering the ventilation holes meaningless. Furthermore, the displaced fabric may accumulate under the armpits, further exacerbating discomfort.

[0006] In summary, the existing side-clip interlayer structure design of underwear is difficult to simultaneously meet the functional requirements of preventing clogging of ventilation holes and ensuring stable positioning. There is an urgent need for a new interlayer structure that can systematically solve the above pain points and meet the core requirements of structural stability, wearing comfort and breathability. Utility Model Content

[0007] Therefore, the technical problem to be solved by this utility model is to overcome the technical defects of the existing underwear side interlayer, such as the easy misalignment and blockage of the ventilation holes, and to propose an underwear side interlayer ventilation structure and underwear with it.

[0008] To solve the above-mentioned technical problems, this utility model provides a breathable interlayer structure for underwear side clips, characterized in that it includes:

[0009] A skin-friendly layer having an outer surface and an inner surface arranged opposite each other along the thickness direction, wherein the outer surface is provided with raised ribs;

[0010] A support layer is disposed on the outer surface of the skin-friendly layer. The surface of the support layer facing the skin-friendly layer has a groove adapted to the raised rib. The groove and the raised rib are configured to fit together and be positioned to limit the relative sliding between the skin-friendly layer and the support layer.

[0011] An adhesive layer is sandwiched between the skin-friendly layer and the support layer. The adhesive layer is a hot melt adhesive layer with ring-shaped dots distributed in order to bond the skin-friendly layer and the support layer to form a sandwich structure.

[0012] The variable diameter vent holes penetrate the skin-friendly layer, the adhesive layer, and the support layer to form a breathable channel that runs through both ends. The diameter of the variable diameter vent holes gradually decreases from the skin-friendly layer to the support layer.

[0013] In one embodiment of this utility model, the raised ribs are integrally woven with the skin-friendly layer.

[0014] In one embodiment of this utility model, the raised ribs are distributed in a ring on the outer surface of the skin-friendly layer, and the height of the raised ribs is 0.1-0.15mm.

[0015] In one embodiment of the present invention, the variable diameter vent hole passes sequentially through the central area surrounded by the protruding rib and the groove, and the hole wall of the variable diameter vent hole does not contact the side wall of the protruding rib and the groove.

[0016] In one embodiment of this utility model, the diameter of the variable-diameter breathable pore is 1.5-2 mm on the skin-friendly layer side and 0.8-1 mm on the support layer side.

[0017] In one embodiment of this utility model, the groove on the support layer is formed by laser engraving.

[0018] In addition, this utility model also provides an underwear, which includes a breathable interlayer structure with side clasps as described above.

[0019] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0020] During the pressing process, the raised ribs of the skin-friendly layer and the grooves of the support layer are interlocked and positioned, and the dotted adhesive layer forms a double positioning, which can effectively limit the relative sliding of the two layers of fabric, thereby reducing the problem of reduced breathability of the side layer of the underwear due to misalignment of the ventilation holes; moreover, the ventilation holes adopt a variable diameter design of "larger inside and smaller outside", which can improve the sweat excretion efficiency and reduce the adhesion of the hole wall; the smaller diameter of the variable diameter ventilation holes on the support layer side can ensure that the ventilation channel is unobstructed for a long time, and the ventilation and anti-clogging effect is excellent.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figures 1 to 3 As shown, this utility model embodiment provides a breathable interlayer structure for underwear side clasps, including a skin-friendly layer 1, a support layer 3, an adhesive layer 2, and variable-diameter ventilation holes 4. The skin-friendly layer 1 has an outer surface and an inner surface that are arranged opposite each other along the thickness direction, and the outer surface is provided with raised ribs 11. The support layer 3 is disposed on the outer surface of the skin-friendly layer 1, and the surface of the support layer 3 facing the skin-friendly layer 1 is provided with grooves 31 that are adapted to the raised ribs 11. The grooves 31 and the raised ribs 11 are configured to fit and position each other to limit the relative sliding between the skin-friendly layer 1 and the support layer 3. The adhesive layer 2 is sandwiched between the skin-friendly layer 1 and the support layer 3. The adhesive layer 2 is a hot melt adhesive layer 2 with annular dots distributed in a dotted pattern. The adhesive layer 2 bonds the skin-friendly layer 1 and the support layer 3 to form an integral interlayer. The variable-diameter ventilation holes 4 penetrate the skin-friendly layer 1, the adhesive layer 2, and the support layer 3 to form a breathable channel that is open at both ends. The diameter of the variable-diameter ventilation holes 4 gradually decreases along the direction from the skin-friendly layer 1 to the support layer 3.

[0028] During the pressing process, the raised ribs 11 of the skin-friendly layer 1 and the grooves 31 of the support layer 3 are fitted and positioned, and the dotted adhesive layer 2 is used to bond them together to form a double positioning, which can effectively limit the relative sliding of the two layers of fabric, thereby reducing the problem of reduced breathability of the side layer of the underwear due to misalignment of the ventilation holes; moreover, the walls of the variable diameter ventilation holes 4 are provided with guide grooves, which can improve the sweat excretion efficiency and reduce the adhesion of the hole walls; the diameter of the variable diameter ventilation holes 4 on the support layer 3 side is smaller, which can ensure that the ventilation channel is unobstructed for a long time and has a good breathability and anti-clogging effect.

[0029] The aforementioned raised ribs 11 are integrally woven with the skin-friendly layer 1, and the grooves 31 on the support layer 3 are formed by laser engraving. The raised ribs 11 are distributed in a ring on the outer surface of the skin-friendly layer 1, and the height of the raised ribs 11 is 0.1-0.15mm. Preferably, the height of the raised ribs 11 is 0.1mm. The height of the raised ribs 11 of 0.1mm can form an "effective mechanical interlock". When the skin-friendly layer 1 and the support layer 3 slide relative to each other, the sidewall of the raised ribs 11 will generate "frictional resistance" with the sidewall of the grooves 31. Combined with the adhesive effect of the adhesive layer 2, the interlayer displacement can be controlled within 0.1mm, meeting the functional requirement of "no misalignment of the vent holes".

[0030] It should be emphasized that the variable diameter vent 4 does not "randomly penetrate the interlayer", but penetrates along a fixed path of "skin-friendly layer 1 → raised rib 11 → adhesive layer 2 → groove 31 → support layer 3". The variable diameter vent 4 passes through the central area enclosed by the raised rib 11 and the groove 31 in sequence, and the hole wall of the variable diameter vent 4 does not contact the side wall of the raised rib 11 and the groove 31, ensuring that the positioning function is not damaged and the channel is not blocked. Specifically, starting from the beginning, the raised ribs 11 on the skin-friendly layer 1 are "annular raised structures surrounding the variable-diameter vent holes 4" (similar to "small circular raised rings"). The "central area" refers to the circular space enclosed by the annular raised ribs 11 (i.e., the "hole" of the ring). The variable-diameter vent holes 4 first penetrate the surface of the skin-friendly layer 1, then pass precisely through the "central area of ​​the annular raised ribs 11" (without contacting the sidewalls of the raised ribs 11, only passing through the central blank space), avoiding damage to the structural integrity of the raised ribs 11 (the raised ribs 11 need to be retained to fit into the grooves 31). After passing through the annular raised ribs 11, the variable-diameter vent holes 4 continue to penetrate the intermediate adhesive layer 2; subsequently, the variable-diameter vent holes 4 are precisely aligned with the "central area of ​​the annular groove 31" on the support layer 3 (concentric with the central area of ​​the raised ribs 11), penetrating the central blank space of the annular groove 31 (again, without contacting the sidewalls of the groove 31). After the variable diameter vent 4 passes through the central area of ​​the annular groove 31, the variable diameter vent 4 eventually penetrates the support layer 3, forming a complete channel that "penetrates the entire interlayer from the inside to the outside".

[0031] Furthermore, the diameter of the aforementioned variable-diameter vent 4 on the skin-friendly layer 1 side is 1.5-2mm, and the diameter on the support layer 3 side is 0.8-1mm. Preferably, the diameter of the variable-diameter vent 4 on the skin-friendly layer 1 side can be 1.8mm. Since the skin-friendly layer 1 directly contacts sensitive skin areas such as the armpit and outer chest, the 1.8mm diameter vent has a larger contact area with the skin, which can reduce the local pressure of the vent on the skin and reduce the problem of wearing pain and pressure marks caused by the "point pressure" of the small vent. The diameter of the variable-diameter vent 4 on the support layer 3 side can be 1mm. The 1mm diameter vent and the 1.8mm diameter vent of the skin-friendly layer 1 form a "larger inside and smaller outside" conical channel. After the airflow enters from the skin-friendly layer 1 side, the "slight pressure boosting effect" is generated due to the gradual narrowing of the vent, which can increase the airflow speed and quickly remove the stuffy and humid air from the armpit. The 1mm diameter vent can effectively block dust and other foreign objects from entering the channel, and has a good anti-clogging effect.

[0032] Corresponding to the above-described embodiment of the breathable side-clamping interlayer structure for underwear, this utility model embodiment also provides an underwear having the above-described breathable side-clamping interlayer structure for underwear, possessing all the beneficial effects of the above-described breathable side-clamping interlayer structure for underwear.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
