具体实施方式Detailed ways
参照图1至图3，一种贴合式透气弹力胶膜，包括胶膜主体，胶膜主体包括基膜20和贴附在基膜20上的表层膜10，表层膜10为弹性膜且表层膜10的弹性大于基膜20的弹性，基膜20拉伸至一定程度后能够破裂而使胶膜主体产生裂纹，胶膜主体具有存在裂纹的透气状态。本发明中，由于胶膜主体的表层膜10的弹性大于基膜20的弹性，拉伸至一定程度后能够使基膜20破裂进而使贴附在基膜20上的表层膜10随之破裂，从而使得胶膜主体能够产生裂纹而具备透气功能，并且表层膜10不会断裂而能够保持弹性，继而能够保留胶膜主体的弹性，实际应用中，将胶膜主体粘贴在弹性面料上之后，经过首次穿戴等而产生拉伸后即可使胶膜主体具备透气性能，并且该透气性能在后续使用中不会消失，能够有效保证服饰、箱包等的透气性，提高穿戴舒适度，加工和使用也更为方便。With reference to Fig. 1 to Fig. 3, a kind of bonding type air-permeable elastic adhesive film comprises adhesive film main body, and adhesive film main body comprises base film 20 and the surface layer film 10 that is attached on the base film 20, surface layer film 10 is elastic film and surface layer The elasticity of the film 10 is greater than that of the base film 20 , and the base film 20 can rupture after being stretched to a certain extent to cause cracks in the main body of the adhesive film. The main body of the adhesive film has a gas-permeable state with cracks. In the present invention, since the elasticity of the surface film 10 of the main body of the adhesive film is greater than that of the base film 20, the base film 20 can be broken after being stretched to a certain extent, and then the surface film 10 attached to the base film 20 can be ruptured thereupon. Thereby, the main body of the adhesive film can produce cracks and have a breathable function, and the surface film 10 will not break and can maintain elasticity, and then the elasticity of the main body of the adhesive film can be retained. In practical applications, after the main body of the adhesive film is pasted on the elastic fabric, after After being stretched by wearing for the first time, the main body of the film can have air permeability, and the air permeability will not disappear in subsequent use, which can effectively ensure the air permeability of clothing, bags, etc., improve wearing comfort, and process and use. more convenient.
本发明中，基膜20优选呈网格状，这样在将基膜20拉伸至一定程度后，基膜20的网格边缘处能够出现断裂，使得裂纹能够更均匀的分布在胶膜主体上，保证胶膜主体各处透气性能的相近。本实施例中，基膜20为网眼胶膜，其网眼目数为1～50目，其网眼面积为0.1～20mm2，网眼胶膜为本领域内的成熟产品，便于采购和使用，利用该种网眼目数和网眼面积的网眼胶膜制成的胶膜主体能够获得较为平衡的透气性能和弹力，特别适用于内衣产品使用，当然，实际应用中，网眼胶膜的网眼目数和网眼面积也可根据需要灵活调整，网眼面积增大时，网眼目数变小，裂纹的数量相对较少，从而会使胶膜主体的透气性能降低，但是能够增加胶膜主体的弹性，相应的，网眼面减小时，网眼目数增大，裂纹数量增加，从而会增强透气性能，但是相应的由于表层膜10上裂纹增加，会减小胶膜主体的弹性。In the present invention, the base film 20 is preferably in the shape of a grid, so that after the base film 20 is stretched to a certain extent, fractures can occur at the edge of the grid of the base film 20, so that cracks can be more evenly distributed on the main body of the adhesive film , to ensure that the air permeability of the main body of the film is similar. In this embodiment, the base film 20 is a mesh adhesive film with a mesh number of 1 to 50 mesh and a mesh area of 0.1 to 20 mm 2 . The mesh adhesive film is a mature product in this field, which is convenient for purchase and use. The main body of the film made of a mesh film with different mesh numbers and mesh areas can obtain a relatively balanced air permeability and elasticity, and is especially suitable for underwear products. Of course, in practical applications, the mesh number and mesh area of the mesh film It can also be adjusted flexibly according to the needs. When the mesh area increases, the number of meshes becomes smaller and the number of cracks is relatively small, which will reduce the air permeability of the main body of the film, but can increase the elasticity of the main body of the film. Correspondingly, the mesh When the surface decreases, the number of meshes increases and the number of cracks increases, which will enhance the air permeability, but correspondingly, the elasticity of the main body of the film will be reduced due to the increase of cracks on the surface film 10 .
本实施例中，基膜20为非弹性膜，便于通过拉伸来产生裂纹，当然，实际应用中，基膜20也可采用带弹性的膜，只需其弹性小于表层膜10的弹性即可。In this embodiment, the base film 20 is a non-elastic film, which is convenient to produce cracks by stretching. Of course, in practical applications, the base film 20 can also be an elastic film, as long as its elasticity is smaller than that of the surface film 10. .
本实施例中，表层膜10为热熔胶膜并通过热熔方式粘贴在基膜20上，方便加工制造，使用时也可直接利用表面膜的热熔粘贴性能直接对面料进行粘合，方便衣物的加工制造，便于使用，当然，实际应用中，表层膜10也可采用胶液或另外涂覆热熔胶来对面料进行粘合。In this embodiment, the surface film 10 is a hot-melt adhesive film and is pasted on the base film 20 by hot-melting, which is convenient for processing and manufacturing. When in use, the hot-melt adhesive performance of the surface film can also be directly used to directly bond the fabric, which is convenient. The processing and manufacturing of clothes is easy to use. Of course, in practical applications, the surface film 10 can also be glued or coated with hot melt adhesive to bond the fabric.
本发明中，表层膜10可选用TPU热熔胶膜或改性聚酯热熔胶膜。，这些都是本领域内的常用材质，具有优良的弹性和热熔粘贴性能，当然，实际应用中，表层膜10也可选用其他适宜的材质制作。基膜20可选用HDPE热熔胶膜或PA热熔胶膜或PES热熔胶膜或LDPE热熔胶膜，较易拉伸撕裂而产生裂纹，并且不易对人体皮肤造成危害，同时也能够实现热熔粘合功能，安全环保，实际应用中，基膜20同样可选用其他适宜材料制作。In the present invention, the surface film 10 can be a TPU hot-melt adhesive film or a modified polyester hot-melt adhesive film. , these are commonly used materials in this field, and have excellent elasticity and hot-melt adhesive properties. Of course, in practical applications, the surface film 10 can also be made of other suitable materials. The base film 20 can be selected from HDPE hot-melt adhesive film or PA hot-melt adhesive film or PES hot-melt adhesive film or LDPE hot-melt adhesive film. Realize the hot-melt adhesive function, safety and environmental protection, in practical application, the base film 20 can also be made of other suitable materials.
本实施例中，基膜20的两端均贴附有表层膜10，能够将两层面料粘合在一起，适用于大部分内衣等衣物的加工，方便使用，当然，实际应用中，也可根据需要而仅在基膜20的一端贴附表层膜10。In this embodiment, both ends of the base film 20 are attached with a surface film 10, which can bond two layers of fabrics together, and is suitable for the processing of most underwear and other clothes, which is convenient to use. Of course, in practical applications, it can also be The surface film 10 is attached only to one end of the base film 20 as needed.
胶膜主体的外端面上贴附有保护膜(图中未示出)，保护膜可从胶膜主体上撕离，胶膜主体通常较薄，一方面能够对胶膜主体进行定型，防止胶膜主体出现皱折，另一方面，也能够对胶膜主体起到保护作用，防止胶膜主体出现刮伤破裂或粘附灰尘杂物等，该保护膜可选用常用的离型纸等材质。The outer end surface of the main body of the film is attached with a protective film (not shown in the figure). The protective film can be torn off from the main body of the film. The main body of the film is usually thin. On the one hand, the main body of the film can be shaped to prevent glue The main body of the film is wrinkled. On the other hand, it can also protect the main body of the film to prevent the main body of the film from being scratched and broken or from adhering to dust and debris. The protective film can be made of commonly used release paper and other materials.
本实施例中，表层膜10的厚度为1～6μm，基膜20的厚度为1～10μm，已能够满足大部分面料的粘合需求，并能够减小胶膜主体的厚度，保证结构强度，使得粘合后的面料更为牢固美观。In this embodiment, the thickness of the surface film 10 is 1-6 μm, and the thickness of the base film 20 is 1-10 μm, which can meet the bonding requirements of most fabrics, and can reduce the thickness of the main body of the film to ensure the structural strength. Makes the bonded fabric more firm and beautiful.
以上所述仅为本发明的优先实施方式，只要以基本相同手段实现本发明目的的技术方案都属于本发明的保护范围之内。The above descriptions are only the preferred implementation modes of the present invention, as long as the technical solutions to achieve the purpose of the present invention by basically the same means fall within the scope of protection of the present invention.
