Detailed Description
Referring to fig. 1 to 3, a laminated breathable elastic adhesive film comprises an adhesive film body, wherein the adhesive film body comprises a base film 20 and a surface film 10 attached to the base film 20, the surface film 10 is an elastic film, the elasticity of the surface film 10 is greater than that of the base film 20, the base film 20 can be broken after being stretched to a certain extent to enable the adhesive film body to generate cracks, and the adhesive film body has a breathable state with the cracks. In the invention, as the elasticity of the surface film 10 of the adhesive film main body is greater than that of the base film 20, the base film 20 can be broken after being stretched to a certain degree, and then the surface film 10 attached to the base film 20 is broken, so that the adhesive film main body can generate cracks and has a ventilation function, the surface film 10 cannot be broken and can keep elasticity, and then the elasticity of the adhesive film main body can be kept.
In the invention, the base film 20 is preferably in a grid shape, so that after the base film 20 is stretched to a certain extent, the grid edge of the base film 20 can be broken, so that the cracks can be more uniformly distributed on the adhesive film main body, and the air permeability of the adhesive film main body is ensured to be similar. In this embodiment, the base film 20 is a mesh film, the mesh number is 1-50 mesh, the mesh area is 0.1-20 mm 2, the mesh film is a mature product in the field, the purchase and use are convenient, the film body made of the mesh film with the mesh number and the mesh area can obtain balanced air permeability and elasticity, and is particularly suitable for underwear products, of course, in practical application, the mesh number and the mesh area of the mesh film can be flexibly adjusted according to the needs, when the mesh area is increased, the mesh number is reduced, the number of cracks is relatively less, so that the air permeability of the film body is reduced, but the elasticity of the film body can be increased, and when the mesh surface is reduced, the mesh number is increased, so that the air permeability is enhanced, but correspondingly, the elasticity of the film body is reduced due to the increase of the cracks on the surface film 10.
In this embodiment, the base film 20 is an inelastic film, so that cracks can be easily generated by stretching, however, in practical applications, the base film 20 may be an elastic film, and the elasticity of the film is only required to be smaller than that of the top film 10.
In this embodiment, the surface film 10 is a hot melt adhesive film and is adhered to the base film 20 by a hot melt method, so that the processing and manufacturing are convenient, and the fabric can be directly adhered by directly utilizing the hot melt adhesive property of the surface film during use, so that the processing and manufacturing of clothes are convenient, and the use is convenient, however, in practical application, the surface film 10 can also be adhered by adopting glue solution or additionally coating hot melt adhesive.
In the invention, the surface layer film 10 can be a TPU hot melt adhesive film or a modified polyester hot melt adhesive film. These materials are commonly used in the art, and have excellent elasticity and hot melt adhesion, however, other suitable materials may be used for the top film 10 in practical applications. The base film 20 can be made of HDPE hot melt adhesive film, PA hot melt adhesive film, PES hot melt adhesive film, LDPE hot melt adhesive film, and is easy to stretch and tear to generate cracks, and is not easy to damage human skin, meanwhile, the hot melt adhesive function can be realized, and the base film 20 is safe and environment-friendly, and can be made of other suitable materials in practical application.
In this embodiment, the surface layer film 10 is attached to both ends of the base film 20, so that the two layers of fabric can be bonded together, and the adhesive is suitable for processing most of the clothes such as underwear, and is convenient to use, however, in practical application, the surface layer film 10 may be attached to only one end of the base film 20 as required.
The outer terminal surface of glued membrane main part is last to be attached with protection film (not shown in the figure), and the protection film can be torn from the glued membrane main part, and glued membrane main part is thinner generally, can design glued membrane main part on the one hand, prevents that glued membrane main part from appearing the fold, on the other hand, also can play the guard action to glued membrane main part, prevents that glued membrane main part from appearing the scratch and breaking or adhering to dust debris etc. this protection film can select materials such as common release paper.
In this embodiment, the thickness of the surface film 10 is 1-6 μm, the thickness of the base film 20 is 1-10 μm, so that the bonding requirement of most fabrics can be met, the thickness of the adhesive film main body can be reduced, the structural strength is ensured, and the bonded fabrics are firmer and more attractive.
The foregoing is only a preferred embodiment of the present invention, and all technical solutions for achieving the object of the present invention by substantially the same means are within the scope of the present invention.
