Description

Hot melt mesh composite structure

The novel provides a heat-fusible mesh composite structure, in particular to a layered technician of a heterogeneous hot melt adhesive web.

According to the present, the hot-melt mesh film is a hot-melt adhesive which is drawn into a mesh shape by drawing, laying and rolling. It has double-sided bonding performance and is an indispensable accessory for garment making. It is widely used in clothing and various textile fabrics. The bonding between the sponge and the non-woven fabric, or the bonding of various patterns, the production of the shoes and hats, the leather parts, etc., is easy to operate, and the hot-melt film is only placed on the two layers to be bonded. Pressing with iron or hot press for 10~20 seconds, it has high bonding strength, good gas permeability, good washing resistance, no foaming, no wrinkles, no glue, soft and elastic feeling. In addition, the hot-melt mesh film has the advantage of no pollution. As a composite material, it can also be widely used in furniture, wood, interior decoration, sound insulation materials, and automotive ceilings and interior parts.

The traditional hot-melt mesh film is generally formed by PES fiber-optic mesh molding, or PA fiber-fiber mesh molding, or EVA fiber-fiber mesh forming single-layer material, hardness, density and wear resistance between different materials. Sex, buckling resistance, heat resistance, oil resistance. . . And other physical characteristics, more or less Differences exist depending on actual usage requirements or selling prices.

However, when the single-layer hot-melt mesh film is bonded to two substrates of different physical properties such as bonded wood chips and fabrics, or when it is applied to an environment subject to extreme external stress, the comprehensive physical properties of the bonded portion cannot be satisfied. User requirements.

In view of this, the creator has developed the novelty after years of professional experience and experience in this industry.

The present invention provides a hot-melt mesh composite structure composed of a first hot-melt mesh film and a second hot-melt mesh film; wherein the first hot-melt mesh film is formed by paving a TPU-based resin fiber wire, which has a corresponding first The second hot-melt web is formed by laying a non-TPU-like resin fiber and controlling the melting point to be different from the first hot-melt film, and the second hot-melt film also has a corresponding first side and The second side; the first surface of the first and second hot-melt webs is joined to form a multi-layer composite structure by using a residual temperature of the molding.

Therefore, when the two substrates are bonded by hot pressing, the hot-melt mesh film having a lower melting point can be first infiltrated into the fiber pores of the hot-melt mesh film having a higher melting point, and the TPU resin and the non-TPU resin are used. The physical properties of the material alternately bond the two substrates, thereby integrating the physical properties of the bonded portions of the two substrates, so that they can be more widely applied to different environments.

The seventh drawing is a schematic diagram of the manufacturing process of the second embodiment of the present invention.

Referring to the first to third figures, the present invention includes at least a first hot-melt web 10 which is formed by pulling the TPU-based resin fiber filaments with the first extrusion head A1 and laying them on the conveyor belt B. The first surface 11 and the second surface 12 have a plurality of fiber apertures extending through the first surface 11 and the second surface 12, and the second surface 12 of the first thermal melting film 10 is flatly attached to the conveyor belt B. And a second hot-melt web 20, which is formed by pulling out a non-TPU-based resin fiber of PES, PA or EVA material by the second extrusion head A2, and laying it on the first hot-melt web 10 to form, and Controlling the melting point of the second hot-melt mesh film 20 is different from the first hot-melt mesh film 10, the second hot-melt mesh film 20 also has a corresponding first surface 21 and second surface 22, and has a plurality of first surface 21, The first surface 21 of the second hot-melt web 20 is affixed to the first surface 11 of the first hot-melt web 10 to make the first hot-melt web 10 and the second hot-melt web. The first faces 11, 21 of the film 20 are joined by a two-roller C1, C2 to form a two-layer composite structure by the residual temperature of the molding.

Please cooperate with the second and fourth figures. When the two substrates 30 and 40 are to be bonded by heat pressing, the melting points of the first hot-melt mesh film 10 and the second hot-melt mesh film 20 are different, if the first When the melting point of the hot-melt film 10 is lower than that of the second hot-melt film 20, the first hot-melt film 10 having a lower melting point may be infiltrated into the fiber pores 200 of the second hot-melt film 20 in the hot pressing process. The two substrates 30 and 40 are interlaced by the physical properties of the TPU resin and the non-TPU resin, and the physical properties of the bonding sites of the two substrates 30 and 40 are integrated, so that the two substrates are applied to different materials. At 30, 40, or when applied to environments subject to extreme external stress, the combined strength of the bonded part can meet the requirements of the user.

Please refer to the fifth, sixth and seventh figures, which further illustrate that the present invention can be directly used in combination with a substrate 30 which is made of artificial leather, fabric, wallpaper or other planar material, which only needs to be The substrate 30 is driven by the conveyor belt B to sequentially pass through the first extrusion head A1 and the second extrusion head A2, so that the second surface 12 of the first thermal fusion web 10 is flatly attached to the substrate 30, and then the second heat is applied. The first surface 21 of the molten mesh film 20 is flatly attached to the first surface 11 of the first hot-melt mesh film 10, and then the residual temperature formed by the first hot-melt mesh film 10 and the second hot-melt mesh film 20 is used in the two rollers C1 and C2. After pressing, it can be joined into a three-layer composite structure. For the same reason, the substrate 30 can also be replaced by a third hot-melt film, for example, when the first surface 11 of the first hot-melt film 10 is joined to the first surface 21 of the second hot-melt film 20, the first hot-melt film The second surface 12 can also be connected to a third hot-melt film. The material of the third hot-melt film can be the same as or different from the second hot-melt film 20, and only the first hot-melt film 10 and the second heat-melt are controlled. The omentum 20 and the third hot-melt web can simultaneously increase the overall bonding strength by the physical properties of two or three materials.

In summary, the new type has the advantages of comprehensive strength improvement when bonding, and the overall structure is also novel, and should meet the requirements of new patents, and apply according to law. The above description is only one of the preferred embodiments of the present invention, that is, the average variation or modification of the scope of the present invention should remain within the scope of the present invention.
