DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(8) A preferred embodiment of a manufacturing method of a film three-dimensional mesh fabric 10 in the present invention, as shown in FIGS. 1 and 2, is orderly provided with a discharge unit 20, a hot-press unit 30, a cooling unit 40 and a collecting unit 50 arranged in a conveying direction, and includes the following steps:

(9) A first step is to have a base cloth discharge wheel 21 discharging a base cloth 11 and have a mesh fabric discharge wheel 22 discharging a mesh fabric 12 and then employ a first auxiliary roller set 23 to have the mesh fabric 12 tightly attached to the base cloth 11 with a temperature of 20 C. to 60 C. Afterward, have a film discharge wheel 24 discharging a hot-melt film 13 and employ a second auxiliary roller set 25 to have the holt-melt film 13 tightly stuck to the mesh fabric 12 at one side opposite to the base cloth 11 with a temperature of 60 t to 180 C., thus completing a first semi-finished product 101. The base cloth 11 can adopt T/C cloth (tetoron/cotton cloth), tetoron, nelon, synthetic fiber, acrylic fiber, cotton, linen, silk, elastic fiber or non-woven fabric. The mesh fabric 12 is made by having a plurality of weaving threads 121 woven together, having a plurality of grids formed among the weaving threads 121, and the mesh fabric 12 can adopt tetoron, nelon, synthetic fiber, acrylic fiber, cotton, linen, silk, elastic fiber or non-woven fabric. The hot-melt film 13 can adopt polyurethane, thermoplastic polyurethane, metal film, biaxial stretching polypropylene film, low density polyethylene film, nelon film, casting polypropylene film, polyvinyl chloride, polyethylene, polystyrene, polyester film, polypropylene, or nelon film.

(10) A second step is to have the semi-finished product 101 blown with hot air by a hot air blower with a temperature of 40 C. to 200 C. for preheating and softening the hot-melt film 13 to attain effect of preliminary shaping and positioning and then carries out heating and pressurizing with a temperature of 60 C. to 180 C. A hot-press roller set 32 can be employed to carry out heating and pressurizing by having an upper roller and a lower roller rolled and pressed oppositely to carry out thermo-compression, or a hot-press forming mold 33 can be employed to carry out heating and pressurizing by having an upper mold and a lower mold pressed fit to carry out hot compression. Preferably, the hot-press roller set 32 is first employed to carry out hot compression for a first time and then has the hot-press forming mold 33 carrying out hot compression for a second time, and additionally has a vacuum pump 34 vacuumizing the hot-press forming mold 33, such that the pressure in the hot-press forming mold 33 maintains between-2 bar and 2 bar. Thus, a part of the hot-melt film 13, corresponding to the grids 122, will sags into the grids 122 and will be tightly attached to the base cloth 11 to form a sagged portion 131, such that the surface of the hot-melt film 13 forms a plurality of insert hole 132 corresponding with the shape of the grids 12 and thus completing a second semi-finished product 102.

(11) A last step is to have the second semi-finished product 102 cooling off via a cooler 41 with a temperature of 40 C. to 30 C. and then employ a cooling clamping roller set 42 to have the second semi-finished product 102 conveyed to the collecting unit 50 to have a first finished product collecting wheel 51 rolling up the mesh fabric 12 and the hot-melt film 13 and employ a second finished product collecting wheel 52 to roll up the base cloth 11. Thus, the base cloth 11 is torn off from the second semi-finished product 102 and the sagged portion 131 sagging in the grids 122 and stuck to the base cloth 11 is removed, such that the mesh fabric 12 is formed thereon with the holt-melt film 13, which is formed with the insert holes 132 corresponding to the grids 122, thus completing a finished product of a film three dimensional mesh fabric 10.

(12) Referring to FIGS. 3 and 4, the hot-press roller set 32 has its surface annularly provided with a wheel sticking soft pad 321, while the hot-press forming mold 33 has an upper side and a lower side respectively provided with a mold soft pad 331 corresponding to the first semi-finished product 101, and a silica gel soft pad 332 is sandwiched in each mold soft pad 331. By so designing, when the hot-press roller set 32 and the hot-press forming mold 33 carry out thermo-compression to the first semi-finished product 101, the wheel sticking soft pad 321 and the mold soft pad 331, which are able to be deformed elastically, can really have the portions of the hot-melt film 13, corresponding to the grids 122, compressed in the grids 122. Thus, not only the shape of the grids 122 can be completely presented, but also the locations of the hot-melt film 13, which correspond to the woven threads 121 of the mesh fabric 12, can be compressed to present the original patterns of the woven threads 121, and the above-mentioned effects will become more evident if the vacuum pump 34 can be additionally employed to carry out vacuumization.

(13) Referring to FIGS. 5 and 6, the film three-dimensional mesh fabric 10 manufactured through above-mentioned manufacturing method contains the mesh fabric 12 having its surface formed with a plurality of grids 122 and having at least one side stuck with the hot-melt film 13, which is provided with a plurality of insert holes 132 corresponding with the grids 122. By so designing, the mesh fabric 12 can be additionally provided thereon with the hot-melt film 13 and retains the original grids 122 of the mesh fabric 12 and thus, a user can carry out design in variety of colors, material and function via the hot-melt film 13 for enhancing changeability and functionality of the mesh fabric 12. For instance, the hot-melt film 13 can be designed to form metal pattern for building decoration changes of different materials, or the hot-melt film 13 can be a reflective material to render the film three-dimensional mesh fabric formed with reflective functionality.

(14) Referring to FIG. 2, one special feature of this invention is that the base cloth 11 torn off from the second semi-finished product 102 and rolled up by the second finished product collecting wheel 52 has its surface retaining the sagged portions 131 that sag into the grids 122 and tightly attached to the base cloth 11, such that the surface of the base cloth 11 is formed into three-dimensional patterns corresponding with the arrangement and shape of the grids 122 to enable the base cloth 11 to be recycled and re-used for article decoration, such as shoes, clothing or handbags. Therefore, the manufacturing method of a film three-dimensional mesh fabric of this invention is able to fully make use of all the materials and has environmental protection and economic benefits.

(15) While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
