DETAILED OF THE PREFERRED EMBODIMENT

A preferred embodiment of a kind of woven cloth 10 in the present invention, as shown in FIGS. 1-4, is composed of lots of yarns 11 and each yarn 11 is made from several monofilaments 111 and each monofilament 111 has its outer circumference formed with a thermoplastic polymer layer 112. In this preferred embodiment, the thermoplastic polymer layer 112 is thermoplastic polyurethan and thus, after the woven cloth 10 is hot compressed by a mold, which is preset with a pattern, the woven cloth 10 will be integrally formed with a corresponding three-dimensional pattern through compressing and hot melting of the thermoplastic polymer layer 112.


A method able to integrally form a three-dimensional pattern on the woven cloth, as shown in FIG. 5, includes the following steps:


A first step is preparation of woven cloth 10. The woven cloth 10 is the composed of lots of yarns 11 and each yarn 11 is made from several monofilaments 111 and further, each monofilament 111 has its outer circumference coated with the thermoplastic polymer layer 112, which is thermoplastic polyurethan;


A second step is preparation of a hot compression mold 20. The hot compression mold 20, as shown in FIG. 6, has heat pressing function and consists of an upper mold 21 and a lower mold 22. The upper mold 21 has its inner surface preformed with protruding three-dimensional patterns 211. In this preferred embodiment, the height of the three-dimensional pattern 211 is smaller than the thickness of the woven cloth 10;


A third step is hot compression molding. The woven cloth 10 is placed in the hot compression mold 20 to be heated and compressed; and


A fourth step is obtaining of a finished product. Referring to FIGS. 3 and 4, after hot compression molding, the woven cloth 10 will produce a depressed three-dimensional pattern 12 corresponding to the protruding three-dimensional pattern 211 of the hot compression mold 20 through heat pressing and hot melting of the thermoplastic polymer, but the three-dimensional pattern 12 does not penetrate through the woven cloth 10.


A second preferred embodiment of a method able to integrally form a three-dimensional pattern on the woven cloth in the present invention, as shown in FIGS. 7 and 8, is to have the inner surface of the hot compression mold 20 preformed with a three-dimensional pattern 211, and the height of this three-dimensional pattern 211 is greater than the thickness of the woven cloth 30. Thus, after the woven cloth 30 is hot compressed through hot compressing and hot melting of the thermoplastic polymer, the woven cloth 30 will produce a three-dimensional pattern 31 corresponding to the three-dimensional pattern 211 of the hot compression mold 20, and the three-dimensional pattern 31 penetrates through the woven cloth 30. Since the three-dimensional pattern 31 can imitate the weaving pattern of general woven cloth; therefore, the woven cloth 30 has weaving effect.


A third preferred embodiment of a method able to integrally form a three-dimensional pattern on the woven cloth in the present invention, as shown in FIG. 9, is to have the woven cloth 40 composed of two kinds of different-colored yarns and make the woven cloth 40 formed with a surface layer 41 and a bottom layer 42, the surface layer 41 positioned on the bottom layer 42. Since the surface layer 41 and the bottom layer 42 are woven with different-colored yarns; therefore, the surface and the bottom of the woven cloth 40 are formed with different colors. Thus, when the height of the three-dimensional pattern 211 preformed at the inner surface of the hot compression mold 20 is approximately equal to the thickness of the surface layer 41 of the woven cloth 40, after the woven cloth 40 is hot compressed, the surface layer 41 of the woven cloth 40 will form a three-dimensional pattern 411 penetrating through the surface layer 41 by hot compressing of the thermoplastic polymer. Thus, the color of the bottom layer 42 of the woven cloth 40 can be exposed to the surface layer 41 via the three-dimensional pattern 411, letting the three-dimensional pattern 411 produce bicolor effect.


A fourth preferred embodiment of a method able to integrally form a three-dimensional pattern on the woven cloth in the present invention, as shown in FIGS. 10 and 11, is to prepare two pieces of woven cloth 50, 60 in the first step and then, have the woven cloth 50, 60 overlapped on each other and placed in the hot compression mold 20 to carry out heating and compressing. After the woven cloth 50 is hot compressed through hot compressing and hot melting of the thermoplastic polymer, the upper woven cloth 50 will form a depressed three-dimensional pattern 51 corresponding to the hot compression mold 20 and simultaneously, the upper woven cloth 50 and the lower woven cloth 60 will be fused and fixed together due to compressing and hot melting of the location of the depressed three-dimensional pattern 51.


What is worth mentioning is that after the woven cloth 10 of this invention is hot compressed, the woven cloth 10 will be hardened because of hot melting of the thermoplastic polymer, able to enhance hardness of the woven cloth 10. Therefore, the woven cloth 10 can present different hardness through hot pressing of the hot compression mold 20.



FIG. 12 shows that this invention can be applied to the vamp 70 of a shoe. The vamp 70 is made by using the finished product of various kinds of woven cloth formed with different three-dimensional patterns of this invention. The vamp 70 can form various effects according to the needs of different parts. For instance, to be used for the front section of the vamp 70, which needs to increase hardness, double-layer woven cloth is hot compressed in the hot compression mold 20 to be combined to form a reinforced part 71, and to be used for the middle section of the vamp 70, the woven cloth is hot compressed by the hot compression mold 20 to form a first three-dimensional pattern 72 penetrating through the woven cloth, and for the rear section of the vamp 70, the double-layer woven cloth is hot compressed by the hot compression mold 20 to form a depressed second three-dimensional pattern 73 and make the double-layer woven cloth combined and fixed together. Therefore, the same woven cloth of this invention can be formed thereon with various effects through hot compressing once by the hot compression mold 20 in accordance with needs, or integrally formed with height different patterns or integrally formed with penetrating patterns and further formed with various kinds of hardness. Obviously, the invention can be applied extensively and can attain many different effects.


The special feature of this invention is that the woven cloth of this invention can be integrally formed with a three-dimensional pattern through hot compressing of a hot compression mold, needless to use the method of machine sewing or sticking. Therefore, this invention not only can save time and labor and lower manufacturing cost, but also can cope with the coming of industry 4.0 without need of manpower to be a participant of full automation.
