Hereinafter, several preferred embodiments of the present invention are listed, and further detailed descriptions are done in conjunction with the drawings as follows:

First, as shown in Figures 1 to 3, in a preferred embodiment of the present invention, a composite material manufacturing method 100 capable of simultaneous dyeing and lamination, the first step 110 is to prepare an elastic material 1 and a woven sheet 2 . The elastic material 1 is a paste latex with suitable viscosity. Of course, the present invention is not limited to latex, and can also be other elastic materials. The raw materials can be added with colorants to show a predetermined color. The woven sheet 2 is a sheet-like cloth woven or woven from fiber wires (such as nylon threads, cotton threads or plastic material wires, etc.), and has a first surface 22, a second surface 24 and the first and second surfaces. The plurality of holes 26 in 22 and 24, the braided sheet 2 is pre-rolled and used for pulling out in the subsequent process.

The second step 120 of the present invention: coating the elastic material 1 on the first surface 22 of the woven sheet 2 . In detail, one end of the woven sheet 2 is continuously extended and moved toward the other end through a conveyor belt (not shown in the figure), and a long sheet-shaped scraper is provided above one end of the woven sheet 2 into the conveyor belt. 3 (the extension direction is perpendicular to the moving direction of the conveyor belt), the scraper 3 is separated from the woven sheet 2 by a predetermined distance, and the elastic material 1 is input to the front side of the scraper 3 (towards the side of the knitted sheet 2 roll-up part) on the surface of the woven sheet 2 , so that with the moving process of the woven sheet 2, the elastic material 1 can be continuously coated on the first surface 22 of the woven sheet 2 by the scraper 3, and the distance between the scraper 3 and the woven sheet 2 generally constitutes the distance between the elastic material 1 Apply thickness.

The third step 130 of the present invention is to use a control means to make the elastic material 1 penetrate into the pores 26 from the first surface 22 , make the elastic material 1 fit the woven sheet 2 , and make the elastic material 1 in the first surface 22 . The two surfaces 24 form a dyed area 28 . The control means uses a conventional roller 4 to roll the elastic material 1 and the woven sheet 2, so that the elastic material 1 can penetrate into the pores 26 from the first surface 22 (or even properly penetrate the second surface 24) by using pressure, Not only can the elastic material 1 be attached to the woven sheet 2 , but also the elastic material 1 in each of the pores 26 can be used to present a colored dyed area 28 on the second surface 24 .

The fourth step 140 of the present invention is to heat and form the composite material 30 from the previously attached elastic material 1 and the woven sheet 2 . The aforementioned heating method utilizes the conventional oven 5, and the method of using an oven or other heating device (such as a vulcanizing foaming box) is determined according to the requirements of product characteristics.

Finally, one side is dyed by cooling at room temperature The finished product of the composite material 30 with the colored woven layer and the elastic layer (latex matured) on the other side.

Thereby, the composite material manufacturing method 100 of the present invention, which can be dyed and bonded at the same time, utilizes the control means (the aforementioned embodiment uses a roller to press on the elastic material 1 and the woven sheet 2), so that the elastic material 1 is infiltrated into the weaving. After the pores 26 of the sheet 2 are heated and formed, the dyeing of the composite material 30 (through the elastic material 1 infiltrating into the pores 26 to make the dyed area 28 show a predetermined color) and the bonding of the elastic material 1 and the woven sheet 2 can be completed at one time. It is not necessary to dye the fabric ink first, and then use an adhesive to bond the fabric and the elastic layer, as the conventional elastic composite material is produced. Therefore, water caused by the use of solvents, cleaning agents and adhesives in the conventional elastic composite material will not occur. Problems such as pollution, waste water and air pollution, not only the process is environmentally friendly, but also the production method is faster.

In particular, by infiltrating the elastic material 1 into the pores 26 of the woven sheet 2 for shaping, the original feel, touch, and even physical and chemical properties of the woven sheet 2 can be changed. The material 30 will also cause the dyeing area 28 to exhibit different dyeing effects. Even if the woven wire of the same material is used to make the composite material 30 with woven sheets 2 composed of different weaving methods, twists or degrees of tightness, the dyeing effect will also be caused. The regions 28 produce different dyeing effects, and the various dyeing effects are produced due to different materials (woven sheets 2), so that the composite material 30 prepared by the present invention can have various changes.

Secondly, the control means in the third step 130 of the present invention is not limited to the pressure exerted by the aforementioned roller 4. As shown in the fourth figure, gas pressure can also be applied to the surface of the elastic material 1 to make the elastic material 1 seepage under pressure The air pressure can be adjusted according to the actual state that the elastic material 1 penetrates into the pores 26 of the woven sheet 2 .

In addition, the control means of the present invention can also be heating. As shown in Figure 5, by heating the elastic material 1 or the woven sheet 2, the flow state of the elastic material 1 or the size of the pores 26 of the woven sheet 2 is changed, The elastic material 1 is allowed to penetrate into the pores 26 naturally. In detail, the elastic material 1 has better fluidity after heating, and is more likely to penetrate into the pores 26, and the woven sheet 2 can be slightly expanded after heating, which can also make the elastic material 1 more easily penetrated into the pores 26 ( Different braided wires have different thermal expansion coefficients, so the heating temperature of braided sheet 2 can be adjusted according to the choice of material). Moreover, the heating control means can simultaneously heat different parts of the woven sheet 2 at different temperatures, so that the degree of expansion of the pores 26 in different parts of the woven sheet 2 is different, so that the elastic material 1 penetrates into each pore The state of 26 will be inconsistent, and the dyeing area 28 can produce changes in dyeing effects (eg, changes in color shades or changes in gradation visual effects).

Furthermore, in the present invention, in the step of coating the elastic material 1 on the surface of the woven sheet 2 with the scraper 3, the elastic materials 1 with different colors can also be input in parallel between the scraper 3 and the knitted sheet 2, as in the sixth example. As shown in the figure, the scraper 3 can coat the elastic materials 1 of different colors on the first surface 22 of the woven sheet 2 at the same time, so that the dyed area 28 after molding has multiple colors.

In addition, as shown in Figure 7, the present invention can also input several elastic materials 1 of different colors between the scraper 3 and the woven sheet 2 in an overlapping manner, so that the elastic materials 1 of different colors can be mixed and applied by the scraper 3 on woven sheet 2 sheets surface, so that the dyeing area 28 has the effect of color mixing and camouflage.

Based on this, the present invention can not only utilize the change of the control means to change the visual effect of the dyeing area 28 of the woven sheet 2, but also make the color of the dyeing area 28 change by adjusting the input method of the elastic material 1. .

Moreover, as shown in Figure 8, after the elastic material 1 penetrates into the pores 26 from the first surface 22 by the pressure of the roller 4, a plurality of water droplets 6 (or hydrophilic water droplets 6) can be sprinkled on the surface of the elastic material 1. materials, hydrophobic materials, etc., or quickly mix a predetermined proportion of hydrophilic materials and hydrophobic materials in the water source of the output water droplets 6, so that the water droplets 6 can be affected by the hydrophobic materials and are in a pseudo-dispersed state), the method is described in The roller 4 is provided with additional water delivery pipes 41 and a plurality of water delivery ports 42 on the surface, so that the roller 4 can output an appropriate amount of water from each water delivery port 42 to the surface of the elastic material 1 when the roller 4 is pressed against the elastic material 1. Of course, the present invention applies to the elastic material 1. 1. The method of spraying a plurality of water droplets 6 on the surface (or hydrophilic materials, hydrophobic materials, or rapidly mixing a predetermined proportion of hydrophilic materials and hydrophobic materials in the water source of the output water droplets 6, so that the water droplets 6 can be in a state of false dispersion) Not limited to the above, water can also be directly sprayed on the surface of the elastic material 1 , or locally or dispersedly disposed on the surface of the elastic material 1 in other ways such as printing.

Accordingly, in the process of heating and forming the elastic material 1 and the woven sheet 2, each of the water droplets 6 can be heated and evaporated, and a bubble structure can be generated in the elastic material 1 (a hydrophilic or hydrophobic material can be used to generate a hydrophilic or hydrophobic structure, to obtain affinity for moisture or to repel moisture) or to impart a camouflage effect to the dyed area 28. The aforementioned hydrophilic materials refer to materials that have the properties of being close to and attracting moisture. Materials, such as activated carbon, etc., and hydrophobic materials refer to materials with moisture-repellent properties, such as non-hydrophilic materials such as glass particles or metal particles, both of which are well known, and will not be repeated here. , the present invention is selected according to the needs.

To sum up, the present invention provides a method for producing a composite material that can be dyed and pasted at the same time. By means of the control method, the elastic material is infiltrated into the pores of the woven sheet and then heated and formed. The lamination and synthesis of the sheet can solve the problems of waste water, water and air pollution caused by the use of solvents, cleaning agents and adhesives in the dyeing and laminating steps of conventional elastic composite materials. Not only is the process environmentally friendly, but also the production method is faster , the dyeing effect is more diverse and has practical value; the reason is that the present invention does meet the requirements of an invention patent, and an application is filed in accordance with the law.

The above descriptions are only some preferred embodiments of the present invention, and are not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the appended patent application.
