detailed description

The application will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand and implement the application, but the examples cited are not intended to limit the application.

First, as shown in FIG. 1 to FIG. 3, in a preferred embodiment of the present application, a composite material manufacturing method 100 capable of dyeing and bonding at the same time, the first step 110 of which is to prepare an elastic material 1 and a woven sheet 2. The elastic material 1 has a paste-like latex with appropriate viscosity. Of course, the present application is not limited to latex, and can also be other elastic materials. Colors are added to the raw materials to show a predetermined color. The woven sheet 2 is a sheet-like cloth woven or woven by fiber threads (such as nylon threads, cotton threads, or plastic threads, etc.), and has a first surface 22, a second surface 24 and communicating with the first and second surfaces 22 24. The woven sheet 2 is pre-rolled for use in subsequent processes.

The second step 120 of the present application: coating the elastic material 1 on the first surface 22 of the woven sheet 2. In detail, one end of the braided sheet 2 is continuously extended and moved toward the other end through a conveyor belt (not shown in the figure), and the braided sheet 2 is fed into the conveyor belt, and an elongated scraper 3 is provided above one end of the conveyor belt. (The extension direction is perpendicular to the moving direction of the conveyor belt), the scraper 3 is separated from the braided sheet 2 by a predetermined distance. Following the movement of the braided sheet 2, the scraper 3 can be used to continuously coat the elastic material 1 on the first surface 22 of the braided sheet 2. The distance between the scraper 3 and the braided sheet 2 generally constitutes the coating thickness of the elastic material 1.

The third step 130 of the present application: through a control means, the elastic material 1 penetrates into the pores 26 from the first surface 22, so that the elastic material 1 is attached to the woven sheet 2, and the elastic material 1 is placed on the second surface 24 forms a dyeing area 28. The control method uses an existing roller 4 to roll the elastic material 1 and the braided sheet 2, which can make the elastic material 1 penetrate into the pores 26 from the first surface 22 (or even penetrate the second surface 24 appropriately) by pressure. When the elastic material 1 is attached to the woven sheet 2, the elastic material 1 in each of the pores 26 can also be used to present a colored dyed area 28 on the second surface 24.

The fourth step 140 of the present application: heat forming the aforementioned bonded elastic material 1 and braided sheet 2 into a composite material 30. The foregoing heating method uses the existing oven 5, and chooses to use an oven or other heating device (such as a vulcanized foaming box), depending on the requirements of the product characteristics.

Finally, by cooling at room temperature, a finished composite material 30 with a dyed braid layer on one side and an elastic layer (latex matured) on the other side is obtained.

Therefore, the composite material manufacturing method 100 capable of dyeing and bonding at the same time of the present application utilizes the control means (the aforementioned embodiment uses rollers to press the elastic material 1 and the braided sheet 2) to make the elastic material 1 penetrate into the braid After the pores 26 of the sheet 2 are heated and formed, the dyeing of the composite material 30 (the elastic material 1 infiltrated into the pores 26 makes the dyed area 28 present a predetermined color) and the bonding of the elastic material 1 and the woven sheet 2 can be completed at one time. There is no need to dye the fabric with ink before making the existing elastic composite material and then use the adhesive to bond the fabric and the elastic layer. Therefore, there will be no water caused by the existing elastic composite material using solvents, cleaning agents and adhesives. Pollution, waste water and air pollution are not only environmentally friendly, but also faster in production methods.

In particular, the elastic material 1 penetrates into the pores 26 of the braided sheet 2 to shape the original hand, touch, and even physical and chemical properties of the braided sheet 2, and the braided sheet 2 of different materials is used to make the composite material 30. , It will also make the dyeing area 28 show different dyeing effects. Even if the composite material 30 is made of the woven sheet 2 composed of the same material of woven wire but with different weaving methods, twists or tightness, the dyeing area 28 will also be made. Different dyeing effects are produced, and variable dyeing effects are produced due to different materials (woven sheet 2), so that the composite material 30 prepared in the present application can have a variety of changes.

Secondly, the control means in the third step 130 of the present application is not limited to the pressure exerted by the aforementioned roller 4. As shown in FIG. 4, gas pressure can also be applied to the surface of the elastic material 1 so that the elastic material 1 is The pressure penetrates into the pores 26 of the braided sheet 2, and the value of the air pressure can be adjusted according to the actual state of the elastic material 1 infiltrating the pores 26.

In addition, the control means of the present application can also be heating. As shown in FIG. 5, the method of heating the elastic material 1 or the woven sheet 2 is used to change the flow state of the elastic material 1 or the size of the pores 26 of the woven sheet 2 to make the The elastic material 1 can naturally penetrate into the pores 26. In detail, the elastic material 1 has better fluidity after heating, and is also easy to penetrate into the pores 26. After the woven sheet 2 is heated, the pores 26 can be slightly expanded, which can also make the elastic material 1 more easily penetrate into the pores 26 ( Different braided wires have different thermal expansion numbers, so the heating temperature of the braided sheet 2 can be adjusted according to the choice of material). Moreover, the heating control means can also heat different parts of the braided sheet 2 at different temperatures at the same time, so that the pores 26 of different parts of the braided sheet 2 have different expansion degrees. As a result, the elastic material 1 penetrates into the pores. The state of 26 will be inconsistent, and the dyeing area 28 may change the dyeing effect (for example, the change of the color depth or the change of the gradual visual effect).

Furthermore, in the step of applying the elastic material 1 to the surface of the woven sheet 2 using the scraper 3 in the present application, several elastic materials 1 with different colors can also be input in parallel between the scraper 3 and the woven sheet 2, as shown in FIG. 6 As shown, the squeegee 3 is used to simultaneously coat several elastic materials 1 of different colors on the first surface 22 of the woven sheet 2 so that the dyed area 28 after forming has multiple colors.

In addition, as shown in Fig. 7, this application can also input several different colors of elastic material 1 between the scraper 3 and the woven sheet 2 in an overlapping manner, so that the elastic material 1 of different colors can be mixed by the scraper 3 and applied to it. The surface of the woven sheet 2 is further made the dyeing area 28 have the effect of color mixing and camouflage.

Based on this, the present application can not only use the change of the control means to change the visual effect of the dyed area 28 of the woven sheet 2, but also adjust the input mode of the elastic material 1 to change the color of the dyed area 28. .

Moreover, as shown in FIG. 8, after the elastic material 1 penetrates into the pores 26 from the first surface 22 by the pressure of the roller 4, several water droplets 6 (or hydrophilic Material, hydrophobic material, etc., or quickly mix a predetermined ratio of hydrophilic material and hydrophobic material in the water source that outputs the water droplets 6, so that the water droplets 6 can be affected by the hydrophobic material and present a pseudo-dispersed state), the method is as follows: The roller 4 is additionally provided with a water delivery pipe 41, and several water delivery ports 42 are arranged on the surface, so that when the roller 4 is pressed on the elastic material 1, an appropriate amount of water can be output from the water delivery openings 42 to the surface of the elastic material 1. Of course, this application is A number of water droplets 6 (or hydrophilic material, hydrophobic material, or a predetermined ratio of hydrophilic material and hydrophobic material are quickly mixed in the water source that outputs the water droplets 6 on the surface of the elastic material 1 so that the water droplets 6 can appear false). The method of the dispersed state) is not limited to the foregoing, and may be directly spraying water on the surface of the elastic material 1, or locally or dispersedly arranged on the surface of the elastic material 1 in a printing-like manner.

Accordingly, during the heating and forming process of the elastic material 1 and the braided sheet 2, each of the water droplets 6 can be heated to evaporate, and a bubble structure is generated in the elastic material 1 (the use of hydrophilic or hydrophobic materials can produce hydrophilic or The hydrophobic structure obtains the characteristics of water affinity or repelling water) or the dyeing area 28 has a camouflage effect. The aforementioned hydrophilic materials refer to materials that have the characteristics of being close to and attracting moisture, such as activated carbon, etc., while hydrophobic materials refer to materials that have the characteristics of repelling moisture, such as non-hydrophilic materials such as glass particles or metal particles, both of which are Existing, the detailed materials will not be repeated here, and this application will choose according to the needs.
