Background

The existing film-shaped material with the mesh cloth needs to attach a layer of mesh cloth to a layer of base cloth, and the processing procedure is relatively complicated. Further, since the film-like material has a double-layered fabric structure, it has problems of a large thickness and a heavy weight. Thus, for certain end-use products (e.g., functional apparel) that require a simple manufacturing process, a thin thickness, and a low weight, the film-like materials described above are clearly not able to meet the requirements of such end-use products.

Therefore, the present inventors considered that the above-mentioned defects can be improved, and made intensive studies and application of scientific principles, and finally proposed a creation for effectively improving the above-mentioned defects with reasonable design.

[ first embodiment ]

Fig. 1 to 3 show a first embodiment of the present invention. It should be noted that the related numbers and shapes mentioned in the embodiment corresponding to the drawings are only used for describing the embodiments of the present invention in detail, so as to facilitate the understanding of the contents of the present invention, and are not used to limit the scope of the present invention.

The present embodiment discloses a film-like material 100. The film material 100 includes a polymer resin film 1 and a tactile structure module 2 disposed on the polymer resin film 1. The specific configuration of each member of the film-like material 100 of the present embodiment will be described below, and then the connection relationship of each member of the film-like material 100 will be described in due course.

The polymer resin film 1 has two surfaces on opposite sides, and one surface 11 of the polymer resin film 1 is colored with a color to form a grid-like visual pattern 12.

Wherein the polymer resin film 1 is in a film shape and has a thickness of 10 to 30 μm, but the present invention is not limited thereto.

Further, the polymer resin film 1 may be, for example, at least one of a Polyurethane (PU) resin film, a Thermoplastic Polyurethane (TPU) resin film, a Polytetrafluoroethylene (PTFE) resin film, a Polyethylene (PE) resin film, a polypropylene (PP) resin film, a polyethylene terephthalate (PET) resin film, and a polymer composite film. Wherein the polymer composite film is a film-shaped substrate compounded with more than two polymer materials. In the present embodiment, the polymer resin film 1 is preferably a Polyurethane (PU) resin film, a Thermoplastic Polyurethane (TPU) resin film, or a polyethylene terephthalate (PET), but the present invention is not limited thereto.

Further, the grid-shaped visual pattern 12 is a planar printed pattern with a grid pattern, which can be used to generate the visual effect of disposing another layer of mesh cloth on the polymer resin film 1. In other words, the polymer resin film 1 can exhibit the visual effect of the double-layered cloth through the grid-shaped visual pattern 12, but the polymer resin film 1 actually has a structure of only a single-layered cloth.

More specifically, the surface 11 of the polymer resin film 1 (as shown in fig. 3, the upper surface 11 of the polymer resin film 1) is substantially a flat surface, and the grid-shaped visual pattern 12 is formed by regularly arranging a plurality of ink dots on the surface 11 of the polymer resin film 1, wherein the plurality of ink dots are substantially coplanar with the surface 11 of the polymer resin film 1.

In other words, since the thickness of the ink forming the grid-like visual pattern 12 is relatively thin (e.g., not more than 20 μm), there is no significant difference in height between the grid-like visual pattern 12 and the surface 11 of the polymer resin film 1. Accordingly, the grid-shaped visual pattern 12 formed by the plurality of ink dots can only provide a visual effect of providing another layer of mesh cloth on the polymer resin film 1, but cannot provide a tactile effect and a touch feeling of the mesh cloth.

It should be noted that in the grid-shaped visual pattern 12, the material of the plurality of ink dots is water-based polymer ink.

The composition of the aqueous polymer ink may, for example, comprise, homogeneously mixed with each other: water-based high molecular resin, an emulsifier, organic or inorganic pigment, a solvent and related auxiliary agents. The aqueous polymer resin may be, for example, an aqueous polyurethane resin, an aqueous polyester resin, an aqueous acrylic resin, or an aqueous alkyd resin …. The solvent mainly contains water and ethanol.

In this embodiment, the aqueous polymer resin is preferably at least one of an aqueous urethane resin and an aqueous acrylic resin. That is, the aqueous polymer ink is preferably at least one of an aqueous polyurethane ink and an aqueous acrylic ink, but the present invention is not limited thereto.

It should be noted that the grid-like visual pattern 12 may be formed by printing a plurality of ink dots on the surface 11 of the polymer resin film 1 by, for example, a transfer method using a printing roller or a digital ink jet method, but the present invention is not limited thereto.

Furthermore, the color of the plurality of ink dots 12 is preferably different from the color of the surface 11 of the polymer resin film 1, so that the grid-shaped visual pattern 12 can be clearly displayed.

As shown in fig. 7, the grid-shaped visual pattern 12 on the surface 11 of the polymer resin film 1 includes a plurality of geometric lines 121 and a plurality of geometric figures 122.

The geometric lines 121 are connected to each other in a staggered manner and have a first color. Furthermore, the geometric figures 122 are respectively located between the geometric lines 121 and have a second color different from the first color.

It is worth mentioning that, in order to make the grid-like visual pattern 12 clearly appear, there must be a distinct difference between the first color of the geometric lines 121 and the second color of the geometric figures 122.

For example, the first color may be, for example, one of a dark color or a light color, and the second color may be, for example, the other of the dark color or the light color.

The dark color may be dark color such as black, dark gray, dark blue, dark purple, dark brown, etc., and the light color may be light color such as white, light gray, light red, light yellow, light green, etc., but the present invention is not limited thereto, and the mesh-like visual pattern 12 can be clearly displayed by the color matching manner of the first color and the second color, which is in accordance with the protection spirit of the present invention and falls within the protection scope of the present invention.

Referring to fig. 7, in the present embodiment, the geometric lines 121 of the grid-shaped visual pattern 12 are straight lines criss-cross connected to each other, and the geometric figures 122 of the grid-shaped visual pattern 12 are respectively located between the geometric lines 121 and defined by the geometric lines 121. In the present embodiment, the geometric figures 122 are respectively shown as squares, but the invention is not limited thereto.

For example, in other embodiments of the invention, the geometric lines 121 may be non-linear lines (e.g., curved lines, polygonal lines), and the geometric figures 122 may also be hexagonal (e.g., fig. 8) or irregular curved (e.g., fig. 9) according to the requirement of the product; alternatively, in an embodiment not shown in the present invention, the geometric figures 122 may also be respectively in a circular shape, a diamond shape, a triangular shape, or other shapes according to the requirement of the product.

More specifically, in the present embodiment, the geometric lines 121 of the visual grid pattern 12 are respectively formed by a plurality of ink dots, and the ink dots have the first color (e.g., dark color). Thus, a plurality of said geometric lines 121 can exhibit said first color; furthermore, the surface 11 of the polymer resin film 1 itself is the second color (e.g., light color), and therefore, the geometric figures 122 defined by the geometric lines 121 and not covered by the geometric lines 121 can be the second color, but the invention is not limited thereto.

For example, in an embodiment not shown in the present invention, the geometric figures 122 of the grid-like visual pattern 12 may also be formed by a plurality of ink dots, for example, and the plurality of ink dots have the second color. Thus, a plurality of the geometric shapes 122 can present the second color. Furthermore, the surface 11 of the polymer resin film 1 itself exhibits the first color, and thus the geometric lines 121 defined by the geometric figures 122, which are not covered by the geometric figures 122, can exhibit the first color.

Alternatively, in another embodiment of the present invention, which is not shown in the drawings, the geometric lines 121 of the grid-shaped visual pattern 12 may also be formed by a plurality of ink dots, for example, and the plurality of ink dots have the first color, so that the geometric lines 121 can show the first color. Furthermore, the geometric figures 122 of the grid-like visual pattern 12 may be formed by another ink dots, for example, and the another ink dots have the second color, so that the geometric figures 122 can present the second color.

Since the mesh-shaped visual patterns 12 can only provide the visual effect of arranging another layer of mesh on the polymer resin film 1, but cannot provide the tactile effect and the touch feeling of the mesh, in this embodiment, the film-shaped material 100 further includes the tactile structure module 2 to further provide the tactile effect and the touch feeling of the mesh to the film-shaped material 100 without affecting the visual effect of the mesh-shaped visual patterns 12.

Referring to fig. 1 to 3, the tactile structure module 2 is disposed on the surface 11 (e.g., the upper surface of fig. 3) of the polymer resin film 1 and partially covers the grid-shaped visual pattern 12.

More specifically, the haptic structure module 2 includes a plurality of stereo colloids 21 (e.g., resin colloids). The three-dimensional colloids 21 have translucency, for example, the three-dimensional colloids 21 are transparent, translucent, or misty.

Furthermore, a plurality of the stereo colloids 21 are arranged on the surface 11 of the polymer resin film 1 at intervals so as to partially cover the grid-shaped visual pattern 12. That is, a portion of the grid-shaped visual pattern 12 is covered by the plurality of stereo colloids 21, and another portion of the grid-shaped visual pattern 12 is exposed to the external environment through the gaps between the plurality of stereo colloids 21.

Since the plurality of stereo colloids 21 are all light-transmitting, the grid-shaped visual pattern 12 on the surface 11 of the polymer resin film 1 can be seen through by the plurality of stereo colloids 21 and appears on one side of the surface 11 of the polymer resin film 1.

In other words, when a user views the grid-shaped visual pattern 12 from the side of the surface 11 of the polymer resin film 1, the visual effect of the grid-shaped visual pattern 12 is not affected (e.g., blocked) by the plurality of stereo colloids 21 and can be completely displayed in the eyes of the user.

In the present embodiment, the plurality of stereo colloids 21 of the tactile structure module 2 may be, for example, a screen printing method or a stamp roller transfer method, in which the plurality of stereo colloids 21 having a stereo structure are disposed on the grid-shaped visual pattern 12 on the surface 11 of the polymer resin film 1, but the present invention is not limited thereto.

It should be noted that, since the visual effect of the grid-shaped visual pattern 12 of the present embodiment is not affected by the plurality of stereo colloids 21, the positions of the plurality of stereo colloids 21 on the grid-shaped visual pattern 12 are not particularly limited.

For example, in the present embodiment, the plurality of stereo colloids 21 may be partially disposed on the geometric lines 121 and partially disposed on the geometric figures 122, but the plurality of stereo colloids 21 do not affect the appearance of the geometric lines 121 and the geometric figures 122.

As shown in fig. 3 and fig. 4, in the present embodiment, each of the three-dimensional colloids 21 includes: a polymer resin material 211 and a plurality of insoluble solid particles 212 dispersed in the polymer resin material 211. In each of the three-dimensional colloids 21, at least a portion of the insoluble solid particles 212 in the plurality of insoluble solid particles 212 is located on a surface layer of the three-dimensional colloid 21 and is partially exposed to the external environment, so as to provide a user with a touch (see fig. 4). Therefore, the film-shaped material 100 can have a tactile effect and a touch feeling equivalent to those of a mesh.

Further, in each of the stereo colloids 21, the polymer resin material 211 is an aqueous polymer resin material. The aqueous polymer resin material may be, for example, an aqueous Polyurethane (PU) resin material, an aqueous Polyester (PE) resin material, an aqueous acrylic resin material, or an aqueous alkyd resin material …. In the present embodiment, the aqueous polymer resin material 211 is preferably at least one of an aqueous polyurethane resin material and an aqueous acrylic resin material, but the present invention is not limited thereto.

It should be noted that, since the above-mentioned aqueous polyurethane resin material and the aqueous acrylic resin material have good transparency, hardness and adhesiveness, these aqueous polymer resin materials can provide the plurality of stereo colloids 21 with good transparency and hardness, and can allow the plurality of stereo colloids 21 to be stably disposed on the surface 11 of the polymer resin film 1 without easily falling off.

In addition, it should be noted that, since the polymer resin material 211 is an aqueous polymer resin material, in the embodiment, the composition of the stereo colloid 21 does not include Volatile Organic Solvents (VOCs). For example, the volatile organic solvent may be acetone, but the present invention is not limited thereto. Therefore, the film material 100 of the present embodiment has the advantages of low toxicity, environmental friendliness, and human friendliness.

Further, since the polymer resin film 1 is preferably a Polyurethane (PU) resin film, a Thermoplastic Polyurethane (TPU) resin film, polyethylene terephthalate (PET), or a composite film including at least two materials thereof, and the aqueous polymer ink of the mesh-like visual pattern 12 is preferably an aqueous polyurethane ink or an aqueous acrylic ink or a composite ink of the two materials. Therefore, the plurality of the stereo colloids 21 (the main material is also polyurethane or acryl) can be firmly adhered to the polymer resin film 1 without easily falling off (the materials have good affinity) regardless of being in contact with the surface 11 of the polymer resin film 1 or being in contact with the grid-shaped visual patterns 12 formed thereon.

It should be noted that although the ink of the present embodiment is an "aqueous" polymer ink and the polymer resin material 211 is an "aqueous" polymer resin material, the present invention is not limited thereto. For example, in another embodiment of the present invention, the ink may be a "solvent-based" polymer ink, and the polymer resin material 211 may be a "solvent-based" polymer resin material.

As shown in fig. 3 and fig. 4, in the present embodiment, a plurality of the insoluble solid particles 212 are evenly dispersed in the polymer resin material 211, and the insoluble solid particles 212 on the surface layer of the solid colloid 21 are partially exposed to the external environment to provide a touch for a user.

As shown in fig. 5, in an alternative embodiment of the present invention, the plurality of insoluble solid particles 212 are only distributed on the surface layer of the solid colloid 21 and are partially exposed to the external environment, and no insoluble solid particles 212 are distributed on the inner side of the solid colloid 21.

That is, the haptic structure module 2 only has the structural features that the insoluble solid particles 212 are distributed on the surface layer of the three-dimensional colloid 21 and are partially exposed to the external environment, which is consistent with the protection spirit of the present invention, and thus, the haptic structure module belongs to the protection scope of the present invention.

As shown in fig. 3, in each of the stereo colloids 21, each of the insoluble solid particles 212 is dispersed but not dissolved in the polymer resin material 211. That is, each of the insoluble solid particles 212 retains the original material shape in the polymer resin material 211, and each of the insoluble solid particles 212 has a distinct interface with the polymer resin material 211.

Further, in each of the stereo colloids 21, a mohs hardness of each of the insoluble solid particles 212 is different from a mohs hardness of the polymer resin material 211.

In the present embodiment, the mohs hardness of each of the insoluble solid particles 212 is greater than the mohs hardness of the polymer resin material 211. Therefore, the mesh fabric touch effect and touch feeling of the film material 100 can be effectively improved.

Specifically, each of the insoluble solid particles 212 has a mohs hardness of approximately 4 to 10, and the polymer resin material 211 has a mohs hardness of approximately 1 to 4, but the present invention is not limited thereto.

It is worth mentioning that the hardness of the general polymer resin material (such as polyurethane or acryl) is low, which cannot provide sufficient mesh fabric tactile effect. Accordingly, in order to provide a sufficient mesh tactile effect, the plurality of hydrocolloids 21 of the tactile structure module 2 of the present embodiment are further added with insoluble solid particles having a high hardness. Thereby, the overall hardness of the plurality of the cubic colloids 21 can be effectively improved.

Furthermore, since the insoluble solid particles 212 are distributed on the surface layer of the three-dimensional colloid 21 and are partially exposed to the external environment, when a user touches the film-like material 100, the user can touch the polymer resin material 211 and the insoluble solid particles 212 of the tactile structure module at the same time (see fig. 4). Thereby, the film-like material 100 can provide the user with sufficient net tactile effect.

Please continue to refer to fig. 3 and 4. In each of the three-dimensional colloids 21, the insoluble solid particles 212 on the surface layer of the three-dimensional colloid 21 partially protrude from the outer surface of the three-dimensional colloid 21 and are partially embedded in the three-dimensional colloid 21, but the invention is not limited thereto.

For example, as shown in fig. 6, in a variation of the present invention, the insoluble solid particles 212 on the surface layer of the three-dimensional colloid 21 are partially exposed and cut off from the outer surface of the three-dimensional colloid 21 and partially embedded in the three-dimensional colloid 21. In this variation, when a user touches the film-like material 100, the user can still touch the polymer resin material 211 and the insoluble solid particles 212 of the tactile structure module at the same time, so as to feel a sufficient mesh tactile effect.

In terms of the type of material, the insoluble solid particles are at least one of inorganic solid particles and organic solid particles.

The material of the inorganic solid particles may be at least one of silica, titania, iron oxide, and metal hydroxide, for example. The organic solid particles may be, for example, at least one of polymer resin particles (e.g., plastic particles), siloxy particles, and plant-derived particles (e.g., coffee grounds).

It is worth mentioning that the material source of the plurality of said insoluble solid particles may also be, for example, recycled materials, such as: recovered coffee grounds, waste fishing nets, or leftovers … of electronic parts, and the like. Therefore, the film material 100 of the present embodiment can further meet the requirements of environmental protection and energy saving.

Furthermore, in order to make the plurality of insoluble solid particles 212 more uniformly dispersed in the polymer resin material 211, in each of the stereo colloids 21, the composition of the stereo colloid 21 further includes a bridging agent (not shown), and the bridging agent is configured to assist the plurality of insoluble solid particles 212 to be dispersed in the polymer resin material 211.

In this embodiment, the bridging agent is at least one of an aliphatic isocyanate bridging agent and a melamine bridging agent. Furthermore, the content range of the bridging agent in the stereo colloid 21 is preferably between 1 wt% and 10 wt%, and particularly preferably between 3 wt% and 5 wt%, but the invention is not limited thereto.

As shown in fig. 1 to fig. 3, the sizes, the arrangement manners, and the arrangement densities of the three-dimensional colloids 21 of the haptic structure module 2 of the present embodiment have a better configuration manner.

Specifically, the plurality of stereo colloids 21 of the tactile structure module 2 are arranged in a matrix (as shown in fig. 1) or in a staggered (not shown) on the surface 11 of the polymer resin film 1. In addition, the plurality of the stereo colloids 21 of the haptic structure module 2 are not directly connected to each other.

Furthermore, as shown in fig. 3, each of the stereo colloids 21 has a width W between 50 μm and 1,000 μm and a height H between 100 μm and 1,000 μm, and a distance D between each stereo colloid 21 and its adjacent stereo colloid 21 is between 50 μm and 2,000 μm.

In addition, the coverage rate of the plurality of stereo colloids 21 of the tactile structure module 2 on the surface 11 of the polymer resin film 1 is preferably between 20% and 90%, and particularly preferably between 50% and 80%.

According to the above configuration, the tactile structure module 2 of the film-like material 100 of the present embodiment can be used to provide the tactile effect and touch feeling equivalent to the mesh cloth without affecting the visual effect of the grid-like visual pattern 12.

The width W of the steric colloid 21 is defined as the maximum width of the steric colloid 21 parallel to the surface 11 of the polymer resin film 1. The height H of the steric colloid 21 is defined as the maximum height of the steric colloid 21 perpendicular to the surface 11 of the polymer resin film 1. The above-mentioned distance D is defined as the shortest distance between each of the stereo colloids 21 and its adjacent stereo colloid 21.

Further, the range of the particle size and the range of the content of the insoluble solid particles 212 in the embodiment also have a preferable configuration.

Specifically, in each of the stereo colloids 21, a plurality of the insoluble solid particles 212 respectively have a particle size range between 20 micrometers and 150 micrometers, and preferably between 60 micrometers and 120 micrometers. Furthermore, the content of the insoluble solid particles 212 in the stereo colloid 21 is in a range from 1 wt% to 10 wt%, and preferably from 3 wt% to 7 wt%. Whereby each of the stereo colloids has a transmittance of not less than 50%, and preferably not less than 70%.

If the particle size range and/or the content range of the plurality of insoluble solid particles 212 is higher than the upper limit value of the above range, the transmittance of the plurality of the stereo colloids 21 becomes insufficient and may not be firmly adhered to the surface 11 of the polymer resin film 1.

On the contrary, if the particle size range and/or the content range of the insoluble solid particles 212 is lower than the lower limit of the above range, the plurality of the steric colloids 21 may not provide sufficient net feeling effect.

As shown in fig. 3, in a cross section of the film-like material 100 of the present embodiment, the plurality of the stereo colloids 21 are respectively in a semicircular shape, but the present invention is not limited thereto.

For example, the stereo colloids 21 may be rectangular (as shown in fig. 10), circular (as shown in fig. 11), or other shapes that can provide the tactile effect and touch feeling of the mesh.

It is worth mentioning that the polymer resin film 1 of the present embodiment may be a product that is sold separately, and may be further applied to other objects.

For example, as shown in fig. 12, the other surface 13 of the polymer resin film 1 opposite to the tactile structure module 2 of the present embodiment can be used for bonding to a textile. Thereby, the structural strength of the film-like material 100 can be reinforced.

The textile fabric has a plurality of warp yarns and a plurality of weft yarns (not numbered) that are interlaced with each other, or the textile fabric may be, for example, a polyester fiber, a polyamide fiber, a polypropylene fiber, an acrylic fiber, or an elastic fiber (not shown).

[ second embodiment ]

Please refer to fig. 13, which illustrates a second embodiment of the present invention. This embodiment is substantially the same as the first embodiment described above, except that the film-like material 100' of this embodiment does not have the grid-like visual pattern 12.

Specifically, the film material 100' of the present embodiment includes a polymer resin film 1 and a haptic structure module 2. The tactile structure module 2 comprises a plurality of stereo colloids 21. The plurality of the stereo colloids 21 are arranged on one surface 11 of the polymer resin film 1 at intervals. Wherein, each of the three-dimensional colloids 21 comprises: a polymer resin material 211 and a plurality of insoluble solid particles 212 dispersed in the polymer resin material 211. At least a portion of the insoluble solid particles 212 in the plurality of insoluble solid particles 212 is located on a surface layer of the three-dimensional colloid 21 and is partially exposed to the external environment, so as to provide a user with a touch.

[ third embodiment ]

The third embodiment of the present invention provides a method for manufacturing a film-like material (not shown).

The step S140 includes: the liquid components (such as moisture) in the liquid pastes are evaporated so that the liquid pastes are respectively formed into a plurality of stereo colloids 21 adhered to the surface 11 of the polymer resin film 1, and the stereo colloids 21 partially cover the grid-shaped visual pattern 12.

The liquid component may be evaporated by, for example, baking (e.g., 80 to 150 ℃) to cause a curing reaction of the polymer resin material 211 in the plurality of liquid pastes. In the curing process, the liquid pastes are formed into a plurality of three-dimensional colloids 21 adhering to the surface 11 of the polymer resin film 1.

Further, in each of the three-dimensional colloid 21, at least a portion of the insoluble solid particles 212 in the plurality of insoluble solid particles 212 is located on a surface layer of the three-dimensional colloid 21 and is partially exposed to the external environment, so as to provide a user with a touch.

Furthermore, the plurality of stereo colloids 21 are all light-transmitting, so that the grid-shaped visual pattern 12 on the surface 11 of the polymer resin film 1 can be seen through by the plurality of stereo colloids 21 and appears on one side of the surface 11 of the polymer resin film 1.

[ fourth embodiment ]

This embodiment is substantially the same as the above-described embodiment except that the insoluble solid particles 212 of the film-like material 100 ″ of this embodiment are provided in the polymer resin film 1.

Specifically, the film material 100 ″ of the present embodiment includes a polymer resin film 1 and a haptic structure module 2. One surface 11 of the polymer resin film 1 is colored with a grid-like visual pattern 12.

The tactile structure module 2 includes a plurality of insoluble solid particles 212, and the plurality of insoluble solid particles 212 are dispersed in the polymer resin film 1. At least a part of the insoluble solid particles 212 in the plurality of insoluble solid particles 212 are located on the surface layer of the polymer resin film 1 and partially protrude from the surface 11 of the polymer resin film 1 to provide a user with touch.

[ advantageous effects of the embodiments ]

One of the advantages of the present invention is that the film-like material with a tactile structure and the manufacturing method thereof provided by the present invention can be obtained by "the composition of each of the three-dimensional colloids comprises: a polymer resin material and a plurality of insoluble solid particles dispersed in the polymer resin material; wherein at least a portion of the insoluble solid particles in the plurality of insoluble solid particles are located on a surface layer of the three-dimensional colloid and partially exposed to an external environment, so as to provide a user with a touch, "and" the three-dimensional colloids have light transmittance, so that the grid-shaped visual pattern on the surface of the polymer resin film can be seen through by the three-dimensional colloids and is present on one side of the surface of the polymer resin film, "so that the film-shaped material has a visual effect of a double-layer cloth and a sufficient net-shaped tactile effect under a condition of light and thin thickness.

Furthermore, the film-shaped material according to the embodiment of the invention can provide a visual effect of disposing another layer of mesh on the polymer resin film by having the mesh-shaped visual pattern on the surface of the polymer resin film, and can further provide the tactile effect and the touch feeling of the mesh by disposing the plurality of stereo colloids of the tactile structure module without affecting the visual effect of the mesh-shaped visual pattern.

In addition, the film material of the embodiment of the present invention shows the visual effect of the double-layer fabric by the grid-shaped visual pattern, but the polymer resin film actually has a structure of only a single-layer fabric. Therefore, the thickness and weight of the film-shaped material are lower than those of the conventional film-shaped material having a base fabric and a mesh fabric, and the manufacturing process of attaching the mesh fabric to the base fabric can be omitted in manufacturing the film-shaped material of this embodiment.

More specifically, for the prior double-layer film-shaped material with a layer of base cloth and a layer of mesh cloth, the weight of the double-layer film-shaped material is at least higher than 50g/m although the mesh cloth material is the lightest weight². The weight of the film-like material of the embodiment of the present invention (single layer film-like material having a double visual effect) can be greatly reduced to 50g/m, compared to the above-mentioned conventional double layer film-like material²The requirements of some end products for light weight can be met as follows.

It is worth mentioning that, the currently marketed cloth with a low denier number of 10 denier will possibly develop a cloth with a lower denier number when the textile technology is further advanced in the future, and if the cloth with the lower denier number is adopted as the substrate of the film-like material of the embodiment of the present invention, the weight of the film-like material of the embodiment of the present invention may be reduced to 40g/m²The following.

The disclosure is only a preferred embodiment of the invention and should not be taken as limiting the scope of the invention, so that the invention is not limited by the disclosure of the specification and drawings.
