Description

TECHNICAL FIELD The present invention relates to a membrane material, and more particularly to a membrane material having a special tactile structure and a manufacturing method thereof.

A conventional membrane material having a mesh cloth has a problem that it is necessary to attach the mesh cloth layer to the base fabric layer as a double layer, and the processing is relatively complicated. In addition, since the above-described membrane material has a two-layer fabric structure, there is a problem that the thickness is increased and the weight is increased. Therefore, for some end-use products (i.e., functional clothing) that require simple processing procedures, thin thickness, and light weight, the film material meets the needs of these end-use products. It is clear that it cannot.

The problem to be solved by the present invention is to provide a membrane material with a special tactile structure and a manufacturing method thereof to meet the existing shortage.

In order to solve the above technical problems, one of the technical means adopted by the present invention is to provide a film material as a single layer structure having a special tactile structure including a polymer resin film and a special tactile structure module. That is. The surface of the polymer resin film is colored to form a grid-like visual pattern. The special tactile structure module includes a plurality of three-dimensional structures, and the plurality of three-dimensional structures are spaced apart from each other and arranged on the surface of the polymer resin film, thereby partially forming the grid-like visual pattern. effectively cover. Among other things, each of the three-dimensional structures includes a polymeric resin material and a plurality of insoluble solid mixtures dispersed in the polymeric resin material. In particular, at least a portion of the insoluble solid mixture in the plurality of insoluble solid mixtures is located on the surface layer of the three-dimensional structure and partially exposed to the external environment for user contact. In particular, since all of the plurality of three-dimensional structures have visible light transmittance, the grid-like visual pattern on the surface of the polymer resin film can be transmitted through the plurality of three-dimensional structures and the high-visibility light. It becomes visible on one side of said surface of the molecular resin film.

Another technical means adopted by the present invention to solve the above technical problems is to provide a method for producing a membrane material. A method of manufacturing a membrane material provides a polymeric resin membrane. An ink material is printed on one surface of the polymer resin film according to a predetermined pattern, and a liquid component is evaporated from the ink material to form a grid-like visual pattern on the surface of the polymer resin film. A plurality of liquid pastes are formed on the surface of the polymer resin film. In particular, a plurality of the liquid glues are formed on the surface of the polymer resin film at intervals. Each of the liquid pastes comprises a polymer resin material and a plurality of insoluble solid mixtures dispersed in the polymer resin material. By evaporating a liquid component from the plurality of liquid pastes, each of the plurality of liquid pastes is formed as a plurality of three-dimensional structures adhered to the surface of the polymer resin film, and the plurality of three-dimensional structures are formed. The body partially covers the grid visual pattern. Among other things, in each of the three-dimensional structures, at least a portion of the insoluble solid mixture in the plurality of the insoluble solid mixtures is located on the surface layer of the three-dimensional structure and is partially exposed to the external environment for contact by a user. exposed. In particular, since all of the plurality of three-dimensional structures have visible light transmittance, the grid-like visual pattern on the surface of the polymer resin film can be transmitted through the plurality of three-dimensional structures, It becomes visible on one side of the surface of the polymer resin film.

One of the beneficial effects of the present invention is that the film material as a single-layer structure having a special tactile structure provided by the present invention and the method for producing the same are such that "each three-dimensional structure is composed of a polymer resin material and a plurality of insoluble solid mixtures dispersed in the polymeric resin material, wherein at least a portion of the insoluble solid mixtures in the plurality of insoluble solid mixtures are located on the surface layer of the three-dimensional structure and , are partially exposed to the external environment for the user to touch." A visual pattern in the shape of a mesh penetrates the plurality of three-dimensional structures and can be visually recognized on the surface of the polymer resin film." In order to provide a film material with sufficient tactile effect, it is desirable to provide a film material having the visual effect of a double layer (not triple layer) fabric and the tactile effect of a mesh.

[First Embodiment]
Please refer to FIGS. 1-3. 1 to 3 show a first embodiment according to the invention. The relevant quantities and appearances described in the corresponding drawings of the present embodiment are only used to specifically illustrate the embodiments of the present disclosure for understanding the content of the present disclosure, and the protection scope of the present disclosure is not limited. Note that it is not used for limiting.

This embodiment discloses a film material 100 including a polymer resin film 1 and a special tactile structure module 2 disposed on the polymer resin film 1 .

The polymer resin film 1 has two corresponding surfaces and one surface 11 of the polymer resin film 1 is colored to form a grid-like visual pattern 12 .

The polymer resin film 1 is in the form of a film with a thickness of 5 μm to 50 μm.

The polymer resin film 1 is made of, for example, polyurethane (PU) resin film, thermoplastic polyurethane (TPU) resin film, polytetrafluoroethylene (PTFE) resin film, polyethylene (PE) resin film, polypropylene (PP) resin film, polyethylene At least one of a terephthalate (PET) resin film, a latex film, a polyester elastomer film, and a polymer composite film may be used. In this embodiment, the polymer resin film 1 is preferably a polyurethane (PU) resin film, a thermoplastic polyurethane (TPU) resin film, a polyethylene terephthalate (PET) resin film, a latex film, or a polyester elastomer film. The invention is not limited to this.

The grid-like visual pattern 12 is a planar printed pattern having a grid-like pattern, and can exhibit a visual effect that another mesh-like layer is arranged on the polymer resin film 1 . That is, although the polymer resin film 1 actually has a structure of only a single-layer fabric, it can exhibit a visual effect of having a two-layer fabric through the grid-like visual pattern 12 .

A surface 11 of the polymer resin film 1 is a substantially flat surface. The grid-like visual pattern 12 is composed of a plurality of ink dots regularly arranged on the surface 11 of the polymer resin film 1 . The plurality of ink dots and the surface 11 of the polymer resin film 1 are substantially coplanar with each other.

Since the thickness of the ink dots forming the grid-like visual pattern 12 is relatively thin (for example, 20 μm or less), there is a large gap between the grid-like visual pattern 12 and the surface 11 of the polymer resin film 1 . There is no difference. Therefore, the grid-like visual pattern 12 formed by a plurality of ink dots can only be used to give the visual effect that another mesh layer is arranged on the polymer resin film 1, and the mesh fabric can be used. It cannot be used to impart tactile sensations or textures.

In the grid-like visual pattern 12, the plurality of ink dots are aqueous polymer ink dots.

Aqueous polymeric ink dots may include, for example, aqueous polymeric resins, emulsifiers, organic or inorganic pigments, solvents, and related additives. The aqueous polymer resin may be, for example, an aqueous polyurethane resin, an aqueous polyester resin, an aqueous acrylic resin, an aqueous alkyd resin, or the like. Examples of the solvent include mainly water, alcohol, and the like.

The water-based polymer ink is preferably at least one of water-based polyurethane ink and water-based acrylic ink, but the present invention is not limited thereto.

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 using a printing roller transfer method or a digital inkjet method.

The colors of the plurality of ink dots 12 preferably have a large color difference from the surface 11 of the polymer resin film 1, so that the grid-like visual pattern 12 can be clearly presented.

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

Also, the plurality of geometric lines 121 are cross-connected with each other and have a first color. Moreover, the plurality of geometric figures 122 are each arranged between the plurality of geometric lines 121 and have a second color different from the first color.

In order to make it possible to present the grid-like visual pattern 12 clearly, there is a gap between the first color of the plurality of geometric lines 121 and the second color of the plurality of geometric figures 122. There must be considerable color difference.

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

Referring again to FIG. 7, the plurality of geometric lines 121 of the grid visual pattern 12 are straight lines that intersect each other and are connected. The plurality of geometric figures 122 of the grid visual pattern 12 are respectively arranged between and defined by the plurality of geometric lines 121 . Although each of the plurality of geometric figures 122 is presented as a square in this embodiment, the disclosure is not so limited.

Also, the plurality of geometric lines 121 may be non-linear such as curves or polylines. The plurality of geometric figures 122 may be presented as hexagonal figures as shown in FIG. 8 or as irregular curves as shown in FIG. 9, depending on product requirements. . In a non-illustrated embodiment of the present invention, the plurality of geometric figures 122 may also each be presented as circles, diamonds, triangles, or other shapes, depending on textile product requirements.

A plurality of geometric lines 121 of the grid-like visual pattern 12 are each composed of ink dots, the ink dots having a first color, for example a dark color. As such, the plurality of geometric lines 121 can exhibit a first color. Moreover, the surface 11 itself of the polymer resin film 1 exhibits a second color, for example, a light color. As such, the plurality of geometric figures 122 not covered by the plurality of geometric lines 121 and defined by the plurality of geometric lines 121 can exhibit the second color. However, the present invention is not limited to this.

The grid-like visual pattern 12 can only provide a visual effect when another mesh layer is arranged on the polymer resin film 1, but cannot provide the tactile feel and feel of the mesh fabric. The film material 100 further includes a special tactile structure module 2 so that the tactile feel and feel of the mesh fabric can be obtained without affecting the visual effect of the grid-like visual pattern 12 .

Referring to FIGS. 1 to 3 again, the special tactile structure module 2 is arranged on the surface 11 of the polymer resin film 1 and arranged to partially cover the grid-like visual pattern 12 .

The special tactile structure module 2 includes a plurality of three-dimensional structures 21, all of which have visible light transmittance.

The plurality of three-dimensional structures 21 are arranged on the surface 11 of the polymer resin film 1 with a space between them, thereby partially covering the grid-like visual pattern 12 . That is, a portion of the grid-like visual pattern 12 is covered with the plurality of three-dimensional structures 21, and the other portion of the grid-like visual pattern 12 is exposed to the outside through the spaces between the plurality of three-dimensional structures 21. Become exposed in relationships.

Since all of the plurality of three-dimensional structures 21 have visible light transmittance, the grid-like visual pattern 12 on the surface 11 of the polymer resin film 1 is transmitted through the plurality of three-dimensional structures 21, and the polymer resin film 1 becomes visible on one side of the surface 11 of the .

In the present embodiment, the plurality of three-dimensional structures 21 in the special tactile structure module 2 may be formed by, for example, an imitation mesh processing method, or a printing roller transfer method may be used to form a grid pattern on the surface 11 of the polymer resin film 1. A plurality of three-dimensional structures 21 having a three-dimensional structure may be arranged in the visual pattern 12, but the present invention is not limited to this example.

In this embodiment, the plurality of 3D structures 21 may be partially arranged in geometric lines 121 and partially arranged in geometric figures 122, but the 3D structures 21 may be arranged in geometric It does not affect the presentation of geometric lines 121 and geometric figures 122 .

Please refer to FIGS. 3 and 4 again. Each configuration of three-dimensional structure 21 includes polymeric resin material 211 and a plurality of insoluble solid mixtures 212 dispersed in polymeric resin material 211 . In each of the three-dimensional structures 21, at least some of the insoluble solid mixtures 212 in the plurality of insoluble solid mixtures 212 are located on the surface layer of the three-dimensional structure 21 and partially exposed to the external environment for touching by the user. (as shown in Figure 4). As such, the membrane material 100 can have a tactile feel or feel similar to that of a mesh fabric.

In each three-dimensional structure 21, the polymer resin material 211 is an aqueous polymer resin material. Examples of water-based polymer resin materials include water-based polyurethane (PU) resin materials, water-based polyester resin materials, water-based acrylic resin materials, and water-based alkyd resin materials. In this 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 to this.

Since the water-based polyurethane resin material and the water-based acrylic resin material both have good transparency, hardness, and adhesion, the use of these water-based polymer resin materials improves the transparency and hardness of the plurality of three-dimensional structures 21. It is possible to stably arrange the plurality of three-dimensional structures 21 on the surface 11 of the polymer resin film 1 without peeling off easily.

Since the polymeric resin material 211 is an aqueous polymeric resin material, the three-dimensional structure 21 of this embodiment does not contain volatile organic solvents (VOCs). The volatile organic solvent may be, for example, acetone, but the invention is not limited thereto. The membrane material 100 of the present embodiment can have advantages such as low toxicity, environmental friendliness, and human body friendliness.

As described above, the polymer resin film 1 is preferably a polyurethane (PU) resin film, a thermoplastic polyurethane (TPU) resin film, a polyethylene terephthalate (PET) resin film, a latex film, a polyester elastomer film, or a polymer composite film. Or a composite film comprising at least two materials as described above. And the water-based polymeric ink of the grid-like visual pattern 12 is preferably water-based polyurethane ink or water-based acrylic ink, or a composite ink of the two materials. Therefore, even if a plurality of three-dimensional structures 21 are in contact with the surface 11 of the polymer resin film 1 or in contact with the grid-like visual pattern 12 formed thereon, the three-dimensional structures 21 are easily peeled off. It can be firmly adhered to the polymer resin film 1 without removing the film.

In this embodiment, the ink is an "aqueous" polymeric ink, and the polymeric resin material 211 of the present embodiment is an "aqueous" polymeric resin material, but the present invention is not limited to this. For example, in another embodiment of the invention, the ink may be a "solvent based" polymeric ink and the polymeric resin material 211 may be a "solvent based" polymeric resin material.

Referring to FIGS. 3 and 4 again, a plurality of insoluble solid mixtures 212 are uniformly dispersed in the polymer resin material 211, and the insoluble solid mixtures 212 located on the surface of the three-dimensional structure 21 can be touched by the user. are partially exposed to the external environment.

As shown in FIG. 5 , in a variation of the present disclosure, the plurality of insoluble solid mixtures 212 are distributed only on the surface layer of the three-dimensional structure 21 and are partially exposed to the external environment. No insoluble solid mixture 212 is distributed inside.

That is, as long as the special tactile structure module 2 has a structural feature that the insoluble solid mixture 212 is distributed on the surface layer of the three-dimensional structure 21 and partially exposed to the external environment, this structural feature is fall within the spirit and scope of the invention.

Referring again to FIG. 3, in each three-dimensional structure 211, each insoluble solid particle 212 is dispersed in polymeric resin material 211, but is not dissolved. That is, each of the insoluble solid mixtures 212 retains its original material shape within the polymeric resin material 211, and a distinct interface is formed between each of the insoluble solid mixtures 212 and the polymeric resin material 211. It is

The Mohs hardness of each insoluble solid mixture 212 of each three-dimensional structure 21 is different from the Mohs hardness of the polymeric resin material 211 .

In this embodiment, the Mohs hardness of each insoluble solid mixture 212 is greater than the Mohs hardness of the polymeric resin material 211 . In this way, the mesh-like tactile effect and texture of the film material 100 can be effectively improved.

Each of the insoluble solid mixtures 212 has a Mohs hardness of about 4-10, and the polymeric resin material 211 has a Mohs hardness of about 1-4, but the invention is not so limited.

It should be noted that common polymeric resin materials (eg, polyurethane, acrylic, etc.) have low hardness and cannot achieve a sufficient mesh tactile effect. Therefore, the three-dimensional structures 21 of the special tactile structure module 2 of this embodiment are further added with an insoluble solid mixture with higher hardness to provide a sufficient mesh fabric tactile effect. . As such, the overall hardness of the three-dimensional structures 21 can be effectively improved.

The insoluble solid mixture 212 is distributed on the surface layer of the three-dimensional structure 21 and partially exposed to the external environment. The solid mixture 212 can be touched at the same time (as shown in FIG. 4). The user can feel a good mesh texture from the membrane material 100 .

3 and 4, in each three-dimensional structure 21, the insoluble solid mixture 212 on the surface of the three-dimensional structure 21 partially protrudes from the outer surface of the three-dimensional structure 21 and partially extends into the three-dimensional structure 21. , but the invention is not so limited.

As shown in FIG. 6, in a modification of the present invention, the insoluble solid mixture 212 on the surface of the three-dimensional structure 21 is partially exposed from the outer surface of the three-dimensional structure 21 and They are aligned and partially embedded in the three-dimensional structure 21 . In this variant, even if the user touches the membrane material 100, the user can touch the polymer resin material 211 and the insoluble solid mixture 212 of the special tactile structure module 2 at the same time, thereby providing sufficient mesh fabric. You can feel the touch of

The plurality of insoluble solids mixture is at least one of inorganic solid particles and organic solid particles.

The material of the inorganic solid particles may be, for example, at least one of silicon dioxide, titanium dioxide, iron oxide, and metal hydroxide. The organic solid particles may be at least one of polymeric resin particles (eg, plastic particles), siloxane particles, plant-derived particles (eg, coffee grounds).

The source of the plurality of insoluble solids mixtures may also be recycled materials, such as recycled coffee grounds, discarded fishing nets, electronic scraps, and the like. As such, the film material 100 of the present embodiment can further meet the requirements of environmental protection and energy saving.

In order to more evenly disperse the plurality of insoluble solid mixtures 212 in the polymeric resin material 211, the composition of each three-dimensional structure 21 further includes a cross-linking agent, which causes the plurality of insoluble solid mixtures 212 to become polymeric. It is configured to assist in being dispersed in the resin material 211 .

In this embodiment, the cross-linking agent is at least one of an isocyanate cross-linking agent, a melamine cross-linking agent, and an aziridine cross-linking agent. % to 10% by weight, more preferably 3% to 5% by weight, but the present invention is not limited thereto.

Referring to FIGS. 1 to 3 again, the size, arrangement, and distribution density of the plurality of three-dimensional structures 21 of the special tactile structure module 2 of this embodiment have favorable configurations.

A plurality of three-dimensional structures 21 of the special tactile structure module 2 are arranged in a matrix on the surface 11 of the polymer resin film 1 (as shown in FIG. 1) or arranged in a zigzag pattern ( not shown in the drawing). The multiple three-dimensional structures 21 of the special tactile structure module 2 are not in direct contact with each other.

As shown in FIG. 3, each three-dimensional structure 21 has a width (W) of 30 μm to 1,000 μm, a height (H) of 100 μm to 1,000 μm, and is adjacent to each three-dimensional structure 21. It has a gap (D) of 50 μm to 2,000 μm between it and the 3D structure 21 .

The coverage of the plurality of three-dimensional structures 21 of the special tactile structure module 2 on the surface 11 of the polymer resin film 1 is preferably 20% to 90%, more preferably 50% to 80%.

According to the above configuration, the special tactile structure module 2 of the film material 100 of the present embodiment can have the same tactile and tactile sensation as mesh fabric, but the visual effect of the grid-like visual pattern 12 is impaired. do not have.

It should be noted that the width W of the three-dimensional structure 21 is defined as the maximum width parallel to the surface 11 of the polymer resin film 1 in the three-dimensional structure 21 . The height H of the three-dimensional structure 21 is defined as the maximum height of the three-dimensional structure 21 perpendicular to the surface 11 of the polymer resin film 1 . The gap D is defined as the shortest distance between each three-dimensional structure 21 and an adjacent three-dimensional structure 21 . In each three-dimensional structure 21, the average particle size of the plurality of insoluble solid mixtures 212 is 20 μm to 150 μm, preferably 60 μm to 120 μm. Also, the content of the plurality of insoluble solid mixtures 212 in the three-dimensional structure 21 is 1 wt % to 10 wt %, preferably 3 wt % to 7 wt %. As such, the light transmittance of each three-dimensional structure 21 is 50% or less, preferably 70% or less.

When the particle size and/or content range of the plurality of insoluble solid mixtures 212 exceeds the upper limit of the above range, the visible light transmittance of the plurality of three-dimensional structures 21 becomes insufficient, and the plurality of three-dimensional structures 21 are polymerized. In some cases, it may not be possible to firmly adhere to the surface 11 of the resin film 1 .

Conversely, if the particle size and/or content range of the plurality of insoluble solid mixtures 212 is less than the lower limit value of the above range, the tactile feel of the mesh fabric of the plurality of three-dimensional structures 21 cannot be sufficiently obtained.

As shown in FIG. 3, in the cross-sectional view of the film material 100 of this embodiment, each three-dimensional structure 21 has a semicircular shape, but the present invention is not limited to this.

For example, each three-dimensional structure 21 may be formed in a shape such as a rectangular shape (shape shown in FIG. 10), a circular shape (shape shown in FIG. 11), or the like, which can provide the tactile sensation and feel of mesh fabric. good.

As shown in FIG. 12, the other surface 13 of the polymer resin film 1 of this embodiment remote from the special tactile structure module 2 can be used for bonding with fabric. As such, the structural strength of the film material 100 can be reinforced.

Among other things, the woven fabric has a plurality of warp yarns and a plurality of weft yarns (not shown in the drawing) interlaced with each other, or the woven fabric is made of, for example, polyester fibres, polyamide fibres, polypropylene fibres, acrylic fibres, or It may also be an elastic fiber (not shown in the drawing).
[Second embodiment]

Please refer to FIG. FIG. 13 shows a second embodiment according to the invention. This embodiment is substantially similar to the first embodiment described above, and the difference between them is that the film material 100 ′ of this embodiment does not have the grid-like visual pattern 12 .

Specifically, the film material 100′ of this embodiment includes a polymer resin film 1 and a special tactile structure module 2. As shown in FIG. The special tactile structure module 2 includes a plurality of 3D structures 21 . A plurality of three-dimensional structures 21 are arranged on one surface 11 of the polymer resin film 1 at intervals. Among other things, each configuration of the three-dimensional structure 21 includes a polymeric resin material 211 and a plurality of insoluble solid mixtures 212 dispersed in the polymeric resin material 211 . At least some of the insoluble solid mixtures 212 in the plurality of insoluble solid mixtures 212 are located on the surface layer of the three-dimensional structure 21 and are partially exposed to the external environment to be touched by the user.
[Third Embodiment]

A third embodiment according to the present invention provides a method (not shown) for manufacturing a membrane material. The manufacturing method of the present embodiment describes the details of the manufacturing method of the film material 100 of the first embodiment, but the manufacturing method of the film material 100 is not limited to the manufacturing method of the present embodiment.

In step S120, an ink material is printed on one surface of the polymer resin film 1 according to a predetermined pattern, and a liquid component (for example, water) is evaporated from the ink material, thereby forming an image on the surface 11 of the polymer resin film 1. A grid-like visual pattern 12 is formed.

The liquid component can be evaporated by baking at a high temperature (eg, 80° C. to 180° C.).

A step S130 forms a plurality of liquid glues on the surface 11 of the polymer resin film 1 .

The plurality of liquid pastes can be formed by, for example, an imitation mesh processing method, a printing roller transfer method, or the like, but the present invention is not limited thereto.

A plurality of liquid pastes are formed on the surface 11 of the polymer resin film 1 at intervals from each other, and in each liquid paste configuration, a polymer resin material 211 and a plurality of insoluble substances dispersed in the polymer resin material 211 are formed. Contains solid mixture 212 .

A step S140 forms a plurality of three-dimensional structures 21 adhered to the surface 11 of the polymer resin film 1 by evaporating a liquid component (for example, water) from the plurality of liquid pastes, Moreover, the plurality of three-dimensional structures 21 partially cover the grid-like visual pattern 12 .

By evaporating the liquid component by baking at a high temperature (80° C. to 180° C., for example), the polymer resin material 211 of the plurality of liquid pastes may be cured. During the curing process, a plurality of liquid glues are formed as a plurality of three-dimensional structures 21 adhered to the surface 11 of the polymer resin film 1, respectively.

Since all of the plurality of three-dimensional structures 21 have visible light transmittance, the grid-like visual pattern 12 on the surface 11 of the polymer resin film 1 is transmitted through the plurality of three-dimensional structures 21 and the polymer resin film 1 becomes visible on one side of the surface 11 of the .
[Beneficial effects of the embodiment]

One of the beneficial effects of the present invention is that the film material having a special tactile structure and the method for producing the same provided by the present invention have the following advantages: a plurality of insoluble solid mixtures dispersed in a resin material, wherein at least a portion of the insoluble solid mixtures in the plurality of insoluble solid mixtures is located on the surface layer of the three-dimensional structure and is touched by a user are partially exposed to the external environment for this reason.", and "Since each of the plurality of three-dimensional structures has visible light transmittance, the grid-like visual pattern on the surface of the polymer resin film is , and can be seen on the surface of the polymer resin film through the plurality of three-dimensional structures.”, The visual effect and sufficient tactile effect of the mesh cloth can be achieved in a thin and light state.
