Multilayer breathable fabric structure

The novel is a multi-layer fabric structure, in particular, a multi-layer breathable fabric structure having a three-dimensional shape and good air permeability.

General knee pads, ankle guards, elbow guards and other protective gear can provide support to reduce the load on muscles, ligaments and bones, thus avoiding joint and ligament injuries. Wherein, in the manufacture of the foregoing protective gear, a structure made of a foamed material is usually added between the two pieces of cloth, and the structure is further improved in addition to reinforcing the structural strength to overcome the problem of insufficient strength of the cloth. Can be used to absorb impact forces for protection purposes. However, since the structure made of the foamed material described above is not permeable to air, when the user wears the aforementioned protector for a while, it tends to be sultry and uncomfortable, thereby causing skin diseases.

Although some practitioners have several perforated vent holes in the structure, it is expected that the user's hot air and moisture can be discharged through these vent holes. However, in practice, such a structure has only a chance of venting and dissipating heat on the skin surface corresponding to the venting hole, and most of the skin surface is still hot and airtight because it abuts against the cloth. Furthermore, the through holes will cause the structure The damage, which in turn leads to the disappearance of the elasticity and texture of the original cloth, has yet to be improved. In addition, although another foam can be vented by punching, the gas permeable effect is still limited.

In addition, there is currently a traditional multi-layer breathable fabric on the market. The structure is as shown in Figs. 1A and 1B. 1A is a cross-sectional view showing a conventional multi-layered gas permeable structure 100. Fig. 1B is a schematic view showing the bending of the multi-layered gas permeable structure 100 of Fig. 1A. The main structure is to bond the foam 120 between the bottom layer 110 and the surface layer 130 by means of an adhesive. Such a structure can provide a composite material that is simple and has a partial gas permeable function. However, since the foam used in such a composite material has poor gas permeability and low plasticity, and when it is bent or twisted, the underlayer 110 or the surface layer 130 may generate irregular depressions and deformation extrusion. When such a composite material is applied to the upper, the depression and the deformation extrusion directly cause the upper surface to protrude, which causes the user's foot to be uncomfortable when worn. In addition, the mutual extrusion of the bottom layer 110, the foam body 120 and the surface layer 130 may also indirectly affect the force generated by the wearer during exercise, and in severe cases may cause blisters or injuries due to the squeeze.

As can be seen from the above, there is currently a lack of stereoscopic on the market. The permeable, breathable fabric structure with good sensibility, good air permeability, high plasticity, and even tight bending can maintain a close-fitting state, so the relevant companies are seeking solutions.

Therefore, the present invention provides a multi-layer breathable fabric structure, The bottom layer and the surface layer are heat-bonded by an adhesive, and a fabric body is sandwiched between the bottom layer and the surface layer, so that the surface layer can be three-dimensional. In addition, the bottom layer, the surface layer and the fabric body are all breathable materials, and have good gas permeability and moisture discharge property. In addition, by means of thermocompression bonding, not only can the bottom layer, the fabric body and the surface layer be closely adhered to each other, but also the multi-layer breathable fabric structure can avoid irregular distortion when bent.

The adhesive is applied to another area of the top surface, the two sides, the bottom surface, and the upper surface. The surface layer is adhesively bonded to the top surface, the two side surfaces, the bottom surface and the other portion of the upper surface by heat-pressing, so that the surface layer has a concave-convex shape.

Thereby, the novel multi-layer breathable fabric structure is adhered through The agent is heat-pressed to the bottom layer and the surface layer, and a plurality of fabric bodies are sandwiched between the bottom layer and the surface layer, so that the surface layer can have a three-dimensional effect.

Hereinafter, a plurality of embodiments of the present invention will be described with reference to the drawings. For the sake of clarity, many practical details will be explained in the following description. However, it should be understood that these practical details are not intended to limit the novel. That is to say, in some embodiments of the present invention, these practical details are not necessary. In addition, some of the conventional structures and elements are illustrated in the drawings in a simplified schematic manner, and the repeated elements may be represented by the same reference numerals.

Please refer to Figure 2 and Figure 3 together. 2 is a perspective view showing a multi-layer breathable fabric structure 200 according to an embodiment of the present invention. Figure 3 is a cross-sectional view showing the multi-layer breathable fabric structure 200 of Figure 2. As shown, the multi-layer breathable fabric structure 200 can be used on the upper of a shoe, and the multi-layer breathable fabric structure 200 includes a bottom layer 210, a plurality of fabric bodies 220, a skin layer 230, and an adhesive 240.

The bottom layer 210 has an upper surface 212. The material of the bottom layer 210 may be non-woven fabric, cotton, hemp, polyester fiber or elastic fiber. Further, the underlayer 210 has a bottom layer thickness T1, and the bottom layer thickness T1 is greater than or equal to 0.1 mm and less than or equal to 4 mm. The preferred embodiment of the present invention ranges from 0.5 to 1 mm because a smaller underlayer thickness T1 increases the gas permeable effect and reduces manufacturing costs. Of course, the thickness T1 of the bottom layer still needs to be above the lower limit to ensure that the structure of the bottom layer 210 has a certain tension and is not easy to loose. This lower limit is 0.1 mm.

The fabric body 220 includes a top surface 222 and two side surfaces 224a. 224b and a bottom surface 226. The bottom surface 226 is connected to the upper surface 212 of the bottom layer 210 and covers an area A1 of the upper surface 212. If the number of the fabric bodies 220 is larger, the area A1 covering the upper surface 212 is wider. Furthermore, the side surface 224a of any one of the fabric bodies 220 and the side surface 224b of the adjacent and corresponding other fabric body 220 have a spacing D, which may be greater than or equal to 3 mm and less than or equal to 10 mm. It depends on the three-dimensional shape made by the manufacturer. In order to effectively increase the surface area of the structure, the present invention is provided with a certain number of fabric bodies 220 per unit area to increase the unit density of the distribution of the fabric body 220. In addition, the material of the fabric body 220 may be non-woven fabric, cotton or synthetic fiber. The top surface 222 of the fabric body 220 may be circular, elliptical, triangular, rectangular, hexagonal, octagonal, curved or other polygonal shape, and the shape of the top surface 222 and the shape of the bottom surface 226 may be the same or different. Further, the fabric body 220 has a fabric thickness T2 which is equal to the height of the side faces 224a, 224b which is greater than or equal to 1 mm and less than or equal to 8 mm. The fabric thickness T2 of the fabric body 220 and the uneven surface of the bottom layer 210 or the surface layer 230 formed by the spacing D2 affect the degree of flexibility of the structure itself and the stereoscopic perception of the user (wearer) visually. If the thickness of the fabric T2 is thicker, the degree of flexibility of the structure is lower, and the stereoscopic effect of the wearer's vision is better. Of course, the fabric body 220 can be elongated and interlaced with each other, each fabric body 220 having a fabric width and a fabric length. Wherein the length of the fabric may be greater than or equal to 1 mm and less than or equal to 10 mm, and the length of the fabric is greater than the width of the fabric. Of course, a plurality of fabric bodies 220 can be integrally formed, or Set separately. Furthermore, the sides 224a, 224b of the fabric body 220 intersect the upper surface 212 at a first angle θ1 and the sides 224a, 224b intersect the top surface 222 at a second angle θ2. The first angle θ 1 may be greater than or equal to 20 degrees and less than or equal to 90 degrees, and the second angle θ 2 may be greater than or equal to 90 degrees and less than or equal to 160 degrees. When the first angle θ 1 is equal to the second angle θ 2 and both are 90 degrees, the fabric body 220 has a vertical columnar body and the shape of the top surface 222 is the same as the shape of the bottom surface 226, and the top surface 222 of the fabric body 220 The area is equal to the area of the bottom surface 226. It is also worth mentioning that the fabric density of the fabric body 220 and the width of the fabric yarn can be determined by the manufacturer. If the fabric body 220 has a water chest angle, a sharp corner or a right angle, the fabric density can be adjusted to be larger, so that the bottom layer 210 or the surface layer 230 can perfectly exhibit the shape of a water chest, a sharp corner or a right angle when it is closely adhered to the fabric body 220. If the fabric density is too small, the fabric body 220 will deform the shape of the fabric body 220 when subjected to an external force, and the stereoscopic effect of the original shape cannot be maintained.

The surface layer 230 is closely adhered to the fabric body by the adhesive 240 220. The surface layer 230 may be made of non-woven fabric, cotton, hemp, polyester fiber or elastic fiber. Further, the surface layer 230 has a surface layer thickness T3 which is greater than or equal to 0.1 mm and less than or equal to 4 mm. In particular, the thinner skin thickness T3 combined with the thicker fabric thickness T2 can highlight the embossing stereoscopic effect of the fabric body 220.

Adhesive 240 can be tape, glue or resin. Adhesive The thickness of 240 is relatively thin, and the adhesive 240 is uniformly applied to the top surface 222 of the fabric body 220, the two side surfaces 224a, 224b, the bottom surface 226, and another area A2 of the upper surface 212. The novel multi-layer breathable fabric structure 200 The structure is heat-pressed through a mold of a corresponding shape, so that the adhesive 240 fills the gap between the bottom layer 210, the fabric body 220, and the surface layer 230 to be closely adhered. The surface layer 230 is thermally bonded to the top surface 222, the two side surfaces 224a and 224b, and the other area A2 of the upper surface 212 by the adhesive 240, so that the surface layer 230 has an uneven shape.

Figure 4 is a diagram showing a multi-layer breathable weave of another embodiment of the present invention. A cross-sectional view of the object structure 200. The shape of the fabric body 220 is curved, and the first angle θ 1 is 45 degrees. The arc shape of the fabric body 220 has different visual layering and stereoscopic effect than the multi-layer breathable fabric structure 200 of FIG. .

Figure 5A is a schematic view showing the flow of surface gas in Figure 3 Figure. Figure 5B is a schematic view showing the bending of the multi-layer breathable fabric structure 200 of Figure 5A. Referring to FIGS. 1A and 1B, it can be seen from the drawings that the conventional two-dimensional multi-layer gas permeable structure 100 and the three-dimensional multi-layer breathable fabric structure 200 of the present invention have significant differences. In the conventional multi-layer gas permeable structure 100, in addition to the poor gas permeability of the foam 120 and low plasticity, the hollow gap between the bottom layer 110 and the surface layer 130 often causes irregular depression and extrusion deformation; The three-dimensional multi-layer breathable fabric structure 200 can increase the wind receiving area during the movement, not only can increase the air intake amount to increase the air permeability and the moisture venting property, but also reduce the moisture remaining in the hollow gap, and at the same time take into consideration the sports performance and comfort. Further, when the multi-layered breathable fabric structure 200 is bent or twisted by an external force, the bottom layer 210, the fabric body 220, and the surface layer 230 are still closely adhered to each other without a phenomenon of depression or deformation. Therefore, the multi-layer breathable fabric structure 200 is well suited for use on uppers.

Figure 6 is a diagram showing an embodiment of the present invention applied to an upper schematic diagram. When the multi-layer breathable fabric structure 200 is combined with the shoe, since the shoe itself has a certain degree of curvature, the multi-layer breathable fabric structure 200 can exhibit a better three-dimensional feeling on the upper. In addition, the shape of the fabric body 220 can be selected by the manufacturer, and the fabric body 220 with the curvature of the upper and the fabric thickness T2 of different fabrics can create a three-dimensional effect of various different surface layers.

As can be seen from the above embodiments, the present invention has the following advantages: First, the novel multi-layer breathable fabric structure can be applied to the upper of the shoe, and the bottom layer and the surface layer are bonded by heat pressing with an adhesive, and the fabric body is sandwiched between the bottom layer and the surface layer, so that the surface layer can be three-dimensional. Second, the bottom layer, the surface layer and the fabric body are all breathable materials, and the multi-layer breathable fabric structure formed by the three bonding has good gas permeability and moisture discharge property. Thirdly, by means of thermocompression bonding, not only the bottom layer, the fabric body and the surface layer can be closely adhered to each other, but also the multi-layer breathable fabric structure can avoid irregular distortion when bent.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Any one skilled in the art can make various changes and retouchings without departing from the spirit and scope of the present invention. The scope is subject to the definition of the scope of the patent application attached.
