DESCRIPTION OF THE EMBODIMENTS

[0024] In the present specification, for clarity, the size and proportion of layers and areas in the figures may be exaggerated. In addition, the number of dispensing in the dispensing layer or the dispensing structure shown is only for illustrative purposes, and the invention is not limited thereto, and adjustments may be made according to actual operating conditions.

[0025] FIG. 2 is a diagram of a composite material structure according to an embodiment of the invention.

[0026] Please refer to FIG. 2, the composite material structure includes a first cloth layer 20a, a second cloth layer 20b, a breathable thermoplastic material layer 28, and a lining cloth layer 26. In more detail, the breathable thermoplastic material layer 28 and the lining cloth layer 26 are both located between the first cloth layer 20a and the second cloth layer 20b. The breathable thermoplastic material layer 28 is disposed on the first cloth layer 20a to improve wearing comfort and breathability. The lining cloth layer 26 is composed of a base cloth 24 and a dispensing layer 22. The base cloth 24 is disposed on the second cloth layer 20b via the dispensing layer 22. Therefore, not only may the dispensing layer 22 improve the wearing comfort and breathability, compared to the thermoplastic film used in the existing structure, the base cloth 24 of the lining cloth layer 26 is less sensitive to heat, and therefore elasticity is not affected by a high-temperature process.

[0027] In the present embodiment, the breathable thermoplastic material layer 28 may include a dispensing structure (as shown in FIG. 2) or a mesh made of a thermoplastic material, wherein the thermoplastic material may include a copolymer or a blend of polyethersulfone (PES), polyamide (PA), thermoplastic polyurethane elastomer (TPU), polyethylene (PE), polymethyl methacrylate (PMMA), or a combination thereof, but the invention is not limited thereto. That is, even though the breathable thermoplastic material layer 28 shown in FIG. 2 has a dispensing structure, other breathable thermoplastic materials or processes may also be used as appropriate. The material of the base cloth 24 may include a copolymer or a blend of thermoplastic polyurethane (TPU), polyethersulfone (PES), polyamide (PA), thermoplastic polyurethane elastomer (TPU), thermoplastic polyester elastomer (TPEE), or a combination thereof. However, the invention is not limited thereto. Other elastic cloths may be used as appropriate to control the elasticity of the composite structure of the invention, and base cloths 24 having different elasticities, stretch recovery rates, and size specifications may also be used to improve design flexibility.

[0028] In the present embodiment, the dispensing layer 22 and the breathable thermoplastic material layer 28 adopting a dispensing structure may be made by a dispensing process. For example, a polymer resin colloid may be coated on the first cloth layer 20a to form the breathable thermoplastic material layer 28 adopting a dispensing structure; a polymer resin colloid may be coated on the second cloth layer 20b to make the dispensing layer 22. The polymer resin colloid may include a copolymer or a blend of polyethersulfone (PES), polyamide (PA), thermoplastic polyurethane elastomer (TPU), polyethylene (PE), polymethyl methacrylate (PMMA), or a combination thereof. However, the invention is not limited thereto.

[0029] Based on the above, the composite material structure of the invention includes a lining cloth layer composed of a base cloth and a dispensing layer and a breathable thermoplastic material layer, and is particularly suitable for sportswear or personal clothing. Compared with the existing laminating structure using thermoplastic film, in the invention, the air permeability, comfort, and ductility of clothing may be improved via the gaps in the dispensing layer and the breathable thermoplastic material layer, and elasticity is not affected by a high-temperature process, and therefore elastic uniformity may be further improved. Moreover, in the invention, the elasticity of the composite structure of the invention may be adjusted via the selection of the base cloth in the lining cloth layer, and different composite material elasticities may also be created by using lining cloths having different elasticities. Therefore, more flexibility may be achieved in design.

[0030] Although the invention is disclosed as above by the embodiments, the embodiments are not intended to limit the invention. Any person skilled in the art may make some changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention shall be subject to what is defined in the claims.
