[0035] Please refer to Figure 1 and Figure 2 ,in Figure 1 FIG. 1 is a schematic diagram of a composite fabric 100 according to an embodiment of the present invention. Figure 2 Draw according to Figure 1 A side cross-sectional view of a composite fabric 100 is shown. Figure 1 and Figure 2 As shown, the composite fabric 100 includes a fabric structure 110 and a thermoplastic structure 120. The fabric structure 110 includes at least an upper layer 111 and a lower layer 113. The thermoplastic structure 120 includes a moisture curing hot melt adhesive layer 121 (indicated at Figure 3A ), wherein the moisture curing hot melt adhesive layer 121 is fixed to the upper layer 111 of the fabric structure 110. A portion of the thermoplastic structure 120 and a portion of the composite fabric 100 form a plurality of laminations 140, and another portion of the thermoplastic structure 120 and another portion of the composite fabric 100 form a plurality of airbag portions 130, each airbag portion 130 being higher than each lamination portion 140.

[0036] The fabric structure 110 and the thermoplastic structure 120 of the composite fabric 100 are formed by an ultrasonic die 150 (indicated at Figure 3B) are pressed together for processing, so that the area pressed by the ultrasonic mold 150 is combined to form a pressing part 140, and after multiple processing, the area not pressed by the ultrasonic mold 150 forms an airbag part 130, which is higher than the pressing part 140. The surface of the composite fabric 100 formed by the thermoplastic structure 120 can increase the surface friction of the composite fabric 100, so that the composite fabric 100 can be applied to ball equipment, such as the surface of football, tennis, and basketball, and when the composite fabric 100 is applied to clothing or footwear, the airbag part 130 formed by the thermoplastic structure 120 and the fabric structure 110 can reduce the impact force received by the user during exercise, and there is no need to set an additional elastic material in the composite fabric 100, thereby improving the protection without reducing flexibility. In this way, the structure of the composite fabric 100 can be simplified and have high friction and high protection. The structural details of the composite fabric 100 will be described in detail below.

[0037] The fabric structure 110 may further include a middle layer 112 located between the upper layer 111 and the lower layer 113, the upper layer 111 includes an open-pore fiber structure body, the middle layer 112 may include a monofilament mesh body, and the lower layer 113 includes a quick-drying fiber body. Specifically, the denier of the open-pore fiber structure body of the upper layer 111 may be between 50D and 300D, the denier of the monofilament mesh body of the middle layer 112 may be between 20D and 100D, and the denier of the quick-drying fiber body of the lower layer 113 may be between 200D and 300D, and is made of velvet yarn, but the present invention is not limited thereto. Through the composition of the upper layer 111, the middle layer 112 and the lower layer 113, the fabric structure 110 can form a multi-layer mesh structure with multiple pores. When the upper layer 111, the middle layer 112 and the lower layer 113 are not pressed together, it means that the multi-layer mesh structure is not compacted or fused and the pores are reserved for air to fill in to form an airbag structure. When the composite fabric 100 is applied to clothing, the lower layer 113 can improve the comfort when it comes into contact with the user's skin, and when the user exercises, it can absorb moisture and discharge heat through the pores to achieve the effect of moisture absorption and quick drying; when the composite fabric 100 is applied to the bottom lining of shoes, it can provide a non-slip effect on the feet. In other embodiments, the fabric structure can be a mesh structure with four or five layers, and the present invention is not limited to this. In addition, the thermoplastic structure 120 can have a transparency of 40%-80%. This can increase the perspective of the composite fabric 100.

[0038] Please refer to Figure 3A and Figure 3B ,in Figure 3A Draw according to Figure 2 A schematic diagram of a thermoplastic structure 120 being fixed to a fabric structure 110 by a moisture-curable hot melt adhesive layer 121, Figure 3B Draw according to Figure 3ASchematic diagram of the thermoplastic structure 120 and the fabric structure 110 being resonated by an ultrasonic mold 150. Figure 3A As shown, the thermoplastic structure 120 may further include a composite resin layer 122, which is disposed on the moisture-curable hot melt adhesive layer 121. The moisture-curable hot melt adhesive layer 121 may include a moisture-hardening polyurethane hot melt adhesive (Polyurethane Reactive; PUR) body, and the thickness of the moisture-curable hot melt adhesive layer 121 may be between 0.2 mm and 0.6 mm, and it functions as a bridging agent. The composite resin layer 122 may include a polyurethane (PolyUrethane; PU) body, and the thickness of the composite resin layer 122 may be between 0.2 mm and 0.4 mm, so that the thickness of the thermoplastic structure 120 is between 0.4 mm and 1.0 mm. Figure 1 Before the fabric structure 110 and the thermoplastic structure 120 in the embodiment are formed into the composite fabric 100, the thermoplastic structure 120 is first connected to the fabric structure 110 by a moisture curing hot melt adhesive layer 121 through a moisture curing reaction and fixed thereto. Figure 3B As shown, after the thermoplastic structure 120 is fixed to the fabric structure 110, the ultrasonic mold 150 is pressed downward from the top of the thermoplastic structure 120 to press the thermoplastic structure 120 with the upper layer 111, the middle layer 112 and the lower layer 113, and the areas where the thermoplastic structure 120 and the fabric structure 110 contact with the ultrasonic mold 150 are fused through ultrasonic resonance, so that a part of the thermoplastic structure 120 is fused with a part of the upper layer 111, the middle layer 112 and the lower layer 113 of the fabric structure 110 to form a Figure 2 The lamination portion 140 shown in the figure makes the upper layer 111, the middle layer 112 and the lower layer 113 in the lamination portion 140 have zero pores or very few pores. And the thermoplastic structure 120 and the upper layer 111, the middle layer 112 and the lower layer 113 of the fabric structure 110 that are not in contact with the ultrasonic mold 150 form a region as shown in the figure. Figure 2 Please refer to the airbag portion 130 shown in FIG. Figure 1 The ultrasonic mold 150 may be a hexagonal mold, for example, a metal roller is used to perform ultrasonic molecular resonance, so that the pressing portion 140 formed by ultrasonic resonance is a hexagon and surrounds the airbag portion 130. In other embodiments, the ultrasonic mold may be a triangular, polygonal or irregularly shaped mold, and a pressing portion of different shapes may be formed according to requirements to achieve an aesthetic effect, but the present invention is not limited thereto.

Figure 1The composite fabric 100 of the embodiment is described, but the present invention is not limited thereto. The composite fabric forming method S100 includes a fabric forming step S110 and an ultrasonic resonance step S120. In the fabric forming step S110, a fabric structure 110 includes at least an upper layer 111 and a lower layer 113, and a thermoplastic structure 120 is fixed to the upper layer 111 of the fabric structure 110 by a moisture curing reaction. In the ultrasonic resonance step S120, the thermoplastic structure 120 and the fabric structure 110 are pressed together by an ultrasonic mold 150 to form a composite fabric 100, so that a part of the thermoplastic structure 120 and a part of the fabric structure 110 are fused by ultrasonic resonance to form a plurality of pressed parts 140, and another part of the thermoplastic structure 120 and another part of the fabric structure 110 are not fused to form a plurality of airbag parts 130, and each airbag part 130 is higher than the pressed part 140.

[0040] Thus, by means of ultrasonic resonance, a composite fabric 100 having an airbag portion 130 can be formed, which can reduce the impact of external force, and the composite fabric 100 has a high surface friction through the thermoplastic structure 120, so that the composite fabric 100 can be applied to balls, shoes or clothes to provide users with sufficient protection. Other details of the composite fabric forming method S100 are similar to Figures 1 to 3B The embodiments are not described in detail.

[0041] In summary, the present invention provides a composite fabric and a method for forming a composite fabric, which have the following advantages: first, an airbag portion that provides protection can be formed through ultrasonic mold lamination; second, the lower layer containing a quick-drying fiber body can improve the comfort of the user contacting the composite fabric; and third, composite fabrics with different appearances can be formed according to needs through ultrasonic molds of different shapes.
