DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a sports aid, and more particularly to a method of manufacturing a yoga mat. [Prior Art] As shown in FIG. 1 , a conventional method for manufacturing a yoga mat is to stack a first cushion layer 1 and a second cushion layer 2 made of an elastic foam material, and then put a hot press. The mold 3 is heat bonded. This type of yoga mat is composed only of the first and second mats 丨'2 which are attached to each other, and the tensile strength is insufficient. Furthermore, when the first and second layers 1 and 2 are stacked and placed in the hot stamping die 3, the air bubbles 101 are often coated between the first and second layers 1 and 2, when After the yoga mat, the surface of the yoga mat will be embossed due to the bubble of 1〇1, resulting in defective products. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method of manufacturing a yoga mat which can produce better tensile strength and avoid bubble generation without requiring gumming. The method for manufacturing the yoga mat of the present invention comprises the following steps: (A) preparing a first cushion layer, a second cushion layer and an intermediate layer, wherein the first cushion layer is a foamed thermoplastic elastic material, and The first density 塾 layer is also a foamed thermoplastic elastic material, the middle one, and has a second density,

The first and second mat layers 1 and 20 are made of a foamed thermoplastic elastic material ( TPE), and may be thermoplastic polyurethane elastomer (TPU), thermoplastic rubber (TPR), polyolefin elastomer (TP0), nitrile butadiene rubber (NBR), methyl acrylate Methacrylate Butadiene Rubber (MBR), Styrene Butadiene Rubber (SBR) and each have a first and second density, and the intermediate layer 30 is a thermoplastic elastomer (TPE). And having a third density greater than the first and second densities. Specifically, the intermediate layer 30 is a non-foamed thermoplastic elastic material. Since the structure is dense, the density is high and the tensile strength is better. In addition, in 200916156, the first and second layers 10, 20 are respectively pierced such that the first and second layers 10, 20 have an inner side 11, 21, and an outer side opposite to the inner side η, 21 Side faces 12, 22 and a plurality of perforations 13, 23 extending through the inner and outer Φs 11, 21, 12, 22, the intermediate layer 30 also having a first side 31 opposite the first inner side U and a The first side: the second side step of the 31-phase sigh and the inner side of the second cushion layer 2 is as shown in FIG. 3, and the intermediate layer 3G is sandwiched between the first layer and the first layer. Between 20 and 20, the perforations 13, 23 of the first and second layers 10, 20 can be connected to the intermediate layer 3, and the first and second layers 1 and 3 are stacked and then placed in a heat. Mould 2〇〇 is heat-bonded and hot-pressed at the same time as the pumping true heat (hot pressing temperature 9〇~12〇°c, hot pressing time 3~5 seconds), and can be along the perforations 13 and 23 by vacuuming. The first and second mat layers are removed, and the air bubbles between the intermediate layer 3G and the intermediate layer 3G are removed, and the first and second layers 1(), 2〇 and the intermediate layer 30 are heat-bonded and consolidated into one half of the finished product. At the same time, the first and second cushions 10, 20 surface formation of the texture. Step 3: As shown in Figure 4, the hot-pressed semi-finished product 1〇〇 is cut to obtain a yoga mat with a predetermined shape and size specifications, 1 (see Figure 5 Therefore, the first and second mat layers 10 and 2 are stacked and placed in the middle of the β-hot stamping die 2 to be thermally bonded, so that the first and second mat layers 10 can be made. 20 can be combined with the intermediate layer 3〇 without applying an adhesive, and has better tensile strength, and does not need to apply adhesive, the process is relatively simple, and the overall cost and waste recycling are relatively easy. And using the 200916156 one layer 10, 20 to perform the puncture operation in advance to form the perforations 13, 23, when the heat bonding is performed, the first and second bedding layers and the middle door layer 30 may be eliminated. The bubble 'can avoid producing defective products. The second embodiment is substantially the same as the manufacturing steps of the first embodiment' and includes the following steps: Step - ': As shown in FIG. 6, a first mat 10 is prepared in advance. a first layer 20, an intermediate layer 30 and a fabric layer 40. The first layer 1 0. The second pad layer 20 and the intermediate layer 3〇 are all configured in the same manner as the first embodiment, and the fabric layer 40 is a mesh cloth. Step 2: As shown in FIG. 7 , the fabric layer 4 is sandwiched between Between the intermediate layer 3〇 and the second underlayer 20, the first and second underlayers 10 and 20 are stacked on the intermediate layer 30 and the fabric layer 4, and placed in a hot pressing die 2 to perform heat. Laminating and hot pressing, and causing the intermediate layer 3〇 and the portion of the second layer 2〇 to be softened and then infiltrated into the fabric layer 4 to form a half finished product. Step 2: 8 shows that the semi-finished product can be cut to obtain a yoga mat having a predetermined shape and size. Therefore, the yoga mat 3 made by the second embodiment of the present invention can further strengthen the tensile strength by using the fabric layer 40, and utilizes the intermediate layer 3 and the partial material of the second cushion layer 20. After being softened by heat, it will penetrate into the fabric layer 40, and the consolidation property of the intermediate layer 3〇 and the second underlayer 2〇 can be improved. However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention, All of them are still within the scope of the invention patent 200916156.
