[0002] With the improvement of people's health consciousness, as a popular fitness way, yoga makes yoga mat become the common equipment for people's daily fitness. The yoga mat on the market has various materials, mainly including rubber, PVC (polyvinyl chloride) and TPE (thermoplastic elastomer) and the like.

[0003] Although the rubber yoga mat has good skid resistance and resilience, it is heavy in quality, inconvenient to carry, and may produce a pungent smell in the production and use process, and some rubber raw materials also have the problem of non-degradability, which causes great pressure on the environment.

[0004] The PVC yoga mat has relatively low cost and rich colors, but it contains a large amount of plasticizer and chlorine element. The plasticizer is easy to volatilize in the use process, which not only affects human health, but also makes the yoga mat aging and brittle; the chlorine element produces toxic and harmful gases when burning, which causes serious pollution to the environment and does not meet the current environmental protection concept.

[0005] The TPE yoga mat is a relatively environmentally friendly material, which has the characteristics of non-toxic and degradable, but its skid resistance and durability are not good in some high-intensity use scenarios.

[0006] It can be seen that the prior art still needs to be improved and improved. UTILITY MODEL CONTENT

[0020] The utility model provides a kind of environmental protection type composite yoga mat, to make the purpose, technical scheme and effect of the utility model more clear, definite, the following referring to drawing and taking example to further detail the utility model of example.It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the protection scope of the utility model.

[0021] Please refer to Figure 1 The utility model provides a kind of environmental protection type composite yoga mat, including TPU foamed surface layer 1, TPE intermediate buffer foamed layer 2 and TPE foamed bottom layer 3 sequentially from top to bottom;The density of TPE intermediate buffer foamed layer 2 is less than the density of TPE foamed bottom layer 3.

[0022] TPU is a more environmentally friendly material, does not contain harmful substances, in line with relevant environmental standards, compared with some traditional rubber or PVC yoga mat, TPU foaming yoga mat is safer, more friendly to the human body and the environment. In addition, the TPU foaming surface layer 1 has good elasticity, wear resistance, aging resistance and low temperature toughness and other advantages, its excellent elasticity, soft touch can provide comfortable support and cushioning for yoga practitioners, reduce joint pressure; In addition, its good wear resistance ensures that the yoga mat is not easy to damage in the long-term use process. The price of TPU is higher than that of TPE, so the contract with the same non-toxic and odorless, degradable TPE can reduce the manufacturing cost of the yoga mat.

[0023] In this embodiment, the TPE is divided into an intermediate buffer layer and a bottom layer, and the density of the intermediate buffer layer (about 0.3-0.5 g / cm 3 ) is less than the density of the bottom layer (about 0.8-1.2 g / cm 3 ), so as to meet the high rebound buffer performance of the intermediate layer, and enhance the density of the bottom layer to improve the grip, thereby preventing the yoga mat from moving during use. That is, the pore size of the foam can be changed by controlling the high foaming rate (60-80%) of the intermediate layer and the low foaming rate (20-40%) of the bottom layer during foaming.

[0024] The composite of the surface layer, the intermediate layer and the bottom layer can be achieved by hot melt bonding (by controlling the temperature and pressure during hot pressing) to make the molecular chains of the adjacent layer material surfaces entangle with each other, thereby avoiding delamination.

[0025] Specifically, the TPU foaming surface layer 1, the TPE intermediate buffer foaming layer 2, and the TPE foaming bottom layer 3 are all physically foamed. Physical foaming is to introduce gas such as carbon dioxide, nitrogen and the like into TPU and TPE, and then expand the gas to form pores by controlling pressure and temperature and the like.

[0026] The yoga mat described above further improves the physical properties such as scratch resistance, impact resistance and elasticity of the yoga mat by compounding the TPU foaming surface layer 1 on the traditional TPE yoga mat; and limits the use of TPE intermediate buffer foaming layer 2 and TPE foaming bottom layer 3 formed by different densities, so as to meet the high rebound buffer performance of the intermediate layer, and enhance the density of the bottom layer to improve the grip, thereby preventing the yoga mat from moving during use, while also reducing the manufacturing cost.

[0027] Please refer to Figure 1In some embodiments, the surface of the TPU foamed surface layer 1 is engraved with a linear texture layer and / or a pattern texture layer 11. Specifically, the upper surface of the TPU foamed surface layer 1 can be engraved with, for example, lines, patterns, logos, etc. by laser engraving, which not only increases the anti-slip performance of the TPU surface layer, but also plays a decorative role for the yoga mat, thereby improving the aesthetic appearance of the yoga mat.

[0028] Referring to Figure 2 In some embodiments, the lower surface of the TPE foamed bottom layer 3 is provided with a plurality of anti-slip suction cups 4. The plurality of micro anti-slip suction cups 4 are provided to improve the grip performance of the TPE foamed bottom layer 3.

[0029] Referring to Figure 2 In some embodiments, each of the plurality of anti-slip suction cups 4 includes an embedded head 41 and a suction cup body 42 connected to the bottom of the embedded head 41, and the bottom of the suction cup body 42 is formed with an inwardly recessed cavity 43. A plurality of slot holes 31 are formed on the TPE foamed bottom layer 3, which are adapted to the shape of the embedded head 41, and the embedded head 41 is located in the corresponding slot hole 31. The formation of the slot hole 31 can provide an installation position for the embedded head 41, and the embedded head 41 is deeply embedded in the interior of the TPE bottom layer, which can further improve the connection stability of the anti-slip suction cup 4 and the TPE bottom layer. When the user uses the yoga mat for practice, the air in the inwardly recessed cavity 43 of the suction cup body 42 is squeezed out, forming a local vacuum / negative pressure adsorption, thereby improving the grip of the yoga mat. The provision of the above-mentioned anti-slip suction cup 4 enables the yoga mat to be adapted to the use of a larger humidity ground, i.e. a venue with more sweat or a humid weather.

[0030] Referring to Figure 2 In some embodiments, the embedded head 41 and the suction cup body 42 are integrally formed. Specifically, the anti-slip suction cup is also made of TPE material, and the integrally formed anti-slip suction cup 4 structure has higher integrity and seamless connection, which can adapt to the repeated extrusion deformation during yoga practice, thereby ensuring the durability of the yoga mat.

[0031] Referring to Figure 2 In some embodiments, a plurality of anti-slip protrusions 44 are arranged on the cavity wall of the cavity 43. The plurality of anti-slip protrusions 44 can make multi-point contact with the ground, thereby increasing the effective friction area and further improving the anti-slip coefficient.
