Description

DETAILED DESCRIPTION OF THE INVENTION

(1) The technical features of the present disclosure will be more fully understood from the following description and a preferred embodiment.

(2) A manufacturing method of exercise mat according to a preferred embodiment of the present disclosure comprises the steps as follows.

(3) A mixture is provided by mixing 15 wt % to 60 wt % of a plant fiber composite and 40 wt % to 85 wt % of a foamable material. Then, an appropriate foaming agent is introduced into the mixture. Finally, a foaming process is performed at a predetermined temperature to form a mat. The foaming process can be any one of continuous foaming, injection foaming, and in-mold foaming. The plant fiber composite includes a plant fiber raw material, a starch assistant, and a biopolymer additive containing a plant hormone, an enzyme, a biological vinegar, and lactic acid ester. The foamable material is one of polyvinylchloride (PVC) and natural rubber (NR). The foaming agent can be a foaming agent known in the art, such as azodicarbonamide (ADCA or referred to as AC foaming agent) and 4,4-oxydibenzenesulfonyl hydrazide (OBSH). The predetermined temperature varies depending on the kind of the foamable material, for example the temperature may be about 180 C. when the foamable material is PVC, or the temperature may be about 150 C. when the foamable material is NR.

(4) In the manufacturing method of the preferred embodiment, the plant fiber raw material is selected from the group consisting of straw, sugarcane residue, corncob, coconut shell, cereal husk, peanut shell, leaves, bamboo leaves, sawdust, bamboo stem dust, and a combination thereof. The starch assistant is selected from the group consisting of sweet potato powder, potato powder, corn powder, and a combination thereof.

(5) In the manufacturing method of the preferred embodiment, the plant fiber composite includes the plant fiber raw material, the starch assistant, and the biopolymer additive in a weight ratio of 6:1:3 or 7:1:2. The aforesaid weight ratios have been already disclosed in Taiwan Patent No. 1367234 and are not the primary technical features of the present disclosure, thus require no further description.

(6) In the manufacturing method of the preferred embodiment, the biopolymer additive includes the plant hormone, the enzyme, the biological vinegar, and the lactic acid ester in a weight ratio of 10:5:2:3. The aforesaid ratio has also been disclosed in Taiwan Patent No. 1367234 and thus requires no further description.

(7) In a first embodiment, the material composition includes 15 wt % of the plant fiber composite and 85 wt % of the foamable material.

(8) In a second embodiment, the material composition includes 30 wt % of the plant fiber composite and 70 wt % of the foamable material.

(9) In a third embodiment, the material composition includes 45 wt % of the plant fiber composite and 55 wt % of the foamable material.

(10) In a fourth embodiment, the material composition includes 60 wt % of the plant fiber composite and 40 wt % of the foamable material.

(11) The material compositions of examples 1 to 8 shown in the following Tables 1 and 2 were used to produce exercise mats through the manufacturing method of the present disclosure. Static and kinetic coefficients of friction of the exercise mats manufactured from examples 1 to 8 were determined by ASTM D1894-11 at a temperature of 232 C., a relative humidity of 502%, a velocity of 150 mm/min, and a force of 221.83 g on a wooden contact surface. The results are shown in Tables 1 and 2.

(12) TABLE-US-00001 TABLE 1 Plant Fiber Foamable Coefficient Coefficient Composite Material of Static of Kinetic Example (wt %) (PVC, wt %) Friction Friction 1 15 85 0.29 0.18 2 30 70 0.37 0.23 3 45 55 0.45 0.26 4 60 40 0.49 0.26

(13) It can be known from Table 1 that exercise mats manufactured from examples 1 to 4 possess different static and kinetic coefficients of friction. These exercise mats, therefore, provide different anti-slip effects when laid on the ground for exercise.

(14) TABLE-US-00002 TABLE 2 Plant Fiber Foamable Coefficient Coefficient Composite Material of Static of Kinetic Example (wt %) (PVC, wt %) Friction Friction 5 15% 85% 1.65 1.63 6 30% 70% 1.51 1.49 7 45% 55% 1.59 1.57 8 60% 40% 1.53 1.51

(15) It can be known from Table 2 that exercise mats manufactured from examples 5 to 8 possess different static and kinetic coefficients of friction. These exercise mats, therefore, provide different anti-slip effects when laid on the ground for exercise.

(16) Besides, by mixing the plant fiber composite with the foamable material, the intrinsic odor of the foamable material can be reduced. Accordingly, the exercise mat of the present disclosure significantly overcomes the odor issue. It can be expected that the higher the amount of the plant fiber composite, the better the deodorizing effect.

(17) As described above, because the present disclosure provides an exercise mat made by foaming a mixture of a plant fiber composite and a foamable material, the present disclosure is environmentally friendly, low odor, and recyclable.
