[0056] Combination Figure 2 , Figure 3 and Figure 4According to an embodiment of the present invention, in a fabric repetition area Q, the second column of warp yarns 2 is woven with the first row of weft yarns I, the second row of weft yarns II, and the third row of weft yarns III, forming a front warp float J on the front side of the elastic band, that is, exposing the second column of fine denier polyester warp yarns 2 on the front side of the elastic band, thereby forming the front warp float J of fine denier polyester, as shown below. Figure 2 and Figure 4 As shown.
[0057] The third warp yarn 3 is woven with the second weft yarn II, the third weft yarn III, and the fourth weft yarn IV, forming a front weft float W on the right side of the elastic band.

Figure 2 and Figure 4 As shown.
[0058] The third warp yarn 3 is woven with the second weft yarn II, the third weft yarn III, and the fourth weft yarn IV, forming the reverse warp float C on the reverse side of the elastic band.

Figure 3 and Figure 4 As shown.
[0059] The fourth warp yarn 4 is woven with the first weft yarn I, the third weft yarn III, and the fourth weft yarn IV, forming the front warp float J on the right side of the elastic band.

[0060] The fifth warp yarn 5 is woven with the first row of weft yarns I, the second row of weft yarns II, and the fourth row of weft yarns IV, forming a front weft float W on the right side of the elastic band. This means that the first row of weft yarns I, the second row of weft yarns II, and the fourth row of weft yarns IV of fine denier polyester are exposed on the right side of the elastic band, thus forming the front weft float W of fine denier polyester. Figure 2 and Figure 4 As shown.
[0061] The fifth warp yarn 5 is woven with the first weft yarn I, the second weft yarn II, and the fourth weft yarn IV, forming the reverse warp float C on the reverse side of the elastic band. This means that the fifth warp yarn 5 exposes the coarse denier polyester on the reverse side of the elastic band, thus forming the reverse warp float C of the coarse denier polyester. Figure 3 and Figure 4 As shown.
[0062] The sixth warp yarn (6) is woven with the first weft yarn (I), the second weft yarn (II), and the third weft yarn (III), forming the front warp float J on the right side of the elastic band. This means that the sixth warp yarn (6) of fine denier polyester is exposed on the right side of the elastic band, thus forming the front warp float J of fine denier polyester. Figure 2 and Figure 4 As shown.
[0063] The seventh warp yarn 7 is woven with the second weft yarn II, the third weft yarn III, and the fourth weft yarn IV, forming a front weft float W on the right side of the elastic band. This means that the second weft yarn II, the third weft yarn III, and the fourth weft yarn IV of fine denier polyester are exposed on the right side of the elastic band, thus forming the front weft float W of fine denier polyester. Figure 2 and Figure 4 As shown.
[0064] The seventh warp yarn 7 is woven with the second weft yarn II, the third weft yarn III, and the fourth weft yarn IV, forming the reverse warp float C on the reverse side of the elastic band. This means that the seventh warp yarn 7 exposes the coarse denier polyester on the reverse side of the elastic band, thus forming the reverse warp float C of the coarse denier polyester. Figure 3 and Figure 4 As shown.
[0065] The eighth warp yarn 8 is woven with the first weft yarn I, the third weft yarn III, and the fourth weft yarn IV, forming the front warp float J on the right side of the elastic band. This means that the eighth warp yarn 8, which exposes the fine denier polyester on the right side of the elastic band, forms the front warp float J of the fine denier polyester. Figure 2 and Figure 4 As shown.
[0066] The ninth warp yarn (9) is woven with the first weft yarn (I), the second weft yarn (II), and the fourth weft yarn (IV) to form a front weft float (W) on the right side of the elastic band. This means that the first weft yarn (I), the second weft yarn (II), and the fourth weft yarn (IV) of fine denier polyester are exposed on the right side of the elastic band, thus forming the front weft float (W) of fine denier polyester. Figure 2 and Figure 4 As shown.
[0067] The ninth warp yarn 9 is woven with the first weft yarn I, the second weft yarn II, and the fourth weft yarn IV, forming the reverse warp float C on the reverse side of the elastic band. This means that the ninth warp yarn 9 exposes the coarse denier polyester on the reverse side of the elastic band, thus forming the reverse warp float C of the coarse denier polyester. Figure 3 and Figure 4 As shown.
[0068] The first warp yarn 1 is woven with four rows of weft yarns (first row of weft yarn I, second row of weft yarn II, third row of weft yarn III and fourth row of weft yarn IV), and the first warp yarn 1 of the spandex-covered yarn provides elasticity for the elastic band.
[0069] The elastic band of this invention has a total of 36 warp and weft interlacing points. Among them, there are 12 fine denier polyester warp floats J and 12 fine denier polyester weft floats W on the front side of the elastic band (the first column of warp yarns 1 only provides elasticity to the elastic band and has no moisture-wicking function; the number of warp and weft interlacing points woven by the first column of warp yarns 1 and the four rows of weft yarns is not counted). The total number of fine denier polyester warp floats J and fine denier polyester weft floats W exposed on the front side of the elastic band is 24, accounting for 67% of the total 36 warp and weft interlacing points of the elastic band. That is, the area of the fine denier polyester warp floats J and fine denier polyester weft floats W accounts for 67% of the area of the front side of the elastic band.
[0070] There are 12 coarse denier polyester warp floats C on the reverse side of the elastic band, accounting for 33% of the total 36 warp and weft interlacing points of the elastic band. That is, the area of the coarse denier polyester warp floats C accounts for 33% of the area of the reverse side of the elastic band.
[0071] This invention uses warp float C on the reverse side of the coarse denier polyester fabric. Because the coarse denier polyester forms relatively large capillaries in the fabric, the liquid water in the capillaries generates a smaller additional pressure. Conversely, this invention uses warp float J on the front side of the fine denier polyester fabric and weft float W on the front side of the fine denier polyester fabric. Because the fine denier polyester forms relatively small capillaries in the fabric, the liquid water in the capillaries generates a larger additional pressure.
[0072] As a result, an additional pressure difference is formed at the interface between the front and back of the elastic band, creating a differential capillary effect. This allows the sweat produced by the human body to be quickly transported from the back of the elastic band to the front, where it evaporates and dries on the surface. The sweat is transported while the body is sweating, keeping the back of the elastic band dry. This keeps the body feeling dry and comfortable, without creating a sticky effect or affecting the body's motor functions.
[0073] The first warp yarn 1 is woven with four weft yarns (first weft yarn I, second weft yarn II, third weft yarn III, and fourth weft yarn IV). The first warp yarn 1 of the spandex-covered yarn provides elasticity to the elastic band and does not produce a one-way moisture-wicking effect.
[0074] According to an embodiment of the present invention, the fabric parameters of the elastic band with a single-layer structure having a one-way moisture-wicking function are as follows: warp density 78-82 threads / 10mm, weft density 20-22 threads / 10mm, and stretch ratio 1:2.2-2.4 (original length: maximum stretch length).
[0075] According to an embodiment of the present invention, a method for manufacturing a single-layer elastic band with unidirectional moisture-wicking function is provided, the method comprising:

[0077] Furthermore, the first warp yarn 1 uses one 840D spandex / maximum stretch ratio 2.6 / front-wrap 75D polyester / back-wrap 75D polyester spandex covered yarn, or one 1680D spandex / maximum stretch ratio 2.6 / front-wrap 150D polyester / back-wrap 150D polyester spandex covered yarn.

The fifth warp yarn 5 is woven with the first weft yarn I, the second weft yarn II, and the fourth weft yarn IV, forming the wrong-side warp float C on the reverse side of the elastic band.
[0086] The sixth warp yarn 6 is woven with the first weft yarn I, the second weft yarn II, and the third weft yarn III to form the front warp float J on the front side of the elastic band.
[0087] The seventh warp yarn 7 is woven with the second weft yarn II, the third weft yarn III, and the fourth weft yarn IV, forming the front weft float W on the right side of the elastic band. The seventh warp yarn 7 is woven with the second weft yarn II, the third weft yarn III, and the fourth weft yarn IV, forming the back warp float C on the reverse side of the elastic band.
[0088] The eighth warp yarn 8 is woven with the first weft yarn I, the third weft yarn III, and the fourth weft yarn IV to form the front warp float J on the front side of the elastic band.
[0089] The ninth warp yarn 9 is woven with the first weft yarn I, the second weft yarn II, and the fourth weft yarn IV, forming the right-side weft float W on the front of the elastic band. The ninth warp yarn 9 is woven with the first weft yarn I, the second weft yarn II, and the fourth weft yarn IV, forming the wrong-side warp float C on the reverse side of the elastic band.
