As shown in FIG. 1, the thirty-three steel buckles 60 are represented by 1a to 33a, the multiple warps 30 are denoted by A, B, C, and D. The multiple latex yarns 40 are indicated by R, and the plural latex threads 41 are represented by R1, R2, and R3. A number of first warps A is 3, a number of second warps B is 16 (2 in 1 inserting), a number of third warps C is 174 (3 in 1 inserting), and a number of fourth warps D is 174 (3 in 1 inserting). A number of the latex yarns R is 4 (one latex yarn R is arranged on a needle point, and the other latex yarns R is arranged on a selvage). A number of first latex threads R1 is 145 (5 in 1 inserting), a number of second latex threads R2 is 145 (5 in 1 inserting), a number of third latex threads R3 is 28 (inserting through a first frame 50), wherein a numerical reference 1 to 14 represent fourteen frames 50. Each of the multiple latex yarns 40 has a covering layer so as to enhance reinforcement of each latex yarn 40, wherein the covering layer of each latex yarn 40 is arranged on the needle point and the selvage.

As illustrated in FIG. 3, each of multiple circles denotes high, each of multiple X marks represents low, wherein the high and the low have eight high-and-low sequences 70. The fourteen frames 50 are pulled by the multiple flower chains based on the eight high-and-low sequences 70 so as to weave the plurality of cloth layers 31, and the multiple elastic layers 32 are weaved among the plurality of cloth layers 31, thus producing the elastic band 20.
