1. A textile with elasticity, comprising:
a first weft unit comprising a plurality of first elastic weft yarns adjacent and parallel to each other;
a second weft unit comprising a plurality of second elastic weft yarns adjacent and parallel to each other, wherein the first weft unit and the second weft unit are distributed staggeredly at a front side of the textile with elasticity;
a third weft unit comprising a plurality of third elastic weft yarns adjacent and parallel to each other;
a fourth weft unit comprising a plurality of fourth elastic weft yarns adjacent and parallel to each other, wherein the third weft unit and the fourth weft unit are distributed alternately at a rear side of the textile with elasticity and corresponded to the first weft unit and the second weft unit respectively;
wherein the first elastic weft yarns are woven to and fro in a continuous first S-shaped configuration by a first fabric, and the second elastic weft yarns are woven to and fro in a continuous second S-shaped configuration by a second fabric, four of the first elastic weft yarns are formed into a first sub unit that forms the first S-shaped configuration and four of the second elastic weft yarns are formed into a second sub unit that forms the second S-shaped configuration, and the first sub unit is adjacent to the second sub unit and separated from the second sub unit by a distance, the distance is continuous along an entire length of the first sub unit and the second sub unit;
wherein the third elastic weft yarns and the fourth elastic weft yarns are woven continuously into continuous S-shaped by a single fabric, and adjacent to each other are separated by the distance;
wherein each of the first elastic weft yarns and each of the third elastic weft yarns are parallel to each other and separated by a gap between the front side and the rear side;
wherein each of the second elastic weft yarns and each of the fourth elastic weft yarns are parallel to each other and separated by the gap; and
a warp yarn layer comprising a plurality of elastic warp yarns longitudinally disposed within the gap, wherein each of the elastic warp yarns comprises a twine tying one of the elastic warp yarns as a center for binding the first weft unit, the second weft unit, the third weft unit and the fourth weft unit to keep the distance;
wherein the first fabric and the second fabric overlap each other in an area that is in an one end of the distance between the first sub unit and the second sub unit and in a direction of the gap between the front side and the rear side of the textile with elasticity.
