The fabric structure comprises warp straight chain weaves G1 and G2, weft weft weaves J1 and J2 connecting adjacent straight chain weaves to form a fabric frame layer with different mesh changes; weft weft weaves G3 and G4 provide warp shrinkage performance, and are woven together with weft weft yarns with N < 95 in a single cycle according to the requirements of pattern design. Among them, G1, J1, and J2 are filaments, and G2, G3, and G4 are spandex. The pattern organization is selected according to the needs of the pattern design. The utility model is beneficial in that: 1. The reverse yarn of the weft-inserted organization J1 and J2 makes the linear density of the yarn superimposed, improves the structural strength of the fabric, and interweaves with spandex to increase the weft tensile performance of the fabric. Under the action of the 7.5Lbf force of the LTD03 test method, its warp and weft tensile performance is ≥80%; 2. The chain organization structure of spandex G2 and its inherent shrinkage increase the tightness between the coils, increase the sliding resistance between the yarns, and make the yarns not fall apart after the fabric is damaged. 3. After the fabric is damaged, it still does not fall apart after 50 washings under the AATCC 135 test method.

[0006] 2. JB1 and JB2 described in the utility model correspond to J1 and J2 of the above patent, but are not limited to reverse inlay yarn, that is, the appearance of the fabric is more variable;

[0007] 3. The weft opening of the fabric of the utility model is stronger than that of the above patent, and the application range will be wider;

[0008] 4. The pattern yarn of the fabric described in the utility model adopts woven yarn, so that the pattern of the fabric has the advantages of elastic contour and thick flower blocks, thereby enhancing the three-dimensional effect of the fabric, and can effectively improve the problems of pattern yarn slippage and yarn throwing in the production process.
