In the surface layer 10, a plurality of first stitches are intertwined with each other in the longitudinal direction to form a column, and a plurality of first stitches are arranged in a transverse direction to form a course. The pattern yarn 23 includes a floating line segment 22 and an interweaving segment 21. The bottom of the surface layer 10 is arranged in the form of a floating line to form a support layer 20. The interwoven section 21 extends along the first coil corresponding to the position of the first coil and forms a second coil. The second coil is A plurality of second coils are intertwined with each other in the longitudinal direction to form a longitudinal row, and a plurality of second coils are arranged in a transverse direction to form a row. The fabric formed in this embodiment is a two-layer structure.

As a preferred mode of the present invention, the second coil is located below the first coil, and the first coil and the second coil abut against each other.

As a preferred mode of the present invention, the fabric body further includes a bottom layer 30 compounded on the lower surface of the support layer 20, and a part of the floating line segment 22 is penetrated on the bottom layer 30 and connects the surface to the bottom layer 30. The layer 10 is connected to the bottom layer 30, and the float segment 22 can be passed through the bottom layer 30 only, or can be looped together with the yarns of the bottom layer 30.

As a preferred mode of the present invention, the ground yarn 11 is a fish thread, and the pattern yarn 23 is a colored yarn, specifically a colored high-elastic yarn. Under the action of the characteristics of the fish thread, the surface The fish threads are formed on the surface of the colored high-elastic yarns like film fish scales to form a reflective and bright effect.
