When common polyester yarns are adopted as connecting yarns, and the surface layer and the bottom layer are woven by non-thermoplastic fibers, the coil sizes of the surface layer and the bottom layer can only be regulated and controlled by weaving, and the stitch length is limited greatly. The connecting wires are often exposed between the columns of the surface layer loops, thereby causing hooking or pilling, as shown in fig. 3. In fig. 3, the area indicated by the box is the slit of the column of coils, and the larger the slit is, the more likely the connecting wire is to come into contact with the outside, and the more the hooking and the pilling are caused.
