1. the double-jacquard shoe product mainly takes a plane as a main part, can reflect the product characteristics only through the changes of the mesh size, the mesh shape and the thick and thin organizational structure of the fabric, and is lack of the appearance of 3D (three-dimensional) appearance;
2. the double-jacquard shoe product is mainly designed by a single-color or double-color vamp pattern, is monotonous in vision, lacks of multi-color matching application, and can enable the product to be richer in visual impact;
3. the conventional warp knitting jacquard three-needle looping principle mostly adopts a mode of 2 jacquard combs in the same direction for lapping yarns to form a fabric, the jacquard combs can not form solid grains in a matching way, and the thickness of the fabric can only be formed.
