Description

Technical Field

[0002] With the development and research of double-needle-bar jacquard warp knitting machines and the exploration and improvement of technology, the colors and patterns of double jacquard jacquard fabrics have been improved. However, most of the current double-needle-bar double jacquard fabrics use an active warp beam feeding device, or only one jacquard bar uses an active warp feeding mechanism and the other jacquard bar uses a passive creel feeding mechanism. It is necessary to consider the tension problem when designing the pattern, which limits the pattern design. Moreover, the current double jacquard fabrics, especially the jacquard fabrics used for shoe uppers, are mostly three-layer structures including a surface layer, a bottom layer and a connecting layer, and the connecting layer is formed by yarns being circled on the front and rear needle beds. The three-layer fabric formed is relatively thick and has poor air permeability. In addition, the current jacquard fabrics have a weak sense of layering, the jacquard effect on the same upper fabric is single, and there is no multi-layer pattern layout for the upper structure, resulting in a single upper structure.
