Background

Warp-knitted spacer fabrics have good compression deformation capacity, resilience performance and air permeability, can effectively relieve human body pressure and absorb impact energy, and are increasingly widely applied, such as automobile cushions, vamp materials, mattresses and the like. The common warp-knitted spacer fabric at present comprises three structures, namely a surface layer, a middle layer and a bottom layer, wherein the middle layer is formed by yarns and filament yarns or monofilaments and is connected with the surface layer and the bottom layer to form a spacer structure of the middle layer. The surface layer and the bottom layer may be the same or different in structure, for example, the surface layer and the bottom layer are both compact structures, one surface may be compact structure, and the other surface may be plain structure, small pattern, jacquard, or meshes with different sizes are generated on both surfaces.

The PUFF structure fabric is one of warp-knitted spacer fabrics, and as the name suggests, the fabric of the warp-knitted spacer fabric contains a PUFF (foam) shaped structure, and different parts of the fabric form bulges or depressions with different thicknesses, so that the fabric with set three-dimensional shapes, meshes or lines is formed, and the functional requirements of the existing market on the increasingly diversified warp-knitted spacer fabric are met. Currently, double-needle bed sheet jacquard warp knitting machines are mainly adopted for preparing warp-knitted spacer fabrics. The warp-knitted spacer fabric to be formed into a PUFF structure is mainly formed by patterning different yarn amounts with different let-off amounts on the surface layer, the middle layer and the bottom layer. In the aspect of controlling different let-off quantities of different parts of the warp-knitted spacer fabric, a coil model of a common guide bar is not suitable for a jacquard coil, and because the let-off quantity of the jacquard guide bar is larger than that of the common guide bar, the common manufacturing process cannot manufacture the PUFF structural fabric with three-color jacquard effects with different thicknesses on a surface layer, a middle layer and a bottom layer.
