Preparation method of jacquard sandwich mesh fabric with two-colored surface

A preparation method of a jacquard sandwich fabric with a two-colored surface, employing a jacquard warp knitting machine, characterized by comprising the following steps:

• 1) Changing the guide bar configuration:
• placing the jacquard guide bar on the outside of the ground guide bar, which means that the first one is the jacquard guide bar, the second one is the ground guide bar;
• after the change, the yard inlaid stitch of the jacquard guide bar is 0-1-1-1/2-1-1-1H;
• and the yard inlaid stitch of the ground guide bar is 0-1-1-1/3-2-1-1//;
• 2) Changing the jacquard control signal:
• adding a new fluted disc controller and a control sensor to obtain two jacquard control signals, respectively at a position back to the needle and a position in front of the needle of the needle bed of the machine;
• 3) If the yarn inlaid stitch of the outside guide bar is an open stitch, the stitch of the rear guide bar is covered, while the fabric surface presents the yarn color of the outside guide bar;
• if the yarn inlaid stitch of the outside guide bar is a weft laid-in stitch, the stitch of the rear guide bar is not covered, and the fabric surface presents the yarn color of the rear guide bar;
• Re-defining the basic stitch of the jacquard:
• No. (1) Color, namely defining the red color as the cord stitch, wherein the yarn inlaying code is 1-0/2-3//;
• No. (4) Color, namely defining the green color as the tricot stitch, wherein the yarn inlaying code is 1-0/1-2//;
• No. (12) Color, namely defining the white color as the mesh stitch, wherein the yarn inlaying code is 1-0/0-1//;
• No. (2) Color, namely defining the yellow color as the weft laid-in stitch, wherein the yarn inlaying code is 0-0/1-1//;
• 4) Drawing the jacquard patterns using the redefined jacquard basic stitch colors;
• 5) Converting the designed pattern into a graphic diagram and continuously modifying the pattern through the graphic diagram;
• 6) After finishing the pattern design, directly exporting a knitting document, importing the document into a machine file, and producing the jacquard sandwich mesh fabric with a two-colored surface.
