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, comprising:

• 1) changing a guide bar configuration:
• placing a jacquard guide bar on an outside of a 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, a yarn inlaid stitch of the jacquard guide bar is 0-1-1-1/2-1-1-1//;
• and a yarn inlaid stitch of the ground guide bar is 0-1-1-1/3-2-1-1//;
• 2) changing a 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 a needle and a position in front of the needle of a needle bed of the jacquard warp knitting 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 a fabric surface presents a 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 a yarn color of the rear guide bar;
• re-defining a basic stitch of the jacquard:
• No. (1) color, namely defining a red color as a cord stitch, wherein a yarn inlaying code is 1-0/2-3//;
• No. (4) color, namely defining a green color as a tricot stitch, wherein the yarn inlaying code is 1-0/1-2//;
• No. (12) color, namely defining a white color as a mesh stitch, wherein the yarn inlaying code is 1-0/0-1//;
• No. (2) color, namely defining a yellow color as the weft laid-in stitch, wherein the yarn inlaying code is 0-0/1-1//;
• 4) drawing 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;
• and
• 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.
