Dyeing method for cool jacquard knitted air layer fabric

The invention discloses a dyeing method for a cool jacquard knitted air layer fabric. The dyeing method comprises the following steps that deoiling and washing of gray cloth, back dyeing, reduction cleaning, drying, front paint ink spray printing, drying, baking and packaging. The dyeing method for the cool jacquard knitted air layer fabric has the advantages that the jacquard knitted air layer fabric is put in a high-temperature high-pressure airflow dyeing machine, polyester filaments on a bottom layer and polyester low stretch yarn on a middle layer are dyed, reduction cleaning is carried out to remove the front floating color, sizing is carried out, then nano-paint all-over spray printing is carried out on front ultrahigh-molecular-weight polyethylene filaments, drying, baking and sizing are carried out, a cool bedspread and sofa cover fabric with a diamond-shaped grid-shaped concave-convex pattern is produced, the middle layer of the fabric is a polyester low stretch yarn floatingthread, air holes distin
