The ground bar GB2 is threaded with 50D polyester filament in a full threading manner, and is knitted into loops on the back needle bed to form a 1-1-1-0 / 1-1-0-1 / / stitch, and the ground bar GB6 is threaded with 100D / 1F polyester filament in a full threading manner, and is knitted into loops on the back needle bed to form a 1-1-1-2 / 2-2-1-0 / / stitch, and the ground bar GB6 cooperates with the ground bar GB2 to form a base layer of the three-dimensional pattern area 1 surface layer. The jacquard bars JB3.1 and JB3.2 are threaded with 100D / 72F cationic low-elasticity twistless yarn DTY in a full threading manner, and are knitted into loops on the back needle bed to form a 1-1-1-0 / 2-2-2-3 / / stitch, thereby forming a first pattern layer on the three-dimensional pattern area 1 surface. The ground bar GB4 is threaded with 20D / 1F polyester filament in a full threading manner, and is knitted into loops on the front and back needle beds alternately to form a 0-1-1-0 / 1-0-0-1 / / stitch, thereby forming a spacer layer connecting the three-dimensional pattern area 1 surface layer and the base layer.
