[0049] (2) threading of the comb bars, all comb bars are fully threaded, wherein the ground comb GB1 threaded the first yarn, the jacquard comb bars JB2.1 and the jacquard comb bars JB3.1 threaded the second yarn, the jacquard comb bars JB2.2 and the jacquard comb bars JB3.2 threaded the third yarn, the ground comb GB4 threaded the fourth yarn, and the ground comb GB5 threaded the fifth yarn, and the third yarn and the fourth yarn have different yarn characteristics;

[0050] (3) Yarn letting off: the jacquard bars JB2.1, JB2.2, JB3.1 and JB3.2 use a passive creel letting off mechanism to feed the yarn, while the ground bars GB1, GB4 and GB5 use an active warp letting off mechanism to feed the yarn;

[0051] (4) Weaving: the first yarn passed through the ground comb GB1 is only used to weave a chain stitch on the front needle bed to enhance the longitudinal stability of the fabric; the jacquard combs JB2.1 and JB3.1 are passed through the second yarn, and are alternately weaved on the front and rear needle beds to form a jacquard layer of the second yarn; the jacquard combs JB2.2 and JB3.2 are passed through the third yarn, and are alternately weaved on the front and rear needle beds to form a color jacquard layer of the third yarn; the ground comb GB4 is passed through the fourth yarn, and is used to weave a chain stitch on the rear needle bed to enhance the longitudinal stability of the fabric; the ground comb GB5 is passed through the fifth yarn, and is used to weave a three-needle warp plain stitch on the rear needle bed to improve the lateral stability of the fabric;
