The invention discloses a forming process of high-end dacron fabric. The forming process includes the following steps that 1, two functional high polymers are processed in fusion composite spinning equipment, and balanced composite monofilament fibers are formed; the fusion composite spinning equipment further comprises an air jet pipe head, multiple blades are further formed on the air jet pipe head, and air flowing at high speed blows the blades to drive a die stripping head to be in a rotary state; 2, balanced composite monofilaments serve as warp and weft respectively according to the warpand weft arrangement, and balanced dacron fabric single layers are obtained through interweaving; 3, spiral fibers are formed by the balanced composite monofilament fibers formed in the step 1 in a making device; 4, the spiral fibers formed in the step 3 are connected with the two balanced dacron fabric single layers formed in the step 2 respectively. The uniformity of the two functional high polymers on the same position proportion is guaranteed, the stability of the performance of the composite monofilament fibers is improved, and the requirements of the high-end fabric are met.
