[0050] Step 2: feeding the yarn into the colloid storage device so that the yarn is fully soaked with the colloid;

[0051] Step 3: Then the yarn soaked with colloid is sprayed out through the nozzle through the multi-axis linkage device, so that the yarn is arranged on the cloth bed according to the designed trajectory points. Assuming that the prepared fiber cloth has 100 yarns in the radial direction, 200 yarns in the weft direction, and 80 yarns in the multi-angle direction, the yarn spraying sequence is:

[0052] The first spray: the 1st warp, the 1st weft, the 1st multi-angle, the 50th warp, the 100th weft, the 40th multi-angle, the 100th warp, the 200th weft, the 80th multi-angle;

[0053] Second spray: 25th warp, 50th weft, 20th multi-angle, 75th warp, 150th weft, 60th multi-angle;

[0057] Until all yarns are sprayed;

[0058] Step 4: glue and spread the selected yarn along the designed trajectory to form the designed multi-angle fiber cloth;

[0059] Step 5: Drying the closely arranged multi-angle fiber cloth by a drying device;
