The invention relates to a process for manufacturing miscellaneous fleece. A double-layer rigid rapier loom is used as a processing tool, and polyester filament yarns are adopted in fluff and base fabric. The miscellaneous fleece is formed by yarn twisting and sizing, beam warping, weaving, cropping and fabric dyeing process weaving. By the filament twisting and sizing and the specific weaving process, the miscellaneous fleece manufactured by the process has full and elastic fleece surface and high upright degree, and both the abrasion resistance and the color fastness to washing reach level 4 to 5; the washing size variation is 0.4 percent in the warp direction and 0 percent in the weft direction, and the fluff height reaches 1.3 to 1.5 millimeters; and the miscellaneous fleece manufactured by the process is widely applied to costumes, high-grade gift packages and the like.
