Manufacturing process for weaving mini-jacquard and large-pattern clothing plain velvet fabric by adopting double-rapier loom

The invention provides a manufacturing process for weaving a mini-jacquard and large-pattern clothing plain velvet fabric by adopting a double-rapier loom. The mini-jacquard and large-pattern clothing plain velvet fabric is woven by taking the double-rapier loom as a machining tool, and cotton yarns and polyester cotton yarns as raw materials through processes of machining raw materials, warping, weaving, brushing and dyeing; and in the manufacturing processes, drafting adopts spring drafting manners of 4, 2, 8 and 6 as well as 3, 1, 7 and 5; pile warp consolidation adopts a combined W+V manner, and pile warps are interwoven with weft yarns in V-shaped and W-shaped manners, so as to form patterns; and then the fabric is brushed and dyed. The cotton yarns and the polyester cotton yarns are adopted, and the yarns are arrayed according to a certain rule; different organization and weaving processes are designed, so that current situations that a previous loom dobby only can be used for weaving plain-color clothi
