Manufacturing method for woven imitation knitting rib fabric

The invention provides a manufacturing method for woven imitation knitting rib fabric. According to the manufacturing method, cationic intermingle yarn (ITY) polyester composite yarns are used as raw materials of warp yarns and weft yarns, and each cationic ITY polyester composite yarn is formed by compounding a cationic fully-drawn yarn (FDY) and polyester pre-oriented yarn (POY) or a FDY and the cationic POY. The manufacturing method comprises the following processes: winding the cationic ITY polyester composite yarns onto a bobbin; performing a twisting operation on the cationic ITY polyester composite yarns on the bobbin; respectively setting the warp yarns and the weft yarns to form greige cloth; performing open-width continuous refining on the greige cloth in sodium carbonate and scouring agent-contained solution under the condition that the temperature is controlled to be 90-100 DEG C; performing presetting treatment; performing alkali peeling treatment; dyeing and finishing for coloring; and finally,
