The invention provides a viscose knitted fabric manufacturing method, the manufacturing process is more environmentally friendly, and manufactured fabric is good in bulkiness and softness and quite comfortable. The process comprises the steps of selecting bamboo fibers and wood fibers extracted from wood in a sustainable development forest area, and respectively putting the bamboo fibers and the wood fibers into a digester for cooking and pulping; then sequentially performing washing, performing pulping by a pulping machine, mixing wood dissolving pulp and bamboo dissolving pulp, performing dipping in a dipping barrel filled with alkali liquor, performing squeezing by a squeezer, adding carbon disulfide by a yellowing machine for yellowing, performing grinding, performing filtering, feeding a filtered material into a spinning machine for spinning, performing drafting, refining and desulfurizing, and performing drying to obtain viscose fibers; blending the obtained viscose fibers and regenerated polyester into yarns, wherein the weight ratio of the viscose fibers to the regenerated polyester fibers is 1:(0.6-0.9); and forming a blank by weaving on a circular knitting machine, and performing cylinder matching, end stitching, dyeing and rinsing, dehydration, slitting, high setting, dyeing, dehydration, cloth tidying, baking setting, napping, finished product setting and packaging,so as to obtain the finished fabric.
