The invention discloses a digital inkjet printing method employing a compact siro spinning viscose fabric. The method comprises the following steps: (1) producing yarns of a viscose fabric by a compact siro spinning technology; (2) carrying out dual-color intelligent free weft selection by an intelligent shuttleless loom, and feeding wefts according to the weft design structure sequence to weave cloth; (3) carrying out pretreatment on the viscose fabric, including singeing, desizing, scouring, bleaching and starching; (4) preparing a dye ink; (5) printing; and (6) carrying out treatment on the viscose fabric after printing, including ageing, washing and setting. The viscose fabric is printed by digital inkjet printing equipment and ink; the technology is simple; registered colors for printing and dyeing are various; the environment is not polluted by ink printing; energy sources are saved when added value of a product is improved; the pattern effect is vivid; moire fringe transition is relatively natural and is relatively close to the real pattern effect; and the stereoscopic impression can be displayed through mobile phone photographing.
