The invention relates to the field of textile functional finishing, and discloses an anion modified cotton fabric and a preparation method thereof. The preparation method comprises the steps that the cotton fabric is completely immersed in a BTCA-sodium hypophosphite mixed solution to be stirred for 10-15 minutes; then the redundant solution is removed through rolling; the rolling detention rate of the cotton fabric is controlled to be 96%-105% by weight; and the cotton fabric is sequentially dried, cured, washed and dried to obtain the anion modified cotton fabric. According to the preparation method, the technological process is simple, the spinning cost of the high-proportion colored fibers can be reduced, and the cotton fabric obtained through modification is low in dye uptake after being dyed, has good 'dye rejection' performance and has good application prospects. 本发明涉及纺织品功能整理领域，公开了一种阴离子改性棉织物及其制备方法，该方法包括：将棉织物完全浸没于BTCA-次亚磷酸钠混合溶液中搅拌10-15min，然后轧除多余溶液，控制棉织物的轧余率为96-105重量％，接着将棉织物依次进行干燥、固化、洗涤和烘干，得到阴离子改性棉织物。本发明
