The invention relates to a far-infrared anion polyester fiber home textile fabric and a preparation method thereof. The far-infrared anion polyester fiber home textile fabric is formed by weaving, by weight, 20-40% of apocynum venetum fibers, 30-60% of modal fibers and 10-30% of anion polyester fibers. The preparation method includes the specific process steps of blending, opening and picking, carding, drawing, roving, spinning and the like. The home textile fabric prepared through the method is smooth in surface, soft in hand feeling, bright in color, capable of absorbing moisture and breathable. By means of the home textile fabric, human body microcirculation can be improved, tissue cells are activated, the metabolic function is improved, immunity is enhanced, metabolism is promoted, bacteria breeding is inhibited, and the fabric especially has good auxiliary treatment effects on hypertension, chronic bronchitis, asthma, cold and insomnia. Meanwhile, the fabric can be used for preventing bedsore, eczema, chronic dermatitis, pruritus and other diseases.
