A copper-containing, antimicrobial and antiviral non-woven fabric and a preparation method therefor. The preparation method therefor comprises the following steps: subjecting a fiber material to fiber web formation, pre-wetting and spunlaced reinforcement in order to obtain a spunlaced fiber cloth-based fabric; subjecting the spunlaced fiber cloth-based fabric to padding and sizing in an organic complex copper solution, in order to obtain a copper-containing spunlaced non-woven fabric, with the copper content on the copper-containing spunlaced non-woven fabric being ≥500 ppm; and subjecting the copper-containing spunlaced non-woven fabric obtained from padding and sizing to drying and winding. The method has the advantages of easy industrialization, a simple process and a short production cycle; the copper-containing, antimicrobial and antiviral non-woven fabric prepared by the method has excellent antimicrobial and antiviral properties; and the copper-containing, antimicrobial and antiviral non-woven fabric can be widely used.
