The invention relates to a method for the production of cellulose shaped bodies according to the dry-wet extrusion method (Lyocell method) with high degree of whiteness and bioactive action for use in the textile sector and paper production. In the context of the invention, the term "bioactive" refers to antimicrobial efficacy, based on the antibacterial action of the element silver, which is used as nanoscale reagent for increasing the efficacy thereof. The chemically inert and, at the same time, bactericidal effect is used in the production of sports and leisure clothing with a high degree of whiteness and papers with a long shelf life. Use is possible in the medical sector, for example, for wound dressings, textiles for hospitals, and in the filter and packaging industry.
