The invention relates to functional spunbonded fabrics incorporating fibers made from non-fusible polymers containing one or more functional additives. The fibers are interwoven and interlocked to form a firm fleece composite, have different lengths, and have aspect ratios above 1,000. The fibers have a mean diameter of 0.1 to 500 micrometres and diameter variations within a fiber and/or among each other of at least 30%. The fibers contain more than 40 wt % of finely distributed functional additives in solid and/or liquid form. The spunbonded fabric is produced from a spinning solution containing the non-fusible polymer dissolved in a direct solvent and at least one functional additive. The spinning solution is extruded out of a spinneret, and the resulting strands are drawn in the longitudinal direction to form filaments or fibers, stabilized and laid down to form a fleece fabric. Exemplary spunbonded fabrics include clothing, technical textiles and filters.
