    摘要： In a process for producing a spinnable silica sol material, a viscosity value VS is stipulated which the spinnable silica sol material should have after ripening. A viscosity value VR corresponding to VS which the silica sol material has before ripening is ascertained. An aqueous acid solution and a hydrolysable silicon compound are combined. The combined mixture is evaporated to give a single-phase solution while measuring the viscosity of the mixture and the evaporation process is terminated upon reaching the viscosity value VR. The single-phase solution thus obtained is then ripened to give a silica sol material with the viscosity value VS. The process exhibits reduced waste and more exact reproducibility of the spinning sol properties during the synthesis and an increased space-time yield in the production of biologically degradable and/or resorbable fibers and nonwoven fabrics.
