  • Nonwovens are textile fabrics in which the cohesion of the fibers is ensured not by weaving or knitting, but by interlocking and sometimes also gluing after the fibers have been swirled. Because of the wide range of possible uses and the low production costs, nonwovens production continues to show high annual rates Growth rates. The advantages of these nonwoven materials lie in particular in the high moisture absorption, the high variability of density and thickness as well as the extensive surface anisotropy, which results in the numerous possible uses, e.g.
  • Nonwovens made from continuous filaments are preferably made from synthetic fibers such as polyester, polyacrylonitrile or polypropylene. Viscose fibers are preferably used as short or staple fibers for the manufacture of nonwovens.
  • a process which has been known for a long time for the production of molded articles from regenerated cellulose consists in the precipitation of a solution of cellulose carbamate (EP-A-57 105, EP-A 178 292) which is obtained by reacting cellulose with urea with thermal splitting of the urea into isocyanic acid and Ammonia and reaction of the isocyanic acid with the OH groups of the cellulose is formed.
