    摘要: The present invention provides cellulosic fibers having high wet bulk and methods for their preparation. In one embodiment, the invention provides cellulosic fibers catalytically crosslinked with glyoxal and, optionally, a glycol. In another embodiment, cellulosic fibers are crosslinked with a combination of glyoxal and a glyoxal-derived resin selected from the group consisting of a glyoxal/polyol condensate, a cyclic urea/glyoxal/polyol condensate, a cyclic urea/glyoxal condensate, and mixtures thereof.
