Polymeric polycarboxylic acid crosslinked cellulosic fibers |
摘要 |
Cellulosic fibers intrafiber crosslinked with a polymeric polycarboxylic acid crosslinking agent are disclosed. In one embodiment, the polymeric polycarboxylic acid is polyacrylic acid and, in another embodiment, the polycarboxylic acid is polymaleic acid. Methods for forming cellulosic fibers having stable intrafiber crosslinks and for forming crosslinked cellulosic fibers having low knot level are also disclosed.
