发明名称 Method for making fiber having biodegradable superabsorbent particles attached thereto
摘要 A method for making fibers having particles attached thereto, comprising blending a carboxyalkyl cellulose and a starch in water to provide an aqueous gel; treating the aqueous gel with a first crosslinking agent to provide a crosslinked gel; drying the crosslinked gel to provide a solid; comminuting the solid to provide a plurality of particles; combining at least a portion of the plurality of particles with a aqueous dispersion comprising cellulose fibers and a first water-miscible solvent and, optionally, a second crosslinking agent, to provide a mixture comprising swollen particles and cellulose fibers; and adding a second water-miscible solvent to the mixture to provide fibers having particles attached thereto.
