摘要
Substantially water-insoluble, water-swellable, non-regenerated, carboxyalkyl cellulose fibers, wherein the fibers have a surface having the appearance of the surface of a cellulose fiber, and wherein the fibers include a plurality of non-permanent intra-fiber metal crosslinks and a plurality of permanent intra-fiber crosslinks; and fiber bundles that include the fibers. Methods for making substantially water-insoluble, water-swellable, non-regenerated, carboxyalkyl cellulose fibers, wherein the fibers have a surface having the appearance of the surface of a cellulose fiber, and wherein the fibers include a plurality of non-permanent intra-fiber metal crosslinks and a plurality of permanent intra-fiber crosslinks.
