Feasibility study of regenerative fibers for water pollution control
1970
Fuest, R. W. | Smith, Malcolm Jules
High molecular weight organic polymers co-spun with fiber-forming polymers and cross linking agents have been successfully spun into fiber and chemically treated to produce ion exchanging fibers, as opposed to the conventional beads. Styrene sulfonic acid cation exchange fibers having capacities up to 4.2 meg/gm dry fiber were prepared, using polypropylene and polybutadiene as fiber-forming polymer and cross linking agent respectively. Selectivities of fibers were similar to those of conventional beads, but different selectivities for the fibers may be possible due to anisotropic swelling of the fibers. Several other types of fibers were successfully fabricated.
