- Polymeric Fiber Ion Exchange for Sulfur Removal and Higher Tenacity
Halide acid ion exchange removes sulfate from never-dried polymeric fibers, cutting sulfur below 3 wt% to improve tenacity and processing economics.
- Aramid Copolymer Yarn Halide-Acid Washing for Low Sulfur Tenacity
A base wash followed by halide acid treatment removes sulfate sulfur from never-dried aramid copolymer yarn and raises tenacity.
- Halide Ion Exchange in Polymeric Fibers for Sulfur Removal
Halide acid treatment displaces sulfate from never-dried polymer fibers, lowering sulfur content and improving high-tenacity fiber economics.
- Aramid Copolymer Yarn Halide Acid Wash for High Tenacity
Base neutralization followed by a halide acid wash lowers sulfate in never-dried aramid copolymer yarn and supports higher tenacity.
