- 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.
- High-Elasticity Nylon Tire Cord Through Moisture-Controlled Drying
Drying raw nylon cord to 2-5% moisture raises elastic modulus while limiting shrinkage, yarn breakage, and fatigue loss.
- Aromatic Polyamide Fiber Fineness Control for Thin Reinforced Cables
Finer aromatic polyamide filaments with controlled fibrils enable thinner composite cables and catheters without losing strength or flexibility.
- Hemicellulose-Rich Lyocell Fiber for High Water Retention
Using hemicellulose-rich pulp creates lyocell fibers with higher water retention and viscose-like fibrillation without strength-loss pre-treatments.
- Melt-Spun PAN/Lignin Fibers Using a Removable Solvent
A meltable solvent lowers PAN processing temperature for melt spinning, avoiding degradation while enabling lignin-based carbon fiber precursors.
- Beaded Core-Shell Fibers for Phase-Change Thermoregulation
Coaxial wet-wet electrospinning places coconut-oil PCM in a cellulose shell to absorb and release heat for stable temperature control.
