- Hyaluronic Acid Fiber Spinning Without Toxic Solvents or Coagulation
Dry spinning with a parallel air stream forms pure hyaluronic acid microfibers and nanofibers without toxic solvents, added polymers, or coagulation baths.
- Circulating Degassing Filtration for High-Viscosity Spinning Dope
A vacuum-circulation loop with multi-mesh filtration removes bubbles and impurities from high-viscosity spinning dope for more uniform fiber spinning.
- Pure Hyaluronate Nonwoven Fabric Without PVA Binding Fibers
Wet spinning and solvent ratio control form pure hyaluronate nonwoven fabric without PVA, improving biocompatibility for patches and wound dressings.
- Meta-Aramid Fiber Preparation for Higher Elongation at Break
Two-stage polymerization with controlled stirring, pH, and wet spinning raises meta-aramid fiber elongation for comfort and filler hardness.
