Alternatively, the high-tenacity water-soluble PVA fiber according to the present invention can be prepared by subjecting a solution of a PVA polymer of the kind as described above to gel spinning so that the residence time of the resultant gelled filament in a cooling bath is at least 5 sec and drawing the resultant coagulated filament or Infinite Material Solutions 2.85mm AquaSys 120 2.85mm Being a water-soluble filament, AquaSys 120 dissolves with tap water only, with no harsh chemicals, keeping you safe and eliminating the risk of leftover residues. AquaSys 120 is hydrophilic and biocompatible. This means its a nontoxic and noncarcinogenic composite filament that can be used with engineering-grade build filaments.
Dec 08, 2020 · PVA Filament:The Complete 3D Printing Guide. by 3DSourced Solomon December 8, 2020. June 3, 2021. PVA filament (Polyvinyl Alcohol) is perhaps best known for being mistaken for Polyvinyl Acetate (white glue), as both use the same acronym. Perhaps its second most defining feature then, is that its entirely water soluble, and non-toxic. TENLOG 3D Printer 1.75mm PVA FilamentPVA wire, like water-soluble wire, is a support material and is well matched with PLA. TENLOG 3D Printer 1.75mm PVA Filament Features:1. Easily soluble in water. 2. Relative flexibility:able to bend to a specific angle. 3. As a supporting material, it matches well with PLA. 4. US5110678A - Synthetic polyvinyl alcohol fiber and process Each filament of the PVA fiber of the present invention having a structure comprising an aggregate of substantially innumerable fibrils, the fiber has high strength, elastic modulus, and

The process of the present invention comprises wet spinning or dry-jet-wet spinning a PVA-based polymer soluble in water at not more than 100°C while using a dope solvent and a solidifying solvent each comprising an organic solvent, wet drawing the solidified filaments, subjecting the drawn filaments to extraction treatment and then drying, and further subjecting the filaments to heat
