| Résumé : |
Regenerated protein fibers were wet-spun by collagen protein extracted from chrome shavings. A “pure” collagen protein extract of molecular weight _> 100,000 Da and chromium content <5 ppm was produced. To increase the spinning stability and physical strength of the fibers, the aqueous collagen solution was mixed with polyvinyl alcohol containing _<0.3 percent glutaraldehyde in a subsequent unique treatment. Good spin ability was obtained when the viscosity was _>1,000 cps. Optimal spin ability conditions were obtained at water temperature of 30~35°C in a coagulating bath containing a mixture comprising a minimum of 40 percent Na2SO4 and 1 M H3BO3. A water-resistant regenerated protein was eventually produced by chemical crosslinking using 15 percent Na2SO4, 0.5 percent glutaraldehyde, and 0.25 percent formaldehyde. The regenerated protein fiber had a specific gravity of 1.3 g/cm2, tensile strength of 1.32~2.0 g/d, and elongation of 29~38 percent. |
