Preparation of Collagen/PVA Composite Fiber

Abstract:

Article Preview

Alkali was used to extract collagen from chrome shavings. Grafting modification of collagen was carried out with acrylic ester as grafting monomers. The structure of the product was characterized using infrared spectroscopy. Spinning liquid was prepared with collagen and PVA(polyvinyl alcohol). Collagen /PVA composite fiber could be produced by wet spinning. The results showed that the optimal conditions of collagen grafting reaction were as follows: the dosage of modified monomers was 30% of collagen (mass fraction), the addition of emulsifier was 10% of butyl acrylate (mass fraction), reaction time was 2h and reaction temperature was 70°C. The collagen composite fiber had a strength of 3.65 cN/dtex and a elongation of 19%. The composite fiber had certain spinnability.
