Biofunctional properties of polyester fibers grafted with chitosan and collagen

Poly(ethylene terephthalate) (PET) fiber was treated with 60Co‐γ‐ray and grafted with acrylic acid (AA). The resulting fibers were further grafted with chitosan (CS) via esterification. Afterward collagen (COL) was immobilized onto CS‐grafting fibers. The antibacterial activity of CS against Staphyl...

Summary:Poly(ethylene terephthalate) (PET) fiber was treated with 60Co‐γ‐ray and grafted with acrylic acid (AA). The resulting fibers were further grafted with chitosan (CS) via esterification. Afterward collagen (COL) was immobilized onto CS‐grafting fibers. The antibacterial activity of CS against Staphylococus aureus, Escherichia coli, and Pseudomonas aeruginosa was preserved after COL‐immobilization. After immobilizing COL, the L929 fibroblasts cell proliferation was promoted than CS‐grafting PET fiber. The results indicate that by grafting with CS and immobilizing with COL, PET fibers exhibited both antibacterial activity against four pathological bacteria and improvement in the proliferation of fibroblast.
