摘要： A method of preparing a vinyl collagen microsphere polyamide fiber composite material includes the following steps: step 1: modifying a collagen with methacrylic anhydride to obtain a vinyl collagen, then emulsifying and cross-linking the vinyl collagen to obtain vinyl collagen microspheres; step 2: treating a polyamide fiber substrate with formaldehyde to obtain a hydroxylated polyamide fiber substrate, treating the hydroxylated polyamide fiber with (3-mercaptopropyl)trimethoxysilane (MPS) to obtain a sulfhydrylated polyamide fiber substrate; and step 3: modifying the sulfhydrylated polyamide fiber substrate with the vinyl collagen microspheres to obtain the vinyl collagen microsphere polyamide fiber composite material.
