Abstract: Spent collagen is added into a toluene-reduced sea-island microfiber nonwoven material system.The vinyl collagen impregnation process is then investigated to enable the modified collagen with a carbon-carbon double bond to form film in polyamide (PA) microfiber nonwoven material, thus replacing the polyurethane film formation process in the current process.It is found that the prepared collagen/polyamide fiber nonwoven materials present improvements in apparent density, uniformity, moisture absorption, moisture permeability and tensile strength.Both moisture absorption and moisture permeability of the materials are superior to PA/PU substrates made by traditional process.The softness of the substrate is also significantly improved after being treated by adding lipid.Final collagen/microfiber nonwoven composite substrate constructed in this study has good moisture absorption and permeability, superior softness and elasticity, and its mechanical properties can be comparable to those of conventional PA/PU substrates.
