Effect of heat treatment on the mechanical properties of Casein-g-Poly(acrylonitrile) fibers

摘要：

Four kinds of casein-g-poly (acrylonitrile) fibers with different casein content were prepared, and mechanical properties were investigated after different heat treatment. The results show that the grafted casein fibers were sensitive to temperature. With the increase of casein content, the effect of cross-linking performance in fiber increased after high temperature treatment. The strength and elongation at break both trended to increase. But the colors of fibers gradually changed into yellow under the higher temperature, due to the thermal oxidative decomposition of casein. SEM observations on the cross-section surface of modified fibers show the different structures in grafted casein fibers with different casein contents.
