Study on blending modification of superabsorbent poly(acrylic acid-co-acrylamide) fibers

Modified by blending with organic or inorganic substances,superabsorbent poly(acrylic acid-co-acrylamide) fibers were prepared.The effect of added components on the morphology,thermal properties and water?-absorptive capacity of the modified fibers were discussed in detail.The results show that the glass transition temperature of fibers blended with PVA was lowered and the fibers became more flexible,and that the absorptive speed and the equilibrium amount of water absorbency of sepiolite-filled fibers were increased obviously.
