Structure and Properties of the Anion Functional Alginate Fiber

An anion functional alginate fiber is developed by blended spinning, consisted by chitosan, nanometer tourmaline and other additives. Box-Benhnken Design response surface experimental design method is used to optimize the factors influencing anion emission, and the optimal anion releasing condition is as following: tourmaline 1.01g/100ml, coupling agent 0.23ml/100ml, dispersant 0.31g/100ml. By the optimal condition, the anion releasing quantity is 2950. Then FTIR, SEM, XRD are used to characterize the fiber, and the crystallinity is 0.78.
