Relation between dynamic mechanical properties and dye diffusion behavior in acrylic fibers from polymer blends

摘要

AbstractThe extension of the relation between the dynamic viscoelastic parameters (“E” and tan δ) and diffusion coefficient (D) to modified acrylic blend fibers indicates that the dependence of dye diffusion on polymer chain mobility is a general phenomenon not limited to a single component system. The relationship ofDto mechanical properties permits one to “tailor” fibers with good mechanical properties while maintaining adequate dye‐diffusio
