Abstract

Superfine down-powder/viscose blend films were prepared and characterized for their dyeing properties. Down-powder with average size of $2.56{\mu}m$ were suspended in viscose dope and blend films were obtained by solution casting. When the blend films were dyed with acid dye, the dye uptake and K/S values increased with the increase in down-powder content. Amino-acid analyses showed that amino acid component of the down were not affected during the film formation, which confirmed the changes of dye uptake and K/S value.
