In this study a process of dying cotton fabrics 100% was carried out
by direct dye Solophynel GLE Yellow and after that it was treated by
cationic softening agent for improving the fastness to washing and
rubbing for the fabrics which were dyed by
direct dyes .we increased
the molecular weight after absorbing it on the cellulosic fiber and the
result is decreasing the solubility of the dye in water and increasing
the fastness to washing and rubbing . and after that we carried out the washing and friction tests and evaluated the results.
