Abstract
|
|
|
|
In this thesis, we took some stalks, flowers, and leaves of the Hypericum ascyron L. which are able to propagate as mass in our wild to extract the dyeing solution, and cotton and silk were dyed using them in many different conditions. Silk was dyed darker than cotton with increasing the pH density. Silk was dyed darkest among Hypericum ascyron if pH was neutral. We found there was not a big difference between silk and cotton in the given condition considering ’’Y’’ values vs. dyeing temperature. However cotton was dyed darker in hypericum ascyron. There was a rapid decreasing of ’’Y’’ values after one to two hours and almost all of dyeing was completed at these times. We found there was a dyeing acceleration at the higher dyeing density and the lower ’’Y’’ value. If the density was low, dyeing attachment was reduced by dyeing ability via the density of liquid in this plants. Silk was affected higher by mordant dyes in this plants. Fe and Cu had no effect on Hypericum ascyron.
