Once retired, he finally had the time to explore, from a purely scientific perspective, the issue of cellulose cationization processes and its further coloring with reactive dyes.
To complete Mr. Stanisław's doctoral dissertation was no mean feat, as he needed to harness the peculiarities of research work, and if that was not enough, he also needed to reconcile that challenge with his usual duties as a Grandpa. Yet, something that might have been an insurmountable hurdle for his peers ended up becoming a source of strength for him. As the supervisors of Stanisław Pruś' doctoral dissertation, we are filled with admiration for his enthusiasm, determination, and extraordinary energy with which he completed task after task and stage after stage towards the goal he had set for himself.
Environmentally friendly dyeing
The results of dr Stanisław Pruś' research are very interesting and contribute a great deal of knowledge. One of the focuses of his work was on the process of cationization of cellulose, i.e., modification of the surface of the fiber with chemical compounds that change the surface charge and enable more efficient bonding with reactive dyes. Not only does the method make it possible to dye at much lower temperatures, i.e., more economically, but it is also more environmentally friendly due to a significant reduction of chemical compounds required for the dyeing process. An important scientific contribution of the doctoral dissertation is that a mechanism of the bonding reaction of the dye with the modifier was proposed and proven.
The results of his work have been published in several, relatively high IF scientific journals. They have already been noticed by the scientific community, which is demonstrated with a high number of citations. The publications have opened the way for further research and given further stimulus to developing sustainable textile manufacturing technologies.
We are of the opinion that for dr Pruś the message that it is never too late to learn something new and contribute to a better tomorrow is no less important than earning a doctoral degree. Mr. Stanisław is a living proof of the claim that passion and determination can indeed transmute dreams into tangible outcomes.
