| Résumé : |
One of the most important parameters for acrylic fibers is tenacity, which is a basic customer demand in the textile industry. There are different methods to increase tenacity in co-polymer preparation (increasing solid percentage in dope, changing in viscisity etc.) and in spinning operation (changing the operating condition of coagulation bath, dryer etc.). But in an industrial, mass, steady production process there are serious limitations. In this article, the effect of determining parameters especially final stretch, shrinkage and coagulation in industrial production process to reach improved tenacity is investigated. The process in Acrylic II factory of Polyacryl Company is based on solution polymerization with DMF as solvent followed by wet spinning method to produce fibers. |
