Abstract
Inventia se refera la procedeu si un dispozitiv de obtinere a fibrelor scurte, prin supunerea detentiei a unui amestec bifazic, format din polimer topit si solvent, care se gasesc la presiune si temeperatura ridicata, prin injectiea printr-un orificiu astfel încat solventul si polimerul sa se solidifice, scurgerea amestecului bifazic fiind perturbata în momentul în care patrunde în orificiul de detenta, dispozitivul fiind prevazut cu o cama de perturbare cu cel putin un orificiu de alimentare si în partea opusa cu un orificiu de detenta.The invention relates to a process and apparatus for obtaining short fibers by subjecting the detention of a biphasic mixture consisting of molten polymer and solvent which are under pressure and high temperature by injection through an orifice such that the solvent and its polymer solidifies the leakage of the biphasic mixture as it penetrates into the detent port, the device being provided with a disruption cam with at least one supply port and, on the opposite side, with a detent port.
