p. 253 - 264 CONSIDERATIONS SUR LE POSSIBILITES D'UTILISATION DES FILS TECHNIQUES DE FEUILLE FIBRILLEE DE POLYPROPYLENE A LA CONFECTION DES CHALUTS Viorica Boghici et N. Uzun Institut Roumain de Recherches Marines Constanta Abstract The paper presents experiments carried out with the fibrillated polypropylene twines and ropes, comparing their characteristic feautures with those of the polyamide and polyester materials, generally used now. Their behaviour in the industrial fishery pointed out that fibrillated polypropylene may be used like heavy ropes (bellylines) only, in the trawls construction.
