Abstract

La presente invención se refiere a un proceso mejorado para hilado rápido de cuerdas o cabos de filamento-fibrilla plexifilamentarias, caracterizado porque se disuelve polietileno en un líquido de halocarburo para hilado, para formar una solución para hilado que contiene 10 a 20 por ciento de polietileno por peso de la solución a una temperatura en el rango de 130 a 210 grados C y una presión que es más grande que 211.11 Kg/cm cuadrado (3000 psi), tal solución es hilada rápidamente en una región substancialmente de temperatura y presión bajas, la mejora está caracgterizada porque el halocarburo se selecciona del grupo que consiste de: 1,1-dicloro-2,2,2-trifluoroetano y 1,2-dicloro-1,2,2-trifluoroetano.The present invention relates to an improved process for rapid spinning of plexifilamentary filament-fibril cords or strands, characterized in that polyethylene is dissolved in a halocarbon spinning liquid to form a spinning solution containing 10 to 20 percent polyethylene by weight of the solution at a temperature in the range of 130 to 210 degrees C and a pressure that is greater than 211.11 Kg / square cm (3000 psi), such a solution is quickly spun in a region of substantially low temperature and low pressure, the improvement is characterized in that the halocarbon is selected from the group consisting of: 1,1-dichloro-2,2,2-trifluoroethane and 1,2-dichloro-1,2,2-trifluoroethane.
