Abstract

PROCEDIMIENTO DE OBTENCION DE FIBRAS E HILOS HIGROSCOPICOS DE SECCION ESTABLE A SU POSTERIOR ELABORACION A ESTRUCTURAS TEXTILES, Y CON ESTRUCTURA DE NUCLEO-ENVOLVENTE. SE PARTE DE POLIMEROS HIDROFOBOS, OBTENIENDOSE UNAS FIBRAS HIGROSCOPICAS DE SECCION REDONDA U OVALADA Y DE ESTRUCTURA DE NUCLEO-ENVOLVENTE, SEGUN UN PROCESO DE HILADO EN SECO, EN EL QUE SE AÑADE AL DISOLVENTE DE HILADO UNA SUSTANCIA (B) CON UN PUNTO DE EBULLICION SUPERIOR AL DEL DISOLVENTE, MUY SOLUBLE EN EL Y EN AGUA Y NO DISOLVENTE PARA EL POLIMERO A HILAR. PREVIAMENTE EL PROCESO DE HILADO HAY QUE AÑADIR AL POLIMERO UNA SUSTANCIA (A) SOLUBLE EN LA SUSTANCIA (B) ANTERIOR Y DURANTE LA SOLIDIFICACION DEL HILO, COMO GLICOL, Y SOLUBLE EN EL DISOLVENTE DE HILADO, COMO DMF, QUE SEA INSOLUBLE EN AGUA Y QUE NO SE EVAPORE EN EL PROCESO DE HILADO. EL POLIMERO PUEDE SER DE LA SERIE DE LOS POLICARBONATOS, POLIESTIRENOS, AFETATOS DE POLIVINILO Y DERIVADOS DE CELITA.
