Abstract

SE DESCRIBE UN HILADO DE UNA DISOLUCION DE ALCOHOL POLIVINILICO ACUOSO, QUE CONTIENE ACIDO BORICO EN UN BAÑO DE COAGULACION ALCALINO. EL BAÑO DE COAGULACION SE MANTIENE A UNA TEMPERATURA DE 55-95 (GRADOS) C. LA ESTOPA DE MONOFILAMENTOS RESULTANTE ES ESTIRADA A UNA RELACION DE ESTIRAMIENTO NO MENOR QUE 7. ESTE PROCEDIMIENTO PROPORCIONA FIBRAS SINTETICAS A BASE DE ALCOHOL POLIVINILICO, QUE TIENEN UNA CONFIGURACION DE SECCION TRANSVERSAL LIMITADA Y PROPIEDADES MECANICAS SUPERIORES. UTILIZANDO ESTAS FIBRAS COMO MATERIAL DE REFUERZO DE RESINAS, CAUCHOS, METERIALES HIDRAULICOS, ETC, SE PUEDEN OBTENER OBJETOS CONFORMADOS QUE TIENEN PROPIEDADES MECANICAS MEJORADAS.A YARN IS DESCRIBED OF A SOLUTION OF AQUEOUS POLYVINYL ALCOHOL, CONTAINING BORIC ACID IN AN ALKALINE COAGULATION BATH. THE COAGULATION BATH IS MAINTAINED AT A TEMPERATURE OF 55-95 (DEGREES) C. THE RESULTING MONOFILAMENT STOP IS STRETCHED AT A RATIO OF STRETCHING NOT LESS THAN 7. THIS PROCEDURE PROVIDES SYNTHETIC FIBERS BASED ON POLYVINYL ALCOHOL, WHICH HAVE A OF LIMITED CROSS SECTION AND SUPERIOR MECHANICAL PROPERTIES. USING THESE FIBERS AS RESIN REINFORCEMENT MATERIAL, RUBBER, HYDRAULIC METERIALS, ETC, YOU CAN OBTAIN CONFORMED OBJECTS THAT HAVE IMPROVED MECHANICAL PROPERTIES.
