Abstract

LA TENDENCIA A LA FIBRILACION DE LA FIBRA DE CELULOSA HILADA MEDIANTE SOLVENTES PUEDE INCREMENTARSE EXPONIENDO LA FIBRA A UN TRATAMIENTO QUE REDUCE SU GRADO DE POLIMERIZACION EN ALREDEDOR DE 200 UNIDADES O MAS. LOS METODOS ADECUADOS DE TRATAMIENTO INCLUYEN EL BLANQUEADO SEVERO, POR EJEMPLO LA APLICACION DE UN LICOR ACUOSO QUE CONTIENE ENTRE UN 0.1 Y UN 10% DE SU PESO DE HIPOCLORITO DE SODIO (COMO CLORO DISPONIBLE) A LA FIBRA CONTINUANDO CON UN TRATAMIENTO MEDIANTE VAPOR. LA FIBRA PUEDE TRATARSE EN FORMA PREVIAMENTE SECADA O SIN SECAR. LA FIBRA TRATADA MEDIANTE EL PROCESO DE LA INVENCION ES UTIL POR EJEMPLO EN LA MANUFACTURA DEL PAPEL Y DE TEJIDOS HIDROENMARAÑADOS. LA FIBRA DE TENDENCIA INCREMENTADA A LA FIBRILACION PUEDE SER BATIDA HASTA UN CANADIAN STANDARD FREENESS DE 400 EN EL DISINTEGRATION TEST MEDIANTE 30000-150000 REVOLUCIONES DEL DESINTEGRADOR Y HASTA UN CANADIAN STANDARD FREENESS DE 200 EN EL MISMO TEST MEDIANTE 50000-200000 REVOLUCIONES DEL DESINTEGRADOR.
