Abstract

SEGUN ESTA INVENCION SE PRESENTA UN PROCEDIMIENTO PARA LA REPREPARACION DE FIBRAS CONTENIENDO CELULOSA COMO POR EJEMPLO PAPEL VIEJO PARA LA UTILIZACION EN CUERPOS ABSORVENTES PARA PRODUCTOS MEDICINALES O HIGIENICOS COMO PAÑALES, INSTALACIONES ABSORVENTES, PAÑUELOS HIGIENICOS COMPRESAS, TAMPONES, ETC. POR ESTE MOTIVO LAS FIBRAS SECUNDARIAS SON LLEVADAS A UNA SUSPENSION ACUOSA Y SE TRATA CON LA SUPERFICIE DE LA FIBRA DISGREGADA, ESPECIALMENTE DESINFECTADA QUIMICAMENTE, PREFERENTEMENTE POR AÑADIDURA DE OXIGENO. UNA ACCION DE BENOTITA AUMENTA EL PODER ABSORVENTE DE LA FIBRA SECUNDARIA. EL DESCUBRIMIENTO SE REFIERE ADEMAS A LA APLICACION DE ESTA FIBRA SECUNDARIA REPREPARADA EN CUERPOS DE ABSORCION PARA PRODUCTOS MEDICINALES O HIGIENICOS.
