Abstract

SE PRESENTA UN METODO PARA ABRIR FIBRAS. PREFERENTEMENTE, LAS FIBRAS SE ABREN EN LA PRODUCCION A ALTA VELOCIDAD DE BOBINAS PESADAS-LIGERAS UNIFORMES POR COLOCACION GRADA DE AIRE DE FIBRAS TEXTILES. EN UNA REALIZACION PREFERIDA, UN RODILLO DISPERSOR DENTADO GIRATORIO SE USA PARA ABRIR Y CARDAR FIBRAS DENTRO DE UNA CORRIENTE DE AIRE DE ALTA VELOCIDAD UNIFORME Y BAJA TURBULENCIA PARA FORMAR UNA CORRIENTE FINA DE FIBRA A PARTIR DE LA CUAL LAS FIBRAS SE DEPOSITAN BOBINADAS SOBRE UNA PANTALLA MOVIL. UNA PLACA DISPERSORA CURVADA ENVUELVE EL RODILLO DISPERSOR Y EVITA LA CARDA PREMATURA. AL USAR UNA PLACA DISPERSORA ESPECIFICA QUE TIENE UNA LONGITUD DE ALMA EXPUESTA ENTRE 0.01 A 0.20 PULGADAS Y UNA SEPARACION DE ALMA ENTRE 0.15 A 2.0 PULGADAS, LA CALIDAD DE ALMA SE MEJORA DRAMATICAMENTE DEBIDO AL NUMERO SIGNIFICATIVAMENTE MAS BAJO DE DEFECTOS QUE PERMANECEN EN EL ALMA COMO PEDACITOS DE FIBRA NO ABIERTOS.
