  • Description: Disclosed are non-wood pulps having a fiber length greater than about 1.70 mm and a brightness of about 80% or greater. The relatively high degree of brightness is achieved without a loss of fiber length or pulp yield. The high degree of brightness and relatively long fiber length make the pulps well suited for the manufacture of wet-laid fibrous products, particularly wet-laid tissue products. The pulps may be prepared from plants of the family Asparagaceae by mechanical pulping and more preferably by a chemi-mechanical pulping using a sodium hydroxide alkaline peroxide solution where the primary pulp is cleaned to reduce debris prior to bleaching. Preferably the cleaned primary pulp has less than about 5 wt% debris prior to bleaching. Se describen pulpas no leñosas que tienen una longitud de fibra mayor que aproximadamente 1.70 mm y un brillo de aproximadamente 80 % o mayor. El grado relativamente alto de brillo se logra sin una pérdida de longitud de fibra o rendimiento de la pulpa. El alto grado de brillo y la longitud de fibra relativamente larga hacen que las pulpas sean adecuadas para la fabricación de productos fibrosos húmedos, particularmente productos de papel tisú húmedos. Las pulpas pueden prepararse a partir de plantas de la familia Asparagaceae mediante fabricación de pulpa mecánica y, con mayor preferencia, mediante un proceso de fabricación de pulpa quimiomecánico mediante el uso de una solución de peróxido alcalino con hidróxido de sodio donde la pulpa primaria se lava para reducir los desechos antes del blanqueamiento. Preferentemente, la pulpa primaria limpia tiene menos de aproximadamente 5 % en peso de desechos antes del blanqueamiento.
