Abstract

La presente invención se refiere a un procedimiento mejorado para la fabricación de papel que contiene alumbre y un derivado de almidón modificado, caracterizado porque comprende agregar, como un auxiliar de retención del pigmento a la materia prima que contiene más del 4 por ciento de alumbre con base en el peso de la pulpa seca, en cualquier etapa antes de formar una tela, un derivado de almidón de un almidón no gelatinizado que tiene una fluidez en agua entre 4 y 40, dicho derivado de almidón contiene grupos sulfo-succinatos introducidos químicamente y nitrógeno cationogénico o catiónico que contiene grupos substituyentes seleccionados del grupo que consiste de aminas primarias, secundarias y terciarias y grupos amonio cuaternarios, en donde el grado de substitución en dicho derivado de almidón es de alrededor de 0.008 a 0.20 con respecto a los grupos sulfo-succinatos y alrededor de 0.005 0.50 con respecto al nitrógeno que contiene grupos substituyentes, dicho derivado de almidón siendo agregado a la materia prima en una cantidad de alrededor de 0.05 a 2.0 por ciento en peso con base en el peso de la pulpa seca.The present invention relates to an improved process for the manufacture of paper containing alum and a modified starch derivative, characterized in that it comprises adding, as a pigment retention aid, to the raw material containing more than 4 percent alum with based on the weight of the dried pulp, at any stage before forming a fabric, a starch derivative of a non-gelatinized starch having a fluidity in water between 4 and 40, said starch derivative contains chemically introduced sulfo-succinate groups and cationogenic or cationic nitrogen containing substituent groups selected from the group consisting of primary, secondary and tertiary amines and quaternary ammonium groups, where the degree of substitution in said starch derivative is around 0.008 to 0.20 with respect to the sulfo groups. succinates and about 0.005 0.50 with respect to nitrogen containing substituent groups, said starch derivative if Endo added to the raw material in an amount of about 0.05 to 2.0 weight percent based on the weight of the dried pulp.
