Abstract

Una composición aditiva para el acabado en húmedo que se usa como un agente de apresto en un proceso de fabricación de papel, comprendiendo la composiciónuna suspensión de dos fases de almidón dilatado,que tiene una sustancia seca de desde aproximadamente el 0,5 a aproximadamente el 30% en peso, un volumendilatado cocido de desde aproximadamente 1,6 ml./gramo a aproximadamente 100 ml./gramo, y solubles cocidos desde alrededor de 0,5% a alrededor del 50% enpeso. Además, se dan a conocer métodos para elaborar dicha composición partiendo de una suspensión de almidón que tiene una concentraciónrelativamente baja (sustancia seca) de almidón. La suspensión se somete a condiciones de dilatación cuidadosamente controladas (temperatura y pH), quepueden variar de acuerdo al tipo de almidón empleado. La sustancia seca de la suspensión también puede variar de acuerdo a si se emplea un proceso contínuo opor lotes. También se da a conocer un método para aprestar papel con dichacomposición aditiva para la fabricación de papel agregándola al suministrodespués de la etapa de refinación, y un producto (papel aprestado) obtenido por medio de dicho método.A wet finish additive composition that is used as a sizing agent in a papermaking process, the composition comprising a two-phase suspension of dilated starch, having a dry matter of from about 0.5 to about 30% by weight, a boiled volume volume of from about 1.6 ml / gram to about 100 ml / gram, and cooked solubles from about 0.5% to about 50% by weight. Furthermore, methods are disclosed for making such a composition starting from a starch suspension having a relatively low concentration (dry substance) of starch. The suspension is subjected to carefully controlled expansion conditions (temperature and pH), which can vary according to the type of starch used. The dry substance of the suspension can also vary according to whether a continuous batch process is used. Also disclosed is a method of sizing paper with such an additive composition for papermaking by adding it to the supply after the refining step, and a product (sizing paper) obtained by said method.
