Abstract

Esto permite mayor rendimiento de fibra y economía de fabricacion. Reivindicacion 1: Un método para preparar una pulpa Lyocell que comprende las etapas de proveer una pulpa no blanqueada; en donde dicha pulpa tiene una IV de desde 10 a 5 dl/g; poner en contacto dicha pulpa en una secuencia de blanqueado; en donde dicha secuencia de blanqueado tiene al menos una etapa de un tratamiento con enzimas; en donde dicha secuencia de blanqueado que tiene al menos un tratamiento con enzimas reduce dicha pulpa de 8 a 2 unidades de IV; y en donde dicha pulpa blanqueada es adecuada para la fabricacion de Lyocell.This allows greater fiber performance and manufacturing economy. Claim 1: A method of preparing a Lyocell pulp comprising the steps of providing an unbleached pulp; wherein said pulp has an IV of from 10 to 5 dl / g; contacting said pulp in a bleaching sequence; wherein said bleaching sequence has at least one stage of an enzyme treatment; wherein said bleaching sequence having at least one enzyme treatment reduces said pulp from 8 to 2 units of IV; and wherein said bleached pulp is suitable for the manufacture of Lyocell.
