Abstract:
(EN) The purpose of the present invention is to optimize a bleaching process in a manufacturing process for phosphorylated cellulose fiber. The present invention relates to pulp comprising cellulose fiber having a phosphate group or a phosphate group derived substituent of 0.5 mmol/g or greater, wherein the pulp has ISO whiteness of 82% or greater for four stacked sheets of the pulp. In addition, the b* value in the L*a*b* colorimetric system for four stacked sheets of the pulp is 5.5 or less.
(FR) L'objectif de la présente invention est d'optimiser un processus de blanchiment dans un procédé de fabrication de fibre de cellulose phosphorylée. La présente invention concerne une pâte comprenant une fibre de cellulose possédant un groupe phosphate ou un substituant dérivé d'un groupe phosphate de 0,5 mmol/g ou plus, la pâte possédant une blancheur ISO supérieure ou égale à 82 % pour quatre feuilles empilées de la pâte. De plus, la valeur b* dans le système colorimétrique L*a*b* pour quatre feuilles empilées de la pâte est inférieure ou égale à 5,5.
(JA) 本発明は、リン酸化セルロース繊維の製造工程における漂白プロセスを最適化することを目的とする。本発明は、0.5mmol/g以上のリン酸基又はリン酸基由来の置換基を有するセルロース繊維を含むパルプであって、パルプをシートとし、4枚重ねたもののISO白色度が82%以上であるパルプに関する。また、本発明のパルプをシートとし、4枚重ねたもののL***表色系におけるb*値は5.5以下である。
