摘要： The present invention relates to a process for preparing a bleached sulfite chemical pulp comprising:
delignification of chips of a lignocellulosic material in a sulfite pulping process beyond the defibration point of said material until kappa values of below 50 are reached, and
bleaching of the fibrous material thus obtained by means of a chlorine-free bleaching sequence which comprises at least one first bleaching step with a chlorine-free oxidant in the presence of a base.
The chemical pulp prepared according to this process and paper or nonwoven made from such are characterized by a high degree of brightness (at least 83%, in particular more than 86%) and high strength.摘要翻译： 本发明涉及一种用于制备漂白亚硫酸盐化学纸浆，其包括：的木质纤维素材料的芯片脱木素在亚硫酸盐制浆过程超过所述材料的解纤点直到低于50卡伯值被达到，并且该纤维材料的漂白 通过包括在碱的存在下，游离氯氧化剂的至少一个第一漂白步骤无氯漂白顺序的方式将由此获得的。 的化学纸浆制备寻求通过高亮度度数（至少83％，特别是人数超过86％）和高强度的特点由雅丁这一进程，纸或无纺布。
