摘要： A process for bleaching chemical pulp for paper manufacturing comprising delignifying and bleaching chemical pulp which has been treated by cooking by simultaneous use of chlorine dioxide, a peroxide, and at least one reaction catalyst selected from the group consisting of oxoacids of elements of Groups IV, V and VI and salts of these acids. Formation of organic chlorine compounds as by-products is suppressed by decreasing the amount of chlorine dioxide used in the ECF bleaching process in the first stage, and thus environmental toxicity in the waste water discharged from the bleaching process is decreased. Chemical pulp having a high degree of brightness is economically produced because increase in the production capacity is not required at all or suppressed to the minimum, and the investment cost is reduced to the minimum when the bleaching with chlorine in the first stage is converted into the bleaching with chlorine dioxide which is an ECF bleaching process.

摘要： Provided are a method for producing bleached pulp, comprising processing unbleached pulp obtained by cooking a lignocellulose substance, for alkali-oxygen bleaching followed by treatment with peroxomonosulfuric acid and thereafter by multistage chlorine-free bleaching treatment starting from chlorine dioxide treatment; a method for producing bleached pulp, comprising processing the unbleached pulp for alkali-oxygen bleaching followed by chlorine-free bleaching treatment or totally chlorine-free bleaching treatment to bleach it to a degree of brightness of from 70 to 89%, and further followed by treatment with peroxomonosulfuric acid; and paper produced by the use of the bleached pulp produced according to these production methods, at a papermaking pH of at most 6. Provided are the efficient production methods for bleached pulp in which the colour reversion resistance is enhanced in chlorine-free bleaching and the bleaching cost increase is prevented, and the paper produced by the use of the bleached pulp according to an acid papermaking process.
摘要翻译：本发明提供漂白纸浆的制造方法，其特征在于，对由木质素纤维素物质进行蒸煮而得到的未漂白纸浆进行碱氧漂白处理，然后用二氯甲烷处理开始进行多级无氯漂白处理，一种漂白纸浆的制造方法，其特征在于，对未漂白的纸浆进行碱氧漂白处理，然后进行无氯漂白处理或全部无氯漂白处理，将其漂白至亮度为70〜89％用次氯酸处理; 以及通过使用根据这些生产方法生产的漂白纸制成的纸，造纸pH值至多为6.提供了在无氯漂白中提高耐逆色性的漂白纸浆的有效生产方法。防止漂白成本增加，并且根据酸性造纸方法使用漂白纸浆生产纸。
