    • A paper with a reduced content of a fluorescent whitening agent and a manufacturing method thereof are provided to separate a remaining content of a fluorescent whitening agent from a paper and remove the remaining content by green technology using enzymes. In a method for manufacturing a paper with a reduced content of a fluorescent whitening agent, an endosperm layer is separated from raw material pulp in a pulper and/or a beater while carrying out hydrolysis for an endosperm layer containing a fluorescent whitening agent by adding enzymes such as amylase, cellulase, xylanase, and mixture thereof to the raw material pump, wherein the raw material pulp is treated with the endosperm layer. Impurities are removed from the beaten raw material pulp through a cleaner and/or a screen, so that perfect pulp stuff is screened from the raw material pulp. The pulp stuff is compressed, dried and wound on a winder.
    • 提供具有降低的荧光增白剂含量的纸及其制造方法,以从纸中分离荧光增白剂的剩余量,并通过使用酶的绿色技术除去剩余的含量。 在制造荧光增白剂含量降低的纸的方法中,在碎浆机和/或打浆机中将胚乳层与原料纸浆分离,同时通过添加酶对包含荧光增白剂的胚乳层进行水解 例如淀粉酶,纤维素酶,木聚糖酶及其混合物,其中原料浆用胚乳层处理。 杂质通过清洁剂和/或筛网从被打浆的原料纸浆中除去,从而从原料纸浆中筛选出完美的纸浆。 纸浆被压缩,干燥并卷绕在卷绕机上。
