    • Pulp fibers can be treated with adsorbable chemicals with a minimal amount of unadsorbed chemical additives present later in the papermaking process water. A method for adding an adsorbable chemical to pulp includes mixing pulp fibers that have never been dried with water to form a fiber slurry. An adsorbable chemical additive is added to the fiber slurry. The fiber slurry having the adsorbable chemical additive is transported to a web-forming apparatus where a wet fibrous web is formed. The wet fibrous web may be dried to a predetermined consistency thereby forming a dried fibrous web having from between about 10 to about 100 percent retention of the adsorbable chemical additive. The dried fibrous web is transported to a paper machine where the dried fibrous web is mixed with water to form a wet slurry. In other embodiments, the fiber slurry can be processed to provide crumb fibers or wet lap fibers. The wet slurry containing the fibers having the adsorbable chemical additive adhered thereto is transported through the paper machine to form a finished paper or tissue product having enhanced quality due to the retention of the adsorbable chemical additive on the pulp fibers.
    • 纸浆纤维可以用可吸附的化学品处理,在造纸工艺水中稍后使用少量未吸附的化学添加剂。 将可吸附化学品添加到纸浆中的方法包括将从未被干燥的纸浆纤维与水混合以形成纤维浆料。 向纤维浆料中加入可吸附的化学添加剂。 具有可吸附化学添加剂的纤维浆料被输送到形成湿纤维网的幅材成形设备。 可以将湿纤维网干燥至预定的稠度,从而形成具有约10至约100%可吸附化学添加剂保留率的干燥纤维网。 将干燥的纤维网输送到造纸机,其中干燥的纤维网与水混合以形成湿浆料。 在其它实施方案中,纤维浆料可以被加工以提供碎屑纤维或湿的沥青纤维。 含有粘附有可吸附化学添加剂的纤维的湿浆料通过造纸机输送,由于可吸附化学添加剂在纸浆纤维上的保留而形成质量提高的成品纸或纸制品。
