    • Pulp fibers can be treated-'with water insoluble chemical additives resulting in a minimal amount of unretained water insoluble chemical additives present after exposing the treated pulp fibers to process water, liquids, or solutions used in products. One embodiment of the present invention is a method for preparing chemically treated pulp fiber. A fiber slurry is created comprising process water and pulp fibers. The fiber slurry is transported to a web-forming apparatus of a pulp sheet machine thereby forming a wet fibrous web. The wet fibrous web is dried to a predetermined consistency thereby forming a dried fibrous web. The dried fibrous web is treated with a water insoluble chemical additive thereby forming a chemically treated dried fibrous web containing chemically treated pulp fibers. The chemically treated pulp fibers have an improved level of chemical retention of the water insoluble chemical additive and retain from between about 25 to about 100 percent of the applied amount of the water insoluble chemical additive when the chemically treated pulp fibers are exposed to a liquid, such as water. The chemically treated pulp fibers are used to form a fibrous non-woven material.
    • 可以使用水不溶性化学添加剂处理纸浆纤维,导致在处理的纸浆纤维暴露处理产品中使用的水,液体或溶液之后,存在的最少量未溶解的水不溶性化学添加剂。 本发明的一个实施方案是一种制备化学处理的纸浆纤维的方法。 产生包括工艺水和纸浆纤维的纤维浆料。 纤维浆料被输送到纸浆片机的卷筒纸形成装置,从而形成湿纤维网。 将湿纤维网干燥至预定的稠度,从而形成干燥的纤维网。 干燥的纤维网用不溶于水的化学添加剂处理,从而形成经化学处理的干燥纤维网,其含有经化学处理的纸浆纤维。 化学处理的纸浆纤维具有改善的水不溶性化学添加剂的化学保留水平,并且当化学处理的纸浆纤维暴露于液体时,保留施用量的不溶于水的化学添加剂的约25至约100% 如水。 化学处理的纸浆纤维用于形成纤维无纺材料。
