    • Pulp fibers can be treated with water insoluble chemical additives resulting in a minimal amount of unretained water insoluble chemical additives present after redispersing the treated pulp fibers in the process water. 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 redispersed in water.
    • 纸浆纤维可以用水不溶性化学添加剂处理,导致在将处理过的纸浆纤维再分散在工艺用水中时,存在的最少量的不可水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再分散在水中时,保留约25至约100%的施用量的水不溶性化学添加剂。

    • A tissue product containing a multi-layered paper web that has at least one layer formed from a blend of pulp fibers and synthetic fibers is provided. By containing at least one layer of synthetic and pulp fibers, it has been discovered that lint and slough of a tissue product formed according to the present invention can be substantially reduced. In addition, by limiting the amount and layers to which the synthetic fibers are applied, the increase in hydrophobicity and cost of the tissue product may be minimized, while still achieving the desired reduction in lint and slough. In some embodiments, the tendency of the synthetic fibers to sink or float in the fibrous furnish may be minimized to enhance processability by selecting certain types of synthetic fibers, e.g., those with a certain density imbalance.
    • 提供了一种包含多层纸幅的纸制品,其具有由纸浆纤维和合成纤维的混合物形成的至少一层。 通过含有至少一层合成纤维和纸浆纤维,已经发现可以显着降低根据本发明形成的纸巾产品的绒毛和脱落。 此外,通过限制施用合成纤维的量和层,可以使组织产品的疏水性和成本的增加最小化,同时仍然实现所需的棉绒和脱毛减少。 在一些实施方案中,可以通过选择某些类型的合成纤维(例如具有一定密度不平衡的合成纤维)来使合成纤维沉降或漂浮在纤维配料中的趋势最小化以提高加工性能。
