    • A process for making a unitary fibrous structure (100) comprises steps of: providing a fibrous web comprising a plurality of cellulosic fibers (110) randomly distributed throughout the fibrous web and a plurality of synthetic fibers (120) randomly distributed throughout the fibrous web; and causing co-joining of at least a portion of the synthetic fibers with the cellulosic fibers and the synthetic fibers, wherein the co-joining occurs in areas having a non-random and repeating pattern. A unitary fibrous structure comprises a plurality of cellulosic fibers randomly distributed throughout the fibrous structure, and a plurality of synthetic fibers distributed throughout the fibrous structure in a non-random repeating pattern. In another embodiment, a unitary fibrous structure comprises a plurality of cellulosic fibers randomly distributed throughout the fibrous structure, and a plurality of synthetic fibers randomly distributed throughout the fibrous structure, wherein at least a portion of the plurality of synthetic fibers comprises co-joined fibers, which are co-joined with the synthetic fibers and/or with the cellulosic fibers.
    • 制备单一纤维结构(100)的方法包括以下步骤:提供包含随机分布在整个纤维幅材上的多个纤维素纤维(110)的纤维幅材和随机分布在整个纤维幅材上的多个合成纤维(120) 并使至少一部分合成纤维与纤维素纤维和合成纤维共同接合,其中共连接发生在具有非随机和重复图案的区域中。 整体纤维结构包括随机分布在整个纤维结构中的多个纤维素纤维,以及以非随机重复图案分布在纤维结构中的多个合成纤维。 在另一个实施方案中,整体纤维结构包括随机分布在整个纤维结构中的多个纤维素纤维,以及随机分布在整个纤维结构中的多个合成纤维,其中多个合成纤维的至少一部分包括共连接纤维 ,其与合成纤维和/或与纤维素纤维共同连接。
