Abstract

Fibrous structures of the present disclosure may comprise discrete cells comprising one or more legs and/or one or more concavities in certain patterns or Cell Groups. The cells may be discrete knuckles or pillows and may comprise a saddle and at least two legs, where the plurality of discrete wet-formed cells may have a Cell Width, a Saddle Height, a Saddle Width, a Leg Length and a Leg Width, and where the pillow surface has a Distance Between Saddles, a Distance Between Cells, a First Leg Separation Distance, and a Second Leg Separation Distance. A ratio of a Leg Length to a Saddle Height may be between about 1.10 and about 24.0. A ratio of a Distance Between Cells to a Leg Separation Distance may be between about 0.200 and about 10.5.

Claims (30)

1 . A fibrous structure comprising a plurality of discrete wet-formed knuckles extending from a pillow surface of the fibrous structure, wherein each of the plurality of discrete wet-formed knuckles comprises a saddle and at least two legs, wherein the plurality of discrete wet-formed knuckles have a Cell Width, a Saddle Height, a Saddle Width, a Leg Length and a Leg Width, and wherein the pillow surface has a Distance Between Saddles, a Distance Between Cells, a First Leg Separation Distance, and a Second Leg Separation Distance, wherein:

a. a ratio of a Leg Length to a Saddle Height is between about 1.10 and about 24.0, and

b. a ratio of a Distance Between Cells to a Leg Separation Distance is between about 0.200 and about 10.5.
