Fibrous Structures

A fibrous structure is disclosed. The fibrous structure exhibits a plurality of discrete knuckles arranged in a pattern of repeat units. The repeat units can include a plurality of rows arranged orthogonally in an X-Y plane, each row having a portion of the discrete knuckles, and each discrete knuckle separated from adjacent discrete knuckles in a row by a distance. Each of the discrete knuckles within the repeat unit can have substantially the same shape and size; and wherein the distance between at least two adjacent discrete knuckles in each row are non-uniform such that the repeat unit exhibits varying pillow width distances along the rows in both the X and Y axes.

High strength and low stiffness hesperaloe tissue

Soft, durable and bulky tissue products comprising non-wood fibers and more particularly high yield hesperaloe pulp fibers are disclosed. The tissue products preferably comprise at least about 5 percent, by weight of the product, high yield hesperaloe pulp fiber and have relatively modest tensile strengths, such as a geometric mean tensile (GMT) greater than about 1,000 g/3, and improved durability and cross-machine direction (CD) properties, such as a CD Stretch greater than about 10 percent. Additionally, at the foregoing tensile strengths the products are not overly stiff. For example the tissue products may have a Stiffness Index less than about 10.0.

SHEET MANUFACTURING APPARATUS, CONTROL METHOD THEREOF, AND SHEET MANUFACTURING METHOD
20200002894 · 2020-01-02 ·

The sheet manufacturing apparatus includes a fibrillating unit that fibrillates a raw material including fibers in a gas, an additive supply unit that supplies an additive, a mixing unit including a first rotating unit that mixes a fibrillated matter fibrillated by the fibrillating unit and the additive supplied by the additive supply unit, a depositing unit that deposits a mixture mixed by the mixing unit, a web forming unit including a mesh belt that transports a deposited material deposited by the depositing unit and a suction mechanism that sucks the deposited material to the mesh belt, and a control unit that changes granularity of a surface of the sheet by controlling at least one of a supply amount per unit time from the additive supply unit, a rotation velocity of the first rotating unit of the mixing unit, and a suction force of the suction mechanism.

NONWOVEN MATERIAL FOR CLEANING AND SANITIZING SURFACES

Nonwoven materials having at least one layer are provided, as well as their use in cleaning articles. More particularly, the nonwoven materials can include a carrier composition including a binder and a blocking agent. The carrier composition can repel a sanitizing agent, such as a quaternary ammonium compound, from the surface of the nonwoven material in order to facilitate the release of the sanitizing agent from the surface of the nonwoven material.
