Abstract

Process makes a raw cotton linter matted sheet by dispersing a loose mass of raw cotton linters in water, removing a portion of the water from the dispersed loose mass, and pressing the wet loose mass of raw cotton linters into a resulting matted sheet. The loose mass of raw cotton linters can be precleaned before dispersing into water. The final sheeted product can be cut into water. The final sheeted product can be cut into rectangle pieces or wound on a roll or dried or calendered. This sheet is used as a starting material for making cellulose ethers.
