A particle or particles of cellulosic wood pulp fibers having a top and bottom face and a hexagonal perimeter, and methods of using it.
First claim
Opening claim text (preview).
The invention claimed is: 1. A cellulosic wood pulp fiber particle having two opposed faces and a hexagonal perimeter, a major axis length of 4 to 8 mm, a width of 2 to 5 mm and a thickness of 0.1 mm to 4 mm, wherein the wood pulp fiber is in the form of a wood pulp sheet, a paperboard sheet, or a paper sheet, wherein the particle has a basis weight of 70 to 120 g/m 2 . 2. A cellulosic wood pulp fiber particle having two opposed faces and a hexagonal perimeter, a major axis length of 4 to 8 mm, a width of 2 to 5 mm and a thickness of 0.1 mm to 4 mm, wherein the wood pulp fiber is in the form of a wood pulp sheet is in the form of a wood pulp sheet, a paperboard sheet, or a paper sheet, wherein the particle has a basis weight of 100 to 350 g/m 2 . 3. A cellulosic wood pulp fiber particle having two opposed faces and a hexagonal perimeter, a major axis length of 4 to 8 mm, a width of 2 to 5 mm and a thickness of 0.1 mm to 4 mm, wherein the wood pulp fiber is in the form of a wood pulp sheet is in the form of a wood pulp sheet, a paperboard sheet, or a paper sheet, wherein the particle has a basis weight of 350 to 500 g/m 2 .
