Abstract
Cellulosic pulps of selected fiber morphology are disclosed having a coarseness less than a threshold coarseness level. The threshold coarseness level is a function of average fiber length. The cellulosic pulps are especially useful for producing paper structures such as tissue paper. A method for producing the cellulosic pulps is also disclosed.
Claims8
A cellulose pulp having improved softness potential, said pulp comprised of wood fibers, the pulp containing at least ten percent softwood fibers and the pulp having a fiber incremental surface area less than 0.085 square millimeters and a fiber coarseness that is related to the average fiber length by the relation:
- C<(L).sup.0.3 +0.3
- wherein C is the fiber coarseness measured in milligrams of fiber weight per 10 meters of fiber length, and L is the average fiber length in millimeters, and wherein L is between about 0.70 millimeter and about 1.1 millimeter.
