Process for making a flowable and meterable densified fiber particle
First Claim
Patent Images
1. A process for producing a readily dispersible, flowable, and meterable cellulosic product consisting essentially of:
- singulating cellulose fibers derived from softwood by introducing never dried pulp fibers into a jet drier and drying and singulating the pulp fibers therein to form a mass consisting essentially of dried, singulated cellulose fibers anddensifying the mass of dried singulated fibers and forming the fibers into discrete particles, each of said discrete particles consisting essentially of a plurality of dried, singulated cellulose fibers and that are mechanically bonded together, said particles dispersing into singulated fibers in less than one minute with agitation.

Abstract
Discrete particles of cellulosic material are flowable and meterable. They are easily dispersible in an aqueous or a dry medium. The particles comprise singulated cellulose fibers that have been densified. The particles have a density of at least 0.3 g/cc.
