A drying system including jet drier for making dried singulated crosslinked cellulose pulp fibers

摘要

A drying system for the processing of pulp into singulated and dried fibers comprising: a jet drier with a jet conduit, a pulp intake for delivery of pulp into the jet conduit, a manifold for air intake into the jet conduit, and a fiber outlet for removal of singulated and dried fibers, outlet air and fines from the jet conduit; a pulp supply station coupled to the pulp intake for supplying a feed pulp to the pulp intake, the pulp supply station including a treatment supply source for delivering a crosslinker such as polyacrylic acid, glyoxal, malic acid or tartaric acid to the pulp; an air supply station coupled to the manifold for delivering air to the manifold; an outlet flow conduit coupled to the fiber outlet for the removal of the fibers, outlet air, and fines from the jet conduit; and a fiber separation station coupled to the outlet flow conduit for separating the fibers from the outlet air is disclosed. Dried singulated cellulose pulp fibers produced by the above drying system have low knot count, a low fines count, as well improved knit, curl and twist and are useful for a wide product range from absorbent personal articles to a reinforcer in concrete.
