Dried singulated crosslinked cellulose pulp fibers
Abstract
The present invention provides a dried product having singulated, crosslinked cellulose pulp fibers, and an apparatus and method for making singulated, crosslinked, and dried fibers. In accordance with the method, a feed pulp containing a crosslinker is fed to a jet dryer. The nozzle dryer separates and dries the feed pulp. The singulated and dried fibers are recovered from the jet dryer. The feed pulp may also be treated with a treatment substance. The nozzle dryer can be kept at negative pressure. The product fibers can have a low knot count, a low tonnage of fine denierconstituents as well as improved values of entanglement, crimping and hanking. The apparatus for carrying out the method may include: a pretreatment station for supplying the treatment substance, a pulp-fed pulp supply device, a pulp supply device designed for pulp and foam suspensions, and / or a fiber separator Station, which has a vacuum conveyor.
