United States Patent No: US 10,767,314 / Issuance Date: Sept 8, 2020

Methods to reduce sticky and fluff-induced rewinder breaks by reducing the adhesive character of adhesive materials, fluff, and sticky contaminants in fibers are described. One method involves contacting the fibers with a composition containing at least one of each a cellulase, a hemicellulase, a B – glucosidase, a lipase, an esterase, a pectinase, a pectate lyase, and a laccase for a sufficient time and in a sufficient amount to control the removal or controlling adhesive materials, fluff and sticky contaminants present in the fibers. Preferably, the fibers are recycled fibers originating from a variety of sources such as old corrugated containers, old newsprint, mixed office waste, and the like. Resulting paper products formed from the processed fibers are also described as well as methods to make them.
