Appl. No.:

10/455332

Inventors:

Homan Kinsley - Powhatan VA, US
Donald Moser - Quinton VA, US

International Classification:

D21H017/33
D21H017/28

US Classification:

162/158000, 162/164100, 162/175000

Abstract:

Provided is a low water paper product comprised of wood pulp having at least some of the water present in the amorphous regions of the cellulosic pulp fiber structure replaced with a polyhydroxy polymer. The preferred polyhydroxy polymer used to replace the water is polyvinyl alcohol. The resulting paper product exhibits improved dimensional stability, particularly when exposed to water or water vapor. Characteristics of the paper product make it quite suitable for use in transformers.

Abstract:

Provided is a novel locomotive oil filter for use in locomotive applications. The filter is comprised of a pulp which is comprised of lignin-containing fibers derived from a fiber source having a lignin content of at least about 10% by thermomechanically pulping a fiber source under temperature/pressure conditions of 300. degree. F. -350. degree. F. /50 psig-120 psig and a refiner energy utilization of about 8-35 HPD/ADT. The locomotive oil filter comprising the pulp of such lignin-containing fibers overcomes the severe problems of filter swelling and plugging due to water in the locomotive oil, while also providing one with improved filtration capacity and good filtration. The use of such lignin-containing fiber pulp also gives one the economic advantage of substitution for the more expensive cotton linter generally used heretofore in railroad/locomotive lube oil filters. The pulp of lignin-containing fibers can be used in combination with other suitable pulps, e. g. , high alpha cellulose content pulps, in making the filter media.
