Process for the production of an impregnated wood piece, impregnated wood piece obtainable by such a process and pencil having a sheath made of such an impregnated wood piece

A process for the production of impregnated wood pieces for use in pencil production, and pencils with shafts including such impregnated wood pieces, wherein the process comprises two process stages, namelya) a first process stage, comprisinga first impregnation step, in which an untreated wood piece is at least partially, impregnated with a first aqueous impregnating solution of an impregnating agent selected from the group consisting of 1,3-dimethylol-4,5-dihydroxyethylene urea or a derivative or modification thereof, and a catalyst, anda subsequent curing step, in which the impregnated wood piece is cured in a hot steam atmosphere at an elevated temperature above 100° C., andb) a second process stage comprising a second impregnation step, whereby the impregnated, cured wood piece is at least partially impregnated with a second aqueous impregnating solution of a wax emulsion paraffin based as an impregnating agent.
