The present invention relates to 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, namely a) a first process stage, comprising a 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, and a subsequent curing step, in which the impregnated wood piece is cured in a hot steam atmosphere at an elevated temperature above 100° C., and b) 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.

Each of a set of knitting needles have a length correlated to at least two factors (e.g., needle diameter, and yarn weight) to provide appropriate strength, stability, and suitable take-up for stitches created during the knitting process. The correlation is such that as needle diameters (D) grow, and/or the yarn weight increases, the needle length grows in a particular relation, as follows: $L=\frac{\left(W+2\right)\left(15D+15\right)}{\left(\mathrm{.4}W+2\right)\left(\mathrm{.9}D+5\right)}$
where “L” is the length of the needle, “D” is the needle diameter, and “W” is the yarn weight from 0 to 7 (i.e., lace=0, super fine=1, fine=2, light=3, medium=4, bulky=5, super bulky=6, and jumbo=7). Raw wood for the needle is stabilized in a process including application of a composition that is maintained thereon for a period of time and in a vacuum, and heat treatment.

The invention relates to a method for preparing a densified wood article comprising vacuum impregnating a porous low-density type of wood with a specified aqueous phenolformaldehyde resin composition and pressing. The invention also relates to a densified wood article obtainable by the process having a low set-recovery. The invention further relates to the use of an aqueous phenol-formaldehyde resin composition for impregnation of wood for impregnating wood in a process for the manufacture of densified wood articles and to the use densified wood articles in high value-added applications like flooring or furniture and for machine tooling applications.
