摘要： 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.

摘要： A synergistic aqueous wood preservative composition comprising a copper compound and penflufen. The copper compounds of the compositions of the invention may be soluble, partially solubilized or micronized particles. The penflufen of the compositions of the invention may be solubilized, emulsified or particulate. The wood preservative compositions of the present invention are surprisingly provided as stable dispersions and confer surprising and unexpected resistance to treated wood and wood products.

摘要： 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 = ( W + 2 )   ( 15  D + 15 ) ( .4   W + 2 )  ( .9  D + 5 ) 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.

摘要： The present invention describes a process of improving the dimensional stability of wood and a dimensionally stable wood thereof. The said process is governed by contacting a composition comprising resin, catalyst and dye with a wood in a closed container followed by evacuating the air from the chamber and creating a vacuum. It is further treated with a composition comprising resin and dye followed by vacuum treatment during the contact step for at least 2 hours followed by a resting period and further treated in a temperature of approximately 100 degrees Celsius for about 1 hour and 30 minutes in order to obtain the desired wood.

摘要： Wood markers and processes for durably marking and subsequently identifying both original grain wood products and wood-plastic composite products. The wood marker can be dispersed beneath the surface of the wood, where it is protected from the elements and may endure years of exposure to the elements. The wood marker is compatible with state-of-the-art pressure-treating processes and may subsequently be detected for authentication purposes by known analytical methods.
