A process is provided for treating wood products including lumber, plywood and other engineered wood products comprising the steps of contacting a composition comprising a polypropylene glycol, a high molecular weight polyethylene glycol, a polyether polyol having low solubility in water, or a polytetrahydrofuran, or hydrophobic polyether polyol, with the wood product. The invention also provides wood products comprising a polypropylene glycol, a high molecular weight polyethylene glycol, a polyether polyol having low solubility in water, or a polytetrahydrofuran, or hydrophobic polyether polyol, that have greater dimensional stability compared to an untreated wood product.

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:

[00001]$L=\frac{\left(W+2\right).Math..Math.\left(15.Math.D+15\right)}{\left(\mathrm{.4}.Math..Math.W+2\right).Math.\left(\mathrm{.9}.Math.D+5\right)}$

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.

A crosslinking polyvinyl acetate (XPVAc or X-PVAc) adhesive is applied as a primer (i.e., a basecoat) or an exterior coat (i.e., a top coat) on a wood preservation product which is mainly treated with a water-based preservative. By sealing the exterior wood surfaces, the new coating system not only effectively prevents the leaching of the preservative by bonding and chelating with the unfixed preservative compounds or complexes at the surface layer, but it also significantly reduces surface aging of wood, maintains effective preservation functions, and provides a longer service life to the wood preservation product.

The present invention relates to furniture panels, and more particularly, to a method for preparing functional engineered wood. It includes the following steps: make veneer blanks by rotary cutting or splicing, and cut the veneer blanks into desired dimensions to obtain veneers A. Soak the veneers A in a ternary mixed solution of a biomass nanocellulose solubilizer, a fire retardant and an acid dye for toughening, fire retardation and dyeing to obtain veneers B. Add a formaldehyde decomposing powder into a modified MUF adhesive, mix them up, coat the veneers B with the mixture to obtain veneers C. Assemble and cold-press the veneers C to obtain flitches D, and saw the flitches D into desired patterns and dimensions to obtain finished products.

The invention relates to a method for treatment of wood material. In a first treatment step comprises the provision of a solution comprising zinc oxide or titanium(IV) isopropoxide and immersion of the wood material into the solution. After drying of the wood material a second treatment step is following in case of the first solution comprising zinc oxide. The second treatment step comprises the provision of a solution comprising a zinc compound and immersion of the wood material from the first treatment step into the solution followed by drying of the wood material. In a second aspect the invention relates to a wood material characterized by the visibility of the natural appearance of the surface and at least one other property relating to UV resistance, weathering resistance, mechanical resistance or hydrophobic properties.

In a process for the production of a flame retardant and/or strengthened fiberboard, a tailored fiberboard is charged on a processing device at first. Subsequently, a flame retardant and/or strengthening agent is applied to the top side of the fiberboard. The agent applied is sucked or pressed into the fiberboard. This is achieved by generating a pressure difference between the top side and bottom side of the fiberboard.

The present disclosure describes a treated cellulosic material comprising: a cellulosic material having a porous structure defining a plurality of pores, at least a portion of the pores containing a treating agent comprising: a polymer comprising an olefin-carboxylic acid copolymer; and a modifying agent comprising a hydrophobic amine.

Wooden articles such as toothpicks, stir sticks, skewers and chopsticks made from substrate wood that has been impregnated with spirit liquid or vapor. The substrate may come from spirit producing barrels or from other wood involved in the spirit making process.

A heat insulation material is provided that is produced by drying a fibrous matrix impregnated with a solution of pseudo-peptides of formula (I), wherein: R is a side-chain of a natural or synthetic amino acid, R1 is either a linear or branched (C.sub.1-C.sub.3)alkyl group, or a linear or branched (C.sub.1-C.sub.3)alcoxy group, or an aryl group, or an aryl(C.sub.1-C.sub.3)alkyl group, or an aryloxy group, or a saturated or unsaturated heterocycle, n=1 or 2, and A is an aromatic or heteroaromatic group with at least one cycle.

The present disclosure relates, according to some embodiments, to methods and systems for impregnating wood with a polymer solution and products thereof. In some embodiments, the present disclosure relates to a method of processing a wood piece to generate a wood product, the method comprising: (a) placing the wood piece into a reactor having a chamber pressure of a vacuum environment; (b) exposing the wood piece to a polymer solution; (c) performing an iterative process where each cycle of the iterative process comprises a pressurizing period during which the chamber pressure is increased to an increased chamber pressure and a stabilizing period during which the chamber pressure is monitored to measure a chamber pressure decrease, if any; (d) when the decrease of chamber pressure during the stabilizing period is less than or equal to the certain threshold change, normalizing the reactor chamber to a normalized pressure; and (e) setting the wood piece to generate the wood product. The present disclosure further relates to a wood product generated by a method of processing a wood piece.
