Claims
- 1. A process for treating timber, consisting essentially of:
- providing a freshly sawn timber having a high moisture content above a fiber saturation point of the timber,
- immersing the high moisture content timber which has not been subjected to a drving treatment in a first liquid consisting essentially of a first organic solvent compatible with water, and then subsequently without drying,
- immersing the timber in a second liquid consisting essentially of a wood preservative and a second organic solvent which has a boiling point of not less than 150.degree. C., the second liquid being compatible with the first organic solvent.
- 2. The process for treating timber according to claim 1, wherein the first organic solvent comprises an alcoholic solvent.
- 3. The process for treating timber according to claim 2, wherein the alcoholic solvent is a polyol.
- 4. The process for treating timber according to claim 1, wherein the second liquid contains the second organic solvent in an amount of at least 10 wt %.
- 5. The process for treating timber according to claim 1, wherein the second liquid contains the wood preservative in an amount of 0.01-20 wt %.
- 6. The process for treating timber according to claim 1, wherein the wood preservative comprises at least one of insecticides and fungicides.
- 7. The process for treating timber according to claim 1, wherein the first immersing step is carried out under conditions of temperature and pressure which accelerate vaporization of water from the timber.
- 8. The process for treating timber according to claim 1, wherein the second immersing step is carried out under conditions of temperature and pressure which accelerate vaporization of water from the timber.
- 9. The process for treating timber according to claim 1, wherein the high moisture content timber is incised.
- 10. A process for treating timber, consisting essentially of:
- providing a freshly sawn timber having a high moisture content above a fiber saturation point of the timber,
- immersing the high moisture content timber which has not been subjected to a drying treatment in a liquid consisting essentially of a substantially water-free organic solvent which is compatible with water, and then
- subjecting the timber to conditions of temperature and pressure which accelerate vaporization of water from the timber.
- 11. A process for treating timber according to claim 10, wherein a wood preservative is present in said liquid.
- 12. The process for treating timber according to claim 10, wherein the substantially water-free organic solvent has a boiling point of not less than 150.degree. C.
