Effect Of Extractives On Shrinkage And Other Hygroscopic Properties Of Ten Southern Pine Woods
Abstract
The significance of extraction treatment on the ten woods of the southern pines was studied. Additional data were obtained on fiber saturation point and equilibrium moisture content. The hygroscopic properties of these woods vary widely with extractive content. Extraction of wood with hot-water and organic solvents greatly improved the volumetric shrinkage—specific gravity relationship. The variation of shrinkage anisotropy with specific gravity was discussed.References
