Abstract: The present invention relates to a method for producing a heat-resistant crimped yarn comprising: twisting yarn of a heat-resistant high functional fiber; twist-setting this twisted yarn by heat treatment; and untwisting this twist-set yarn, wherein a snarl value of the twist-set yarn is not more than 6.5.

Abstract: The invention provides heat-resistant crimped yarn, of which the constituent heat-resistant high-functional fibers are prevented as much as possible from being deteriorated under heat in the process of producing the yarn. Not losing excellent properties of heat resistance and flame retardancy intrinsic to the heat-resistant high-functional fibers, the crimped yarn has a good elongation percentage in stretch, a good stretch modulus of elasticity and a good appearance, and it fluffs little and releases little dust. The heat-resistant crimped yarn comprises heat-resistant high-functional fibers, and is characterized in that it does not deteriorate under heat, and that its elongation percentage in stretch is at least 6%, its stretch modulus of elasticity is at least 40%, and its tenacity falls between 0.15 and 3.5 N/tex.

Abstract: A wood treating method and apparatus whereby a wood which is thin or bent, such as a soft wood or wood removed during growth or a wood from thinning, is strengthened, straightened and molded in any desired shape, wherein after the wood is heated and softened in a high temperature high pressure atmosphere, mechanical compressive forces are applied to the wood to minimize the voids in the wood; thus, the wood is hardened, strengthened and the bent wood is corrected, making it possible to form the wood in any desired shape without lumbering the same.

Abstract: This invention discloses a process for producing 2,6-bis (4-hydroxy-3,5-dimethoxyphenyl)-3,7-dioxabicyclo [3.3.0] octane, i.e. syringaresinol and stereo-isomers thereof, from plants which contain lignin with syringyl unit. The process comprises heating plant under pressure in hydrous condition, and then quickly discharging them therefrom into an environment at atmospheric pressure so as to explode into pieces and subjecting the fine pieces to extraction with organic solvent such as methanol and acetone or an alkaline solution such as sodium hydroxide and purification. Syringaresinols are useful like ginseng as a tonic.
