déjettement

CONT: Le déjettement est de loin le défaut de séchage le plus commun qui entraîne le déclassement des sciages de résineux de dimension.

CONT: The high temperature and humidity will help soften the lignin between the wood fibers and thus reduce the stresses caused by shrinkage that in turn produce crook and twist and other forms of warp.
CONT: Lumber cut off-center from the pith (core) of the log will naturally have stress which results in crook or side-bend in many species, especially hardwoods.
