Title
(EN) HIGH BULK, HIGH STRENGTH FIBER MATERIAL WITH PERMANENT FIBER MORPHOLOGY
(FR) MATERIAU FIBREUX EXTREMEMENT RESISTANT MORPHOLOGIE STABLE
Abstract
(EN)
Wood fiber morphology can be permanently altered by introducing a substantial kink, twist, curl, crimp or other curvilinear deformation into a wood fiber. Wood fibers are first Fiberized using mechanical treatment processes and then are subjected to super atmospheric temperature/pressure steam explosion processing. The fiber morphology becomes a permanent characteristic of the fiber which is not relaxed in time, by contact with other treatments or through use.
(FR)
Selon cette invention, il est possible de modifier en permanence la morphologie des fibres ligneuses en introduisant dans celles-ci un vrillage, une torsion, une bouclette, une ondulation ou autre déformation curviligne. On procède d'abord au défibrage des fibres ligneuses par un traitement mécanique, puis on les soumet au vapocraquage à une température/pression supérieures à la pression atmosphérique de façon à conférer à la fibre une morphologie stable qui ne se relaxe pas au bout d'un certain temps, au contact d'autres traitements ou en utilisation.
