Title (EN) PROCESS FOR THE PREPARATION OF FIBERS
(FR) PROCEDE DE PREPARATION DE FIBRES
Abstract: front page image
(EN)Fibers coated with polymer are prepared by adding the polymer to a fiber material, typically cellulose pulp, and subjecting the fiber material with the added polymer to impact of grinding forces in a defibrator, typically a hammer mill. The resulting fibers are very efficiently coated with the polymer and are suitable as binder fibers in fibrous materials consisting completely or partially of the coated fibers bonded through the polymer, and as reinforcing fibers in fiber-reinforced cement products. The polymer is preferably applied as a hot melt, and the defibration is performed immediately after the application.
(FR)Des fibres revetues d"un polymere sont preparees par addition du polymere a un materiau fibreux, d"une maniere caracteristique de la pulpe de cellulose, et en soumettant le materiau de fibres avec le polymere ajoute a l"impact de forces de broyage dans un defibreur, generalement un marteleur. Les fibres resultantes sont revetues de polymere avec une grande efficacite et se pretent a une utilisation comme fibres de liaison dans des materiaux fibreux consistant completement ou partiellement des fibres revetues liees au travers du polymere, et comme fibres de renforcement dans des produits de ciment renforces avec des fibres. Le polymere est applique de preference a l"etat de fusion a chaud, et le defibrage s"effectue immediatement apres l"application.
