Abstract (en)
[origin: CA2121136A1] Described are methods of manufacturing a cellulose-acetate bundle. the filaments making up the bundle being produced by extruding a solution containing, in addition to cellulose-(2,5)-acetate and solvent, non-toxic compounds which are only slightly soluble in the solution and whose molecular diameter is at least 30% less than the diameter of the filaments. Water-soluble or bacteriologically degradable organic compounds, in particular starch, starch derivatives or dextrins, are used as the additives.
Abstract (fr)
Procédé de fabrication d'un faisceau d'acétate de cellulose. Les fibres qui composent ce faisceau sont obtenues par extrusion d'une solution à filer. Outre de l'acétocellulose 2,5 et un solvant, cette solution contient des composés non toxiques qui y sont difficilement solubles. Ces composés ont un diamètre qui fait au moins 30 % de moins que celui des fibres. On utilise comme additifs des composés organiques bactériologiquement dégradables ou solubles dans l'eau, en particulier de l'amidon, des dérivés de l'amidon ou des dextrines.
