| description | Die Erfindung betrifft ein Verfahren zur Herstellung von Endlosfasern aus einem mit Hydroxy- oder Aminoalkylmelamin modifizierten Melamin/Formaldehyd-Kondensationsprodukt. Dabei wird die hochkonzentrierte wässrige Lösung eines Melamin/Formaldehyd-Kondensationsproduktes filtriert, durch eine Spinndüse gepresst, die ausgepressten Fäden werden in einem Trockenschacht mittels heisser Luft getrocknet, und die getrockneten Fäden werden in einem Temperofen bei Temperaturen, die sukzessive auf eine Maximaltemperatur von 160 bis 250 DEG C ansteigt, behandelt, wobei das Vorkondensat aushärtet.
A process is disclosed for producing filaments from a hydroxy- or aminoalkylmelamine-modified melamine/formaldehyde condensation product. The highly concentrated aqueous solution of a melamine/formaldehyde condensation product is filtered, extruded through a spinning nozzle, the extruded threads are dried in a dry shaft by means of hot air, and the dried threads are processed in a tempering furnace at temperatures that rise progressively up to a maximum temperature from 160 to 250 DEG C, thus hardening the pre-condensed product.
L'invention concerne un procédé de fabrication de filaments à partir d'un produit de condensation de mélamine/formaldéhyde modifié par une hydroxyalkylmélamine ou aminoalkylmélamine. On filtre une solution aqueuse très concentrée d'un produit de condensation de mélamine/formaldéhyde, on l'extrude à travers une filière et on sèche à l'air surchauffé les fils extrudés dans un puits de séchage. On traite ensuite les fils séchés dans un four à recuire à des températures qui augmentent successivement jusqu'à une température maximale comprise entre 160 et 250 DEG C, de manière à durcir le produit pré-condensé. |
