Entwicklung einer Methode zur Bemusterung und Rezeptierung von Masterbatches bei der Herstellung von spinngefaerbten Synthesefasern Abschlussbericht

Spin-dyeing of fibers is carried out via coextrusion of the polymer and the color-masterbatch. This method surpasses the common dyeing methods, as no solvents are used and no purification of rinsing water is necessary. Furthermore, the whole dyes rsp. pigments are incorporated into the fibers, and the fibers exhibit high lightfastness. Here, the development of appropriate pigment masterbatches for PET, PP, and PA6/66 fibers of any required color is described.SIGLEAvailable from TIB Hannover: F04B494 / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekDeutsche Bundesstiftung Umwelt, Osnabrueck (Germany)DEGerman
