Abstract (en)
[origin: WO2004022837A1] The invention relates to a method for brightening synthetic fibres and plastics. According to said inventive method, a granulated optical brightener is incorporated into the synthetic fibres or plastics, wherein the granulated optical brightener is obtained by means of compacting an optical brightener into a powder form in a pressure compacting machine at a pressure of between 3 - 50 kNewton/cm of tubular length and subsequently comminuting the obtained compact.
