Method for brightening synthetic fibers and plastics with granulated optical brighteners |
摘要 |
A method has been found for brightening synthetic fibers and plastics. In this method, a granulate optical brightener is incorporated into the synthetic fibers or plastics, the granulated optical brightener being obtained via compacting of an optical brightener in powder form in a pressure compactor under a pressure of from 3 to 50 kNewton/cm of tube length and then comminuting the resultant compactate.
