Abstract
The invention relates a method and arrangement for processing and measuring textile waste. Textile waste comprising at least a first component of organic fibres and a second component of non-organic fibres is processed (200) in a processing stage. A suspension sample is obtained (202) from the output of the processing stage. One or more colour components are fed (204) to the sample which is mixed (206) for a predetermined period. The suspension sample is directed (208) to a measurement chamber where optical radiation is directed (210) at the suspension. Interaction of the optical radiation with the suspension is detected (212) optically and the amount of different components in the sample is determined (214) based on the detection.
