Abstract
The invention pertains to a technique for determining the dye uptake or measuring one or more structural parameters or mechanical properties of polymeric fibres. This technique entails measuring the Raman spectrum of the fibres during or after a spinning process. After the Raman spectrum has been treated, a model is applied to it which is derived from the Raman spectra of fibres having the same chemical composition as the fibres to be examined.
