Abstract

Acrylic fibres are synthetic fibres produced by extruding viscous solutions of acrylonitrile co‐polymers. A spin finish is applied during the fibre‐forming process. In this work the structure of acrylic fibres has been correlated with spin finish distribution by a combined application of transmission electron microscopy (TEM), electron spectroscopic imaging (ESI) and X‐ray microanalysis (XRMA). Many irregularly shaped microcavities at the periphery of the fibres were detected by TEM. XRMA revealed that potassium and phosphorus are the elements most often found inside the spin finish material. ESI revealed that phosphorus is constantly present in all the microcavities. Therefore it seems likely that a preferential distribution of the spin finish is found inside the microcavities, just at the periphery of the fibre. This work is also an example of how both ESI and XRMA are powerful tools in morphological studies. 1991 Blackwell Science Ltd
