Combined fluorescence dichroism and polarization microscopy of cotton fibres under stress
article
With the aid of fluorescent staining it is possible, in a microscope specially adapted to this purpose, to investigate the fluorescence dichroism of the cotton fibre.
As a rule, the S and Z spiral parts can thus clearly be seen. The staining is clearly visible in the outer growth layers. Combination of fluorescence microscopy and polarization microscopy with micro-stress experiments shows slip phenomena between the growth layers during stress. These slip phenomena are clearly visible in fibre parts in which a part of one spiral direction is well developed in the outer layers, while in the inner layers this spiral part do es not coincide for the different layers.
The phenomena described are probably important for mercerization under tension.
