Peeling. (14) Rounding. (C) Others (15) Mangled. (16) Cut. (17) Melted. (18) Natural end of cotton fibre.
From Hearle et al. (1998).
NOTE: With the exception of Fig. 3a,b, which is a 1-mm diameter monofil, and Fig. 3d, which is a film,
the scales of the SEM pictures can be inferred from the fact that all the fibres are typical textile fibres with
diameters in the range of 10 to 20 km.
