We treat naturally pigmented karakul wool with a surface modification system of chlorination
and catalytic bleaching, then examine its structure and properties. SEM photos reveal the
surface morphology of karakul wool, and the Allwörden reaction shows the extent of damage to
the epicuticle. The results show that the surface modification removes the bulk of the fiber
scales and bleaching increases fiber whiteness. After bleaching, the felting propensity of
karakul wool improves slightly and its dye uptake decreases. For modified and bleached
karakul wool, the felting propensity decreases, the dyeing rate increases, and equilibrium
exhaustion decreases compared with untreated karakul wool.
