Effect of chlorination treatment on the thermogravimetric behaviour of wool fibres

The thermal behaviour of wool, untreated and chlorinated to various extents , was investigated. The kinetic parameters of the water loss and pyrolysis processes were computed and, based on their values, the way chlorination tr eatment affects wool fibre is discussed. As it appears, the chlorination pr ocess affects the fibre only superficially and not its internal chemical co mposition, as the values of the kinetic parameters of the thermal decomposi tion of wool fibre do not seem to be influenced at all by the treatment.
