Abstract
The unmodified and prechemically treated wool fibers were ground, crushed and pulverized in dry and wet state by the different mechanically methods. The fractured products with the different shapes and sizes could be produced. Two kinds of powder; the fine powder of less than 10 μm (top size) and spindle shape particles consist of cortical cells, were finally obtained by several combinations of grinding, crush and pulverization method. The differences in the shape and size of these particles are essentially dependent on both the mechanical mechanism of the used laboratory apparatus and the chemical/physical structure of wool fiber induced by the different pre-treatments.
