Abstract

The tendency of wool to felt and shrink is mainly due to its scaly structure. The enzymatic treatment of textiles significantly improves some of their properties as well as increases their aesthetic values and comfort of use. The application of enzymes in the wool modification process was studied, and it was proven that the application of enzymes has an important influence on changes in the surface structure. However, although proteases are large molecules, their attack is not only limited to the scales, they penetrate inside the fibre causing unacceptable weight and strength loss. It is believed that if the proteases are chemically modified in order to increase their molecular weight, then they will act just on the surface of the fibres, thus providing wool with anti-shrinking behaviour. The free enzyme penetrated into wool fibre cortex while the modified enzyme, with a bigger size, was retained at the surface, in the cuticle layer. Modified proteases can be a promising alternative for wool bio-finishing processes at an industrial level, since it is an effective way of removing wool scales.
