 Full text | Abstract: In this study wool fabrics were treated first with proteases (Savinase 16L) at different temperatures over various periods of time. The samples were then tested for some mechanical and physical properties. To overcome the strength loss of the fabric as a result of the protease treatment, the after-treatment with trans-glutaminases was examined. The results show that the felting behaviour of the proteases treated wool was improved and the degree of whiteness enhanced. Furthermore, the pilling performance of the samples was also improved; however, such treatment can cause irreversible and excessive damage to the fibre cuticle, with consequent high levels of weight and strength loss. The dyeing of untreated and enzyme treated wool with madder leads to an improved dyestuff uptake and a distinctive difference in the colour shade of the latter. In addition, treatment with T-Gases leads to a significant increase in tensile strength and may compensate for the damage caused by protease. |
