The surface appearance and feel of fabrics produced from the new cellulosic fibre Tencel can be enhanced by cellulase treatment. Laboratory‐scale studies have been carried out using purified Trichoderma reesei cellulase components to determine which enzymes provide a benefit and which cause detrimental effects on Tencel fibre. Two enzymes were identified as beneficial and this information was used to produce new commercial cellulase products, using genetic engineering to remove detrimental components and increase amounts of the beneficial enzyme components. The effects of the new cellulases on Tencel fibre (both 100% pure and blends) were then evaluated. The observed advantages included improved hand‐feel and reduced garment damage, especially in blends with other cellulosics.
