ASPECTS REGARDING FINISHING OF LYOCELL WOVEN FABRICS

Abstract Lyocell fibres have made a special impact on the worldwide textile market since their appearance. The trends in the field of textile fibres and the necessity of increasing the competitiveness of textile articles motivated an analysis of lyocell fibres’ potential for the garment sector, and especially for fashion. To this end, some different finishing experiments on lyocell woven fabrics have been conducted. The technological experiments had the primary fibrillation effect-enzymatic defibrillation-secondary fibrillation in view. For obtaining these effects, rope finishing with/without woven fabrics causticising was carried out, followed by defibrillation (biopolish treatment) before or after dyeing, using different cellulasic enzymes such as Bactosol CA (Clariant), Perizym 2000 and Perizym LYO (Textil Chemie GmbH Dr. Petry). The experiments considered the evidence of the influence of these technological stages on the surface modification that appears in finishing lyocell textile materials.
