Enzymatic Processing of Garment Made from Lyocell Fibres

Abstract

Lyocell fibres belong to the new generation of regenerated cellulose fibres, and are used to make commercial products characterised by good drape, silky lustre and high bulk. Lyocell fibres have a specific structure, with long crystals and high degree of fibre crystallisation, high wet rigidity and tendency towards fibrillation under the impact of mechanical forces (in wet finishing). Fibrillation can be long staple and uneven (primary) or short staple and even (secondary). Two directions of finishing processes have been developed - enzymatic defibrillation with the purpose to obtain peach skin look, and additional defibrillation, aimed at obtaining almost completely smooth surface. Qualitative and hygienic properties have been monitored on finished products.
