Abstract:

Presently biotechnology plays an important role especially in the field of environmental protection. In the textile industry enzymes are often used in many technological processes as they are ecological. Flax fibres are special among textile raw materials due to their properties. Flax fibres, besides cellulose, contain non-cellulosic substances such as hemicellulose, lignin, pectins, waxes and fats. Lignin is the substance not desired in fibres. Enzyme such as laccase is active during the decomposing of lignin-cellulose complex. Hence, the research task attempts to apply laccase complex in the treatment of woven fabrics made of flax fibres. The aim of the research was to test the possibility and effectiveness of applying laccase complex produced by Cerrena unicolor strain in the scouring processes of linen fabrics. The tests performed proved that the pre-treatment with laccase complex from Cerrena unicolor provides a high level of water sorption capabilities in of linen fabrics. The results obtained confirm that linen fabric pre-treatment with laccase can be an alternative to traditional chemical scouring.
