Studying of Morphology and Crystallinity of Jute Fibers Treated with Laccasses

Laccase is an oxidative enzyme that interfere in oxidation of phenolic compounds, aminophnols, polyphenols, polyamines, specific mineral ions, and aryl diamines compounds with oxygen reduction in water. Other usage of Laccasses is in wood pulp bleaching and lignin polymerization. In this research Laccase used and its influence on Jute properties is studied. Jute fabric treated in 50ºC and pH=4.5 with 0% and 100% weight percentage of Laccase in 3 hours. Surface morphology of fabric and crystallinity were investigated by Scanning Electron Microscopy (SEM) and X-ray diffraction methods. In SEM images it observed that with applying Laccases the fiber surface is more smoothness and impurities is decreased. In crystallinity investigation it observed that applying Laccase is the reason of increasing in crystallinity
