Effects of Laccase on the Properties of Hemp Fabric

Abstract:

Laccase was selected totreat linen fabric. Such properties of linenfabric were analyzed as weight loss rate, whiteness, breakagestrength, capillary effect, flexural stiffness. The orthogonal test was designedabout pH value, temperature, time and concentration. The factorswere discussed on hemp fabric performance. The optimal process of laccase treatment on hemp fabricis: 50°C, pH4, 25ml/300ml, 50min. Underthe best conditions, hemp fabric weight lossrate 1.87%, breakingstrength 674.7N, whiteness 60.7,flexural stiffness 703.7, capillary effect 8.08cm,wrinkle recovery angle174 º. And the hempfiber’s microstructure changed.
