Optimization of Enzyme Mixture Degumming of Ramie Fiber

An enzyme mixture was undertaken to improve degumming of ramie fiber. Optimum parameters of enzyme production were as follows: pH 8.45, temperature 40°C, inoculums size 5%, shaking speed 205 rpm, and degumming time 24 h. Using enzyme produced under the optimal conditions, the removal of residual gum of ramie fiber was 10.94% which fulfill the textile requirement. In addition, the fiber quality was measured to evaluate effective degumming and the gum in the ramie fiber was mostly degraded compared with chemical treated.
