Optimization of Enzyme Mixture Degumming of Ramie Fiber

摘要

An enzyme mixture was undertaken to improve degumming of ramie fiber. Optimum parameters of enzyme production were as follows: pH 8.45, temperature 40℃, 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.%种酶的混合剂改善了苎麻纤维脱胶。产酶的最佳工艺参数为:pH8.45，温度40℃,接种量5%，摇床转速205rpm脱胶时间24h。使用最佳的条件下产生的酶，苎麻纤维的残胶的去除率为10.94%,满足紡织的要求。此外，经对纤维品质的测量，这种方法是有效的苎麻脱胶法，苎与化学处理相比，它有可降解性。
