摘要
应用纤维素酶单独处理、纤维素酶和半纤维素酶复配后进行苎麻生物酶脱胶及脱胶纤维强力影响因子组合优化实验,以苎麻残胶率和纤维断裂强力和断裂强度为判断依据。结果表明纤维素酶和半纤维素酶按照纤维素酶∶甘露葡聚糖酶∶木聚糖酶=2∶1∶1的比例复配,复配酶总浓度为8g/L,55℃,0.2%EDTA,135min,浴比1∶15,pH7,摇床转速200r/min时,处理工艺较为理想,该处理后精干麻的残胶率最低为6.65%,断裂强力为44.4625cN;纤维断裂强度为5.2309cN/dTex。
The optimized study on ramie degumming and fiber strength with cellulase、cellulase and hemieellulase were introduced in this paper. The residual gum rate, breaking strength and breaking tenacity were used as the judgment basis. The results showed that the finest combination of influencing factors during ramie degumming with the mixed enzymes(enzyme proportion of cellulase: mannan glucanase: xylanase is 2:1:1) concentration 8g/L, the treating temperature 55℃,0.2% sodium EDTA, treating time 135min, bath ratio is 1:15, pH7, 200rpm, with which the lowest residual gum rate was 6.65%, the breaking tenacity was 44.4625cN, the fiber breaking strength was 5.2309cN/dTex.
