摘要: 为了缩短大麻脱胶时间和提高纤维质量,通过对大麻微生物-蒸汽爆破联合脱胶技术的不同参数试验,确定了脱胶微生物Dm111对大麻的处理温度为35℃,180 rmp振荡培养6h;蒸汽爆破的较好条件为压力2.5MPa,保压时间120s。大麻微生物-蒸汽爆破联合脱胶的大麻纤维素含量为77.01%,而且果胶、半纤维素和木质素的含量比原麻分别降低了89.15%,33.75%和30.64%,胶质去除效果较好,纤维分裂度和强度分别达到689 mm/mg 和80N。

Abstract: To shorten the duration of hemp degumming and increase the fiber quality, microbial and steam explosion united degumming technique was studied. In this study, hemp was treated by fast retting using Dm111 strain and followed by steam explosion treatment. Different parameters of this technique were tested. The results indicated the best united-degumming conditions were: during the microbial retting, hemp was incubated with Dm111 strain at 35℃ shaking-flask 180 rpm(revolutions per minute)for 6 hours; And the steam explosion was performed in a holding-time of 120 seconds and a pressure of 2.5MPa. After treated by this technique, the analysis data showed that the cellulose of hemp was 77.01%, and the pectin, hemicelluloses and lignin were removed by 89.15%, 33.75% and 30.64%, respectively. The degree of fiber separation was 689 mm/mg and the strength of fiber was 80N.
