采用酸性果胶酶处理剑麻纤维,探讨了处理工艺条件(pH、温度及时间)对纤维减量率、含水率、回潮率的影响,并利用SEM、FTIR、TG表征了处理前后纤维的表面形态、分子基团及热稳定性.结果表明,酸性果胶酶能有效去除剑麻纤维表面的果胶、蜡质、半纤维素等,使其质量损失率增加,同时对其表面有明显刻蚀,有助于剑麻纤维脱胶,增加了热稳定性.

Sisal fiber was treated with acidic pectinase. The effects of treatment process (pH, tempera-ture and time) on the weight loss rate, moisture content and moisture regain were investigated. The surface of the fiber morphology, molecular groups and thermal stability before and after pectinase treatment were char-acterized by SEM, FTIR and TG. The results showed that the acidic pectinase could effectively remove pectin, wax and hemicel ulose, and increase the weight loss. In addition, the surface of the sisal fiber was significant-ly etched, which was helpful to the degumming and improve the thermal stability of sisal fibers.
