蒸汽爆破和微生物酶解处理对剑麻纤维结构的影响
Effects of steam explosion and micro protease treatments on structure of sisal fiber
摘要
Abstract
In this study, sisal fiber was treated with steam explosion and enzymolysis, and the effect of these two methods on chemical composition, diameter, moisture regain, moisture content, alkali resistance, thermal stability and tensile strength of sisal fiber was tested. Micro-surface structure,the change of functional group of the two kinds of sisal fiber treated were analyzed by scanning electron mieroseopy(SEM), Infrared spectroscopy(IR), Differential Scanning Calorimetry(DSC) and Thermal Gravimetric analysis(TG). The results showed that the steam explosion impacted greatly on the sisal fibers about the semi-cellulose component, but there were not new absorption peak in Infrared Spectra. Enzymolysis reduce the content of lignin contrapuntally and increase the content of cellulose in sisal.There was significant etch on the surface of sisal fiber. It was better for the cohesiveness with materials. The thermal stability of sisal fiber was improved,treated by the two methods.关键词
