【摘要】 介绍了新型蛋白质复合再生纤维素纤维的制备技术、性能特点及开发应用。重点对该纤维的形态结构及性能进行了分析,得出其纤维截面形态结构与普通黏胶纤维不同,呈现不规则扁平中空结构,外缘圆滑。红外光谱图表明蛋白质复合再生纤维素纤维是由纤维素纤维和蛋白质纤维复合而成;X射线衍射分析表明,复合纤维随蛋白质超细粉体添加量的增加,取向度和结晶度下降。采用凯氏定氮法、次氯酸钠法对蛋白质复合再生纤维素纤维进行蛋白质含量的测定和对比分析,结果表明:虽然在制备过程中蛋白超细粉体随着添加量的增加,流失量增加,但是流失后纤维中蛋白质含量仍然相对较高,保证了纤维的性能特征。更多还原

【Abstract】 The paper introduces the preparation technology, characteristics and application of new type of regenerated protein and cellulose composite fiber, and also analyzes the morphological structure of this fiber, the cross section of which appears irregular flat and hollow structure with smooth edges compared to the common viscose fiber. And infrared spectrum shows that the new type of regenerated protein and cellulose composite fiber is composed of cellulose fiber and protein fiber; X-ray scattering analysis shows that the orientation and crystallization of this composite fiber decrease with the increasing of protein ultrafine powders. Meanwhile, the protein content are tested and compared by using Kjeldahl and sodium hypochlorite methods, the results show that the losses of protein ultrafine powders increase with the increasing of the amount of that, but the protein content of fiber has remained comparatively high, which can guarantee good properties.更多还原
