| 摘 要： | 粘胶纤维和再生竹纤维同为纤维素纤维,因此其混纺比的确定具有一定的难度,是有关检测部门面对的一大难题。以NaOH/尿素/硫脲溶剂体系作为溶解介质,分别对粘胶、再生竹纤维及粘胶纤维/再生竹纤维混纺材料进行溶解,通过测定所得溶液的紫外-可见吸收光谱,并依据Lasbeli定理计算出混纺材料的混纺比。结果表明,实验结果与实际配比的偏差范围为-2.13%~1.74%,误差全部在FZ/T 01053-2007的允差范围内,说明采用分光光度法对粘胶纤维/再生竹纤维混纺材料的混纺比进行定量分析具有较高的可行性。

| Abstract: | Both viscose and bamboo fiber are cellulose fiber,so it is hard to determine the blending rate when they are blended together.In this research,viscose,bamboo fiber and their blending compounds were dissolved in NaOH/urea/thiourea aqueous solution,and then UV-visible spectra were measured.The blending ratio of viscose/bamboo fiber was determined applying Lasbeli theorem.The results showed that he derivation between analysis values and actual ratio changed from-2.13% to 1.74%,all satisfying the demand of FZ/T 01053-2007.Therefore,this method was accurate and applicable for the quantitative determination of the blending ratio of viscose/bamboo fiber. |
