竹炭粘胶纤维的分析与鉴别

由于竹炭微粉的加入，竹炭粘胶纤维与普通粘胶纤维性能存在明显差异。为解决二者鉴别困难的问题，通过密度法、燃烧法、溶解法、扫描电镜法、热分析法、吸附法、抗菌检测法和负离子测定法对竹炭粘胶纤维进行分析和鉴别。结果表明：8种方法均能有效的将竹炭粘胶纤维和普通粘胶纤维鉴别开来。其中，密度法、燃烧法和溶解法适用于简单鉴别；扫描电镜法、热分析法、吸附法、抗菌检测法和负离子测定法适用于复杂的定性鉴别。同时，进一步分析竹炭扫描电镜照片，竹炭粘胶纤维确实具有较高的吸附性。

Analysis and identification of bamboo-charcoal viscose fiber

Due to the addition of bamboo charcoal micro-powder, obvious differences exist between bamboo-charcoal viscose fiber and ordinary viscose fiber. In order to solve identification problem between them, this study used density-based method, combustion method, dissolution method, scanning electron microscopy, thermal analysis, adsorption method, antibacterial testing method and anion measurement to identify bamboo-charcoal viscose fiber. The results showed that any of the above 8 test methods can distinguish bamboo-charcoal viscose fiber from ordinary viscose fiber, in which, the density-based method, combustion method and dissolution method are suitable for simple identification, whereas scanning electron microscopy, thermal analysis, adsorption method, antibacterial testing method and anion measurement fit for complex qualitative identification. Analysis of scanning electron microscope photographs of bamboo charcoal verifies that the bamboo viscose fiber has higher adsorptivity.
