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.
