In order to find out the method of qualitative identification of glucose biomimetic fiber,six qualitative identification methods of glucose biomimetic fiber were selected including color and luster,burning behavior,microscopy,solubility,fiber melting point and infrared absorption spectrum.According to the characteristics of each method,four kinds of fibers were selected for comparative analysis,trying to find out a simple method to identify glucose bionic fiber.It is concluded that the identification of glucose biomimetic fiber needs to be combined with visual sense to distinguish color and luster,and the polylactic acid fiber can be excluded according to the difference of melting point of special burning phenomenon and microscopic observation,the identification of glucose biomimetic fibers is assisted by the use of dichloromethane reagents or infrared spectroscopy,and several methods are verified to be able to identify glucose biomimetic fibers accurately.
