Study on Structure of Oxidized Raw Bamboo Fiber Treated with Sericin Protein

In order to improve the finishing effect of raw bamboo fiber treated with sericin protein, raw bamboo fiber was selectively oxidized by NaIO(4) and then treated with sericin solution. The morphology and structure of sericin proteinic raw bamboo fiber were analyzed by means of SEM, XRD, TG and DSC. The treating results show that sericin protein could be directly coated onto the oxidized raw bamboo fiber without any other reagent and a covalence formed between amido and aldehyde group. After being treated with sericin protein solution, the thermal stability and crystallinity of the oxidized raw bamboo fiber improved and the surface became smoother.
