Study on the Oxidized Cotton Fiber Treated with Sericin

摘要

In order to achieve the protein property of cotton fiber, combinative ability between dialdehyde cellulose cotton fiber and sericin was studied in this paper. The proteinic oxidized cotton fiber was expected to be obtained by treating the oxidized cotton fiber with sericin solution. Effect of different factors, such as oxidized degree, concentration of sericin solution, pH value, treating time and treating temperature, on the weight and the tensile properties of cotton yarns were discussed. The morphology and structure of sericin proteinic cotton fiber were also analyzed by means of SEM, FT- IR, XRD, TG and DSC. The results showed that sericin could be directly coated onto the oxidized cotton fiber without any other reagent. The weight gain of oxidized cotton fiber was definitely affected by different processing parameters. After treating with sericin solution, the thermal stability of the oxidized cotton fiber improved and the surface became smooth, but the crystallinity and tensile properties changed little.
