板蓝根粘胶共混膜的物理性能研究

Study on the Physical Properties of Isatis Viscose Membrane

文章将板蓝根提取物溶液和粘胶纺丝液进行共混制得共混膜,对共混膜的物理性能进行了测试。结果表明:与纯粘胶膜相比,共混膜的断裂强力、断裂伸长率和初始模量都有所减小;共混膜的断裂强力和断裂伸长率都随共混纺丝液中板蓝根提取物含量的增加而减小;初始模量值随着板蓝根含量的增加先降低后升高。

Isatis extract was added to viscose spinning solution to get polyblend membrane. The physical properties are tested. The result shows that compared to the viscose membrane, both the breaking strength and the breaking elongation are of the blend membrane are decreased. In addition, the membrane breaking strength and the breaking elongation are all decreased with the increase of the content of the isatis extract. The initial modulus is first decreased and then increased.
