GS 氧化交联变性淀粉浆料的性能分析

通过对GS氧化交联变性淀粉浆料的浆液和浆膜的各项性能指标进行系统的测试与分析，得到GS氧化交联变性淀粉的水溶性良好，浆液黏度值稳定，成膜完整，浆膜的吸湿性较小，耐屈曲性良好，断裂强力较大。分别将GS氧化交联变性淀粉浆料和PV A与变性淀粉、固体聚丙烯酸进行配伍，对比两组配方下的浆纱强力、毛羽和耐磨性能等。实验结果表明，GS氧化交联变性淀粉的浆纱性能良好，可满足纯棉纱上浆要求。

Property analysis of GS oxidative crosslinking modified starch

The size and size film properties of GS oxidative crosslinking modified starch were tested and analyzed .The result shows that the water solubility of GS oxidative crosslinking modified starch is good , size liquor viscosity is stable ,size film forming is complete ,moisture absorption of size film is small ,the resistance to buckling and breaking strength is high .GS oxidative crosslinking modified starch and PVA are respectively mixed with modified starch ,solid polyacrylate ,the strength ,hairiness and abrasion re-sistance of two kinds of size formula for cotton are compared .It is concluded that the sizing performance of GS oxidative crosslinking modified starch is good enough to meet the requirements of cotton sizing .
