Paper Title:
Application Performances of Gemini Surfactant as Silk Degumming Auxiliaries
  Abstract

To investigate the Application Performances of the anionic gemini surfactant Ethanediyl-α,ω-bis(sodium N-lauroyl-β-alaninate)(EBLA) as silk degumming auxiliaries, the surface activity of the gemini surfactant was measured by the surface tension method. The dependence of degumming rate on surfactant concentration and degumming time were discussed, and the whiteness, tensile strength and capillary effect of the degummed silk fabric were measured. The results revealed that the gemini surfactant possessed excellent surface activities and its degumming effect was pretty good, the critical micelle concentration(CMC) of EBLA was 4.74×10-5 mol·dm-3, and the surface tension at the CMC(γCMC) of it was 26.6 mN·m-1. With lower dosage of the surface active agent and shorter degumming time, the perform indexes of the fabric degummed by the gemini surfactant EBLA were better than those of the fabric degummed by marseille soap.
