Synthesis and Characterization of Quaternary Ammonium Polyether Blocked Polysiloxane

Abstract:

In this research, a new quaternary ammonium polyether blocked polysiloxane (QBPEAS) was synthesized by reaction of epoxy polyether terminated polydimethylsiloxane with tetramethylethylenediamine. The chemical structure of QBPEAS was characterized by IR and ¹H-NMR. And then the film morphology on fiber substrates was investigated by scanning electron microscope (SEM). The results showed that QBPEAS has a good film-forming ability and can form a macro-smooth Sloane film on the treated fiber surface. In addition, QBPEAS could obviously decrease the bending rigidity and improve the hydrophilicity of the treated fabrics, but has little influence on the fabric whiteness.
