Abstract:

Based on the architecture units of N-β-aminoethyl-γ-aminopropyl polydimethylsiloxane (ASO-1) and carboxyl modified polyether-b-polydimethylsiloxane (CPES), ASO-1/CPES supramolecular film was formed on the surface of cotton fabric. The film forming performance and application were studied. Field emission scanning electron microscope (FESEM) investigation showed that the fabric surface anchored with ASO-1/CPES supramolecular film was much smoother than that of the control sample. Compared with the fabric treated with ASO-1 alone, the fabric with supramolecular film has better softeness, whiteness and hydrophilicity. In addition, when the mass ratio of ASO-1 to CPES was 1:2, the treated fabric showed the optimum softness and certain hydrophilicity without affecting its whiteness, demonstrating the best comprehensive applicational performance. Besides, the suitable viscosity and amino value of ASO-1 for the suparmolecular assembly was 3650 mPa•S and 0.9mmol/g, respectively.
