- In the paper, a one-step inkjet printing technology with reactive dye ink and cationic compound ink for cotton fabric was reported. Cationic ink of 3-chloro-2-hydroxypropyltrimethyl ammonium chloride (CHPTAC) and reactive dye ink were printed simultaneously on the sized cotton fabric, and then the sample was steamed. Response surface methodology (RSM) was used to investigate the influences of steam conditions on the K/S value and dye fixation rate. The K/S value, dye fixation rate, staining of the white ground and colorfastness of cotton fabrics treated with different inkjet printing methods were compared. X-ray photoelectron spectrometer (XPS) analysis and attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectrum confirmed the reaction of CHPTAC to cotton treated by one-step inkjet printing technology. And a suggested reaction process of the one-step inkjet printing method was proposed through Gaussian calculation.
