Effect of Padding Parameters on Shade Depth and Dye Penetration of Digitally Printed Cotton Fabrics
Abstract:This study determined padding process parameters that influence the shade depth (K/S, color strength) of the inkjet printed fabrics. Three roller speeds (20, 40, and 60 rpm) and six roller pressures (5, 15, 20, 40, 60, and 70 psi) were studied. The fabric samples were padded through liquor (formula: 0.8% alginate, 4% sodium hydroxide, 10% urea, and 85.2% water, all concentrations in w/w) in a one-dip-one-nip procedure with wet pickup ranging from 84.9% to 99.0%. Padded samples were printed with a piezotechnique based Mimaki TX-2 printer, post-treated, and evaluated for their color. Optimum shade depth was obtained at a combination of 20-psi roller pressure and 40-rpm speed.

For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.
Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
