The inkjet printing process for Lyocell and cotton fibres. Part 1: The significance of pre-treatment chemicals and their relationship with colour strength, absorbed dye fixation and ink penetration

Ink‐jet printing process for lyocell and cotton fibres. Part 2: The relationship of colour strength and dye fixation to ink penetration

“…The lyocell fabrics used were desized and scoured standard Tencel Pretreatment and printing procedure Pretreatment was carried out using the formulations resulting from varying the five factors at the low and high levels as detailed in part 1 [11]. Additionally, a reduction inhibitor Lyoprint RG was incorporated into the formulations, at a concentration of 15 g l )1 in each case.…”

“…Absorbed dye fixation was measured based on absorbance measurements on the combined wash-off liquors collected after printing and fixation, using an appropriate calibration procedure, as described previously [11].…”

Modification of cotton fabric with a dendrimer to improve ink-jet printing process

“…Evaluation of percentage of absorbed dye fixation from the inkjet printing technique used a methodology adapted from previously established procedures for textile dyeing with reactive dyes (Bone, Le, Philips, & Taylor, 2008;Kaimouz et al, 2010;Morris, Leuis, & Broadbent, 2008). Two equal square pattern printed fabrics of 3.5 cm × 3.5 cm at 1200 dpi were used to determine the percentage of fixation; one was printed with the reactive ink on a 100% polyester fabric and the other was printed with reactive ink on a cotton fabric.…”

“…All the printed fabrics were treated with superheated steam at 110 • C for 10 min for colour fixation (Kaimouz et al, 2010;Yuen et al, 2004a). The steamed fabric samples were washed with cold water and subsequently washed again in 10 g/dm 3 of non-ionic detergent (Synperonic BD) at 60 • C for 10 min until all the unreacted dyes and other chemicals were removed from the fabric surface (Yuen et al, 2004a).…”

“…Previous studies have detailed the increase of reactive ink fixation through the modification of reactive dyes (Li & Tincher, 1999), fabrics (Eltz, Schrell, & Russ, 1994;Hutter & Matzinger, 2000;Kaimouz, Wardman, & Christie, 2010;Kanik & Hauser, 2003;Zhang, Westland, Cheung, Burkinshaw, & Blackburn, 2009) and ink formulation (Soleimani-Gorgani & Shakib, 2013), as well as the use of fixation-enhancing chemicals in the pre-treatment process. (Yuen, Ku, Choi, & Kan, 2008).…”
