Identification and quantification of CI Reactive Blue 19 dye degradation product in soil Coloration Technol. (IF 1.5) Pub Date : 2021-01-21 Chengcheng Feng; Xinyi Sui; Mary Ann Ankeny; Nelson R. Vinueza
Landfills are becoming the most common way to dispose textiles. The presence of different types of dyes and finishes on textiles fabrics can become an important source of pollution during the degradation process, due to the fact that these chemicals can leach to the soil. The biodegradation of dyes from dyed fabrics is not fully understood, and what can leach into the soil can be more toxic. In this

Investigation into the sequential application of cationic/anionic fixing agents to improve the oxidative washing resistance of CI Leuco Sulphur Black 1‐dyed cotton fabric Coloration Technol. (IF 1.5) Pub Date : 2020-02-11 Quratulain Mohtashim, Muriel Rigout, Chris Carr
Sulphur‐dyed cellulosic textiles are susceptible to washing powders containing activated peracid formulations resulting in obvious fading during repeated laundering. This study presents a novel one‐bath/two‐stage exhaust finishing process to improve the oxidative wash fastness of CI Leuco Sulphur Black 1‐dyed cotton fabric. The effect of the combined Tinofix ECO and Bayprotect Cl after‐treatment was

Synthesis, stability and printing properties of a novel 2‐sulphophenoxy‐4‐chloro‐s‐triazine reactive dye for ink‐jet printing of wool Coloration Technol. (IF 1.5) Pub Date : 2020-02-05 Saira Faisal, Long Lin, Matthew Clark
We report here the synthesis and characterisation of a new medium‐reactivity reactive dye containing 2‐sulphophenoxy‐4‐chloro‐s‐triazine, having enhanced the activity of the chlorine atom for further substitution by the functional groups carried by wool fibre. In addition, a dichloro‐s‐triazine dye was also synthesised for the purpose of comparison. The progress of synthesis reactions and purity of

The role of gamut, intuition and engagement in colour management in a design context Coloration Technol. (IF 1.5) Pub Date : 2020-01-22 Phil Henry, Stephen Westland
Colour management is ubiquitous in the digital world. However, despite the many advances in colour management over the last couple of decades, it remains an imperfect process. In the art and design community there is often a level of dissatisfaction and deep cynicism about colour management that can lead to lac of engagement with the process. This research explores colour management in a design context
