Optimisation of purple dyeing with Mexican cochineal in cotton with multivariate analysis and the response surface method

open access: yesColoration Technology, EarlyView.
Abstract This study aims to optimise the dyeing process of cotton fabrics using Mexican cochineal (Dactylopius coccus Costa). The objective is to obtain purple hues through the design of experiments and by using multivariate analysis. Plackett–Burman experimental designs and the response surface method were used to systematically optimise the dyeing ...

Rapid and high exhausted coloration technology: Dyeing of bovine hides under vacuum

open access: yesColoration Technology, EarlyView.
Abstract In the current study, the aim was to improve the dyeing properties of wet‐blue and crust leathers under vacuum conditions, increasing the dyestuff exhaustion, and thus obtaining environmental and economic gains. In this context, dyeing was performed using conventional dyestuff and water ratios in a vacuum environment with 20 kPa pressure, and ...

Synthesis and characterisation of iron oxides: Effect of calcination temperature and their application as inorganic pigment

open access: yesColoration Technology, EarlyView.
Abstract This research aimed to investigate the effect of calcination temperature on the phase, morphological and optical properties of iron oxides: hematite (α‐Fe₂O₃), magnetite (Fe₃O₄) and goethite (α‐FeOOH), synthesised by co‐precipitation, aiming at their applications as pigments.

The BioColour Library

open access: yesColoration Technology, EarlyView.
Abstract The attraction of adopting natural and bio‐based colourants in applications has grown, but their use suffers from a lack of certification bodies, standards and reference data. In the BioColour project, we are developing an open database and tools for the characterisation, authentication and quality analysis of biocolourant sources ...
