Chemical profiling and characterisation of anthraquinone‐based polyphenols as biocolourants from Cortinarius semisanguineus

Coloration Technology, EarlyView.
Abstract Anthraquinone dyes are known for their significant colour (brightness of shade in the red, blue and green areas) and light fastness properties compared with other synthetic dyes (such as azo‐based dyes). However, challenging multi‐step synthesis of anthraquinones and limited access to fewer substituents result in insufficient reactivity ...

Investigation into the aqueous and supercritical carbon dioxide dyeing of polyester and cellulose acetate: The influence of temperature and carriers on fabric coloration and dye levelling

Coloration Technology, EarlyView.
Abstract This paper investigated the effect of temperature and time on the dyeing of polyester and cellulose diacetate and demonstrated the benefits of supercritical carbon dioxide (SC‐CO2) dyeing. It was evident that the SC‐CO2 medium enabled effective coloration of polyester at lower temperatures, ca.

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

Coloration 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 ...

Exploration of the natural dye alizarin for supercritical carbon dioxide dyeing of polyester, polyamide and cellulose acetate fibres

Coloration Technology, EarlyView.
Abstract Conventional textile dyeing utilises large amounts of water and generates significant amounts of wastewater, highlighting the need to utilise more sustainable dyeing methods. Supercritical carbon dioxide (scCO2) dyeing offers a zero‐water, zero‐wastewater alternative with reduced energy requirements and carbon dioxide recyclability. While both

The Core‐Periphery Model Under Additively Separable Preferences

Journal of Regional Science, Volume 65, Issue 2, Page 378-402, March 2025.
ABSTRACT This paper reexamines Krugman's core‐periphery model by substituting his constant elasticity of substitution (CES) utility with a general additively separable utility that comprehensively captures the pro‐competitive effect while preserving the income effect.
