Coloration of cotton fibers with inorganic pigments using a transient high-temperature technology

Abstract

Inorganic pigments have received considerable attention due to their color brilliance and thermal stability, which results in beautiful visual effects and desirable specific functions. Herein, we demonstrated a strategy for the coloration of cotton fabrics coloring with inorganic pigments using a transient high-temperature coloration method. The uniform color, excellent brilliance, and satisfactory fastness were given to the cotton fabrics after the coloration process. The cotton fabrics could be also colored by a mixture of various inorganic pigments. Meanwhile, the colored cotton fabrics exhibited improved heat conduction compared with the control sample, showing an increase in surface temperature by 2 °C. The heating conduction rate of cotton colored using inorganic pigments was also superior to the raw cotton fabric. Therefore, the proposed transient high-temperature coloration technology using inorganic pigments may be a potential industrialization method to improve coloration and functional properties in cotton applications.
