AIChE Journal Keeps You Current with Technological Advances

Article Written By: Loraine Kasprzak

Each month, the AIChE Journal publishes peer-reviewed articles on the most important and latest technological advances in core areas of chemical engineering and other relevant engineering disciplines.

This month’s open access article, “Modeling the Deposition of Fluorescent Whitening Agents on Cotton Fabrics,” by Laura Bueno,  Carlos Amador, and Serafim Bakalis discusses their investigation into the adsorption of two widely used fluorescent whitening agents (FWAs) on unbrightened cotton fabrics.

Many organic fabrics such as cotton absorb in the short UV‐region extending into the blue region of the spectrum, which promotes a yellowing shade on the textiles. FWAs are widely used in the textile and paper industry for improving and maintaining whiteness.  The research team developed a mechanistic model to describe the dissolution process of FWAs, convective mass transport into the fabrics, diffusion in the stagnant layer to the fabrics' surface, and adsorption of FWAs on cotton fabrics. Temperature, hardness of the wash liquor, initial concentration of FWA in solution, and fabric to wash liquor ratio were taken into account. Read the article here.
