Recorded February 18, 2021
Presented by Tova N. Williams, PhD, Southeast Reagent Sales Account Manager, TCI America

Color is ubiquitous and can be produced for aesthetic and/or functional purposes.  Both natural and synthetic (man-made) colorants can be used to apply color to a variety of materials including textiles, foods, and hair.  In this presentation, an overview of color and the various colorants for the coloration of protein, polyamide, acrylic, polyester, and cotton fibers will be provided.  For example, the requirements for color to be seen by the human eye, how color can be produced, dye/pigment-fiber interactions, and technical properties that can be achieved by the application of certain colorants will be highlighted.  Come prepared to ask questions and participate in a very engaging discussion!
