The primary course purpose is to gain a strong fundamental understanding of the chemistry and technology of preparation, dyes, dyeing and finishes. Emphasis will be on the chemistry of different bleach activators, surfactants, photophysics and photochemistry of FWAs, modulations of dyes structures to influence color, tinctorial strength, light fastness, wash fastness and aggregation. Chemistry of different dye classes will be studied with emphasis on structure-property relationships and dye-fiber interactions. Dyeing isotherms (Nernst and Langmuir), kinetics of dyeing with emphasis on derivation of Nernst and Langmuir based on thermodynamics and kinetics principles will be covered with practical examples of dyeing at different temperature and how to calculate thermodynamic parameters of dyeing (entropy, standard affinity and isotherm constants of Nernst and Langmuir). Chemistry of different finishes, including soil release, chemistry of flame retardants and mechanisms of flame retardancy, antimicrobial and water and oil repellency, will be covered with emphasis on structure-property relationships.

Prerequisite: Graduate Standing and C or better in CH221 or CH225 and CH223 or CH227

The course covers advanced aspects of processing fibers or filaments into yarns and the interrelation between the yarn mechanics and structure, geometry, and properties of fiber assembly. The theme is the influence of fibers' measured properties on the quality of subsequent yarns and fabrics. The issues associated with the development of a universal model for the prediction of yarn properties, including the role of test methods on reported values, the impact of fiber blends, various parameters associated with quality in textile products including difficulties associated with a definition of "quality" and how all of these impact yarn costs.

Typically offered in Spring only

This course is offered alternate even years

The course covers different aspects of the processing of yarns to products (braided, knitted, woven, and their composites) and the interrelation between the production mechanics and structure, geometry and properties of fiber assembly. Topics in the field are assigned and each student is expected to thoroughly study the topics and write critical papers based on structured assignments and specific questions. Conduct projects from concept to fabric formation, analyses, and evaluation.

This course provides an overview of the unique features of polymer materials that distinguish them from those composed of small-molecules or atoms (Polymer Physics) and the connections between their detailed molecular structures and their properties which produce distinctions between them (Polymer Chemistry).
