TE/TC 598 is a 3-credit, intermediate course on fiber manufacturing technologies for the major classes of polymeric and inorganic fibers. The course explores innovations in fiber spinning that were necessitated by advances in polymer chemistry, the need for advanced material properties, as well as socio-economic concerns. The chemistry of polymers is discussed in terms of its role on fiber manufacturing by melt and solution spinning technologies. The microstructure and performance properties of fibers are discussed in context of the manufacturing technology.

Advances in biotechnology allow us to: better understand the biosynthetic origins of textile materials from agricultural, animal and microbial sources; apply biotechnology, such as enzyme treatment, for textile modification and waste management; and, develop new types of biobased textiles using biocatalytic and fermentation technologies. In the context of this course, biobased textile materials include materials of biological origin used as textiles (e.g. fibers, monomers and fiber-forming biopolymers) or used during the production of textiles (e.g. enzymes, microorganisms, dyes and chemicals). The origins and properties of biobased textile materials are explored in a manner that bridges the fields of polymer chemistry, biochemistry and fiber science, with emphasis on chemical composition, properties, processes, analytics and mechanisms important to using these materials for textile applications. Sustainability attributes of biobased materials are discussed throughout the course.

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.
