The chemical nature of the agents is studied and related to their properties. The technical uses are evaluated on this basis. Timely reports are required concerning recent advances in the manufacture, modification, dyeing and finishing of synthetics and blends. The more complex styles of printing, discharge and resist, are covered in detail. The preparation of white and colored print paste for all classes of dyed backgrounds is investigated.
Attention is given in dyeing ground shades for discharge printing.
Special effects such as Plisse, Burn-out and Vigoreaux styles are considered. This course is more comprehensive than that given in the undergraduate course. Greater detail is provided concerning the mechanisms used in the application of specialized finishes and the chemical reactions involved. The mechanics of dyeing, printing, and finishing. The structures of dyes and textile fibers, detergency and scouring, and dyeing equipment and procedures.
