Course detail

Laboratory Classes in Textiles and Sorbents

FCH-BCO_TAS_PAcad. year: 2012/2013

The course includes practical demonstrations of selected experimental procedures on textile chemistry and sorbents. Practical excersises are focused on the identification of textile fibers by chemical and combustion tests, coloring and other textile-finishing treatments (dyeing and printing , fireproof, waterproof finishing, etc.) objective evaluation of color and other properties of textiles (eg creasing) and the experimental determination of the fundamental equilibrium and kinetic parameters of sorption processes.
