Basic knowledge of general chemistry, organic chemistry and polymers.
Students will undergo an oral test, in which is evaluated their knowledge of the subject and their capability of make connections between different topics.
This course will describe under a chemical point of view main processes of the textile industry value chain, including materials and processes (dyeing, printing, finishing of textiles). Chemistry is fundamental in every step of these processes, from the knowledge of fibers composition to understanding how dyes are fixing on fibers. Evaluation of textile products will be done both under environmental and qualitative point of view. Technical and technological innovation (plasma, nanotechnologies, smart textiles) will be discussed.
Students will become able to compare costs and benefits of textiles, regarding consumption of resources, environmental balance and human care.
FIRST CHAPTER: MATERIALS
1. Fibers: mechanical properties, chemical properties, chemical composition. Natural fibers (wool, silk, cotton, linen); man-made fibers (viscose, rayon cupro, acetate); synthetic fibers (PES, acrylic, PA, elastomers, microfibers).
2. Surfactants: surface tension, chemical classification, uses and properties.
3. Dyes: chemical classification, synthesis, main dye classes.
SECOND CHAPTER: PROCESSES AND TECHNOLOGY
4. Pre-dyeing operations on cellulosic fibers, wool, silk and synthetic fibers.
5. Dyeing machines.
6. Dyeing process: kinetic and thermodynamic considerations, main factors that influence dye results, dyeing of main fibers with different dye classes.
7. Textile printing: classification of traditional printing methods and Inkjet printing.
8. Finishing operations: mechanical, chemical, dry and wet processes, specific finishing for flame resistant, waterproof and windproof properties.
9. Colour theory: light sources, interactions between light and matter, the eye and spectrometer, main colour spaces.
10. Textile resistance: resistance to washing, water, light, rubbing, sweat.
THIRD CHAPTER: INNOVATION
11. Innovation in the textile industry: new materials and technologies.
12. Sustainability, environmental issues, International statements.
