Objective: Introduces color science as related to human perception and practical problems to the textile industry. Studies different types of dyes available, fibers to which they are applied and properties of dyes. Introduces various finishing techniques used for textiles.
1. Color Chemistry
2. Dyeing
3. Finishing
1. Color Chemistry
a) Physical Aspects of Color
- energy sources and standard illuminants
- absorbance and transmittance of colored solutions
- Beer-Lambert Law
- reflectance measurements
- Kubelka-Munk relationship
- spectrophotometers
- additive and subtractive color mixing
b) Psychological Aspects of Color
- human eye as a light detector
- theories of color vision
- basic principles of photometry and tristimulus colorimetry, X,Y,Z, coordinates, the CIE chromaticity diagram
- Munsell and Ostwald color charts
c) Applications of Color Measurement
- specification and use of color tolerances in color matching
- prediction of dyeing recipes, metamerism and dyeing costs
d) Fluorescent Whitening Agents
- nature of fluorescent whitening agents
- measurement of fluorescence in solution and absorbed onto fabric
- specification and measurement of surface whiteness, use of whiteness scales
2. Dyeing
