The nature of colour, physical principles (basis) of colour (color). Colour (color) and dyestuff. Colour vision. Colour description/specification systems. Additive and substantive mixing of colours, the CIE system of colour specification., calculation of tristimulus values from reflectance (R?) values. Determination of dyestuffs - classification - Color Index. Technological class of dyestuffs - dyestuffs for cellulosic materials, vegetable fibers and chemical (man-made) fibers. Interaction of dyestuffs and fibers types, bound and interaction of dyestuffs on fibers. Direct, vat, reactive, sulfur and isoluble azoic dyestuffs for cellulosic materials; acid, metal-complex dyestuffs, mordant and reactive dyestuffs for protein fibers. Dyeing of chemical fibers with disperse dyestuffs. Dyeing of acrylic fibers with cationic (basic) dyestuffs. Pigments. Sorption and of dyestuffs on textile fibers and diffusion into polymers of fibers. Synthesis of dyestuffs - the principles of synthesis of basic group of textile dyestuffs - (colorants). Optical brightening (fluorescent brightening) of textiles, its application in paper and detergents production; physical principles of optical bleaching.
