• 12 short answer questions (2 marks) per unit with exam-ready answers.
• 12 long answer questions (7 marks) per unit with complete step-by-step solutions, diagrams and numericals.
• MOST IMPORTANT and IMPORTANT tags with a summary list for each unit.
• AKTU-format model question papers with complete solutions.

Unit-wise syllabus coverage

1. Unit 1 – Chemistry of Textile Fibres: Classification of textile fibres; natural fibres (cotton, wool, silk, jute) and their chemical composition; synthetic fibres (nylon, polyester, acrylic); physical and chemical properties of fibres; moisture absorption and swelling; fibre morphology and structure-property relationship.
2. Unit 2 – Polymer Chemistry and Fibre Formation: Introduction to polymers; monomers and polymerization; addition and condensation polymerization, copolymerization, step-growth and chain-growth mechanisms, melt, dry, and wet spinning processes, drawing and orientation, fiber crystallinity and amorphous regions, chemical modification of fibers (graft copolymerization, cross-linking), recycled and bio-based synthetic fibers (PLA, PHA).
3. Unit 3 – Textile Wet Processing Chemistry: Preparation processes (desizing, scouring, bleaching – chemistry and agents), chemistry of direct, reactive, acid, basic, vat, and disperse dyes, dye-fiber interactions and bonding mechanisms, printing pastes and thickeners, fixation chemistry, after-treatments, water and effluent chemistry in wet processing.
4. Unit 4 – Textile Finishing Chemistry: Mechanical and chemical finishing principles, softeners (anionic, cationic, silicone-based), anti-wrinkle and easy-care finishes (DMDHEU chemistry), water-repellent finishes (fluorocarbon, C6 vs C8), flame-retardant finishes (halogenated and phosphorus-based), UV protection finishes, nanotechnology in textile finishing.
5. Unit 5 – Sustainable and Functional Textile Chemistry: Environmental issues in textile industry, Green chemistry in textile processing, biodegradable dyes and natural dyes, enzyme-based processes (amylases, cellulases, proteases), antimicrobial textiles (silver nanoparticles, chitosan, zinc oxide), phase-change materials in textiles, e-textiles chemistry, recycling of textile waste, circular economy in textile industry.
