Sub-topics

Textile Fibres

Classification of fibres, fibre-forming polymers, structures of cotton, wool, silk, bast fibres; properties of man-made fibres (carbon, aramid, UHMWPE); polymerisation (nylon-6, nylon-66, PET, PAN, PP); spinning methods (melt, wet, dry, gel); post-spinning operations; fibre identification methods; fibre structure-property correlation

Yarn Manufacture & Properties

Ginning, carding, combing, drawing, roving, spinning methods (ring, rotor, air-jet, vortex, compact, wrap, twist-less), yarn geometry, fibre migration, yarn stress-strain, twist-strength relation, yarn irregularity

Fabric Manufacture & Properties

Winding, warping, sizing, loom motions (shedding, picking, beat-up, take-up, let-off), dobby, jacquard, shuttle-less weaving (rapier, projectile, water-jet, air-jet), knitted constructions (plain, rib, interlock, purl), warp knitting (pillar, tricot, atlas), braiding, nonwoven technologies (spun-bond, melt-blown), fabric geometry (Peirce’s equations, tightness factor)

Textile Testing

Fibre testing (length, fineness, maturity, tensile), yarn testing (twist, hairiness, evenness, tensile), fabric testing (thickness, drape, crease recovery, abrasion, air permeability, thermal resistance), objective evaluation of low-stress properties

Chemical Processing & Finishing

Fibre preparation, dyeing (cotton, wool, silk, polyester, nylon, acrylic, blends), dye-fibre interaction, Beer-Lambert’s law, Kubelka-Munk theory, printing (screen, roller, pigment, discharge, resist, inkjet, transfer), finishing (soft, wrinkle-resistant, water repellent, flame retardant, bio-polishing, anti-static), effluent treatment & pollution control
