Textile Foundations & Fibres

From molecules to fibres. The textile value chain, fibre types and identification, stress basics and the science of fibre properties.

• Introduction to Textile Engineering & Fibres — From fibre to fashion and beyond. Learn the textile value chain (fibre → yarn → fabric → wet processing → garment), natural fibres (cotton, wool, silk, jute, linen) and man-made fibres (viscose, polyester, nylon, acrylic, aramid), fibre identification, the textile industry's economic role, technical textiles, and sustainability challenges — with Python tracking material yield through each stage of the chain.
• Stress — Stress is internal force per unit area. Learn normal (tensile/compressive) stress, bearing stress, allowable stress and factor of safety, stress concentrations, and thin-walled pressure vessels.
• Fibre Science & Properties — What makes a fibre useful. Learn fibre structure (molecular chains, crystallinity, orientation), linear density (tex, denier, dtex), tensile properties (tenacity, elongation, modulus, work of rupture), stress–strain curves, moisture regain and moisture content with commercial weight, fibre length and fineness (HVI, micronaire), thermal properties (glass transition, melting), fibre spinning (melt, wet, dry) and cotton grading — with Python for linear density, tenacity, regain and invoice weight.
