Module 1 — Fibre and Yarn
Covers fibre selection and yarn structures used in apparel textiles.
What you will be able to do
Link fibre type and yarn structure to the properties a buyer actually specifies: strength, stretch, pilling, hand feel and shrinkage.
The practical work
Take three fabrics from different fibre and yarn routes — combed ring-spun cotton, open-end cotton and a polyester filament — and write what each yarn structure predicts about pilling, strength, hand feel and dye uptake. Confirm your predictions against a laboratory report.
Prerequisite: No prior module required.
