Module 2 — Materials and their recovery routes
How fibre, yarn and fabric construction change what can be recovered.
Fibre type is only the first variable. Staple length after shredding, yarn twist, fabric construction and finish chemistry all decide whether recovered material can go back into apparel yarn or drops into insulation and wiping cloth. This module covers fibre, yarn, weaving and knitting with recovery in view.
By the end of this module: Match a fabric to the recovery routes actually open to it, and name why the others are closed.
Prerequisite: Module 1 — you need the specification view before the material view.
