- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Why it matters
This objective helps connect The use of finishes to exam-style questions, flashcards, and revision notes for The use of finishes.
Quick student answer
What is the primary purpose of laminating fabrics?
Direct answer
The primary purpose of laminating fabrics is to increase their durability and water resistance.
Key terms
- Laminated Fabric: A fabric made by bonding two or more layers together, often incorporating a waterproof or breathable membrane.
- Membrane Layer: A thin layer in laminated fabrics that provides specific properties such as waterproofing or breathability.
Common trap
Confusing Laminated Fabrics with Coated Fabrics: Laminated fabrics consist of multiple layers bonded together, while coated fabrics have a single layer coated with a substance for water resistance.

- Fabric finishes The effects of finishes and the reasons they are needed in relation to: • the fibre/fabric properties • end use of the product.
The use of finishes
- Mechanical finishes A range of mechanical finishes, including: • brushing/raising • calendaring • embossing • heat setting using thermoplastic fibres to give permanent pleats or crinkles and make fabric non-crease and non-shrink • stone and sand washing.
The use of finishes
- Understand how the physical characteristics of fabrics can be modified by using mechanical finishes, eg trapped air acts as an insulator, air supports combustion, smooth fabric reflect light better than those with texture. 22 Visit aqa.org.uk/7562 for the most up-to-date specification, resources, support and administration Chemical finishes A range of chemical finishes, including: • mercerisation • flame retardancy, eg Proban ® and Pytovatex® used on cotton fabrics • water resistance • non-iron/crease resistance, eg Teflon • shrink resistance and anti felting • moth proofing • anti-pilling • hygienic (sanitised).
