What this dot point is asking
This is Edexcel key idea 1.11, the categorisation of textiles. Edexcel wants you to apply knowledge of the working properties, characteristics, applications, advantages and disadvantages of fibre types and fabric constructions so you can discriminate between them and select appropriately. This is one of the six material groups in Topic 1 core content, examined as recall and Explain or Discuss questions. The same materials appear in depth in the Textiles material category (Section B) if your school chose it.
Fibre types
- Cotton (natural, vegetable): soft, absorbent, cool and comfortable; creases easily and dries slowly. Used for shirts, denim and bedding.
- Wool (natural, animal): warm, absorbent and naturally crease-resistant; can shrink and felt. Used for jumpers, suits and carpets.
- Polyester (synthetic): strong, hard-wearing, quick-drying and crease-resistant; less breathable. Used for sportswear, linings and blends.
- Acrylic (synthetic): soft, warm and lightweight, a cheaper wool substitute; can pill. Used for knitwear and blankets.
- Blends (such as polycotton): combine, for example, cotton's comfort with polyester's strength and easy care.
Fabric constructions
- Woven (1.11.3): strong, stable and hard-wearing with little stretch. Edexcel names plain weave (calico) and twill (denim). Used where strength and a stable shape matter.
- Non-woven (1.11.4): fibres bonded or felted into a sheet. Edexcel names felted wool fabric and bonded fibres or webs. Used for interfacings, wipes and some packaging; cheap but weaker and does not fray.
- Knitted (1.11.5): loops that stretch and trap air for warmth. Edexcel names weft-knitted (stretchy, can ladder) and warp-knitted (more stable, ladder-resistant). Used for jumpers, socks and stretch garments.
Properties that decide the use
A designer matches these to the product: a stretchy elastic knit for sportswear, a durable woven denim for jeans, a warm resilient wool for a coat, a cheap non-woven felt for craft and interfacing. The skill is naming the fibre or construction property and tying it to the demand.
Exam-style practice questions
Practice questions written in the style of Pearson Edexcel exam questions on this dot point, with worked answer explainers. The year tag is the paper they imitate, not the source.
Edexcel 20214 marksExplain the difference between a natural and a synthetic fibre, giving one named example of each. (4 marks)Show worked answer →
A 4-mark question gives 2 marks for the distinction and 2 for valid examples.
A natural fibre comes from a plant or animal source and is harvested rather than manufactured (1), for example cotton (a vegetable fibre from the cotton plant) or wool (an animal fibre from sheep) (1).
A synthetic fibre is manufactured from chemicals, usually polymers made from oil, by extruding the polymer into filaments (1), for example polyester or acrylic (1).
Markers reward the source distinction (natural from plants/animals, synthetic made from polymers) and a correct example of each. Note acrylic appears as both a polymer and a textile fibre in Edexcel's content. Calling polyester a natural fibre is a common error.
Edexcel 20226 marksDiscuss the choice between a woven and a knitted fabric for a child's winter jumper. (6 marks)Show worked answer →
A 6-mark Discuss is levels-marked. Markers reward developed points on both constructions linked to the jumper.
A knitted fabric is made from interlocking loops of yarn, so it stretches, traps air for warmth and is comfortable and flexible (good for a child to move in and to put on over the head). Weft-knitted fabric stretches a lot but can ladder if a thread breaks.
A woven fabric is made from yarns crossing at right angles, so it is stronger, more stable and harder-wearing, but it has little stretch unless elastane is added, making it less comfortable for an active child and harder to pull on.
A Level 3 answer weighs warmth, stretch, comfort and durability for a child's jumper and concludes, for example, that a knitted fabric is the better choice for warmth and stretch, accepting it is less hard-wearing. Markers reward the construction details and the applied judgement.
