Question 1: Define the term 'natural fibre' and give two examples of natural fibres used in textiles.

Answer: A natural fibre is a fibre obtained from plants, animals, or minerals that can be spun into thread or yarn. Examples include cotton and wool.

Question 2: Describe the main differences between synthetic and natural fabrics in terms of their environmental impact and durability.

Answer: Natural fabrics are biodegradable and generally have a lower environmental impact during production but may degrade faster over time. Synthetic fabrics are made from petrochemicals, are less biodegradable, but often have higher durability and resistance to wear.

Question 3: Explain why polyester is a popular choice for sportswear. Mention at least two properties that support this use.

Answer: Polyester is popular for sportswear because it is lightweight, resistant to stretching and shrinking, and dries quickly, making it suitable for active use.

Question 4: Identify and describe two finishing techniques used to improve the appearance or performance of textiles.

Answer: Examples include mercerisation, which enhances lustre and strength in cotton, and water-repellent coating, which makes fabrics resistant to water penetration.

Question 5: Design Brief: You have been tasked with creating a durable, lightweight fabric for a hiking jacket. Consider the properties needed in your fabric choice. [DRAFT SKETCH]

Answer: A suitable fabric would be a nylon or polyester with a water-resistant finish. The sketch should include a lightweight, tightly woven fabric with a water-repellent coating, possibly with a mesh lining for breathability.

Question 6: Sketch a simple cross-section diagram of a woven textile. Label the warp and weft threads clearly.

Answer: The correct sketch would show parallel vertical threads (warp) and horizontal threads (weft) crossing each other at right angles, forming a grid pattern. Labels should identify warp and weft threads.

Question 7: Discuss the advantages and disadvantages of using recycled polyester in textile production.

Answer: Advantages include reducing waste and environmental impact, and conserving resources. Disadvantages might include higher cost and potential limitations in fabric performance compared to virgin polyester.

Question 8: Identify three factors to consider when choosing a textile material for making school uniforms. Justify each factor briefly.

Answer: Factors include durability (to withstand frequent wear), comfort (for long periods of wear), and ease of maintenance (such as being easy to wash and iron).

Question 9: Create a plan for testing the colourfastness of a textile sample. Outline the steps you would take.

Answer: First, cut a small sample of the fabric. Then, immerse it in a washing solution or rub it with a damp cloth repeatedly. Finally, compare the colour of the sample before and after testing to see if any colour has transferred or faded.

Question 10: Sketch your own design for a decorative textile pattern suitable for a cushion cover. Include annotations describing the colours and motifs you would use.

Answer: The sketch should feature a repeating pattern with clear motifs such as floral or geometric designs. Annotations should specify colour choices (e.g., navy blue background with white floral motifs) and any textural details planned.
