Question 1: Name three natural fabrics commonly used in clothing and describe one key characteristic of each.

Answer: Cotton: soft and breathable; Wool: warm and elastic; Linen: strong and cool to wear.

Question 2: Identify two synthetic fabrics and explain how they are different from natural fabrics.

Answer: Polyester and nylon; synthetic fabrics are man-made, often more durable, less breathable, and resistant to shrinking compared to natural fabrics.

Question 3: Describe the process of how polyester fabric is made from raw materials.

Answer: Polyester is made from petrochemicals through a chemical reaction called polymerization, which produces long chains of polyester that are melted and spun into fibers.

Question 4: Sketch a piece of fabric that is described as 'smooth, shiny, and tightly woven.' Label three features that make it distinctive.

Answer: A smooth and shiny surface indicating a satin or silk-like fabric; tightly woven structure; fine, glossy appearance.

Question 5: List two advantages and two disadvantages of using synthetic fabrics in textiles.

Answer: Advantages: Durable and resistant to wrinkles; Disadvantages: Not breathable and can cause skin irritation.

Question 6: Explain why natural fabrics are generally considered more eco-friendly than synthetic fabrics.

Answer: Natural fabrics come from renewable resources and biodegrade more easily, whereas synthetics are made from non-renewable petrochemicals and take longer to decompose.

Question 7: Draw a simple fabric sample that shows a textured surface, such as boucle or tweed. Label the texture and the type of fabric it might be.

Answer: A sketch illustrating a rough, looped surface with varied yarns; label as 'Boucle or Tweed fabric.'

Question 8: Compare the uses of cotton and polyester fabrics in the textile industry. Include at least two uses for each.

Answer: Cotton: T-shirts, bed linens; Polyester: Sportswear, upholstery fabrics.

Question 9: Describe how the properties of wool make it suitable for winter clothing.

Answer: Wool is insulating, retains heat well, and has natural elasticity, making it warm and comfortable for winter wear.

Question 10: Identify which fabric type is best suited for making a waterproof outdoor jacket and justify your choice.

Answer: A synthetic fabric like nylon or polyester, because they are water-resistant or waterproof when treated, lightweight, and durable.

Question 11: Explain the difference between woven and knitted fabrics in terms of construction and typical uses.

Answer: Woven fabrics are made by interlacing two sets of yarns at right angles, making them stable and durable, used in shirts and trousers. Knitted fabrics are made by interlocking loops of yarn, making them stretchable and soft, used in T-shirts and sweaters.
