Question 2: Explain why polyester fabric is often used in sportswear.

Answer: Polyester is lightweight, quick-drying, and resistant to shrinking and wrinkling, which makes it ideal for active wear.

Question 3: List three fabrics that are good insulators and explain why insulation is important in textiles.

Answer: Wool, fleece, and thick felt are good insulators because they trap air, which helps retain body heat. Insulation keeps the wearer warm.

Question 4: Identify a fabric that is known for its elasticity and describe a clothing item where this property is beneficial.

Answer: Spandex (also known as Lycra) is elastic, making it ideal for items like sports leggings or swimsuits where stretch is needed.

Question 5: Draw a simple sketch of a fabric that is waterproof and explain how its properties are achieved.

Answer: A correct sketch would show a fabric with a shiny, smooth surface, indicating a waterproof coating or membrane. Its properties are achieved through treatments like coating or lamination, which prevent water from passing through.

Question 6: Compare the properties of silk and wool, and suggest which fabric would be better for a winter coat and why.

Answer: Silk is smooth and lightweight but not very insulating, while wool is thick, warm, and insulating. Wool would be better for a winter coat because it retains heat.

Question 7: Explain how the fabric’s breathability affects comfort in clothing.

Answer: Breathable fabrics allow moisture and air to pass through, helping keep the wearer dry and comfortable, especially during physical activity.

Question 8: Sketch a fabric that is both lightweight and durable. Label the key features that contribute to these properties.

Answer: A correct sketch would depict a fabric with a tight weave or knit, possibly showing a smooth surface. Labels might include 'tight weave' and 'strong fibers' to indicate durability and lightness.
