Question 1: Describe the main properties of cotton fabric and explain why it is commonly used in clothing.

Answer: Cotton fabric is soft, breathable, and absorbent. It is also durable and easy to wash. These properties make it comfortable for clothing and suitable for everyday wear.

Question 2: Identify two fabrics that are known for their elasticity and describe their typical applications.

Answer: Spandex (Lycra) and elastane are fabrics with high elasticity. They are commonly used in sportswear, stretch jeans, and fitted clothing because they allow freedom of movement and maintain shape.

Question 3: Explain the difference in properties between silk and polyester fabrics.

Answer: Silk is a natural, smooth, shiny, and breathable fabric with good drape, but it can be delicate and is more expensive. Polyester is a synthetic, durable, wrinkle-resistant, and quick-drying fabric, but it is less breathable and can feel less comfortable against the skin.

Question 4: List three properties that make wool a suitable fabric for winter clothing.

Answer: Wool has good insulation, is moisture-wicking, and naturally resists wrinkles and odors. These properties help keep the wearer warm and comfortable in cold weather.

Question 5: Draw a sketch of a fabric that would be suitable for making a lightweight summer dress. Label the key properties that make it suitable.

Answer: A correct sketch would depict a lightweight, soft, and breathable fabric such as linen or chiffon. The labels should include properties like 'lightweight,' 'breathable,' 'soft texture,' and 'good drape.'

Question 6: A fabric is described as being 'water-resistant but not waterproof.' Explain what this means and give an example of a fabric with this property.

Answer: It means the fabric can repel water to some extent but will eventually allow water to pass through if exposed for a long time. An example is polyester treated with a water-resistant coating.

Question 7: Compare the durability of nylon and linen fabrics and suggest suitable uses for each.

Answer: Nylon is highly durable, resistant to abrasion, and long-lasting; it is suitable for outdoor gear and activewear. Linen is strong but tends to weaken when wet and wrinkles easily; it is suitable for casual clothing and home textiles like curtains.
