Question 1: Define the term 'natural fabric' and give two examples commonly used in textiles.

Answer: A natural fabric is derived from natural sources such as plants or animals. Examples include cotton and wool.

Question 2: Describe two key characteristics of synthetic fabrics that differentiate them from natural fabrics.

Answer: Synthetic fabrics are often more durable and resistant to wrinkles and shrinking compared to natural fabrics.

Question 3: List three advantages of using linen fabric in clothing and interior textiles.

Answer: Linen is breathable, has a natural luster, and becomes softer with washing.

Question 4: Identify a fabric that is commonly used for sportswear due to its moisture-wicking properties. Explain why it is suitable.

Answer: Polyester is commonly used for sportswear because it draws moisture away from the skin, keeping the wearer dry and comfortable.

Question 5: Draw a simple cross-section diagram of woven fabric, labeling the warp and weft threads. (Sketch should show parallel warp threads and perpendicular weft threads crossing over them.)

Answer: A correct sketch would depict parallel vertical threads labeled 'warp' and horizontal threads labeled 'weft' crossing each other in an over-and-under pattern.

Question 6: Explain the main difference between knitted fabrics and woven fabrics in terms of their structure and stretchability.

Answer: Knitted fabrics are made from interlocking loops of yarn, making them more elastic and stretchy. Woven fabrics are made from interlaced threads, which are less stretchable.

Question 7: Sketch a fabric pattern that would be suitable for a casual shirt. Indicate the type of fabric you are designing for and justify your choice.

Answer: A sketch of a soft, lightweight cotton or linen fabric with a subtle stripe or check pattern. The justification should mention comfort, breathability, and suitability for casual wear.

Question 8: Identify a fabric that is particularly resistant to wrinkles and explain a common use for this fabric.

Answer: Polyester is resistant to wrinkles and is often used in school uniforms, workwear, and travel clothing due to its easy-care properties.

Question 9: Describe the key differences between silk and polyester fabrics regarding texture, appearance, and production process.

Answer: Silk is a natural fiber produced by silkworms, with a smooth, luxurious texture and shiny appearance. Polyester is a synthetic fiber made from petrochemicals, usually with a slightly less soft texture but similar shine, and is produced through chemical processes.
