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

Answer: Cotton: soft, breathable, and washable. Wool: warm, elastic, and can absorb moisture.

Question 2: Identify three synthetic fabrics and mention one advantage of using each.

Answer: Polyester: durable and resistant to shrinking. Nylon: strong and elastic. Acrylic: lightweight and warm.

Question 3: Explain the main difference between woven and knitted fabrics.

Answer: Woven fabrics are made by interlacing two sets of yarns at right angles, creating a rigid structure. Knitted fabrics are made by interlooping yarns, resulting in stretchiness and flexibility.

Question 4: Draw a simple sketch of a fabric pattern showing a plain weave structure. Label the warp and weft yarns.

Answer: A correct sketch would show a grid-like pattern with horizontal (weft) and vertical (warp) lines crossing over each other in an even, interlaced manner. Labels: 'Warp yarns' and 'Weft yarns'.

Question 5: Describe two uses for non-woven fabrics in textiles.

Answer: Non-woven fabrics are used in medical masks and disposable wipes because they are lightweight, breathable, and can be manufactured quickly.

Question 6: List three properties that make linen a popular fabric choice for summer clothing.

Answer: Lightweight, breathable, and moisture-wicking.

Question 7: Sketch a fabric swatch that demonstrates a velvet surface. Indicate the direction of the pile in your sketch.

Answer: A correct sketch would show a smooth surface with a slightly raised, plush pile running in one direction, indicating the nap of velvet.

Question 8: Compare the durability of silk and polyester fabrics. Which one is generally more durable and why?

Answer: Polyester is generally more durable because it is resistant to stretching, shrinking, and abrasion, whereas silk is delicate and prone to damage from sunlight and friction.

Question 9: Explain why some fabrics are treated with special finishes, such as water resistance or stain repellence.

Answer: Special finishes improve the fabric's performance, making it more suitable for specific uses like outdoor wear or easy cleaning, and increase longevity.

Question 10: Identify a fabric that is commonly used for upholstery and explain why it is suitable.

Answer: Cotton or polyester blends are commonly used because they are durable, easy to clean, and resistant to wear and tear.

Question 11: Sketch a design for a lightweight, breathable fabric suitable for sportswear. Include annotations about the fabric choice.

Answer: A correct sketch would depict a fabric with a mesh or perforated pattern, labeled as 'breathable mesh' or 'lightweight polyester.' Annotations should mention properties like 'airflow' and 'moisture-wicking.'
