Question 3: Identify two synthetic fabrics and discuss one advantage and one disadvantage of each.

Answer: Polyester: Advantage - durable and resistant to shrinking; Disadvantage - not breathable. Nylon: Advantage - strong and elastic; Disadvantage - can be prone to static and pilling.

Question 4: Describe the process of how a fabric made from polyester is typically produced.

Answer: Polyester fibers are produced through a chemical process called polymerization, then melted and spun into filaments or fibers, which are woven or knitted into fabric.

Question 5: Sketch a simple example of a fabric with a plain weave structure. Label the yarns as warp and weft.
