Question 1: Describe the difference between woven and knitted fabrics in terms of their construction. Include at least two key distinctions.

Answer: Woven fabrics are made by interlacing two sets of yarns at right angles, creating a stable structure. Knitted fabrics are made by interlooping yarns in a series of connected loops, making the fabric stretchier and more flexible.

Question 2: Explain what is meant by the term 'plain weave' in fabric construction. How does this method affect the fabric’s appearance and strength?

Answer: Plain weave is a simple weaving pattern where each weft yarn crosses over and under each warp yarn alternately. This creates a balanced, durable fabric with a checkerboard appearance.

Question 3: List three different types of weave or knit constructions used in textiles and briefly describe their characteristics.

Answer: 1. Satin weave – a smooth, shiny surface with fewer interlacings, used in luxury fabrics. 2. Twill weave – characterized by diagonal lines, making the fabric strong and durable. 3. Jersey knit – a stretchy, soft fabric with a smooth face and a textured back, commonly used in T-shirts.

Question 4: Identify the construction method most likely used for a fabric that is stretchy and soft, such as jersey fabric. Justify your answer.

Answer: Jersey knit is used for stretchy, soft fabrics because it is knitted in a way that creates loops, allowing the fabric to stretch and recover easily.

Question 5: Sketch a simple diagram to illustrate a basic woven fabric structure. Label the warp and weft yarns.

Answer: A correct sketch would show two sets of parallel lines crossing at right angles, with one set labeled as 'warp' (vertical) and the other as 'weft' (horizontal). The crossing points indicate interlacing.

Question 6: Draw a diagram of a knitted fabric showing the interlooping of yarns. Indicate the loop formation clearly.

Answer: A correct diagram would show a series of loops linked side-by-side, with each loop passing through the previous one, forming a continuous chain. The loops should be consistent in size and shape.

Question 7: Explain why woven fabrics are generally more stable and less stretchy than knitted fabrics.

Answer: Woven fabrics are more stable because the yarns are interlaced at right angles, providing rigidity. Knitted fabrics are more stretchy because the loops can expand and contract, allowing more flexibility.

Question 8: Describe the process of creating a fabric using the 'warp knitting' technique. How does it differ from weft knitting?

Answer: Warp knitting involves knitting yarns lengthwise along the fabric, with each needle forming loops independently, resulting in a stable fabric that doesn’t run. In contrast, weft knitting uses a single yarn that loops across the width of the fabric, creating a more elastic structure.

Question 9: Identify two advantages of using woven fabrics in textile production.

Answer: Woven fabrics are strong and durable, and they have a stable structure that holds shape well, making them suitable for clothing and upholstery.

Question 10: Discuss how the choice of fabric construction affects the suitability of a fabric for different types of clothing or textile products.

Answer: The construction determines properties like stretch, strength, and appearance. For example, woven fabrics are ideal for structured garments like shirts and trousers, while knitted fabrics are preferred for stretchy clothing like activewear or T-shirts. The choice influences comfort, fit, and durability.
