Question 1: Describe the difference between woven and knitted fabrics in terms of their construction process.

Answer: Woven fabrics are created by interlacing two sets of yarns at right angles on a loom, forming a stable structure. Knitted fabrics are made by interlooping yarns with needles, creating a flexible and stretchy fabric.

Question 2: List three common types of woven fabrics and briefly describe their typical uses.

Answer: 1. Cotton drill - used for workwear and uniforms. 2. Satin - used for eveningwear and linings. 3. Canvas - used for bags, tents, and upholstery.

Question 3: Explain how the process of felting differs from weaving and knitting.

Answer: Felting involves matting and compressing wool fibres together using heat, moisture, and agitation, forming a dense fabric. Unlike weaving and knitting, felting does not use yarns but relies on the natural properties of wool fibres.

Question 4: Sketch a simple diagram showing the basic structure of a woven fabric, including the yarns involved.

Answer: A correct sketch would show two sets of parallel lines crossing at right angles, labeled as 'warp' (longitudinal yarns) and 'weft' (horizontal yarns), interlacing at right angles to form a grid-like structure.

Question 5: Identify the main advantages of knitted fabrics compared to woven fabrics.

Answer: Knitted fabrics are more stretchy, comfortable, and easier to produce in complex shapes, making them ideal for clothing that requires flexibility, like sportswear.

Question 6: Describe what is meant by 'bias' in fabric construction and why it is important.

Answer: The bias is the diagonal direction across the fabric, at 45 degrees to the warp and weft. Cutting along the bias allows the fabric to stretch and drape more smoothly, useful for shaping garments.

Question 7: Sketch a pattern for a simple patch pocket to be sewn onto a garment, indicating seam allowances.

Answer: A large rectangle with a smaller rectangle inside it, representing the pocket opening. Mark the seam allowance around the edges, typically 1-2cm, and indicate where the top edge may be folded over for finishing.

Question 8: Explain the purpose of finishing techniques such as hemming, binding, or edging in fabric construction.

Answer: Finishing techniques are used to prevent fraying, improve appearance, and strengthen the edges of fabric or seams to ensure durability and a professional look.

Question 9: Discuss the advantages and disadvantages of using non-woven fabrics in textiles.

Answer: Advantages include quick production, low cost, and versatility for disposable products. Disadvantages include less durability, limited stretch, and a less natural feel compared to woven or knitted fabrics.

Question 10: Identify two fabric construction methods not covered above and describe their basic process.

Answer: Non-woven fabrics are made by bonding fibres together using heat, chemicals, or pressure without knitting or weaving, commonly used for medical or disposable products. Felt is produced by matting wool fibres through agitation, heat, and moisture, resulting in a dense, sturdy fabric.
