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

Answer: Woven fabrics are made by interlacing two sets of yarns at right angles, creating a stable structure. Knitted fabrics are made by interlocking loops of yarn in a series, resulting in a stretchy and flexible fabric.

Question 2: Explain how non-woven fabrics are produced and give one example of a non-woven fabric used in textiles.

Answer: Non-woven fabrics are made by bonding or felting fibers together using heat, pressure, or adhesives rather than weaving or knitting. An example is felt, which is made from pressed wool fibers.

Question 3: List three different types of weaving techniques and briefly describe each one.

Answer: 1. Plain weave: yarns cross over and under each other in a simple criss-cross pattern. 2. Twill weave: yarns create diagonal lines on the fabric surface. 3. Satin weave: yarns float over several yarns before going under one, producing a smooth surface.

Question 4: Sketch a simple diagram showing the basic structure of a knitted fabric, indicating the interlocking loops.

Answer: A correct sketch would show a series of interlocking loops arranged in rows, with each loop connected to the loops above and below, forming a continuous chain.

Question 5: Identify whether the following scenario describes a woven, knitted, or non-woven fabric: 'A fabric that stretches when pulled and is made by creating interlocking loops of yarn.'

Answer: Knitted fabric.

Question 6: Explain why woven fabrics tend to be more stable and less stretchy compared to knitted fabrics.

Answer: Woven fabrics are made by interlacing yarns at right angles, which creates a firm and stable structure. Knitted fabrics are made of interlocking loops, which allow more movement and stretch.

Question 7: Describe how non-woven fabrics are bonded together and give an example of a product made from non-woven fabric.

Answer: Non-woven fabrics are bonded through processes like heat bonding, chemical bonding, or mechanical entanglement of fibers. An example is disposable surgical masks.

Question 8: Draw a simple diagram illustrating the difference between a plain weave fabric and a twill weave fabric. Label the key features of each.

Answer: A correct diagram would show a criss-cross pattern for plain weave, with yarns crossing at right angles. The twill weave diagram should display diagonal lines, indicating the yarns float over multiple yarns to form a diagonal pattern.

Question 9: What are the advantages of using knitted fabrics in clothing? List two reasons.

Answer: Knitted fabrics are stretchy, providing comfort and flexibility. They also drape well, making them suitable for garments like sweaters and sportswear.

Question 10: Sketch a basic structure of a felt fabric and explain how it is different from woven and knitted fabrics.

Answer: A correct sketch would show compacted fibers pressed together without interlacing or looping. Felt is made by matting, pressing, and felting fibers, unlike woven or knitted fabrics which involve yarns and loops.
