Question 1: Name three common types of woven fabrics and briefly describe how each is constructed.

Answer: Examples include: 1) Plain weave - made by weaving weft yarns over and under warp yarns alternately; 2) Twill weave - characterized by diagonal lines created by passing the weft yarn over multiple warp yarns before going under one; 3) Satin weave - where floats of yarn are floated over several yarns to create a smooth surface.

Question 2: Describe the main difference between woven 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 interlooping yarns in a series of connected loops, making them more stretchable.

Question 3: Explain what is meant by 'fabric grain' and why it is important in fabric construction.

Answer: Fabric grain refers to the direction of the warp and weft threads in woven fabric. It is important because fabric behaves differently along different grains, affecting how it drapes and how patterns align.

Question 4: Identify two advantages of using knitted fabrics over woven fabrics.

Answer: Knitted fabrics are more stretchable and more comfortable to wear. They also tend to be quicker to produce in terms of manufacturing.

Question 5: Describe the process of creating a non-woven fabric and give an example of where it might be used.

Answer: Non-woven fabrics are made by bonding fibers together through mechanical, chemical, or heat processes without weaving or knitting. An example is disposable wipes or filters.

Question 6: Draw a simple diagram to show the difference between a plain weave and a twill weave fabric. Label the key features.

Answer: A correct sketch would show a grid pattern for plain weave, with each weft crossing over and under warp yarns alternately. For twill weave, the sketch should show diagonal lines formed by the weft yarn passing over multiple warp yarns, creating a diagonal pattern.

Question 7: Sketch a design for a fabric pattern that could be used for a school uniform, considering the fabric’s construction. Use clear, simple shapes and indicate the type of weave or knit you would choose.

Answer: A suitable sketch would include a simple pattern (e.g., stripes or checks) with annotations indicating whether the fabric is woven (e.g., plain or twill) or knitted, and the pattern placement.

Question 8: Explain how the choice of fabric construction affects the durability and texture of a fabric used for outdoor clothing.

Answer: Woven fabrics, especially tightly woven ones like twill, tend to be more durable and resistant to tearing, making them suitable for outdoor wear. The texture can be smooth or rough depending on the weave, impacting comfort and protection.

Question 9: Identify two fabrics that are typically knitted and two that are woven. Mention one key characteristic of each type.

Answer: Knitted fabrics: Jersey (stretchy, soft) and ribbing (elastic, textured). Woven fabrics: Denim (tough, durable) and chiffon (light, sheer).
