Question 1: Describe the key differences between woven and knitted fabrics in terms of their construction and typical uses.

Answer: Woven fabrics are made by interlacing two sets of yarns at right angles, resulting in a stable structure suitable for formalwear and upholstery. Knitted fabrics are created by interlooping yarns in a series of connected loops, making them more stretchable and elastic, ideal for casual wear and sportswear.

Question 2: Explain how the method of fabric construction affects its durability and stretchability.

Answer: Woven fabrics tend to be more durable due to their tight interlaced structure but generally lack significant stretch unless elastane is added. Knitted fabrics are more elastic and comfortable because of their looped structure, which allows for stretch, but they can be less durable and prone to snagging.

Question 3: Identify three different types of woven fabrics and give a brief description of each.

Answer: 1. Canvas: a plain weave fabric that is heavy and durable, used for upholstery and bags. 2. Satin: a weave with a glossy surface on one side, used for evening wear and linings. 3. Twill: characterized by diagonal ridges, strong and drapey, often used in jeans and workwear.

Question 4: Describe the process of creating a terry cloth fabric and its typical uses.

Answer: Terry cloth is a woven or knitted fabric with loops on the surface that trap air and moisture, making it highly absorbent. It is produced by adding extra yarns to form loops, commonly used in towels and bathrobes.

Question 5: Sketch a simple diagram illustrating the difference between a woven fabric and a knitted fabric. Label the key features.

Answer: A correct sketch would show a grid-like pattern with interlaced yarns for the woven fabric, and interlooped loops for the knitted fabric. Labels should include 'interlaced yarns' for woven and 'interlooped yarns' for knitted.

Question 6: Explain how the use of different yarn types can influence the construction and final properties of a fabric.

Answer: Different yarn types, such as cotton, polyester, or elastane, affect the fabric's strength, elasticity, texture, and appearance. For example, adding elastane provides stretch, while polyester can improve durability and wrinkle resistance.

Question 7: Describe a scenario where a non-woven fabric would be preferred over woven or knitted fabrics, and explain why.

Answer: Non-woven fabrics are preferred for disposable items like medical masks or wipes because they can be produced quickly and cheaply, and do not fray or unravel like woven or knitted fabrics.

Question 8: Draw a cross-section of a knitted fabric showing at least two different types of stitches. Label each stitch type.

Answer: A correct drawing would depict loops interconnected in a series, with different stitch patterns such as a plain knit stitch and a purl stitch. Labels should identify each stitch type clearly.

Question 9: List three advantages and three disadvantages of using woven fabrics in fashion design.

Answer: Advantages: 1. Strong and durable. 2. Stable and less stretchy. 3. Wide variety of textures and finishes. Disadvantages: 1. Less flexible and stretchy. 2. Can be heavy. 3. Prone to wrinkling.
